Yeah I am using this phone since last 6 months and is not satisfied with its functions. ALthough the hardware is good enough as it comes with 2gb ram and 16MP rear cam which shoots quite well when the flash is turned off.
I am quite suspicious about 1.5 octa-core processor which iguess is not that much as the devices lags a lot and has shows many glitches in the network connectivity.
The device looks good but bulged out camera in not that much pleasing as it is more prone to have scratches.
Also there is no Official Android upsate for this device which is still running in KitKAt.
