Why are you that much worried?
Smartron made sure that Android O will be rolled in jan 2018.
They started replying fast does not means that you starts asking tbe same android o question many times
Nearly 20 times Smartron team told that they will roll out android o in jan 2018
They are not in hurry
If they hurry, there are chances we get a buggy android o
So bro please calm down
