I own a tablet 7 "(Luftco A oneX). [It is the same like Tronsmart PS7]
Now I have searched for hours and days after a solution to my problem.
Here is a Video of the Problem:
My problem is that when I function ore pushed up, down, left or right scroll with your finger all, but if I want to scroll quickly and easily wipe in one direction and the finger going let that tablet scrolls briefly in the right direction and then scrolls exactly in the wrong direction, for example, the menu or the browser.
I've tried all the firmware and everywhere the same problem.
Sorry for my English.... (Google translate)
For your help I am very grateful
