No solution after all this time. I've send a report and got the answer to wait until the next patch rolls out. I can't use my phone outside for weeks because nothing is visible in the sun. Why there is no official rollback or fast fix?
Thank you for this. For me it helped only for some minutes. Even a factory reset didn't fix this problem with the brightness
I've got my update yesterday in Germany. Since then my mobile phone doesn't work properly.
