Android Phone Not Receiving Calls | Stop Missed Calls

Missing calls is maddening. You’re holding the phone, the signal looks fine, and yet people say it goes straight to voicemail. Then you notice a missed call notification minutes later and wonder what just happened.

Most of the time, it’s not a dead antenna or a ruined phone. It’s a setting, an app permission, or a network state that got stuck. The steps below start with the fastest checks, then move into the less obvious settings that silently block incoming calls.

Android Phone Not Receiving Calls With Fast Checks

Run these in order. Each one removes a common “no ring” cause without digging through deep menus.

• Turn Off Airplane Mode — Open Quick Settings, switch Airplane mode off, and wait for the signal bars to refresh.
• Turn Off Do Not Disturb — Disable Do Not Disturb, then check that calls are allowed if you use schedules.
• Raise Ring Volume — Press a volume button, open the full volume panel, and raise Ring volume (not media volume).
• Switch To Loud Ringtone — Pick a ringtone you can hear across a room, then test with a call from another phone.
• Check Bluetooth Audio — Turn Bluetooth off and retry a call in case audio is routing to earbuds or a car system.
• Restart The Phone — Power the phone fully off, wait 15 seconds, then power on to refresh cellular registration.
• Test With Another Caller — Call from a different network if possible to rule out a one-carrier routing hiccup.

If your phone rings during the test, you can stop here. If it still stays silent, move on. The next sections narrow down whether the issue is alerts, network registration, or call handling settings.

Fix Android Not Receiving Calls After An Update

After a system update, call alerts can break in a boring way: a permission flips, the Phone app loses a setting, or battery rules clamp down on the full-screen incoming call alert. You may still receive the call in the background, then see it later as missed.

Confirm Phone App Permissions

Incoming call screens depend on a few permissions working together. If one is denied, the call can land without a proper alert.

1. Open App Permissions — Settings > Apps > Phone (or Dialer) > Permissions.
2. Allow Phone And Contacts — Enable the permissions for Phone and Contacts so caller info and call UI can load.
3. Allow Notifications — In the Phone app’s notification settings, make sure call alerts are enabled.

Fix Incoming Call Notifications

Some Android builds treat the call screen like a special notification. If that channel is muted, you get silence.

• Enable Incoming Call Alerts — Settings > Apps > Phone > Notifications, then turn on the call alert category.
• Allow Lock Screen Alerts — Set calls to show on the lock screen so you see them while the phone is asleep.
• Enable Full Screen Intent — Turn on full-screen call alerts if your device offers that toggle.

Loosen Battery Rules For The Phone App

Battery restrictions can delay the pieces that pop the call screen. This varies by brand, so the labels may differ.

1. Turn Off Battery Saver — Disable Battery saver and retry a test call.
2. Set Phone To Unrestricted — Battery settings > App battery usage, then set Phone to unrestricted behavior.
3. Allow Background Activity — If you see a background toggle for Phone, turn it on.

Update The Right Components

Call alerts rely on the Phone app plus a few system pieces that ship updates through the Play Store.

• Update Phone App — Open Play Store, search for Phone, and update it if an update is available.
• Update Carrier Services — Update Carrier Services so network configuration stays current.
• Restart After Updates — Restart once after updating to reload services cleanly.

Network And SIM Checks That Affect Incoming Calls

Calls require the phone to stay registered for voice service. You can have usable data and still miss calls if voice registration is unstable, the SIM is loose, or the network mode keeps switching.

Force A Fresh Network Attach

If your status bar keeps bouncing between network labels, your phone may be reattaching often. That can kill incoming calls.

1. Toggle Airplane Mode — Turn it on for 10 seconds, then off to trigger a fresh attach.
2. Restart The Phone — Restart again after the toggle if the signal still looks jumpy.
3. Move To A New Spot — Step outside or near a window and retry a call.

Reseat The SIM Card

A SIM that’s slightly off in the tray can cause random call failures. Reseating takes a minute and rules out a simple hardware fit problem.

• Power Off First — Shut down fully before pulling the SIM tray.
• Clean The SIM Surface — Wipe gently with a dry microfiber cloth, then reinsert.
• Seat The Tray Flat — Push the tray in until it’s flush with the frame.

Check Dual SIM And eSIM Settings

Dual-SIM phones can route voice through a line with weak coverage. If the wrong line is set for voice, callers may not reach you.

1. Set Default Voice Line — Settings > Network & internet > SIMs, then choose the SIM for calls.
2. Disable The Second Line — Turn the other SIM off for five minutes and run a call test.
3. Re-enable After Testing — Turn it back on once you confirm which line is stable.

Review VoLTE And Wi-Fi Calling

Many carriers route voice over LTE. If VoLTE is off, calls can fail in areas where older voice networks are limited.

• Turn On VoLTE — In mobile network settings, enable VoLTE or LTE calling if you see it.
• Toggle Wi-Fi Calling — Turn Wi-Fi Calling off, test, then turn it on again if you use it.
• Restart Router — If failures happen only on Wi-Fi, power-cycle the router for 30 seconds.

Call Settings That Send People To Voicemail

Android offers several places where calls can be blocked, silenced, screened, or forwarded. If callers report that it rings once or goes straight to voicemail, focus here.

Remove Blocked Numbers

Blocked numbers are the simplest cause. They can be added by mistake from a call log swipe or spam action.

1. Open Blocked Numbers — Phone app > menu > Settings > Blocked numbers.
2. Unblock Needed Contacts — Remove any number that should be able to reach you.
3. Retest Calls — Ask the same person to call again to confirm the change.

Tune Spam Filtering

Spam filtering can catch real calls, especially from offices, banks, delivery drivers, or new numbers. Keep protection on, yet reduce false blocks.

• Open Caller ID And Spam — In Phone settings, find the caller ID and spam section.
• Turn Off Call Blocking — If there’s a separate toggle for blocking suspected spam, turn it off and keep caller ID on.
• Check Recent Spam Log — If your Phone app shows filtered calls, mark legit numbers as not spam.

Turn Off Call Forwarding

Forwarding can send calls to voicemail or to another number without you noticing, especially after carrier changes or dialed codes.

1. Open Call Forwarding — Phone app > Settings > Call forwarding.
2. Disable All Forwarding Options — Turn off “Always,” “When busy,” “When unanswered,” and “When unreachable.”
3. Run A 30-Second Test — Have someone call and let it ring for at least 30 seconds to confirm it stays on your phone.

Check Do Not Disturb Exceptions

Do Not Disturb can allow some calls and block the rest. That’s great at night, rough during the day if the rules are too strict.

• Allow Calls From Anyone — In Do Not Disturb settings, set calls to allow all callers while testing.
• Allow Repeated Callers — Turn on repeated callers so a second call within minutes rings through.
• Review Schedules — Disable schedules during testing so you’re not chasing a hidden rule.

Resets That Clear Stuck Call Glitches

If settings look right and calls still fail, the Phone app or network stack may be stuck. These resets are targeted. They won’t erase photos, messages, or files.

Clear Phone App Cache And Storage

Cache clearing is low risk. Storage clearing resets the Phone app’s internal settings, so plan to re-check spam and block options afterward.

1. Open Storage Settings — Settings > Apps > Phone > Storage & cache.
2. Clear Cache — Tap Clear cache, then test an incoming call.
3. Clear Storage — Tap Clear storage, reopen the Phone app, then run another call test.

Reset Wi-Fi, Mobile, And Bluetooth

If your android phone not receiving calls problem has survived all checks so far, a network reset is the next clean step. It wipes saved Wi-Fi networks and Bluetooth pairings, so you’ll need to reconnect afterward.

• Open Reset Options — Settings > System > Reset options (menu names vary by brand).
• Reset Connections — Tap reset for Wi-Fi, mobile, and Bluetooth, then confirm.
• Restart And Retest — Restart the phone and test calls on cellular before turning Wi-Fi Calling back on.

Test In Safe Mode

Some apps can interfere with call alerts by grabbing notification priority, drawing over other apps, or acting as a dialer replacement. Safe mode lets you test without uninstalling everything first.

1. Enter Safe Mode — Hold the power menu, long-press Power off, then confirm Safe mode.
2. Place A Test Call — Call your phone from another number and watch for the full-screen alert.
3. Remove Recent Call Apps — If safe mode fixes it, uninstall recent dialer, call recording, or spam apps one at a time.

When The Carrier Or Hardware Is The Real Cause

Sometimes the phone is fine and the line isn’t. Other times the SIM tray or radio hardware is failing. The goal here is a clean yes-or-no answer in under an hour.

Check For Outages And Account Holds

If multiple people on the same carrier can’t reach you, or your line shows “no service” in places it used to work, the issue may be upstream.

• Test Another Phone — Try a second phone on the same carrier in the same location.
• Check Plan Status — Confirm your account is active and the line isn’t suspended.
• Change Locations — Move a short distance and run another call test to rule out a local tower issue.

Request A SIM Swap Or Line Refresh

If the SIM is old, worn, or cut down from a larger size, a fresh SIM can fix flaky voice registration. Carriers can also refresh the line settings from their side.

1. Ask For Line Refresh — Request a refresh of voice services and VoLTE for your line.
2. Swap The SIM — Get a new SIM and test calls on cellular with Wi-Fi off first.
3. Retest Over A Full Day — Run a few inbound tests across the day to confirm stability.

Rule Out Number Porting And Routing Problems

If you recently changed carriers, inbound calls can fail while outbound calls work. Routing can be wrong between networks until it’s corrected.

• Confirm Port Completion — Ask the carrier to confirm the port shows complete on their side.
• Test From Multiple Networks — Try calls from at least two different carriers to see if failures cluster.
• Request Routing Repair — Ask customer care to open a routing ticket if specific networks can’t reach you.

Use Two Simple Cross-Tests

If your android phone not receiving calls issue still happens after safe mode and a network reset, these two tests usually point to the culprit.

1. Test Your SIM In Another Phone — If your SIM can’t receive calls in a different phone, the SIM or line is the likely cause.
2. Test Another SIM In Your Phone — If a different SIM receives calls fine on your phone, the phone hardware is less likely to be at fault.

If the cross-tests point to the phone, a repair shop or the device maker can run radio diagnostics. If they point to the line, a carrier store can swap the SIM and verify voice registration on the spot.
