why you dont have option to show hide battery percentage above battery health?
it’s prolly hardware issue… I think most users are on sep patch. no one reported stuff like this.
may be unit specific? but not sure how can update only affect one device…
its understandable if its screen issue coz thats normal thing these days. even if it was update issue. it wont just blow any option from settings like that unless its mentioned in changelog. I think its battery issue, may be loose connection or idk but yeah. only center can fix it. you will have to pay I guess since its out of warranty.
