Great phone still, only downside is its battery. Degraded after 4 years of usage. SD 870 works like wonders. Hope it got more updates. Install Pixel Experience, cameras great and overall its still solid in the big 25.
Bought it in Aug 4 2021.. Installed a custom rom on it and changed the battery after 3.5 years, still a great phone and it functions so well
Still works wonders, although I did experience deadboot after about two years. I got it reballed and it still works
