Others DIY it by buying a special kind of glue, I thinks its B8000 or T8000 glue, and stick back the back panel again by themselves.

Thank you for your reply, I was found same problem here. Last 2 days ago, my son's Samsung A52S had another issue with water drop icon and can't charge. Then, I was used hair dryer and blew at usb c charging port about 1 min. Then back cover was came out. The handset can charge, can use, everything is fine after half an hour then.
I don't know how to fix back cover, even warranty was over. But I decided to go Samsung service center in Singapore. I went service center today. The lady at Q counter checked my handset and go and ask to technician. Technician told her, my display need to change due to the glue line was at display side, so display need to change. cost about 150s$. I was surprised hear that. Is it necessary?
The service in Singapore is very terrible!
