Auto-rotate not working properly

[HelenH2]

Galaxy Tab A7 Lite SM-225

I like to use my tablet in landscape orientation.  I’ve selected auto-rotate, then turned the tablet into the landscape position, then locked it there.  The problem is it reverts to portrait within 15 minutes or so.  It’s really annoying as I want to use all apps in the landscape position. 

Any help would be great.

Thanks for reading

@HelenH2: Does the tablet revert to Portrait when you open a particular app, or navigate to a certain screen? Not all applications and features support Landscape mode (even the Home screen of your Galaxy A7 tablet defaults to Portrait unless Landscape mode is toggled on in the settings) so I just wanted to manage your expectations in that regard.

I have a similar problem. The tablet refuses to lock into Portrait mode when Autorotate is turned off. It doesn't matter what app I'm using. If I accidentally tilt the tablet too far, it switches to landscape mode and requires futzing around to get it back to portrait. What can I do about this? Do I need to do a factory reset?
