The best Android phones can do just about anything these days — did you know they can even make phone calls, but you probably want to learn how to block incoming calls, right? You've probably gotten your fair share of spam calls in the last few years, and many carriers are actively working to prevent spam and "robocalls" from happening, but some people don't want to receive calls at all. Whether you use VoIP services, carry a work phone that only needs access to data, or prefer texting over calling, here's how you can quickly disable all incoming calls from ringing your phone.

Get familiar with Do Not Disturb mode

Do Not Disturb has been available since the release of Android Marshmallow way back in 2015. This feature makes it so you can either temporarily (or permanently) disable notifications from coming through. With Do Not Disturb enabled, you can set various rules and schedules for your phone to follow, muting notifications for certain contacts, time periods, and more.

The settings for DND have been fleshed out to the point that you can even make exceptions for different apps and different scenarios. It's the best way to get some peace and quiet whenever you need it while still allowing some more important notifications to make it through to you.

How to block incoming calls with Do Not Disturb

Disabling all incoming calls is easier than you might think. There's no need to fuss with questionable third-party apps or sit on hold with your carrier to ask for manual call barring. In most cases, it's as simple as tapping through a few menu screens.

1. Open the Settings app on your phone.

2. Scroll down and tap Sound & vibration

3. Tap Do Not Disturb

4. Under the What can interrupt Do Not Disturb section, tap People

5. Tap Calls

6. Tap None

7. Next to Allow repeat callers, tap the toggle to the Off position.

Now that the Do Not Disturb settings have been set to block any phone calls, you'll need to turn DND mode on. You can do this one of two ways. If you are still in the Do Not Disturb settings screen, tap the Turn on now button at the bottom of the screen. You can also simply swipe down to reveal the notification shade, swipe further to reveal the Quick Settings panel, and then tap Do Not Disturb.

What happened to the old "Call Barring" method?

The previous method involved a "Call Barring" feature and may still appear on some phones. This is related to the Sim Tools app, which is on just about every Android phone but is usually hidden from use. Whether it appears on your device or not is entirely up to your carrier. For those who want to try for the Call Barring method, here are the necessary steps:

1. Open the Phone app.

2. Tap the menu overflow button (three dots) in the upper right corner.

3. Tap Settings.

4. Tap Calls.

1. Within Call Settings, tap Call Barring.

2. Tap All Incoming (which should initially say "Disabled").

3. Enter the call barring password. In most cases, this will be either 0000 or 1234.

4. Tap Turn On.

Use an app to block those calls

If you don't have a Pixel or Samsung smartphone, you aren't completely left to deal with these repetitive calls. Thanks to the wonders of Android and the Play Store, you can grab one of the best Android apps, which can help to serve the same purpose. One of these apps has even partnered with Samsung to provide spam call prevention on a system level. So here are a couple of apps for you to check out if you want to block calls.

Hiya: Spam Blocker & Caller ID

Hiya: Spam Blocker & Caller ID

Hiya has partnered with Samsung to provide spam protection for various devices. But the standalone apps work with many of the best Android phones, so you can block spam calls, look up phone numbers, and take advantage of its Caller ID functionality. This put a name to the number, giving you a better idea of whether you should answer the call or block the number.

Robokiller - Robocall Blocker

Robokiller - Robocall Blocker

RoboKiller is another great application that claims to block up to 99% of spam calls that come to your phone. There's a seven-day free trial, and then you'll have to sign up for a subscription if you decide that RoboKiller is worth blocking those calls.

Truecaller: Caller ID &amp; Block

Truecaller: Caller ID & Block

Unlike Robokiller, you don't have to worry about a free trial if you want to use Truecaller. The app is free to download and use, but if you want to unlock additional functionality, there are in-app purchases available. Recent updates to the app have introduced Truecaller Assistant which works similarly to Google's Call Screening.

Blocking specific numbers on your Samsung phone

1. Open the Phone app.

2. Tap Recents at the bottom of the app.

3. Locate the number you wish to block and tap on it.

1. Open the Phone app.

2. Tap the three-dot overflow menu icon in the top right-hand corner.

1. Open the Phone app.

2. Tap the three vertical dots in the top right corner.

3. From the drop-down menu, tap Settings

4. Under the Assistive section, tap Spam and Call Screen

There are plenty of ways to block calls

There seems to be a neverending influx of phone calls warning you about your "car's expiring warranty," or some other bogus claim. Thankfully, we don't need to try and find the best apps from the Play Store in hopes of trying to block them. Instead, you can just rely on the different settings and options built into Android!
