Front camera takes fuzzy images

[narsimelus]

Hi, 

I'm using Z2 for more than a year. My problem is that the quality of front camera's photos are too bad. Yes, it is only 2.2 mp but my previous phone (Samsung Galaxy S2) was not taking pictures as fuzzy as this one although it was 2.0 mp. I'm not sure about this problems duration. I think it was better last year. Thus, maybe upgrading system or something like this affected on camera software. 

Do you know if there is any way to fix this problem? I want to take nice photos with both cameras. 

Thank you.

Check if there's anything on the camera lens such as dirt, grime or a film.

Thanks to all of you for all your suggestions. Unfortonately, nothing made my front camera photos better. Maybe it's default status. 

Anyway, thanks again.
