BigDrewbot, Jul 19, 2019 : My 6t camera app all of a sudden seems to be missing a few modes (e..g Portrait has disappeared) and I can't toggle between front and rear cameras. Can only use the rear camera. It's the standard OnePlus Camera app - v2.9.43. I've read some of these threads and - don't have (or can't find) any way to uninstall updates to the camera app (no triple dots) (there is a toggle to activates Google Lens within the camera app but I don't remember adding and I can't find where to uninstall that - it's the icon to the left of 'Video' mode) - have not installed any 3rd party camera apps - phone is standard Oxygen OS and is up to date (T-Mobile devices OS v9.0.12. Have not modded the OS in any way Please advise!
