"This message can't be displayed" appears and I can't see sent/received chat messages

If you see any of the following messages after transferring your account on a smartphone, you may not be able to view past chat messages.

- "This message can't be displayed"

- "This message wasn't backed up and restored from your previous device. Unfortunately, there's no way to read it on your current device."

- "Unable to display message as it couldn't be decrypted."

The messages above appear when:

• You transfer your account to a device with the same OS (e.g. iOS to iOS) without backing up and restoring your chats.

If you back up your chats on your old device before transferring your account, you can view them on your new device. For the steps to do so, see this Help article.

• You transfer your account to a device with a different OS (e.g. iOS to Android).

Note: You cannot transfer your past chats.

• You receive chat messages while transferring your account.

Any such messages cannot be transferred to your new device. For more information, see this Help article.

If any of these messages appear and you cannot view your past chat messages, there is unfortunately no way to re-display them. In this case, please ask the other person in the chat to send you any old messages that you need.

About using your smartphone's unlock method to log in to LINE

Required settings for logging in to LINE for iPad or PC with your smartphone's unlock method

To be able to log in to your LINE account on an iPad or PC using your smartphone's unlock method, you need to:

• Set an unlock method on your smartphone.

• Allow your smartphone's unlock method to be used for logins in the LINE app.

Setting an unlock method on your smartphone

For iOS:

Use Touch ID on your iPhone or iPad

Use Face ID on your iPhone or iPad Pro

For Android:

Check your phone manufacturer's website for details on how to set an unlock method.

Note: LINE will never save your unlock method.

Allowing your smartphone's unlock method to be used for logins in the LINE app

1. Tap the Home tab > Settings > Account.

2. Tap Face ID/Touch ID for iOS or Device unlock method for Android > Enable.

You'll know setup is complete when you see Unlink in the field for Face ID/Touch ID or your smartphone's unlock method.

Using your smartphone unlock method to log in is more secure because you are the only person who can use it.

You can increase your account security even more by not allowing logins with an email address and password. To only allow your account to be logged in to with your smartphone's unlock method or a QR code, tap the Home tab > Settings > Account and turn Log in with password OFF.

Note: Turning Log in with password OFF will not log you out of any devices you're already logged in to.

Transferring your LINE account with a phone number

Backing up your chat history

To restore your chat history after transferring your LINE account, you need to back it up beforehand.

Note: Photos and stickers sent in chats cannot be backed up or restored. If there are photos you'd like to save, consider saving them to Albums or Keep.

Before backing up your chats, be sure that:

• You're using the latest version of LINE. (Update the app here.)

• iCloud Drive/Google Drive is turned on.

Note: This feature is unavailable on Android devices that cannot use Google Drive.

• There is enough free space in iCloud Drive/Google Drive.

Note: For information about clearing space in your storage, see this Apple Support page or this Google Drive Help page.

Even if you cannot back up your chat history because your device was lost or stolen, you can automatically transfer your history from the last 14 days if you set a chat history backup PIN. See this Help article for more information.

For the basic ways to back up your chat history, see below.

iOS users

There are two methods available for backing up your chats to iCloud Drive.

Manually back up chats to iCloud Drive

1. From the Home tab, tap Settings > Chat history backup under Backup and transfer.
2. Tap Back up now.
Note: If you don't see Back up now, you need to set a backup PIN, so tap Create backup PIN to back up chat history.

Automatically back up chats to iCloud Drive

1. From the Home tab, tap Settings > Chat history backup under Backup and transfer.
2. Tap Back up how often.
3. Select how often you want to back up your chats.

You can also watch this video to learn how to configure your settings. (Video only available in Japanese.)

Your chats will only be backed up automatically if your device and settings meet the conditions below when the auto-backup refresh starts.
• Your device is plugged into an outlet.
• Your device is connected to the internet.
• The Background App Refresh setting on your device is ON.
Note: For details on how to turn on Background App Refresh, see this link.

Android users

There are two methods available for backing up your chats to Google Drive.

Manually back up chats

1. From the Home tab, tap Settings > Back up and restore chat history under Backup and transfer.
2. Tap Back up now or Back up to Google Drive.
Note: If you don't see Back up now or Back up to Google Drive, you need to set a backup PIN, so tap Create backup PIN to back up chat history.

You can also watch this video to learn how to configure your settings. (Video only available in Japanese.)

Automatically back up chats

1. From the Home tab, tap Settings > Back up and restore chat history under Backup and transfer.
2. Tap Back up how often and turn Enable auto-backup ON.

Your chats will only be backed up automatically if your device and settings meet the conditions below when the auto-backup refresh starts.

• Your device is plugged into an outlet.
• Your device is connected to the internet.
Note: If you can't use a Wi-Fi connection, you can still back up your chats with Use mobile data selected.

Your chats will be backed up automatically when you stop using your device and its screen has turned off.

If an auto-backup fails, you'll receive a chat notification from the LINE official account. For more information about this notification, see this Help article.

Sharing posts to your friends on LINE

With LINE Timeline (the service we offered before LINE VOOM), there was a Friends privacy setting that let you share posts to only your friends on LINE. However, this privacy setting can no longer be used after you select the friends you want to follow on LINE VOOM from the From friends to followers pop-up that initially appears.

Instead, you can share posts to just your friends on LINE by using the LINE friends custom list that is automatically created after you initially set up your Following list.

To share posts to your friends on LINE:

1. On the post editing screen, tap Public, the custom list name, or Only me.

Note:

- The post editing screen will appear after you make a post.

- The privacy setting you choose will remain selected for your next post.

2. Select Custom lists > LINE friends.

3. Tap Save or OK at the bottom of the screen.

Keep in mind that the LINE friends custom list will not automatically update after it has been created. If you don't want to share a post with everyone in the LINE friends custom list, you can delete users from it by tapping "-" > OK or Delete.

If you have a new LINE friend you want to share your posts with, follow them and add them directly to the LINE friends custom list. See this Help article for details.

Important: If you block a friend on LINE after initially choosing who to follow, the LINE friends custom list will not automatically update. To prevent your posts from being seen by user you blocked on LINE, you will need to also block them on LINE VOOM.
