Google Pixel devices, when launched, had the best camera even better than the iPhones and even after a year they still compete with these years’ flagships. The most highlighting feature of the Pixel was its HDR Plus mode which made a great difference as well as took far less time this thus tells us how good its image processing was.
However, now you can have its camera app which is ported by a talented XDA member who goes by the name B-G-S, the developer has ported the camera app for devices running on Qualcomm Snapdragon 820, 821 and 835 chipsets. Moreover, this port also contains the most important HDR Plus mode along with Zero-Shutter-Lag, feature, which is helpful in action shots.

Moreover, a stable bug-free port is in the cards specifically for the One Plus 3T. Along with that, the app now also gains RAW support so, you can adjust whatever you want in a desktop software giving you full control over the image. Furthermore, for the HDR Plus mode to work, you have to select it from the experimental tab, where also resides the RAW support.
The HDR Plus mode also now gains the burst-frame count ability along with buffer size for it. Also, make sure before installing this version of the port if you have any earlier ones make sure you clear the data and cache, according to the developer.
Another thing to note is that if you do not have camera2 API, this port will not work for you, appending to that list is phones with the following CPU’s that’s Kirin, MediaTek, and Exynos.
