Hello @tolugeorgeinfo, please were you able to fix your screen? I use a OnePlus 3T and currently have issues with my screen. There's an ink smear on the corner of the screen and its slowly spreading. I think it might be a digitizer issue but Im not very certain. Any suggestions please?
Thank you.

Hello Sir. I found your comments on a different thread on using less popular Android devices in Nigeria. I currently use a OnePlus 3T and have an issue with the screen.

I woke up this morning and noticed a little purple spot on the corner of the screen. Over the course of the day, the little purple spot has gotten a little larger; it's now purple with blue and is spreading.
The touch screen still works where the spot is so I'm not sure if the digitiser has gone bad or something?
I used my phone up to last night and there was no spot on the it. Please do you have any suggestions as to how I can fix this. Thank you
