Issue with ads

[Android Central Question]

Recently I have heard from two my family members which owes Huawei P20 and P20 Pro. Issue is common: without any reason random ads has been poping out all the time. Like can't even pick up phone when its ringing!
Can anyone advise. Thank you in advance.

This happened to a friend's tablet too. Tried to delete all third party apps but it still persisted. In the end the only thing the only thing that worked was resetting the device.

You can go straight to step 3 or you can try these steps in sequence.

1. Remove all user installed apps
2. Find instructions for clearing cache in recovery mode.
3. Reset and reInstall apps. But don't do the auto reinstall of apps, re install the apps manually.
