Not sure if anyone has mentioned this tip.. But, I loosened the aluminum screw that holds the tablet/phone bracket (which we all know is a PITA) and put some loctite (the blue "medium" type) on the threads. Then, I screwed it back on tightly, using a small wrench for extra grip.  No more wobbly bracket now.  

Great that you found a solution！

Hey DJI-Tim. I just received an Inspire 1 metal mounting bracket, but it didn't come with a screw for the bottom mount. I'm thinking they expect us to use the one that comes from the old mount, but the screw size is different. Can you tell me if the Inspire Mount was supposed to come with a new screw? It came with a screwdriver?
Ahhhhh, never mind. I found it. Can you guys hide it any better?    Sorry for bumping this up.

Thanks!   Barney

I am missing my lower screw on the standard adv/pro mount, can anyone post up a link to where I can buy one please, UK if possible ....i thanks you.
