Phone acting weird

[vikingator]

Hey,

Since yesterday my phone is going crazy. It does the following things:

When i push the screen lock button i see my protetction on the screen for 1 second and then it goes black. Also sometimes the screen turns into a white and colorful show when i'm using my phone. Also it sometimes the screen starts to shake in several forms.

Someone know a solution to this problem?
