i don't know exactly which ones. i know none of the google apps can be. i know i removed a few others for my wife, but had to merely disable a few also. overall, i recall thinking that there really wasn't that much bloatware compared to some of their past phones.
All the pre-installed apps can be disabled besides Verizon HotSpot, MyVerizon, and Voicemail. However, only a few apps can be fully uninstalled.
I'm not a fan of many of the preinstalled apps so I love the fact that 95% of them can be disabled.
