Hi,
I have an old Samsung galaxy Note 10.1 that has been a problem since day one.
I have turned it in for repair twise, but they could not find any problems.

The problems seems to me, like some sort of bad cable connection. Colors change and is not usable. If i twist or bend the tablet it sometimes goes back to normal..
Pictures shows how the colors change..


Any ideas, and can this problem be fixed?

Unfortunately that does seem to be a hardware issue, either with a bad connection or a bad display panel. Not sure why you can replicate it and repair centers can't, though...

Thank you for replying.
The problem does not come instant, sometimes i can use it for hours, and sometimes 5 minutes before colors change. So i think that the repair center havent seen the problem. This was years ago, so i just gave up.. But now im back at school, and it would be really handy for notes!

Have you tried using it on Safe Mode? Or doing a factory reset?

When this happens, does the tablet freeze or you can still use it, just see the weird colors? Also, if your finger doesn't work, the S-Pen might as the finger digitizer and the S-Pen circuitry are two separate things, and only the first is usually coupled with the display panel.

I have not tried safe mode, how do i find that?
The tablet does not freeze, i "can" use it, but the colors make things unreadable..

Here's how to boot up in safe mode.

If you can still use the tablet then it does sound a lot like a loose connector rather than software, but we'll see.
