Third-party reviews

What customers like about CUBOT A40 4G (4GB + 64GB)

  • Considered very affordable and great value for the price.
  • Screen is smooth (120Hz refresh rate) and sharp for its class.
  • Impressive battery life; easily lasts a full day with heavy use, or two days with moderate use.
  • Performs basic tasks, multitasking, and even gaming smoothly thanks to the Octa-Core processor and good optimization.
  • Features NFC for Google Pay and other contactless payments.
  • Attractive, slim design with a premium feel.
  • Comes with a generous amount of RAM and storage (up to 12GB+256GB options).
  • Includes dual speakers for an immersive audio experience.
  • Runs on a newer, smart, and intuitive Android 15 operating system.

What customers don't like about CUBOT A40 4G (4GB + 64GB)

  • Camera performance is poor in low-light conditions due to the lack of stabilization and budget-level sensors.
  • Video recordings can be shaky and lack quality due to the absence of optical stabilization.
  • Photos can appear blurry or have oversaturated colors, especially in non-ideal conditions.
  • No fast charging support; a full charge takes approximately an hour and a half.
  • The micro-SD slot shares the tray with the second SIM card slot, so dual SIM and expanded storage may not be possible simultaneously.
  • Does not have a 3.5 mm audio jack.
  • General build quality might mean the phone doesn't last as long as higher-end devices, though this is expected given the price point.

Verdict

The CUBOT A40 4G (4GB + 64GB) is an affordable entry-level smartphone running on Android 15 with a Unisoc T606 Octa-Core processor, 4GB of RAM, and 64GB of expandable storage. Its main pros include a large 6.88-inch HD+ display with a smooth 120Hz refresh rate, a high-capacity 5100mAh battery, a decent 48MP main camera and 16MP front camera, dual speakers, and useful features like NFC for payments. However, some cons include the lack of a 3.5mm headphone jack and a fingerprint scanner, a potentially mediocre camera in some lighting, and generally slow performance compared to higher-end devices.
