The back glass is lifting off my iPhone 8 at the bottom, and I don’t want/need to replace it. Will it cause any issues if I use super glue around the edge? I don’t care about water resistance. If super glue is a bad idea, are there any other viable options?
Yeah super glue should be fine as long as it’s only coming up in one section. You won’t have to worry about getting the alignment wrong and then it’s super-glued down…If the glass does break at any point and you want to replace it, you will have a hard time removing the pieces of glass directly glued onto the frame from your super glue.
