For me, I think a little before but it's definitely got worse since the December update.
zero issues here before or after the update. No crashes at all.
Another issue I keep forgetting to flag on here - the telephoto lens. Mine does that under water effect when trying 2x, sometimes it resolves itself and others it doesn't.
Any one else experience a similar thing?
You mean opening blurry? I used to have that with my S8+ and I figured out if I put it back down on a surface it sort of kicked it into refocusing which sorted it. Frustrating though if it's the same thing.
