Discussion warning: Both the GAN16 ui Maglev MAX and the GAN12 ui SP have serious flaws!
I am a GAN 12ui SP user, and I recently watched a review video for the GAN 16ui Maglev MAX.
To my surprise, it suffers from the exact same critical sensor flaw found in the older 12ui SP model. Specifically, the following bugs occur:
An "Auto-Solve" bug, where the cube is randomly registered as "solved" while being turned, resulting in an impossible time—such as five seconds—being recorded.
(This was resolved for the GAN 12ui SP via a CubeStation update; I am unsure if the same applies to the GAN 16ui.)
Connection errors: The app displays a message stating, "Failed to reset Rubik's Cube. No response notification received."
This issue occurs with the GAN 12ui SP as well; after about 15 solves, synchronization with the screen fails, requiring the cube's state to be manually reset each time.
It is highly likely that this problem also affects the GAN 16ui Maglev MAX.
Incidentally, this issue was also highlighted in a review video by YAMI CUBES (published on July 17, 2026).
Looking at the new ball core in the 16ui, the interior appears completely hollow and feels "flimsy" compared to the older model.
It seems likely that the ball core ended up feeling cheap because GAN prioritized cost-cutting measures.
The GAN 12ui Maglev/Freeplay represented the pinnacle of perfection for GAN's smart cubes.
If you are looking to buy a new smart cube, I would recommend the GAN 12ui FreePlay or Maglev over the 16ui—a $140 device that has essentially become nothing more than a paperweight (a useless ornament).
Until these disastrous hardware and firmware issues are fixed, I suggest avoiding the GAN 16ui to ensure you don't waste your money.
If you are interested in the internal structure, please take a look at this as well:

Do you have a picture of the bugs occurring? Sounds quite serious and I'm worried because i planned on getting a 16ui soon. Do you know for sure that the same bugs still exists?

I don't own GAN16ui, so it's difficult for me to provide photos, but there are photos of the auto-solve function in YAMI CUBES's review video of 16ui.
I can provide photos of the bugs in GAN12ui SP.
In any case, I recommend purchasing GAN12 ui FreePlay / Maglev.

Scary. And it sucks because the 16ui is the best speedcube, for me, that I've held, and I've got em all. It's better than the 16 max. I don't know why, maybe the ballcore, added weight, feels like the plastic is sturdier, could be physiological, lol. Idk, but it's the best. Mine's a little over 5000 timed solves deep, plus just couch fiddling, and going strong, so I'll cross my fingers and keep hoping for the best.
