So after much trouble shooting it's solved! This issue I think is only going to happen with the Phantom 3 Advanced series as DJI went cheap and it has hurt in areas with high temps! But the issue is solved and here's how you can fix it! It's not your tablet over heating and lagging, It's the GIMBAL CONTROLLER! After I fixed it today, in 96 degree south texas (houston) heat, I cranked my brightness all the way up on the ipad mini 4 and let her rip. ZERO lag! Tablet was as hot as GRITS (girls raised in the south) and ZERO lag! Phantom 3 Advanced Video Lag FIXED! – UAVDoc Thoughts: The issue is with the chips not making good thermal contact to the heatsink. As some have done by adding a fan and didn't help. This solved it instantly! Fan could help, but I do not believe it's needed.
