I've been Android for several years, but have watched as iPhone has evolved device more suitable for me, so thought I'd give it a go. Largely, I love the phone and a lot of stuff about it. But there are several niggles which have made pine after Android. - Phone call cancels navigation. When driving using the phone as navigation, if someone calls, the whole screen is taken-up with the phone app. As it's illegal to touch a mobile phone whilst driving in the UK, technically I'm unable to get my satnav back until I hang-up. - iMessage. Seems like a great idea, but my girlfriend (who is iPhone) has gone back to Whatsapping me because messages were disappearing. - Camera often doesn't open. I just get a black screen and need to flick to video and back to photo for it to work. - Can't swipe from bottom if keyboard is open. - Can't turn off Calculator sounds - Zero idea of missed messages/email unless you go looking for them. Driving is a prime example - I now have to check when I finish a journey to see if I've missed anything. And fingerprint unlocks the phone so quickly, it's already unlocked before it's out of my pocket, so I don't see notifications on the lock screen. - Lack of headphone jack has become a bit annoying as twice I've forgotten the adapter.
