This device has expired. Now what?

No more security updates will ever arrive for the Samsung Galaxy M21. If it's your daily phone, the safest move is to replace it — ideally with a model that stays supported for years. The old one still makes a fine offline camera, alarm clock or backup device.

The Samsung Galaxy M21 in detail

How many years of updates does the Samsung Galaxy M21 get?

Released in March 2020, the Samsung Galaxy M21 received security patches until March 2024: 4 years in total.

Among the 258 Samsung phones in our database, 94 were supported for less time and 132 for longer. The median is 4 years and 1 month.

Across all brands, the median for phones is 4 years.

The last patch came out 2 years and 7 months ago.

Two schedules overlap here. New system versions stop in March 2022, security patches in March 2024. In between, the device stays on its last version but still gets fixes for security holes.

Can I keep using the Samsung Galaxy M21?

Yes, it still works. But every security hole found after March 2024 stays open. For daily use with banking, messaging and passwords, a supported device is the safer choice. As a spare without your main accounts (alarm clock, music player, camera), it's still useful. Do a factory reset before you give it away or recycle it.
