Are the pixels dead? Or just not working while calculating (working when graphs are drawn).


@ulees Everything in the calculator works, i just have a big black half circle sticking out from the side of the screen that’s blocking numbers


@summerrose Is it dead pixels or something between the glas?


@ulees i actually don’t know, what would be the solutions for both problems?


@summerrose There is one solution for both problems and it's warranty. If you don't have it then there isn't solution for dead pixels problem. If it's something in the between of screens you can teardown your device and try to remove it. I doubt that is the last one.

If this helped please let me know so i type a full disclosure in answers tab so people can find it easier .

Soluzione Prescelta


so me and OP of this post resolved the issue in the comments so if you don't mind reading all that.

If you are a little bit lazy just read the last two it contains it all.
