Editorial note

The LG K40s stands out with several interesting features that make it a relevant choice for users looking for an affordable smartphone. With a 6.1-inch display and a resolution of 1560 x 720 pixels, it offers a pleasant visual experience, although this may seem limited for fans of high-definition content. The internal storage capacity of 32 GB, expandable up to 2000 GB via a MicroSD card, allows for a large amount of data and multimedia files to be stored. Regarding performance, its 8-core processor running at 2 GHz ensures smooth usage for daily tasks. However, the 2 GB of RAM may lead to slowdowns when multiple applications are used simultaneously. The 3500 mAh battery is a major asset, providing appreciable autonomy, ideal for active users. In terms of design, the LG K40s has a modern and ergonomic look, although the screen could have benefited from a better resolution for an optimal multimedia experience.

In summary, the value for money of the LG K40s is fair, but its limitations in terms of RAM and display quality make it less competitive compared to other similar models on the market. It is a solid choice for those who prioritize good battery life and expandable storage capacity.
