Sony xperia z1 is not a great phone at this time.the screen LCD type and viewing angels not good, it does not support fringerprint scanner and also it does not support fast charging option, the camera quality is not too good as compare other phones.and phone getting too much hot wile recording video stooting and capture photos and price may be too high at this this around 23K.In this price other good phones are available in market, and it confirm it does not get Android OS M update, but in sony xperia z2 will get that.The audio output is clear but speaker is not too much loud.!
