Asus ZenFone 3 ZE552KL Review: Software

Perhaps the achilles heel of the Zenfone 3, the phone still runs a very bloated version of Android 6.0 dubbed as Zen UI 3.0. Right from the lockscreen to the pre-installed apps, there have been customizations all the way through. In a recent conversation with Peter Chang of Asus, we were told that users quite enjoyed this implementation, it’s certainly a little hard to believe though.

The lockscreen shows the time, date, weather and notifications. You can also have three shortcuts placed here while swiping up from the corner reveals the camera module. Drop into the homescreen and you get access to the all the apps and widgets placed here. Asus ZenFone 3 ZE552KL Review. The homescreen can be modified via additional icon packs, themes and more. Additionally, unlike recent devices, you can tap a shortcut on the homescreen to enter the second level app drawer.

Asus has taken upon itself the task of providing users an app for almost every use case possible. From file managers to task lists to even a laser ruler! Removing Google’s apps from the equation, we counted a whopping 26 pre-installed apps. For what it’s worth, a couple of these can be uninstalled. You can disable most of the others but they still do end up occupying space on the phone.

There’s also a full range of gestures and shortcuts built into the device that stretch from double tapping the homescreen to enter one hand mode, long pressing the app switch button to take a screenshot as well as double tapping the fingerprint reader to open up the camera. There’s more strewn all around and they do add to the ease of use. As we said earlier, this is a very heavily customized version of Android but the additions are quite useful for the most part.

You can use this app to capture your screen while playing and also live stream to YouTube or Twitch. A very cool feature here is that you can overlay a live video from the front facing camera over the stream from your screen while broadcasting to a social platform.

From an interface perspective, the software on the Zenfone 3 is quite inoffensive and is generally about as good as the competition while offering a couple of additional options. What we didn’t appreciate was the copious amount of bloat pre-installed on the device, something that the average user wouldn’t be able to get rid off.

Asus ZenFone 3 ZE552KL Review: Design, build and controls

Asus ZenFone 3 combines glass and metal into one, creating a body that is sculpted with precision and attention to the smallest details.
