What we don't like about UMIDIGI BISON X20 (12GB + 128GB)

  • The phone is heavy and bulky, which some users find uncomfortable or unsuitable for certain users like the elderly.
  • Charging is slow (10W), with a full charge taking nearly 3 hours.
  • The display is only HD+ (1600 x 720 pixels) and not very bright, making it difficult to use comfortably in direct sunlight.
  • Camera quality is described as only 'okay' in daylight, with grainy photos in night mode and lacking the dynamic range of higher-end phones.
  • Not suitable for heavy gaming due to the older Helio P60 chipset.
  • Some users reported minor, occasional software glitches that require restarting the device to fix.
  • Lack of an apparent app drawer in the default launcher caused frustration for some users.
  • It is a 4G phone and does not support 5G connectivity.

Verdict

The UMIDIGI Bison X20 is a rugged smartphone built to withstand harsh environments, featuring IP68/IP69K and MIL-STD-810G ratings for water, dust, and drop resistance. It runs on Android 13 and is powered by a MediaTek Helio P60 octa-core processor, offering 6GB of physical RAM (expandable to 12GB virtually) and 128GB of internal storage, which can be further expanded by up to 1TB via microSD card. Key features include a large 6.53-inch HD+ display, a massive 6000mAh battery with OTG support for reverse charging, a 20MP main camera, and NFC for Google Pay. Pros include its exceptional durability, long battery life, functional customizable hotkeys, and useful outdoor toolkit apps. Potential cons involve a processor that, while adequate for daily demands, is not a high-end chip for intensive tasks, and the display is only HD+ resolution rather than Full HD+.
