Asus has started rolling out the Android 9 Pie update for the Zenfone 5z. The update is being rolled out over the air in batches, so not all users will get the update immediately. It's also not yet available for download on Asus' website to flash manually, so you will have to wait a bit longer for that. For now, you can just keep mashing the check update button repeatedly on your phone over the next several days till you get the update. As for changes, there are no specific details given besides what you can otherwise expect from Android 9 Pie itself. Thanks Erick, for sending...
