Sony recently halted the Android Nougat update for the Xperia Z5, Xperia Z4 Tablet and Xperia Z3+ smartphones due to some issues reported by users. The company now released an update on the firmware, saying that it is "still working on the inconsistencies" and that the firmware rollout will recommence as soon as possible.
Some users were complaining about unusual battery drain after upgrading to Android 7.0 Nougat, and some about the audio issues. Since Sony said the company's "priority is user experience," hopefully all the bugs will be fixed.
We’re still working on the inconsistencies in Nougat for Z5, Z3+ and Z4 Tablet - priority is user experience. Will re-commence rollout ASAP.— Sony Xperia News (@SonyMobileNews) January 23, 2017
