Just found you guys because of this problem. Looking forward to hopefully posting some good and helpful hints here after I figure this problem out. I just installed the F800 with the rear camera. All went well up until I try to download a file to my phone. It tries and gets about 3/4 of the way on the download and losses the wifi connection. I can keep the connection active and see the live imaging for as long as i want, it is just as soon as i try and save a file it quits! Any thoughts?
