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 risk.
Please feel free to add anything else missing from this guide

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:

Thanks for sharing. I will try these things when my 1Z arrival.

Btw, I tried but can't remove the Search bar on the main screen In theory, you supposed to touch and hold the screen and option to remove Search Bar should appear at the top (common to Sony Xperia phones). But it is not happening here.

It's not removable. Also you cannot customize wallpaper on this walkman.
What I have done, is to move all of my app shortcuts to a new 3rd page. The first page with the non-removable search bar, I placed a clock widget below it. My default home page is on page 2 with the walkman music app.

It is possible to change wallpaper on the Walkman. You need to install nova launcher from app store. Change wallpaper from there. You can still choose to use back the default launcher afterwards.

Here's something worth trying for those who want even better battery life:

for those who don't wish to use command line to uninstall bloatware, can give this GUI app a try

Very useful app/tools! And easy to use

@Sonywalkmanuser srr, but any ideas which service can give the color back to normal? I disable some unuse service yesterday, but dont know which one make this problem.

@Sonywalkmanuser srr, but any ideas which service can give the color back to normal? I disable some unuse service yesterday, but dont know which one make this problem.

Unfortunately I don’t own the WM1ZM2. I don’t have the gold volume control UI for my WM1AM2.

Did you disable anything outside of what I have listed?

I think your best course of action is to roll back what you have disabled. It should solve the issue.

 

[kenjamin0523]

Yeah, I disabled some service relating to phone and wallpaper, but I dont think it causes the problems here. I will check out tmr. Thanks anyway.
