"Opera mini has ads it self included.

May be is malware from some infected library, but even with adblocker activated show ads image/video, with timer (versions tested: v90.1.2254.77167, v92..[apkmirror repo] v99 from Google Play).

Older versions, such as v62, v75, v80, and v85.0.2254.74549 from the apkmirror repository, do not display ads.

(Tested on Wi-Fi networks with an adblocker enabled [Pi-hole]; no ads are displayed with any version, but with the [Pi-hole] adblocker disabled, ads are displayed from version 90 up to the latest version 99 from Google Play; this occurred both with and without the Opera Mini adblocker).

P.S.: One of the ads displayed an icon (i), and when clicked, it opened a page called Opera ads.
