LG K40

Design and Display

Unlike the LG Q60, this phone comes with a design that sports bezels on both ends. At the top bezel, the camera and LED flash are the major inhabitants alongside the earpiece and a few sensors.

While the Google Assistant key takes the right side of the device, the other physical keys are located at the left side. An allocated button to wake the AI brings reminiscence of the Samsung Bixby button.

A 5.7-inch IPS touchscreen churns out the multimedia on the LG K40. Its fineness is dictated by 720 x 1440 pixels resolution and 269PPI pixel density. Not to forget, the fingerprint sensor at the back guarantees biometric security on the phone.

Battery and Camera

A decent 3,000mAh battery provides the juice to run the smartphone for at least half a day. To balance the slight deficiency, the usage of a power bank will be instrumental.

To snap cute pictures, the 16MP camera sensor links up with an f/2.0 aperture. In poorly lit environs, a LED flash adds illumination effects to the imagery. On the other hand, selfies are dished out by an 8MP front-facing camera.

Hardware and Software

Speaking of its hardware, the MediaTek Helio P22 is well oriented to run lag-free actions on the smartphone. Its 12nm FinFET process coupled with the 2GB RAM makes efficiency more reliable. Another iteration sporting 3GB gives more fluid multitasking.

LG stuck with the Android 8.1 Oreo OS rather than the latest Android Pie software. Away from that, a spacious 32GB ROM is available for storage. With the help of a MicroSD card, the storage can even be expanded to 512GB.

LG K40 Pricing and Availability

The smartphone sells for about 58, 000 Naira depending on the location and deal.
