Fix Incoming Calls Not Showing on Samsung Galaxy

If incoming calls on your Samsung Galaxy phone ring or vibrate but the screen stays black or the call screen never appears, the fix is usually a combination of clearing the Phone app’s cache, checking notification and call settings, and making sure the screen isn’t being blocked by a faulty proximity sensor or a screen protector. Below are the exact steps to diagnose and resolve the issue on current Galaxy models running One UI.

Why Does the Call Screen Fail to Appear?

Your Galaxy phone uses two separate systems to handle an incoming call: the telephony radio (which receives the signal) and the Phone app (which draws the full-screen caller interface on top of whatever you are doing). When the call comes in but the screen doesn’t show it, one of these links is broken. Common culprits include:

• App cache corruption – the Phone app’s temporary files get stale and stop the UI from rendering.
• Notification settings – “Call notifications” may be set to “Brief” or “None,” which suppresses the full-screen caller ID.
• Proximity sensor misfire – if the sensor near the earpiece thinks the phone is against your ear, the screen stays off to prevent accidental touches.
• Screen protector or case – a thick or poorly aligned protector can block the sensor or the top speaker area.
• Do Not Disturb or Focus modes – these can silence calls and hide the incoming call banner.
• Third-party call blocker apps – apps like Truecaller or Samsung’s own Call Blocker can intercept the call before the UI shows.

Step-by-Step Fix: Clear the Phone App Cache

This is the single most effective fix and should be tried first. It does not delete your contacts or call history, only temporary files.

1. Open Settings → Apps.
2. Tap Phone (or “Phone” app, sometimes listed as “Call” on older One UI versions).
3. Tap Storage → Clear cache.
4. Do not tap “Clear data” unless you are prepared to reset call settings and possibly lose call history.
5. Restart the phone and test with a second device.

If the problem persists, also clear the cache of the Call Services app (if present) and the Samsung Call UI app (in some versions it’s called “Call Background”).

Check Notification and Call Settings

Galaxy phones let you choose how incoming calls are displayed. If you previously set notifications to “Brief” or “Silent,” the full-screen caller ID may be replaced by a small banner or nothing at all.

1. Go to Settings → Notifications → App notifications.
2. Find Phone and make sure Allow notifications is toggled on.
3. Tap Call notifications and select Full screen (or “Detailed” depending on your One UI version).
4. Also check Settings → Apps → Phone → Notifications and ensure “Incoming calls” is enabled with a sound or vibration.

Additionally, go to Settings → Advanced features → Motions and gestures and turn off “Turn over to mute” and “Palm swipe to call” if they are interfering – though these are less common causes.

Proximity Sensor and Screen Protector Issues

The proximity sensor sits just above the earpiece, usually hidden under the glass. If it falsely detects an object (like a dirty screen or a thick protector), the phone keeps the screen off during a call. To test:

1. During an incoming call, press the Power button once – if the screen turns on, the sensor is the problem.
2. Clean the top area of the screen with a microfiber cloth.
3. If you use a screen protector, remove it temporarily and test again. Some tempered glass protectors have a cutout for the earpiece but still block the sensor if misaligned.
4. In Settings → Display, check if “Accidental touch protection” is on – it can sometimes keep the screen dark in a pocket but should not affect an active call.

If the sensor is physically damaged (e.g., after a drop), you may need service. But first, try the software steps – they resolve the majority of cases.

Do Not Disturb, Focus Modes, and Call Blocking

Do Not Disturb (DND) can be scheduled or turned on manually, and it hides incoming call notifications by default. To check:

1. Open Settings → Notifications → Do Not Disturb.
2. Make sure it is Off or that “Calls” are allowed (tap “Allow exceptions” and enable calls from everyone or your favorites).
3. Also check Settings → Modes and Routines (or “Focus modes” on older versions) – a routine might be activating DND at certain times.
4. Open the Phone app → tap the three dots → Settings → Block numbers and review the block list. If a number is blocked, the call will not show at all – it will go straight to voicemail or be rejected silently.

Third-party call-blocking apps (like Truecaller, Should I Answer, or even Samsung’s own “Caller ID and spam protection”) can also suppress the screen. Temporarily disable them to test.

Software Update and Safe Mode

If the above steps fail, the issue may be a bug in the system UI. Two more things to try:

• Update your phone: Go to Settings → Software update → Download and install. Samsung regularly patches call-related bugs.
• Safe Mode: Restart the phone and hold the Volume Down button when the Samsung logo appears. In Safe Mode, third-party apps are disabled. If incoming calls show correctly in Safe Mode, a downloaded app is the culprit. Uninstall recently installed apps (especially call managers, battery optimizers, or launchers) and restart normally.

If the problem only occurs with a specific contact, check that contact’s ringtone – a corrupted ringtone file can cause the call UI to crash. Change the ringtone to a system default and test.

Frequently Asked Questions

Why does my Samsung screen stay black when someone calls?

The most common reason is a dirty or blocked proximity sensor. Clean the top area of the screen, remove any screen protector, and test. If the screen only stays black during calls, the sensor is likely the issue. If it stays black even when you press the power button, the Phone app may be crashing – clear its cache first.

Will clearing the Phone app cache delete my contacts?

No. Clearing the cache only removes temporary files like thumbnails and recently used data. Your contacts are stored in the Contacts app and your Google/Samsung account, not in the Phone app’s cache. You can safely clear it.

How do I make incoming calls show as a full screen instead of a banner?

Go to Settings → Notifications → App notifications → Phone → Call notifications and select Full screen. If you don’t see that option, update the Phone app via the Galaxy Store or Play Store, as older versions may not have it.

Why do calls go straight to voicemail without ringing?

This is usually caused by Do Not Disturb, a blocked number, or the “Call forwarding” feature. Check DND settings, the block list in the Phone app, and Settings → Connections → Call forwarding to ensure calls aren’t being forwarded. Also check if the number is on your spam list.

Can a third-party app cause the call screen to not appear?

Yes. Apps that overlay the screen (like screen dimmers, battery savers, or call recorders) can interfere with the incoming call UI. Boot into Safe Mode to test – if calls work there, uninstall apps that have “Display over other apps” permission, especially call-related ones.

What if none of these fixes work?

If you’ve cleared caches, checked notifications, tested in Safe Mode, and updated the software, the issue may be hardware – a damaged proximity sensor, a faulty earpiece, or a loose display connection. Contact Samsung support or visit a service center. Before that, back up your data and consider a factory reset as a last resort, but only after trying the simpler steps.
