I personally own a Lenovo a6000 plus
I have been using this phone for about a year and a half and there has been no complaints whatsoever
camera quality of the phone it should be improved but for the price target is good
the features in the phone are also good for the price
but I think some time is when you put the charger and use your mobile your mobile will heat up.
the phone has 16 GB ram and 2 GB ram it is enough for the phone
and another advantages the phone is so light that you can carry it anywhere you want.
You get the phone with the 4.4 KitKat but you can update to 5.1 lollipop
so in my opinion a good phone for its price
