Samsung Galaxy Ace II x Display Digitizer Replacement

Received a damaged phone from a friend.

• The phone has a cracked display on the front.
• Necessary to replace the digitiser.

Replace the digitiser to fix the cracked display, no monetary reward is guaranteed or implied.

Identify the small hole on the left side of the phone, just below the volume rocker.

Use a fingernail to gently pry the battery casing open.

Locate the battery compartment.

• Pull up on the small dip at the bottom to release the battery.
• Slide the SIM card out of its enclosure.
• Alternatively, tap the phone against a surface with the display up to dislodge the battery.

• Remove the 8 highlighted screws.
• Push a spudger up to 1 cm into the device.
• Pry all around the outside of the phone where gray plastic meets display glass.

You may need to apply some force, but do not overdo it as this could damage the plastic or internal components.

Do not attempt to remove the motherboard yet.

• Locate and remove the single screw securing the motherboard.
• Leave the motherboard in place for now, further instructions will follow.

Locate the power button connector on the side of the device and gently spudge it off with a plastic tool.

• Gently disconnect the highlighted ribbon cable from the motherboard.

Do not pull the motherboard away from the display housing yet!

You do not need to disconnect the ribbon cable connecting the speaker and headphone jack assembly if you are only replacing the digitiser.

Locate the side of the display chassis without the white plastic covering.

• Lift this side gently to expose the ribbon cable connector.
• Use a plastic spudger to release the ribbon cable from its connection.
• With the ribbon cable disconnected, carefully remove the motherboard from the display chassis.

Disconnecting any camera modules first will make them easier to access later if needed.

The Thin Film Transistor housing is now exposed.

Flip the black tab on the ribbon cable upwards to the right.

Gently pull the ribbon cable out to disconnect it.

Caution: Excessive heat can damage screen components.

• Apply heat to the entire display front using a heat gun or hair dryer.
• Pry open the seam around the top right with a nail, then insert a spudger.
• Gently run the spudger along the display edge, avoiding sensitive areas like the silver speaker and home button.
• Release any separated digitiser surfaces from the metal TFT housing to prevent re-sticking.

• When using a spudger, always drag it towards the glass, not towards the metal body, to avoid scratching the TFT.

Carefully pull the ribbon cable connector through the slot.

Be cautious of snagging on parts.

If replacing the digitiser, proceed with usual care despite its resilience.

• To reassemble, reverse all steps mentioned above.
