Pls , I suggest to the people who have not bought Q7 yet but are keen on it, to avoid it. It has some hardware issue, My brand new phone a day old developed audio issue, If you plug in the headphone the audio would work other wise not. So the phone went completely on silent. I got it replaced from the shopkeeper after having a fight. He replaced it with the same model, was not ready to give any other brand. I am going to use it for 6 - 7 months but will never plug in "Headphones".
I don’t trust the phone much. Only thing attracted me to the phone was WIFI.
