Once Ten has his hands on the phone, he begins immediately examining it. He flips it over in his hands, looking over every single part of it and taking in the details. When Garrot chimes in that he'll have to give it back, well.

It takes all his self control not to eat the phone.

He finally flips the screen-side back to facing him and then he starts gooshing his fingers against the screen.

Nothing happens.

He tries once, twice, again, and again. In the end, there's no result whatsoever. All ten of his eyes squint at the screen before they drift slowly up to Garrot. The betrayal is clear in his eyes. If Garrot knows anything about how capacitive touchscreens work (rather than resistive), he'll have a pretty solid suspicion to run off of.
