The phone gets stuck in 3G or No service randomly. For example, I was at a friends house and we were looking stuff up on our phones, I was sitting in the same spot for 20 min, my phone went from LTE to 3G, I reset my phone. Back to LTE, 15 min later it went to 1x then no service. I was sitting in the same spot. This happens multiple times throughout the day. Sometimes I can't make or receive calls even though someone sitting next to me with a 6s can. If you google it, there are MANY MANY others having the same issue. My husbands does all this plus has wifi issues and disconnects his bluetooth randomly. Its a really buggy phone :/
