Hello,i have just bought a GSmart Roma R2 android. I managed to adjust the settings to my liking,but can't turn off the vibration! I am not talking about the vibrations when i touch the screen,I managed to turn those off myself,but when touching the three home buttons,it makes the most annoying vibrations and it really ticks me off! :/ I don't have a Settings -> Sound option.. Please help,I am desperate to turn this off!
