I’ve tested the Google HDR+ camera APK on my Samsung Galaxy Note 8 and S8(Snapdragon) for about a week, they both work flawless and bring additional HDR mode to non-Pixel phones. If you need extra 1-2 stops of dynamic range on your photos, Google HDR+ mode will give you exactly that(and make sure you have it on when using the camera!), bright areas exposured correctly.
For now, this APK file is ONLY compatible with Snapdragon Samsung devices such as the T-Mobile Note 8 or S8 I have. You can try it anyway though, I don’t think the file can hurt anything in any way since this is from XDA forums where people double-check others work for bugs or spyware. You can use this APK with ANY Snapdragon Samsung, LG, or any other Android smartphone (most likely). Exynos is NOT supported unfortunately so if you have international model of S8, you won’t be able to use it.

(Make sure to turn “HDR+” mode ON at all times. 95% of the time HDR+ will give you better photos with the Google Camera app. HDR+ will also enhance low-light photos and remove noise without affecting the image.)
(Only thing missing? We need the Portrait mode from Pixel 2!)
(This Google Camera app is ONLY recommended photos. Videos are limited to 1080P and you will find much better video recording on your native camera app.)

How to Install APK Files
You will need to make sure Unknown Sources is checked ON in Settings to install APK files. We do recommend you to use a file explorer app such as ES File Explorer, available on the Play Store for free, to install these apps.
