How To Encrypt - HTC One M8
Learn how to Encrypt on your HTC One M8. On the phone storage, you can encrypt data such as your accounts, settings, downloaded apps and their data, media, and other files. On a storage card, you can only encrypt files. Set a lock screen PIN or password before you start encryption. Fully charge the battery first, or keep HTC One connected to the power adapter during encryption. This process may take about an hour or so.
You cannot undo encryption on the phone storage. If you want to return to an unencrypted phone, you must perform a factory reset. Once you enable storage card encryption, only new files added after encryption will be encrypted. Files already on the card will not be encrypted. Also, storage card encryption doesn't reformat or erase your card. Encrypted files on the storage card can only be opened by the phone that encrypted them.
- Go to Settings, and then tap Storage.
- Tap Phone storage encryption. Or, tap Encrypt SD card content.
- Tap Next.
- Enter the lock screen PIN or password, and tap Next.
- Tap Enable encryption.
- During phone storage encryption, the phone may restart a few times. When storage encryption is complete, enter your PIN or password.
If you turn off SD card encryption to stop encrypting new files, previously encrypted files will remain encrypted. To access these files, you must enable encryption again for your storage card.
