Unlike last year’s Zenfone 2 Laser, the Asus Zenfone 3 laser features a aluminium design instead of plastic one in the last year’s model. Back of the phone is soft and cool and they’ve reduced the size of the camera and added a fingerprint sensor too, that’s a plus. Power button has shifted to side of the phone just like most of the other phones.

Asus ZenFone 3 Laser measures in at just 7.9-millimeters thin and features a weight of 150-grams, allowing it to be very slim and lightweight. The phone is 150g but it feels really really light in hands, the weight distribution is awesome. My Leeco Le 2 weighs 153g and it was hard getting back to the Leeco Le 2, it just felt different and heavy than Zenfone 3 Laser.

On the back you see the Laser and next to Laser is the primary camera and next to camera its the flash. And right below the camera you can see the not so usually shaped fingerprint sensor

On the front you see the light sensor and then the earpiece and then the front facing camera. And at the bottom you will see capacitive buttons.


On the right you have the volume rockers and power button.

On the left side of the phone you will see the SIM card tray (closed)

At the bottom you will see the speaker and micro usb port and a microphone



On the Top you’ll see a microphone and a 3.5mm headphone jack



The display is good, nothing fancy here. Its Big, Bright and Clear. It is a 5.5″ 1080p panel which gets reasonably bright, is readable outdoors and in bright sunlight and viewing angles are good as well. Color reproduction is very nice. Its functional and touch response is really impressive judging by what we experienced with the Asus Zenfone 3 max.




Under the hood of the ZenFone 3 Laser is a Snapdragon 430 processor and 4GB of RAM. The 430 chipset being used here is of the octa-core nature and is clocked at 1.4GHz. This is a processor thats made explicitly for lower to mid-range smartphones, and that is very evident in the performance of the Laser.

Multi-tasking is very good as expected thanks to the 4GB of RAM. Here are some benchmarks:






User Interface

The Zenfone 3 Laser runs on Android 6.0.1 out of the box a top of Zen UI. Asus did add some useful tweaks here and there. The built-in launcher is extremely customizable, there’s a fairly robust theme engine to play around with, and there are tons of screen gestures to make use of if your heart so desires.



Asus didn’t go for the dual-camera trend with the ZenFone 3 Laser, and instead opted for a single 13MP sensor of the back along with an 8MP front-facing one. ZenFone 3 Laser is accompanied by a laser-assisted autofocus system. This is something that we usually don’t see on smartphones in this price bracket, and the snappy focus times that this addition allows for is greatly appreciated. Its really really fast when it comes to autofocus.

Unlike the last Asus phone we reviewed this phone comes with a manual mode ( It is expected to come with a manual mode)

The camera UI is still fairly minimal here. With a few quick settings on the left side, and your shutter buttons and other modes on the right side. Speaking of modes, you have Auto, Manual, HDR Pro, Beautification, Super Resolution, Children, Low Light, QR Code, Night, Depth of Field, Effect, Selfie, GIF Animation, Panorama, Miniature, Time Rewind, Smart Remove, All Smiles, Slow Motion and Time Lapse.



The Speaker on this phone is downward firing and is located at the bottom beside the micro-usb port. Most Smartphone Manufacturers do this and this is not necessarily a bad thing, but most people would prefer a front facing speaker because it makes much more sense.The ZenFone 3 Lasers speaker can be loud, but the audio quality isnt quite there. Sometimes it can sound a bit tinny, which isnt a good thing. Some of the highs arent great at all, but when it comes to the mids and lows, its pretty decent. But they are better than the Zenfone 3 Max’s speaker.


Finger Print Sensor

The fingerprint sensor on the ASUS ZenFone 3 Laser is located on the back of the device, below the camera. Much like the ZenFone 3 Deluxe, it is a rectangular sensor, which is a bit different, but it allows for what ASUS is calling 360-degree fingerprints. Well in our testing this was a bit difficult to get used to, the shape of the sensor is unusual.

With the fingerprint sensor here, there are a few extra features, or actually touch controls as ASUS calls them. Theres the ability to tap and hold the sensor to answer an incoming call, double tap the fingerprint sensor to launch the camera but only when the device is unlocked. And there is one where you can tap the sensor to take a photo from within the camera app. These features can be enabled and disabled individually by going to Settings—> Fingerprints



With 3000 mAh battery this phone is just as much similar as any another smartphone, I mean 3000 mAh is the new standard in big phones but this phone has the low-end Snapdragon 430 which should help in stretching the battery life a bit further than the competition and it does, you can expect a screen on time of roughly 4-5 hours and it is really impressive for such a big and bright Full HD display. And this phone runs on Android Marshmallow 6.0 which has the “doze” feature which helps in increasing the standby time when the phone is doing nothing.



If you are looking for a basic smartphone with a really great camera and build quality then go for it.
