Yo. I bought this phone on 19 jan with vr bundle and this is awesome phone I love this a lot.
I have been using this device as my daily driver and even im posting this review from k4 note itself.
3 gb ram makes it powerfull but processor can be good in terms of haivy gaming on this device .Camara is also good and producing good quality images.Please buy this device with vr bundle and experiance the vr technology .im loving this phone.Overall a good smartphone in this price range.
