The home button on Androids is closing my game instead of just pausing it and minimizing. It never used to exit, though. Before, the home button would always call OnApplicationPause(true) and I would have the menu pop up and Time.timescale set to 0. Now, the game just exits.
home button is used for quiting a application so if you will use it to make your game pause sometime it will quit the gam so make your own pause button
I just had this! The answer for me was to remove all the deprecated old sections from the AndroidManifest.xml, then the Home button worked fine and restoring the app from the recent list.
