This may not be in the correct section, but I'd like to share with you guys the truth behind Apple's iPhone 4S's heart of imaging. Not surprisingly surprised, but this might only be an upgraded or modified version of the Arc's camera unit.
And perhaps, the Hybrid IR sensor could be the same technology as the Exmor R sensor. What'd you think?
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.

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
After lil more than 1wk, I still discover a few new things about this amazing phone. Particularly the built in sensors. I read somewhere that S4 is the first smartphone with hygrometer to measure humidity. Cool.
But i have no idea that there's also the magnetometer is there also to measure magetic flux and field strength. I had fun moving it close to electronic equipments and an old phone case with magnetic clasp and see how the reading changes. testing near MRI is of course not rec.
Of course the barometer and thermometer are there too.
Between the two apps: weather signal and weather station, all these sensor readings can be accessed live... amazing.... forget about accessing s health to read sensor...
the only thing iphone got above s4 is the fingerprint reader. But i am quite certain that samsung won't let that by on their next iteration of the galaxy... Maybe they can figure out how to make a pulse reader and pulse oximeter sensor to build into the phone? I think built in body function sensors could be the next big things...
Btw, i am about to enclose my S4 into a watertight case. I imagine the barometer, thermometer and hygrometer will be a little less accurate .
How to read all the sensors data? But not the raw machine data, preferable with human readable interface?

I don't think there's a thermometer on here

I showed the s4 sensor readings on weather station..... my friends thought I was just pulling the local weather numbers off the internet and said their iPhones could do that too... I don't think they completely believe me that the numbers on the s4 were not from internet....
How does the thermometer measure anything but the battery temperature? I figured that the battery temp would overshadow anything else it could measure. Maybe my phone just runs too hot?

I've just encased mine in a watertight lifeproof knockoff. So now these sensors are not as functional. I do see yr point about battery temp and i think weather station actually has a pro ver which try to compensate for even the presence of battery heat. I am fairly certain though that the sensor doesn't just measure your battery temp and can't measure anything else....
Is it using the IMX258? Or is it something newer?
Are all three lenses the same?
First of the lens is the optics. Sensor is the silicon under it, what film was in the old analog days. Both have effect on the outcome.
I have no plans to open the phone but IMX258 looks like to fit within the specifications well. Sony dominates the sensor market so it's very unlikely to find anything else there.
Regarding the optics, as there is are not a typically blue "ZEISS" logo, but yet it's printed so they are somehow involved. I don't believe in manufacturing in Germany as they barely do their own top of the line lenses there anymore. Maybe Zeiss machinery and tools might have been used for creating these lenses, or maybe licensed design etc. Probably no classic radiocative micro-contrast woodoo, but it doesn't matter, (yet it would be fun to hear a story what they actually provide). Whenever Zeiss optics are involved they tend to help providing pleasant image rendering to the human eye, not necessarily a benchmark winner in synthetic sharpness tests.
Todays smartphone/small image sensors are way ahead their larger brothers, I would not bet on an magical jumps in technolog, rest is physics. A physically bigger sensor will help collecting more light, and there for increase low light performance, and possibly also some dynamic range.
These dual sensors RGB+monochrome is of course just some software magic algorithms pushing more contrast into the images. Maybe we see layered sensors soon, like Foveon or even a triple sensors that Red, Blue and Green each get their own. But again, it's up to Sony to cook the sensor magic.
How is the S10's fingerprint sensor reliability and speed after all the updates? My fingers keep sweating all the time and therefore standard capacitive sensors do fail to unlock phones most of the time. Recently I've tried the Huawei P20 (not Pro), and it's ultrasonic fingerprint sensor was blazing fast and super reliable no matter how wet my fingers were. I don't mind one in S10 being a little bit slower, but does it work nicely even with wet fingers? I haven't tried phones with optic sensors yet, but due to technology limitations, I expect optic sensors to be even worse than capacitive ones in case of wet fingers, whereas ultrasonic, like in P20 or S10 should excel?
My experience is pretty bad. I have dry hands so that might be why, but I absolutely hate it. On the 6T it was always accurate and fast, on the Note 9 it's the best, but the fingerprint sensor on my S10 makes me want to through the phone down a bottomless pit. It's the reason I regret getting the phone.
Fingerprint works fine for me. But when my fingers go dry the ultrasonic is not good. The work around I found is to rub my thumb before using the ultrasonic. Works fine. Other than, it's not super fast to unlock the phone but well I don't have much issue. The S10 recognize my fingers most of the time (dry finger is the culprit definitely)
50/50. It only works half of the time. Really bad.
So i did what i read, i scanned the same finger more than once, and did this with different orientations,
all in all works like charm, at least 9 out of 10
I received an update yesterday with the June security patch. Fingerprint sensor seems to have been improved again

i m still on May patch
I bought it with part reason that this scanner works with wet hands. Well it does....but overall the performance is quite bad. A short tap is all you need to get in,but it needs time to process before youre in. Takes like 1 - 1,5 seconds compared to 0.5 on other flagships. Besides this, it also fails to reconise my fingers a lot.
I only scanned one thumb since that's all I use so that may be the reason mine works 100% of the time. I can't remember the last time mine didn't read the first try.
For me, at start it worked 50/50. But when i added 2 times same finger i use (both thumbs x2) it works 100% of time. But still it could be improved with software.
Well, it seems like everyone's got totally different experience. I've seen that fingerprint sensor in S10 covers really small area, so you maybe have to place your finger very precisely into one spot, so that maybe one factor to consider. Hmm, I guess I'll have to try it myself, but based on your responses, it doesn't really seem to be sensor which meets expectations for flagship device.
Personally, I used to have mistakes because I didn't put my whole fingerprint on the sensor. Now I put my whole fingerprint on the ultrasonic sensor and it works like charm. With dry fingers, I need to put more pressure on the sensor so that the sensor can read my fingerprint properly. At the end I find the ultrasonic not so bad after all. I have 0% mistakes now. For the next generation of that ultrasonic I suppose they will improve the sensitivity of the sensor so that it becomes instantaneous.
Improvements After June Security Update
My personal experience is with SM-G9730 with OEM screen saver pulled off in frustration. I find that ease and reliability of entering fingerprints as well as accuracy and reliability of using fingerprint unlock is improved dramatically after June security update. I B happy!

The sensor itself is already pretty much instant. Give the sensor a slight tap and it will work. The waiting is because of the processing needed. A 3d scan needs a lot more processing to make sure its a valid fingerprint. So i can already guarantee the next samsung phone will do this faster due to a better processor.

The slight tap only work if your finger is not dry. Then yes it works and unlock instantaneously. What I mean is that the main limit of the ultrasonic is the dry finger situation. With dry fingers slight tap just don't work because the sensor doesn't recognize the fingerprint. That's why it requires to put some pressure on the screen so that the sensor can read the fingerprint. Anyway hope the next generation will fix it.

Oh so it's not my imagination, June update did improve the fingerprint unlock. I also have the same positive experience. It's way way better
If I do some yard work and don't wear gardening gloves then it doesn't work as reliably as it prior. Takes a few days until my skin on my fingers repair then the sensor works good again.

So I've had the S10 for a few days now. So far I can say fingerprint sensor is working very well with wet fingers achieving nearly 100% success rate. However, speed differs a lot from almost instant unlock taking about 0.5 sec to slow unlock at around 2 seconds. It is nowhere near the speed of fingerprint scanner in P20, but since it is in display, it is perfectly acceptable to me as long as fingerprint gets recognised reliably.

I can confirm this issue with dry fingers. It needs some real pressure if your finger is completely dry(which my is almost never) and takes some time to unlock.
All in all, it works good to me, with wet fingers nicely compared to capacitive scanners, which is not the case with very dry fingers, as it needs pressure and still can fail many times.
For me it's working fine..trick is you have to put the finger on the right spot
