I have been experiencing since a while a low-resolution screen issue on my
iPhone SE, it comes and goes but now it is becoming worse, I see thin lines on the screen, no sharpness at all.
Tried to restart many times my phone, to reset settings and to update it to the latest iOS version without success.
Not sure if it is software or hardware issue.
iPhone 6, iOS 12
We, just users like you, cannot diagnose that issue remotely, sorry.
I suggest that you contact Apple Support directly (they have tools to check your iPhone remotely), using this link:--> Contact Apple for support and service , or make an appointment (*) and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> https://locate.apple.com/choose-country-region . After checking it out, they'll give you all the available options.
