Windows Camera app fro Windows 10 has picked up an update, and while its not a major one, there is atleast one noticeable bug fix this time.
After the previous update, many users(including me) reported that there were autofocus and tap-to-focus issues in the app. With the new update(2016.1130.11.0) the focussing issues have been mitigated.
Grab the update from store and see for yourself.
