Asus Zenfone 4 Expert Review Summary
Expert Rating:
![Ketaki Bhojnagarwala]()
Verdict
The Zenfone 4 is by no means the perfect device, but when you compare it to the competition in the same price range, its perks become obvious. Unlike most other affordable smartphones, ASUS has been generous with the internal storage on the Zenfone 4, leaving plenty of space to install apps and games. The smartphone also packs in a reliable chipset, a healthy amount of RAM, front and rear cameras, and of course a gorgeous interface courtesy ZenUI. There are areas where the device lacks of course
Pros
- Compact build that`s ideal for one-handed use
- Responsive display
- Dependable performance
- Ample internal storage
- ZenUI offers several useful features
Cons
- No ambient light sensor
- Average display resolution
- Poor battery
- Android hardware keys aren`t backlit
Compact build suited to one-handed use
+
The Zenfone 4 is the smallest handset in the Zenfone line-up. Its 4-inch display makes for a compact size that’s ideal for one-handed use, but might feel slightly cramped for those with bigger digits. Like the Moto E, the Zenfone 4 features a soft-touch back panel, which unfortunately picks up smudges like nobody’s business. Unlike the Moto E though, it’s very lightweight, tipping the scales at just 115g. This also doesn’t make it feel as reassuringly solid.

Scores for responsiveness, but not resolution
+
While the Zenfone 5 offers a 720p display, on the Zenfone 4 you get a meagre 840 x 480 pixels resolution. Because of the smaller 4-inch screen size, the pixel density is an acceptable 233ppi, but the display isn’t as sharp as we’d like. Text on webpages appears jagged when zoomed in, and photos and videos don’t stand out either. The display is also highly reflective, so it isn’t ideal for watching videos. Unfortunately, the Zenfone 4 doesn’t feature an ambient light sensor, so you’ll need to adjust brightness manually. ASUS has provided a sliding meter to adjust brightness via the notification bar, but we still found ourselves having to tweak it frequently.

PixelMaster of modes
+
Given its price tag, we didn’t expect much from the Zenfone’s camera, but it’s a definite improvement over the Moto E’s lone 5MP fixed-focus shooter. While the Zenfone 4 also offers a 5-megapixel snapper at the back, it does have autofocus. ASUS has also been generous enough to throw in a front camera with VGA resolution, which isn’t ideal for selfies but should suffice for Skype calls. The camera is also endowed with ASUS’ PixelMaster tech to improve image quality.

ASUS has got it right with the ZenUI
+
The Zenfone 4 runs Android 4.3 Jelly Bean, with the custom ASUS ZenUI on top. ASUS has promised an update to KitKat, but it hasn’t arrived as yet. Like we noted in our Zenfone 5 review, ZenUI is one of the nicest skins we’ve seen on Android. Consisting of colourful icons and several useful apps and widgets, it offers several additions to stock Android, but doesn't cause the phone to become sluggish.

Dependable daily driver, but a fuel guzzler
+
The Zenfone 4 is equipped with a dual-core Intel Atom Z2520 processor, clocked at 1.2GHz, and paired with 1GB of RAM and PowerVR SGX544MP2 graphics. The Zenfone 4 didn’t freeze during our two-week testing period and was fine for daily use, but we did notice minor lags when opening apps, especially straight after waking the device. Performance was smooth otherwise, with none of the sluggish behavior we found on the Lava Iris X1 (review).
