I tried the restore, but not all messages were restored. Why?

There are a few things that can cause this:

  • Not all messages were backed up.
  • The restore process did not finish completely. When the restore completes, it shows the number of messages it restored.
  • Newer versions of Android have a setting for specifying how many messages they will store (defaults to 200) per conversation and any message older than that gets deleted automatically. If you have lots of messages, then make sure the setting is either disabled or has a higher number set.
