Thanks Duane and Andy,
Andy – just trying to understand. The meter worked fine for a few months, then stopped working with your phone, BUT Mooshimeter still works connected to a Galaxy S4 mini?
So the problem is between specific phone and the meter? The time I have seem a problem like this is when Android tries to pair with the meter and fails, but keeps the faulty bond in long term memory. Can you go to Settings->Bluetooth->Paired Devices? If the Mooshimeter is listed under paired devices, can you delete it?
I hope this helps, please let me know if you learn more details.
