Hittade följande nedan som skulle vara realaterat till "Screen Shot" app. Men jag har avinstallerat den och samma elände fortsätter ang. screenen.
When you see the white stripes wait some minute, just let phone to Boot up...
You dont see that, but Phone doing the boot don't carry about stripes
[Sometimes phone boot normaly, but touch screen not working properly..] - (That's ok...)
Then Press Home and the same time Sleep/Wake Buttons
Wait until screen goes black (Quick release buttons) then wait about 3 seconds and press Power On button...
