Hello, does some one have problem with camera software?
When you take pictures it needs a lot of time to make picture in back proces. Quality is worse than on android 11, and on android 11 it never worked in backround to make picture.
It could happen if you have system mode as "Performance" with all switches (CPU, GPU, RAM etc) to leftmost position.
It also could happen if you make picture in night mode.
It doesnt matter in wich mode it is, and its not night mod as well
I have the same problem since updating the system to android 12. Often photos are blurry and take a long time to load it after taking.
Enter app settings and clean storage & cache data. Restart. It worked for me.
This is often what causes issues, clean your cache data and it should be back to running smoothly :D
