Can’t speak for every S22U model out there but I’ve had no overheating issues with mine, and the battery is perfectly fine. Snapdragon model, been using for 18 months

I’ve used a S22U for over 1.5 years, and have just upgraded to the S23U.

With the right case, the edges are a non issue.

Given it’s such a big phone you need a case that allows you to handle it properly. I use either a strap case or the cases with flip stand that I can use to get a better grip.

It’s definitely not one for someone with small hands lol.

Absolute almost perfection.

I have no issues at all with any apps. Only hiccup recent was with Spotify kept crashing but that’s an app problem not an OS issue I think.
