I use my phone for GPS, alarms, etc. After the latest lollipop update, it has been turning off when it's hot. This is a problem while driving and using it as gps. I have to pull over repeatedly to let it cool down, turn it on, and enter the address again so I don't get lost. I'm now worried it'll do the same thing while I'm sleeping and I won't know to get up for work. Help!
