Its been 2 years since i bought A52 4g. I just noticed todaythat back cover of my A52 4g is coming off on its on. Seems like the adhesiveness has worn out over time. This is very evident that how Samsung is using such a cheap quality back cover poorly glued. Everyone who is using A52 4g/5g A52s should also check their phones because this issue is very common with samsung $hit.
Moreover, these phones come with IP67 rating as advertised, but with such issues like back cover become loose poses a great risk to the phone. So, have check on it.
Check if Ur battery is not swelling. My cell phone's back cover came loose on its own and when I checked the battery had swollen quite a bit. Had to discard that cell ..
Battery is perfectly fine. Just the adhesive is gone after two years of normal usage. Moreover, I don't even play games on it, nor had any heating issues due to overuse or overcharging. Samsung phone build quality is deliberately made that cheap so that a user needs to buy another one after two or three years of use. Now even if I re-apply the back adhesive, the IP67 has ended up already.
