Guide last updated: Nov 2022
General Disclaimers:
This guide is completely optional, you don't have to perform this optimization if you don't feel comfortable with adjusting with inner workings of android OS
There is no guarantee that this guide will not cause unexpected issues with operation of your Walkman. Try at your own risk.
Please note that this guide was made in Apr 2022, the best efforts on my end was made to ensure that this tweaks and optimisation worked back then with firmware 1.01.
if you are reading this guide on a much future date, there are likely new changes in firmware or Google’s app dependencies that might result in unsuccessful debloating or cause certain app to malfunction. This will require more trial and error on your end to ink out the issue. Please do read to the end of the thread to check upon if anyone else has give new information that will help to resolve any new issues with debloating of newer firmware.
Please feel free to add anything else missing from this guide and also post any new issues and troubleshooted resolutions you found with the guide to allow others to benefit from information.
Enabling Fresh Out of box Settings:
Settings >Hi-Res Streaming >Slide to right
Settings > Battery > Battery Percentage > Slide to right
Settings > Battery > Battery Care > Use Battery Care > Slide to right
Gain Access to Android Developer Options:
Settings > About Device > scroll to bottom of page, then Tap Ten times on Build Number
Once this is done, go to:
Settings > System > Advanced > Developer Options
Windows animation scale > Animation Off
Transition animation scale > Animation Off
Animator duration scale > Animation Off
Doing the above will disable unnecessary Android system fade animation that slows down App switching(along with unnecessary graphics processing power usage). You will notice more instantaneous app switching.
Apps that are deem safe(by me) to disable in the context of using your Walkman for streaming apps and music playback.
Settings > Apps & notifications > See All xx APPS > Tap on 3 dots at top right of screen > Show System >
Apps to disable(tap on each app and tap on disable):
Please note that you can also uninstall apps which is more effective than just disabling apps but to uninstall apps you need to enable usb debugging mode and use a software on your computer to uninstall. Please read further down this thread for more info:

You can also consider changing the Google keyboard app to a lower memory footprint app like simple keyboard or Microsoft swift keyboard. Please note that only Google keyboard will work in safe mode so do not adb uninstall the Gboard app but to disable it instead for in case of emergency situatons where you need to go safe mode and require software keyboard input.
For those using Google playstore account, you may want to change these to protect your privacy better:
Settings > Privacy > Advanced > Ads > enable debug logs for ads (turn off)
Settings > Google > Personalize using share data > other on-device sources > turn off both device contacts and external media
