@ezekiel9898 unless you are the original owner and know what repairs have been done on this, it could be tricky. There is always a chance that somebody got wild with same crazy glue or similar. Get some high grade isopropyl alcohol 95%+ and a syringe. Then inject some of the alcohol between the case and the frame of the display. See if that softens things up. Bottom line here is that you may potentially lose the display since it may crack.
Post some pictures of what this all looks like so we may come up with more "ideas" on how to help you with that. [guide|21499]
