Generally it is great when using my tablet or phone that as I rotate it apps move to stay upright. But sometimes its not! Like when I’m reading a book and move my head away from the sun. Suddenly the text is sideways!

Sure, you can turn rotation off for everything. But that’s a bit nuclear!

The good news is that you can stop this happening on an app-by-app basis on Android. A new app called Rotation Manager lets you choose which apps stay locked to portrait or landscape. The permissions might seem a little intrusive but I think it is worth it for the convenience.
