I have entered the Test Touch Config Menu and can see the numbers. However, I cant seem to change them? Pressing in the box does not open the numeric keypad.
My touch on F480 is not working ;S only those 3 buttons down are working
nothing else! How can i fix it?
sorry, but there’s one more menu you have to enter after going to ‘Test-cases’ -> ‘TS-GWES’! In there you’ll find ‘Test Touch Config’. There you should be able to change each value! Tested it on my own phone in that moment…
