Disabling apps only stops the app from running. Other apps can still call upon the disabled app to do certain tasks/routines/api calls. The disabled app will still continue to occupy storage and memory space.
https://android.stackexchange.com/q...ng-an-app-any-different-from-disabling-an-app

By doing adb uninstall, you are really deleting the app from your Walkman. No longer can any other app call up the uninstalled app. Also there will be a drop in storage and memory usage after doing adb uninstall.

Disabling app has the advantage of being easily reversible. But there’s a few(unwanted for music playback) system apps that cannot be disabled.

Adb uninstall allows for more deeper uninstall of system apps. But the risk exist for causing bootloop if you don’t know what you are doing and try to uninstall something that is required for the android to run.

My suggestion for non-experienced users is to use the disabling method first then once you are comfortable that disabling the app doesn’t cause issues then do adb uninstall later down the road.

For more gusty and experienced users, it is recommended to do google search on the package name to decide upon whether this app is safe to be uninstalled.

Most of the time for adb uninstall, provided that you do not do something really extreme(like trying to crack the encrypted boot loader), you can recover via DFU reset by pressing a certain key combination.

And in my experience, yes there is a slight UI performance difference between doing disabling vs aggressive adb uninstall. As for sound quality differences, I will say it’s kinda minimal but do note it’s about the sum of all improvements, a few minor improvements here and there do add up eventually.

A very optimised Walkman with a good quality low noise microSD card will sound much different from a unoptimised Walkman with budget consumer grade cards. The unoptimised Walkman will also have very slow UI response(jerking text scrolling and longer wait for page updates) as compared to a one that has gone through extensive uninstalling(liquid smooth text scrolling and almost instant page updates).

Yeah and I dont know if you guys follow cyber security developments but maybe a year or so ago someone at a cyber security conference as a proof of concept/highlight weaknesses made a USB C cable that had a virus built into that allowed root access to your phone.
That would be nice to be buying a usb dongle and have a rooted Android DAP without legworks 🤣

This new firmware is somehow using more internal storage space.

It used to be showing up as 14% in the previous firmware, now this new firmware is showing as 15% usage.

I don’t store any music on my internal storage nor do I have any other 3rd party streaming apps installed, not even YouTube.

@Whitigir

https://arxiv.org/pdf/2110.07124.pdf

I highly speculate that the methods described in this pdf is likely how Sony is using AI to analyse the music track to place sound objects like instruments and vocals in the specific spots of the headspace with very remarkable accuracy during playback of stereo music files. This can be done in real time processing but Sony likely have implemented a better power saving method by pre-analysing the music track and not having to do real time processing but using already determined positional metadata stored in the music player internal database to recreate the various sound positions during playback of that specific track.

Something that confounds me.

It seems the greater the fidelity, the greater the nostalgia. Even if I've never heard it at this level. This is a magic memory machine worth more than I paid :)
With this elevated level of sound quality we are experiencing with this M2 Walkman, I would be in the opinion that it greatly improves the appreciation of every music you listen to. It also gives even much more discovery of new musical details in the old music that you have listened to in the past.

What I find most impressive this time is how music sounds so much more cohesive as a whole. It’s very difficult to describe what I am hearing but I think it’s like a very well cooked dish where the ingredients, spices and aromas intermixes to form a whole body of flavour. The sound of this new Walkman firmware is just astonishingly beautiful and brilliantly crafted.

Just some food for thought:
https://www.chromausa.com/tech-review-why-do-ev-batteries-need-ripple-current-testing/

If electrical ripples from charging can affect the longevity of the lithium ion battery cells of an ev car, it also won’t be any far fetch to consider the idea that the charging ripples from usb-c charger can cause the same issues for the Walkman or any electronic device with lithium cells.

http://www.righto.com/2012/10/a-dozen-usb-chargers-in-lab-apple-is.html?m=1

So I think it is a good idea to research into getting a high quality clean power output(not related to wattage output) usb charger/powerbank for your walkman to extend the operational longevity of the battery.

Curious about the NW-A300 so just pre-ordered a blue one from Amazon.co.uk. See how bad they cripple the volume on EU/UK ones and easy to return.

Is it possible to sideload apps on the WM1AM2? Im trying to install Tidal,which isnt supported in my country,and im not able to open the .apk file on the Walkman. Any help appreciated.

Have you tried to update your firmware to international?

For those interested:
The Cable length of usb cable do matter for signal integrity:



So I suggest using shorter cables for transferring music to the Walkman, the Sony supplied usb a cable should do fine.
