I'm designing an mobile-web-app (ie: not a native app) for touchscreen smartphones.
When you add a search input, do we need to add the search button (for processing the search) or use the one present in the keyboard? If user perform a search, he will
- tap on the search field
- The keyboard appears, he taps his search terms
- When he's finished he taps "go" on the keyboard.
Is it necessary to add a search button (if keyboard doesn't show the "go" button for example)
Do all touch devices have the "go" button?
