Chosen Solution

Hey Guys, so i had my IC chip replaced, and when the phone came back it is now very buggy. when i go to settings and try to choose wifi it freezes . To the point that i have to reboot. I’m getting Call failed errors while trying to dial out. 1 in 20 calls that i make go thru. signal goes from 4 bars to 0 in the same spot that my wife iPhone 6 plus phone stays at full bars. when rebooting phone it stays at the white apple screen for almost 3 minutes. tried to upgrade Firmware but i get the same problems. What do you think is happening or happened?

Sounds like you need to send it back. The only constant here is the fact that your IC was replaced. Something has gone wrong or wasnt done right with the repair.
