I seems to have issues only with taking still pictures.  8 of 10 it is always blurry...is there a settings to avoid getting this...

What settings are you using

Hello! In the DJI GO App, the second and forth icons in the left menu list are for the camera parameters setting. For the details, please refer to the User Manual which you can download in DJI offical website. Thanks!

make sure there is at least 1.5m between you and the subject (according to OSMO documentation on focal length)
