The Google Pixel’s camera is one of the best smartphone cameras on the market, partially thanks to Google’s proprietary HDR+ image processing. Put simply, HDR+ takes multiple underexposed photos and combines them, reducing image noise in the process (you can read more about it here). But even when the Google Camera was sideloaded onto other devices, HDR+ remained disabled.
A Ukrainian developer on 4PDA named ‘B-S-G,’ presumably a Battlestar Galactica fan, has created a modified version of the Google Camera 4.4 APK bundled with Android O DP3 (not the version just released on the Play Store).
Google Camera with HDR+ unofficially ported to Snapdragon 820, 821, and 835 devices was written by the awesome team at Android Police.
