I want to know that if I install an older firmware of my device, is it safe to download it from samfw.com? I don't like OneUI 7 anyways because a lot of reasons like it's not optimized with battery drain and other stuffs, I want to go back to the older version. At least older version is better ans optimized than OneUI 7. Let me know please.
Any site other than official Samsung site is RISKY. Since you speak of downgrading there is a strong possibility of your phone going dead. I would recommend to keep one UI 7.0 and wait for one UI 8.0 which may address your concerns.
