[G3 Q&A, Help & Troubleshooting] Amb669:
Once you remove bloat it is completely removed forever, the only way to put it back on is using a backup of that app or doing a stock firmware flash, a factory reset WILL NOT restore any bloat you removed, but it's very easy to use titanium backup to backup and restore an app you remove.

If you have certain apps removed and do a factory reset while those said apps are missing it can make your phone act funny and break certain functions, I can make sure you 100% avoid this if you wait for me to update this list.

Here's a partial list of apps i removed (I removed alot more and will update this list shortly).

I will update the functions and purposes of most of these apps within the next couple hours, i would HIGHLY recommend to wait until i update this so you know exactly what you want to remove and what you want to keep. and i can explain a few very important things about removing certain apps within my list

App Updates ~~~~~~~~~~~ (This is LG's update function, Don't uninstall if you want to use Factory Reset function OR if you want to use LG's OTA firmware update OR if you want to update LG apps including calendar, calculator ect.)

Bell RDM ~~~~~~~~~~~~~ (Bell bloat, This app is somehow tied to Bells always running tracking software.)

Box ~~~~~~~~~~~~~~~~~ (Online cloud storage app, Don't uninstall this if you want to use the Box app for cloud storage.)

com.lge.lgdrm.permission ~~~ (com.lge.lgdrm.permission is used to watch "digitally owned" media, for example music/movie from itunes is owned by apple and is locked using DRM, Most likely your media isn't downloaded from such a source and almost certainly DOES NOT require DRM, If you remove this function make sure you also remove "DRM Service" or you may get a bootloop.)

com.lge.lgfota.permission ~~~ (com.lge.lgfota.permission is used to connect to LGs OTA service to download OTA firmware & updates for LG apps, Don't uninstall this if you plan on using "App updates" or downloading firmware via OTA)
