Hey, so when ever I make a call (I can dial but when I hit call) my phone will lock up, then the screen goes black, shuts off and turns back on. It happens when I answer or reject incoming calls as well. This only started happening when I updated my S5 to lolipop, I unrooted, and when back to the S5 stock kitkat ROM, full factory reset before going to lolipop, phone calls worked fine rooted and unrooted in KitKat, so it makes me think it's a lolipop issue. Since running into the problem I've tried, going back to kitkat and upgrading again, factory resetting from within lolipop, wiped caches, and such, and I just can't get it to work. Any ideas would be greatly appreciated. It can't be hardware related since calls work fine on kitkat right?
