How to solve common issues with Line app?

There are several most common issues with the messenger. Let‘s discover how to solve each one.

  1. Your application crashes.
  • Update your operating system. In most case, your app is crashing due to incompatibility with the operating system of your device.
  • Reinstall your program. For these purposes, delete the program completely and then download and install it one more time.
  • Clear your device memory (cache). Free more space for Line — it might be crashing due to lack of free space on your gadget. You can also turn on Background App Refresh that will eliminate overloading your cache by the messenger. Go to Settings — Line — Background App Refresh.


  • Check whether the app is down. For these purposes, visit https://downdetector.com/status/line and make sure the service is working properly. In case it‘s not, wait until the developers will fix the issue.
