Umidigi F2 Smartphone Review – 48 Megapixel in Affordable

At eye level? Thanks to a high-resolution camera, an additional wide-angle lens and a long-lasting battery, the Umdigi F2 wants to compete with other affordable mid-range smartphones. You will find out whether this is successful in the review.

Case, Equipment and Operation - Slow WLAN

Umidigi does not have really expensive smartphones on offer: the most expensive models are around 400 euros. The Umidigi F2, which we take a closer look at in this review, costs 250 euros on the internet, but still comes with a decent equipment: 128 GB UFS 2.1 memory, 6 GB RAM, dual SIM and its own microSD slot. NFC is also on board, but only older Bluetooth 4.2, but there is support for numerous LTE networks, which makes it possible to use it in many countries.

In our WiFi test with the reference router Linksys Nighthawk AX12, however, the smartphone cannot play out its WiFi 5 and only offers speeds on WiFi 4 level.

The case has a relatively simple design, with a glossy black or gradient back. The Umidigi phone looks a bit bulky and is also not a lightweight at 215 grams. However, it has a clean and stable finish, only pressure on the screen gets through to the liquid crystal.

The operation is precise and reactive, even the touchscreen surface gives no reason for criticism. On the right, there is a fingerprint sensor in the standby button, there is a minimal delay until it unlocks the smartphone, but overall this is not disturbing.

Pure Android 10 is pre-installed, the security patches are hopelessly outdated at the time of testing.

Cameras - Umidigi with High Resolution Cam

Recording front camera
Recording front camera

A 48 megapixel camera is currently also built into high-quality smartphones like the OnePlus 8 Pro, and the Umidigi F2 wants to get a bit of the hype. Now, of course, you can't expect a picture quality for 250 euro, which is equivalent to a mobile phone for almost 1,000 euro. But as our test of the Umidigi Power 3 has already shown, even the cheaper camera sensors can now take decent pictures.

The Umdigi F2 can also take sharp pictures with surprisingly many details under good light, although the 48 megapixels are only used if desired, usually 4 pixels are combined into one to achieve more light output. This way the pictures also appear strongly exposed, sometimes a little too bright, so that colors turn pale. Pixel artefacts in the sky in the surrounding image also show that you are not dealing with one of the highest quality sensors. Under low light the brightening is pleasing, but the detail sharpness could be higher here. 

There is a wide-angle lens as well as a telephoto lens, but both have to be chosen carefully, so you can't switch between them automatically via zoom. 

Videos can only be recorded in Full HD and at 30 fps, so the quality is decent here. 

The front camera has a lush 32 megapixels, and takes well-lit and detailed pictures.

Display - Strong Blue Cast

Sub-pixel array
Sub-pixel array

The screen can become reasonably bright at 512 cd/m² on average. It has a slightly extended Full HD resolution, which is standard in this price range. The contrast is also on par with the rest of the range, but it's not really good, as colors look a bit pale on the display. The Samsung Galaxy A51 with AMOLED display has a clear advantage here.

We use the CalMAN software and special measuring devices to determine the accuracy of the color display and here, the Umidigi F2 with a strong blue cast and high deviations won't win any prizes. On the other hand, we do not notice any PWM flickering, which is a blessing for sensitive people.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
24 ms ... rise ↗ and fall ↘ combined↗ 9 ms rise
↘ 13 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 36 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
40 ms ... rise ↗ and fall ↘ combined↗ 21 ms rise
↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (38.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17531 (minimum: 5 - maximum: 2500000) Hz was measured.

Performance, Emissions and Battery Life - Umdigi F2 as Continuous Operation

MediaTek's Helio P70 is a midrange processor that is well equipped for everyday tasks. But other smartphones at this price level offer even more power, like the Huawei P40 Lite. The memory is reasonably fast for its price range, but here too, things are even faster, as the Huawei smartphone proves. The microSD reader can't recognize our Toshiba Exceria Pro M501 as the reference microSD, and only slow transfer rates are possible with the slower Hama card.

The Umidigi F2 can get quite warm, which can become unpleasant at a maximum of 44°C and longer skin contact. The loudspeaker on the bottom edge is reasonably loud and sounds acceptable, highs aren't overemphasized too much and the mids are quite present.

In terms of battery life, there are definitely very good 17:58 hours in our WLAN test, but a very high capacity battery is also built into the device for this. Thus, the distance to the clearly lighter Huawei P40 Lite isn't huge. It's probably enough for 3 days without recharging in moderate use, but those who leave their smartphone unused for a longer time will probably get by even longer. The smartphone is fully recharged in just under 2 hours thanks to quick charging.

Verdict – Good Camera Phone with Weak Points

In review: Umidigi F2.
In review: Umidigi F2.

The Umidigi F2 has a decent camera with a wide angle option. It's by no means on par with top-of-the-range smartphones, but overall it takes decent pictures.

You should also take into account the manufacturer's sloppy handling of security patches and the warranty on paper, which is only complicated to honour in many countries due to the possible need to ship the camera to China. Also the high warming can be a problem. In addition, the screen has a good resolution, but falsifies colours and is a little pale in appearance. The WLAN also falls short of expectations.

The flexible camera system with decent pictures is convincing for the price, but you have to put up with some weak points on the Umidigi F2.

All in all, the Umidigi F2 is a smartphone that should be looked at by those for whom a flexible camera equipped with solid image quality is more important than anything else. The battery life is also good, but you should not rely on the outdated security patches.

Editor of the original article: Florian Schmitt - Managing Editor Mobile
When I was 12, the first computer came into the house and immediately I started tinkering around, taking it apart, getting new parts and replacing them - after all, there always had to be enough power for the current games. When I came to Notebookcheck in 2009, I was passionate about testing gaming notebooks. Since 2012, my attention has been focused on smartphones, tablets and future technologies.
