  • Backup info and data from installed applications using these apps: Titanium Backup (here) or Helium (here) from Google Play.
  • SMS, Call Logs info and APN Internet Settings can be saved using the following tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access is required for some of these tools.
