Frequently Asked Questions
How to unlock Samsung M21 without password?
The Samsung Galaxy M21 2021 can only be unlocked without the password through official recovery methods, and a factory reset may erase the phone’s data. If Samsung Find My Mobile or Google account recovery was set up before the lockout, those services may help restore access. After a reset, Android security may require the previously synced Google account or Samsung account to verify ownership before the phone can be used again.
How old is the Samsung Galaxy M21?
The original Samsung Galaxy M21 was announced in March 2020, while the Samsung Galaxy M21 2021 is a later 2021 version of the same M21 line. That means the original model is about six years old in 2026, and the 2021 version is about five years old depending on the exact purchase date. Its Exynos 9611 chipset, 60Hz display, 4GB RAM, and 64GB storage place it in an older budget Android category today.
Does the Samsung M21 2021 support 5G?
The Samsung Galaxy M21 2021 does not support 5G, as it uses the Exynos 9611 chipset rather than a 5G-capable platform. It is better suited for buyers who need a low-cost Android phone for standard mobile data, calls, messaging, and media playback. If 5G connectivity is a priority, a newer Samsung model with an explicitly listed 5G chipset would be a better choice.
