Welcome to my blog phone parts

The Samsung Galaxy S20 charging port is combined in a module of PCB board. It can be swappable if the charging port is broken. To replace the charging port PCB board, we have to tear down the back housing, take off the wireless charging port, and the loudspeaker bracket as well. Here are the specific steps Etrade Supply would like to show you blow.


1. Tear down the Samsung S20 back housing and take off the wireless charging coil

Firstly, we need to tear down the back housing. Power off the phone and take out the SIM card tray. Use a hot air gun to blow on the edge and corners of the back housing. Use a suction cup to pull and an ultra-thin plastic panel to slice and separate the back housing. Flip and remove it away after it is separated. Unbolt the eleven screws for fixing the wireless charging coil, disconnect the BTB interface cable. Pry and take off the charging coil with a steel prying tool. Just be careful and don’t break the flex.

2. Take off the bottom loudspeaker bracket and replace the charging port PCB board

Loosen the five screws for fixing the bottom loudspeaker bracket. Take off the bracket slowly. Disconnect the battery flex cable, the SUB mother board flex and the antenna flex with a spudger. Take off the flexes from the phone. Undo the five screws for fixing the Samsung S20 charging port PCB board, then we are able to take off the board. Use the steel prying tool to pry out and take off the charging port PCB board. Install the new PCB board into the phone, fixing it with the five screws.

3. Assemble the Samsung S20 phone and test the new replaced charging port

Connect the SUB mainboard flex and the antenna flex back. Assemble the bottom loudspeaker bracket back, and fix it with the five screws. Connect the battery flex cable after that. Install the wireless charging coil back and fixing it with the eleven screws. Assemble the back housing to the phone. Gently press on the back to seal up the phone. Insert the Samsung S20 SIM card tray back. Turn on the phone and plug the USB charger to check if the charging port is normal.


The whole process above may be a little complicated for a new repair beginner. Besides, we should be careful on slicing and tearing down the back housing because it is easy to be broken. There are many flex cables inside, don’t misconnect the cables. What’s more, Etrade Supply offers new replacement parts for Samsung Galaxy S20 repair.
