For those Roku users who don’t have the company’s HDMI Streaming Stick, you now have a chance to do searches on your smartphone with the upcoming update for Roku 3 devices. The rollout is expected to wrap up by April 22. So if the update hasn’t come your way, just wait a bit. Those using other models will also be getting the update in the coming weeks. And for the time being, be a bit more patient and suffer through typing with the remote.
