In case if the application is essential for you then check for the availability of the premium subscription option from the app menu or account settings. In some applications, ads will be blocked automatically when you are using Pro version or paid accounts. If Pro version or paid service does not apply to the app you are using, then you need to eliminate the application from your device to eliminate the annoying ads issue.
If you could not be able to find the apps that display ads on your device while unlocking then install an ad detector or ad blocker app from Google PlayStore and ensure they are reliable from the user reviews. Launch the ad detector app on your device to know the app that shows advertisements while unlocking the device.
When the Adware app is detected, go to PlayStore and then uninstall the application from your device. If you have installed the ad blocker app on your device, launch the app and enable ad block mode to avoid the unwanted ads and continue using the app. For any further information on How to Stop Pop Up Ads When Unlocking Phone, get in touch with our experts.
