Random pop-ups, ads, or strange notifications are almost always caused by a single app, a website you visited in Chrome, or a setting on your phone. The good news: this isn't a virus and you don't need a new phone.
First — think about what changed
A few questions that usually point to the cause:
If the answer to either of the last two is yes, the most likely fix is uninstalling that app or clearing your browser.
Find the app sending the pop-ups
Check your most recently used apps
- Settings → Apps → See all apps.
- Tap the three-dot menu (top right) → Sort by → Recently opened.
- Look for anything you don't remember installing — names like "Cleaner," "Booster," "Optimizer," or unrecognized utilities are common culprits.
Check your notification history
- Settings → Notifications → Notification history.
- Turn Notification history on if it isn't already.
- Scroll through recent notifications and see which app sent the pop-ups.
Fix the source
Turn off Chrome pop-ups
- Open Chrome → three-dot menu (top right) → Settings.
- Scroll to Site settings.
- Tap Pop-ups and redirects and turn it off.
- Back in Site settings, tap Ads and make sure it's blocked.
Clear Chrome's cache
- Settings → Apps → Chrome.
- Force stop → OK.
- Storage & cache → Clear cache.
Turn off notifications from a specific app
Once you've found the offender:
- Settings → Apps → [the app] → Notifications.
- Turn off the notifications you don't want.
Uninstall the app
- Open the Play Store.
- Search for the app.
- Tap Uninstall.
