Clean Galaxy A50 charging port

A dirty charging port may block or affect charging and data transfer functionalities on a Galaxy A50. As an end-user, the only thing that you can do is to check if there’s dirt or a foreign object blocking the charging cable. Try to check the charging port in a well-lighted environment and examine its charging port. If there’s a visible port or lint inside but no moisture, you can try compressed air to take them out. Do not stick anything inside to remove dirt as that might damage the system.

Simple Reboot or Forced reboot

Well, I think you already know how to restart your phone. So just restart the device and see whether it solves the issue or not. Restarting a device is always the ultimate solution for any issue. Not only Pixel but this applies to each and every electronic device. I used to tell my mom to restart her device if she faces any issue with her smartphone.

Well if you still need to know how to restart then, here is it: Press your phone’s power button. On the screen, tap Restart.

The other way of the reboot is as follows:

  • Press and hold the Volume Down button.

  • Tap the 3-dot at the top.
  • Select Auto restart.
