[Nexus 6P Q&A, Help & Troubleshooting] G5-User7080:
Ok, at first, probably noone can tell you about every app if its save to remove or not, but maybe i can give you some additional information since i removed a few on my phone but keep in mind that i own the Moto G5, not the Nexus.

The best advice i can give you: If you want to know wether you can remove an app or not, google its purpose and/or try out what happends when you remove it, if your phone gets a bootloop or some functions or apps arent working anymore you shouldnt have removed that app. However, that will take a fair amount of time, because in most cases you only see the difference after a reboot. Of course it would be good having a twrp backup, or just reflash system everytime after you failed.

The list of apps i tell you now which should be safe to remove applies to my phone with the apps i use, it doesnt necessarily mean, the result is the same, but to be fair, the result is probably more depending on what apps you use and not the phone model. F.e. i noticed i shouldnt remove google chrome, because somehow the notifications from one app didnt work proberly, although i dont use chrome as browser.

I just copy past the list from dladz and edit it:

So just google things but it may be useful to google the package names and not the app names, since they differ from model to version and language.

What i did:

writing down all suspicious or unnecessary sounding things (i had an app calles "bug2go" wtf?), google them, maybe with package names and once you know what they do or should do and you decide you dont want or need them, delete them. Once done, reboot, check if your phone and your apps are working, browser, music, notifications etc, if not,.... restore backup and try again but this time only the first half,... and so on until you found the ones you shouldnt delete.

Good luck!

btw. if anyone of you flashed a custom rom, would you mind checking my question about the correct procedure, i dont need perfect answers, but a little help what you guys think or did would be great!
