Welcome to Android Central.
We will need more information and replies from you in order to help.
What device do you have?
When you say it flickers, please describe the flickering so that we are able to imagine what is going on. Is it a constant flicker like it is strobing intentionally, is random with no pattern, does it mater if you're moving, like a short circuit, please describe?
What happens if you do it in safe mode?
If it worked Okay last night and it only happened this morning, will it do it if you turn it on right now?
Is this the first time this has happened? If not please tell us what happened last time?
please include anything else that might help us help you. To receive notifications when others reply to your thread and to leave comments of your own please take a minute to create an account. It will help you communicate and get help. This link will guide you through how to do that...
