What phone model? and what error?
also on lates android build, knowing issue if you app swiped out from activity list, you probably could lost connection, fixed but not released yet.
in general race for BTLE connection between suunto app and live.τ app still exist, but observation said that it’s not a big deal, and connection works in general well. personally i usually lost connection in some difficult areas near military objects, or radio polluted regions… not sure if it’s your case.
