What we like about LG K40s (2GB + 32GB)

  • Competitive price point and high affordability
  • Strong battery life, with some users reporting up to two days of use
  • Durable build quality with MIL-STD-810G military-grade certification
  • Compact and lightweight design that is comfortable to hold
  • Includes useful legacy features like a 3.5mm headphone jack and FM radio
  • Dedicated Google Assistant button for quick voice commands

What we don't like about LG K40s (2GB + 32GB)

  • Frequent performance issues, including freezing and lag over time
  • Poor gaming performance; struggles with modern titles even at low settings
  • Low camera quality, particularly in low-light conditions
  • Limited internal storage (often 16GB or 32GB) that fills up quickly
  • Slow charging speeds due to the older micro-USB port
  • Outdated software support, with many units stuck on Android 10 or older

Verdict

The LG K40S (2GB RAM + 32GB storage variant) is an entry-level smartphone featuring a 6.1-inch HD+ FullVision display, powered by an unspecified octa-core processor (often listed as 2.0 GHz) and runs Android 9.0 Pie (upgradable to Android 10). A key advantage is its dual rear camera setup, comprising a 13MP main sensor and a 5MP Super Wide Angle lens for versatile shots, along with a decent 13MP front camera. It includes a 3,500mAh battery, DTS:X 3D Surround Sound support, and a dedicated Google Assistant button. On the downside, typical cons include limited internal storage (quickly consumed by the OS and apps), basic display resolution, modest performance due to only 2GB of RAM, and the use of a micro-USB charging port instead of the more modern USB-C.
