Customize Android system settings for individual apps

Sometimes, you may want control over an application's behavior on your Android device. Maybe you want a media player to always load in landscape mode, a music player to use a certain volume, or an application to only use Wifi and not mobile data.

While you can go ahead and make those modifications manually every time you launch the application, it is not comfortable and the likelihood that you are forgetting it sometimes is rather high as well.
Specialized applications come to the rescue. I have reviewed a couple in the past. Smart Rotator sets auto-rotate options for apps, NoRoot Firewall which apps can access the Internet, and Screen Controls the brightness and screen timeout of apps.
App Config Free does all that and then some. It lets you set app-specific settings for the following features:

1. Screen brightness.
2. Screen orientation.
3. Screen timeout.
4. Volume.
5. Mobile Data.
6. Wi-Fi.
7. Bluetooth.

You can use it to turn off all data types so that an app cannot access the Internet, make the screen brighter or darker for an app that you may find to bright or dark, turn on Bluetooth when you load an app that makes use of your Bluetooth keyboard or speakers, or modify the volume for the dialer app or another app using sound to increase or decrease the volume of it.

Best of all, those changes are applied automatically by App Config Free when you start apps that you have created custom profiles for, and reset to their original values once you exit the app again.
The application displays a list of all installed programs on your device on start. To customize an app, simply tap on it. This brings you to the configuration screen which you can use to modify one or multiple of the available features.
Depending on the feature, a simple on or off switch may be displayed here, or a more complex list of options.
Apps with custom options are displayed in bold in the application listing. They can also be accessed with a tap on an icon in the top bar of the application which only lists modified apps.
The free version displays ads in the interface. A paid version is available as well which does away with the advertisement, supports system wide settings, settings for launchers, option to start on boot, and hide the notification icon when no settings are applied.

Verdict

If you find yourself regularly adjusting system settings such as the volume, screen orientation or net connections when you use specific apps on your Android device, you may find App Config useful as it automates those manual processes for you.
