I started testing smartphones known to be unbreakable with the Ulefone Armor 7, I didn't expect much but I was positively surprised by the phone but also by the number of visitors for this test.[b][b]I made a second attempt with the Doogee S58 Pro and came to the same conclusion. So I let myself be tempted by the Umidigi Bison which offers a better price/performance ratio than the other two. From an aesthetic point of view, it also stands out from the other two, it has a less rough and more neat appearance. [b][b]The Umidigi brand is not very well known in Europe but this is the fourth model of this brand that I'm testing, so I'm going to see if this small Chinese manufacturer has progressed since my last test.[b][b][b][b][b]linkManufacturer web site:https://www.umidigi.com[b]linkSite where I have bought the Umidigi Bison: https://www.banggood.com/custlink/mm3YFkWmjy[b]
Structure of my tests
I test the phones according to a pre-established structure (see below) to provide you with as much information as possible. Unfortunately, this takes a long time. Some tests like network performance tests take several days and for photo tests I sometimes have to wait until the weather is suitable to take pictures in good conditions. I am therefore obliged to publish the tests step by step, so I invite you to come back if the test is not complete at the time of your visit.[b] How are my tests different from others on the web?
- I usually buy the devices with my own money, so price is just as important as you are! - I keep the devices for at least a few weeks (sometimes more) to see what they are worth in real conditions. - I answer (when possible) your questions to help you decide before you buy - no one pays me to do these reviews, so I'm completely neutral and independent... - My pages are not filled with ads

Timeline
28/10/2020: I order the Umidigi Bison on Banggood for 129€.[b]10/12/2020: after more than a month's wait, I finally get the phone and the test can start.[b][b]
Why this phone?
When I buy rugged smartphones I know that I always have to make sacrifices on common features such as photo quality. [b][b]With this Umidigi Bison, I was tempted because it offers performance equivalent to the Redmi Note 9 for a lower price. It uses a Sony IMX 586 sensor that has already proven itself on many other phones, I have never seen this sensor in a phone in this price range before.[b][b]I also find Umidigi's usual generosity in terms of memory, 6GB / 128 Gb for a phone under 150€ is very rare. This generosity also comes through a large 5000 mAh battery. Umidigi has always managed to stand out in both of these areas.[b][b]However, not everything is perfect at Umidigi. They have never been able to offer a phone with good photo processing, the operating system wasn't always up to scratch but I haven't tested Umidigi for almost 10 months now, so I'm curious to see if the situation has improved.[b][b]
Unpacking
[b][b]The Umidigi Bison's box is really very basic, the previous models of the brand were a little better highlighted with the packaging. It doesn't matter but the difference with the previous models is obvious.[b][b]The box contains the minimum essentials with the phone, a cable, a charger and a manual. The phone, on the other hand, made a better impression on me than the packaging. For a phone of this type, it looks less rough than the previous phones I tested.[b][b]

First configuration
Umidigi uses a pure Android version, which means that they have not changed the experience by adding unwanted applications. The initial configuration therefore follows exactly the same path as all phones on Android without modification.[b][b]
Finish
[b][b]Telephones like the Umidigi Bison are generally not very beautiful, they don't play the card of elegance and finesse. Those who buy this kind of phone probably don't pay much attention to aesthetics. However, the Umidigi Bison manages to distinguish itself by offering an elegant design for a phone of this kind. Although the phone is still a bit rough and massive, Umidigi has taken a big step towards a wider audience.[b][b]The Umidigi Bison is quite large, it is as long as a Poco F2 Pro but much thicker. This is a common point with the Ulefone Armor and the Doogee S58 Pro. The phone is actually smaller but is protected by a plastic armour to better absorb shocks. The 5000 mAh battery also plays a role in its thickness.[b][b]The Umidigi Bison has a rather peculiar configuration with a fingerprint sensor on the left side of the phone, so it is with your index finger that you will have to unlock the phone and it is better to have a big hand to reach the fingerprint sensor, it is a rather curious choice. A little below the fingerprint sensor, Umidigi has placed a button which is associated with a voice note application. It surprised me a bit at first but it's a great idea, it avoids taking notes. I'll probably have to get used to it but I've often pressed this button by accident.[b][b]On the right are the usual volume and power buttons. These buttons don't stick out much from the edge of the phone and it will take a bit of getting used to finding the buttons by touch. A little further down, Umidigi has added a button that opens the camera directly, this is also a very good idea.[b][b]At the back the phone has an almost completely smooth back, which is quite rare for this kind of phone. A speaker output is placed at the back and the photo module is at the top left with a main sensor accompanied by an ultra wide angle sensor, a depth sensor and a macro sensor. The sensor for selfie is present in the form of a notch quite visible on the screen.[b][b]The Umidigi Bison therefore differs positively from the Ulefone and Doogee with some good ideas and a more neat appearance.[b][b]

Specifications
[b]The information below comes from the Device Info HW application. The application provides detailed technical information about the tested phone.
[b][b]The Umidigi Bison is equipped with a Mediatek Helio P60 processor. Umidigi is obviously recycling as this processor was already used in the Umidigi F1, I have more recently tested the Oukitel C21 which uses the same processor. The Mediatek Helio P60 is an entry-level processor that allows you to use the phone comfortably for most everyday tasks. It is not designed to play big games.[b][b]For the graphics part, the Umidigi is equipped with an ARM Mali G72 graphics processor that is also found in many other Umidigi models, such as the Samsung Galaxy A50, the Oppo A9 or the Oukitel C21. This is also an entry-level processor that does a good job for everyday tasks.[b][b][b]
Benchmark Antutu/3DMark
With an entry-level CPU and GPU, you should not expect a big score on Antutu. I got a score of 172448 points on Antutu v8, this ranks the Umidigi Bison slightly below a Redmi Note 9 for a slightly lower price. The Umidigi Bison therefore offers a good price/performance ratio.[b][b]

Note: this ranking only contains the phones I tested as well as a few others that I added for reference. [b]Gaming[b]To test the performance in game, I download the mobile PUBG game and evaluate the in-game experience, graphics level and depth of vision. This game is quite demanding and should help you evaluating the performance of a phone.[b][b]The Umidigi Bison is not a gaming phone, but it offers sufficient performance to play most mobile games. PUBG Mobile works without any problems, the gaming experience is completely correct. On the video you can see quite clearly that the textures load at the last moment and that the depth of vision is not very important but this does not spoil the gaming experience.[b][b][b]
Network performance
Umidigi has always been generous in frequency coverage and this is also the case for this Umidigi Bison. It supports 22 frequencies in 4G, which is quite rare![b][b]

The frequencies displayed below will allow you to see if this phone is compatible with your operator or if you will be able to use it in the country where you are going on vacation.
Signal 4G (before december 2020)[b]The ability to pick up the network correctly is an essential element for a phone but it is only very rarely measured. To measure a phone's ability to pick up the network, I perform a large number of measurements on the same cells to be able to compare phones under similar conditions. The signal is measured in dBm, a value of -90dBm indicates a worse signal than -70dBm. These measurements are therefore taken under real conditions and not in a laboratory, they are not scientific but give a good indication of performance. [b][b]Network signal sensitivity rating

[b][b]Signal 4G (from December 2020)[b]I decided to change the methodology for measuring the network because I noticed that the configuration of the mobile network changes over time. This makes it more difficult to compare phones because the conditions are no longer exactly the same.[b][b]To overcome this problem, I set up a device that captures 24 hours a day about ten parameters from the mobile network (ex: cell id, rssi, rsrq, snr, frequency,...). I then place the phone next to the device for 24 to 48 hours taking the same measurements so that I can compare them. [b][b] Overview of the phones tested with this methodology[b][b]

[b][b]This Umidigi Bison is not the first Umidigi I have tested and the other models have never shone in terms of network sensitivity. In the 4G performance ranking, Umidigi's were generally in the bottom positions.[b][b]Is this still the case with this model? No, Umidigi has really improved a lot. I still don't have many measurements with my new test protocol, but Umidigi is not at the bottom of the ranking.[b][b]I have made more than 2300 measurements where the average signal deviated by 3.75 dBa from the reference, the difference between the minimum and maximum was above average. This shows that this phone is more sensitive to network fluctuations. [b][b]
[b][b]The graph shows the measurements taken by the reference device and the Umidigi, the signal level should be the highest. The Umidigi never exceeds the reference but the deviation is within the good average of my measurements.[b][b][b][b]Download/Upload speed[b]To test the download speed, I have identified some 4G cells offering good performance where I test all my devices several times to see what download and upload speed they can achieve.[b]Top 10 - speed ranking in download 1.

Number of smartphones in the ranking:30 Position of this smartphone in the ranking:0/30
Note: the theoretical maximum speed of a telephone is often limited by the configuration of the mobile network and the congestion of the network at the time of the measurement. So maybe you could get a higher speed on another network [b][b]
Wifi performance
To test a phone's ability to receive the network properly, I take measurements near my router and then remotely (and always at the same place). This gives me an average in dBm where a value of -90 dBm indicates poorer performance than a value at -30 dBm.[b]
Wifi frequencies : 802.11a, 802.11b, 802.11g, 802.11n, 802.11n 5GHz, 802.11ac Download speed : 306 Signal / close : -28 Signal / distant : -75
Wifi signal[b]I measured a -25 dBm signal near the router and a -75 dBm signal at a distance. The Umidigi is in the middle range for the measurement close to the router. For the remote measurement it is at the bottom of the ranking, so the distance will play an important role in the signal quality.[b][b][b]Top 10 - wifi sensitivity ranking 1. Poco F2 Pro -11dBm 2.

Number of smartphones in the ranking:72 Position of this smartphone in the ranking:33/72
Note: I have a 400Mbps line and a modem capable of delivering higher speed, but I can never be sure how much bandwidth is available when doing a test. [b]
GPS performance
[b]To test the quality of the GPS signal I use the Offline Maps application and I make the same train trip in pedestrian mode. Why? In pedestrian mode, the GPS does not artificially correct the signal to stick to the road, it has no markings, so you can see the actual position. I then use an application to measure the accuracy of the signal. [b][b]The Umidigi Bison is equipped with a Mediatek processor, which often results in good gps performance. I measured an accuracy level of 2 metres, which is not the best score I've ever achieved but it's still a good score.[b][b][b][b]Top 10 - GPS accuracy ranking 1. Poco M5 1m 2. Poco X4 Gt 1m 3.

Number of smartphones in the ranking:44 Position of this smartphone in the ranking:17/44
Note: An accuracy of 3 meters or less can easily be corrected by a good GPS application. Phone performance also plays a role in how fast your display updates, so good accuracy could be compromised by too slow a display. [b]
Battery range
Capacity : 5000 Fast charge : Yes W max : 18 Range (100% brightness) : 550.00 Range (50% brightness) : 1471.00 Charging time : 238.00 Discharge speed (100%) : 0.18 Discharge score (100%) : 9.09 Discharge speed (50%) : 0.07 Discharge score (50%) : 3.40 Charging speed : 0.42 Charging score : 21.01
From March 2020, I replaced my subjective battery test with a technical test to better measure the real behaviour of the battery. Now I test the autonomy and charging time under absolutely identical conditions. I perform several measurements, so this test alone takes several days during which I cannot use the phone for anything else.
Battery life - methodology To test the battery life, I measure the battery consumption every minute in strictly identical conditions to be able to compare phones and also to allow you to evaluate your phone in the same conditions. I rule out any influence of applications that could interfere with the measurement. The autonomy is not linear, the battery sometimes discharges much faster at the end. This is a frustrating phenomenon but with my measurements, you will know if you need to find a charger quickly.
Battery life The battery of the Umidigi Bison has a capacity of 5000 mAh and has discharged from 100% to 1% in 550.00 minutes with 100% brightness, it has discharged from 100% to 1% in 1471.00 minutes with 50% brightness. I obtain in this way an average discharge speed of 0.18% per minute with 100% luminosity and 0.07% per minute with 50% luminosity, the consumption is therefore 9.09 mA per minute with 100% luminosity and 3.40 with 50% luminosity. To be able to compare the efficiency of the phone and its influence on the battery, you have to compare the 9.09 (or 50%) score with that of other smartphones, the figure should be as low as possible.
Charging time - methodology To test the charging time, I always use the same charger with the same cable. I measure the charging time minute by minute to see the evolution of the charge as well as the charging speed. The charging speed of a battery is not linear, it is often faster at the beginning and slower at the end. The charger is compatible with fast charging.
Charging time The battery of the Umidigi Bison has a capacity of 5000 mAh and has been charged from 1% to 100% in 238.00 minutes. This gives me an average charging speed of 0.42% per minute and therefore an increase of 21.01 mA per minute. To compare the performance of the Umidigi Bison compared to other phones, you should use the 21.01 per minute score, this score should be as high as possible.
Important note: the charging speed is not always linear, the graph below gives you an indication of the battery behaviour.
The following table lists the phones tested with the technical battery test, they are ranked in order of efficiency. A higher battery capacity should logically result in a higher battery life but it is not always the case and it does not give any indication of the efficiency of a phone.

helpHow to read these figures? The battery capacity is an important element in determining the autonomy of a phone but it is not the only factor. A phone with a large battery may have a shorter battery life if it consumes more power. If I had to take an example from everyday life, I would use the universe of the car. If a car has a large fuel tank, it should be able to drive a longer distance unless its average fuel consumption is higher. The battery efficiency score works the same way, it should be as low as possible and represents the energy consumption of the phone. These differences in efficiency are often related to the brightness of the screen, large bright screens will tend to consume more energy and even if they have a large battery, their range will be shorter.
In summary The Umidigi Bison has a 5000 mAh battery and with this kind of capacity you can normally last for several days. However, this battery is not very efficient because for almost the same battery capacity, the Redmi Note 9 lasts about 100 minutes longer at 100% brightness and saves 400 minutes with a display at 50% brightness. It is mainly the very bright screen of the Umidigi that explains this difference.[b][b]Charging speed is also below average, it took me 238 minutes to charge the battery whereas with the Redmi Note 9 it took me 162 minutes.[b][b]
Photo camera test
To test the quality of photos produced by a phone, I do a technical test (resolution, sharpness, chromatic aberration,...) in studio (identical conditions) to evaluate the technical part objectively. From the second half of 2020, I built my own laboratory to take completely objective technical measurements. I then take pictures in real conditions to see how the camera performs. I then evaluate these photos according to my criteria but I publish the photos so that you can evaluate the result according to your criteria.[b]
Hardware
Selfie / resolution : 24 Selfie / sensor : Sony Exmor RS Resolution : 48 Sensor : Sony IMX586 Exmor RS mm wide angle : 7.03 mm
The Umidigi Bison is equipped with a Sony IMX 586 main sensor. This sensor is used in many mid to high-end phones such as the OnePlus 8T which costs more than 400€. [b][b]Umidigi has always used good sensors but has always spoilt the quality of its sensors with poor image processing. The Bison Umidigi makes improvements where other Umidigi's had weaknesses, so I'm curious to see what the photo test will reveal.[b][b]I tried to install Gcam on this phone but the application crashes as soon as it is launched.[b][b]Default app[b]The default photo application of Umidigi Bison does not offer many possibilities, which has the advantage of making it easier to use. In addition to the usual photo and video modes, it is also possible to use portrait and night mode. The setting possibilities are limited, the photo mode only gives access to one sensor with the possibility of using HDR.[b][b][b]
Photo quality
Photo test / studio[b]
[b][b]The studio test is going to be very quick because the Umidigi Bison doesn't offer many adjustment possibilities, so I'm only going to take two pictures with the main sensor. The main sensor is a Sony sensor and this type of sensor generally does well in the studio. This can be verified once again with this Umidigi because the photo is well exposed, the colours are correctly saturated and the sharpness is good. The depth of field looks quite small though as I usually manage to see a larger part of the car in the sharpness area. The quality of this photo is equivalent to what I got with mid-range phones.[b][b]
[b][b][b][b]Photo test / sunny[b]
[b][b]Umidigi has a long tradition of failure in photo processing. I have tested the Umidigi F1, Umidigi F2 and the Umidigi S3 Pro. These 3 phones used a good photo sensor but with poor image processing which ruined the quality of the photo. The colour temperature was too hot and each photo was too reddish. Is this still the case with the Umidigi Bison? Yes, but the situation has improved a lot. The HDR mode helps to alleviate the problem, the use of the night mode in full daylight can under certain conditions also produce good photos.[b][b]The photos produced by the Umidigi Bison are probably not comparable to what a mid-range phone can produce (e.g. Poco X3) but it does produce better photos than the other robust smartphones I have tested. The colour temperature is a bit too high, the sharpness is sometimes a bit forced to the point of losing detail and the colours could be more saturated but for less than 150€, the result is quite acceptable. I also notice irregular areas of blur that should not be present. It's as if the sharpening treatment didn't manage to treat the whole photo.[b][b]All this may seem a bit theoretical, so I will use a photo taken in the same place and at the same time with a Xiaomi Mi 10T Pro. The comparison is not very honest as this phone costs more than 500€ but it gives a better understanding of what is missing from the Umidigi.[b][b]
[b][b]You will probably find a lot of sites that will criticize the quality of the photo but it is like comparing the top speed of a Dacia and a Porsche, it makes no sense and a Dacia is probably enough for most people. To sum up, I would say that it is possible to get better photos but in this price range and especially for this type of phone (robust phone), the Umidigi does a good job.[b][b]
10add_a_photo
[b][b][b]Photo test / cloudy[b][b]Test photo / night[b]
[b][b]The Umidigi has a night mode that will combine several photos into one to produce a brighter picture. I always come back with the price argument but it is also true here because a phone with a night mode for less than 150€ is quite rare. Thanks to the night mode, the Umidigi will allow you to take night photos without too much difficulty, you obviously need a minimum of light as on the photos I took for this test. Here too the colours are a little too warm but this problem is less visible than for daytime photos. Some photos also show a lot of digital noise.[b][b]The recomposition of the photos sometimes works correctly, sometimes not. Here also I notice blurred areas that cannot come from the optical block, these blurred areas are not always in the same place, they are therefore the result of image processing.[b][b]So this Umidigi is not the phone of the century for night photos but in this price range it does rather well.[b][b][b]

Video quality
Stabilisation[b][b][b]The Umidigi does not have video stabilisation, so it is not very shock resistant, even when walking. When I saw the videos again, I felt like an elephant walking in a forest.[b][b]Video normale conditions[b][b]The Umidigi is capable of filming in 1080p and for static scenes like this it produces an acceptable result for this range of phones. Sharpness is sometimes a bit forced, the colours are too warm and transitions from light to dark areas occur in jerks.[b][b]Video low light[b][b][b]Night video is not of very good quality, which is rarely the case in this price range. The Umidigi can't focus properly even if I don't move very fast. There is also a delay in the display because the phone can't process the video stream fast enough.[b][b]
Audio quality
To test the quality of the phone's audio output, I connect the device's audio output to a measuring tool, then play sounds on all frequencies and measure the differences between the original sound and the sound produced by the phone. In this way I measure the phone's ability to correctly reproduce all sounds.[b]
Frequency Response[b]This test is intended to test the device's ability to correctly reproduce all frequencies. The white line in the middle of the graph is the ideal situation and the other colors come from tests on different phones. A deviation from the reference line indicates a deviation from the ideal situation. To see good sound at all frequencies, it is therefore necessary to get as close as possible to the reference line.
[b][b]This graph shows that the Umidigi Bison is capable of reproducing most frequencies quite accurately, its performance is very similar to Redmi Note 9. The difference becomes more pronounced in the high frequencies but the difference is negligible especially in this price range.[b][b]Dynamic Range[b]This test is designed to test a phone's ability to play sounds at different volume levels. Here too, the phones must be as close as possible to the reference.
[b][b]The Umidigi Bison delivers a powerful and well-controlled sound because even at maximum volume, the level of distortion is very low. I'm positively surprised because this type of phone is not usually very sharp and yet this Umidigi Bison is capable of producing a powerful sound while maintaining a good level of quality. Umidigi has made great progress![b][b]Noise Level[b]This test aims to identify if the device under test is able to reproduce sounds without too much noise. A high score indicates a low parasite rate, a lower score indicates a higher presence of parasites.
[b][b]I haven't seen any interference problems and I have to admit that I didn't expect such good results from a robust phone. The other phones I have tested do not sound as good.[b][b]
Screen quality
To test the screen, I use a colorimetric probe that measures the color accuracy of a screen, as well as other parameters to see if a screen is able to correctly reproduce an image. I also test the brightness level to determine if the screen will be able to display an image in full sunlight.[b]
Screen size : 6.3 Resolution : 1080 x 2340 Ratio : 19.5:9 Protection : Corning Gorilla Glass Type : LCD IPS % occupancy : 75 dE white : 8.0 dE red : 5.3 dE green : 3.1 dE blue : 2.5 dE jaune : 5.4 dE cyan : 5.4 dE magenta : 3.2 White temperature : 7500 Contrast : 1545:1 Brightness : 598
Colorimetry[b]
[b][b]The Umidigi Bison offers a 6.3-inch screen with a resolution of 1080x2340. For a phone of this type, it is rare to have such a large screen size and especially with such a good resolution. Just for that alone, the Umidigi stands out from its competitors, but it doesn't stop there. I got a colour difference of 4.7E, it's certainly not perfect but you have to keep in mind that this is a robust phone sold for less than 150€. The price/quality ratio is therefore rather good.[b][b][b]Top 10 - ranking of the best screens by colorimetry 1. Poco X4 Gt dE = 0.6 2. Xiaomi Mi 10 Lite 5g dE = 0.73 3. Xiaomi Mi 10t Pro dE = 0.83 4. Redmi Note 11 dE = 0.91 5. Redmi Note 12 Pro dE = 0.97 6. Google Pixel 6a dE = 1.01 7. Google Pixel 5 dE = 1.11 8. Realme Gt dE = 1.17 9. Redmi Note 12 dE = 1.17 10. Xiaomi Mi 11 Lite dE = 1.19
Number of smartphones in the ranking:75 Position of this smartphone in the ranking:59/75
Note: the colorimetric difference is measured in dE. After three, the human eye will perceive a colorimetric difference, so the dE should be the lowest. The tests were all carried out with a colorimetric probe. [b]Brightness / Contrast[b]From the first use of this phone I noticed that the brightness of the screen was important and the test with my probe confirms this. I measured a brightness of 598 cd/m², this is one of the most powerful screens I have ever tested and as this phone is intended for outdoor use, such brightness will allow it to be used in full sunlight.[b][b]
Biometry
The Umidigi is equipped with a fingerprint reader on the left side of the phone, I had not yet tested a phone with this type of configuration. To be able to use it you need to be able to pass a finger from the right hand to the left of the phone, you need a large hand. I have the impression that this fingerprint reader was designed for left-handed people.[b][b]In absolute terms this reader works well but its accessibility is not very good.[b][b]
Operating system
[b][b][b]This phone runs pure Android 10, which means that Umidigi has not added any unwanted applications (bloatware) and the menus/functionalities are the same as those on other phones running Android 10 without overlay.[b][b]

I assigned a score of 1 to 10 for each test that determines the strengths and weaknesses of a product. I am using 0 for criteria that have not (yet) been tested. A score of 1 to 3 indicates poor performance (and yes, it does), a score of 4 to 6 indicates average performance, a score of 7 to 8 indicates good performance, and a score of 9 and 10 indicates exceptional performance. . The score is calculated based on my measurements and when there are no measurements, it is a subjective opinion based on my experience.
The scores are not static, they change over time because the performance of new products changes and this must be taken into account.

Test / Review conclusion
[b]When I bought my first rugged phone, I figured that my test was not going to interest anyone because the target audience was too small. I was surprised by the success of this test, so I continued to test this kind of TV but always with the feeling that there was something missing from these phones.[b][b]I tested other Umidigi phones before testing this model and there again I was still missing something. It was with this Umidigi Bison that the change finally came. It's the first rugged smartphone that has everything a normal phone can offer without any real constraint related to its ruggedness. Umidigi has also progressed by offering a complete phone for a very affordable price. In the end, this Umidigi Bison is the best rugged phone I have ever tested.[b][b]The Umidigi Bison has a much neater appearance than the other phones of this type that I have tested, it is aimed at a wider audience. Most of the usual weaknesses of Umidigi have also been fixed (e.g. network sensitivity or operating system bugs). [b][b]The format of the phone is still quite imposing, it takes some getting used to, I often pressed buttons by mistake because the placement is not always judicious. The screen occupies an interesting surface where Ulefone or Doogee had made many sacrifices. The battery is solid, the performances are sufficient, the sound with headphones is excellent, the sensitivity to the 4G network is good, the wifi speed is excellent. [b][b]Of course everything is not perfect yet but for a purchase price of 130€ you won't find many competitors. [b][b]Strengths[b]- good battery life (although it could be more efficient)[b]- very bright screen and good colorimetry[b]- sound with headphones[b]- 4G network sensitivity[b]- finish / solidity[b][b][b]Weaknesses[b]- photo/video processing[b]- wifi signal sensitivity[b]- energy-hungry screen[b]- loudspeaker sound [b]- button placement[b][b][b]Alternatives to this product[b][b]
