Reviews for the LG K40

81.7% LG K40 Smartphone Review: A cheery and affordable handset | Notebookcheck
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.
Hands on: LG K40 Review
Source: Trusted Reviews English version
An unassuming affordable mid-range phone that features a surprising amount of technology but throws up performance concerns and doesn't look like it can compete with rivals from the likes of Motorola.

The LG K40 is far from the most exciting phone announced at MWC 2019, but if you're looking for a budget phone this may sport enough tech for you.

It is a very small display format for smartphones. You should by no means be mis-sighted and you will generally see very little on the screen and only have a small resolution available. In return, the device should be very small and handy.

LG Electronics Inc. is a subsidiary of LG Group. It is a South Korean company and was founded as Goldstar Co, Ltd, in 1958. The group offers products in the fields of information technology, consumer electronics and mobile communications, and home appliances. LG Electronics is the world's third largest home appliance manufacturer. As a notebook manufacturer, LG only became known to a wider audience in the German-speaking market in 2005. After a few years, LG largely withdrew from the laptop sector. The product range includes OLED, LED/LCD and plasma TVs, home theater systems, Blu-ray players as well as audio and video players. 

65.9%: This rating is poor. More than three quarters of the models are rated better. That is rather not a purchase recommendation. Even if verbal ratings in this area do not sound that bad ("sufficient" or "satisfactory"), they are usually euphemisms that disguise a classification as a below-average laptop.
