Many have suspected that Sony wasn't done with its 2013 high-end phones just because the Xperia Z and ZL were shipping. As of today, that's more than just speculation: a once-rumored Xperia A has swung through the FCC for approval as NTT DoCoMo's SO-04E. The filing is unusually detailed for a device that isn't official, showing a 5-inch, 1080p handset that maintains Sony's OmniBalance look while including a removable, 2,300mAh battery that we haven't seen in the Z or ZL. The manual also has the Android phone sharing the Z's 13-megapixel camera, 16GB of built-in storage and LTE, although mum's the word on any upgrade to the Snapdragon S4 Pro. Sony hasn't confirmed what we're seeing, but we may not have long to learn the full story when NTT DoCoMo is revealing its summer mobile lineup on May 15th.
