Why does iOS say the flashlight has used most of my battery when I only turned it on for about 10 seconds in the last 24 hours? Is this a bug in iOS 8.1.3? It hasn't happened to me before updating!
Omg. You could go into Settings and Reset all Settings. It won't erase any data, but it will reset ringtones and notifications. It's up to you. If that doesn't work, you can either erase all content, or go further and do a restore. Good luck.
