LINE is a popular instant messaging service that allows users to send messages, make phone calls, and share media files. Its appealing features and user-friendly interface have helped it expand its user base globally.

However, some users may experience issues with the app, such as LINE app crash or getting stuck on loading screens. These problems can be frustrating, especially if you need to communicate with others urgently.

In this article, we will discuss the possible reasons why the LINE app crashes and offer solutions to fix the issue.

Part 1: The Possible Reasons Why LINE App Crash

There could be several reasons that could lead to a LINE app crash, including network issues, app bugs, insufficient storage, outdated app versions, and software incompatibility.

Sometimes, the app may also freeze and stop responding to user commands, leading to a stuck loading screen. These issues can prevent users from accessing their chats, making calls, and sending messages.

Part 2: Top 10 Fixes for LINE App Crash or Stuck on Loading Issue

Here are the top 10 solutions to fix LINE app crashes or stuck loading screens:

Solution 1: Check the Server Status

Sometimes, a LINE app crash occurs due to server issues. To check the server status, you can visit the LINE official website or social media pages. If there are any server issues, you must wait until the situation is repaired. As an alternative, you can try connecting to several servers using a VPN to determine whether the issue still continues.

Solution 2: One-Click Fix LINE App Crash or Stuck on Loading Issue on iPhone & Android

If you've tried restarting the LINE app and your device, and you're still experiencing issues with the app crashing or getting stuck on the loading screen, you may want to try using a third-party system recovery tool like Tenorshare ReiBoot or Tenorshare ReiBoot for Android. These tools are specifically designed to repair iOS and Android system issues, including issues with LINE app crashes or stuck loading screens.

Here are the steps to use Tenorshare ReiBoot's Standard Repair mode to fix LINE app crash or LINE app stuck on loading.
