Design and Build

The LG K31 exhibits a minimalist and practical design catering to users seeking functionality over opulence. Its dimensions, measuring 147.8 x 71.1 x 8.6 mm, offer a compact form that comfortably fits in the hand, making it easy to handle and carry around. Weighing just 146 g, the device is lightweight, which enhances its portability. The matte gray finish provides a subtle aesthetic appeal, ensuring it holds its ground in terms of style without being overly flashy. It supports Dual SIM (Nano-SIM, dual stand-by), a feature advantageous for users managing multiple networks.

Display Quality

A 5.7-inch IPS LCD graces the front of the LG K31. Though not the largest in its category, the display offers adequate real estate for basic media consumption and everyday tasks. With a resolution of 720 x 1520 pixels and an aspect ratio of 19:9, users can expect a decent viewing experience with a pixel density of approximately 295 ppi. The screen-to-body ratio of 77.2% indicates fairly thin bezels providing more immersive views, though not as seamless as those seen on modern edge-to-edge displays.

Performance and Software

The LG K31 is powered by the Mediatek MT6762 Helio P22 chipset, featuring an octa-core Cortex-A53 processor clocked at 2.0 GHz. While not a powerhouse designed for intense gaming or multitasking, this combination is competent for everyday applications, browsing, and light gaming. Furthermore, the device runs on Android 10 coupled with LG's UX 9.1 interface, ensuring access to updated features and security. The inclusion of a PowerVR GE8320 GPU supports basic graphic tasks, optimizing media playback.

Storage and Memory

With 32GB of internal storage onboard, the LG K31 offers a moderate amount of space for apps, media, and files. However, recognizing potential storage limitations for some users, LG has provisioned a microSDXC slot, allowing expansion and giving users added flexibility. The device is equipped with 2GB of RAM, which is satisfactory for basic operations but may show signs of strain during heavy multitasking or with particularly demanding applications.

Camera Capabilities

For photography, the LG K31 features a dual-camera setup at the rear comprising a 13 MP primary sensor and a 5 MP ultrawide lens. The primary lens, with an aperture of f/1.8, captures detailed images even in low light, thanks to PDAF (Phase Detection Autofocus). The secondary 120° wide-angle lens enables capturing broader perspectives, suitable for landscapes or group photos. Photography features such as LED flash, panorama, and HDR enhance the versatility of the camera. Video recording supports 1080p at 30fps, allowing for decent video capture. On the front, a 5 MP selfie camera meets basic video calling needs and casual self-portraits.

Audio and Connectivity

The LG K31 comes with a built-in loudspeaker and a 3.5mm audio jack, which is a handy feature for users who prefer wired headphones. For connectivity, the smartphone supports Wi-Fi 802.11 b/g/n, Wi-Fi Direct, and Bluetooth 5.0 (A2DP, LE) for efficient wireless communication. GPS support is available for location services, while the absence of NFC and FM radio may be a downside for some users. Charging and data transfer are conducted through microUSB 2.0, which, while not as fast as modern USB-C, remains widely usable and compatible.

Battery Life

Powering the LG K31 is a 3000 mAh Li-Ion battery, which is non-removable. Given the relatively modest hardware, this battery capacity can comfortably last a full day of typical use. While it does not support fast charging, the battery life management optimizations in Android 10 help conserve power efficiently.

Security and Additional Features

The inclusion of a rear-mounted fingerprint sensor enhances device security, allowing for quick and easy access while keeping the device safe from unauthorized entry. Additionally, the accelerometer sensor augments functionality in motion sensing and user interface navigation.

Pricing and Value

Released in August 2020, the LG K31 was made available for about 130 EUR, positioning it within the budget segment of the smartphone market. This pricing makes it an attractive option for users seeking a reliable smartphone without extravagant features, appealing particularly to those who prioritize day-to-day functionality.

Conclusion

Overall, the LG K31 presents itself as a solid budget smartphone, catering to users requiring essential features for modern mobile communication. Its balanced approach to design, utility, and affordability makes it a commendable choice for those entering the smartphone ecosystem or needing a reliable secondary device. Despite its limitations in higher-end features, the LG K31 holds its ground firmly within its intended segment.
