Hi All, You may have seen this problem already in
1)Initially, when I unlock phone by pressing power button the display was changed to dim colour(mostly yellowish) and with horizontal lines displayed when the brightness is below 50%. After tried with multiple times pressing on power button the display came back to normal.
2) Next stage, it's not solved with power button. I have to keep my phone aside for some time to get back to normal display. It's been 15 to 20 min then.
3) Now, I would get normal display only in morning. Else, I need to keep my phone idle without touching for at least 4 to 5 hours. I've also changed screen power off time from 30 Sec to 10 Minutes. So that my screen wont turn off and I can keep the normal display. If I forgot to use or kept aside more than 10 min then my screen would go off and display would gone again and irritation starts with that discoloration problem..
4) If display changes to yellowish to reduce the horizontal lines problem I need to increase the brightness to 80 or 85% but this causing my phone with another problem "heating issue"
I am facing the same issue since about 4-5 months now. Its totally random.. any time of day screen would change color n show lines.. sometimes a litlle.. sometimes the discoloration is so bad its just impossible to use the phone and have to just flip close the cover n put it aside with hope of it being usable after 5-10 mins or after restart. And that doesnt always happen.
I am using the original samsung flip case and the phone has no physical damage of any kind.
Have searched a lot but not able to find any lasting solution. Hope samsung resolves this problem soon(!?).
Such major issue on one of its flagship phones lasting months without any solution or response from samsung is really unprofessional and careless.
