This hidden Samsung Galaxy Note 9 feature is genius and every phone should have it

This hidden Samsung Galaxy Note 9 feature is genius and every phone should have it
Okay, we might sound a bit excited, but forgive us as if this feature is indeed what Samsung says it is, it could improve the way millions of people take photos.

So yes, we were fascinated when we read about a simple new feature in the camera section of the Galaxy Note 9. The feature is called "lens smudge". Get it?

Okay, if you don't get the idea just by reading the name of a new feature, let us tell you that Samsung seems to have somehow figured out a way to tell you when you have smudges all over that camera lens and now officially warns you to clean the lens before you take a picture.

How does it do it? Magic, of course. Also... we have absolutely no idea. We have reached out to Samsung for an explanation, though, and will update this as soon as we get an answer.


Since we don't know the exact workings behind this magic and since Samsung highlights this as "Lens Smudge Flaw Detection" we do assume that there is some actual detective work being done and it's not just a nice reminder that pops up every once in a while (like it already does on current Samsung phones). Samsung also highlights "flaw detection" in the specs page for the Galaxy Note 9 alongside the new Scene Detection as brand new features. Lens Smudge will notify the user of a smudge on the camera once in a 24-hour period. Still, we don't find an answer to how exactly this feature works and we will wait for Samsung's answer on this to actually understand it.


If this is indeed the smart lens smudge detection that Samsung suggests, well... woohoo! And yes, also yawn, this probably seems like a boring thing for those common-sense people that always ensure their camera lens is clean and that are power users, but you would be surprised to learn how many people we see everyday that keep on snapping photos on their phones with a camera stained with oily fingerprints. And yes, it could be the front, or the rear camera, but a smudged camera almost seems more like the norm for the average user rather than an exception.

So thank you, Samsung, on behalf of the average user for figuring this out! Now, if only more phone makers figured out how to do this...

Whoever made this article has not used another android phone in the past, The pixel 2 xl has this feature, launched almost one year ago. -_-

I have googled for this feature on the Pixel 2XL you are talking about, but couldn't find a thing about it. Do you have a link for me on this feature? Like to read about it, sounds cool.

Search in Google, "Google camera dirty lens warning" and how to turn it on/off. It is on by default by the way.

Note 10's killer feature will be automatic camera wiper.

Someone is missing a chromosome. That feature has been out since at least the S9. My factory unlocked S9+ has it. Guess someone hasn't used a S9 lately..

Thanks for your friendly and pleasant observation, but my logic was that since this is listed as "Smart Lens Flaw Detection" there might be some detection going on. Previous Notes and Galaxies only popped up a notification at random times (but maybe that was my experience with this?) Anyway, we have reached out to Samsung for a comment on this and will update when we get an answer!

Yes other Galaxy device do have a notification for such, but I doubt its using SLFD, which yes does sound like this is some type of hardware assist method for knowing the lens could be dirty. I think the heroes are all in such a hurry to claim there phone does the same thing, they aren't looking at the fact, that something about it is different.

Remember this is PhoneArena. Little bit late with everything. Imagine headlines if iphone have this some day.

It's a reminder that pops up whether your camera lens is smudged or not, and it's been presented on Galaxy phones since the S8.

Which is why I think this is something totally different and more accurate. On the older phones, this notification is random and was put their because the FPS is right next to it.

Victor knows little about non-apple stuff. He should stick with what he knows.
