Those lenses are available in the stock camera, aperature. It's the same old problem that they're not available in open camera. Now I know why, though, since they're being purposefully restricted from anything that's not on their approved app list. I haven't tried gcam.
You should complain to Xiaomi (do it every day and ask other fts users to do it too).
Do you use the Aryan recommended recovery ? and apply the right procedure ?I experienced a problem with the lock screen. I couldn't wake it up by tapping, and the fingerprint sensor just "pulsed" on the sides of the black screen but wouldn't unlock.
Eventually, I got a pin entry screen to come up, but not the normal lock screen one with the black background. This one had the wallpaper as the background, and it looked a bit different. But it wouldn't accept or reject a pin.
Finally, I tried double-clicking the power button to try to open the camera, and the camera opened. After that, it was back to normal again.
No, I'm using TWRP instead of the LineageOS recovery.
su -c "cmd package bg-dexopt-job" su -c "cmd package compile -a -f --compile-layouts"
su -c dumpsys batterystats --reset-all
Maybe I am too old for that but I prefer XDA more. I did not find Telegram groups to be better communication. Thousands of not relevant posts daily. A huge part of them are 'off topic' or non-English spoken.
