iPhone XR Screen Glitching
Recently, my phone started to glitch. The home "button" is swiping up by itself causing the windows to glitch or switch between apps making the phone unable to use at times without turning off the screen. The lower portion of the phone's screen is a bit cracked. I did put a tempered glass screen protector thinking it could help get dust out but it is still happening. The glitch also was happening before and after I updated my phone to iOS 15.
Besides buying a new phone, what can I do? Replacing the screen? Does it even have to do with anything related to the screen?
