I've been using duckduckgo exclusively for a year now on all my devices and I'm loving it.
The whole point of a search engine is to give you what you're looking for, and ddg delivers. If I ever need to Google something, I'll use !g query. You can make it look really nice also by changing it from the Default theme to Basic.
I didn't realize you could do this on Android until I read this. I've been using DDG on desktop for a year or so. The trick is to visit DDG before you try to change your search engine. Otherwise, it's not listed as an option.
If you put "!g" at the start of your search, DDG automatically redirects you to the search result in google.
I've been using DDG as my search engine for about 2 1/2 years now, and I find absolutely no reason to go back to Google other than location search, and DDG proxies that easily.
