Frequently Asked Questions

I am only giving readers my own personal experience with the following products on this page. As I do not manufacture them, I have no control of their quality or reliability and therefore you buy them at your own risk.

Where should I buy the necessary bluetooth cubes?
The first CubeSmith users had Giiker i3S cubes (the same that came with Rubiked), but recently the newer Xiaomi model got more popular (due to it's long lasting button battery and the low price). CubeSmith also supports the GAN 356i and the GAN 356i Play cubes.

Some of my users are offering a limited stock of modified Xiaomi cubes for sale ($55/cube). Please click here for more info!

Which bluetooth earpiece do you recommend?
CubeSmith sends the audio to your earpiece/headphone through the media (music) channel. All wired headphones are supported. As for bluetooth, only devices with A2DP capability are supported (if you play music and you hear it, then it will also work with CubeSmith). Here are some equipment you should consider buying:

Mini bluetooth earbud (~$20): click here
My favourite is this standalone but slightly visible earpiece, which can't be seen from the front (so you're covered about 250 degrees). You can steal it in/out while you turn your back to the spectator (to solve the cube behind your back), or you can hide it in a blindfold. The earbud connects automatically when you take it out from the holder box, and starts charging when you put it back.

Wired induction neckloop + micro earpiece (~$20): click here
This is a 2-part set: the neckloop is connected to your phone with a 3.5mm plug, and generates an electromagnetic field received by the invisible earpiece. Volume is decent, earpiece battery lasts for about 2 hours.

AGGER Ultra Box Lite (bluetooth module + earpiece) (~$99): click here
This is the most advanced and most expensive of all (also a 2-part set). The wireless bluetooth module has to be close (10-15cm) to your ear, where you put the 4mm nano earpiece. Volume depends of the distance and affected by turning your head. You can also use this bluetooth module with the micro earpiece from the above set.

Chinese hidden spy earpiece (~$16): click here
This is an earpiece only, which you can use with any neckloop or wireless inductive BT module. I recommend using this earpiece with the Agger box module Lite (see next item). Usually they don't include a battery with the earpiece, so I recommend buying them separately. The battery type is 337 (SR416SW), you'll find cheap ones on Aliexpress (click here).

AGGER box module Lite (~$45): click here
This is only an inductive BT module (with A2DP feature). You can use any inductive spy earpiece with this module, I recommend using this with the Chinese earpiece (see above).

How do I get rid off the "G" sticker on the yellow/orange center of my Giiker cube?
The "G" sticker is just an extra sticker with transparent background. Just find it's edges and gently peel it off the sticker.

How can I cover the charging holes on the green/blue center pieces?
How can I re-sticker the cube to give it a more authentic look?
You should re-sticker the cube to cover any charging holes, and also to give the cube a more authentic look. You can use any 3x3x3 sticker set, even with different color shades. Here is the sticker set that I recommend:

My custom sticker set from Oliver's Stickers: click here

Here is how I re-sticker a full side of the cube:

How can I charge the Giiker cube once the holes are covered with new stickers?
Simply take off the covers from green/blue center pieces with your fingernail (or using a flat screwdriver), then attach the charger to the uncovered sides. Push the covers back when finished charging.

How can I change the button battery in the Xiaomi cube?
The Xiaomi cube has a replaceable CR1632 button battery which should last 365 hours of active usage. If the battery is weak (20% or below) you should replace it. The battery compartment is underneatg the white center piece, so you should remove some pieces from the white layer to get access. You'll need a small X-headed screwdriver to unscrew the lid. Please watch this video that shows you the whole process:

The virtual cube in the app doesn't show the state of the actual cube. What can I do?
When fully discharged (or sometimes even randomly) the cubes reset themselves, which means they will consider their actual state (pattern) as the solved state. In this case you have to manually solve them, and then perform a "solved reset" within the app (open the Details sheet of the cube, and scroll down to find the RESET button), or use the "coloring reset" in the stock Supercube app. If this happens more than once when they are charged, then the cube might have a faulty component. It seems that about 3% of the cubes have this issue once or more. My advice: always store your cube(s) in a fully solved state, so if they ever get randomly reset, there will be no trouble at all.
The cube makes a loud clicking noise when turned. Can I get rid of this sound?
The sound is made by the loose magnets inside the pieces. You can take the edge pieces apart and superglue the magnets in, and the cube will sound like a normal cube. (You can leave corner pieces as they are.) Here is a short video tutorial on the process:

I've enabled the Audio Guide but I hear nothing (volume is turned up). How can I fix it?
This happens on Android phones, where the default text-to-speech engine is not set to Google. Go to your phone's "Settings", and search for "Accessibility" -> "Text-to-speech". Set the engine to Google, and also install the desired language and voice pack. Go back to CubeSmith, then disable and re-enable Audio Guide, and you should hear the "Welcome" speech.
Audio Guide is working, but the pronunciation is strange, like the speaker is from another country. How can I fix this?
First of all check your in-app settings: go to the section "Audio Guide" and make sure you've selected the correct language. If the problem still persists, go to your phone's "Settings", and search for "Accessibility" -> "Text-to-speech". Most likely it is set to a different language, so make sure you install and select the desired language and voice pack. Go back to CubeSmith, then disable and re-enable Audio Guide, and you should hear the "Welcome" speech in the desired language.
