The smartphone specifications , with 3GB RAM, 32GB storage space now being common, even in devices that cost just Rs 10,000 or under. But their smartphone cameras are still one segment where manufacturers can hope to stand out from the smartphone user crowd. In Oppo’s case, oppo's has decided to focus on the front camera, and give this selfie-obsessed generation a reason to rejoice.

Asus ZenFone 3 (ZE552KL) packs a 64-bit octa-core Qualcomm Snapdragon 625 processor clocked at 2GHz with integrated Adreno 506 graphics, as well as 4GB of LPDDR3 RAM. There is 64GB of inbuilt storage and support for microSD cards of up to 2TB for expansion. Asus is also offering 100GB of free cloud storage space for two years, in collaboration with Google. The hybrid SIM slot supports one Nano-SIM and one Micro-SIM or microSD card. Asus notes that both SIM cards support 3G and 4G networks but only one SIM card can connect to 3G/4G networks at a time.

The phone is powered by a non-removable 3000mAh battery, which supports fast charging. There's a 16-megapixel rear camera with f/2.0 aperture, 6P Largan lens, and dual-LED real tone flash. It used sony's IMX298 camera sensor. There is also an 8-megapixel front-facing camera with f/2.0 aperture. The rear camera uses Asus' new TriTech auto-focus technology which Asus dedscribes as a combination of laser, phase detection and continuous auto-focus modes.

One of the biggest highlights of the ZenFone 3 has to be the support for 4K videos. The camera can also record videos at full-HD and HD resolutions. It has octa-core Snapdragon 625 processor.

Overall, the ZenFone 3 is an excellent mid-range, mid-2016 smartphone. The low points for me are some aspects of the design, the audio quality, and the software bloat. The high points are basically everything else: it's fast and smooth, the screen is bright (but could be better in direct sun), the camera shoots 4K video, and some of the ZenUI apps are actually useful.
This is a slightly cheaper Smartphone to the Other competetor available in smartphone market, As an overall smartphone the Asus Zenfone 3(ZE552KL) ticks all the right boxes, then go with the oppo's F1s, but remember you are shelling out Rs 21,299 for these. Otherwise there are several options available in the market where you can spend less to get more on the performance like Moto G4 Plus, Samsung Galaxy J7, etc.
