Problem with gyroscope on Firefox OS

I'm making a app for Firefox OS, it's going to be a game like doodle jump. So it works great on my iPhone, iPad, and Android phone, but when I try to test it on my ZTE Open C, it won't work. It says that the gamma is constantly 0. Help please!

Bump.

Bump again.

Seeing it works on android and Iphone:

If it's constantly returning 0 either the device doesn't support orientation or the app/game doesn't have the permission to acces it (could ofcourse have to do with the browser not having permission if you play in the browser)

I haven't fiddled with firefox OS myself, so it might be that the way to acces these informations works differently from other systems and the "bug" is inside the code to try and get acces..

Does the ZTE Open C actually come with a gyroscope? I think Firefox OS supports it, but if the device doesn't have it, then it can't report any values for it. It's a budget device so they might have cut the gyroscope as a way to lower the cost of the device.

Yeah, according to GSMArena: ZTE Open C sensors includes just "Accelerometer"

Compared to the Nexus 5, which lists for sensors: "Accelerometer, gyro, proximity, compass, barometer"

The ZTE Open C has no gyroscope!

If it has no gyroscope then why can i tilt it sideways and the app turns with it?

Bump

Like ashley says, it has no gyroscope:

Bumping this thread won't solve that I'm afraid..

I think you would have to ask the people that make it.

Process of elimination would suggest that if the program works on other devices, and doesn't on yours then it's probably hardware, and not software.

I really really doubt that this device doesn't have a gyroscope, since it can go into landscape mode when i tilt it.

nutcase84 - it can still determine its portrait/landscape orientation from the accelerometer, using the direction of gravity. That doesn't mean it has a gyroscope.

Can I do the same thing with my app?

nutcase84 - yes, the accelerometer expressions in the Touch object should still work on the ZTE Open C, since it has an accelerometer.
