Last night and today when I turn on my 8+ if I wanted to make a phone call when I press the first number I hear the tone sound which does not stop until I completely close the phone icon. Also if I try to text someone and press the first letter of their name their contact does not show up where it says To. I don't know if it's a software problem because I want to download iOs 12, however it's saying 3 hours just to back it up. I got an Apple appointment at their Genus Bar but it's not until next Thursday at 4:10 PM. I thought of going tomorrow morning when they open but not sure if they will be able to see me. So has anyone had this problem before?
