Soo… just open capture.pcap in Wireshark and selecting File -> Export Objects -> HTTP… lists the files the phone exchanged over HTTP:

Wireshark HTTP object export list

One of the exported objects is named get_flag, and its body is a hex string:

56475372666732367b4c726c6c6c6c5f6630796933715f6a34786768616c345f7a33613461347a217d

From Hex turns it into VGSrfg26{Lrllll_f0yi3q_j4xghal4_z3a4a4z!}. A ROT13 brute force confirms it, at key 13:
