Bugs:
Here is the fix for purple colour on exposed areas on S7 Exynos. I only fixed Pixel XL device, so use that. As a side affect noise increased... But well lit shots are very sharp in portrait mode now.
You can enable HDR+ for front, but it is very unstable. Success depends on exposure somehow. If it hangs, you have to restart the app to take hdr shots again.
Reenabled medium,very high etc hdr settings. Not that I see any difference in quality, but some of you asked for it... Non default settings will make portrait mode less stable for sure.

Thread: https://forum.xda-developers.com/galaxy-s7/themes/google-camera-portrait-mode-t3736859
Bugs:
Changes vs. V3:
-front cam HDR+ workaround for S7. Still to be tested in very bright conditions. Turn on "HDR+ front camera fix" if you have an S7.
-front cam: normal pics in auto HDR+ mode are saved now
-front cam: improved non-HDR+ quality
-added a custom auto-exposure mode for HDR+ (only HDR+, so not for portrait). It is called "Slow shutter" because it will decrease shutter speed as much as possible (1/10 secs on S7) in bad light. The result: much lower ISO and noise. Of course fast moving objects will probably get blurry more easily. Only tested this on S7, on other devices it might need some tuning.
5th version:
Download:https://drive.google.com/file/d/1TLi5mt9DDlraF5ncE4SbV7lcfHpeqv4X/view?usp=sharing
Thread: https://forum.xda-developers.com/galaxy-s7/themes/google-camera-portrait-mode-t3736859

Changes vs. V4:
-added more shutter options. Selecting "Stock camera2 api" will get rid of rainbow effect, but dynamic range is poor, because camera can't underexpose fast enough if auto shutter control is on.
-added antibanding modes. Works up to 1/149 sec shutter speed. Only select 50hz or 60hz in case of banding problems, because it can cause suboptimal shutter speed otherwise!
-denoise strength for HDR+ and portrait. For front cam you need to select about 2-300% to really see the difference. Back cam is much more sensitive to this setting.
-HDR+ dynamic range control (called Underexposure multiplier). Reduce below 100% to decrease rainbow effect.
-added Samsung specific metering modes. To enable touch to expose, select "Controlled by GCam".
-added Samsung Live HDR mode. Adds some dynamic range to modes where HDR+ is not available like zero shutter Portrait mode. No Rainbow effect in HDR+ mode if this is selected, but noise is too much unfortunately!
-you can enable HDR+ for Portrait mode by disabling "Portrait ZSL mode". Better dynamic range, custom shutter control, but no zero shutter lag.
-custom white balance. I set greens to 96% to get rid of the greenish look where I sit right now, but it is a matter of taste probably.
-modified HDR+ quality settings. Choose "Very high" if you were using "Medium" before (unstable for me). The recommended "Default" setting is the same as before, it is somewhere between medium and high.

Thread: https://forum.xda-developers.com/galaxy-s7/themes/google-camera-portrait-mode-t3736859
Changes vs. V5:
-fixed bug which caused hdr+ shot failure sometimes!
-attempted to fix HDR+ portrait mode (can be activated by disabling portrait ZSL mode).
-added some description to "HDR+ parameters". For example: 8/10 burst, 1500 MB means: HDR+ operates with 8 shot bursts. Portrait mode (ZSL) operates with 10 shot bursts at most. Estimated total memory usage: 1500 MB (including camera2 api buffers).

Thread: https://forum.xda-developers.com/galaxy-s7/themes/google-camera-portrait-mode-t3736859
Changes vs. V7:
-made Pixel 2017 ZSL config work on our device. I had to disable reprocessing, and smart touch to focus. Also some experimental Pixel specific features like hybrid AE cannot work on our device, so don't expect Pixel like quality. Basically the only change versus Nexus 6 config is that if the HDR+ switch is set to the middle, you will have zero shutter lag HDR+ instead of auto HDR+. ZSL HDR+ is the same thing we already had before in portrait mode. So less dynamic range, and more noise in low light because slow shutter mode is not available. However it is much better in good/medium light if you make photos of unpredictable things like kids, because it processes images already taken in the background. In low light, or high contrast scenes please use Enhanced (nonZSL) HDR+! In "HDR+ parameters" setting I recommend using one of the Pixel 2017 options, because they should be more stable regarding memory leak. "High", "very high" and even "default" leak memory if pixel 2017 config is used.
-BSG mod settings moved to Advanced settings.
-you can now use portrait mode without zoom
-portrait mode pictures can be saved directly to DCIM/Camera. However: the built-in gallery can get confused by this, so I recommend using Google Photos instead (camera.use_photos must be enabled in dev settings). And even more importantly: before V8, the built-in gallery in GCam will delete all portrait pics from DCIM/Camera if you delete a single portrait pic from DCIM/Camera!!!! I patched this in V8, but if you were to go back to a previous version you can get into trouble easily!!!!
-you can modify some internal denoise settings. Unfortunately I couldn't find a combination which improves quality in all situations, but feel free to play around with them. Turn on the switches to apply changes.
-fixed a rare background battery consumption issue.
-camcorder fixes: front cam is working now, enabled optical stabilization, Samsung HDR can be turned on for video.

Thread:
https://forum.xda-developers.com/galaxy-s7/themes/google-camera-portrait-mode-t3736859
Changes vs. 8.2:
Here is some more shutter modes added. Slow shutter X2 goes to 1/5 secs. X4 and X8 go even slower but they are completely unstable, I get a camera error after a few shots.
Slow motion is fixed for S7 (I might have broke the app for other devices completely by doing this), turn off live hdr if in 240 fps mode or the lights will go off after a few secs:)
This is kind of a half finished release...

I've made also more user friendly versions here https://forum.xda-developers.com/galaxy-s8/themes/apps-googles-cameras-ports-t3778837

By the Way: @miniuser123 reseased V8 and asked S8 Oreo users to provide Logs to improve HDR+ for our device on Android 8. So please if you already have Oreo running on your Phone, provide a Log and mark miniuser123 ( @miniuser123) in your post.
How to provide Logs (you don't need ADB to set this up)

Bonus!
You can also use AR Stickers if you are on Oreo
Install AR Core first https://github.com/google-ar/arcore-android-sdk/releases/download/sdk-preview2/arcore-preview2.apk
Then AR Stickers https://drive.google.com/file/d/1Z1KgNE5OhkLhbwy-XrGWCzJc2AcK0Ocz/view
Force close Gcam and re-open it!
Done!

Note that those bugs reports are referred to Galaxy S7 so they may not be valid for Galaxy S8.

Also keep in mind that every time there's an update you have to clean install the app or at least wipe data's app
Every time you change settings in the app you have to close it from recent panel(or maybe better directly force close) and reopen the app to apply new setting


Because many users have problems with this app i will share my working configs in the attachment working on Oreo CRAP/CRB7
for v7. If you want to try the Pixel 2017 ZSL in v8.2 the settings are shown below


https://photos.app.goo.gl/I0bNgViMtX9sWFOX2
(Photos captured with google camera in various light condition)

Seriously i went back to Nougat, best decision ever google cam now is pretty stable and fast. No more waiting to take next photo. lol and it's cooler too no more heat up like crazy and wasting battery life.

For first timer s8 user, Highly recommended S8 optimized version from @IDan1109

Otherwise check these out :
Because this version was made for S7 user, first thing u have to do is go to camera setting which is located at top left > developer setting > Disable "camera.enable_micro" immediately. Now you can freely try any setting with trial and errors. After tons of test i highly recommend advanced user, uninstall your 8.2 instead of replace 8.2 with 8.3b. reinstall your app and try new settings instead of stacking it together. Trust me clean install always better.
(for example test your Slow shutter result shutter time if it does not give 1/3s 1/4s each shot, your version of gcam is corrupted)
updated v8.3B
This is my latest config stable with v8.3B. Optimized after alot of experiments.
Now you can capture best lowlight picture and still give you finest detail possible.
First, pick HDR+ enhanced to force hdr to capture lowlight with less noise.
disable flashlight. (only use it if you forced to do, gcam will shot with huge yellow gained but can be edit it back to natural color in lightroom or pts)

*Enter setting > First page > "Slow Shutter x2" or X4 (kinda gimmick anyway but switch to faster shutter speed if u wanna take fast moving object),
Antibanding = Controlled by GCam (60hz give tons of noises),
75% underexposure multiplier NoneZSL HDR+,
100% denoise back and front, Metering Mode = Center (Gcam will allow u to touch to focus.)
Live HDR = Disable/enabled (higher contrast but a bit blurry in the dark area, so only enable it only if u have good light source.
(personaly i left this disabled)
Portrait ZSL mode = enable, Portrait Zoom = disable (turn on if u want closer look).
HDR+ White balance = no change.
Tuning Back cam = Taimen
Tuning Front cam = Bullhead
*Advanced menu > HDR+ = Fast Stable or faster, Config camera HDR+ = Nexus 6 HDr+ Auto (less noise),
turn on = auto HDR+ front camera, ...etc
Turn on (off all those fixes, with exynos in it if you're snapdragon S8)
The rest in this page can leave it there, or set it to your liking, not important.

* Developer settings >
Disable Camera.use_photos and cameraprogress_overlay
Disable "camera.enable_micro"
_______
wanna get rid of rainbow effect ? Turn on Live HDR Samsung (this will introduce noise but the rainbow gone)
Trick to take picture in daytime is use your finger to focus on the dark area (not darkest to avoid blowout the highlight, then wait for HDR+ to work the magic. (u can lower the highlight in LightRoom later on anyway but byebye rainbow)

For future update you should go check it here : the owner of this page rapidly update all the new versions which just came out and even translate it to english.
https://www.celsoazevedo.com/files/android/google-camera/
For example this guy : https://www.celsoazevedo.com/files/android/google-camera/f/changelog107/
took v8.2 and modified it then add more shutter speed options, too bad from my test it's not optimized for s7/s8. alot of crash but once u get working setting it's not better in term of image quality + stablility VS v8.2 miniuser123

For some reason, I can't get Portrait Mode to work, Could you share what settings you are using?
Also, I feel like HDR+ is shooting way faster than when I tried with other versions of the app (now it's instantaneous.) I am not sure if it's working or not :D

Right, that's what I tried as well, but it still doesn't work - I get a black screen. I tried rebooting, but it didn't help :/

All I did was to turn on the portrait mode switch in the settings and then go out of the camera app and then back in again. After that when swiping from left to right the portrait mode appeared. I did not change any other settings at all.

front camera in working now!! big thanks to @miniuser123
Purple front cam fixed for exynos. Clean install please!

https://drive.google.com/file/d/1vRcLKVq8qbTL1KbMajPCEROMmnnod1va/view?usp=sharing

Camera api2 reports incorrect value for COLOR_FILTER_ARRANGEMENT for front cam, so I overrode it.

Still to enable hdr+ for front cam.

Known bug: when you exit settings for the first time, you get a black screen. Force close the app, and start again, it will be ok second time.

Snapdragon users should try to set "Fix black level Front camera" to 64 based on info by TheOddTaco (thanks to him for helping me).

Also some experimental Pixel specific features like hybrid AE cannot work on our device, so don't expect Pixel like quality. Basically the only change versus Nexus 6 config is that if the HDR+ switch is set to the middle, you will have zero shutter lag HDR+ instead of auto HDR+. ZSL HDR+ is the same thing we already had before in portrait mode. So less dynamic range, and more noise in low light because slow shutter mode is not available. However it is much better in good/medium light if you make photos of unpredictable things like kids, because it processes images already taken in the background. In low light, or high contrast scenes please use Enhanced (nonZSL) HDR+! In "HDR+ parameters" setting I recommend using one of the Pixel 2017 options, because they should be more stable regarding memory leak. "High", "very high" and even "default" leak memory if pixel 2017 config is used.
    -BSG mod settings moved to Advanced settings.

    -portrait mode pictures can be saved directly to DCIM/Camera. However: the built-in gallery can get confused by this, so I recommend using Google Photos instead (camera.use_photos must be enabled in dev settings).

    Otherwise check these out :
    Because this version was made for S7 user, first thing u have to do is go to camera setting which is located at top left > developer setting > Disable "camera.enable_micro" immediately. Now you can freely try any setting with trial and errors. After tons of test i highly recommend advanced user, uninstall your 8.2 instead of replace 8.2 with 8.3b. reinstall your app and try new settings instead of stacking it together. Trust me clean install always better.
    (for example test your Slow shutter result shutter time if it does not give 1/3s 1/4s each shot, your version of gcam is corrupted)
    updated v8.3B
    This is my latest config stable with v8.3B. Optimized after alot of experiments.
    Now you can capture best lowlight picture and still give you finest detail possible.
    First, pick HDR+ enhanced to force hdr to capture lowlight with less noise.
    disable flashlight. (only use it if you forced to do, gcam will shot with huge yellow gained but can be edit it back to natural color in lightroom or pts)

    *Enter setting > First page > "Slow Shutter x2" or X4 (kinda gimmick anyway but switch to faster shutter speed if u wanna take fast moving object),
    Antibanding = Controlled by GCam (60hz give tons of noises),
    75% underexposure multiplier NoneZSL HDR+,
    100% denoise back and front, Metering Mode = Center (Gcam will allow u to touch to focus.)
    Live HDR = Disable/enabled (higher contrast but a bit blurry in the dark area, so only enable it only if u have good light source.
    (personaly i left this disabled)
    Portrait ZSL mode = enable, Portrait Zoom = disable (turn on if u want closer look).
    HDR+ White balance = no change.
    Tuning Back cam = Taimen
    Tuning Front cam = Bullhead
    *Advanced menu > HDR+ = Fast Stable or faster, Config camera HDR+ = Nexus 6 HDr+ Auto (less noise),
    turn on = auto HDR+ front camera, ...etc
    Turn on (off all those fixes, with exynos in it if you're snapdragon S8)
    The rest in this page can leave it there, or set it to your liking, not important.

    * Developer settings >
    Disable Camera.use_photos and cameraprogress_overlay
    Disable "camera.enable_micro"

    wanna get rid of rainbow effect ? Turn on Live HDR Samsung (this will introduce noise but the rainbow gone)
    Trick to take picture in daytime is use your finger to focus on the dark area (not darkest to avoid blowout the highlight, then wait for HDR+ to work the magic. (u can lower the highlight in LightRoom later on anyway but byebye rainbow)

    For future update you should go check it here : the owner of this page rapidly update all the new versions which just came out and even translate it to english.

    took v8.2 and modified it then add more shutter speed options, too bad from my test it's not optimized for s7/s8. alot of crash but once u get working setting it's not better in term of image quality + stablility VS v8.2 miniuser123

    and for anyone else who needs working settings for 8.2 on S8+ Oreo CRB7

    Metering mode is set to centre weighted! It works well on Portrait shots. And if your image is darker try changing it back to GCam.

    I also have Face Retouching enabled in Portrait mode!

    Try playing with denoise and tuning if you don't like the output. Force close the app after you made the changes to settings/configurations.

    Btw i ported back Arthur's version of Gcam (Still based on miniuser) i think i'm getting closer to fix pink potrait of arnova's version. My pc is going to die soon(HDD) so don't expect updates from me.
    Make sure before install this to:
    -uninstall your current version of Gcam
    -from smart manager clean up the memory (YES it's needed beacuse after i tried a lots of different verisons of Gcameras i messed up something more then the app cache itself)
    -install the app. DONE!
    you don't need to set any settings on this apk it should work fine at the first setup.

    I've only tried it on OREO
