The Murder in the Middle East - S10-E19
Continuity mistake: In all shots of Cam talking on her phone to Arastoo after the first, what's on the bottom of the phone is different to the first. Later, when she has the phone is on the table, what was on the bottom in the later shots is at the top of the phone, suggesting at some point she started talking on it upside down.
