Annoying ads on your Samsung Galaxy S9 Plus can come from several sources, including the operating system, apps, and browsers. To stop ads effectively, you need to adjust device settings, manage your advertising ID, control app permissions, and configure opt-outs where possible. This guide provides an evergreen, step-by-step approach to reducing interruptions and limiting ad tracking without breaking core functionality. It covers Android system settings, Samsung-specific options, and best practices for individual apps and browsers.
Understanding where ads come from on Samsung S9 Plus
Before attempting fixes, it helps to identify likely sources. Ads can appear in app content, web pages, notification shade, and system prompts. Common causes include ad-supported apps, enabled ad personalization, a misbehaving app, or a compromised browser with aggressive ad networks. On Android, an advertising ID is used for ad targeting across apps, and you can limit or reset it to reduce cross-app profiling. Knowing the source narrows your approach and prevents unnecessary changes that could affect app behavior or device performance.
How to stop ads on Samsung S9 Plus: step-by-step
Work through these steps methodically to reduce ads at the system and app level. Some changes are quick, while others require deeper review. Prioritize safety and avoid unverified apps or risky settings that could compromise security or void warranty. When possible, update apps and Android to ensure you have the latest features and bug fixes. If ads persist after initial fixes, revisit app permissions or consider safe modes to identify problem apps.
Check app notifications and permissions
Apps with notification permissions can display promotional alerts that look like system ads. Open Settings, tap Apps, review installed apps, and check notification and permission settings. Turn off unnecessary notification permissions and restrict background data for apps that do not need it. This reduces the number of ad triggers while keeping core functions intact.
Reset advertising ID and opt out of ad personalization
Android uses an advertising ID to deliver personalized ads across apps and websites. Resetting this ID and opting out of ad personalization can reduce tracking and ad relevance. In Settings, go to Google > Ads, toggle Limit ad tracking or opt out, and tap Reset advertising ID if you prefer a fresh identifier. Note that this mainly affects ad networks and personalized ads; some non-personalized ads may still appear based on contextual signals.
Manage Samsung and Google Ads services
Samsung and Google provide ad-related services that can be adjusted in Settings. Review Ads settings in both Samsung and Google apps, and disable unnecessary ad features where options exist. Be cautious with system services and avoid disabling core components that could affect device stability or app functionality. If you are unsure, search official Samsung support for guidance on specific toggles before changing them.
Update apps and Android
Keeping your device and apps up to date can fix bugs that cause unwanted ads. Open Play Store and Settings to check for updates, and install security patches when available. Updates often include fixes for misbehaving permissions, SDK improvements, and better ad controls. Regular maintenance helps prevent regressions and keeps your experience smoother.
Use safe mode to isolate problematic apps
If a particular app is responsible for intrusive ads, safe mode can help identify it. Press and hold the power button, press Power off, then press and hold Safe mode to start. In safe mode, third-party apps are disabled. If ads disappear, an installed app is likely the cause. Uninstall recently added or suspicious apps, and check app reviews before installing new ones.
Clean up browsers and web ad scripts
Web ads are often managed by browsers and their extensions. Use reputable browsers that support ad blocking and enhanced tracking protection. In your browser settings, enable privacy features, block third-party cookies, and consider adding content blockers. Avoid unknown browser extensions that can inject ads or redirect traffic, and reset browser settings if you encounter persistent web ads.

Long-term best practices to minimize ads
To keep ads under control, adopt habits that reduce exposure and limit tracking. Only install apps from trusted sources, review permissions regularly, and avoid granting notification access to non-essential apps. Use browsers with strong privacy features and consider reputable ad blockers where appropriate. Periodically check ad settings and reset your advertising ID if you notice increased ad targeting. These practices help maintain a cleaner experience over the life of your device.
When ads may indicate deeper issues
In some cases, persistent ads can signal malware, adware, or a compromised app. If you see unexpected pop-ups, redirects, or suspicious installs, stop installing new apps, run security checks, and consider a factory backup and reset. Avoid sideloading APK files from unknown sites. For ongoing issues, contact Samsung support or a trusted technician to inspect the device safely.

Core steps include resetting your advertising ID, disabling unnecessary notifications, reviewing app permissions, keeping software updated, and using safe mode to identify problematic apps. Web browsing hygiene and cautious app choices further lower ad exposure over time. By following these evergreen practices, you can maintain a smoother, less interrupted experience on your device.
