I've come across an interesting issue with my 620. Yesterday when it got bit warmer than normal, I found that the back, Windows and search buttons had lost their haptic feedback, despite the vibration option being turned on. Power cycling seemed to clear it and it happened again today. The vibration itself is fine as I could receive vibrating notifications with no problem.
Has anyone else come across something similar? (on other Lumias, not just the 620 :smile
