Fix No Signal issue on Galaxy A50

Verify signal strength

In a lot of network issues, poor or weak signal is to blame. If your Galaxy A50 is showing No Service all the time recently, be sure to check how the signal bars are showing on your device. Anything lower than 3 bars is not good and can indicate a network issue.

If you are inside a building, try to go out and see if No Service goes away. If you are traveling by car, it’s possible that you may be transiting a dead spot. What you want to do is to move to a known well-covered area. If No service remains, there may be an issue with your Galaxy A50. Continue troubleshooting it by following the steps below.

Check if voice calling works

Some carriers may have 4G LTE issues which can also affect other network services. Try checking if texting or voice calling is intermittent or having random issues. If they do have a problem even if there are excellent signal bars, there may be an issue with your network. You must contact your network operator for help.

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.
  • While holding it down, press and hold the Power key.
  • Keep the button held for 10 seconds, it will be restarted automatically.

If this doesn’t work then head to the next method.

Contact Your Carrier

No Service bug can be caused by an issue from your network operator so you won’t be able to fix it on your end at all. Talk to your carrier and let them check the problem if nothing is fixed after a factory reset.

Visit the Service Centre

Although it’s rare, some cases of the issues on Samsung Galaxy devices may have bad hardware as the origin. If a factory reset won’t help in fixing your issue, visit your local Samsung store or Service Center so a qualified Samsung technician can examine the hardware. If needed, they may send it in for repair or replacement.
