Display issues with windows 10 in my Lumia 630

[Paul Evins]

I have installed windows 10 technical preview for phones, as bf it was not than a month now with this buggy software, I don't know how, but the display brightness profiles are not working, the phone is set to always high brightness, and the right hand top corner of the display gone slightly Black, and the phone is excessively hearing in that part, I don't know whether its a software issue or the display got damaged by this buggy software PLEASE HELP ME GUYS.

Windows 10 doesn't have finished brightness profile. Try the action center toggle.

Also, that sounds like a legit broken display, not a software problem.

Downgrade to Windows Phone 8.1 again and see if the problem presists. If this is causes by Win 10, then leave appropriate feedback in the feedback app.
