Yellowish screen dim

[VitekST]

Hello,
I have Xperia SP (C5303) with latest original firmware, 12.1.A.1.205.

Well, the problem is, very often the screen suddenly turns yellow and starts to dim. After few seconds, screen turns normal, and I can use it normally.

It's pretty annoying.

Can you help me?

Thanks,
VitekST

Mine does that also. Never found the cause.
