I just bought the Polar H7 heartrate monitor to use with my Samsung Galaxy S5 because i was under the impression that it was compatible (saw videos and read forums about that) but my phone is not conecting with the device. It seams to detect the devise and it appaers like they are pairing all right but nothing happens after that. The H7 unit does work fine with the polar app, but if i try to connect other app like endomondo or S health it does not read the H7 signal. Any ideas? is it only my phone ( G900M )?
