Sony在英國的子公司在推特正式宣佈Xperia Z4 Tablet、Xperia Z3+、Xperia Z5預於三月七日開始更新Android 6.0：
@FalseNugget it's set to roll out from March 7th for Xperia Z5 series, Z4 Tablet and Z3+ – we will share confirmed timings when its ready
— Sony Xperia GB (@sonyxperiagb) February 15, 2016
值得注意是，這則推文這句「We will share confirmed timings when its ready」，意是是說確切的日子底定後會再更新，依據過去Sony升級更新的日期常有不準的記錄來看，小編覺得三月七日只是一個可能的日期。
