How to Stop Pop-ups on Samsung Galaxy S10?

Pop-ups on a Samsung Galaxy S10 come from four places, and each has its own fix. To block web pop-ups, turn on the pop-up blocker in Samsung Internet (Menu > Settings > Sites and downloads / Privacy dashboard > Block pop-ups) and in Chrome (⋮ > Settings > Site settings > Pop-ups and redirects > off). To stop app pop-up notifications, head to Settings > Notifications and disable the pop-up style for the offending apps. If you keep getting full-screen ad pop-ups, a rogue app is almost always the cause, so find it with Safe Mode and uninstall it. The exact steps for each, plus the One UI Smart pop-up view, are below. Labels vary slightly by One UI version, so both common path names are shown.

Why You're Getting Pop-ups on Your Galaxy S10

Knowing which kind of pop-up you are fighting matters, because the fix is different for each. The Galaxy S10 launched on Android 9 Pie with One UI 1.1 and is supported up to One UI 4.1 on Android 12, so the exact menu labels shift a little between versions, but the four underlying sources stay the same.

• Browser web pop-ups: new windows, tabs, and redirects triggered by pages you open in Samsung Internet or Chrome. These are stopped with each browser's built-in pop-up blocker.
• Website push notifications: alerts from sites you once tapped "Allow" on. They keep arriving even when the browser is closed and are controlled under the browser's notification permissions.
• App heads-up notifications: banners and floating alerts from installed apps that are configured to pop on screen. These live in One UI's Settings > Notifications.
• Rogue ad-injecting apps: full-screen ads that appear over your home screen or other apps, usually from a recently installed free app abusing the "appear on top" permission. This is the most disruptive source and needs Safe Mode to track down.

Work through the sections that match your symptoms. If you are on a non-Samsung handset or want the broader stock-Android walkthrough, see How to Stop Popup Notifications on Android? for the generic baseline.

Block Web Pop-ups in Samsung Internet

Samsung Internet is the default browser on the S10 and has its own pop-up blocker that is independent of Chrome. The setting moved across One UI versions, so both common paths are listed below.

• Open Samsung Internet and tap the Menu icon (three horizontal lines) in the bottom-right corner.
• Tap Settings from the menu sheet that slides up.
• Open Sites and downloads on older builds, or Privacy dashboard (sometimes labelled "Browsing privacy dashboard") on newer One UI versions.
• Find Block pop-ups and toggle it on.
• Optionally, return to Settings and open the Ad blockers menu to install a content blocker, which removes most banner and interstitial ads from sites you visit.

Block Pop-ups and Redirects in Chrome

If you browse in Chrome on your S10, its blocker is a separate toggle that you have to set on its own. Turning it off in Samsung Internet does nothing for Chrome.

• Open Chrome and tap the three-dot menu (⋮) in the top-right corner.
• Tap Settings, then scroll down to Site settings.
• Open Pop-ups and redirects.
• Toggle it off so that it reads "Blocked," which is the recommended state.

Chrome will now block unwanted windows and the aggressive redirect chains some ad networks use. A small bar appears at the bottom of the page when a pop-up is blocked, so you can still allow one manually if a site genuinely needs it.

Stop Website Notification Pop-ups (Push Notifications)

If pop-ups keep arriving even when no browser is open, they are website push notifications, not browser pop-ups, and the blocker above will not touch them. You have to revoke the notification permission per site.

• In Chrome: tap ⋮ > Settings > Site settings > Notifications, then switch off individual sites listed under "Allowed," or turn the whole category off.
• In Samsung Internet: open Menu > Settings > Sites and downloads (or Privacy dashboard) and review per-site permissions, removing notification access for any site you no longer want alerts from.

Turn Off App Pop-up Notifications on One UI

Some installed apps push banners or floating heads-up alerts that pop over whatever you are doing. One UI lets you keep an app's notifications but stop them from popping on screen, or silence them entirely.

• Open Settings and tap Notifications.
• Tap App notifications (or "Advanced settings" on some builds) and select the app that is bothering you.
• Turn the app's notifications off completely, or open its notification categories and disable the Pop-up style or banner option so alerts stay silent in the panel.
• As a shortcut, when a pop-up appears, press and hold it, then tap the gear icon to jump straight to that app's notification settings.

Stop Full-Screen Ad Pop-ups from a Rogue App

Full-screen ads that take over your home screen, especially when no browser is open, are the work of a rogue ad-injecting app, usually bundled with a free flashlight, cleaner, wallpaper, or game app. The goal here is to find it and remove it.

Find the Culprit

The instant an ad appears, open Recent apps (the multitasking key or gesture). The offending app often sits on top of the stack. Alternatively, go to Settings > Apps and sort the list by Most recent to spot anything you installed right before the pop-ups began.

Revoke "Appear on Top"

Rogue apps need the overlay permission to draw ads over other apps. Go to Settings > Apps > tap the three-dot menu (or filter) > Special access > Appear on top (labelled Display over other apps on some One UI builds) and turn it off for any app that has no reason to draw over your screen.

Boot into Safe Mode and Uninstall

Safe Mode starts the S10 with only pre-installed apps running, which confirms whether a downloaded app is to blame. Press and hold the Volume Down and Side keys together, then touch and hold the Power off icon and tap Safe mode. If the pop-ups vanish in Safe Mode, a third-party app is the cause. Restart normally and uninstall the most recently installed or updated app, retesting after each removal.

Run Play Protect and Reset Your Ad ID

Finish by opening the Play Store, tapping your profile icon, selecting Play Protect, and running a Scan to flag known harmful apps. To cut down on personalized ads in general, open Settings > Privacy (or Google > Ads) and delete or reset your Advertising ID.

Manage Smart Pop-up View (One UI Chat-Head Bubbles)

Smart pop-up view is a One UI feature unique to Samsung phones like the S10. It shows incoming messages as small floating chat-head icons that expand into a pop-up window when tapped. Handy for some, distracting for others, and easy to mistake for unwanted pop-ups.

• Open Settings and tap Advanced features.
• Tap Smart pop-up view.
• Toggle off the apps you do not want appearing as floating bubbles, or turn the feature off entirely.

Disabling it stops the message bubbles without affecting your regular notifications.

Still Seeing Pop-ups? Troubleshooting

• Check the right browser: if the pop-up came from a website, make sure you set the blocker in the browser you actually used. Samsung Internet and Chrome are configured separately.
• Clear cache and site data: a site that already has lingering permissions can keep nagging. Clear the browsing data and cookies for that site, then revoke its notification permission again.
• Confirm with Safe Mode: if pop-ups appear outside any browser, reboot into Safe Mode (Volume Down + Side key). No pop-ups there means a downloaded app, not the system, is responsible.
• Keep the device updated: install the latest One UI security patches under Settings > Software update, since some ad-overlay exploits are patched at the OS level.
• Factory reset as a last resort: if a stubborn rogue app survives uninstall attempts, back up your data and perform a factory reset to wipe it cleanly.
• Expect label variance: One UI renames menus between versions, so if "Privacy dashboard" or "Special access" is not where described, use the in-Settings search bar to locate the equivalent option.

Test How Pop-ups Render on Real Samsung Devices

If you build or test mobile apps and websites, it helps to verify how pop-ups, overlays, and push notifications appear across different Samsung Galaxy models and One UI versions, since behaviour varies by device and Android build. With TestMu AI's Real Device Cloud, you can run a live session on real Samsung handsets straight from your browser to confirm your pop-up blocking, notification prompts, and overlays render correctly for end users.

Frequently Asked Questions

Why does my Samsung Galaxy S10 keep showing pop-ups?

Pop-ups on the Galaxy S10 usually come from one of four sources: web pop-ups and redirects in a browser, website push notifications you accidentally allowed, app heads-up notifications set to pop on screen, or a rogue ad-injecting app showing full-screen ads. Identifying the source tells you which fix to apply.

How do I block pop-ups in the Samsung Internet browser?

Open Samsung Internet, tap the Menu (three lines, bottom-right), go to Settings, then open Sites and downloads on older One UI builds or Privacy dashboard on newer ones, and toggle Block pop-ups on. Samsung Internet also has an Ad blockers menu where you can install a content blocker for heavier ad removal.

How do I stop pop-up ads caused by an app on my S10?

Find the culprit by opening Recent apps right after an ad appears, or by sorting Settings > Apps by most recent. Revoke its Appear on top permission under Settings > Apps > Special access, then boot into Safe Mode to confirm a third-party app is responsible and uninstall the most recently added one. Finish with a Play Protect scan.

What is Safe Mode and how do I use it to find the app causing pop-ups?

Safe Mode starts the S10 with only pre-installed apps running. Press and hold the Volume Down and Side keys together, then touch and hold the Power off icon and tap Safe mode. If the pop-ups stop in Safe Mode, a downloaded app is the cause, so restart normally and uninstall the most recently installed or updated app.

How do I turn off Smart pop-up view on the Galaxy S10?

Open Settings > Advanced features > Smart pop-up view and toggle off the apps you do not want appearing as floating chat-head bubbles. This One UI feature shows incoming messages as small pop-up icons, and disabling it per app stops those bubbles without affecting your other notifications.

Does blocking pop-ups also stop website notifications?

No. The pop-up blocker only stops new browser windows and redirects. Website push notifications are a separate permission you have to revoke under your browser's Site settings > Notifications. You may need to turn off both to stop every kind of browser-driven pop-up.
