My Samsung Galaxy 3 Tab turns on but won’t let me type in my pass code and won’t do anything else. How do i fix it?
I agree with Hovsep, but you might want first to try letting the battery run out, then recharging and see if that works.
I think you need Factory Reset, As long as you have a Google account synced to your Samsung Galaxy Tab 3 , your contacts, calendar.... will be re-synced to Samsung Galaxy Tab 3 as long as you sign in with the same Google/Gmail account
but you can try to go to recovery mode and choose reboot, perhaps can fix your problem and let you to sign in.
1) Home button+Volume up button+Power On button.
2) You should see samsung logo, you can let go power on button
3) Keep holding the Home button+Volume up button until you see the Recover screen
4) Choose Reboot Now
