Cyber-shot DSC-H9 has major design flaws

I have an 18 month old Sony Cyber-shot DSC-H9. I also called the factory within 30 days of purchase explaining to a speaker of English their design flaws and asking for some way to correct them. No response. 1) The camera takes a picture of the adaptor ring edges, so all four picture corners show interference. 2) The lens adapter/hood sits in front of the flash. All flash pictures have a half moon shadow through the middle of them. The only way to avoid this is to unscrew the adaptor at night. 3) Flash pictures have grainy reds, greens, and blues throughout. The camera is designed for very small hands. My thumb base covers the sensitive control button and changes flash settings. This is definitely a small hands camera.
