You will get many more errors while using phone, don't understand why Samsung pushes OS update except security ones when it can't handle this. Now my s21fe have many issues like overheating, removal of magnetic eraser in gallery, superfast draining of battery etc. Phone is behaving weird and feels downgraded instead of upgrade. Samsung should release a new update for atleast its own exynos chip containing devices.
