This is probably more to do with Apps than the phone specifically but my phone is the S2. I'm curious about the Mobile ID app and what it is. I did do a google search and I understand what it does but it doesn't seem to be working. When I select it, it brings up a screen that says "Welcome to Mobile ID". It says that basically the download failed and gives me the options "cancel" and "retry". I select retry and it goes into download mode. Then it fails. I'm on wifi. Any Ideas?
