Has anyone had problems with the new update to version 1.2.6 on the Phantom 3 Professional? My Phantom was rock solid with the last version but after I took a flight with it and charged up the battery to do the new Firmware and then took another flight and it is bad. I can't fly it now close to anything like I did before. It wanders 1 to 2 feet back and forth and side to side.  I just updated it today. Yesterday I had some good strong winds here and was not sure I was going to even try to fly it but thought what the heck. I was amazed at how steady it was in the wind. This copter is amazing and I have NOT crashed it at all. I love it but now I have to put it in the box until they get a new update to fix it.

Anyone else having this problem?

I've updated the firmware but haven't flown yet, hasn't stopped raining here for the past week!  It does look fine in the Pilot app and takes photos with no issues.  Hopefully will test fly it in a couple of days or so.

Did you recalibrate your compass and the IMU ?

I have Recalibrated everything that I could and still it floats and drifts all over the place. It does it so much that it shows on my videos . It is frustrating as it only started after this new update.

Joe, can you pls send your flight log to support? I'll send a form back to you to fill.
It will help a lot for us to find out the cause and reach a solution.
