My iPhone won’t turn on
I just woke up this morning to my iPhone not turning on and having 2 small horizontal green lines on top around the top bar. It was fine the night before. I’ve tried pressing and holding every button but it just won’t turn on and I’m just faced with a black screen everytime,not even the apple logo comes on the screen. What should I do, I don’t think I saved my information and I’m scared I’ll lose everything.
