The report suggested the impact of the US ban on Huawei hasn't yet impacted the smartphone market, will likely show up in 3Q19 data.

The smartphone downturn has gained momentum in 1H19. Global shipments decreased to 331.2 million units in 2Q19, down 3.6% YoY. This means the decline has been ongoing since 3Q17, predating the trade war by several quarters.

The slowdown in shipments in 2Q19 was widespread, with only four brands (Samsung Electronics, Huawei, OPPO and TCL Alcatel) out of the top ten achieving YoY growth during the quarter.

Jusy Hong, research and analysis director at IHS, said the Huawei ban wasn't in effect for the whole quarter, since it was only announced on May 15. As a result, the impact of the ban on Huawei was limited. The company shipped 58.7 million smartphones in 2Q19 globally, down less than 1% from 59.1 million units in 1Q19 and up 8% from the 2Q18. Huawei's market share rose to 18% in 2Q19, up 2% YoY.
