The ZenFone 3 sports 2.5D curved Corning Gorilla Glass on the front and rear held by a metal frame. The polished metal chamfers on the front and rear and the absence of antenna lines at the back are nice touches. For display, the device has a 5.2-inch Full-HD IPS (1080x1920) display. The display is incredibly sharp and offers crisp visuals and good clarity. It’s vibrant, offers rich colors, and it is a treat to watch high-res videos or play games on it. The touch response too is smooth and fluid. The ZenFone 3 features high brightness level of 600nits and therefore sunlight legibility is pretty good. The viewing angles are great too, and the display supports touch recognition through gloves. In addition, you can control the display settings with the built-in Splendid app that allows you to choose between Balance, Bluelight Filter, Vivid, and Customized color modes. The Bluelight Filter mode cuts out the blue light so that the display is easier on the eyes.

The ZenFone 3 is powered by Snapdragon 625 together with a 4GB RAM. This allows the device to perform like a breeze with no apparent lags in multitasking or navigating across the UI. This device sports a hybrid SIM slot that can take in a Nano SIM along with a Micro SIM or a microSD card. Camera wise, Zenfone 3 has a 16MP rear camera with a f/2.0 aperture and packs in 6P Largan lens, and focuses on the subject really quick. According to ASUS, the TriTech auto-focus technology on the ZenFone 3 combines laser, phase detection, and continuous autofocus allowing the device to focus in just 0.03 seconds in all conditions. There’s also Optical Image Stabilization (OIS) as well as Electronic Image Stabilization (EIS) which are quite handy while shooting videos and still shots in difficult light conditions. The colors are vibrant, and the photos include a great amount of detail and accuracy. The Zenfone 3 also has an 8MP front camera which take sharp and detailed selfies, even in low light conditions or when indoors. The camera app on the ZenFone 3 packs in a lot of options and camera modes to choose from. There’s also a manual mode for tinkering with the DSLR-like camera settings as well as a low light mode that enhances light sensitivity for clearer and brighter low-light shots. For battery, the phone is packed with 2600mAh cell capacity which could last the phone a day with light to moderate usage.
