Nokia T20 Tablet review - Pad with LTE lasts forever

Tablet with Finnish finesse? The Nokia T20 is inexpensive, available with LTE on request, and looks good. Thus, it would be ideal for home schooling, video conferencing or just everyday life at home. But is the first attempt at a Nokia tablet a success? Or should we rather look at more established manufacturers?

Case and equipment - Metal and LTE

There's life in the old dog yet: While Samsung and Apple divided the tablet market among themselves, it became less and less interesting for other manufacturers due to the long lifespan of the devices. But in times of home offices, home schooling and video conferencing, tablets are experiencing an unexpected revival. Nokia is now also launching its first tablet in a long time, the T20.

The Nokia T20 has a metal case in blue for under 300 Euro (~$341). The chassis is well protected against dust and splash water according to IP52, but not completely waterproof. The tablet is stable, but can still be twisted and pressure on the screen is visible as image distortions in the liquid crystal. Overall, the T20 offers class-leading stability, but cannot stand out positively. The weight is also comparable with similarly priced tablets.

There is a WiFi and an LTE variant of the tablet and two storage options:

  • Nokia T20 WiFi - 3 GB RAM / 32 GB mass storage: 209 Euros (~$238, only available from Nokia directly in the online store at the time of testing, but not in stock)
  • Nokia T20 WiFi - 4 GB RAM / 64 GB mass storage: 239 Euro (~$272)
  • Nokia T20 WiFi/LTE - 4 GB RAM / 64 GB mass storage: 269 Euro (~$306)

Audio can be output via a 3.5 mm port or Bluetooth 5.0.

Software, communication and operation - Update promises and DRM problems

Nokia relies on quite pure Android 11 and promises 2 years of operating system and 3 years of security updates for its tablet. Corporate customers even get 4 years of updates as an option. However, this information is valid from the tablet's release and not from the time of purchase. Incomprehensible: The Nokia T20 only comes with a Widevine L3 certification, so it cannot play HD content on streaming portals.

Wi-Fi 5 is installed, but Nokia's tablet is a bit slower than comparable Android tablets. The speed is suitable for everyday use in our test with the reference router Netgear Nighthawk AX12, but you can get even more speed elsewhere.

There is no fingerprint sensor, but you can use facial recognition to unlock the tablet.

Cameras - Few details and one LED flash

Recording front camera
Recording front camera

Nokia installs an 8-megapixel camera on the back and even provides an LED flash, which is not common for all tablets in this price range. The photos are OK as snapshots, but will not satisfy demanding photographers: The exposure strength is low, large areas look unclean and generally the image content is not really sharp in detail. In very low light in the lab, the outlines of the image content are just visible.

Videos can be recorded with 1,920 x 1,080 pixels, but the autofocus takes a long time to focus correctly and the colors look very dull.

There is a 5-megapixel lens at the front, which takes somewhat blurry selfies.

Display - Blue cast and good contrast

Subpixel recording
Subpixel recording

The display of Nokia's T20 corresponds to the class standard in terms of technology and resolution: It is an IPS display with 2000 x 1200 pixels. It cannot quite keep up with comparable devices in terms of brightness.

The color reproduction suffers from a heavy blue cast in the factory settings, but you can manually adjust the white balance in the settings. The low black value and the resulting decent contrast ratio are pleasing.

We noticed flickering at low brightness, but with such a high frequency that even very sensitive people should not notice it.

Display Response Times

ℹ
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
44 ms ... rise ↗ and fall ↘ combined↗ 23 ms rise
↘ 21 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 98 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21.5 ms).
   ↔    Response Time 50% Grey to 80% Grey
58 ms ... rise ↗ and fall ↘ combined↗ 25 ms rise
↘ 33 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 93 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (33.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ
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 detected 3846000 Hz ≤ 10 % brightness setting

The display backlight flickers at 3846000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 10 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 3846000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

Performance, emissions and battery life - Lame memory and good sound

With the Unisoc Tiger T610 Nokia's T20 has an unusual SoC, but it can still place itself on the class level in many benchmarks. Nokia's tablet does not break any speed records in everyday use, but it cuts a decent figure. However, the installed eMMC storage is now noticeably outdated and slow.

Even under prolonged load, the large casing can be cooled without any problems, so you do not feel any heating up.

Nokia's T20 only comes with stereo speakers, the realme Pad for example, provides even more powerful sound with four speakers. However, Nokia's T20 sounds quite clear and the trebles do not distort even at high volumes. Qualcomm's aptX HD for Bluetooth audio is on board, but the newer aptX adaptive code is not.

Nokia does not do things by halves concerning the battery and installs a massive battery with 8,200 mAh. Nokia's T20 lasted 17:23 hours in our WLAN test and left the competition behind. Thus, two days of use without charging should be possible without any problems. The tablet needs to be plugged in even less often when used sparingly.

However, you should allow for some time if it needs charging since only a 10-watt power supply is included and the tablet does not support fast charging. You can wait for 3 hours or longer until the tablet is full again.

Verdict - Not for streaming freaks

In review: Nokia T20. Test device provided by Nokia Germany.
In review: Nokia T20. Test device provided by Nokia Germany.

Nokia's T20 is the company's (re-)entry into the tablet market. The chic metal casing with IP52 certification and the large battery are the highlights, but the unusual SoC also performs well overall.

The speaker sound is acceptable, there is at least a few years of security with the update promise, and the tablet is even available with LTE on request.

However, some points might annoy potential buyers: There is no Widevine L1 certification, so streaming content, for example via Netflix, can only be viewed in 480p. In addition, there is the slow loading speed and the lame memory.

The buyer should also be aware that one cannot expect too much from a tablet camera in this price range. At least there is an LED flash on the back.

Nokia's T20 is a successful mid-range tablet, but it is only suitable for entertainment fans to a limited extent.

Thus, there are definitely reasons to look at the competition: You won't get longer runtimes anywhere. The Lenovo Tab P11 has 4 speakers with a powerful sound and fast WLAN. Amazon's Fire HD 10 Plus you have to live with the limited software. The realme Pad is an interesting newcomer, but it is not yet clear whether the LTE version will be available worldwide.

Price and availability

The Nokia T20 is available in all variants directly from the manufacturer. However, many Internet retailers now also offer the tablet with 4 GB of RAM and 64 GB of storage as well as WiFi or LTE. The prices have even dropped slightly at the time of testing.

For example, the tablet is available at our partners amazon.de, notebooksbilliger.de or Cyberport.
