That's according to  Digitimes which says business at MediaTek and LCD driver IC solution provider, FocalTech Systems started to pick up in the second quarter of 2018.

MediaTek saw its March revenues start to register sequential growth, with the revenues surging 58.2 percent sequentially $688.1 million, while FocalTech's March revenues climbed to a record high.

MediaTek and FocalTech are among the chip firms involved in the supply chain of first-tier China-based smartphone companies including Huawei, Oppo, Vivo and Xiaomi, which have stepped up their pace of orders prior to new product releases.

As the four smartphone vendors' combined share of China's smartphone market has exceeded 70 percent, their chip providers are expected to outperform those which fail to obtain orders from the four major China-based smartphone companies during 2018.

It does not seem like the good times will last as many of the market watchers are less optimistic about China's smartphone market outlook for 2018.

Canalys claims that China's smartphone market suffered its first annual decline in unit shipments during 2017 falling 27 percent from a year earlier to 81.87 million units in the first quarter of 2018.
