Mail text disappearing on iPhone Friend of mine has an iPhone and no other electronics. Says that 


  It seems like messages come and go. No content then there it is. I
  read one message then the other. Went back to the other and it was
  gone. Happens a lot. Then it turned up again.


I am a long way away, and she is very non-technical. So I am really not sure how to help. What should be done?
With the advancements in iOS, a variety of apps are now available that makes it possible to provide remote assistance (just like in Desktops). A couple example os such apps are:


Zoho Assist: Remote Support for iOS Devices.
TeamViewer QuickSupport.
