After managing to get back to original firmware I have a problem with screen calibration.
When I start tablet it opens with the screen calibration screen. After clicking on the cross hairs I get a message saying "Failed to calibrate Please try again or slide power switch to the left"
by sliding switch to the left I can use the tablet but the touch is way out. For example on the keyboard I can not change to numbers and if I want a letter a I have to click on the ?123 bottom left. Other keys may select normally or I have to click just below the letter.
I have re-installed the firmware twice and also done a factory reset with no improvement.
Thanks in advance
