How to stop pop-up notifications on Android?

Pop-ups on Android come from three different places, and the right fix depends on the source:

Your web browser: Chrome site pop-ups and website notification prompts.
Individual apps: heads-up or pop-on-screen notifications.
Ad or spam pop-ups: caused by a misbehaving or malicious app.

To stop the most common ones, browser pop-ups in Chrome:

Open Chrome and tap the three-dot menu (top right).
Go to Settings > Site settings > Pop-ups and redirects and toggle it off.
Go back to Site settings > Notifications and turn the top Notifications toggle off so websites can no longer prompt or push to you.

The full steps for every other kind of pop-up, including app notifications, Samsung devices, ad/malware pop-ups, and Do Not Disturb, are below.

Why you're getting pop-ups on Android

Before you start flipping switches, it helps to know which kind of pop-up you're dealing with, because each one is controlled in a different place. Browser pop-ups and redirects are the new windows or tabs that open while you browse. Website notification pop-ups are the alerts you receive after a site asks for permission to send notifications in Chrome. App heads-up notifications are the banners that slide down from the top of your screen when an installed app has something to tell you. And ad or spam pop-ups, especially full-screen ones that appear when you aren't even browsing, usually point to a bad app injecting ads. Once you know the source, jump straight to the matching section.

Stop website pop-ups and redirects in Chrome on Android

These are the new-window and redirect pop-ups that hijack your browsing. Chrome blocks most of them by default, but the setting can be turned off, so confirm it's active.

Open Chrome and tap the three-dot menu in the top-right corner.
Tap Settings, then scroll to Site settings.
Tap Pop-ups and redirects.
Toggle it off so the slider shows that pop-ups and redirects are blocked.

This blocks pop-ups while you browse. If a trusted site (say, a banking portal that opens a secure window) genuinely needs pop-ups, you can add it to the Allowed list from the same screen instead of switching the feature back on globally.

Stop website notification pop-ups (push notifications) in Chrome

If banners from random websites keep appearing, you (or a tap you didn't mean) granted those sites notification permission. The cleanest fix is to stop the requests at the source rather than dismissing alerts one by one.

In Chrome, tap the three-dot menu, then Settings > Site settings > Notifications.
Turn the top Notifications toggle off to block sites from both asking and sending.
If you'd rather keep notifications available but stop the interruptions, leave the toggle on and choose the quieter behavior so sites can ask without a pop-up appearing.
To silence just one site, visit it, tap the page-info icon in the address bar > Permissions > Notifications and switch Show notifications off. You can also find the site under Allowed in Site settings > Notifications and move it to Blocked.

Turn off pop-up (heads-up) notifications for individual apps

If a specific app keeps sliding banners down from the top of the screen, you can mute just that behavior at the operating-system level. These steps follow stock Android 14/15 (Pixel); labels may differ slightly on other phones.

Open Settings > Notifications > App notifications (called Apps & notifications on some versions).
Tap the app whose pop-ups you want to stop.
Open a notification category (channel), then turn off Pop on screen so its alerts stay quietly in the shade.
To silence the app completely, toggle off its notifications at the top of the same screen.

There's no single switch to kill every heads-up pop-up at once; control is per app and per channel. On Android 15, you can also enable Notification cooldown (Settings > Notifications > Notification cooldown) to automatically lower the volume of rapid back-to-back alerts, which cuts down on noisy bursts from chatty apps.

Stop pop-up notifications on Samsung Galaxy (One UI)

Samsung's One UI labels things a little differently, and it adds a handy option to shrink how much of the screen a notification takes up. These steps apply to One UI 6/7.

Go to Settings > Notifications > App notifications and toggle off any app you want to block entirely.
To fine-tune, tap an app and open its Notification categories to disable only specific alert types.
To change the style so alerts don't dominate the screen, go to Settings > Notifications > Notification pop-up style and choose Brief instead of Detailed.
For a quick one-off fix, pull down the notification shade, long-press a notification, tap the gear/Settings icon, and turn it off or mute it.

Stop ad and spam pop-ups (and check for malware)

Aggressive, full-screen ad pop-ups that appear at random, even on your home screen, almost always come from a rogue app rather than a setting. Here's how to track it down and clear it out.

Boot into Safe Mode: press and hold the power button, then long-press Restart until you see the prompt to reboot into safe mode. If the pop-ups stop, a downloaded app is the cause.
Uninstall recently added or suspicious apps one at a time, restarting normally after each to see which one was responsible.
Turn on Google Play Protect: open the Play Store > profile icon > Play Protect, then run a scan and keep app scanning enabled.
In Chrome, block any site that's pushing spam from Site settings > Notifications so it can't slip alerts back in.

To avoid a repeat, install apps only from the Play Store and steer clear of sideloaded APKs from unknown sources, which are the most common way ad-injecting code reaches a phone.

Use Do Not Disturb to silence all pop-ups temporarily

When you just need quiet for a while, Do Not Disturb hides heads-up pop-ups, mutes sounds, and can suppress lock-screen alerts, all without permanently changing your per-app settings.

Swipe down the Quick Settings panel and tap Do Not Disturb, or open Settings > Notifications > Do Not Disturb.
Set exceptions for things you don't want to miss, such as alarms or starred contacts.
Optionally add a schedule so DND turns on automatically (for example, overnight) and off again in the morning.

Stop notification pop-ups on the lock screen

If your worry is alerts popping up where anyone can read them, you can hide them on the lock screen without turning the notifications off entirely.

On stock Android, go to Settings > Notifications > Notifications on lock screen. On Samsung, go to Settings > Notifications > Lock screen notifications.
Choose Don't show notifications to stop them appearing, or Hide content to show that something arrived without revealing the details.

A note for app and web developers

If you build apps or websites rather than just use them, the flip side of this guide matters too: you need to verify how your own notifications, permission prompts, and web-push behavior render across real Android devices, OS versions, and browsers, because heads-up notifications and prompts behave differently on Android 13, 14, and 15 and across One UI builds. TestMu AI's Real Device Cloud lets you test notification and pop-up rendering and permission flows on hundreds of real Android devices and Chrome versions, so you can confirm the experience matches what your end users actually see.

Frequently Asked Questions

Why do I keep getting pop-up notifications on my Android?

Most repeat pop-ups come from one of three sources: website push notifications you allowed in Chrome, heads-up notifications from installed apps, or an ad-injecting or malicious app. Identify which source is firing, then apply the matching fix, block site notifications in Chrome, turn off pop-on-screen for the app, or remove the bad app.

How do I turn off all pop-up notifications at once on Android?

Android has no single master switch for heads-up pop-ups. For a quick blanket silence, turn on Do Not Disturb from Quick Settings. For a permanent fix, disable pop-on-screen per app or per notification channel under Settings > Notifications.

How do I stop pop-up ads in Chrome on Android?

Open Chrome, tap the three-dot menu, then go to Settings > Site settings > Pop-ups and redirects and switch it off. Also open Site settings > Notifications and turn the top toggle off so websites can no longer prompt or push to you.

Why am I getting random full-screen pop-up ads even when I'm not browsing?

A recently installed app is the most likely cause. Boot into Safe Mode to confirm the pop-ups stop, uninstall the suspicious app, and run a scan with Google Play Protect to be sure nothing else is injecting ads.

How do I stop pop-up notifications on a Samsung phone?

On One UI, go to Settings > Notifications > App notifications and toggle off the app you want to silence, or set Notification pop-up style to Brief so alerts no longer take over the screen.

How do I stop notifications from showing on my lock screen?

Open Settings > Notifications > Notifications on lock screen (Settings > Notifications > Lock screen notifications on Samsung) and choose to hide content or to not show notifications at all so previews stop popping up on the lock screen.
