On Android 15 (Pixel 8), Google has tightened background and accessibility permissions, which can stop Autofill using Accessibility from working properly. If you’re using apps like GB Instagram or other modified apps, they sometimes conflict with accessibility services or trigger Android’s security restrictions. Try this: Go to Settings > Accessibility > Installed Apps and fully disable, then re-enable the autofill service. Check Settings > Security & Privacy > More security settings > Autofill service and confirm the correct app is selected. Make sure battery optimization is turned off for the autofill app. If you have GB Instagram installed, test after temporarily uninstalling or disabling it to see if it’s causing the conflict. Android 15 has stricter protections, so some unofficial apps can interfere with system-level services.
