I am trying out the app and if it works properly I will get the racerender software. So far it seems like the perfect app I was looking for but I have 1 issue I can't seem to overcome. I have a samsung galaxy s5 phone. I went into camera settings AND I think I turned off autofocus, but when using track addict, it keeps on trying to focus the whole time video is being recorded. I didn't see a setting in the app to disable that either. Am I missing something? Thanks.
