I'm still running 4.4.4 kitkat, system ver 21.44.12 and phone works great. Short question is can I go from 4.4.4 to 6.0 without going thru 5.1? I have read too many negatives about 5 and want to wait for 6. The updates have downloaded to the phone but I have successfully denied the install prompt EVERY DAY to keep kitkat. If i do a wipe partition the update is removed but quickly re-downloads when the phone boots up again, and back to the daily notif to install. I understand if this is still an unknown.
