Before the Xperia Z5 or the H2 phones are unveiled, Sony is set to announce the Xperia C5 Ultra. This is the first time we're hearing about the new smartphone but we have some hint about its existence. Thanks to a user guide that recently surfaced, giving us an idea that the Xperia C4 now has a followup. Well, that's a quick one considering the C4 was only announced last month. Others are saying this could be the Sony Lavender but we're taking this with a pinch of salt.
