I upgraded my S2 to the latest config using Kies - nothing exotic just standard.
The upgrade seemed to go well and the phone rebooted ok.
I then updated snapchat and put the phone down.
10 Minutes later the phone was very warm and refused to turn on.
I was then told that the data on the phone was precious (!!) and now need to recover that d
My S4 was recently updated to 4.4.2 from 4.2.2. I'm on ATT. It's not rooted. I never used Kies but I noticed the other day it was gone. IF I were to do a factory reset, which is something I am hesitant to do, I'd want to back up everything obviously. I DID download Samsung Smart Switch from the Play store, but Kies seems to be gone from my phone.
