okay so for the past couple of days my phone has been severely lagging from time to time and in the past 24 hours ive gone from 26gb of free space to 3.5gb. In iTunes its showing 26.6GB of "Other" being used and on the phone its not listing anything thats taking up that amount of space. Also the device has gotten extremely warm over the past couple of hours. What is going on? Its an iPhone 6 Plus 64GB running iOS 9.1 PB. Im thinking of restoring it but I don't want to loose all of my health data from the past 6 months but I'm thinking that I may have no choice.
