Sony to go metal with the Xperia Z4, embed touch fingerprint sensor in the power key

Word from the grapevine is that the Sony Xperia Z4 will feature not only a metal chassis, which we saw in the leaked frame comparison with the Z3 not long ago, but in fact an all-metal body, probably akin to the Huawei P8 that was just announced yesterday. Now, whether that means Sony will do away with the glass rear it pioneered for the Z-line, or do something similar to the Galaxy S6, remains to be seen, but it's the other nugget of info in this latest leak that caught our attention.

The Xperia Z4 is now claimed to introduce a fingerprint scanner, which won't be a complete surprise for a 2015 flagship, of course. The placement of the sensor is said to be unorthodox, though - embedded in the power key. Such a placement would be perfect, if Sony can pull it off, as you want have to stretch your thumb or another digit all the way underneath the display just to unlock your handset or authorize payment, risking to drop it if your mind is not into it. 

There is already a phone with a touch finger scanner in the power/lock key - the Saygus V-Squared, but how will Sony manage to embed a finger-scanning tech of its own on the side of a thin chassis, is anyone's guess, if this speculation pans out, that is. The Z4 is expected to be announced in September, likely around the IFA Expo, while Sony might grace us with an upgraded Z3 Neo in the meantime, said to be revealed on April 20th.

I wonder if Sony will be using Qualcomms new acoustic ultrasonic finger print reader. Its suppose to capture the finger print even if you don't physically touch the device.

I'm not gonna be surprised if Sony pull this off. They were able to have the phone thin with ip certification without protruding camera. No flaps on usb in m4 aqua.

And sony had what? They have been falling and owning a miserable 3-4% of android marketshare. Heck even in Japan they aint doing well.

Samsung still outsold Sony, LG, Lenovo, Huawei, HTC, and Xiaomi combined last year. So yeah, even in their weakest year they're still utterly dominating everyone else. In other words, the chances of Sony, LG, or any other Android OEM overtaking Samsung this year are basically zero. So yeah, LOL! For the record, I do wish there was an Android manufacturer that could actually pressure Samsung, because complacency is the death of innovation and if they only see Apple as their competition then that isn't a world that sounds too promising.

Same can be said about apple, funny that you didn't mention it. Even though I don't like their way of marketing, but I have to say their sale figures are huge.

Umm, all the other OEMs combined do out sell Samsung. You do know that close to 300 million Android smart phones shipped last quarter. Samsung sold around 75 million smart phones which still makes them the biggest, but all the Android OEMs combined out sell everyone.

Yes, but they'll follow up with 6 quarters of record profitability after the S6.

Actually, think about it another way! All phones released in early 2015, will pretty much be outdated! That is the way with tech 6 months on you are pretty much a dinosaur! Should also make a great Xmas buy!

I don't think so because the power key on Z3 is almost as thick as the Z3 body and at 2.8mm i'm sure Synaptics VFS6170 can be incorporated into the power key.

It could be Qualcomms ultrasonic 3D finger print scanner. You can even have food stuck to your fingers and it will still read your finger print.

But I assume that the Synaptics VFS6170 is a swipe sensor, they are calling it a "slide". Their competitor Fingerprint Cards has a touch type sensor for the side of smartphones, called FPC1145 as I mentioned in my comment below: "Besides its core functions as a touch fingerprint sensor, FPC1145 can also host other functions normally using dedicated buttons on the side of the phone, such as a power button or a volume control button. As with all touch fingerprint sensors from FPC, FPC1145 provides leading biometric performance and full 360 degrees rotation support. FPC1145 will be ready for mass production during Q2 2015. During the Mobile World Congress in Barcelona, FPC will showcase a reference implementation of FPC1145 integrated in a smartphone as a side button."

Why hope it's false? I think they won't be able to do it, but I hope they'll prove me wrong! :)

No way! That would be perfect!

Probably Sony will use a fingerprint scanner FPC1145 from a Swedish company Fingerprint Cards. The same company who implemented one touch 360-degree sensors in Huawei Ascend Mate 7 and Oppo N3.

Who cares. At least it would be unique and not a copy and paste job from Apple, Samsung, and HTC. IF they could pull it off it would be awesome as the power button easily rests on the thumb while holding the phone.

Finally, would be good if they ditched that glass that was prone to breaking. The Saygus phone however, has a slide style fingerprint reader, not on the power button but is on the side. Cheers.

Z phones are very durable..not to mention how elegant the glass looked. We'll see how the all metal looks, though.

Just search about FPC1145 from a Swedish company Fingerprint Cards. They already have it in mass production.

I do not know if this rumor is true or not but at 2.8mm thin the VFS6170 can be incorporated into the side, volume rocker button or power key.

Davidroid. If you saw Qualcomms 3D ultrasonic finger print scanner. Then you would feel stupid with the comment that you made. Because Qualcomms method is using sound to capture your print.

They would have to change the design of the power button. Any design change is appreciated:)! Omnibalance needs something fresh and new. My Z1 hasn't exactly been blown away by newer phones.
