Inspire-1 with firmware v184.108.40.206 -- DJI APP with version 220.127.116.11 (Android) -- Tablet Samsung Galaxy TAB S 8.4" Question posted to DJI Technical Support: "" After flying two batteries, with perfectly normal flights, i stopped for a break. When i restart (first thing to do is launch the DJI APP), the application disappeared from the "App's Screen" and the Tablet went into "Security Mode". Samsung says that if the "Security Mode" went on, it's because there's same kind of a problem with the application. Then i have to go to "Application Manager" and uninstall the application. After this, the "Security Mode" went off. I than reinstall the application and everything it's ok. But the question remains - Why did it happen???. How to avoid this in the future??? "" Replay from DJI technical support: ""1. Exit the "Security Mode". 2. Make sure you did not install some "security protection" APP that may automatically stop the working of the pilot APP. 3.If the previous two method do not work, please kindly select "Restore factory settings" to see if problem can be solved."" Obviously the DJI Technical Support is not bothered wiyh the problem.
