Soft Touch Vibration Changed After Miui 7 Update

Feb 26, 2016
Hi everyone!
I bought a used Mi3 some week ago with MIUI 6 on board. I decided to update to last MIUI 7 ROM available, but after the update I noticed a deep change in soft touch vibration for Menu, Home and Back buttons. On MIUI 6 there was a really good feedback (like "toc" sound), now on MIUI 7 the feedback changed with a "bzzz" feedback. I also tried to set vibration intensity in Settings/Sound on Light, Medium or Strong, but no success. Is there any way to turn back the vibration feedback to the V6 one? Or is it a definitive change after the V7 update?
Thank You and sorry for bad english (I'm italian)
