Hi...something weird happened today. I took my Hero 4 out of the bag and found it very hot and with the battery empty. I have never used it - literally I just bought it! - and in my bag I keep it in it's housing which is in a soft case. I have the quick record option turned off and the card was empty, so it wasn't accidentally recording. What happened? Did some buttons get pushed and it turned on? I think I have auto off enabled though. Did the wifi get turned on? I'm really lost...I'm not too worried but I would like to prevent this from happening again! Let me know if you have any ideas...thanks!!
