Hey friends!!!
Here I am sharing my own and true experience.
This vidmate application shows error while downloading this makes me so annoying!!
Many times I downloaded mp4 audio files through vidmate but it is not playing!!
Many times I played song but it shows error , youtube is much better the vidmate.
We can download offline songs in the youtube but we can not do the same thing in the vidmate application.
I recommend that do not use vidmate application.
