iPhone 5 screen popped out - can't push back in
I noticed my iPhone 5 screen popped out in the bottom left corner a few weeks ago (it has never been dropped, not sure how this happened).
It's still functional, so I didn't do anything at that time. Now, the screen is slowly popping out a little more, where it is starting to affect my round home button, making it a little loose.
I can push the screen back down, but it just pops back up, and doesn't want to stay down.
I will have access to a 5-Point Pentalobe screwdriver next week, so I could try to remove the bottom screws to see if it will pop back in easier after I do that, but was wondering if anyone had any other suggestions.
My phone is no longer under warranty, so I can't swap it at the Apple Store without costing $$$.
I am attaching a few photos of the iphone to this thread.
Could this be due to a swollen battery? Has anyone else had this happen?
Thanks
