Message Sync is an app that allows you to:
• Backup your MMS & SMS messages
• Restore your MMS & SMS messages
• Synchronize your MMS & SMS messages with the backup file
• Import SMS messages from a MyPhoneExplorer xml export
PLEASE REPORT BUGS INCLUDING ERROR MESSAGE!
• Added option to merge the messages when synchronizing the first time on a device (problem where people lost messages when transferring the backup file to a new device).
• Added compatibility for Android 4.4. You will be asked to give permission to Message Sync to temporarily become the default message app (required due to changes in Android 4.4).
• Fixed scheduled backup was not working as expected under certain circumstances.
• Fixed dialog showing nan instead of percentage.
