I have with my huawei mate 10 lite the problem that constantly advertisement comes (also at the start screen) (Pop - up advertisement). Can someone tell me how to fix this?
Maybe install an adblocker.
Yes, just my problem is the pop-up advertising that just pops up on the start screen…
Do you know from which app the advertisement comes? If so, turn off permission for notifications, pop ups, etc.
Do you have apps like 360 Security or Security Master installed on your phone? They like to show such advertising. If I uninstalled, your Mate 10 Lite has its own "security" and garbage collector.
If you have not installed something, I would examine the unknown apps you have on the phone by reading the bad reviews in the Play Store.
