After upgrading my S21 ultra 5G, the battery percentage icon disappeared despite it is enabled from the settings.
open sittings and chose battery and device care then chose battery >more battery sittings > show battery percentage turn it on
I did, but not working. It shows 0% and when I restart phone, it disappears again.
الضبط-الإشعارات-الضبط المتقدم-من ثم قم بتفعيل عرض نسبة شحن البطارية
تماما هكذا فعلت لكن تظهر نسبة 0%وعندما اعيد التشغيل للجهاز تختفي
There is no other way to solve the problem you are facing other than to perform a factory reset of your phone via recovery
It can be a bug, try reporting the problem to samsung
How can I do that?
You can chat with them and report errors
