Can anyone help me understand what is causing this issue?
Last week i told my dji mavic to a mountain flew it 25 feet out and 50 feet up, the connection between my phone and the drone camera disconnected then comes back then gone, but 8 still have control over it with the controller.  I couldnt see anything on my phone its saying disconnected.  I moved higher in the mountain with a cliff and it was spotty the camera would show picture then no picture or its not clear.  
I wondering if it was the last update that messed up.  It was not like this before the update and me bringing it to the mountains.  

What mobile device are you using? What is the APP version? When you say "It was the last update", what update are you referring to, firmware or APP?

Same issue after upgrading to android app 4.1.15
