Samsung ends software updates for 3 Galaxy phones
Legit.ng earlier reported that Samsung has officially removed three popular Galaxy smartphones from its software update eligibility list for May 2026, ending regular security and firmware support for the devices.
The affected models are the Galaxy A13, Galaxy A23 LTE, and Galaxy M33 5G. With their removal from Samsung’s update chart, users of these devices will no longer receive routine security patches or firmware improvements.
While the phones will continue to function normally, the lack of software updates means users may become more exposed to security vulnerabilities over time.
