Mine seems OK in Android, but the big problem is the battery life, and the fact I can’t recharge it in Android or when powered off, only recharge in Windows…
Mine works similarly as Nick’s – terribly in Android.
But at least it could be charged in Android (and powered off), not just in Windows.
I wrote Teclast a message about Android stability to their Facebook page, but no reply from their side. Generally, they do not like to do any customer support at all…
Mine for the most part works well, had a few times I’ve had to restart to get it working well again. Battery life is much worse with android though and especially if playing games. I’ve got latest bios and an sd card formatted to NTFS
