If your Samsung Galaxy S10, S9, S8 or other Samsung phone won’t charge, has a loose charger, or its charging cable falls out of its mini-USB charging port, chances are pocket lint is the culprit. Many smartphone users carry their phones in their pockets, and over time lint works its way into the USB charging port and prevents the charging cable from making a solid connection with the port contacts. In addition, USB cable jacks have small hooks that interlock with the charging port, and lint can also make it impossible for these hooks to properly latch. Fortunately, it’s easy to repair the USB charging port on Samsung phones. Here’s how to do it, plus how to replace your Samsung phone’s charging port if lint isn’t the problem.
How to repair the USB charging port on a Samsung phone
The following steps detail how to repair the USB charging port on a Samsung phone, regardless of the model you have (Galaxy S10, Galaxy S7, etc.):
1. Turn off your Samsung phone and disconnect it from the charger
2. Look into the charging port; you’ll notice the small card containing the contacts the charger connects to
3. Insert a small needle into the charging port and slowly, gently swipe it through the space between the contact card and the USB port walls
4. As you swipe, gently pull the needle toward you and out of the port to remove lint
5. Continue swiping the needle around the port until all the lint is removed
6. Now, your charging cable should latch properly and your contacts should make solid connections in the charging port. Your Samsung phone should charge normally
How to replace your Samsung phone’s charging port
You can replace your own Samsung phone charging port, mail it in for replacement or take it to a local repair shop. Professional repair runs between $70 and $100, depending on which model you have.
