All of this information, including pictures of the front panel, were provided by tipster @upleaks. Now the same source claims that the Sony ‘Lavender’ will in fact be known as the “Sony Xperia C5 Ultra”. @upleaks was spot on with his leaks on the Xperia C4, so there is a good chance that this info is correct.
There were numerous rumours over the last few days talking about this handset being called the Xperia T4 Ultra, but this was unlikely from our view (hence no post). Recent Sony H2 releases have an odd number tag, so this year it should have a ‘5’ to denote it is a H2 device. Even-numbered releases are for the first half the year. The Xperia Z3+ bucked that trend, but we understand that was a one-off, given the importance of where the new flagship was positioned.
