Samsung has been under pressure recently, as Galaxy S4 unit sales haven't been meeting lofty expectations. The South Korean company has said that it shipped 10 million units in the first month, which, while impressive, was still short of its internal forecasts. Competition on the high end is intensifying, while carriers have also been tightening upgrade policies.

Broadcom (NASDAQ: BRCM) and Qualcomm (QCOM 1.46%) are two companies who were hoping to cash in on the Galaxy S4. Broadcom provides the Wi-Fi, NFC, and GPS chips. Qualcomm sources the baseband modem, power management, and processor in many variants.

In the video below, Fool contributor Evan Niu, CFA, discusses why these two companies may have limited upside from the Galaxy S4.
