iOS 12.3 freezing and crashing iPhone 6s
I have an iPhone 6s and an SE the 6s is freezing randomly after update and was just serviced by apple on 5-18-19 with new battery. Freezing after leaving FaceTime to the point of reboot each time. Freezing during YouTube and lagging audio behind from Bluetooth connections ( lips don’t synchronize with audio output from Bluetooth in videos from YouTube and from Tv app
