My phone is glitching if I higher my brightness to max

So, I brought this phone second hand. I normally have my phone’s brightness low because I like saving the phone’s battery, but I noticed whenever I put the brightness all the way up the phone would start glitching but when I turned it back down it stopped. Does anyone know what’s up and how I can fix it? :)

Answer this question I have this problem too

Is this a good question?

Did you wipe the phone or reset it to factory defaults before you set it up for use?

There could be an issue with the backlight IC(integrated circuit or chip) or coil on the logic board. These are commonly replaced parts for issues with backlight or brightness.

You can also try a few things in the phone settings to help. This guide is for an iPhone 6 and not the 6s but it should be relevant enough to help. https://www.igeeksblog.com/how-to-fix-di...
