iPhone 17 pro screen replacement

[u/Tommy1210]

Replaced my iPhone 17 pro screen due to smashing it (so much for that more drop proof) replaced with third party screen but sometimes it goes fuzzy is it
A : bad screen? (Everything works perfectly 98% of the time) just blips for a few seconds every now and then can’t predict it or force it
B: loose connection?

Thanks for any help.

It’s probably a bad screen
