Why did my iPhone 4s restart randomly?
My iPhone restarted when I was updating the Facebook app (on my home WiFi network.) and couple of other apps were also open in the background. As soon as I headed to safari to look for something, iPhone restarted.
I Don't know what caused my iPhone to restart.
Though i was using it for more than 4 hours after changing it to 100%.
The iPhone 4s I have is more than an year old and it's running the latest version, iOS 7.1.2.
i haven't tried any troubleshooting steps so far But I was thinking to drain the battery till it goes off and then charge it to full.
Please, suggest me what to do now and make sure it won't restart anytime soon in future.
