It often blinks and natural screen colours show up, other times prints / traces of recent app(s) are visible in the background, even home screen wallpaper and keyboard are visible in the background of any app / hub. Sometimes it all gets high blurr and makes it impossible to recognise anything.

I've tried hard resetting but it didn't work. Even on the restarting screen behind the blackberry name and logo, the same shadows / traces / prints are visible. Looking for a solution other than factory resetting / wiping out entire data.

Want to know if the damage is permanent or temporary / fixable. And what caused it.

In the beginning it used to go away after pressing the power key to lock the keypad and the by waking it up by sliding.
Now sometimes it acts normal when battery saving mode is off, and screen brightness is full.
Only unusual thing I did before it all started was setting an alarm with vibration mode on.

And a reboot does not fix it?

How old is the Z10? I guess it might be a hardware failure due to age. Any new apps added recently?

You could try reloading the OS using an autoloader?

Good luck.

Also you could try asking in the Z10 specific forum.

Nope !

It's 3 years old.

No new apps.

Re loading OS, would it compromise the data?

Thank you !
