Samsung Z4 just launched few month ago best budget smartphone, Samsung z4 is not a good smartphone but its good for low budget 4G enable smartphone. Sound quality, style & design was good and unique. RAM 1GB and processor are not good for gaming. Camera is not bad to compare this budget in other 4G smartphone, I am not suggested to buy this phone, but my opinion for Samsung Z4 is good and satisfied look and style low budget Smartphone in market.
