June 17, 2019: Owners of the ZenFone 4 model ZE554KL now have a software update that installs Android 9 Pie as version 16.0620.1905.10. The update, which is available over the air, also installs a new Android security patch and stability improvements.
Asus pulled the original announcement about the update, only to release a second one, where they confirmed that the update is in the beta channel right now. However, you can easily download and manually install the update on your ZenFone 4, here’s how.
May 25, 2019: Asus has a new update for the ZenFone 4 Max and ZenFone 4 Selfie phones that install an AOSP-based version of Android 9 Pie beta. For the former, the update is targeting model ZC554KLand for the latter, the update is available for models ZB553KL and ZD553KL.
It’s worth noting that this version of Pie beta doesn’t include ZenUI, so if you are a fan, you might want to skip this update.
March 28, 2019: Asus is rolling out an update to the ZenFone 4 model ZE554KL with the latest Android security patch for March 2019. The update, which has version 15.0610.1903.26, also improves GMS to version 201812 r1, optimizes performances, and fixes bugs.
March 24, 2019: The ZenFone 4 Selfie and Selfie 4 Pro with model numbers ZD553KL and ZD552KL are receiving new software updates that install versions 15.0400.1903.508 and 71.50.395.80, respectively. The updates install new security patches, updates privacy setting and Google APPs.
The rollouts are available globally and since they are airborne, they will take some time before all units receive the download notification.
If you can figure your way around it, grab the download files in the respective tables below and install manually rather than wait for the OTA to arrive, probably later in the week.

Asus’ range of smartphones, like many other Android OEMs, isn’t that easy to keep track of. Besides the sheer number of devices the company has out there, it’s naming strategy is pretty much messed up like the Samsungs and Huawei’s of this world.
In August 2017, for instance, the company unveiled the ZenFone 4 series. Here, you’ll come across multiple ZenFone 4 devices, with some of them sharing the same name but with different specs (and model numbers). In this post, we give you a detailed coverage of the ZenFone 4 updates for the entire series, whose members include Asus ZenFone 4 Max (ZC554KL), ZenFone 4 Max (ZC520KL), ZenFone 4 Max Pro (ZC554KL), ZenFone 4 Max Plus (ZC554KL), ZenFone 4 (ZE554KL), ZenFone 4 Selfie (ZD553KL), ZenFone 4 Selfie Pro (ZD552KL), ZenFone 4 Selfie (ZB553KL), and ZenFone 4 Selfie Lite (ZB553KL).
Software update news for the ZenFone 4 Pro are captured here.

ZenFone 4 Android 9 Pie update
- Android 9 Pie expected in Q2/Q3 2019
Asus is quite good with software updates. The entire ZenFone 3 series got at least one major OS upgrade and another set has been upgraded to Android Oreo. This is exactly what we expect with respect to the ZenFone 4 handsets, where not all of them might receive Android Pie updates. But of course, this is just making an educated guess, but we hope Asus will make its Pie plans official sooner or later.
| Device | Current OS | Android 9 Pie update status |
| Asus Zenfone 4 ZE554KL | Android 9 Pie | Released on June 17, 2019 |
| Asus ZenFone 4 Max ZC520KL | Android 8.1 | Expected in Q3 2019 |
| Asus Zenfone 4 Max (Pro) ZC554KL | Android 8.1 | Expected in Q3 2019, beta available |
| Asus Zenfone 4 Selfie Pro ZD552KL | Android 7.0 | Not expected |
| Asus Zenfone 4 Selfie ZD553KL | Android 8.1 | Expected in Q3 2019, beta available |
| Asus ZenFone 4 Selfie Lite ZB553KL | Android 8.1 | Expected in Q3 2019, beta available |
