Asus Zenfone 4 Selfie was launched last year. Since then we’ve not got major updates for both the ZD553KL and the ZB553KL variants of this smartphone. Well, now the official Android 8.1 Oreo update is rolling out for both devices. The company announced the update in their official forums. And, it updates your Zenfone to the new software version15.0400.1809.405. Also, the ZenUI will get an update to ZenUI 5.0.
So, in case you’re a Zenfone 4 Selfie owner than the update may take some to come to your smartphone. And, it may even take more than a month for the update to arrive in these smartphones all over the world.
Anyways, if you haven’t received the notification yet, go to Settings > About > System update to manually force a check.
