How to Replace the Samsung S20 Charging Port PCB Board

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.

Called the German Valentino, designer Guido Maris Kretchmer’s fall-winter designs showed his passion for design and fabric. From an early age, his fashion career blossomed when he received his first sewing machine. Within a short amount of time, Kretschner became one of the most successful designers in Germany. His looks are unique, exciting and stylish.

His versatility is reflected in both of his collections. For his premium line, he designs high-quality cocktail dresses and glamorous evening gowns. The Guido Maria Kretshmer collection focuses mainly on ready-to-wear looks and business looks. His clothes are worn by such stars as Charlize Theron, Christine Neubauer and Alexandra Maria Lara. Several models trust his fashion expertise, and they love to wear his clothes on the red carpet.

The designer has also published two bestselling books, and his designs were spotlighted in a documentary that aired on the German TV channel VOX.

Another designer to watch, Hernan Lander showed a great fashion collection at the European shows. With an innate desire to push boundaries, Lander employs visions of modern art and innovative forms of architecture in his collection. His journey began in the Dominican Republic at Altos de Chavon. His contemporary designs were extremely elegant.

Paul Nathapol’s collection was inspired by the 1950s philosophy movement and existentialism, where one’s freedom to express the individual experience is explored. His designs emphasized the uniqueness and isolation of these experiences and how they play such an important role in one’s existence.
