My phone just got factory reset and I forgot to save the contact, and when I tried to log into my Viber account on other devices, the messages are gone. Can I still recover them after reinstalling even if the backup was turned off?
If you haven't backed them up before, try MobiKin Doctor for Android, it has poweful method to detect the internal storage and will help you extract the deleted data as long as it hasn't been overwritten by new files.
