Galaxy Note

It has already been confirmed by Samsung that the Galaxy Note 4 will have an ultraviolet (UV) sensor, but there wasn't much information available. Now, according to a report over on SamMobile, we have some idea as to what consumers can expect to see from the built-in functionality. The new component will integrate itself within Samsung's S Health app, providing yet more personal data for the owner to take advantage of.

Is it gimmicky? Sure. It's Samsung, the home of the smartphone heart-rate monitor, but it is cool at the same time.

So how exactly does the UV sensor work? It measures the sun's ultraviolet radiation and prevents owners from potentially damaging their skin, increasing the risk of skin cancer. This is possible thanks to recommended guidance provided, based on the current UV index level measured at that point in time. All that's required to measure the radiation is to maintain a 60 degree angle of elevation towards the sun against the back of the sensor.

We noted that it's a useful and rather cool feature simply because people are generally fairly ignorant when it comes to keeping safe in the sun. To help keep everyone safe from being exposed to too much UV rays, Samsung will provide a full explanation on each level of UV index level, as well as some cool truths and false statements in the app.

Here's the information that will allegedly be included in the app, as outlined by SamMobile:

The truths:

  • A tan results from your body defending itself against further damage from UV radiation.
  • A dark tan on white skin offers only limited protection equivalent to an SPF of about 4.
  • Up to 80% of solar UV radiation can penetrate light cloud cover. Haze in the atmosphere can even increase UV radiation exposure.
  • Water offers only minimal protection from UV radiation, and reflection from water can enhance your UV radiation exposure.
  • UV radiation is generally lower during the winter months, but snow reflection can double your overall exposure, especially at high altitude. Pay particular attention in early spring when temperatures are low but sun's rays are unexpectedly strong.
  • Sunscreens should not be used to increase sun exposure time but to increase protection during unavoidable exposure. The protection they afford depends critically on their correct application.
  • UV radiation exposure is cumulative during the day.
  • Sunburn is caused by UV radiation which cannot be felt. The heating effect is caused by the sun's infrared radiation and not by UV radiation

The statements below are false:

  • A suntan is healthy.
  • A tan protects you from the sun.
  • You can't get sunburnt on a cloudy day.
  • You can't get sunburnt while in the water.
  • UV radiation during the winter is not dangerous.
  • Sunscreens protect me so I can sunbathe much longer.
  • If you take regular breaks during sunbathing you won't get sunburnt.
  • If you don't fell the hot rays of the sun you won't get sunburnt.

What are your thoughts on said functionality?

Really?? Is there anything else that can be done with this sensor?

Samsung: How can we add even more bloat to our phones?
Answer: Add another useless senor and some badly written software to run it.

I almost think that is how they work at Samsung today. The bloat and lag it causes is just beyond insane.

Funny that it's always bloat until it's later introduced as really useful features in Android. Latest example: Knox, which was the root of all evil until Google adopted it.

In other words: Haters gonna hate.

Belatukadro says:

Knox has always been a really great enterprise security solution. And there have been some features Samsung added that were genuinely useful and eventually rolled into Android, such as notification shortcuts.

However, there is little denying that the lion's share of their software additions in the past two years have been either barely situationally useful, poorly implemented, or both. All of the Air gestures (remember those?), the Smart _____ features, the fingerprint sensor, and the heartrate sensor definitely fall under those categories. This UV sensor looks like it tends in that direction, based on: 1. it must "maintain a 60 degree angle of elevation towards the sun against the back of the sensor" while the sun is moving through the sky; 2. the sensor can't be covered by any film, glass, oils, dirt, cases, etc. or it may malfunction or give an inaccurate reading. And further, in the places where this would be marginally useful, most people won't be likely to have their device out, or even think about using it to measure such things. Which would make the feature just another bullet point on the spec sheet, and not much else.

bswitzer1 says:

"While the sun is moving through the sky." The sun does not have a large degree of travel through the sky during which would probably be a minute scan or less to determine the UV level. Also this would be extremely helpful here in Florida, especially in Central Florida in the theme park industry.

Andres Reano says:

The sun doesn't move through the sky.

bswitzer1 says:

You are correct, the earth rotates on a axis that that perpendicular to the suns position on the equator of the earth... Now that we established that and that we all know what it meant when we say moves through the sky, please sit down.

WinOMG says:

Hey I'm in central Florida!!! I'm in between Orange City and Sanford.

Ever heard of relativity?

Dizfunctions says:

Knox has always been great for enterprise, but for people who wanted to mod their phones or root, it caused problems since Knox would let service providers know that the phone had been rooted in case any warranty work was necessary. If Google makes using Knox - like features optional, people would be much more open to having Knox like features on their phones.

Plain and simple nothing beats Samsung or the Galaxy Note products period they are the GOLD standard of technology today.

Time has come for the pretenders to fall back and realize it's SAMSUNG who made the phablet category prominent today and now all the rest must follow.

At the end of the day it's SAMSUNG who is Android without Samsung Android isn't worth a hill of stale beans.
Just like usual I will be purchasing the Galaxy Note 4 day one of launch for Tmobile nothing else has ever mattered.

gregg37 says:

No. Dumb reply. How about Just don't put in garbage that 0.00002% of the people who buy it will use. I don't care if it's dirt cheap. Stop adding proprietary gimmicky garbage. The note line is a great line of devices, and it's not because of dumb crap like this.

Deke218 says:

I'd agree with ridgeline1234 - Don't like it, don't buy it. It is because of "dumb crap like this" that the Note is such a great series for Sammy. Give me gimmicks Sammy! If I wanted a phone without the bells and whistles, I'd get a crap Moto or Nexus device. The S Pen and it's features are a gimmick. Still, very useful.

TenshiNo says:

If Sammy was afraid to sell "gimmicky" devices, the Note series would have never been created in the first place.

But proprietary gimmicky garbage is what Samsung does.

NoNexus says:

No what they do is make great phones that you happen to hate.

Big difference.

No, I hate that they are filled with proprietary gimmicky garbage.

NoNexus says:

Find me a phone that does not have proprietary software. Don't say Nexus because you would still be wrong. Some of the stuff is garbage (the stuff that they duplicate from Google) the rest is VERY useful depending on peoples needs.

TenshiNo says:

Agreed. I doubt anyone uses *all* the little "gimmicky" features, but there's nothing that says you *have* to. And the features that you do want can be immensely useful.

Techngro says:

Um...you say 'my phones' like you're the one who made them and Samsung just walked into your house and dumped their software in 'your' phone.

It's Samsung's phone. Not your phone. If you decide to buy it, then you take it with all the 'useless shit' that you knew was there BEFOREHAND and stop whining.

D13H4RD2L1V3 says:

It seems useful, but I wonder how many people will actually use it.

Not to mention the Note is kinda on the large side for something used for fitness.

Sitting on the beach or in the greens in a park hardly counts as fitness.... :)

D13H4RD2L1V3 says:

Well, I guess it could work......unless you're smart enough to sit under a shady tree.

You're missing the point completely, deliberately as usual?

D13H4RD2L1V3 says:

Wait, what? 6_ 9

=) just not in a mood for discussing stuff today.... Too hot...

Anyhoo... When you sit in the sun, you sit in the sun. Not the shade... That's the whole point with sitting in the sun :)

gregg37 says:

ZERO people will use it.

D13H4RD2L1V3 says:

Correction: People will use it at the store, then completely forget about it once they buy it.

NoNexus says:

No they do not.

D13H4RD2L1V3 says:

I'm pretty sure that there will be a group that will use it on a day-to-day basis.

But I still believe that for most people, it's a novelty.

NoNexus says:

But isn't that the same with most features? I might use 75-80% daily, but the rest are used sporadically. You cannot make a phone that is specifically targeted to just one narrow group. You have to be a jack of all trades to sell volume. I have said that the duplication of google apps are stupid, but the rest are there for when you need them, even if you never do. It is better to have them and not need them, to need them an not have them.

TenshiNo says:

jimbo says:

FACT
It's already proven, most have no inclination to use nor figure out how to use the vast majority of these gimmicks.

Got to hand it to Samsung to be the OEM with the resources to throw it against the wall in an effort to see what might stick in what appears to be a desperate attempt to gain further dominance.

Apparently, this shotgun approach and accompanying lack of usability seems to be coming home to roost with their recent dramatic market share decline among cleaner and more sophisticated and focused competitive offerings.

NoNexus says:

Citation needed.

D13H4RD2L1V3 says:

You sure about that?

Last time I checked their market share isn't dramatically declining, but their profits are coming down.

NoNexus says:

R & D costs money. I believe that they spent the money to make it up this year. All those great lines of tablets, the Note 4 YOUM display, the watches. Those things costs money to develop and they will recoup those expenses in the next year.

D13H4RD2L1V3 says:

Not to mention the increasing strength of the Korean Won over the US dollar.

I think the idea of such a sensor isn't bad, but it might make much more sense in a watch. The only problem with a watch might be the limited space they've for such sensors because I would guess that it would have to be next to the display.

Hiberny says:

Great idea. I'd buy a watch with a UV sensor. But I don't know if I really care about it in my phone.

I can not wait to Note 4 comes out. I Love Samsung Galaxy Notes huge screen and I love the S pen too. No other phone can beat the Note. So if you're looking for one of the best phones out there so you should look no further ;)

Except the battery on the G3 outlast the note 3, but you have a point about the LG ui although I prefer it over touch wiz anyways how did this conversation even come up about the G3?

So far I have had my G3 for a few weeks (work tester) and I can say you are wrong. My Note 3 outlasts the G3, for my use, so far. It has been an interesting experience so far with the G3.

I wish they would focus on keeping the Note series as a "productive" line. I use mine a lot for work and enjoy the added features of the S-pen.

Let the GS5 be the sports/health device. Give me productivity and battery life on my Note!

theShiz says:

I don't like Apple devices personally, but they won't ever do the stupid things that Samsung does. The only loaded Samsung branded app I really enjoy on my Note 3 is the remote, and Beep'nGo, but beep is third party. I don't even like the split screen because it only allows handful of apps to be used. All that eye scrolling crap excetera never sees the light of day. And of course I use Nova launcher to make up for all the rest. I do use the pen for swyping on the keyboard. I pretty much like the Note 3 for its beast speed, battery life, size/screen, and the fact that it will probably get update support for a little bit more than average. Right now I have 46 useless disabled applications on it and that doesn't include the ones I can't disable. Apple would never do this.

NoNexus says:

So you crippled your phone.

I agree that Samsung needs to stop duplicating Google apps, but (outside of the eye scroll "crap") all the other apps can be very useful in the right situations.

sublimaze says:

Thanks but I'll just check the UV index on the weather report.

Finally someone thought exactly the same thing that came right to my mind.
UV rays are not like rain. It's not a matter of getting wet or dry. It's the amount of radiation that you're willing to take.
Predicted radiation levels are more than enough to make a decision and a UV widget will do much better and quicker than a sensor.

NoNexus says:

SO the weather report will tell you the amount of UV rays you have taken in so far in one day on the beach?

jimbo says:

Obviously YES
Much better than this cockamamie gimmick

NoNexus says:

SO when I go to weatherbug, it will tell ME how long I have been outside, how many UV rays I have taken in, and whether or not that I should still be out there.

Dumbo, read what is written, not what you think I wrote. You are not smart enough to make suppositions.

jimbo says:

So you will be 'that guy' who spends the entire day at the beach while maintaining a 60 degree angle of elevation towards the sun against the back of the sensor on your Note 4.

NoNsense! Pure fanboy NoNsense!

Again you step in your poo!

NoNexus says:

No Dumbo, not at all. I might never use it, but I will be glad it is there if needed. I do go outdoors a lot and am very active.

You should get out of mommy's basement more and give it a try.

Oh and once again, read what I write, not what you think I write. I said, in the proper thread, that I would take the G3 over the S5. Fanboi? Only of your mom and sister. I cannot shake that habit

TenshiNo says:

"60 degree rotation to the sun"

...like... lying face up on a flat surface while the sun is overhead? Yeah, that sounds really unlikely.

this sensor is stupid there is no reason to check ultraviolet rays
if the sun is hot there is lot of UV same if its really bright
how about a suncream dispensor on side of phone to squirt on you

There is a widget in TouchWiz for that. At least that one lets you turn the flash light off in the pull-down menu... :)

21stNow says:

For those saying that it's a useless gimmick, I don't understand what the complaint is. Samsung alone offers so many different phones (Mega, Avant, Galaxy S, Galaxy S Active, etc.) that you can avoid this gimmick if you choose and still end up with a Samsung device. Other OEMs offer phones with the Android OS so you can enjoy Android and avoid Samsung altogether.

While I don't think that the UV sensor will be useful for me, someone else may find it useful. Some people may think that Smart Stay is a useless gimmick while I appreciate the feature. There's too many options out there for people to be upset about this.

Dominick079 says:

The only issue I have with Android phones is the ability to completely remove the bloatware without rooting your device. We should be able to do this. On the other hand some people find some of these apps useful.
