Perform a factory reset to fully erase your device (Not many devices have SD card slots these days - and some phones are even now using virtual SIM setups, without any physical SIM cards present - so don't fret if you don’t find either item.)īoth cards can be tied to your identity and filled with private data, and there's no reason to keep either of them in a device that’s leaving your possession. Now that your data is secure, take a moment to confirm that your carrier-issued SIM card and any external memory cards are removed from your device. Remove your SIM card and any storage cards Once it's done, though, you can rest easy knowing your data has a powerful layer of protection from prying eyes in the unlikely event that it's even recovered. The visuals will vary from one Android version to another, but most older Android phones will either show you that they're encrypted or give you an option to enable encryption.īe warned that the actual encryption process may take a while, and you won't be able to use your device while the process is underway. In that case, you'll want to follow the steps in that same area to encrypt it and make sure your data is properly protected. The only reason to worry is if you find an encryption setting and see that the device isn't already encrypted. Head to the Security section of Android's system settings and look for the option labeled "Encryption" or "Encryption & credentials" - or just use the search function within your settings to look for the word "encrypt." The exact wording and placement may vary depending on your device's manufacturer and Android version, and some recent phones, such as those made by Samsung, may not even show the option at all (simply because it's considered a given that encryption is in place, and there's nothing you can do to change that). Either way, it's worth double-checking to make sure. But if you're getting rid of an older Android phone, it might not be. If your phone is reasonably recent, it should almost certainly be encrypted by default.
