Step-by-Step Google Pixel 4a 5G Rear Camera Replacement

Step 1: Prepare the Phone and Tools

Start by gathering the required tools and the replacement rear camera unit.

Having everything ready before opening the phone will make the repair process easier to manage and help keep the removed components organized.

---

Step 2: Heat and Remove the LCD Screen

The repair begins with removing the LCD screen from the front of the Google Pixel 4a 5G.

Important: Heat the screen gently around its edges until the adhesive becomes soft. Avoid applying excessive heat.

For this repair, place the phone with the front screen side on a heating pad and select the mobile phone heating option. Allow the heating process to complete. A heat gun or hairdryer can be used as an alternative.

Once the adhesive has softened, use a suction cup to lift the screen slightly. Insert a plastic card pry tool or a similar tool around the edges to cut through the adhesive.

Isopropyl alcohol can also be used around the screen edges to help dissolve the glue. Work carefully around the display and gradually separate it from the body.

Lift the screen gradually to approximately a 90-degree angle from the top. Use tweezers to pull out the LCD connector bracket, then disconnect the LCD connector to completely free the screen from the phone.

---

Step 3: Eject the SIM Tray

Before continuing with the internal disassembly, eject the SIM tray from the Google Pixel 4a 5G.

Keep it in a safe place so it can be reinstalled later.

---

Step 4: Remove the Mid-Frame Screws

Remove the nine screws securing the mid-frame plate.

Keep the screws organized so they are available when the mid-frame is reinstalled.

---

Step 5: Separate the Mid-Frame from the Housing

Use a plastic card pry tool or triangle picker between the back housing and the mid-frame plate.

Run the tool through the gap to release the clips holding the two sections together.

Important: Be gentle around the flex cables when separating the back cover housing. Avoid pulling or putting unnecessary pressure on them.

Once separated, place the back cover on a suitable surface and carefully position the mid-frame body on the housing. Do not force the phone or its cables during this process.

---

Step 6: Remove the Logic Board Bracket

Remove the logic board bracket by undoing its seven screws.

Once the screws are removed, take out the bracket and set it aside for reinstallation.

---

Step 7: Disconnect the Battery and Sensor Plugs

Disconnect the battery plug from the board.

Next, disconnect the fingerprint button and flash sensor plugs from the board. These connections need to be released so the back cover can be separated from the body.

Handle the plugs and their cables carefully during removal.

---

Step 8: Remove the Front Camera and Headphone Jack

Disconnect and remove the front camera.

Then disconnect and remove the headphone jack. Keep both components safely aside because they will be installed again during reassembly.

---

Step 9: Remove the Speaker and Antenna Board

Remove the speaker by undoing its three screws and loosening the adhesive.

Important: The antenna board may still be attached to the speaker. Pull the speaker carefully, separate the antenna board, and then remove the speaker.

Next, disconnect the antenna board plug from the logic board.

---

Step 10: Remove the Logic Board

With the surrounding components disconnected, gently lift the logic board from the phone.

Important: Be careful with the flex cables while lifting the board. Avoid pulling or applying unnecessary force.

The rear camera can now be accessed for replacement.

---

Step 11: Remove the Faulty Rear Camera Unit

Before removing the camera, apply heat to soften the adhesive underneath the camera.

Once the adhesive has softened, carefully pry the non-working 2-in-1 rear camera unit away from the body.

Work gently during this process to avoid putting unnecessary pressure on the surrounding components.

---

Step 12: Install the New Rear Camera Unit

Place the new Google Pixel 4a 5G 2-in-1 rear camera unit onto the body.

Position the replacement camera correctly before continuing with the reassembly.

---

Step 13: Reinstall the Logic Board

Gently place and secure the logic board back onto the phone body.

Make sure the board is positioned correctly before reconnecting the surrounding components.

---

Step 14: Reconnect the Antenna Board

Reconnect the antenna board plug to the logic board.

Make sure the connection is properly secured before continuing.

---

Step 15: Reinstall the Speaker and Antenna Board

Return the speaker and antenna board to their original position.

Secure the assembly using the three screws removed earlier.

---

Step 16: Reinstall the Headphone Jack and Front Camera

Secure the headphone jack back into position.

Next, reconnect the front camera.

Both components should be returned to their original positions before continuing with the remaining reassembly.

---

Step 17: Reconnect the Fingerprint and Sensor Plugs

Maintain the back housing at approximately a 90-degree position.

Reconnect the fingerprint button and flash sensor plugs to the board.

Handle these connections carefully while bringing the housing and internal assembly back together.

---

Step 18: Reconnect the Battery

Reconnect and secure the battery plug to the board.

Once the battery connection is restored, continue with the logic board bracket.

---

Step 19: Reinstall the Logic Board Bracket

Place the logic board bracket back into position.

Secure it using the seven screws removed during disassembly.

---

Step 20: Reinstall the Mid-Frame

Starting from the top, gently slide the mid-frame body onto the housing and continue toward the bottom.

Important: Do not force the frame into place. Once it is correctly aligned, gently press it to fasten the clips between the body and housing.

---

Step 21: Reinstall the SIM Tray and Mid-Frame Screws

Insert the SIM tray back into the phone.

Then secure the mid-frame plate using the nine screws removed earlier.

Make sure the frame is seated correctly before moving on to the LCD installation.

---

Step 22: Reconnect the LCD Screen

Place and connect the LCD screen plug.

Reinstall the LCD connector bracket to secure the connection.

Before permanently installing the screen, the phone can now be turned on for verification and testing.

---

Step 23: Test the Rear Camera and Device

Turn on the Google Pixel 4a 5G and verify that the device is functioning correctly.

Important: Test the rear camera before permanently sealing the LCD screen. This allows you to verify the camera replacement before completing the final installation.

---

Step 24: Prepare the LCD Adhesive

Before reinstalling the LCD screen, check whether there is enough adhesive remaining around the display.

If additional adhesive is needed, use B7000 glue or new double-sided LCD adhesive as described in the repair procedure.

---

Step 25: Reinstall and Secure the LCD Screen

Gently slide the LCD screen into position, starting from the bottom and then moving toward the top.

Apply slight pressure around the screen edges to help secure it to the body.

Finally, use bonding clips to fasten the LCD screen in place. Leave the clips on for some time before removing them.

If bonding clips are not available, rubber bands can be used to tighten the screen against the body while the adhesive sets.
