Hello everyone. A friend of mine's iPhone 6S suddenly stopped working Wednesday morning, with the phone not booting past the Apple logo, without a colored screen appearing very quickly, and shutting off. I told her how to update her phone from iTunes to fix the issue, and it worked, with her data still on her phone. But the issue got worse. I assume it is because iOS 10.3.3 has a lot of issues, but this is too much. Almost all of her apps don't run without crashing right after, except the App Store, Settings (although it hangs and freezes sometimes, Settings works), and certain apps that were updated after fixing the first issue. Sometimes, even the home menu crashes when trying to delete an app. After a while, the phone was able to successfully delete some apps, but with the phone connected to a computer or not, the apps would reappear after reboot with most of them having a blank icon. Running them still crashes. Deleting them from the Home Screen, Settings, or iTunes doesn't matter, because they reappear anyway. While we were trying to diagnose this issue, a new glitch literally just appeared, on the lock screen. The image provided shows what her lock screen looks like. I'm starting to think that these glitches isn't just the latest iOS update. Any help to fix all of these issues would be appreciated. Thank you
Recap: main issues are: apps don't uninstall, they reappear, apps crash all the time, and some areas have graphical issues
