PROS

  1. Remarkably Thin & Light: It is one of the thinnest and lightest book-style foldables, making it comfortable to hold.
  2. Excellent Display Aspect Ratio: The 6.31-inch cover screen feels like a normal, non-cramped smartphone, not a narrow remote.
  3. Nearly Invisible Crease: The main inner display has a very shallow crease that is barely noticeable during daily use.
  4. Top-Tier Cameras: Features arguably the best camera system on a foldable, featuring Hasselblad tuning and a 3x telephoto lens.
  5. Brilliant Screen Brightness: Both internal and external screens are exceptionally bright at 2,800 nits peak, great for sunlight visibility.
  6. Open Canvas Multitasking: The software allows for desktop-like multitasking, making it easy to run 3+ apps simultaneously.
  7. Fast 67W Charging: The phone charges from 0-100% in roughly 40-45 minutes, with the charger included in the box.
  8. Solid Performance: Powered by Snapdragon 8 Gen 2 with 16GB RAM, it handles gaming and intensive tasks flawlessly.
  9. Sturdy Hinge Design: The hinge allows the phone to open and close completely flat while feeling robust.
  10. Iconic Alert Slider: Includes the signature, tactile Alert Slider for quick switching between silent/vibrate/ring modes.

CONS

  1. No Wireless Charging: Surprisingly, this premium, high-cost foldable lacks wireless charging support.
  2. Limited Water Resistance: It only has an IPX4 rating, meaning it can handle splashes but not submersion like the IPX8-rated competition.
  3. Bulky Camera Bump: The massive camera module on the back makes the phone wobble on flat surfaces.
  4. No Official Stylus Support: Unlike Samsung, there is no S Pen support or officially available stylus for note-taking.
  5. Software Bugs: Users have reported some minor bugs and occasional lagging in OxygenOS on the big screen.
  6. High Price Point: It is an expensive, high-end, enthusiast device that is not meant for mainstream budgets.
  7. No MicroSD Slot: Storage is not expandable, although it comes with a generous 512GB base.
  8. Hinge is Too "Easy" to Open: Sometimes the hinge feels too loose, making it hard to keep it propped at certain angles.
  9. Limited App Optimization: While improving, not all Android apps are perfectly optimized for the large, almost square inner display.
  10. Difficult to Repair: Due to its complex structure, repairing the screen or hinge can be difficult and costly, despite insurance options.
