PROS

  1. Extremely Compact Design: Features a 5.9-inch display, making it very easy to hold and operate with one hand.
  2. Top-Tier Performance: Equipped with the powerful Qualcomm Snapdragon 888 5G chipset, offering flagship speeds.
  3. 120Hz AMOLED Display: Provides a smooth, bright, and vibrant viewing experience with 1ms response time.
  4. IP68 Rating: Offers superior protection against water and dust, a rare feature in smaller, compact Androids.
  5. 3.5mm Headphone Jack: Includes the classic audio port, which is increasingly rare on modern flagship smartphones.
  6. Solid Main Camera: The 64MP Sony IMX686 sensor with OIS takes excellent, detailed photos.
  7. Clean Software Experience: Runs a near-stock Android experience with useful additions in ZenUI, resulting in minimal bloatware.
  8. Durable Build: Uses Corning Gorilla Glass Victus on the front, offering better drop protection.
  9. Good Stereo Speakers: Features loud and punchy dual speakers tuned by Dirac.
  10. High RAM Configurations: Available in up to 16GB LPDDR5 RAM for intense multitasking.

CONS

  1. No Wireless Charging: Lacks support for wireless charging, a common feature in phones at this price point.
  2. Overheating Issues: The Snapdragon 888 chip tends to get quite hot under heavy loads, such as gaming.
  3. No Telephoto Lens: Only features a dual-camera setup (main and wide), lacking a dedicated zoom lens.
  4. Average Battery Life: Despite a 4,000mAh battery, it struggles to last a full day under high-performance usage.
  5. No MicroSD Slot: Does not allow for expandable storage, restricting users to the internal 128GB or 256GB.
  6. Slow Fingerprint Scanner: The optical, under-display fingerprint sensor is reported to be hit-or-miss in accuracy.
  7. Slippery Matte Finish: The frosted glass rear is quite slippery, often requiring a case for a better grip.
  8. Limited Software Updates: Only two years of major OS updates and security patches are guaranteed.
  9. Awkward Headphone Jack Position: The 3.5mm jack is located on the top edge, which can be awkward for cable management.
  10. Motherboard Issues: Some users have reported premature, random failure of the motherboard (known as "dead boot" or ramdump).
