Compasses in Multi-Player MCPE don't work

We are playing in an infinite world created on a Galaxy S5. The person on this device has a working compass that points at the spawn point. Others who have logged in with S3, S4, and Motorola Electrify have compasses that point at a seemingly random point(s) in the world, so they are unable to find the spawn point and return to it. We have tried restarting all the devices, and that did not change anything. All devices are using v.0.9.5.
