What if my last backup says "Never"?

1. Enable permissions for Signal:
   Android Phone Settings > Apps or Apps & Notifications > Signal > App Permissions or Permissions > Enable all permissions.
2. Free up space on your phone. 
3. Temporarily unmount or disable your external SD card so the backup can be saved to your internal memory.

Where can I find the backup file?

• Your backup folder is listed under Signal Settings  > Chats and media > Chat backups > Backup folder. Use the files app or plug your phone into a computer to go to the folder.
• For older versions of Signal, the backup file signal-year-month-date-time.backup can be found at  /Internal Storage/Signal/Backups or /sdcard/Signal/Backups

Where do I move the backup file?

Move the backup file signal-year-month-date-time.backup to a device that is not your phone.

What do I do on my new phone or phone that was reset?

1. Manually move theSignal folder with the backup file to your new phone. For older versions of Signal, move to the top most level or /Internal Storage/ on your restored or new phone.
   • A common method is to use a cable to plug your phone into your computer. Some phone's require you to use a cable that was provided with your phone in order to transfer data.
     • Recent phones offer steps in Android Settings > Storage.
     • You may need to respond to the notification that appears on your phone to change the mode to Transfer files (MTP).
2. Install Signal.
3. Select Restore backup. If it is not available, Select Continue.
4. If you selected Continue in step 3, then
   1. Accept the permissions.
   2. Signal will automatically detect your local backup and ask you to restore before registration. If it is not detected, try the steps below.
   3. Select Restore backup.
5. If you selected Restore backup in step 3, choose the backup folder and file.
6. Enter your 30-digit passphrase.

What if I forget my 30-digit passphrase and need to restore messages on a new phone?

You will be unable to restore a backup without the passphrase. Think of the 30-digit passphrase as a key that can not be duplicated. You can create a new backup to create a new passphrase.

Go to Signal Settings  > Chats and media > Chat backups

1. Tap Turn off to disable chat backups and delete all previous backups on your phone.
2. Tap Turn on to create a new backup with a new passphrase.

I need some more help.

• Make sure you moved the backup file to your new phone, or moved it onto your phone that was reset.
• Some devices may need to power down and restart to see the backup file.
• Make sure the backup file is visible. As a reminder, backup filenames follow this format: signal-year-month-date-time.backup
• Enable all the permissions for Signal.
  • The media permission is required in order to locate backup files on your device storage. 
• Here's another way to make sure your backup file is in the correct spot on your new phone. 
  1. On your new phone, register for Signal without a backup (your old phone will now go offline).
  2. Enable a backup on your new phone.
  3. Find the new backup on your new phone and write down where it is. Look at the file name to confirm you just made this backup.
  4. Uninstall Signal on the new phone.
  5. Carefully find your old backup. Look at the date and time in the file name. 
  6. Move the old backup to the same folder you found in step 3.
  7. Install Signal.
