Product Description

The LG K40 is a great phone for those looking for a budget-friendly option that’s still excellent. It launched in March 2019, following the LG K30 2018 model. This device offers a lot of useful and satisfactory features, including decent battery life, a great camera, and numerous connectivity options.

LG K40 Features

The LG K40 has a full metal unibody design, a glossy finish, and a subtly accented color. It also has a beautiful 5.7” HD+ FullVision display, with an impressive resolution of 1440 x 720 pixels. The screen is made from high-quality materials, allowing you to see every photo and video in great detail.

The great thing about all LG phones is that they save on unnecessary apps and bloatware. You’ll just get standard Google and in-house apps. The rear camera has 8 MP, and the front camera has 5 MP, which is surprisingly good for a midrange phone like the LG K40.

LG K40 Specifications

Another great feature of the LG K40 is that it’s lightweight and compact, weighing in at just 145 grams/ 5.11 ounces. Since it has rounded corners, the phone sits in your hands comfortably.

It runs on the Android 8.1 Oreo operating system and has a 1.8GHz Octa-Core Qualcomm Snapdragon™ SDM450 processor. The K40 has 2GB of RAM and 32GB of internal storage, enough for you to install all your favorite apps and games. However, you can’t expand the storage with a microSD card.

Even though this device comes with a micro-USB port, it doesn’t have a Type-C port. The 3,000 mAh non-removable battery can last for 12 hours while offering up to 10 days and 12 hours of standby time.

Modern Design

What makes this phone desirable in the first place is its sleek, trendy design. This phone has an all-metal case, which gives it its dull shine. You can find this device in gray, black, and blue. What’s more, the K40 is MIL-STD 810G-certified, which makes it dust and waterproof. The build is also reasonably sturdy, so it won’t shatter easily.
