GPS location & direction in Google Maps

When using Google Maps, I'll press the circle to center in on my location, and the arrow is supposed to show the direction I'm facing. About half the time, it shows me facing about 30 to 90* in the wrong direction. The arrow will move left or right as I do, but still faces the wrong direction. There have been occasions when it will show the dot and arrow moving and facing backwards while I'm driving. This hasn't affected Navigation, as it still accurately shows my location. Has anyone else noticed this, or have a solution?

What I've tried so far: Sensor Calibration under the *#0*# menu.

Also, I had this issue on my Note 4 as well.

Point me in the right direction!

Hello all!

I've been a creeper around here since 2010 (obviously not on the G4 forum), and I have just now decided to register. I got into rooting and ROM'ing with my Droid X, and now I'm a "phone enthusiast" (I suppose that's what you can call someone who irresponsibly spends money on different phones).

So I'm a third year Computer Security student at my University and I know languages like Java and C. Java, being the language that Android is based on, and C, being the basis for Linux systems, I would imagine to be very beneficial to me in Android development. Basically, what I'm trying to find is a good resource to tell me how all of the system image files work. I've had to reflash firmware plenty of times and know of the system files like system.img, boot.img, etc. and I want to know how they all work and work together.

My end goal is to be able to unlock the bootloader (which I imagine is decrypting the file and editing something within it) for the community. But, I can't even try to do that without knowing how all of this stuff works together and what exactly it means in the technical sense to unlock the bootloader.

Are there people on this forum who know or a resource to learn about this stuff, or a user who is experienced enough to explain to me how this all would work?

PS. I know there are some really smart people working on unlocking it, and I'm certainly not trying to jump in and act like I can do it. I'm just purely curious in trying to do this.

Thanks in advance!
