So normally I use a linux laptop but the screen of my old phone broke I finally got an android device (samsung galaxy note). I'm quite pleased so far but have a few general questions: 1. I've read about rooting the phone, is that process reversible? 2. If the phone is rooted can I choose to use it with or without root privileges or if it's rooted once I can only use it with root priviliges? 3. There are loads of preinstalled samsung applications which I don't need (allshare, buddies now, social hub, etc, etc), can I delete those somehow (the normal software removal procedure doesn't work)? 4. Is there something like a shell for viewing the full file system? 5. Already installed connectbot, pretty cool! (okay, this is not a question ) 6. sl4a and python both work (not a quetsion either ) 7. If I want to stay anonymous to some extent and want to disconnect my google account from the phone so that it doesn't download anything from gmail, calendar, etc, etc, and doesn't do any syncing what services will be lost as a consequence? 8. Is there a simple one-click type of way to disable all network connections? 9. How do I control what processes/services are started up at boot time? Well, I guess that's it, basically any info that will help me feel at home on the device the same way I feel at home on my linux laptop would be greatly appreciated!
