About changes to theme splash screens (with LINE version 12.5.0 or later and themes sold from April 2022) toggle
Due to Google policy and specification changes, unique theme splash screens (the screen that appears when you open the LINE app) no longer appears. Instead, LINE's default green splash screen is used.

This change is applied to themes that were sold up to March 2022 after updating to LINE version 12.5.0 or later. Additionally, the default green LINE splash screen appears for all themes sold from April 2022, regardless of which LINE version is being used.

- "This message can't be decrypted"

⋅You transfer your account to a device with a different OS (e.g. iOS to Android).
Note: If you transfer your account to a device with a different OS, you cannot transfer your past chat messages.

About the backup PIN toggle
By registering a backup PIN beforehand, you can automatically transfer your chat history from the last 14 days when you transfer your LINE account, even if you can no longer use your old device due to loss or damage.
Note:
- To transfer your chat history in this way, you need to update LINE to version 12.13.0 or later.
- You can update the LINE app here.

To set a backup PIN:
1. From the Home tab, tap Settings > Back up and restore chat history under Backup and transfer.
2. Tap Back up now or Create backup PIN and back up chat history.
3. Enter your backup PIN.
4. Tap the arrow.

Keep a memo of the backup PIN you set so you don’t forget it, as you'll need it to restore your saved chat history when you transfer your LINE account.

To prevent your backup PIN from being used by someone else without your permission, also make sure that it is difficult to guess.

Here are some tips for setting a hard-to-guess backup PIN:
• Don't use consecutive numbers (e.g. 123456).
• Don't use the same number repetitively (e.g. 111111).
• Don't make the PIN your birthday.
