FAQ & Support

It does not work with my Android device?

We are sorry to hear that, but unfortunately we do not support Android devices.

Why?

Our devices connect either via the Apple's Lightning port or the audio jack. The former is an established standard across all modern iOS devices and enables us to focus our R&D on one, unified port. It also certainly looks like it will stay that way for a some time.

The latter has a constant power delivery and a unified communication protocol, which is not consistent between various Android manufacturers and their models.

Our past experiences have shown that it is best practice to focus on one platform & make it perfect. Only then we'll be ready to support another one.

Having said that, we are also very much looking forward to the moment when the USB type-C will be adopted by all / most Android manufacturers. It will certainly make our lives easier.

Have you bought your Lumu thinking it will work with your android device? Don't worry, send us a message, we'll arrange a DHL pickup and once we receive it, we'll refund you in full. Write us: support@lu.mu.

The Lumu Light Meter works on all iOS devices. Lumu apps require iOS 7 or newer.

Can Lumu measure flash strobes?

The Lumu Lite (first version) meter does not measure flash strobes but our new Lumu Power is be able to do that, amongst other new features. Read more about it.

Send us an email if you have any other feature requests for your perfect Lumu experience.

My Lumu Light Meter does not fit on my iPhone case. Can I use an extension?

Apple Compatible

Lumu was designed to be compatible with all official Apple cases. There should be a distance of 2mm between the Lumu casing and the audio connector. If you think that the distance is shorter on your device please send a photo of the Lumu attached to your iPhone to support@lu.mu and we will assist you.


Other bumpers/cases

If you use one of the other case types and your Lumu does not fit on it, you can also use an extender. The extender must be the 4 pole version.

You can use a short extender (this or that) or you can use an audio cable extender, which can measure up to 1m (approx. 3ft) in length.

Here's another great 4 pole headphone jack extender.

 

My Lumu stopped working

We are sorry to hear that!

It is a rare occasion that a Lumu stops working, so please try to diligently follow these steps first:

  • Which iPhone and iOS version do you use? Lumu only works on iOS7 devices or newer.
  • Did you enable Lumu microphone permissions (found in Settings / Privacy / Microphone / Lumu)? 
  • Did you turn off the Volume Limit? Go to Settings / Music / Volume limit and make sure it's turned off.
  • Did you turn off the Mono Audio option? Go to Settings / Accessibility / Mono Audio and make sure it's turned off.
  • Clean the audio port on your iPhone for any dirt residue.


If none of this works, we would like to ask you to do the following:

  • reinstall all your Lumu apps, or
  • try your Lumu on some other iOS device, but please follow the same steps described above first (in order to avoid any similar issues).

If none of the above fix the problem, send us an email to support@lu.mu and we'll happily assist you. Please state your name & purchase date (or the Invoice number) and if you have conducted the steps described above. Thanks.
