Is there a way to mirror Android screen permanently?

  • Maybe you already have an app that does it (I didn't found, searched a lot); maybe you can give me Java code that does this, so I can compile it and use. – Monsieur Pierre Doune Sep 11 '19 at 23:34
  • The only thing I've found is `Force RTL layout` function in Android, but it doesn't mirrors the text and works really bad with all apps. – Monsieur Pierre Doune Sep 11 '19 at 23:39

    Beyond the obvious entertainment value, is there any other practical use case for this behavior which would make it harder for the individual to identify icons/text on their screen and/or naviagate? – Morrison Chang Sep 12 '19 at 00:09
  • You need rooted phone to do this – Farrukh Nabiyev Sep 12 '19 at 05:50
  • @MorrisonChang it's not entertainment for me, this layout is more natural for me as for a left-hander; also I want to practice my mirror reading skill. – Monsieur Pierre Doune Sep 12 '19 at 08:32
  • @MorrisonChang it is not an trolling app to prank my friends, if you this about. – Monsieur Pierre Doune Sep 12 '19 at 08:35
  • If root isn't an option, you might be able to use the `MediaProjection` API to capture the screen and flip it. For some direction see: [Take a screenshot using MediaProjection](https://stackoverflow.com/q/26545970/295004). While there are a number of open source demo projects, the hard part would be the flipping or transform which would probably involve OpenGL ES. Good luck. – Morrison Chang Sep 12 '19 at 16:55
