What is your numbers just above Tram?
This computer has no steer PCB or GPS but first number should tell Gps speed (10 and after snake you have time of frame rate(High is bad)
Yesterday on my tractor AOG ver 5.45 I had a similar issue, where tablet suddenly got slow (windows probably doing something in the back, (and I could not catch what) and the numbers changed from 10 snake 9(working good), to 5or 7 snake 18 and steering stopped working properly. (making at steer to left, waited 2 seconds and then steer right )
Restarted AOG and it worked again.
Some months ago I found that such a thing happened, when passing a neighbor who had a wifi (not even open) that my tablet tried to connect and windows started some security program update but obviously could not (and not a windows update)
Should add: My f9p gps is connected by bluetooth
Also this does not happen every day.
Click on speed to get this information!
I can read in my own message that I probably need to do the CCleaner trick again!
