Hey Hope this is the right sub-forum for my question... After looking at some tutorials and threads on the topic of data migration, I'm still confused. Maybe I can get some help here? I want to "migrate" my app (user) data from my Nexus 4 to my Nexus 5. For Google apps that's simple: backup/sync transfers user data between devices when reinstalling. But I also want the data from the non-Google apps. Please note that my phone isn't rooted. I've already tried MyBackup Pro, but on a non-rooted phone it doesn't copy user user data. My questions: (1) Did anyone try the "Helium" app. Does that one backup/transfer user data on a non-rooted phone? (2) I heard you can make a complete backup of your phone's storage through the ADK. Would that be helpful for my needs? (3) Ideally I would like to migrate all user data, but if that's not possible, what I really would like to save is my old text messages and my old Whatsapp conversations. If all else fails, perhaps there's a solution only for those two items?
