Private calls are made when the caller blocks their number from appearing on the Caller ID. These calls appear with “No Caller ID” or “Restricted” displayed on your phone. You may have noticed such private calls are automatically rejected on your phone or may be going straight to your voicemail. How can you fix this?
To accept private calls on your Android phone, toggle off the feature to block unknown/private numbers in your Phone app settings. You may also need to ask your carrier to unblock private calls on their end. Check no other third party app is blocking private calls, and make sure Do Not Disturb mode is disabled.

Why does my phone automatically reject private and restricted calls?
The following are some of the reasons why your Android phone may automatically reject private and restricted calls without ringing:
1. The default is set to block private and restricted calls
If you are using the built-in setting on your Android device for private and restricted call blocking, this may result in automatic rejection of these calls.
In your Phone app, you need to toggle off the option to receive private and restricted calls.
See section “How do I accept calls from private numbers” for how to this .
It’s also possible that an individual restricted call is blocked via the “Block number” option provided in the call log entry. You can unblock it via the option provided in the Phone app to receive and accept such calls:
- Launch Phone app > call log.
- Long press on the blocked entry.
- Tap on “Unblock Number” in the menu that shows up.
- Choose Unblock in the popup.
2. Your carrier is blocking private and restricted calls
Your carrier may be blocking private calls, resulting in these calls being rejected. Contact your carrier to find out if the blocking of private and restricted calls is on their side and ask them to remove that.
3. A third-party app is blocking the private and restricted calls
Another possibility is that a third-party app (e.g. Hiya) is blocking private and restricted calls. Go into the app’s settings and turn off any option that blocks incoming hidden numbers.
Alternatively, you can uninstall the app to start receiving private and restricted calls on your phone again.
4. You have Do Not Disturb enabled on your phone
You may have Do Not Disturb mode enabled on your Android device. This feature automatically rejects calls, including private and restricted calls, except those that are allowed through e.g. your favorite contacts.
Here’s how to disable this mode:
- Go to Settings > Sound & Vibration > Do Not Disturb.
- Toggle off “Do Not Disturb” at the top.
How do I accept calls from private numbers?
To be able to receive and accept calls from private numbers, do the following on your Android device:
- Open the Phone app > Settings
- Select “Blocked Numbers”.
- The Harassment Filter page will open up. Toggle off “Block Unknown/Hidden Numbers”.
Calls from private numbers will now be unblocked.
How do I unblock private numbers on Samsung?
Here’s how to unblock private numbers on your Samsung Galaxy device:
- Launch Phone app > tap on the three-dot menu.
- Navigate to Settings > Block Numbers.
- Toggle off “Block Unknown/Private Numbers”.
How can I identify an unknown number?
If you’ve received calls from unknown numbers or private ones (without any Caller ID), here are some things you can try to identify them:
1. Enter the unknown number in a search engine
You can enter the unknown number in Google. The results may indicate where the number is from and who called you, e.g a bank or a company you have business with.
2. Use a reverse phone lookup website
There are many reverse phone lookup websites that can help you identify unknown numbers.
These websites generally provide number information without any charge. Some examples of reverse phone search websites include:
3. Dial *69 or *57 immediately after the call
If you dial *69 on the keypad after a missed call from an unknown number, it will trace the person who called you. Details such as the name and address of the caller will appear if available in public databases.
This also works for private and anonymous calls, so you can trace the person who called you and reveal the phone number.
You can also dial *57 instantly after the call; this will result in a request to the carrier to trace the caller and find out the caller’s details. This is recommended in the cases you are being harassed by scam or spam calls.
When dialing *57, this will also generally send the information to the police. Thus, law enforcement authorities can find out who is threatening.
4. Use a call blocking app
You can use an app such as TrapCall to identify unknown and private incoming calls on your Android phone. The app can reveal the phone number and caller details for private, unknown, and anonymous calls.
It can also block spam calls automatically.
Can I call back a No Caller ID?
If you missed a call with no Caller ID, it’s still possible to call them back as follows:
- Use the Last Call Return Service: dial #69 on your mobile or *69 on landlines to call back the last caller Typically this can be done within 30 minutes of the last call you received, or the time limit set by your service provider.
- Go through the call log provided by your service provider and then match the date and time on the call log on your phone to identify the private number you wish to call back.
- Use a paid service such as the TrapCall app on your Android device: it will automatically reject any private call and then show the Caller ID and phone number that you can call back.
What is the best way to block private number calls on Android?
The easiest way to block private numbers on your Android device is to use the built-in Android feature. Here’s how on a Samsung Galaxy device:
- Open the Phone app > three-dot menu > Settings
- Go to “Block Numbers”
- Toggle on “Block Unknown/Private Numbers”
Using a third-party app
If your Android phone doesn’t have a built-in blocking feature or you need more effective private call blocking functionality, you can use a third-party call blocking app.
Such an app not only protects your phone from unwanted calls but also aids in recognizing unknown numbers.
The Google Play Store has an abundance of apps that block private calls; some of the best ones that are free with in-app purchases include:
Block Unknown Callers not working on Android?
Here are common reasons unknown caller blocking may not be working on your Android phone:
1. The Phone app is not working properly
There may be issues with the Phone app, which can affect unknown caller blocking.
To solve the problem, you can try to clear the cache of the Phone app as follows:
- Long-press on the Phone app’s icon and tap on the “i” icon in the menu.
- Scroll down and tap on Storage.
- Tap on “Clear Cache” at the bottom.
Another thing you can try is to reset app preferences as follows:
- Go to Settings > Apps > Three dot-menu
- Choose ”Reset App Preferences”.
- In the popup that appears, tap Reset to confirm.
Note that this will clear the default settings for all the apps and enable all disabled apps. However, you won’t lose any data.
If the above methods don’t work and you still receive unknown calls, you can try using a third-party app as described in earlier sections.
You can also try contacting your carrier as ask them to block unwanted calls at the network level.
2. Background battery usage for the Phone app is not allowed
If the background battery usage for the Phone app is not allowed on your device, this can also result in unknown caller blocking not working properly.
Background battery usage for an app refers to whether the app is allowed to run in the background when you are not using it. If allowed, the phone’s battery is being used to let the app run to its fullest extent without any restriction.
Thus, the Phone app can function fully if background battery usage is allowed, which includes the blocking of unknown callers.
Here’s how to allow background battery usage for the Phone app :
- Long-press on the Phone app icon.
- Tap on the “i” icon > Battery
- Check that “Allow Background Activity” is toggled on.
