Fixing broken USB power port on Samsung Galaxy 6S Edge


Suddenly one day the USB cord won't stay in and the phone won't charge.  Closer inspection i can see the tab in the middle seems missing.  Must have broken off when i was carrying it around with the external battery plugged in.  Dang.  I can charge it wirelessly for a while but that is going to get really inconvenient in the car.  I didn't buy the damage warranty, and the phone isn't paid for yet, so I can't just get a new phone.  So I dive into make the repair.

The repair was a success after all, but yuck this is a terrible phone to repair.  Count on destroying the back if you ever want to open the phone.  It is made of glass and stuck to the back with adhesive. The upside is the USB port is easy to swap once the phone is open, only one ribbon cable needs to be unplugged and a minimum of disassembly.

Watched this:

Then I bought this:

It looks like this phone requires heating up to break the glue.  The video doesn't mention how to re-glue it.

I will update the blog when the part comes... parts here.   Started repair.  No photos because my phone is the patient in this repair.

Heated the phone back with my heat gun and used the temperature probe, this has the problem of the phone getting hot and hard to handle.    The clean opening in the youtube video was impossible to duplicate, the glass back cracked immediately when i began to pry on it with an opening tool.    I also left some small scratches on the frame, no biggie but i'm glad it is my phone not someone else's.   The phone back was completely shattered by the time I worked around it and loosened it from the frame.

Very glad I bought a replacement back before I started.  I bought because i thought i would need it for the adhesive.  Turns out I need it because the old one is shattered by removing it.

Here is what the back looked like after i pried it off.  Wow.   The USB board that was replaced is also shown.

This is the new back I bought




Pressed on the back of the battery and wiggled a bit and was able to remove the circuit board from the frame.   The big surprise was that the sim card needs to be pulled out of the top of the phone.  I never noticed there is a small cover on the top of the phone where the sim is inserted.  Duh didn't occur to me that this phone doesn't have the sim card inside.   Until the sim is out you can't take the circuit board all the way out of the frame.

Replaced the USB board without further dissembling the phone.  I could snap the ribbon onto the underside of the main board by just lifting it slightly.

The bad news is i can see i scratched the inductor on the back of the frame and broke a trace at the edge of the black square in the process of removing the back.  Arrgh.  Either wireless charging or NFC may not work now and i'll need to see if i can get that part.   Looks like it is readily available:

Meanwhile i will reassemble and test the phone...

Bingo, wireless charging is still working... i'm somewhat surprised because a trace was clearly broken on the very edge of the black patch containing the inductor.

Plugging in the USB i get the battery and it shows charging... so the new part worked.

Made a call, charged the phone, took pictures, everything seems to check out ok.  Hooray.

OK so we have a winner.   The phone is fixed.  I will have to see if the NFC works next time I'm at a store, it is possible it won't and i will have to open it again and replace the middle frame part with the NFC inductor in it.  When I do I will order another back because I'm sure this one will get broken opening it again.
