When I try and set the home point to the remote location, a "weak mobile signal" comes up on the tab and I can't do it.......... I can press the other icon to set the homepoint to the drones position with no problem.  "Follow me" also has similar problems.............         Everything else works perfectly so this isn't really a serious problem. Is this just caused by the mobile device I'm using.... a Samsung Galaxy Tab 4............ if so, is there anything that can be done about it other than change the tablet to a different one?    Many thanks.
