换的主板系统是1.08，为了弄到1.03我又卖了，重新买了个二手1.03的。 索尼不同版本固件声音还真有区别，这个确实讨厌

建议不要乱删，我可能删了安卓自带键盘，导致开机一直在圆点那无法开机成功。送去售后，还好在保修期，给换了个主板。。。

之前说到的ADB 软件删除系统软件操作不是人人愿意尝试，我看到有人推荐可以进调试模式删除和停用一些后台应用和服务，其中有不少是我们中国版固件天生就没有的服务，其他有需要的自己可以对应找一下，我关了这些服务后，系统占用运行内存从1.8g下降到了1.3g，好处就是运行速度明显快了，至于声音变化，我不发表意见，这因人而异，我现在贴出来分享下：


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:

Android Accessibility Suite
Android Opne Source Music Player
Bookmark Provider
Calculator

If any APPs start having issues running on your walkman, you can restore back the original App settings by doing this:
Settings > Apps & notifications > See All xx APPS > Tap on 3 dots at top right of screen > Reset app preferences

Privacy and other settings to check

Settings > Location > Off

Settings > Accounts > Automatically sync app data > slide to left

Settings > Network and Internet >Airplane mode > Slide to right

Settings > Network and Internet > Wi-Fi > Wi-Fi preferences > Notify for public networks > slide to left

Settings > Network and Internet > Wi-Fi >Scan settings > Wi-Fi scanning > slide to left

Settings > Connected devices > Connection preferences >Nearby Share > Off

Settings > System > Languages & input > On-screen keyboard > Gboard >Advanced > Share usage statistics > Slide to left

Settings > System > Languages & input > On-screen keyboard > Gboard >Advanced > Improve voice and typing for everyone > Slide to left

Settings > Google > Personalize using shared data > slide left for everything listed here

Settings > Accessibility > Remove animations > Slide to right

Settings > Google > tap on 3 dots at top right hand corner > Usage & diagnostic > Slide left

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

比价二手对全新？二手金二只要1.4左右，全新1.8

我是首发买的黑二，那时候木有什么二手好价格

昨天试了一下，满血个毛线，声音直白，比普通模式更难听。唯一的好处，恐怕就是省电了

一会试一下

zx2可以进去安全模式。但是声音从我的角度来说是劣化了的 味道少了也变冲了。不过还是感谢楼主 折腾哈哈哈

A306用你说的这个方法启动是正常的，没有安全模式

+1，看来306没办法

是吗？那好，是我们希望的，等等考虑一下，感谢

借楼出个黑二转大耳了

我也是日版。但是界面是中文的。不过升级固件必须要用梯子才能升级。我也想知道日本怎么可以刷国版固件。 ...

买来是1.03，现在升到1.07了

索六可以外接电源，只是可以选择你希望"电池供电输出"还是"电源供电输出"
两种声音有区别的，索尼骚操作

看来安卓砖果然是用脚做的, 暂且不论国外要用play的话需要框架, 就这些docs tv calendar没有一个是需要的吧, 居然都不删掉优化系统, 就搞了两个金属罩子自以为解决了噪声. 声音听起来比深度定制的一代浮躁很多太正常了.

明白了，索六万由于不能连接外接电源只能内部电池，所以我们一直没有下决心。我们有电磁炉，和索尼大Z和M7，接索尼播放器发现已经很好听了，

老板这钱分配的不好理解呀，有索六万但是没有黑一和金一，也没有金二，来个黑二对付，这钱花的。

zx2我很喜欢，后来zx2被我摔坏了，需要重新买个随身，金二那么重，怎么出门携带，既然携带不方便，在我定义里那么重的东西还是居家使用好。既然如此，作为居家设备，那么索六肯定是优于金二的，所以随身就是黑二，而且说实话，我没觉得金二比黑二多出的一万五值得，但是索六多出的那点我却觉得很值，这就是我的选择。
