DW Missed call notification cleaner patch

If prompted patch was not successful. Please try the following steps.

1. Download the file to your phone.
2. Copy it to the directory where the system software. Should be the stock Contacts app in the same directory. Maybe "/system/priv-app/" or "/system/app/".
3. Then change the mode of FILE to 644. (Modify file permissions, so any user can read it)
4. Restart the phone.

Now the system application manager should be able to see "DW Missed calls notification cleaner". You can now try it. When DW Contact attempt to clear the missed call notification, you should see an alert dialog box.
