[General Questions and Answers] Lusty Rugnuts:
Download My Android Tools to your computer, save it in c:\test

It's got a really long name, so rename the file to just 'AndroidTools.apk'.

In an Administrator-privilege command prompt, type:

adb push c:\AndroidTools.apk /sdcard/AndroidTools.apk

The AndroidTools.apk now sits on your phone at /sdcard.

Open Total Commander and navigate to /sdcard. Long-press the AndroidTools.apk file, and select 'Play (foreground)'.

This will open the Package Manager to install the AndroidTools.apk file on your phone.

After the install, you can delete /sdcard/AndroidTools.apk.

Open My Android Tools and peruse through what it has to offer... it can disable pretty much any service or app... much more to come on this. Keep in mind that this is the type of app that'll let you completely bork your phone... so have a recent backup ready.

========================

Google Play Services didn't like some of the settings I'd changed, so the first time I switched to the "Google Enabled" firewall profile, it downloaded new settings for Google Play Store, but for the most part, the settings stuck.

In Settings > Accounts > Google, you'll usually find all your sync accounts... I've only got one left (Play Games Cloud Save) and sync for it is off. I'll eventually figure out how to get rid of it, as well.

In Settings > Google, I've got a completely blank window:

Screencaps taken courtesy of ADB:

adb shell screencap -p /sdcard/screencap.png

adb pull /sdcard/screencap.png c:\test

adb shell rm /sdcard/screencap.png

So Google's nearly banished from this phone, yet Play Store still works.

The phone feels snappier, and at idle, CPU utilization is now at a new low:

And the OS is going easy on the memory. We can get the free memory by adding MemFree and SwapFree: 1,985,832 kB free, or 940,064 kB in use (32.13%).

{UPDATE}

Strangely, the Play Store still worked, and I got app updates from it, but the Settings menu says the device is no longer certified... but it also says uncertified devices won't receive updates. Weird.

I rolled back to a backup I'd taken just before starting these alterations, and now Play Store says the device is certified again. I'll redo the alterations, but I'll do more research to be sure I'm just disabling those components which reduce privacy and performance.

Did I mention (several times) that you need backups if you're going to experiment with your phone?
