Uneven screen brightness

[Daniel Francisco1]

Greetings everyone!

I've been using my Lumia 735 since May 2015 and I think the phone is simply awesome.

It has, however, what I think to be a defect: the screen/display brightness is not evenly distributed. It shows a colour gradient from the top tight corner to the bottom left corner (pictures below). The top right corner starts with a slightly purple tint which gradually becomes the (supposed) original grey background for the alarm settings in this case.

I've searched the forums and found that some Lumias 930 have a similar issue.

Is this a software issue that can be solved with a specific update?

Thank you.

Try fiddling Color profiles and are you sure, you set the brightness to lowest and then toggle auto adjust. That grey navigation bar is to protect the screen from suffering a burn-in: A normal behaviour observed in AMOLEDs.

Thank you for the reply.

I have already done that. The grey navigation bar gets affected by the same issue since the pixels are not being illuminating evenly so everything on the screen will have an uneven brightness.

Just now i observed it too. Maybe some kind of protection against burn-in. That is, alternating use of each and every pixel to get even usage pattern. I can't speculate too much, you could take it with grain of salt. More like, wear levelling alg. on an SSD.

"More like, wear levelling alg. on an SSD." Can you explain this last sentence? I did not understand it.

I can already see Windows navigation keys(icons) burned in on my AMOLED, it is visible on a bright colour screen.

I always hide nav bar when not in use, BTW, its just half a year old.

Thank you for the replies. I tried upgrading to Windows 10 hoping the problem would go away but it didn't. It's a hardware problem definitely.
