I have been buying Sony phones for years, but I was offered a good deal on a Samsung S21 Ultra by my carrier, so I switched.  The S21 Ultra phone is OK in most respects, but I loathe, loathe, LOATHE the camera app.  It's slow, overly complicated, and worst of all it doesn't record about half of the pictures I take.  I sometimes use my old Sony Z1 phone's camera when I know I'm going to be taking pictures, but I don't want to be lugging two phones around all the time.   I looked in the Play store for an alternate camera app but I didn't see any alternatives that jumped out as being better.  I'm beginning to think it's a known problem and that's why my carrier was discounting the S21 Ultras.  But for now I'm stuck with the S21 (it's not even entirely paid for yet) so I'm wondering if there's a better camera app than the one that came with the camera.  Any ideas?
