iPhone 64 GB on iOS 6.1.4 randomly freezes.
I am still running my iPhone 5 64 GB on iOS 6.1.4 and everything functions great, except for FaceTime of course, but sometimes my phone will randomly freeze and then resume to the action I was trying in the first place. Ex: I will double click my home button and it takes a few seconds longer for the screen to move up so I can exit my apps. I have 24 GB of storage left so I don't think it is a memory issue. Any ideas? Thanks.
