The Essential phone was one of the most important launches of 2017, but one of the biggest disappointments at launch was the camera. Since launch, Essential has been making steady improvements to the app, and they are back at it again.
Among the improvements are an update to the camera roll which will allow you to more easily find media of different types with dedicated buttons for things like Slo-Mo, 360 shots, and Burst mode shots. They have also made improvements to 360-degree videos by allowing you to save, share, and edit them as Tiny Planets. And there is a very handy update to burst shots by saving them as a group. Essential also mentioned various bug fixes and improvements to stability.
Overall, you should be getting a more organized experience. The update is live now for the Essential phone via the Play Store.
