[LG K7 Questions & Answers] ObliviousEnigma:
Hello, notphongnguyen.

I'm currently running a: LG K7 MS330 as well (latest security patch updates and everything that was updated from stock).

I'm systematically running through eliminating programs / services (daemons) on: User / System level.

When I'm done (possibly by tomorrow): I'll post my findings in the format of APK (application package or "installer") names.

This will allow you to modify your system in various ways (modified ROM file or directly on the phone itself; Just to name 2).

I understand you only have 1 post. I am hoping you subscribed to your thread (e-mail).

This post is also being created to hopefully address future users who find this thread.

Thank you for your patience.

EDIT

Sorry for the delay (in the event you received an e-mail and were patiently waiting for an update)!

It took quite a while to run through all 158 packages that you can successfully disable

without

causing system-instability or an inoperable system.

I did not document 100% every aspect of every package, but I do believe I found and documented the majority of the alterations caused.

adb shell su -C am kill-all
adb shell su -C am force-stop com.hy.system.fontserver
<insert remaining disabled processes>
adb shell su -C am kill-all

Hopefully these findings will result in some helpful information or general tweaking of someone's ROM or phone! You can definitely cut out A LOT of these packages without altering the system very much! I am sure we can

all agree

that no one needs the "EMail" or "Music" or "Voice Recorder" or etc app with a legitimate 'stock firmware ROM,' as the person will likely remove them upon immediate installation (flashing) of the OS.

You're welcome.

EDIT: FINAL NOTE AND REMINDER

If you end up disabling the wrong package (EG: "system instability" or "system inoperable"): Do not worry! Even when you're stuck on the bootanimation ('screen is frozen'): You can still issue ADB commands to enable/disable packages.

Example: You disable com.android.settings or com.lge.provider.systemui

In either event: You can repair this with adb on the fly.

adb shell su -C pm enable com.lge.provider.systemui

Happy tweaking! :cool:
