Had the same problem of course and tracked it back to DriveSafe.ly. (Removed each app and restarted and ended up by process of elimination)
Also, requested a refund from the DriveSafe.ly people three times.
The first email asked me when and what was happening when the problem occured.
The second asked me if I could have gotten a "bad build" and please try reinstalling the app.
The third email stated that I should absolutely try reinstalling the app even though I was very dissatisfied with the app.
Today after requesting a refund for the fourth time, i got an email saying:
I fail to see where a refund was refused. Did you follow the steps
that were suggested by the tech team? The last communication I could
find was a request to reinstall the application.
Let us know if you have any further questions, we'll be glad to help.
