used the Package Disabler... and it actually slowed down all my devices after a couple of days. All of them incuding the new V30.
I had to reboot the devices every day: PowerAMP stopped working due to RAM when I started browsing the web etc....
Now I simply use my V30 as it is and it's superb... no issue with RAM.
So my advice: if you dont have warranty just ROM your phone, if you do have warranty -as my new V30 - dont use Package Disabler Pro..... it not just doesnt work, but makes your phone buggy, lower, run out of RAM even thoough you have less funcion than before..
- what you want to disable like Google Movies, Play, or GoogleMusic - you will be able to do that from the Settings.
Yes, LG really optimized the firmware to not have lags. I know people may not want some apps/services on their phones -- but sometimes it's just better to ignore or hide them, if they care about how the phone runs. So much is interconnected.
It's not like a few years ago when each system service or system app in stock firmware was totally separate components.
