Teclast T20 Review

Just last month on the 28th, Teclast released the third product in the “JiangXin” series of tablets: the Teclast T20, which was officially released on September 3.

Like the previously released T10 and T8, the “JiangXin” series is the highest-end Android tablet product from Teclast, so design, materials, configuration, and workmanship represent the pinnacle of Chinese brands. And the most distinctive feature is that the Teclast T20 is the only tablet product that uses MediaTek X27 processor, which is far from the mainstream X20 product.

Design

The packaging design of the Teclast T20 is quite simple. In addition to the brand logo, there is only one “JiangXin” logo for the hot stamping process. In terms of surface material, it is not a simple white paper. Under the close look, there are fine lines on the surface, which is characterized by high-end texture.

However, compared to other mainstream 10.1-inch panels, the Teclast T20’s frame, thickness and other aspects are ahead of other competing products.

Teclast T20 uses a metal body design, through the fine sandblasting process to create a better touch, making the T20 feel as good as the Apple iPad.

The Teclast T20 upgrade uses a more cutting-edge Type-C interface, which has better power supply and faster data transfer capability than the traditional Micro-USB, and supports the trendy Type-C headset. Of course, the T20 did not “discard” the traditional 3.5mm headset interface.

On the T10, the highly acclaimed Sweet Sound system has not only been retained in the T20, but also more comprehensively adjusted and optimized the frequency response curve characteristics of the speaker, which further enhances the performance of high and low frequencies, making the subjective listening of the T20 externally more Excellent, comparable to Huawei’s tablet products with Harman Kardon certification.

For the first time, the Teclast “JiangXin” series tablet has increased the front camera of the tablet to 13 million pixels, and added support for the beauty function. On the T20, Samsung’s 13 megapixel front camera is well extended, and F/2.0 large aperture, more than 80° over the viewing angle is retained; and the rear camera upgraded to 13 million pixels, from Samsung’s sensor.

As can be seen in the above picture, there is a black hole next to the front camera, which is just an ambient light sensor for sensing the ambient brightness and is used for automatic adjustment of the screen brightness. It allows the tablet to have a good display in different environments.

Performance

The mainstream 10-core tablet uses the X20 (MT6797) processor from MediaTek, which has two A72 and eight A53 cores, of which the high-performance A72 core has a maximum operating frequency of 2.1GHz; however, the Teclast T20 uses X27 (MT6797T), not only its A72 core frequency has been increased to 2.6GHz, the other A53 core frequency has also increased to 2.0GHz, the performance has increased by more than 30% compared to X20.

Because the high-performance A72 core has an ultra-high 2.6GHz frequency, the T20 has a high score of 1714 in the Geekbench 4 test score, which has surpassed the Qualcomm Snapdragon 821 processor level. The single-core performance of Kirin 970 and Snapdragon 835 is just around 1900. It can be seen that the single-core performance of X27 is comparable to the mainstream flagship processor.

Antutu test is a comprehensive machine performance test, Teclast T20 final score of 109,329 points, compared with other products using X20 only about 90,000 points, an increase of about 20%; the results are in the mainstream The level of the mobile phone.

The Antutu test comes with an HTML5 test project, which is highly relevant in browser performance. Although Antutu recommends the use of the Cheetah browser, the T20 comes with a Chrome browser, so I chose the factory browser as the evaluation standard, and the results can be used as a reference.

Display

The Teclast T20 has a 10.1-inch display 2.5k from Sharp , a resolution of 2560 x 1600 adduced. The pixel density of 298ppi is only just below the Retina value. Individual pixels are nowhere to be seen . The 10-Point Multitouch Screen recognizes at the same time … well guess, exactly 10 touches at the same time. This also relatively precise. In some situations, however, one notices smaller delays. Especially with faster movements, commands are sometimes not recognized.

The IPS panel offers a natural color scheme and good contrast on average.The brightness average is 334 in the upper display area, 335 in the middle and 301lux in the lower area of ​​the screen . That is relatively little for an IPS display. In direct sunlight, or when using the tablet in the wild, it can therefore cause problems in readability. When using in your own four walls, but there is no problem. In addition, the viewing angle stability is, as used by IPS displays, very good, only the display reflects very strong. When used outside, you can thus sometimes no longer recognize anything. Color reproduction, as usual with MediaTek SoCs, can be adapted according to your own needs using MiraVision.

The T20 is only operated with the on-screen buttons. Unfortunately, the device does not have a brightness sensor or even a notification LED on board. Thus, the brightness must be set manually. A night mode, which protects the eyes in the evening and night hours, is unfortunately also missing. The tablet is provided by the manufacturer with a screen protector as standard. This is certainly useful, because no scratch-resistant gorilla glass was used. At least a screen protector is mounted as standard.

System

On the T20 is a clean version of Android 7.1.1. pre-installed, which is also free from any bloat or malware. Only the program known by Mediatek Dura Speed ​​is available as add-on software to control background processes. All Google Apps are also implemented as standard . The system seems to be very mature and works flawlessly. Crashes did not occur during the 2-week trial period. Updates would be conveniently installed via OTA, but this is unlikely to happen given the price.

Sure, a tablet of this size is ideal for watching movies, or even to Netflix and Co. to look. However, one can not stream that in the T20 in HD quality, which is a major shortcoming. Unfortunately, the tablet only has the Widevine Security Level 3. As a result, you can not watch the streams from Amazon and Netflix in HD. However, the device shares this fate with many other Android representatives, because the certification is especially too time-consuming or too time-consuming for smaller manufacturers.

Stock Android is nice on the one hand, because it’s just not overloaded with features. Here one limits oneself exclusively on the essentials. No system manager, no useful features and certainly no themes. Yes, that is almost boring. If one of the Google Launcher does not appeal, after all, can easily download another from the Play Store and use as a standard. It is also possible to change the font as required. In Font Manager you can fix download his desired font and use directly.

What is always advantageous in a display of this size is the ability to vary both font and display size as desired. So surfing and rummaging in the net is really fun. If you set the font and display to the lowest level, by the way, the 3 Android Home buttons are shared. The Back and Home buttons slip on the left side, while the square icon moves to the right side. When using with two hands that is quite a nice feature.

Dual SIM Card

The China smartphones probably serve as a model for the Teclast T20. Like most of you, the tablet has a Dual Sim feature . Both slots support parallel operation in 4G. Thanks to a separate slot for the memory card, no sim slot has to make more storage space.

The following bands are supported:

  • 1 (2100 MHz)
  • 2 (1900 MHz)
  • 3 (1800 MHz)
  • 5 (850 MHz)
  • 8 (900 MHz)
  • 38 (2600 MHz)
  • 39 (1900 MHz)
  • 40 (2300 MHz)
  • 41 (2500 MHz)

Surfing in LTE speed with the shortwave 800 Mhz band 20 is unfortunately not supported.Surfing with the Teclast is quite fun. We could not find reception problems. If you do not mind making calls in public via a loudspeaker, or if someone is not politely asked by your fellow human beings to refrain from telephoning, you can also happily chat with the M20. Due to lack of earpiece but that’s just about handsfree. If you have a headset with you, you can also connect it to make a call. Even without headphones, the person at the end of the line is clearly understood, although the volume could have been a bit higher. Due to the size of the tablet, navigation in the car is a bit difficult.

Summary

The biggest feature of the Teclast T20 tablet is its color and sound effects, which makes it perfect for all kinds of audio and video experience. In addition, it is based on a 10-core processor, 4GB memory, Android 7.1 system, etc. Its performance is not bad at all. A variety of popular games are more immersive and refreshing. For the 10.1-inch screen size Teclast T20, its use can be better than smart devices such as mobile phones in more scenarios, especially to support SIM cards, so that a tablet that can talk can make your smart life Feel more colorful.
