Waterproof-ness

[SevenD2]

How waterproof is the phone?

Can the touch screen be used underwater?
I know it can be used right after taking it out of water, but what about under the water?

Also can buttons be pressed in the water?
If not, will the phone be damaged if a water drop falls into the button space when pressed?

As long as all the flaps (USB/audio jack/SIM/microSD) are closed the phone is completely waterproof. It can withstand up to 30 minutes at 1m depth and water jets (shower/rain/...).

The touchscreen cannot be used under water, this is impossible with capacitive touchscreens.

All buttons can be used under water.

Actually I think screens are OK when fully immersed. It's when they have drops of water all over they have problems. This may vary depending on the touch panel in use but it's not impossible.

I saw some info "forgot where I found it" that the touchscreen of the Xperia Z/ZL supports pressure detection so if this is the case it might be possible to use it underwater. Will post the link soon when I find it.

Capacitive screens use conduction for sensing the touches so not sure about this.

Edit!

Just wondering what's Throw?

The pressure sensor is not in the display but an actual air pressure sensor. Can be used to calculate at what height above sea level you are.

Capacitive displays work with electrical charges. There run tiny tiny wires over the display that detect when they are interconnected, which happens when you touch them. The problem is that when you use it when it is completely immersed, everything appears to be connected to everything. With drops of water it's possible to filter them out somehow (I don't know the details on this), but while fully immersed it's impossible to distinguish between what parts are being touched by water and what parts by skin accurately enough to provide touch input.

Throw is one of the marketing terms for Sony's DLNA stuff. You can "throw" images and video's to your TV and other devices over DLNA.

Ok... And I thought it was a pressure sensor on the screen I was planning on porting the python mypaint would have been great if the phone has pressure sensitivity.

Actually, pressure sensitivity on tablets and phablets (like the Galaxy Note series) is done with pressure sensors in the pen, not in the display. The display has some sort of electromagnetic resonance that (through induction) powers the pen and allows the pen to transmit back what amount of pressure is being applied.

One of the other ways that allows (limited) pressure sensitivity is by using a resistive display, and that isn't possible with a glass display surface. In addition to that, it is quite crappy.

I saw a video on youtube ( Can't remember by who, maybe Clove?) where they submerged the phone under water and the guy tried taking photos with the camera, the touch doesn't work at all under water. Makes sense with the explanations above, phone is meant to survive if it takes a dunk really
