This guide will show you how to replace the charging port of your Motorola Moto G 3rd Generation. The repair is fast and simple but may require a heat gun.

  1. Use your fingernail to pry under the notch on the bottom of the phone and remove the back cover. Make sure to fully power off the phone before you begin disassembly.
    • Use your fingernail to pry under the notch on the bottom of the phone and remove the back cover.

    • Make sure to fully power off the phone before you begin disassembly.

    This repair is much, much more difficult than it appears. The LCD connection and the battery connection are borderline impossible. Everything else is simple or nearly simple. The glue is about a tenth as tough as Samsung phones.

  2. Use a heat gun or an iOpener as a heating tool. This guide explains how to use the iOpener. Evenly apply heat to the edges of the touchscreen to loosen the adhesive.  Continue to Step 3 once the edge of the screen is warm to the touch.

    • Evenly apply heat to the edges of the touchscreen to loosen the adhesive. Continue to Step 3 once the edge of the screen is warm to the touch.

    • Do not let the iOpener/heat gun remain on one spot for too long. Excess heat can damage the phone.

    • When reassembling the phone, use the iOpener/heat gun to help the adhesive fuse to the new screen. Heat the screen edges, apply pressure to the screen, and hold the screen in place until it is secure.

    I kept my phone on the radiator for 10min and loosened it enough to open (felt safer than a heat gun).

  3. As the adhesive loosens, pry up an edge of the screen with a plastic opening tool or an opening pick.  A suction cup may also be useful here. Use an opening pick to hold that edge in place and continue this process around the entire screen, applying more heat as necessary. Avoid damaging the LCD screen connector while prying along the screen edges.  It is located on the left edge of the phone, across from the volume controls.

    You may need to remove the mouthpiece and earpiece gauzes from the screen to fit to the replacement screen

    Be careful not to damage the adhesive tape on the old screen as you may need to reuse it along with the two gauzes on the replacement screen

    which adhesive tape?

    MotoG Fan -

    What width of adhesive is appropriate to buy to replace the existing one? I can see 1mm, 2mm etc for sale

    Avi Silver - Yanıt

    The width of the adhesive tape that goes around the rim is 2mm. But rather than buying generic 2mm tape, which won't seal well at the corners because it would be bent pretty sharply, it's best to get a precut adhesive that is made for this specific phone and that comes with the corners (and everything else) already pre-shaped: it's cut into a phone-shaped sheet, most of which you'll be discarding. Such sheets are available on ebay.

    I did not need to use any new adhesive strips to get my screen securely back in place. After placing the screen back, just heat the edges of the phone as before and press tightly (though not too hard, of course) until cooled.

    • Use a plastic opening tool to flip up the lock on the display cable ZIF connector.

    • Pull the display cable from its socket on the motherboard.

    • When installing a new display, carefully remove all remaining adhesive from the phone, and clean the adhered areas with isopropyl alcohol (90% or greater) and a lint-free cloth. Install the display using pre-cut adhesive or a strong double-sided tape such as Tesa 61395. Turn your phone on and test your repair before sealing the display in place.

    This part was actually the trickiest of the whole (replacing battery) process. Putting it back together here is tough… well would have been better had I not left my glasses in work.

    [English below]

    Wer das Gerät während des Displaywechsels eingeschaltet lässt, sollte es dennoch einmal neustarten, wenn es fest verklebt wurde. Wie ich auf die harte Tour herausfand, kalibriert sich der Annäherungssensor erst bei einem Neustart neu und geht nach einem Wechsel (Display abgenommen = niedrigerer Wert) davon aus, dass das Handy dauerhaft in der Tasche/am Ohr ist.

    Ein kurzer Neustart verschafft Abhilfe.

    .

    [English]

    For those not powering off the device while changing the display (i.e. to test the functionality) I recommend to restart the device after the repair is done and the display is glued in.

    As I found out the hard way, the proximity sensor recalibrates at the restart and without the display it sets lower values as a minimum (since there are no obstacles in the way). After the display change it will think that the phone is in your pocket or at your ear all the time.

    A restart solves that problem.

    I am using a Moto G3 phone as my backup phone and it’s screen is cracked but it is working fine. After watching your video I removed the screen carefully, bought a new digitized screen and fixed it. Now I am in a big trouble because the touch pad doesn't work. Even I couldn't switch off it. I complained the seller and he gave me another screen thinking the previous is having an issue. Unfortunately after fixing it the problem remains. How to solve the touch pad issue please?

    I agree this is extremely tough, to take off or put on. Taking it off is hard enough ( the lever is tiny and opens up). Connecting it back up is tough because the position is so awkward.

    Replacing this battery connection is the single hardest connection I have done on any phone or laptop in my experience! The border walls break very easily and the connection itself breaks off the board very easily. I am still not sure how to slide the plug into place without breaking off a border wall.

Is all this necessary? There is a youtube teardown that states the usb port should be replaceable from just the 3 screws, so no glue gun, no screen removal etc. So just step 9.

So is this repair accurate?

Brendan L - Yanıt

Step 10 tells you to push out the charging port from inside the case, which would require first removing the screen. Maybe it's possible to just remove the charging port from outside the case like in the video, but it may require a lot of force and pushing it out from inside is just easier.

Ahnaf Siddiqui -

I mean I replace my charging port every 6 months now and I the only thing I do is unscrew the charging port area and get a tiny flathead bit after applying heat and pull off the metal plate. After that, I insert the flathead into the bottom of the charging port from where it plugs and push it outwards.

nikomarquez2013 -

Facing exactly the same issue as Hamed Khan.

@Hamed - Do you know how to fix this? Or have you received any tips. If yes, please forward me too. BTW, a technician told me that this could be the problem with the mother board but I don't trust him.

Sudhir Bhavekar -

Facing same problem, please please let me know who to fix it?

sadiquehannure -

@hamed Khan have you found any solution, I am facing same problem, don't know the problem is about charging port or motherboard, please help me , let me know what you did with your phones problem.

Prasad Mande -

hello,

does your phone shows charging symbol even it is not connected with charger?

just let your battery drain to zero percent.

don't charge your phone till 1 hour.

try to start your phone with empty battery..

it will show a symbol to connect charger,,

then connect the charger.

hope this solves your problem...

hamed khan - Yanıt

same problem for me like strange issue. Please give the solution

chandutangudu - Yanıt

Too many unnecessary steps in this guide. Every guide I've found has the whole phone coming apart, but you don't need to do any of that. I changed the port last night in less than 7 minutes.

Pulled the little door off then briefly ran a heat gun over the metal plate on the USB board to loosen adhesive

Using a thin flathead micro-driver and a dental pick, I pulled the board off the back in less than 5 minutes. Put the new one in after migrating the metal plate and some of the adhesive and it worked great.

Thanks for the instructions! they were super helpful!

Joseph Olsson - Yanıt

Hi, I didn't want to dismantle the whole phone, and tried to look for an alternative.

I found this video: https://www.youtube.com/watch?v=wkTd_nsD...

which just removes the back cover, three screws, heats the piece and takes it out ready to be replaced.

It took me 10min.

Alvaro Perez - Yanıt

Just change the port and the will solve the problem..!! Coz faulty capacitor on the port pcb sometimes cause this problem!!
