Hola buenos días, se me instaló no se si es una aplicación, porque en la lista de aplicaciones no está, se llama CallerCard, no puedo contestar llamas cuando lo hacen desde el WhattApp, desde ya muchas gracias por su respuestas
This kind of thing can also be part of another app you may have installed, like a 3rd party launcher, file manager, "antivirus" app, "memory booster" app, or something else. Do you have anything like that installed?
Restart your phone in Safe Mode If the issue disappears, it confirms it’s a third-party app Uninstall the culprit
Once you find the app causing it, remove it
This is not part of Android itself — it’s coming from another app and that's why it affects WhatsApp calls.
