Sharp supplied the display panel, accordingly it promises the high quality. A big update over the predecessor (Teclast T10) is a 4G / LTE connection with support for many network bands. Other features include a large 8100mAh battery accompanied with quick charging 9V via USB Type-C port.


Additionally, it comes with a fingerprint reader on the rear panel, Bluetooth 4.1 version, dual-band WiFi, 3.5mm audio jack and Android 7.0 Nougat. The Helio X27 SoC is accompanied by 4GB of RAM and 64GB of internal memory. Due to it, users can enjoy fluid and fast performance of the tablet.

Teclast T20: Design and Appearance of the 4G Tablet

Teclast chose the right path, getting all their screens from a reputable brand like SHARP, which are considered the best on the market alongside those from Samsung. Previous models Master T10 and M20 had the same chic 2.5K screen. There is a newly minted X27 processor. The memory is not very dense – 4\64 GB, but for Android, this is quite enough. Also, there is a separate slot for the SD card too. By synthetic tests, the performance gain is about 30% compared to X23. The graphics are the same on all three models (Mali T880).

The appearance of the Teclast T20 is very eye-catching. Its simplicity gives the tablet a luxurious look. The powerful tablet comes in a white small box.
