Can I Recover Email Address That Have Been Signed Into On My Galaxy Phone?? When I factory reset my phone, it had signed me out of my Gmail account that I had created and used for my Google Play Store. And now I cannot remember what the exact email address was. 

It has my SMS backup and restore on it and all of my pictures and contacts and important info. Is there a way to find out what the email address was??
All account data on the phone is lost after a factory reset. Perhaps you can use a different way to find that email address, however.


Did you ever send email from that account to one of your other email
accounts? What about to a friend or family member? See if you can find one
of those old messages.
Did you ever log into a Google service using that account on a PC/Mac
browser? If so, maybe you can find it in your browsing history or
saved passwords.
Did you link that Google account with any other online service? Did
you create a Google+ account with that address? You might have if you
ever wrote a review of an app in the Google Play store. Try and find your Google+ profile.
