S4 built in sensors - Sprint Samsung Galaxy S 4 General

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 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....

Waterproof-ness

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.

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

[Discussion] Your favorite GS5 features?

Fingerprint Scanner- Use it for Paypal, unlock device (plus enter privacy mode), and use it to unlock device plus open an app with certain fingerprints that you designate.
Toolbox- Samsung's take on Paranoid Android's "Halo" feature.
Camera- TONS of stuff, new/cleaner layout of all the modes, plus new modes seem really cool. Plus 16 MP is awesome.
Micro SD/Removable Battery- One of the VERY FEW phones that still has both of these, always a plus!
Menu Button- The removal of the menu button and putting the recent app switcher is so much better.
Water Resistant- IP67, and notice how I didn't say WATERPROOF, BECAUSE IT'S NOT!!
Download Booster- WiFi + 4G LTE= DAMN
Better Battery Life- Bigger battery, plus the ultra power saving mode! Already average 25hrs with 3hrs of on screen time with my S4 (stock battery), so I can't wait to see what the S5 can do!
What's your favorite features of the S5?
ISOCELL camera

Micro SD/Removable Battery without question, for me; this combination is why I can't really consider any other manufacturer, although there may be some others with these features that I'm unaware of. USB3 is a nice upgrade over the S4, as is the upgraded CPU. Waterproofing is also pretty sweet, although I've never had any water issues with any phone, and I never use a case because I can't stand the extra bulk. The extra height, width, thickness, weight, and fatter bezels for only a tenth of an inch larger screen, not so much...won't be upgrading to the S5 from my S4, although the S5 is probably overall the better device. Perhaps if there is a "Prime" version yet to come, I'll be waiting for the Note 4.
Good features...try to add more exclusive features

I liked the better battery life, water resistant(IP67) and the download booster.
For the fingerprint scanner, I think it does not fit for Android, especially for secure payments. Android simply cannot keep fingerprint data secure...
1. Ultra power saving mode.
2. Good camera.
3. Water resistant
Sent from Note 3 (The beauty & beast)
Only brand, which still supports removable battry + sd card slot
other than that:
1. Ultra Power Saving mode I really think this could come in handy a lot of times but I think the S4 will get a feature like this too
2. faster auto focus on the camera
I really don't care about the finger print, heart rate that just seems gimmicky and less useful than say air gestures or smart pause. The download boaster is a double edged sword while it's nice to have more speed it will also eat up your monthly limit like nothing so I'd rather download at a lower rate but more.
Surely the best feature for me is the super fast Auto Focus. Damn, it's really fast!
I also like the fact that the display can go down to 2 Cd/m^2. Ultra Power saving mode seems useful too.
Other than that is the Exynos 5422 in the non-LTE model seems pretty cool with HMP possibly out of the box. Looking forward to checking out its performance.
Also, the new Touchwiz looks pretty neat.
Likes: Waterproof, SD card, camera and removable battery which is a must!
Dislikes: Fingerprint sensor, dont need it and hated the iphones for having that, i consider it a privacy issue here, your fingerprints should not be taken via your phone, it would be awesome if Samsung would make it optional for this "feature"

It is optional. Like with the iPhone, no one is forcing you to input your fingerprint and use the feature. If you don't want to use it, simply don't use it. It's not required by any means.

LG Watch Sport or Casio Protrek WSD F-20?

Hi all,
I am dilemma between LG watch sport (W281) and Casio Protrek WSD F20. Any suggestion?
I have both and each has it's own strengths and weaknesses.
LG is more refined and premium looking, has radio and HR sensor embedded, which I use from time to time and has amazing AMOLED display.
Casio on the other hand is more rugged, has offline mapping software based Open Street Maps (which I used often) and you can partially use it even when battery is almost depleted (it switches to second layer clock only display). The display visibility is pretty bad under direct sunlight (thanks to dual layer display probably).
I like them both

Thank you for reply. The only thing i don't like about LG Watch Sport is its strap which is not interchangeable.
Protrek does not have HR sensor, LTE etc... I still don't know what to choose

I found it huge on my wrist, and rather 'plastic' looking.
No comparison in my view, unless you need the Casio speciality functions.

OnePlus 5 NFC antenna placement

Hello dear community,
I've been thinking of trying some NFC buttons for a while. Dimple.IO and Air Button have caught my interest some months ago but never acted on that interest. Until now...
And, since I didn't want them to fail from the start, I checked the responsiveness of our beloved OnePlus 5 to NFC tags in general. The results are pretty disappointing...
Basically, if you don't want to cover the camera module with the tag, you only have the indicated sensible areas on the phone (solid red, see attachment). In any other area, the tag is not recognized.
I could understand OnePlus' decision to put the antenna there. There is not much non metallic surface left on the back of the phone. But this placement might prove itself rather bad for the integrity of the camera (at least most of us don't use NFC that often) and it is certainly making the use of the mentioned NFC buttons impossible.
What are your opinions on the subject? Has anybody else tried to pair the OnePlus 5 with an NFC button? Has the placement of the NFC antenna ever bothered of annoyed you?
Thanks!
Well, the result is as expected with a metal phone. NFC works OK, but you do need to hold it in a certain way.
On my OPO it was much simpler since it had a full-back NFC antenna.
If I use my phone to pay at a terminal I can have it away a pretty decent distance for it to work so I'd say the nfc is pretty good.
@DevSquad: I understand the implications of a metal back. (good and bad) @B0unze: The terminal has an signal amplifier, so longer communication distances are possible. On the other hand, tags are passive, everything is done by the phone, hence shorter distances are needed.
Well, I guess it is just my specific case and I will have to live with the situation. I wish the NFC antenna would have been placed along the top edge...
AFAIK the NFC antenna is embedded into the upper edge of the protruding camera lens. Its barely noticeable, but you can see it.
I thought it s all around the camera protruding. My bad... lack of info...
Then it makes sense that NFC tags are only activated around that area. Oh well... Too bad...

Low temperature shutdown issues

Hi
I am into hill walking and mountaineering. I am finding that my note 8 will shutdown if the temperature is below about -5C and I start the camera to take some pics. Once it's shutdown, it will refuse to start until warmed up, and needs a soft reset. It also comes back with 5% showing in the battery but had 80% at the time of shutdown.
It's rather a pain in the neck. My old Xperia Z5, Z3C and Z1 would do -20C without ever having issues.
I am assuming this is just an annoying 'feature' of Samsung devices rather than a fault.
I am thinking of running a background number crunching app to prevent deep sleep! Samsung is not interested, wondered if others had the same issue. If I stick my old Z5 and the Note 8 in my freezer at -15 for an hour the note 8 shuts down, but the Z5 carries on as normal. Prob down to cheap/nasty battery tech in the note 8.
Nigel
That is interesting. I'm going to northern Japan this Sunday for 3 weeks. It will be snow and freezing cold. I'll report back how my Note 8 works there. I really hope mine won't shutdown when i really need to use it.

That's a lil concerning -5C = +23F. Last week it was negative -10F here. I was shoveling snow for about an hour, big driveway/sidewalk path aka snowblower needs fixed. I took a few pics and took some calls/text. No shutdowns here. Now at the same time shoveling snow takes a lot of work so maybe my body heat was keeping it warm in pocket.
But at the same time the same could be said about what your doing and body heat idk. We need more people to chime in.
Oh bonus people in hot climates don't be afraid to chime in. Curious how this phone handles the heat. Gets cold here in winter, but really hot and mushy in the summer.
Hi
Mine is not in a pocket, but rather mounted to a chest strap on rucksack so it gets full force of cold and wind - exactly the same as my old Z5 - reason: it is also my GPS for walking and ski-touring. Maybe you can leave yours out in the cold exposed for an hour, then try taking a photo and see if it shuts down?

You could put it in a crown royal bag with a handwarmer. Would probably keep it warm enough. I live just 80 miles south of Canada in the PNW. It was 7 degrees last week. I left my phone in my car for a while and it was fine. It was really cold, but still working.
it's a glass phone. there is nothing under the glass but the components. that's the difference between it and your sony phone. glass is not a great insulator
Aye, might offer a work-around but not a particularly convenient one. I'll be back with Xperia end 2018 when I am due an upgrade. The phone only appears to actually shutdown when the camera is started while its cold. Must be high current draw, causing a voltage drop that gets detected and the device gets shutdown. Love the screen and pen, and camera, moved from Xperia after three separate devices as they looked old fashioned with their HUGE bezels, and refusal to adopt wireless charging.
It was 2 degrees F here in Nashville TN last week, but I stayed indoors and didn't go outside for any length of time to see how my phone would have been affected. Had some friends who went to the Jacksonville/Tennessee football game a couple of weeks ago.........16 degrees; they left early because they couldn't feel their limbs even with multiple hand/foot warmers...............I wonder how they kept their phones warm.

Its a glass phone in a heavy duty rubber case that I stuck it in! Both phones have a glass front! The wee bit of alu on the rear of the Z5 vs the glass on the Note 8 should not equate to a 15C difference in the temperature the device can withstand while continuing to function. I suspect the real reason is inferior battery tech vs Sony, and over-zealous low voltage detection and device shutdown.
I note that my Samsung 360cam also shutdown due to the cold this weekend gone, but my GoPro kept working.

this could be a result of sammy overcompensating for their note7 debacle last year. the fact that root limits my battery at 80% says a lot.

Isn't that 80% thing due to locked bootloader on Snapdragon? Root on Exynos doesn't have 80% issue, so not sure it's related to those Note 7 problems. The camera issue itself might still be though.

you're right, it is due to locked bootloader and the detection of root. it is no mistake that 80% is the cap when rooted. samsung did that on purpose. it started on models released after the note7, which is why i suspect they are weary of battery troubles, and if you root and begin to alter the system, the chances of an incident go up.
what camera issue are you referring to?

I will do that for you. I have a porch on my 2nd floor room. We're supposed to get 6-9 inches again this weekend with below temps close to 0 F maybe below. I will leave it out for an hour then try to use it. Probably will have same problem as you I am guessing.
Especially when phone is exposed like you pointed out and no body heat to keep it warm. Like others pointed out which forgot glass sucks for insulation. But at the same time I thought the note had a few layers of glass? The best house windows are double and tripled layers sumtimes more. They offer good insulation.

Great, thank you for confirming. The camera issue was the one mentioned by OP regarding trouble in colder temperatures. I just meant that while the 80% battery limit wasn't related to battery concerns or safety measures, I can't say with the same certainty that the camera issue described by OP isn't somehow related to that.

Maybe triple pane windows are made from a special type of glass? Or perhaps the spacing between those layers provides insulation not present on our phones? Not sure, just speculating here...

Yeah idk crap a bout house windows lol. You're right they're made out of special glass I believe and spacing exists. Would think even few layers of glass would make some difference in phone? But I am no expert on glass and insulation. So I will just shut up lol.
glass,plastic,metal or whatever material wont do any difference in cold weather with prolonged exposer.( case or no case)
if it takes 10 minutes to get to minus 5 or if it take 30 minutes, you still will get there. the question at hand is at what temp does the phone stop( if it acctualy does).
