Damage from removing back cover
I previously had my battery replaced. And then my screen cracked, so I decided to repair it myself. When I removed the back cover, the previous tech had damaged then put adhesive on the the small printed circuit decalsjust under the cover in the corners. Now they are torn. I completed the repair and placed them back as best I could and everything still seems to work, but what are these for? Can or should I replace them?
Is this a good question?
