I really like my Spark but everytime I use Active Track or Quick Shots the GPS looses up to 5 Satelite and most time switch to vision mode. I use the 01.00.0300 firmware because with 0400 the video latency is about 1 Second and more.
I figured out when I remove the SD Card everything works fine.
Any suggestions or upcoming firmware to fix this problem?

The SD card is the one coming together with Spark, right?
