So I have had my iPod touch for a while and recently some splotches appeared on the screen I am unsure how to fix this or replace the screen (side note I also cannot get the case of easily but let’s assume I can) I don’t know how to fix this or replace it, how do you? Edit in picture screen is just on white picture

There’s already a guide on this website that you can follow. It’ll show you how to replace the LCD screen but let me warn you that it may be difficult to do. Here’s the link iPod Touch 4th Generation Front Panel Replacement
