Report Holy Stone and Android Phone in Accessories & Other Drone Models Posted February 16, 2020 I am having trouble with the Holy Stone HS-720 receiving GPS signals from my Samsung S10e and LG-g2. When I try to activate the TapFly and FollowMe modes, I get a message that states "insufficient mobile phone GPS signal". I have tried the drone on a thrird phone with the same results. QUESTION: Has anyone found that an Android phone (model no.) works for the subject modes on the HS-720?
