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.
