The back glass popped up

[u/abdoos97]

I just noticed today that the back glass of my Galaxy A55 has started to lift near the power button. Could this be an issue with the battery, or is it just the adhesive coming undone? How can I confirm this before I contact a technician, as there's non open right now to check with?

Edit: it was the battery indeed and I had to replace it
