Asus ZenFone 3 Android Nougat update "on hold", should be re-released soon
At the moment, there's no word on when Asus will solve the issues and re-release the Nougat update, but we hope it's going to happen soon. Meanwhile, Asus advises ZenFone 3 users to activate the auto update option via the phone's Settings menu and "kindly wait."
In case you're wondering, all Asus ZenFone 3 models released last year should be updated to Android 7 Nougat. Obviously, the ZenFone 3 Zoom (announced earlier this month) will also get Nougat at some point. We'll let you know when Asus has new info to share on this.
