I just put my 0.4mm Invisible Shield tempered glass on my 6S, and 3D touch works flawlessly.
I'm not saying this applies, but my wife's Otterbox Defender for the 6 works just fine on her 6S.I am more concerned with my battery case than the screen protector. Worried that the thickness/plastic protector may interfere. I grabbed a tempered glass protector and a leather case from Apple earlier just in case.
