Do you know how to reverse X and Y axis for my touchscreen ?

Answer 1

I know that this post is old, but this was a problem I encountered recently while I swapped the broken touchscreen from my Android tablet. The replacement was a poorly manufactured p.o.c.s... Anyway, after I plugged it in, the xy was swapped first, then I turned the connector over and it was just an x-axis problem. I knew that if I flipped the glass over, it would fix it, but that would make the connector too far away from the port on the motherboard. So I just plugged it in, and went to the settings of the tablet, and calibrated the touchscreen from the settings menu. Done. That's it. SOLUTION: Just go to the settings option in the menu and find the "Touchscreen Calibration" option and calibrate it again. This should fix it :) Or just flip connector around and try again :) The reason I posted this is to help others who might have this problem :)
