The ZenFone 4 Max Plus sports a 5.5-inch (720x1280 resolution) LCD display. The brightness distribution is decent enough for a uniform color representation. The rear cover is made of aluminum. The smartphone feels good in hand, and it is fairly soft and ergonomic due to its rounded edges. One of the ZenFone 4 Max Plus defining features is its triple slot for two SIM cards and one MicroSD (up to 256 GB card) at the same time. Asus’s own in-house user interface - ZenUI 4 - is preloaded on the 4 Max Plus, and it comes with some useful apps for extra security or smartphone maintenance as well as an app called “Selfie Master”. A simple mode and kid’s mode are also available, and they allow further customizations for one’s individual requirements and needs. Handling of the phone is very smooth overall. The touchscreen is very sensitive up to its edges and corners. A fingerprint reader capable of waking the phone from standby mode is located right underneath the display, and responded to the fingers quickly and reliably. Once unlocked, the button the reader is integrated into served as home button, enframed on either side by capacitive back and app switcher buttons. The home button as well as the right capacitive button can be remapped in the settings. For camera, the phone features a dual-lens camera with a wide-angle lens at the back and a single-lens camera with LED flash at the front. The main camera’s resolution of 13 MP is accompanied by the wide-angle camera’s 5 MP sensor. Zenfone 4 Max Plus has a huge 5000mAh cell capacity which could last for a day or two of moderate usage. Thanks to Quick Charge, charging the battery from near empty to full takes just two hours.
