Change (NEXT or PREV) the songs on the iDevice using volume keys (JAILBROKEN)

If you have a jailbroken iDevice(iPhone, iPad or iPod) then you can use the volume keys to change the songs while playing. You can either Next the playing song or Prev(Previous) the playing song. You just need a simple Cydia tweak known as 'Activator' to do so!

Activator is a simple but very important tweak developed by Ryan Petrich used for defining many tasks for simple gestures. It can be downloaded by adding this repo:

After you've installed this tweak, following process commences:

1. Go to Settings > Activator.
   
   
   


2. Click on 'At Lock Screen'.
   


3. Scroll down to VOLUME BUTTONS section then tap 'Up Short Hold'.
   


4. A new menu appears, tap on 'Next Track'. This will allow to play the next track while playing the music.
   

NOTE: 

• The above process will work only on the locked iDevices. 
• Similar process can be carried out to play the previous track. Just tap on 'Down Short Hold' instead of 'Up Short Hold' and 'Previous Track' instead of 'Next Track'.
• This trick will only work on JAILBROKEN devices.
