everything wants to know everything about you and your location.. it's all creepy, with time stamps and pattern recognition they can pretty much know your routine and what you were doing..
I finally got around to rooting and deleting a lot useless apps on my old Galaxy S5... made for a world of difference. Also, got around to installing Hataroid (Atari ST emulator) which is fun for when I'm waiting for someone in a car or whatever. But ya... some apps are big ole memory hogs.
