We will give you several options to block unwanted calls on an Android mobile, so you can find the combination of peace of mind and continue receiving the calls that matter to you, both from your contacts and unknown numbers.

Turn on Google's spam filter

Google has long improved the spam call filter included in its phone app. Today, Google's phone app is the default app for a good number of mobiles, becoming somewhat the standard.

The good news is that if your phone comes with its own phone dialer app, you can usually download Google Phone from Google Play and take advantage of its caller ID and spam features. However you purchased the app, you'll need to make sure that the call filter is active. To do this, go to the Caller ID and spam section of the settings.


Here you will find three closely related options. The first one helps you distinguish calls that are spam from those that are not, trying to identify who is on the screen that appears when they call you. For example, you will see that the call is from "Pelaez Hairdresser". The second is the most important of all, Filter spam calls. If you activate it, the app automatically declines calls that it considers to be spam, and alerts you with a notification.

The third option, Verified calls, allows businesses to identify themselves and add a reason for the call, which you'll also see before you pick up. To turn on spam blocking for the Google app, follow these steps:

  • Open the Google Phone app.

  • Tap the ⋮ menu and choose Settings.

  • Go to Caller ID and spam.

  • Turn on Filter spam calls.

  • If you want, you can also turn on View Caller ID and Verified Calling, which will give you more information about who's calling before you pick up.

Block them as they arrive

Google's spam filter is pretty good, but not foolproof. Sooner or later you will get calls that are obviously spam and various scams. Many of these cases will be marked as "possible spam" in the phone app, but in other cases they could appear as normal calls.

The good news is that you can help rid the world of spam by informing Google of it. In your call history, tap the call in question and tap Mark as spam. This informs Google and also blocks the number.


After you mark a number as spam in the Google app, the next calling attempts you receive will go straight to the trash. Normally, spammers use several numbers, but by blocking numbers incessantly in the end you will achieve some peace. Here are the steps to block a number that has called you:

  • In the phone app, tap Recent.

  • Tap on the call.

  • Tap Mark as spam.

  • Click Mark as spam again.

Goodbye, hidden numbers

If it is

the hidden numbers that do not stop bothering you, there is also a solution for it, although keep in mind that this filter does not discriminate so that you could miss calls with hidden number that are important.


To block all hidden numbers on an Android phone, go to the phone app's settings and tap Blocked numbers. There, select the Unknown check box. Here are all the steps:

  • Open the Google Phone app.

  • Tap the ⋮ menu and choose Settings.

  • Tap on Blocked numbers

  • Turn on Strangers

What if my phone has another phone app?

Not all Android phones come with Google's phone app pre-installed, but they come with their own app. In this case, you depend on the mobile layer having its own call filter, something that does not always happen. Yes, there is usually a way to block calls (sometimes, even entire prefixes), or allow calls only from a closed list of phones, as in Huawei's EMUI.

EMUI call filter options

In most cases, you'll be able to install the Google Phone app to take advantage of Google's spam filter, but if you receive a huge number of spam calls and they escape Google's filter, you may need something stronger.

In this case, an application like Truecaller can be useful, which is something like the standard of identification and blocking of calls. The app is not without controversy, especially in the way it accumulates user data, and of course it is not very light, so you should assess what you get and what you should offer in return.

If the Google filter or the one that comes with your mobile falls short, you will always have Truecaller

Truecaller has years of experience identifying calls and a huge user base, so it is quite likely that any spam call attempt will be correctly identified. If Truecaller does not convince you, there are other similar apps to block call
