GALAXY S4:
Android 4.4.4

The app don't let to backup messages to internal storage or cloud external storage. Please correct this issue.

Yes this would be lovely.

Love the app and have been using it since it hit the market. I have highly customized settings for a number of users. After the recent purchase of a new phone, I find that I'm still making adjustments nearly a month later. Ability to back up settings would be fantastic!

Better yet, JUST IN TEXTRA. Signing into our individual accounts, we must have the ability to backup & restore messages, all settings, and/or saved items. I left handcent and this was their best feature as i had numerous settings too tedious to reapply everytime i switched phones!

Add me to the list of people that would like the ability to backup settings. I hate to customize all my contact colors and what not just to have them wiped out when I change phones/factory rest/flash a new ROM.

It would be nice if the native Android Backup worked (see link below) or even a manual backup.

And it should not be a bulk back up like Go sms pro.
It should be a synchronized backup, which synchronizes local and cloud sms. Let it be a paid feature.

This is an absolute must.

I agree w-Ferrel, at least provide a method or way to backup all settings for reinstall purposes.

Cloud/Email of settings &/or messages would be nice as well. With all the customization Extra allows, you really need to Backup settings as it is easy to spend 30minutes rebuilding your settings (I know I just FDR phone and spent almost one hour verifying all personal settings.

I would like to at least be able to backup settings for new installs (or reinstall).
