Do not click on “Exit” if you do not have an intention to exit your wallet account. If you click on ‘Exit’, you will be signed out of your account and will have to re-enter your original passphrase in the “Restore Wallet” option upon the next opened session. If you simply want to exit the app, just click on your Smartphone’s ‘Home’ button and it will exit the app. This is entirely safe to do because whenever you open the application, a PIN Code is asked. Only you know the PIN Code. Therefore, without the PIN Code, whoever is trying to access your wallet will be incapable of doing so.
