Thanks for your response. Indeed, deleting is easy (although 1 or 2 refused deleting). Seems Opera for Android doesn't offer search engine editing also. Nothing but the desktop app. Oh well...

Hello. I've got Opera Mini v17 on my 5.0.1 Samsung phone.

How do I edit search engines? How do I delete any of them? Adding search engines is kinda straightforward, but how do I edit afterward?

I've got Wikipedia as one of my search engines, but the problem is that it's not the English version of Wikipedia. Just need to change two letters at the beginning of the url.

Thanks
