First of all these is the worst job by samsung.
This product is not worth even ten dollar.
Its processor is not up to mark and also because of heavy touchwiz ui it sucks.
It just freezes and unfortunately I have to restart it.
Camera is as good as its absence.
Image quality is yellowish.
There is no great detail or detail yhat should be.
There are only 1-3sensors.
And till this date Samsung had just neglected this device.
As it is samsung device it will not recrive any over the air updates so just root and install cyanogenmod to boost its performance and its utility
