Disadvantages of Samsung Galaxy M31s

  • The device is relatively heavy, weighing 203 g (7.16 oz), which might affect portability and ease of use.
  • The performance may not be the best in its class since it uses the Exynos 9611 chipset, which is considered mid-range.
  • The Android OS version is outdated upon launch (Android 10), and while it's upgradable to Android 12, newer versions are now available.
  • Gorilla Glass 3 protection is somewhat outdated in comparison to newer iterations of Gorilla Glass, which provide better scratch and impact resistance.
  • No support for 5G networks, limiting future-proofing as 5G becomes more widespread.
  • NFC availability is market/region dependent, which might be inconvenient for users who rely on NFC for payments and other functions.
  • The reverse wired charging is only 4.5W, which is considerably slower compared to fast charging standards.
  • Despite having a large battery (6000 mAh), the device could require frequent recharging due to potential inefficiencies in power management.
  • No wireless charging support, which is a convenient feature available in some competing devices.
