- Check the battery status.
- Check your total outgoing call duration setting the day from which the counter starts.
- NOTE #1: the application doesn't store any data and it only uses android call logs to count the call duration. Due to android call logs limitation it will count only available call logs (i.e. around 500 latest call logs)
- NOTE #2: the application needs android.permission.READ_CONTACTS permission to read the call logs.
