In addition to its entry-level Fonepad, Asustek Computer is set to launch a new smartphone featuring Intel Atom Z2580 processor (Clover Trail+), targeting the mainstream market segment in June at the earliest, according to sources from the upstream supply chain.

The smartphone is expected to adopt a 5- to 5.5-inch display, similar to that of Lenovo's K900 smartphone, which also uses the Atom Z2580 and will be available in China in April, the sources said.

Meanwhile, Asustek's second-generation Nexus 7 is expected to appear in May with enhanced specifications and a price of US$249 to challenge its 7- to 8-inch competitors including the Apple iPad mini, the sources added.
