Display Comparison

The LG K42 boasts a larger 6.5-inch display compared to the K8's 5.3-inch screen. While both utilize IPS LCD technology, the K42's larger size provides a more immersive viewing experience for media consumption and gaming. Resolution is likely similar, but the K42's size advantage is noticeable.

Camera Comparison

The LG K42 typically features a triple-camera setup (13MP main, 5MP wide, 2MP depth) offering more versatility than the K8's single 8MP camera. While image quality on both phones is decent for the price, the K42's additional lenses allow for wider shots and better portrait mode effects. Low-light performance is likely better on the K42.

Performance

Here's where the K42 shines. Its Mediatek Helio P22 chipset and Octa-core CPU significantly outperform the K8's Snapdragon 210/425. Expect smoother multitasking, faster app loading times, and a more responsive user interface on the K42. The K8 can feel sluggish at times, especially with demanding apps.

Battery Life

Both phones offer adequate battery life for a full day of moderate use. The K42's larger battery capacity (5000mAh) gives it a slight edge over the K8 (likely around 3000mAh). However, the K8's less power-hungry processor can help offset this difference.

Buying Guide

The LG K42 is ideal for users who prioritize performance, a larger screen, and a more modern design. The LG K8 (2018) is a good choice for those seeking a very budget-friendly option, a smaller phone for easier handling, and don't need the latest features.
