iPhone 5 front glass panel separating/lifting away from body?

"Apple will replace the iPhone!

I had exactly the same problem this week with my iPhone 5, which is nearly 3 years old. It is out of contract.

It got very hot during charging while I was using it. I guess it's been doing this for awhile, but I had not noticed it before.

Then I noticed the upper left corner edge had lifted by a small amount. It seemed to get worse after another charge. I don't use an external case.

After checking websites, a faulty battery seemed likely. I took it to an Apple Store. They agreed, and a diagnostic test showed the battery was out of the green area.

Result: I received an instant replacement with a brand new iPhone 5! Guess upgrade will have to wait a bit."

Some iPhone 5 and 5C have a problem of battery swelling. The problem initially manifests as phone getting hot during charging which is generally ignored considering it normal. Subsequently screen detachment is seen in upper left or right corner which is pushed down by the user to fix it which seems to correct the issue initially but it continues to get more and more pronounced. It is also seen as a vertical streak when home button is pressed. All these signs are given a go-bye by the user not suspecting anything amiss. The screen starts to get detached more and more till it becomes non correctable. Those who can go to Apple store get a free replacement with no questions asked but they do not give any cause for this problem. Those who do not go to the store attempt screen replacement with no success because the actual problem is with the swelling battery which is least suspected. Changing the faulty battery in the first place is the solution. That is about it!

I think I'm a little late to the party here, but I recently noticed that on my iPhone 5C, the screen was coming out of the case in one corner. I dropped it on carpet the other day - not hard enough to do any damage - but I guess the case is flexible enough under pressure that the corner came off a little. Anyway, after reading the same problem on another forum, I put the phone face-down on my desk with a cloth under it to prevent scratching (I used a tshirt, but anything will do) and then applied pressure with my hand until it popped back in with a nice, loud pop. Worked great for me! Hope this helps you.

"Hi there was the screen every been changed?

Even if it hasent some times the plastic bezal with clips attached to the screen can break apart slightly this is because adesive has softend"

"Thanks to this thread, I took my 32 month old iPhone 5 with a separating screen to the Apple Store today for a Genius bar appointment. I assumed they would tell me it would require a screen or battery replacement and that it would not be covered under warranty.

The second the tech saw the screen, he said he knew it was a swollen battery that was causing the screen to separate. He explained that the enlarged battery places pressure on the back of the screen, causing it to shimmer with different colors when you press on the screen. He said that because it is a battery defect, it is covered for 36 months with the iPhone 5, and they don't attempt to repair them due to the potential for battery leakage and other damage it may have caused.

So I walked out with a brand new iPhone 5. Free replacement."
