Common Delta - Game Emulator App Problems and Troubleshooting Steps

Android, iOS, or macOS operating system users may encounter a problem where an app will display a black screen for a few seconds before crashing, with or without an error message. However, there are a few methods you can try to fix this issue:

Sometimes, this problem may be caused by a temporary loading issue. To fix this, go to the recent applications menu on your phone, usually accessed by the first left button, and close the app that is experiencing the issue. Then, re-open the app.
If that doesn't work, try doing a hard reboot of your iPhone, iPad, Mac or Android device by simultaneously pressing and holding the "Home" and "Power" buttons for up to 10 seconds, then release them and hold the "Power" button until the screen turns on. After that, try opening the app again.
If none of the above solutions work, another option is to wait for the phone battery to drain and turn off automatically. After that, charge the phone and turn it on and try opening the app again.
If the problem persists, you may need to uninstall and re-install the app. Re-installing the app will restore all settings.
If the app still does not work, you can try installing older versions of the app.

Please note that, Good luck or re-installation may not always work and it may vary based on the app, phone and the problem.
