My iPhone 13 pro max screen is just white it will not let me update or restore
At first my phone stopped responding to touch then it started randomly hitting buttons and sending texts. I had to force restart and it still wouldn't work. I then attempted to update phone when plugging into my computer. It stated there was a problem that occurred. Then my screen turned white, I then attempted to restore my iPhone and that was unsuccessful as well. Help I have exhausted all of my ideas.
iPhone 8 Plus, iOS 12
