The Samsung Galaxy A51 (SM-A515F) remains one of the most widely used mid-range smartphones, thanks to its excellent hardware and user-friendly form. However, as Samsung ends security updates for many devices released before 2020, Galaxy A51 users increasingly turn to custom ROMs to breathe new life into their devices.
