Hey guys, I seen plenty of threads on this but nothing up-to-date. I keep having the problem of the go 4 app crashing mid-flight and also when it is working serious lag on the whole deal. I'm talking map is way behind ,altitude, speeds, camera on off. You name it, it's sometimes 30 to 45 seconds behind when it is working. I keep getting the "unfortunately go 4 has stopped" with a black screen then have to hit return to home and thank goodness everything worked out every time so far but it's getting real frustrating. I've uninstalled ,reinstalledand made sure all my updates and firmwares are up-to-date and just can't figure it out. I've done everything I know of. Has there been a concrete solution from the earlier posts regarding this issue cuz I know I haven't been the only one. Thanks guys.
