Apple iPhone speaker replacement procedure – Apple iPhone 6 Earpiece Speaker removal and replacement Apple iPhone 6

Disassembling procedure 

Power off your iPhone before beginning disassembly. Remove the two 3.6 mm Pentalobe screws next to the Lightning connector.

The next three steps demonstrate using the iSclack, a great tool for safely opening the iPhone 6 that we recommend for anyone doing more than one repair. If you aren't using the iSclack, skip to Step 5. If the plastic depth gauge is attached at the center of the iSclack, remove it now it's not needed for larger phones like the iPhone 6. Close the handle on the iSclack, opening the suction-cup jaws.

Place the bottom of your iPhone in between the suction cups. Position the iSclack's upper suction cup against the display, just above (but not covering) the home button.

Open the handles to close the jaws of the iSclack. Center the suction cups and press them firmly onto the top and bottom of the iPhone

Hold onto your iPhone securely and close the handle of the iSclack to separate the suction cups, pulling the front panel up from the rear case. The iSclack is designed to safely open your iPhone just enough to separate the pieces, but not enough to damage the display cables. Peel the two suction cups off your iPhone.

If you don't have an iSclack, use a single suction cup to lift the front panel: Press a suction cup onto the screen, just above the home button.

Be sure the cup is pressed securely onto the screen to get a tight seal.

While holding the iPhone down with one hand, pull up on the suction cup to slightly separate the front panel assembly from the rear case. Take your time and apply firm, constant force. The display assembly is a much tighter fit than most devices.
Using a plastic opening tool, begin to gently pry the rear case down, away from the display assembly, while continuing to pull up with the suction cup. There are several clips holding the front panel assembly to the rear case, so you may need to use a combination of the suction cup and plastic opening tool to free the front panel assembly.

Pull the plastic nub to release the vacuum seal on the suction cup. Remove the suction cup from the display assembly.

Pull the home button end of the front panel assembly away from the rear case, using the top of the phone as a hinge.

Keep the front panel supported at a 90º angle in relation to the rear case until you remove it allowing it to fall flat will strain the display cables and their connections on the logic board

Several clips along the top edge of the front panel form a partial hinge, allowing the front panel assembly to swing open like a book. During reassembly, align the clips just below the top edge of the rear case. Then, slide the ront panel upward until its top edge is flush with that of the rear case.

Remove the following five Phillips screws securing the front panel assembly cable bracket:

Three 1.2 mm screws

 One 1.7 mm screw
One 3.1 mm screw

Remove the front panel assembly cable bracket from the logic board.

In the next four steps, take care to pry up only on the cable connectors, and not on their sockets on the logic board. Use the flat end of a spudger to disconnect the front-facing camera and sensor cable connector.

Use the flat end of a spudger to disconnect the home button cable connector.

Use the flat end of a spudger to disconnect the display data cable connector. When reassembling your phone, the display data cable may pop off its connector. This can result in white lines or a blank screen when powering your phone back on. If that happens, simply reconnect the cable and power cycle your phone. The best way to power cycle your phone is to disconnect and reconnect the battery connector.

Use the flat end of a spudger to disconnect the digitizer cable connector.

Remove the front panel assembly from the rear case.

Remove the following Phillips #00 screws from the earpiece speaker/front-facing camera bracket:
One 2.3 mm screw
One 3.0 mm screw
One 2.2 mm screw

Remove the earpiece speaker/front-facing camera bracket from the front panel.

Lift the front-facing camera out of its recess in the front panel.

Holding the front-facing camera out of the way, remove the earpiece speaker from the front panel. Be careful not to touch any of the contacts on the speaker or the cable, oils can damage them and interrupt the connection.
