“A friend says they called me on LINE, but I never noticed...” “I only see missed calls, and the ringtone never plays.” Has this happened to you?

LINE call alerts not ringing or not showing up is still a very common issue on both iPhone and Android as of March 2026. The cause can be anything from LINE’s own notification settings to your phone’s battery-saving features, so it’s easy to get stuck wondering what to check first.

In this guide, we’ll walk through six common reasons LINE calls don’t ring, plus specific fixes for iPhone and Android. Try them from the top, and in most cases, you’ll be able to get your call notifications working again.

Cause 1: Notifications Are Turned Off in the LINE App

The first place to check is LINE’s in-app notification settings. This is surprisingly common: at some point, notifications may have been turned off without you realizing it.

How to check:

Open the LINE app, then tap “Home” → the gear icon in the top right (Settings) → “Notifications.” Check the following items there.

  • Make sure the main Notifications switch is on
  • Make sure Call notifications are on
  • Make sure notification sounds aren’t turned off

Also, if you’ve muted notifications for a specific friend or group, calls from that person or group may not ring either. Open the chat, tap the menu icon (≡) in the top right, and check whether notifications are turned off.

LINE’s official guide also recommends checking the app’s notification settings as the first step when troubleshooting notification problems.

Cause 2: Your Phone Is Blocking LINE Notifications

Even if notifications are turned on inside LINE, your phone’s system settings may still be blocking LINE alerts. The steps are different on iPhone and Android, so let’s go through each one.

On iPhone

Open “Settings” → “Notifications” → “LINE,” then check the following.

  • Make sure Allow Notifications is on
  • Make sure Sounds is on
  • Make sure at least one alert location is selected: “Lock Screen,” “Notification Center,” or “Banners”

If “Sounds” is off, you might still see a banner, but you won’t hear anything, making it easy to miss incoming calls.

On Android

Open “Settings” → “Apps” → “LINE” → “Notifications.”

  • Make sure Show notifications is on
  • Make sure notifications for the Calls category are on (Android 8 and later manage notifications by category)
  • Make sure the notification importance isn’t set to “Silent,” and is set to “Default” or higher

Android menus vary slightly by device and manufacturer. If you can’t find the setting, try typing “LINE” into the search bar in your Settings app.

Cause 3: Focus Mode, Do Not Disturb, or Silent Mode Is On

This one is easy to overlook. If Focus mode, Do Not Disturb, or Silent mode is on, notification sounds from all apps, including LINE, may be muted.

iPhone Focus Mode

Open Control Center by swiping down from the top right, then check whether “Focus” is turned on. If modes like “Do Not Disturb,” “Work,” or “Sleep” are active, notifications may not come through normally.

If you want to keep using Focus mode while still allowing LINE calls to ring, go to “Settings” → “Focus” → the mode you’re using → “Apps,” then add LINE to the allowed notifications list.

Android Silent Mode / Do Not Disturb

Go to “Settings” → “Notifications” → “Do Not Disturb” and check whether it’s turned on. If it is, turn it off temporarily and test whether LINE calls ring again.

Silent Switch / Manner Mode

On iPhone, check the silent switch on the left side of the device. If you see orange, Silent mode is on. On Android, press the volume button and make sure your notification volume isn’t set to zero.

“Ringtone volume” and “media volume” are controlled separately, so it’s possible to hear videos just fine while LINE calls stay silent.

Cause 4: Battery Saver Is Blocking Background Notifications

Your phone’s battery-saving features can limit background app activity. As a result, LINE may not be able to receive incoming calls in the background.

On iPhone

Go to “Settings” → “Battery” and turn Low Power Mode off. When Low Power Mode is on, the battery icon turns yellow, so it’s easy to spot.

Also go to “Settings” → “General” → “Background App Refresh” and make sure LINE is turned on.

On Android

Android battery optimization can be especially strict, and it’s one of the most common reasons LINE calls stop ringing.

  • Go to “Settings” → “Battery” → “Battery Saver” and turn it off
  • Go to “Settings” → “Apps” → “LINE” → “Battery” and choose Unrestricted
  • Go to “Settings” → “Apps” → “LINE” → “Mobile data” and turn Background data on

The LINE Help Center also recommends excluding LINE from battery optimization on Android devices. If you use a Galaxy, Xperia, OPPO, or another phone with manufacturer-specific power-saving settings, check those too.

Cause 5: “Integrate with iPhone Calls” Isn’t Set Properly (iPhone Only)

On iPhone, LINE has a setting called “Integrate with iPhone Calls,” which lets LINE calls appear on the same incoming call screen as regular phone calls. Depending on this setting, incoming calls may appear differently.

How to check:

LINE app → “Home” → Settings (gear icon) → “Calls” → “Integrate with iPhone Calls”

  • When on: LINE calls appear on the full-screen incoming call screen, just like regular phone calls
  • When off: Only a notification banner appears, which can be easier to miss when the phone is locked or asleep

If you’re having trouble noticing incoming calls, try turning this setting off and then back on. LINE’s official troubleshooting page also suggests this step.

Cause 6: LINE or Your Phone’s OS Is Outdated or Buggy

If you’ve checked all the settings above and LINE calls still don’t ring, the issue may be caused by an app or OS bug.

What to try, in order

  1. Update LINE to the latest version from the App Store or Google Play
  2. Update your phone’s OS to the latest version via “Settings” → “General” → “Software Update”
  3. Restart your phone. This fixes more issues than you might expect
  4. Clear LINE’s cache: LINE app → “Settings” → “Chats” → “Delete data” → delete “Cached data”
  5. If nothing else works, delete and reinstall the LINE app

Important: Before deleting LINE, make sure you back up your chat history. You can do this from “Settings” → “Chat backup.” Backups are saved to Google Drive on Android or iCloud on iPhone. If you delete LINE without a backup, your chat history may be permanently lost.

Checklist If LINE Calls Still Won’t Ring

If you’ve tried the six fixes above and the problem still isn’t resolved, check these items too.

  • Connection quality: Are you somewhere with weak Wi-Fi or mobile data? Is Airplane Mode turned on?
  • LINE account status: Are you logged in on another device? If LINE is being used on multiple devices, notifications may not arrive on one of them
  • Whether the other person is using “Mute messages”: This feature is mainly for regular messages, but it’s worth checking just in case
  • LINE server outage: Check Downdetector or search X (Twitter) for “LINE outage” or “LINE not working” to see whether there’s a wider issue

FAQ

Why do I only see missed calls even though LINE never rang?

If battery saver or Focus mode is active, LINE may not be able to receive the call notification in the background. After the call ends, you may only see a missed call. Start by checking battery optimization settings and Focus or Do Not Disturb mode.

Why do LINE messages notify me, but LINE calls don’t ring?

Inside LINE’s notification settings, message notifications and call notifications are managed separately. Go to LINE “Settings” → “Notifications” and check whether the “Calls” option is turned off. On Android, notification categories are also separated, so check your phone’s “Settings” → “Apps” → “LINE” → “Notifications” and review the “Calls” category there too.

What should I do if the LINE call rings for the other person but not for me?

That usually means the issue is on your phone. Work through Causes 1 through 6 in this article from the top. The two most common causes are “LINE is blocked in your phone’s notification settings” and “battery saver is stopping background activity.”

Will reinstalling LINE delete my chat history?

Yes, if you haven’t backed it up, your chat history can be deleted. Before reinstalling LINE, go to “Settings” → “Chat backup” and back up your chats to Google Drive on Android or iCloud on iPhone. Photos and videos may need to be saved separately.
