M7 Vibrates When Changing Connection Between 2G, 3G And H+

Hi,

after changing my ROM to CM12.1 my M7 always vibrates when changing the data connection between 2G, 3G and H+

I wiped data, system, cache and dalvik after as i changed to nightlies and im wiping cache and dalvik on every nightly upgrade.

I got this issue on every nightly i installed after changing to CM12.1

Is there any known fix to this issue?

Best regards
Knexi
