Display Comparison
Neither device boasts a standout display. Specifications are unavailable for both, but given their market segment, we can assume both utilize LCD panels with 720p+ resolutions. The LG K42 likely benefits from LG’s display expertise, potentially offering slightly better color accuracy and viewing angles. However, the difference will be minimal for casual users. Bezels are expected to be substantial on both devices.
Camera Comparison
Both phones likely feature modest camera setups. Without specific sensor details, it’s difficult to make a definitive judgment. However, given the price bracket, expect a primary sensor around 13MP on the LG K42 and potentially 8-13MP on the Yezz Art 3S. The LG K42’s image processing pipeline is likely more refined, resulting in slightly better image quality in good lighting conditions. The presence of a 2MP macro lens on either device is largely a marketing gimmick and offers limited practical benefit.
Performance
The core difference lies in the chipsets. The LG K42’s MediaTek Helio P22 (12nm) features eight Cortex-A53 cores clocked at 2.0 GHz. This smaller fabrication process and higher clock speed translate to better efficiency and performance compared to the Yezz Art 3S’s Unisoc SC9863A (28nm). The SC9863A uses a split core configuration – four Cortex-A55 cores at 1.6 GHz and four at 1.2 GHz. While the A55 architecture is more efficient than the A53, the larger node size and lower peak clock speeds of the SC9863A result in slower overall performance. Users will notice this difference in app loading times and multitasking. The K42 will handle basic games more smoothly.
Battery Life
Both devices support 10W wired charging, indicating similar charging speeds. Battery capacity is unknown for both, but the more efficient Helio P22 in the LG K42 will likely result in slightly better battery life, even with a similar capacity battery. The 12nm process allows the K42 to accomplish more per watt, extending usage time between charges. Expect a full charge to take around 2.5-3.5 hours for both devices.
Buying Guide
Buy the Yezz Art 3S if you prioritize a potentially lower price point and are primarily focused on extremely basic tasks like calls, texts, and light social media browsing. Buy the LG K42 if you want a smoother experience with slightly more demanding apps, occasional gaming, and a more responsive user interface, even if it means spending a bit more.
Frequently Asked Questions
❓ Will the LG K42 struggle with popular apps like Facebook or WhatsApp?
While the Helio P22 isn't a powerhouse, it's capable of running apps like Facebook and WhatsApp smoothly. You might experience slight delays when loading these apps or switching between them, but it shouldn't be a frustrating experience for typical usage.
❓ Is the Unisoc SC9863A in the Yezz Art 3S suitable for playing any mobile games?
The Unisoc SC9863A can handle very basic 2D games, but it will struggle with most modern 3D titles. Expect low frame rates and significant lag even on low settings. The LG K42 offers a slightly better gaming experience, but still isn't ideal for demanding games.
❓ How long will it take to fully charge either phone from 0%?
With both phones supporting only 10W charging, expect a full charge to take approximately 2.5 to 3.5 hours. Neither device offers fast charging capabilities.
❓ Does the LG K42 have any software features that enhance the camera experience?
LG typically includes features like Scene Optimizer and various shooting modes in their camera software. These features can help improve image quality in specific scenarios, offering a slight advantage over the Yezz Art 3S, which likely has a more basic camera app.
