Privacy? I am astonished that you're seriously asking this.
Is this the point about unlocking the bootloader being risky, or did you just pour the Google/Samsung advertisement ethos down your throat?
I guess that's a fair reason. I hadn't really considered that because I don't personally care too much
I'm interested; are you saying you don't care about privacy from your android device?
I don't care to enhance it any further from the default experience, especially with the downsides
Downsides?
Can be quite a bit buggier than stock, can be difficult or impossible to use some apps. You can lose some stock features sometimes. You can spend a lot of time debugging issues.
What services does it have that are listening on external interfaces?
It's not necessarily about listening.
Many/most apps try to connect to Facebook, for example. Part of the ghost profile issue.
Or a handful of other data gathering services.
Blocking those are useful for both privacy reasons and battery life.
Those apps like to run in the background at al times, registering for every single receiver the phone has (apps like Solitaire, for example). If I didn't block receivers many apps would run all the time, even apps I use once a month.
It's MY phone... End
That's the point. I don't know.
