I plan on leaving 4.2.2 alone. My phone is perfect. Lag free. Great battery. And adobe flash works great. I use xposed, so it's just like being on a custom rom in the end. Yes, boot loader is unlocked and I'm rooted.
I see no reason to change it at all..... Aside from being a flashaholic that just can't resist the latest version and custom roms.
Not me.... Unless something amazing comes along in an updated version..... I'm leaving this thing right where it is.
