Finally I have found a new way of downloading YouTube videos directly on your mobile. No software is needed for downloading YouTube videos. Many times such situation appears when we hardly needs to download a video on our mobile but can't download it.
Here is the trick to download YouTube Videos:

1. Go to the URL of the video you want to download:

2. Replace "m." from the url with "ss".

3. Press the O.K button.

4. You will see the available formats for downloading YouTube video. Select the format which is compatible with your mobile and download it.
That's it...Download the video and watch...
