Asustek Computer's next-generation ZenFone 2, which was originally set to start selling in February 2015, may be delayed to March as related development is behind schedule. However, the smartphone will still be showcased at CES 2015, according to a Chinese-language Apply Daily report citing sources from the upstream supply chain.

Meanwhile, Asustek is also preparing to unveil a high-end ZenFone product designed specifically for taking selfies, but the device is unlikely to debut at CES, as Asustek has recently decided to change its specifications to enhance its competiveness, the report added.
