With Xperia Z4 (Z3+), Sony cracks the case of operating the screen on a wet phone
Waterproof phones are the greatest invention since Ziplock bags, and some, like Sony, even managed to make them thin and slender - a far cry from the fat rugged slabs of yesteryear. There is one annoying issue with a phone that can get wet deeper and longer than others, though, namely the chaotic operation of a touchscreen with water droplets on it. Once the finger slides over a wet portion of the screen, the laws of physics change dramatically, and the touch sensitivity goes all over the place, either failing to register something at all, or responding far from what you intended to do.

No more, said Sony with its newest Xperia Z4 (Z3+) flagship, and developed a touchscreen algorithm specifically geared towards operating the screen with wet hands. The welcome invention has something to do with updated touch drivers and sensitivity adjustments, but in any case, the resulting responsiveness is pretty great, as you can see for yourself in the brief demo below - the finger taps and swipes get tracked almost precisely where they land, regardless of the sprinkled touchscreen of the Xperia Z4. Nice one, Sony.

And where did you read in this comment section any negative comment about this new technology? But i guess you are so insecure that you had to bring up Apple, Samsung and their fans.

He's probably just predicting the possibility. I approve his thoughts though as Apple and Samsung highlights their software features. Sony is just lazy to promote, relying on their "big" brand name to sell. When there are many surprising features hidden in their UI.

Well the thing is Maherk, that Sony never promotes properly their features... If I were to ask you, who implemented "Air Touching" in android, you would probably mention Samsung GS4... But Sony did it first, albeit less useful, with the Xperia Sola. Wet Tracking is not new and not exclusive to Sony, but they have implemented it since the Xperia Active (if I am not mistaken), my Acro S had it and it was good... And my Z3 Compact is even better at it... So yeah this is a great tech and a Must have for waterproof phones, but Samsung and the other popular guys haven't implemented yet... But when they do people will think they did it first.

I can operate my z3tc with even more water on it. With the z2t and the z3 its a bit worse but still doable. I thought sony had changed it earlier

Yes, wet tracking works great on my Z3 Compact as well. Even my Acro S did good... But hopefully we will see something new here... Sony always under promote their features...

Yes that's true but they really improved it on their z3 line. I can use WhatsApp in the shower.

It is Samsung who are out of touch on pricing in the UK. They may have upped the quality but they are not a premium brand. Most people are holding off buying the S6 or S6 Edge because they know the price will drop like a stone a year from now. The latest Galaxy at S5 prices, now that would sell like hot cakes.
