iPhone 7 Plus shut off and won't turn back on
My phone randomly shut off, but not completely. It is stuck on the loading symbol. I tried force restarting it and it will not do anything. I've also tried connecting to iTunes on my computer, but also cannot do anything because I need my phone to be on. It has been on the charger for more than an hour already. Nothing is working.. Has anyone had this problem? If so, how did you fix it? Help.
iPhone 7 Plus, iOS 10.3.2, null
