Resolve Issue With Virtual Keyboard Not Appearing on the Shift4 One App

What is causing this Issue?

On standalone PAX devices, the on-screen keyboard may not appear when attempting a manual entry transaction in the Shift4 One app. This prevents you from entering the card number manually.

Internal:
This occurs because the Shift4 One app relies on the Shift4 Lite/P2PE applications to generate and display the on-screen keyboard. If the Shift4 Lite/P2PE app does not have permission to display over other apps, the keyboard cannot appear within the Shift4 One app.

How do I resolve this Issue?

To resolve this issue, you must enable the “Display over other apps” permission for the Shift4 app on the device.

To enable the permission:

1. From the main menu of the device, tap Settings.
   
2. In Settings, select Apps & notifications.
   
3. Select Shift4.
   • If you do not see it immediately, tap SEE ALL {number} APPS and scroll through the list until you find Shift4.
     
4. After selecting the Shift4 app, tap Advanced at the bottom to expand additional options.
   
5. Tap Display over other apps.
   
6. Toggle Allow display over other apps to ON.
   

The toggle will change from grey to green, and the indicator dot will move to the right.

Test a Manual Entry Transaction

1. Navigate back to the Shift4 One app.
2. Attempt a manual entry transaction.
3. When prompted to enter the card number, tap the card number field.

The on-screen keyboard should now appear, allowing you to manually enter the card information successfully.
