I've just got the Bold 9000 off ebay.

When I lock the phone and the screen goes into "standby" and then I reactivate the screen, it comes up white. If I scroll around, the parts highlighted go OK. If I unlock the phone the screen comes back to life.

Sometimes it goes a grey sort of crackled screen instead of white. I assume the screen is OK since as soon as I unlock or go to the menu everything shows up OK. Any idea what the issue could be?

I upgraded the OS from 4.5 to 5 this morning but the issue hasn't gone away.

Thought I'd upload pics to try and explain better.

The first one is when I press a button from the lock. It then goes crackled.

The third one is when I move the trackball around

The fourth is when I unlock the phone

This happens when I dont have the phone locked and the screen comes from stand by. But when I press a button the whole screen comes back to life
