I'm pretty sure it's an Android phone, due to the capacitive buttons on the bottom. From another point in the episode, it showed a "<", a home, and the multitasking button shown in the picture above.
What I have to go on:
Super thin bezel (probably a newer phone)
The episode took place in Argentina, but it's a tv show, so that may not mean anything
Capacitive, not onscreen buttons, in the arrangement, "back, home, multitask"
