My Galaxy Note 2 can be upgraded to the highest version of Android 4.x only.
I like Notes as it comes with fine-head stylus and fits my palms just nice but I need to upgrade to higher versions as some of my company sites can't be accessed unless I upgrade to higher versions of Androids (for security reasons).
I need to make a few decisions on whether to get used Note 3, Note 4 or Note X based on a few questions below which I need experts to answer:
a) I heard newer model phones nowadays dont allow batteries to be changeable so does Note 3, 4 or 5 allow batteries to be taken out & replaced?
b) which models of Note allows upgrade of Android to the current latest available versions?
c) which of the Note 3, 4, 5 has a width that is the same or 1mm wider only (but not narrower) than Note 2
