[Samsung Galaxy S8 Themes, Apps, and Mods] MarkerBeanXDA:
This is for those who does not really want all the fancy features that are present in Stock Touchwiz ROM and prefer to only have what is on Stock Android or Pixel-like experience.

All credits goes to the creator of each mod involved.

Requirements:

- Custom recovery like TWRP

- Rooted Phone (SuperSU / Magisk)

- File Manager with Root Access. I use Root Explorer

- OpenGApps (arm64,7.0) (package: stock/super/aroma) - This will enable some Nexus/Pixel exclusive features and install Google Apps that are preloaded on Nexus/Pixel Devices including apps that usually can't be installed as normal apk such as below:

- Google Phone

- Google Contacts

- Google Camera (Slow Motion isn't working)

- Google Now Card (swipe to right)

- Google Search Pill

- "OK Google" voice detection

Instructions:

* First thing to do is to flash OpenGApps via TWRP

Link: http://opengapps.org

* Install a navbar overlay from below thread to get Stock Android (AOSP) NavBar or Pixel NavBar. Install it as normal apk.

* Replace the stock Pixel Launcher (located at '/root/system/priv-app/NexusLauncherPrebuilt/NexusLauncherPrebuilt.apk') with this modded Launcher (link below). This launcher is basically the same as the stock Pixel Launcher with enabled features like round icons for app that supports it. More information on the original thread.

* Below are some apps i'm using that are supported:

- Google Photos

- Google Play Music

- Google Drive

- Google Calendar

- Google Calculator

- Google Keep

- Google News&Weather

- Google Playstore

- Google Drive

- Google Calendar

- Youtube

- Gmail

- XDA Labs

- XDA Feed

- Twitter

And now that you got all that is required to have a Pixel-like UI / Experience, it's time to make your ROM lightweight.

* Create a folder in your Internal Storage or SD Card named "system" and inside it, create folders "app" and "priv-app". This is to make sure that you can always revert back the changes that you'll make.

* Open your File Manager with root access and navigate to "root/system/app" or "root/system/priv-app"

This is where you can find all the installed apps in your system. In my case, what i do is "cut and paste" the whole folder to Internal Storage and then reboot to remove the bloat that i don't need.

I am currently on Renovate Ice ROM - r98 build (AQF7 FIRMWARE) and below is the list of what i have removed.

I am not getting any Force Closes / Crashes / Errors. Just make sure to reboot your device after cutting and pasting system apps to your Internal Storage.

When you realized that you needed something back, just copy and paste the whole folder to where you got them and set the correct permission.

For the folder, set the permission to "rwxr-xr-x".

For the apk inside, set the permission to "rw-r-r".

then reboot your device.

If you want to have an updated google apps as soon as it becomes available, you may download latest apks at apkmirror website then replace existing apk in the system, set the correct permission, and reboot. I've done it to almost all google apps without any issue.

I will try to update this thread to include all apps that can be removed based on stock firmware that's freshly installed.
