I was traveling by air very recently, and once I got home I noticed that the button on my iPhone 6 seemed to be more deeply recessed. After a while I realized that this did not make any sense mechanically, so I removed the Rhinoshield phone protector and discovered that the front of my phone was slightly pulled out!!
How this happened I do not know, but the timing seems to be related to my last trip through airport security; Hong Kong. However the phone is old and was opened several years ago for a screen repair, so I supposed it might have somehow spontaneously popped open.
I don't know if it was surreptitiously opened or not, but if so, why might this happen, and what if anything might have been done to it?
The poor quality photos are from my laptop. I have turned off the power of the phone right now for safety reasons.
