I’ve just uploaded the Android review video of the Teclast X80 Plus (Below) Android does perform well on the little tablet and the speaker sounds a little louder than in Windows. But it’s still no way near as loud as it should be. My review video below demonstrates just how the ROM is, benchmarks and gaming. Battery life is still quite poor, 3 1/2 to 4 hours battery life. Maybe more in flight mode.
Note it was recorded as 1280 x 800 60fps, but upscaled to 1080p. Recorded on an external Elgato capture card. Just a straight mirror, so how you see it in the video is just how it ran for me on the tablet.
