[AC Question]

I have a HTC ONE M8. I've started getting the message "People has stopped unexpectedly. Would you like to send an error report to HTC. No matter what I do the message doesn't go away and I can access my contacts and phone book. The phone is not rooted as I have no idea on things like that.

Hold the power button down until the phone starts to restart (it could take up to 30 seconds). It should restart without that message, and Contacts may work or it may stop. (If it still stops, you have a software problem and should start a separate thread.)
