What this means for you
Once a device stops getting security updates, newly discovered vulnerabilities stay unpatched, and the risk grows over time — especially for banking, email and anything holding personal files. The Samsung Galaxy S21 won't stop working, but it's no longer a safe place for sensitive activity.
Your options
- Keep it, with care. Use an up-to-date browser, avoid sideloading, and move banking to a supported device.
- Make sure it's backed up — see backing up properly.
- Replace it when it no longer fits your needs; what to look for in a phone you keep covers what matters.
