After one ui 7 update battery is draining too fast, even with minimal settings in S21 Fe 5g.

Hi all,Wifi calling is not showing anymore after Nov 2024 security update. I have tried changing setting and rebooting the phone, clearing cache, & connecting & disconnecting wifi, but still its not working. What to do now?

After the recent system update(September) microsoft apps (outlook, teams, onenote) are crashing continiously. Please look into this.

Hi, I recently downloaded a few files from apps like paytm or other app and the files were in pdf format, but i could not find the files in "downloads" in my files app. How and where can i locate these file on galaxy s21 fe 5g?

After the latest may update battery is draining too fast. Now phone needs to be charged 2 times a day to use it, that too with not heavy usage. Earlier update was better, battery was stable and did not drain fast.
