Text grabber not working with iOS 7.0.6 on iPhone5

hello, I'm Neil from India, I purchased text grabber on 4th of march 2014, however I'm not happy with the result that I'm getting from this app. I'm getting an error [failed to auto focus] while scanning any document. For your information my screen curtain is off & brightness is set to 50%. are there any steps which I am missing? am I supposed to make any changes in settings or anywhere else? Kindly guide me for the same. any help will be appreciated. Thanks in advance


#1 text grabber

Make sure you enable the recognition languages so the voiceover feature in text grabber will work.

#2 re text grabber

yes, I have already enabled that option. Sometimes it works, most of the times it says, fail to autofocus.
