Lenovo Tab M7 Tablet Review: The Kindle killer with Android Go

Extremely cheap. With the second generation of the Tab M7, Lenovo brings a very low-priced tablet to the market, which, despite its weak hardware, cuts a very fine figure. Thanks to Android Go, there is no unnecessary bloatware, and for only 79 Euros (~$88), the tablet delivers almost everything you can expect from such a device.

Lenovo Tab M7 Tablet

Lenovo is primarily known for its numerous notebooks. This year we reviewed two Lenovo tablets (Tab M10 and Tab P10). They had very good build quality but offered poor system performance. We do not expect the Tab M7 to have great system performance either, because it comes with Android Go and is primarily designed for simple applications

For only 79 Euros (~$88), buyers get a 7-inch tablet with MediaTek’s MT8321 SoC, an ARM Mali-400 MP2 GPU, 1 GB of RAM and 16 GB of internal eMMC flash storage. With this hardware configuration, the Lenovo tablet has to compete against other similarly priced slates. For this review, we selected a number of comparable devices from our database.

Case - Cheap tablet with small bezels

The Lenovo Tab M7 has a robust metal chassis and comes in three colour schemes. The build quality is very good and there are no defects. The buttons on the right side of the device sit firmly in their cutouts and the microSD card tray does not wobble in its slot. While the back is very susceptible to fingerprints, the front is dominated by the touchscreen. The bezels are not super-small, but they are smaller than those of the Amazon Fire 7. The weight, at 235 grams, is also lower.

Software - Tablet from Lenovo with Android Go

The Lenovo Tab M7 runs the Go version of Android 9. The security patches were last updated on October 5, 2019. Thanks to Android Go, the system feels responsive even on low-spec hardware. There are no preinstalled third-party applications. While multi-tasking, you can run into occasional stutters. In this case, the Lenovo Vantage application can come in handy, because it allows users to free up RAM and close unused applications.

The Camera2 API is only supported in a “limited” fashion, and because there is no support for Widevine L1 DRM, it is impossible to stream Full HD content from Netflix, Amazon Prime or Maxdome.

We use the GPS Test application to examine how well the Lenovo Tab M7 does when it comes to geolocation. The Lenovo tablet supports the following geolocation systems: GPS and SBAS. Outdoors, our review device has a margin of error of up to three metres. Indoors, the Tab M7 fails to connect to the satellites.

In order to determine how accurate our review device is when it comes to geolocation, we take it with us on a bike ride. On this bike ride we are also accompanied by the professional navigator Garmin Edge 500. The Tab M7 recorded the route that we took quite accurately. The tablet only had trouble keeping up with the Garmin Edge 500 at sharp turns, which is where the larger deviations come from.

Cameras - Not fit even for snapshots

The Lenovo Tab M7 features a 2 MP main camera and a 2 MP front-facing camera. Both cameras produce very poor shots. However, the front-facing camera produces somewhat duller colours than the rear camera. The panoramic shots appear blurry, and the finer structures are barely discernible. All in all, the images are very grainy. In the camera settings, users can adjust the ISO, white balance and the exposure. There is also the so-called “Scene mode”.

The main camera takes very blurry photos in low-light environments. Because the images are so grainy, the structures and details are hard to discern. Surfaces and objects in the background also look grainy. Under poor lighting conditions, the image quality becomes even worse. Objects are hard to recognise and the whole image is very noisy. There is also a “beauty mode”, which allows users to apply various colour filters.

The video shot with the main camera offers a similar level of quality as the photos. Motion appears somewhat blurry, but stabilisation works well when the camera is not shaking too much. Video can be recorded in either 480p or 720p. The Lenovo tablet does not offer a high frame-rate mode or anything like that.

We use the ColorChecker Passport tool to assess the colour accuracy of the Tab M7’s camera. Most of the colours appear too bright. Yellow tones are reproduced especially poorly. Under an illuminance level of 1 lux, our colour chart is no longer recognisable. 

Under controlled lighting conditions, the Tab M7 takes better shots of our test chart. However, the images are still quite grainy. Fine details and structures are also recognisable, but the sharpness is lower at the edges of the image. Moreover, the bottom corners of the image appear washed-out. Under an illuminance level of 1 lux, our test chart is no longer recognisable.

Accessories and Warranty - 24 months for Lenovo tablets

The box contains a USB charger with a microUSB cable and a SIM card removal tool. Lenovo does not offer any additional accessories for the Tab M7.

The Lenovo slate comes with a 24-month warranty. 

Input Devices & Handling - Good touchscreen in the Tab M7

Google’s GBoard is used as the default virtual keyboard, which is why typing longer sentences in portrait mode is quite easy. The touchscreen is very responsive. When it comes to larger drag-and-drop gestures, the touchscreen puts up too much resistance. The motion sensor recognises when the device is rotated very fast.

You can use a PIN code, a pattern or face recognition to unlock the device. Face recognition works well under good lighting conditions.

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 17520 (minimum: 5 - maximum: 2500000) Hz was measured.

The Tab M7 has a very good contrast ratio and a somewhat elevated black value of 0.25 cd/m². This is why the Lenovo tablet takes second place in our comparison chart and is only beaten by the Amazon Fire 7. In the APL50 test, the black value (0.45 cd/m²) is much worse.


The CalMAN analysis reveals that the colours appear too cold. You can choose between three colour profiles (normal, warm, and cold) or you can use a slider to adjust the colours to your liking. The Night Light can be configured to turn on at a specific time, which makes the colours appear much warmer.

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
34.8 ms ... rise ↗ and fall ↘ combined↗ 17.6 ms rise
↘ 17.2 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 240 (maximum) ms. » 90 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey

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. » 84 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.7 ms).

Outdoors, the Lenovo tablet is usable in the shade. While the screen content is easy to recognise when looking at the display straight on, the reflections start to crop up when looking at the screen at an angle.

Performance - Only fit for simple applications

The Lenovo Tab M7 features the MediaTek MT8321, which is a very simple SoC. Due to 1 GB of RAM, the results in the benchmarks are not very good. The ARM Mali-400 MP2 graphics unit is only fit for non-demanding applications. 

The Tab M7 does not do very well in the benchmarks. It takes last place in almost every category. Some benchmarks, such as PCMark 2.0, complete successfully but give out a score of 0 points. Especially demanding graphics benchmarks cannot be performed, because some graphics APIs are not supported.

Our review device has 16 GB of eMMC flash storage. It achieves slightly worse read and write speeds than most other devices with 16 GB of eMMC memory.

The SD card reader of the Lenovo Tab M7 delivers very poor write and read rates with our reference-grade SD card Toshiba Exceria Pro M501 and therefore performs worse than all devices that we included in this review.

Gaming - Casual games are playable

The ARM Mali-400 MP2 is ill-suited for gaming. Casual games work fine, but more-demanding titles are plagued by stuttering. Some games do not work at all, because not all graphics APIs are supported.

In Arena of Valor, the menu felt very laggy and the game itself did not run smoothly. Asphalt 9: Legends crashed as soon as we launched it. Simpler games such as Temple Run 2 ran smoothly.

The speaker of the Tab M7 offers a high volume with the exaggerated highs. Media content sounds tinny, and the sound stage is not very wide. We recommend using external speakers or headphones. The headphones can be connected to the Lenovo slate via the 3.5-mm audio jack.

Battery Life

In our practically oriented Wi-Fi test, the Tab M7 had a battery runtime of 6 h 42 m, which means that the Amazon Fire 7 lasted longer in this test, even though it has a smaller battery. Other tablets, such as the Alldocube M8, managed to outlast the Tab M7 only by a very small margin, despite the fact that they have much bigger batteries.

The Lenovo tablet does not come with a fast-charger, which is why it takes about 4 h 30 m to fully charge.

The Lenovo Tab M7 is no powerhouse. The benchmark results are not very good, and the Wi-Fi as well as the storage could have been faster. When it comes to battery life, a device with such a low power draw could have squeezed more out of its 3500-mAh battery.  

The Lenovo Tab M7 is an option for anyone who is looking for a simple tablet with a stock Android experience.

At the end of the day, we are very fond of the Tab M7. The build quality is solid, and unlike the Fire 7 from Amazon it does not come with thick, annoying screen bezels. For only 79 Euros (~$88), the stock version of Android Go is a very good alternative to Amazon’s Fire OS, which features many proprietary Amazon applications. Those who are looking for a cheap and small tablet, which will be used primarily for surfing the Internet and occasionally watching videos, the Lenovo Tab M7 represents a comparatively high-quality device with a very reasonable price tag.

Editor of the original article: Mike Wobker - Editor
I made my first IT walking attempts on a 386 with 4 MB of RAM. After that followed various PCs and notebooks, which I looked after and repaired in my circle of friends and acquaintances. After an apprenticeship as a telecommunications systems engineer and several years of professional experience, I graduated with a bachelor's degree in industrial engineering. Today I live out my fascination for IT, technology and mobile devices by writing test reports. In my free time I like to devote myself to vegan cooking and spend time with my family, which includes a whole range of animal roommates.
