Is gyroscope in Samsung Galaxy S5 able to detect the phone position even when phone is not moving? I installed Gyroscope Explorer and according to this it looks like gyroscope, unlike accelerometer, is able to detect the phone position regardless that phone is still.
Probably using the compass sensor

Did you mean that gyroscope is not able to detect the phone position when phone is still, but it's able to compensate this with compass?

I have a few apps that rely on an accurate compass (Geocaching, etc.). Not only is my Epic clueless as to the true heading, but it doesn't rotate as I do. In other words, if I'm facing east and turn around, the phone still reads east.
I know there are issues with the GPS, but I wonder if I have something else going on.
There is a separate magnetometer sensor, so the main compass functions that way. And most apps that show compass bearing use that.
Some apps may not align automatically by the compass bearing.
Make sure your magnetic compass is calibrated.

Thanks. I'm a dummy. I've never did the figure eight dance long enough. I figured you did it for a while and then hit OK. I continued until the prompt disappeared and it appears to be better.
Just recently acquired a MyTouch4g for my wife. Tried using Google Sky Map but it was locked onto one screen view. Even using our finger to navigate, the screen didn't move. Also tried using GPS Status to calibrate the compass and it is frozen at due North. Looked at the user manual but I don't see any way to unlock the compass so that it will work other than turning Compass Mode on in Street View of Google Maps. And that didn't work either. What am I missing to make the compass work. Thanks in advance.
Well, it looks like I was able to determine the problem. The accelerometer in the phone is not working. Even with the auto-rotate checked, the screen does not flip for navigation or viewing pictures in the gallery. Looks like I will have to exchange the phone for another that works.
Edit: Upon further investigation, I found that when my wife's new flip case arrived, the temporary case which we knew blocked the proximity sensor, was actually the cause for the Compass, Google Sky Map, Navigation problem. Once the proximity sensor was clear, the compass, Google Sky Map, etc. now works properly. Didn't realize that blocking the proximity sensor causes compass, etc. issues. Just an FYI for others experiencing compass issues.
Hi there,
I'd like to know if everyone has to hold the screen perfectly perpendicular to the floor to get it to turn. It doesn't turn for me when i hold it in my hand and turn it? Is it normal because we don't have a gyroscope or is there something else?
Thank you
Nope, when i hold it at a tilt it turns just as fine. Gyroscope is for acceleration measurements, not for facing (which is gravity, not inertia based). How would you even use a gyroscope to turn the screen? You would have to GUESS a new facing from momentum and duration of said momentum.

Mine seems to work as it has in other phones, I don't need to hold it perfectly perpendicular to the floor or anything.
The gyroscope doesn't come into play (ha, get it? ) as phones use an accelerometer and not a gyroscope to determine orientation.
So what can I do to fix this? Buggy sensor firmware? It's like that even with stock.
Using AndSensors it seems the sensor readings are fine. one could definitely implement some detection routine using them. So where to look why the sensor doesn't seem to be read?
Exactly as title says. Anyone else have the official clear view case from Samsung? Does AOD work when your cover is closed? Would be pretty convenient and for some reason Samsung decided not to include this handy feature...
It's a limitation I think.
AOD require light sensor, proximity sensor and some other sensor to work. The cover render these sensor useless and then may cause problem with AOD, so that's what I think why samsung disable it.

Well the proximity sensors work when talking on the phone with the cover closed... Seems like to me this can be implemented with a minor update.

Are you sure?
I'm not sure about how this kind of case work on new device but I used to have S-view case on my old s4 and it doesn't use proximity sensor to turn display off when calling with cover closed but use motion sensor to detect the movement of the phone to guess whether I'm holding my phone close to my face (and it fail sometimes)
Maybe you can test this by placing your phone on the table when recieving call. Without moving the phone, try cover the proximity sensor and see whether the screen is off.

You are correct sir, it does not use the proximity sensors when the clear cover is on. But even with that, it uses the phone's other sensors to wake and sleep the screen... Why can't this be applied to the AOD? Just a little thing that would be nice to have.

Because AOD use proximity sensor to detect whether your phone is in the pocket and turn itself off to save battery. Motion sensor can't do that. Also for motion sensor to detect your movement it need to be on all the time, thus massive battery drain.
Is their anyway I can use some sort of Virtual gyro sensor on this phone to play certain games that need it. I'm on a custom ROM if it makes a difference.With all these sensors cant gyro be emulated?
