I dunno, I'd still be using my Note 2 if the power button hadn't died. Note 5 is still running fine. I've run out of reasons to care to root, but easiest way to fix those suspicions or realities is to install an independent version.
note 2 is still my favorite phone to date. i traded my note 5 for an iphone 8, but not entirely by choice; it was inevitable that work would force me to, eventually. sigh. to be honest, it feels exactly like the iphone 6 loaner i was using while waiting on a new phone, but a tad quicker.
my personal phone is a nexus 6, still running strong, though i hardly use it.
