When using the iphone 6 Plus. I use iMessage and then attach a photo or take a photo... the app does not show the camera fully or even to attach a photo does not work. I have about 8-9000 phones and like 10 short videos in there but it is incredibly slow and almost unable. I have the 128GB iPhone 6 Plus with 46gb still available. I think this should not be so slow with so much memory still available. Please help. I am using 8.1.2. Yes I have set up the phone as a new phone. Apple store even reformatted this iphone 6 plus 2 months ago but it is still terribly slow. I got the phone like a week after being out. Thanks
