I have a cool trick to open youtube videos on the app instead of opera mini. You have to edit the link on address bar and add "vnd.youtube:" string. Example https://m.youtube.com/watch?v=WWfz3Yri_o4 change to vnd.youtube:WWfz3Yri_o4 and enter. Done. Happy watching

You mind share the link?

Another problem is that I can't share youtube videos to facebook from youtube website. In any youtube videos, I click youtube share button (share to facebook) then it says "Something went wrong"
but all other browsers are full ok to share youtube videos to facebook.
Fix this ASAP

I've tried to share youtube videos to facebook and works fine. Tried on data saving extreme/high/disable and disable ads on/off.

You can paste your page link to a 'web to pdf' online website to get your pages printed.

There is no way you can change default search engine BUT it is possible to add other search engines. First off you have to change data saving to 'extreme' then go to any search engine site you'd want to add, let's say bing.com then press and hold the empty search box a window pops out and click on 'add search engine'. That's it. Switch back the data saving options and there will be a new option in the search box.

I use latest version of opera mini android and I assume ios has similar options like mine.
