Flashes of brilliance. The LG K40 is an affordable smartphone that includes a few tricks, such as DTS-X sound support. However, has the South Korean manufacturer focussed too much on flashy features and forgotten to get the basics right? Our rigorous tests will reveal all in this detailed review. LG refreshes its affordable K series annually. Last year, we reviewed the LG K9 and LG K11, which were both budget smartphones. This year, the South Korean manufacturer has positioned its K series against the Samsung A series, with the K40 being the focus of this review.

LG K40 is a mid range smartphone launched by LG in the month of Feb 2019. The MWC (Mobile world congress) is shaping up quite busy this year.

LG K40 is a mid range smartphone launched by LG in the month of Feb 2019. The MWC (Mobile world congress) is shaping up quite busy this year. The LG K40 comes with a full metal unibody design, and so far we think there’s only one color available – the blue you can see in the photos around here.
LG may decide to include more colors in the future, but we’ve only been able to see the blue version of the phone. It’s an attractive color, and while the phone doesn’t feel particularly premium it does sit in the hand comfortably. It doesn’t compare to products like the Moto G7 though with its glass back and rounded edges, but at 8.3mm thick you’ll find this slips into your pocket with ease.
OS and specs: LG is offering Android 9 Pie software right out of the box here, and it’ll come with LG’s overlay on top that makes it look somewhat different to other Android manufacturers user interface.
Battery and camera: The K40 sports a 3000mAh battery, and considering this isn’t the most spec-laden phone, this should power the phone for at least a day from a single charge.
We don’t know for sure yet, and we’ll be sure to put it through its pace during our upcoming full review. On the rear of the handset is a single 16MP shooter. That isn’t set to blow you away with its photography skills, but if you’re looking to take the odd shot to upload to social media it should be able to get you by.
