A few weeks back the Stock Google Camera was ported to devices with a Snapdragon 835 processor. The ported app was also working with Snapdragon 820 and 821 devices. This brings HDR+ to these devices which drastically improved dynamic range on photos taken with my Galaxy S8. This meant there was more detail in the shadowy areas. Some low light situations turned out better with Google's camera as well.
The ported camera is now compatible with many more devices including those devices with Snapdragon 4xx or 6xx processors. Some are reporting that it works with some Xiaomi devices including the Redmi Note 3, and Redmi Note 4. The latest version also includes lots of bug fixes and a zero shutter lag fix. You can grab the updated camera from the link below.
