Android Marshmallow and later introduced "Draw over other apps," allowing certain apps to overlay content on top of others. Common examples include Facebook Messenger chat heads, WhatsApp call screens, or screen-dimming apps like Twilight.

The issue arises when a new app requests permissions (like storage or contacts) while an overlay is active. Android blocks permission changes during overlays for security, triggering the error.

Background apps like Twilight, chat heads, or screen filters often cause interference. Force-stop or disable them briefly:
Many devices prompt you to adjust this directly. If not:


On stock Android: Search "draw" in Settings > Apps > Special app access > Display over other apps. Toggle on for needed apps.


On customized Android (e.g., Samsung, OnePlus): Settings > Apps > Menu (three dots) > "Apps that can appear on top." Enable toggles.
Newer flagships like OnePlus 3/3T or Samsung Galaxy S8 auto-pause overlays, but the error can still pop up. These steps provide a permanent fix for smoother Android performance.
