The back panel on my galaxy s20 exynos has started to come off.

It has started to peel off near the camera lense, so I do not suspect that it is a battery issue. Would this be cheap to fix?

It should be as simple as replcing the adhesive holding your phone and the back panel together so it should not be to much to fix
