glass not flush after screen replacement

Hi,

I have taken apart this iphone 3 times already, every time i put it together the screen is slightly raised

this causes problems,the glass is not flush and neither is the home button. If I press the glass down to make it flush, you can see bruises on the lcd.

I bought this replacement off of ebay. Could it be a faulty screen?

I followed directions to THE KEY. I do this stuff for a living so I dont see anything wrong

I have everything taken apart in front of me trying to see what causing the misaligment but I am completely stumped

It feels like it is too thick or something, like its not the correct fit

I'm having a very similar issue. I replaced my iPhone 4's LCD/front panel earlier this evening, because the original one cracked.

After installing the new display and re-assembling the phone, I noticed that the home-button felt a bit more sunken in, than before (my guess, by as much as a millimeter).

So I took the phone apart once again, to check whether I had not fully pressed the new display into place, before tightening the screws. But everything looked like it was as far in as it could go. So I again re-assembled the device, to no avail. It almost feels like the glass itself is thicker or something...

Is there a way to fix this, or perhaps place something under the home button to slightly raise it? My concern is that over time, the moisture from fingers and general use, would seep in through a gap (if there is any), when the button is pressed down.

I too have an LCD bruising concern when pressing on the front glass towards the top of the unit. I disassembled and cleaned all parts twice for quality control. During reassembly I paid close attention to the concern area. Still noticing some slight bruising on the LCD after reassembly.

During my initial teardown I noticed that the individual I purchased the damaged iPhone from had been nosing around the guts, ergo: missing and loose screws etc. I also noticed that this person tried prying the front display and bezel away from the midframe using what ever they could find -- most likely a small screw driver.

  • It's possible the previous owner slightly warped the midframe assembly during their attempt to separate the front display and bezel from the midframe.

Conclusion: in my particular case the LCD bruising is being caused by air gaps between the front display bezel and the midframe -- because the gap tolerance is almost infinitesimal and there is no visible obstructions preventing the front display bezel from seating flush to the midframe -- adhesive will most likely correct the concern

For everyone else experiencing an LCD bruising concern.

  1. Always prior to reassembly clean and inspect your parts.
  2. As stated above make sure there is no debris stuck or gummed up where the front display bezel and midframe meet.
  3. Use Rubbing alcohol 70% "it's in your medicine cabinet" and a foam Q-tip -- not cotton to clean and degrease with.

Side Note: In the iPhone 4 repair guide it calls out using Windex to clean and degrease wi-fi antenna components and other parts, . . . don't use Windex because there are additives that could leave behind a potential film or residue in certain ares. Rubbing alcohol evaporates on contact and is all one needs to clean and/or sterilize conductivity "metal to metal" components.

One idea is to shim the button so it is high enough to sit flush against the glass.

I had the same problem on an iPhone 4G that I bought on eBay. Seller indicated that he had replaced the screen with an OEM part. However when it arrived, it had the same wobbly button as Ricardo described.

So what I did was place some material between the button flex cable and where the button sits on the frame of the phone. You'll have to experiment with the thickness of the material. If it is too thick, it will engage the button as always on. I used a business card that was made from thin plastic. It was thin enough where I needed to stack two of them. Just cut it to size and put the screen back on. No need for any adhesive.

I originally thought that the shim would do something to restrict the button's operation, but it's not the case. Once I put it back together, it's been sitting flush and working fine. I was actually pretty surprised that it worked so well. :)

Hope that helps.

Depending on what manufacturer this person from eBay receives their parts from will replicate the part quality. If it is a copy/aftermarket part then you have to expect faults like this. When the part was manufactured the glass was probably moulded incorrectly therefore giving you a raised screen that does not sit properly.

Only way to fix this is to find a good supplier that you know will give you a good part (original/known good parts). I haven't heard any bad reviews from parts shipped by iFixit so they are worth a shot :)

Regarding your current screen, i would recommend to send back to them for a refund and take pictures as evidence.

Hope this helps :)

Look for a glass fragment left behind by the original stuck to the adhesive at either the top or bottom end of the frame. I buy the cheapest ones I can find and they fit very good.

iPhone 4 (GSM/AT&T) Screen

looking at this part description makes me wonder if you bought the lcd seperately from the glass?

"This part contains all the necessary components to replace the front display assembly. It is a complete part with the LCD and the glass fused together. It includes the speaker grill installed.

This is an Apple OEM part not a copy or imitation.

The glass and the LCD cannot be replaced individually as they are inseparable. Don't believe the other companies that try to sell you them separately."

I had followed the instructions to the key

I had bought it off of ebay, the right product glass and screen fused

My guess is that it was a bad imitation followed instructions perfectly and glass was raised above the frame everytime

sending this back to the person I got it from and getting one from here

Just got a cheapo part from Ebay, never again, I had this problem before I realised it came without the plastic/rubber part that goes between the screen and the steel mid-casing, I suppose they assumed I could reuse the old one, but it was melted in a couple of places :(

Lesson Learned!

Did you use adhesive? Some people skip this thinking screws are only needed, but the adhesive helps with the home button issue (new adhesive). Otherwise check the plastic frame to make sure it is fitted properly. If neither of these then it's just a manufacturing difference that you have to live with or buy oem.

Andrew, I was thinking to do what you explained, but I would not have actually tried if I had not read your comment. Thanks!

I bought LCDs from four different suppliers and all of them had the same problem with the home button staying a little low, but now it feels works perfect with your solution.

same thing happened to me. if you didn't buy the replacement screen from apple then other manufactures sometimes make the glass thicker for strength. for the problem with the home button its because the screen is thicker and if you didn't receive a home button with your purchase then the home button is slightly thinner than the screen making it feel more in depth. i hope this helps you
