It changes up and down randomly by 5 degrees or so. Does anyone know if this is a problem with LC or with galaxy phones? My iPhone does not do this.

My Galaxy S5 does the same thing with a LC compass I made. My guess is 
that's the way Android reads GPS data. When it tries to find my house, 
it does a whole bunch of hops around the circumference before settling 
down on the center, and even then it still twitches as it tries for more 
accuracy.

A compass I downloaded from the Play Store does not do that on my Pixel. 
I'd guess that the app is doing some rounding to the nearest integer, 
since it doesn't display fractional values.

Try downloading a few of the dozens of compasses on the Play Store and 
see how they behave. It may be that LC is actually more precise than you 
want it to be. I do know that LC is only reporting what the OS tells it.
