Introduction

Prerequisite guide only! This guide is part of an another procedure and is not meant to be used alone.

This guide shows how to remove the clipped and screwed on plastic midframe for the pixel 3a.

    • Remove the fourteen T3 screws of the following lengths securing the plastic midframe:

    • Twelve 4.3 mm silver T3 screws

    • Two 4.3 mm black T3 screws

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.

    I found that a T3 bit didn’t get purchase on the screws in my Pixel 3a, but the T4 bit worked great. Not sure what’s up with that.

    This is definitely possible, depending on which kit’s T3 bit you use, along with potential screw quality variances.

    My Pixel 3a has been apart three times for a non-functioning front camera. The first time, it was by a Google authorized repair shop, and the camera stopped functioning again after a few months. When I took it apart the second time, I noted that many of the screws weren't seated before I removed them. The camera module had become disconnected and simply reseating the connector fixed it. I was careful to fully drive all screws and apply an appropriate amount of torque to them, thinking the repair shop failed to do so. After 9 or 10 months, my front camera stopped working again. Again, I'm noticing a lot of the screws have worked themselves loose. I'm going to try to find an appropriate thread compound that I can precisely apply to these tiny screws.

    Hey Reid,

    I would suggest blue Loctite or threadlocker. Dab a small drop on each screw before you install them.

    Arthur Shi -

    One of the bolts was rounded, so the torx screwdrivers (T3 or T5 in the kit) couldn't bite and loosen it. Not sure how to go forward.

    • The midframe is still held in place by plastic clips.

    • Insert an opening pick into frame seam at the bottom of the phone. This seam sits between the plastic midframe and the back cover.

    • Slide the pick along the seam to release the clips holding the plastic midframe.

    • Slide the opening pick along the left and right edges of the phone to release the midframe clips.

    • Lift the bottom edge of the plastic midframe up but do not remove the midframe. The midframe is still tethered to the phone by the fragile proximity sensor cable at the top edge.

    • To reinstall the plastic midframe, align the midframe to the back cover, and squeeze the perimeter of the phone with your fingers to snap the clips back into position.

    • Use the point of a spudger to carefully pry up and disconnect the proximity sensor connector from the motherboard.

    • Your proximity sensor connector may have automatically disconnected itself when you lifted the midframe.

    • Remove the plastic midframe.

    This connector is f*ckn impossible to reconnect 😭

    This is the hardest part of the job. I gave up on connecting the proximity sensor while in the midframe, and found it much easier to remove the proximity sensor from the midframe, attach the connector, then thread the sensor into its home in the midframe.

    • This step shows how to reconnect the proximity sensor during re-assembly.

    • Align the top edge of the plastic midframe with the phone.

    • Use the point of a spudger to carefully align and push the proximity sensor connector onto the motherboard socket.

    • This takes a bit of patience and finesse. Once you have the connector in place, you can also use a finger to gently press the connector onto the socket.

    • Alternatively, you can remove the proximity sensor from the midframe to reattach it to the motherboard first.

    • Use the point of a spudger to carefully pry the proximity sensor out of its recess on the midframe. The sensor is lightly adhered to the midframe.

    • Remove the sensor from the midframe. Attach the sensor connector onto its motherboard socket.

    • Thread the sensor cable through the midframe and reposition the sensor in the recess. Press down with your finger to adhere the sensor back onto the midframe.

    I tried to do this for about 15 minutes before I went to the alternative. There is a tiny post to hold the sensor in position on the midframe. I pried the sensor from the midframe from the corner opposite that post and then finished this step in 2 minutes.

    Definitely plan b for reconnecting the proximaty sensor…

    noel -

    Plan B ok for me as well. There is a hole below the sensor in order to push it with a sim card opener.

    Laurent GUILLOT -

    Definitely plan B

    Tom Heath -

    Plan B here as well. Also +1 for Laurent GUILLOT's hint.

Conclusion

To reassemble your device, follow these instructions in reverse order.
