Sony is expected to unveil a new flagship phone during Mobile World Congress in Barcelona next month; the much-rumoured Sony Xperia XZ Pro.

We've heard a few speculative, promising details about it over the last week or two, including its alleged 4K HDR OLED display, but the latest leak will likely be less well received.

According to a filing with the US communications regulator, the FCC, the next Sony flagship smartphone will come without a headphone jack.

A diagram included in the filing is imprecise in showing the actual connections at the bottom of the handset, but it does hint at a dongle.

It shows an external adapter with, presumably, USB-C power and 3.5mm headphone jack ports, and then a USB-C connector that goes into the bottom centre of the phone.

Bad news for Sony mobile fans who usually gloat at their iPhone and other non-jack smartphone sporting chums.

The same documents also reveal the dimensions of the phone (152.79 x 72.42mm) and confirm that the display will be 5.7-inches, as often rumoured. However, there is little else to glean from the filing.

We'll no doubt see the phone in its full splendour during MWC 2018, which starts at the end of February. - PAY MONTHLY PHONES The Samsung Galaxy S10+ is now available on EE who have been awarded the UK’s best network for the fifth year running. RootMetrics tested the four UK networks and EE was faster and more reliable than all of them, with better data performance. Their network has come a long way since they launched in 2012. Back then they had 11 UK cities covered by 4G. Today they cover most of the UK’s land mass, thanks to 19,000 state-of-the-art 4G sites. They’ve got faster, too – from 50Mbps to a maximum speed of 400Mbps. And they’re soon to experience even greater possibilities with the launch of 5G.
