Does phone pay works if we downgrade software?
With OneUI 8, the camera performance is terrible, and I'm using an S21 FE. Will this method allow me to go back to my old camera? I asked ChatGPT for a screenshot of the video, and they said that OneUI 6.1 was successfully downgraded, but the binary still shows as version 8.I think it understands from the numbers in the build version that it's binary 8, and it says that the camera might still appear that way, so it might not be fixed independently of OneUI 6.Can those who have returned to OneUI 6 confirm that camera quality has improved?
