Samsung (SSNLF.PK) is set to announce Galaxy S4 shipments have topped 20M, reports Korean news site iNews24. If true, that would mean the milestone was reached a little over 2 months after sales began, and about 5 weeks after shipments crossed 10M. For reference, it took 100 days for Galaxy S III shipments to top 20M. Though shipments could be notably higher than end-user sales if channel inventory is building up, the report (if accurate) might soothe fears of weak demand (spurred by multiple build order cut reports) a little bit. Suppliers with strong exposure: QCOM, BRCM, SYNA, RFMD, ANAD, OLED.
