Recently I’ve noticed, the back glass on two of my phones has started to come off. Like I can put a fingernail between the frame and the glass and if enough pressure is put, I’m pretty sure I can just remove the back.

It’s happened on my Note9 (backup phone) and now on my S20 Ultra (main). I’ve been using a case on both since I got them. They’ve never had any repairs or anything I think that would make the back glass come off.

Note9 has been dropped a few times but nothing major and my S20 Ultra has never been dropped at all.

Obviously this issue gets worse if the phone heats up if gaming or doing any phone-heating-up activities. Also means I no longer have any water and dust resistance on both of these phones or none that I can trust to keep all that stuff outside the phone.

Surprisingly my old S8, which just sits there, does not exhibit this issue.
