Since some Zenfone smartphones have different hardware configurations depending on regions, the model numbers eligible for the update are Asus Zenfone 3 Laser (ZC551KL), Asus Zenfone 3 Zoom (ZE553KL), and Asus Zenfone 3 Deluxe (ZS550KL). Up till now Zenfone 3, Zenfone 3 Max, and Zenfone 4 Pro have been upgraded to the new operating system.
In the ASUS ZenTalk forums on Monday, an ASUS community member said that the update for the ZenFone 3 had begun rolling out. It brings the phone’s firmware up to version 15.0410.1712.31, and includes changes like a new swipe gesture, “more friendly […] UI”, and the deletion of applications like PhotoCollage, Minimove, and Do it Later.
ASUS says that because the update server pushes firmware out to different device serial numbers in batches, it might take several days for your phone to receive it. If you’re feeling impatient, a community support member suggested heading to the ZenFone Settings > System menu and tapping the System updates button, which might kickstart the update.
