Since the last update my phone has been really buggy I have the iPhone 11 and when people try to call my phone it will ring put sometimes it will not pull up anything to let u answer the phone . It has also when I message people started showing up as my email address instead of phone number and then it can say it has a full battery or all the way to a little under a half and it will power off saying the phone died and connect to my charger. I put my phone on the charger and powers it on and even checked the battery info and it says my battery is good I did not start having these issues until the last update was installed
