FAQ - Frequently Asked Questions


How do I set BIG Launcher as the default launcher?

When you press the Home button after installing, you will be offered to choose a default launcher from all available. Make sure you select the 'Use default' or ‘Always’ option. If this menu doesn’t appear, you have to do it manually - press the Menu button, go to System settings » Apps » Default apps » Home screen and choose “BIG Launcher”.

How can I revert back to my old launcher?

You can reset the default launcher setting in the Preferences. If this doesn't work, press the Menu button, go to System settings » Apps » Default apps » Home screen.

I’ve purchased BIG Launcher in the past and now I have only the free version. How to restore my license?

Send us your order number (from the email receipt you’ve received upon purchasing) and your email address used for purchasing and we will help you to restore your license for free for all BIG Apps Suite apps.

Why was BIG Launcher divided into 3 separate apps?

On March 9th, 2019, a new Permissions Policy was introduced, which applies to all Google Play Store apps. Since then, BIG Launcher (as a launcher) couldn’t access SMS messages and phone calls anymore, as these permissions were allowed only for the apps which have them as their primary functionality - not launchers. In order to comply with this policy, corresponding features were removed from the BIG Launcher app and put into separate apps - BIG Phone and BIG SMS. You have to download and install them separately.

How do I set up multiple screens in BIG Launcher?

You can set up multiple screens in the Preferences menu. You have to link your newly created screens to the existing buttons, otherwise, you won't be able to access them. Or you can turn on the option to swipe between screens in the Preferences menu. Please read the User Manual for more details.

How do I delete a message/contact/call log item?

Due to security reasons, deleting is disabled by default. You can enable the deleting of the particular items in the corresponding sections of the Preferences. Please read the User Manual for more details.

There is no ring sound on an incoming call.

Go to the Preferences » Phone and enable “Fix: no ringtone sound” option. If this doesn’t help, write to us at contact@biglauncher.com.

SMS messages aren’t received at all.

Go to the Preferences » Messages and enable “Fix: alternative SMS receiver” option. If this doesn’t help, write to us at contact@biglauncher.com.

How to turn on the button blinking for other apps like Whatsapp, Gmail, Facebook Messanger, etc.?

In the following screen, enable the Notification access for BIG Launcher.

How to set up or turn off the incoming SMS notification sound?
