Samsung Galaxy S21 Ultra - Black 512gb storage

guy scammed me with a messed up samsung s21 ultra screen and backing have been opened and I think we're not completely problem Installed back as it's poping out a little but I'm pretty sure if you know what your doing you can get it fixed. there is also dirty lense inside the camera but again if you know what your doing you should be fine and I think the camera is not damaged as it does work without issues ( besides seeing the dirt on the lense). these can be fixed easily from a shop your self but the only major issue is the volume down button doesn't seem to work. I don't know if something got inside or it's broken but that's the only thing that made me want to just get rid of the phone now it's a samsing s21 ultra 512gb black it's unlocked and it still works fine normally. other than those the phone is in pristine condition all other features the body shape is pretty good I have lowered the price to sell so unfortunately I really can't do super low offers you can take a look at it in person and check it out fully before you purchase 👍
