Fortunately, the iPhone 5 family of smartphones are substantially less complex than the iPhone 4 series when it comes to repairing a broken screen. The amount of steps went down from 50 to 20 and the display screen can be easily be removed now.
Testing the phone should be done same as with the iPhone 4:
- Battery charging
- Digitizer working (Move an icon around display)
- Proximity sensor working (put fingers over sensor. Screen should go dark)
- All video
- All audio
Note:The iPhone 5 has three microphones. One is the front microphone which works with the front camera, another is the rear microphone, which works with the rear camera and then there is one at the bottom front for the audio recording. (voice memo usage, etc).
When the SIMM card is removed, (which is also done during testing), you should see a little white sticker in the slot. If it is pink or red, that would indicate water damage.
Shut off Phone
The first step to removing the required components of course is to shut off the phone. If the digitizer is not working, then you can shut down the phone by pressing the Home and Power button simultaneously and the phone will shut down.
Then remove the two Pentalobe screws that are next to the dock port. Same as with the iPhone 4.
New to this procedure is that the manner in which the display will disconnect.
Removing the Cover
Use a suction cup to gently lift the cover slightly to about 30 degrees. DO NOT LIFT THE COVER ALL THE WAY. There are additional components that are still connnected to the logic board and the cover. Removing the cover all the way will cause the components that are still attached to break off.
Note that the logic board need not be disconnected.
Removing the Battery
- This is also standard procedure, but the manner in which the battery is removed is done differently. There are two top silver plates covering the battery connector, connected by three screws, but only the bottom plate needs to be removed in order to get to the battery connector. Remove the two screws securing the bottom metal battery plate. Use a plastic opening tool to gently pry the battery connector up from its socket off the logic board.
Remove the EMI Shield
There is a plate that covers the front camera cable, the LCD cable and the digitizer connector cables. This is called the retaining EMI shield plate. All these three cables are still connected to the cover.
The EMI shield is located at the top right of the phone.
Note: One of the screws tends to not be attracted to a magnetized screwdriver. Take care not to lose it when removing, and make sure it gets back into the right place—a magnetized screw may interfere with the compass.
There are four screws that hold the plate. The screw on the upper right corner tends to not be attracted to a magnetized screwdriver and this is because it is near the compus, so by making it non magnetic will not interfere with the compus and its components. This is also the longest screw of the four and this screw must be placed right back in the same location. Once this is done, the front panel assembly cover can be removed.
Under this plate are the front camera connector, which is also the connection to the ear speaker, upper microphone, the proximity sensor. Also, under the EMI shield is the LCD cable and the digitizer cable. These components connect to the cover, so once they are disconnected from the logic board, the cover can be safely removed.
Once the plate is removed, disconnect the front camera connector, the LCD cable and the digitizer cable from the logic board and the cover will come right off..
Identifying Components from the Old Display Cover and Place on the New Display Cover
The following components need to be taken off the old display:
At the Top:
- Ear Speaker
- Ear Speaker Bracket
- Front Facing Camera Cable
- ONLY ON IPHONE 5 BLACK SCREENS. Ambient light filter (ambient light is the light that is reflected on to the phone within the environment it is in). This piece is immediately placed onto the new screen cover, so as not to loose it.
At the Bottom:
- Home Button Flex Cable
- Home Button Bracket
- Thermal Plate
IV: Display Component Dis-assembly
- On Top of Phone
- Remove Ear Speaker Bracket
- Remove Ear Speaker
- Remove the ear speaker cable, ambient light sensor, proximity cable, upper microphone and connections for the ear speaker. All are part of one main cable that comes off the display.
Note: There are three very small components that must come off. They are the black plastic cover over the ear speaker, the rubber boot gasket, just under the ear speaker that covers the light sensor and, FOR BLACK SCREENS ONLY, the silver filter over the light sensor (after the rubber boot is removed).
- Remove the black ear speaker cover
- Remove the black rubber boot
- FOR BLACK SCREENS ONLY: Remove the silver filter by using a flat head screwdriver and slightly twisting. Immediately place onto the new display.
- Remove the transparent front facing camera ring that is located over the camera.
- Bottom of Phone
- Remove the home button bracket and cable (connected together)
Note: There are two yellow adhesive stickers that come off that allow the the bracket and cable to be removed. Carefully remove these adhesive stickers.
3. Remove the home button by pushing the underside of the button outward. Immediately place onto the new display.
NOTE: Take every precaution NOT damage the home button/fingerprint scanner cable. The fingerprint ID scanner is locked to its original iPhone, meaning this CAN NOT be replaced. The home button will function, but the fingerprint scan will never function again.
- Remove Thermal Plate
There are six screws connecting the thermal plate
- Unscrew and remove thermal plate
- Remove plastic cover from new thermal plate
- Immediately place onto the new display
