The Ascend D quad, Huawei's answer to quad-core smartphones such as HTC's One X and LG's Optimus 4X HD, will not start production until at least August, according to comments from the chief of the company's consumer business group. Posting on the Chinese microblogging site Weibo yesterday, Yu Chengdong revealed that Huawei was experiencing "technical problems" with its ambitious K3V2 system-on-chip. But he noted that the company's R&D division was "stepping up efforts" to get it ready.

The Ascend D quad was announced to much fanfare at MWC earlier this year, with Huawei PR describing it as the "world's fastest smartphone." While benchmarks surfaced in March seeming to back up this bold claim, they really don't mean much if the company can't get the device ready for production on time.
