Overlay icons are not supported on Android Go devices
Android Go devices, optimized for lower-end hardware, lack overlay icons due to intentional design constraints. The "Display over other apps" permission, responsible for these icons, is often disabled on Android Go phones to prioritize performance and conserve resources.
Examples of Android Go phones:
- Nokia c21
- Motorola e20
- Motorola E22I
- Nokia 1 Plus
- Nokia 1.4
- Vivo Y15s
- Vivo Y01
