Hi! I understand the OKOK·International app is causing incessant ads on your Android 10 phone, making it very difficult to use. That sounds really disruptive. Let's work through this carefully to fix it without immediately jumping to a factory reset if possible.

To start, have you already tried uninstalling and reinstalling the OKOK·International app? Sometimes a fresh install can clear bugs related to ads.

If you haven't:

1. Go to your phone's Settings > Apps > OKOK·International.
2. Tap Uninstall.
3. Restart your phone.
4. Reinstall the app from the Google Play Store.

If uninstalling doesn't help and ads keep popping up even when not using the app, the ads might be coming from unwanted permissions or additional adware. Here's what you can do next:

1. Check app permissions:
- Go to Settings > Apps > OKOK·International > Permissions.
- Revoke any permissions that seem unnecessary, especially anything related to "Display over other apps" or "Draw over other apps," as these allow intrusive ads.

2. Check if there are any other recently installed apps that might be related to the problem and consider uninstalling those apps as well.

3. Clear cache and data for OKOK·International:
- Settings > Apps > OKOK·International > Storage > Clear Cache and Clear Data.

4. Install an ad-blocker or antivirus app from a reliable source like Google Play to scan and block intrusive ads or adware on your device.

If after these steps the ads persist heavily and impact the phone's usability severely, then a factory reset might be the last resort option to clean out any persistent malware or adware.

Before factory resetting, make sure to back up your important data since a reset will erase everything on your phone.

Does this approach make sense to you? Have you tried any of these steps so far? We can take it from there.
