Very bad last update - I have IM App notifications (like Skype, Viber, WhatsApp) turned on, and now the band vibrates not only when a message arrives, but also THE WHOLE TIME, when I'm on the call. E.g. if I'm calling someone on Viber and talking for 1 hour - the band vibrates NON-STOP for 1 hour!!! This was not the case before the last update - previously the band vibrated only ONCE at the start of a call. Please fix this! It's super annoying and the band battery reduces significantly.
