Hello you all,

My GalaxyS5 (Android 6.0.1) had no landscape mode switching for several month. More precisely, this switching could reappear when restarting the phone, but it did not stay for long (a few minutes to several hours).
Recently, I wanted to install a compass application, and I discovered that I had also to restart the phone in order to have the compass working.
Thus now I suspect a hardware problem in the positionning or the gyroscopic system.
Is there a way to confirm this diagnostic ?

The switch is lit, which means, I expect that rotation is on. Also, in the Display panel the "Screen Rotation" option is On.

Yes, it is On

 

There is no "auto" option. The only option in the Screen Rotation section of the Display panel is the "Smart Rotation" option, and the On/Off switch.

Sorry I had not understood that you were still in the status bar
I have not exactly the same status bar layout (see photo, sorry in french) , but there is also a tuning line at the bottom with an "auto" box at the right and it is ticked.

 

I have not done all the tuning (it was raining for the outside tuning) but I have done part of it and the GPS seems to work properly. It is the display rotation which does not work. Yesterday it was OK and this morning it does not work.

Hey
How do I safely clear the cache partition ?

 

Samsung Galaxy S5 (SM-G900M) Android 6.0.1

 

OK. I hate those special startups, i had to do it 4 times before succeeding. But once the cache partition wiped and the phone restarted, the screen rotation still does not work .
Note that the GPS Status application has an option "Sensors test". When choosen it displays a list of sensors with after a few seconds a green (OK) or red mark (not OK).
The GPS, light, Magnetic field, pressure, are green = OK
The accelerometer, the gravity, the gyroscope, the linear acceleration, the orientation, the step meter are red.
When clicked the gyroscope line displays a message "The gyroscope is maybe in error. Try to move the phone".
But no movement can change this status. It is the same for other sensors with red status.
I almost believe that there is a hardware problem in these sensors.

I did it. Several taps harder and harder did not change anything.
Well I suppose we have went around the issue.
Thank you to all of you who have helped me trying to solve the problem.
I will live without screen rotation for a while. When I cannot stand it anymore, I buy another phone .
