Hi!
I have worked on a little vibration script that change the vibration level
Right now you can only choose between soft (S) hard (H) default (D) vibration

Put it in /home/user/MyDocs then in terminal write
sh /home/user/MyDocs/vibration.sh


You must restart the device
Big Y to accept reboot or reboot manually
