This is my wife's phone, its stock not rooted or anything. I used to like this phone but after the update its bogs down, things freezes and battery life is worst then my nexus. anyways, she has been complaining that her hotmail email doesnt sync anymore and few other issues. I just test her email by sending it a test from phone to both her gmail and hotmail, it notifies of the email but however the drop down menu in the email app (stock) is blank. I read that a factory reset would fix any issues. question is how do i reset the phone? How do i back it up since i read this will wipe all the data from the phone. again this is my phone so im not familiar with it. thanks
