 This setting gives the ability to choose between the controller types _Xbox, Xbox 360, PlayStation 1/2/3, PlayStation 4, PlayStation 5, Switch Pro_ and _SNES_. Doing so alters the help icons and help text as well as the icons and text for the input device configurator. The setting is only cosmetic and does not change the controller behavior or the controller button mappings.
 
+**Touch overlay size** _(Android only)_
+
+If the touch input overlay has been enabled, then this setting makes it possible to select between a _medium, large_ or _small_ overlay size.
+
+**Touch overlay fade-out time** _(Android only)_
+
+How long, in seconds, to display the overlay before fading it. Tapping anywhere on the screen will bring back the overlay if it's been faded out.
+
+**Enable touch overlay** _(Android only)_
+
+The touch overlay applies a layer of virtual buttons on top of the ES-DE window. This makes it possible to use the application on devices that lack physical buttons, such as a mobile phone or tablet. Be careful to not accidentally disable this setting as you may lock yourself out of the application. If you do that, you'll need to temporarily plug in a controller or keyboard to enable the setting again, or you could clear the ES-DE storage in the Android App settings which will force the configurator to run on next startup.

 **Only accept input from first controller**
 
 If enabling this option, only the first controller detected during startup will send its input to ES-DE (the keyboard input is unaffected by this setting and will be enabled regardless). This is a good way to limit potential chaos with multiple persons fighting over which games to play. Note that disconnecting and reconnecting controllers while ES-DE is running may change what is considered the first controller. This setting does not affect the emulators in any way, it's only applied to ES-DE. Another issue is that some wireless controllers have buggy drivers and will register as two devices, meaning all button presses will be registered twice inside ES-DE. Using this option is one solution to the problem, although it's also possible to blacklist the extra controller entry, as described [here](INSTALL-DEV.md#adding-custom-controller-profiles).
