On the bar at the top of the camera app, select the 3rd option (looks like an iPhone home button) and move the slider all the way up until it reaches the infinity sign.
Only distant objects are in focus when I use infinity focus. Close and mid range objects are blurry. I think hyperfocus photos are only possible with Refocus
It's almost impossible to get everything in focus with the phone's camera because the single gperture is really wide (f/2). You need a smaller aperture for it. Best work around is Refocus as mentioned above.
