Editorial report
LG K42 technical sheet
The LG K42 suits buyers after a basic phone with expandable storage; the main trade-off is a battery and charging setup weaker than those of most phones launched around the same time. Its 4,000 mAh battery supports 10 W fast charging, both below what most phones of its time offer.
The 6.6-inch IPS LCD display has a resolution of 720 × 1600 px and a density of 266 ppi, lower than that of most phones launched around the same time. A MediaTek Helio P22 pairs with 3 GB of RAM and 64 GB of storage, less memory than most phones of its time offer. Storage can be expanded. Its AnTuTu score of 94,000 is also worse than that of most phones launched around the same time.
Four rear cameras cover different kinds of shots: the 13 MP main camera records 1080p video at 30 fps, alongside an ultrawide, macro and depth camera. Connectivity includes NFC, USB Type-C, a 3.5 mm audio jack and Dual Nano-SIM. Its camera, battery and performance are worse than those of most phones launched around the same time, while its display and connectivity are below average. At 182 g, it weighs less than most phones of its time. With a NeoScore of 3.8, the LG K42 is a basic option for buyers who value expandable storage and essential features.
