Specific Remove flare please

[dizzymare25]

Hi, I never get pic of my two kids together. There's something wrong with my camera phone, whenever I take a photo with the flash there's a semicircular artefact on the image. If anyone can help to remove it/ optimise the image I'd be really grateful. Thanks in advance.

that annoying flash artifact might just be a piece of dust or grease on the lens.

Thank you to everybody who has replied. I'm so grateful for your efforts. It's so lovely to have a photo that's worth of being printed and put on the wall! I don't know what's up with my camera....I have a glass back on my phone and it's been changed since the problem started so I guess it's a problem with the lens itself. I can't get to it to clean it as it's behind the glass. I think I'm going to have to put up with it until I upgrade! Thanks again everyone I'm really so grateful xxx
