How do yall get clear pics

No matter what I do it's to bright, flash no flash, close, far. I dont want anyone thinking I'm crazy but I believe I'm starting to see a little something at 9 days late. But I know yall cannot see it. How can I take better pics so it doesnt blurt out the extremely faint line I'm seeing so noone thinks I'm crazy. I have an awesome camera on my phone I dont understand lol samsung galaxy note 10 plus
