Samsung A3 A310F A310 A5 A510 A510F 2016 A7 A710 A710F Micro USB Charging Port Dock Connector

This Samsung A3 charging port flex connector replaces the Micro USB socket on several Samsung Galaxy A series phones. If your phone does not charge, only charges at an angle or loses connection when you move the cable, this dock connector can help you fix the problem without buying a new handset.

Micro USB Charging Port Dock Connector

The charging socket sits at the bottom of the phone and takes the USB cable for charging and data transfer. With daily use, dust, moisture and knocks can damage the pins or loosen the connection on the board. When this happens, the phone may stop charging, charge very slowly or fail to connect to a computer. Fitting a new dock connector flex brings back a solid, reliable charging point.

Compatible Samsung Galaxy Models

This replacement Micro USB charging port is suitable for the following 2015–2016 Galaxy A series models:

• Samsung Galaxy A3 2016 – A310 / A310F
• Samsung Galaxy A3 2017 – A320 series (check board layout)
• Samsung Galaxy A5 2016 – A510 / A510F
• Samsung Galaxy A5 2017 – A520 series (check part number)
• Samsung Galaxy A7 2016 – A710 / A710F

Always check your exact model number (for example A310F, A510F or A710F) in the phone settings or on the original box before you order.

Fix Charging and Connection Issues

After you install this dock connector flex, you can:

• Restore stable charging with a Micro USB cable
• Reduce loose or wobbly cable connections
• Improve data connection to a computer or laptop

This part is ideal if your Galaxy A series phone only charges in certain positions, stops charging at random or shows no response when you plug in the charger.
