I am not satisfied of sony xperia z1 because this mobile camera was very poor, not full clearity and pixel was not satisfied. Normally non removable battery phones slim but sony’s phone non removable battery but for thick phones. Sony xperia z1 in 20.7 mp camera compair to samsung galaxy’s phone 13mp camera but samsung was very best and fastest. Sony xperia z1 was waterproof phone but in this phone pour in water so some time speakers was not perfectlly sound minimum 15 minutes than normal function.
