So Am a current Note 4 user, used the Note2 prior, and am considering a few phones when my contract is up. I haven't used an iPhone Since the 3gs, but have a few questions. Would probably be looking at the 6s plus or some variant of the 7 How much of a learning Curve am I in for? Can I still use One Drive to back up my photos/videos automatically when connected to wifi? I use an app to hide photo's on my phone, Can I do this with on iPhone? ( Gallery Lock Pro ) or something similar? The app itself is hidden as well. Can use multiple email accounts on iPhone? Assuming this is yes, but just want confirmation.
