Please How to disable the screen overlay?

Hi @Merry1, welcome to our forum!
Your question has been translated to English as this is an international forum.
If you receive a message regarding that you should turn off screen overlay in your device, you have a installed third party application that is not compatible with this Android feature.
When do you get this message? If you receive it when trying to give permissions to an application you can restart your device in safe mode and give the application(s) the correct permissions and then just restart your device when you are done.
I hope that helps!
Thank you so much, I already solved the problem

Let me know if there is anything else I may assist you with and have a great weekend!
