I’ve read that people are putting glue at each corner. I haven’t figured out what glue. One person said Glue Dot 1” 16lb, another said rubber cement, 1 video shows 5 min epoxy… Heard that some sort of glue (not super glue) needs to be used to avoid the glass lifting later on. And to use 3m red tape along the edges. I’ve been searching for which glue because I still have an ipad air to do screen replacement on.
