iPhone 12 keeps crashing/re springing
So I’ve noticed when I’m watching something on safari my iPhone crashes and it’s happened to me while just being on different apps whilst listening to music on the phone. I updated the phone from 14.1 to 14.4 and it still is happening. What happens is the screen goes black and has the spinning wheel in the middle of the screen for couple seconds and then the phone ends up on the Lock Screen.
Not sure what is the reason for this and not sure if there is an issue with the phone.
iPhone 12, iOS 14
