Xperia Miro problems. Please help.

[PizzaToTheRescu]

So, I rooted my Xperia Miro ST23i and installed one of those uninstall system apps software. 

By mistake I uninstalled my contacts app. Now I can't save any numbers. I downloaded Contacts+ app on the play store so I can call but cannot add new contacts. Please help.

Go to Settings--Apps--All--scroll down to the bottom--look for the app Contacts. If you find it, tap it and tap Enable.

If you don't find it that screen, then try this. First try to make a backup of all your contacts. If you have it already on your sim card or some place else, then go on. If you don't have it already, try using an app from Play store to back up your contacts.

Then try restoring factory settings: Settings--Backup & reset--Reset settings. Reboot.
