A Public Service Announcement
The screen on my iPhone 6 had detached from the body of my phone on one side. I thought this was a problem with the body of the phone being slightly warped and stress used to keep the screen in place exceeding the ability for the screen to snap back into place.
As it turns out, the real problem was a swollen battery. This is bad. As in “the phone explodes into a fiery fire-ball” bad. You should get your device fixed in that case.
This has been a public service announcement.
