Just started using my iPhone 7+ and having a few problems with it Firstly, my wifi keeps dropping Secondly, and the biggest probably, if I'm on the phone whilst trying to google something or use an app I get the message "A data connection cannot be established because a call is currently active". Also, if someone FaceTime audio's me, it takes forever to connect, if it connects at all. But this is usually only in the evening mostly. As well as that, sometimes FaceTime audio calls drop their end but my end stays connected and the timer carries on going up until I hang up and call back. Lastly, my headphones controller randomly stops working and I have to unplug it and replug it in. Usually after I've listened to a podcast for a while, when I come to use it, it's stopped working. I'm running the latest iOS, on Vodafone in England. Only got my iPhone delivered due to the delays 2 days ago. What should I do?
