    Upgraded from 1.08 to 3.2 yesterday and I noticed that the GPS icon on the lower left corner switches rapidly from GPS To ATT. It only does it in GPS, stays the solid in ATT or Manual. I downgraded to 1.08 and the status is solid in all three modes. I havent flown yet but I am little worried. I did the upgrade because my Quad was all over the place when I first top off.
    Here is a quick video of the issue.

    I had this exact same issue until I switched to NAZA mode. It seems to go away and stay rock solid as GPS once I am actually outside and the unit is idling and has a good quantity of satellites.

    For good measure, I would suggest doing your advanced IMU calibration, taking it into a field, turning on your P2 and letting it sit there for a couple of minutes, do your compass dance, ensure the compass dance calibration took ok. Take it for a 10 foot test flight.

    I think you'll find that this issue goes away once you're in the field and the P2 has got a GPS lock.

    tferrari - I did a advanced IMU Calibration and I always do a Compass dance before I put my bird in the air.
    I am going to check but I am 99% sure I am already in NAZA-M mode but I will double check before I head out to check.

    GorData,

    I just tested this again. When I don't have at least 6 satellites, my GPS icon will flash between GPS and ATT.

    Try it outside again and see what happens once you get 6 or 7 satellites.

    What GorData said is correct...the Phantom automatically switches to ATTI mode when it doesn't have enough satellites locked (at least 6) to maintain solid GPS position hold.
