Interesting Findings with the Fingerprint Scanner - Samsung Galaxy S8 Guides, News, & Discussion

I recently was toying with my S8 when I stunbled across an interesting find. As you know, the S8 has a built-in fingerprint scanner that uses fingerprints for various security measures. Did you know that you can use other parts of your hand (and even feet, not that it's useful, just interesting) to unlock the phone. You can register the pads under your fingers, the side of your hand, the pad below the thumb, etc. Honestly, this is probably already well known or just common sense that it would work given what the technology is, but I just discovered it, and I find it neat. You can use a different part of your hand to increase your security, as it is different from your fingerprints.

hahaha you sat there with your toes on your phone didn't ya?
But no, yea. Fingerprint scanners record the friction grooves on your finger tips. The same grooves that cover your entire body, but its easier to quickly scan your fingers then anything else since they're right there and we use them for everything pretty much. Your hands and feet friction grooves are more pronounced then anything else since their rough, you don't walk on your forearms and grip things with your face. Scanners have gotten more accurate which make them better at reading the softer grooves.

I know what part I'm gonna use!!!

Sena Ultraslim Cases Now Available for Infuse 4G

They're in stock and available now. This has always been my favorite case. I don't like things that inhibit the phone's thinness\natural design, so I like slip-in sleeves, and Sena makes a good product.
Look around on the net there are 20% off coupons... their ordering\delivery process leaves a bit to be desired, but the product is good.

I guess its not as classy as a chunky shell case. Nothing sexi bout those.
If your looking for slim cases check out the casemate barley there. its very nice and even came with a screen protector. That I dont use haha.
This is a Sena pouch, not a case as you have to take the phone out of the pouch to use.

You're wrong actually. Time for English 101.
Dictionary: "enclose in a protective container" so in face the item that you refer to as a "case" is not a case, it's a backplate, or protective shell. A true case, by definition, en"cases" the item for protection. How does one access files in their briefCASE when they need them? They take them OUT of the briefCASE. How does one change clothes when they get the hotel? They take their close out of their suitCASE to use them. How does one get the term nutCASE? They take silly comments out of their head and place them in places like here, where you said SenaCases.com isn't a case website.
If you use the phone when it's in a case, it's not a CASE.
I completely understand the non-literal definition of what's included in the word "case" has become lose over the years... but your comment was just inaccurate in every way.

I had this case for about a day, and returned it.
- renders the OEM desktop dock worthless
- renders the OEM car dock worthless
- makes the charging cable not fully click in to charge w\ cable
- collects dust under the back part and gets a little icky
- provides no screen protection & screen protector makes resolution grainy
These were just my reasons for returning it. Not sure why you posted this in this thread, rather than in the general cases\shell thread, but I thought I'd reply with personal experience as to why I bought then subsequently returned it.
It's just my personal opinion, but if baffles me why people buy these shells. Even at the 3mm thickness of this case, it adds 3mm to the back, 3mm to the right, 3 mm to the top, 3mm to the bottom, 3mm to the left, and then a 3 mm lip around the phone. Add those all up and it equates to double the tickness of the phone to begin with. The idea of having a thin and light phone is so it's thin and light. I suppose if I were the type who dropped my phone frequently, having a plastic shell around it might be useful, but that's just not me, which is why I went with the slip-in sleeve as I posted above. Provides dust\pocket protection, cleans the screen, but when the phone is in hand it's in it's full thin state as intended by the manufacturer.

Can I post it? What do you mean? It's the same as googleing "Samsung Infuse Desktop Dock".... but will save me from taking photos, and will save you the wait, hehe.
I love it... I've always had a dock for my iPhone, so when I heard it was coming out for Infuse I jumped on it. It's great, just slip the phone onto it and it charges\syncs, and makes it a lot easier to see texts\emails because it's angled toward me and not just sitting on my desk flat.
It's really not a huge amazing revolutionary thing, it's more of just a convenience thing to make the phone more usable for my tastes. And much of it is just cosmetic.

I agree. This looks like something a girl would keep the phone in while in her purse. It provides no protection if you happen to drop your phone while you're actually using it. Pointless for me...perfect for the ladies. Hehe
And Bella, you can quote the dictionary all you want, but most people would consider that a pouch, not a case.

I guess if you're too clumsy to hold a phone in you're hand, then you need to get a shell that will double it's thickness. I guess you're right, if you're a man and insecure about... the ability to hold your phone due to it's small size, it might be in your best interest to explore enlargement options that'll make it easier to find, larger to hold, etc.

Its my opinion. You oviously have yours. If you need a pouch to keep your phone in while in your purse so your lipstick doesn't scratch it, that's fine. Nobody wants to deny you that option. Enjoy!
The personal attacks are so unnecessary.
I'm sure you're well on your way to getting all your threads closed and eventually banned. Can't wait!

Huh? How is it a personal attack. If someone drops their phone regularly, wouldn't that classify them as clumsy?
Clumsy: awkward in movement or in handling things
How is that a personal attack? You seem overly sensitive, almost like you've got a victim complex... you are wanting to be offended. I've never dropped a phone in my life... and unless I were to drop it regularly, say once a week or so, I probably wouldn't be willing to double it's thickness to protect against the occasional drop... but that's just me.
And I could say your comment about purse and lipstick are closed-minded, offensive, but I won't.
I'm starting to see a trend here... I don't want to act as a nanny, so please, stay on topic.

Sorry, didn't mean to offend or get personal... unfortunately when I post about a case and someone else says it's girly, it's off topic. God forbid girls actually want a case for their phone. Or heaven forbid a guy who's secure in their manhood want a case thats fashionable instead of 1980s industrial. hehe
Anyhow, I gave a piece of advice about a case that I love, so if others don't like it then they can buy their plastic shells, I was merely trying to help.

[Q] Motorcycle Mount

Anyone found a good option for a motorcycle mount?
I have found a few.
One encases the whole unit in a waterproof case
Another that hold it upright on the handle bars
and the otterbox one.
Anyone have any real experience with any of the mounts available?
Yeah man, what I did was I bought a sidecar, and i superglued a car mount in that.
From what I have seen in some cycle online groups, RAM Mounts (google that, they'll pop up) seem to be pretty highly regarded. The are not, however, the least expensive option but they work well. It looks like they offer a sealed box and mount combo.
I have the one from "slipgripcarmounts.com" works really well.
RAMS look excellent but their pricey.
Thanks for the ideas!
Due to the Epic screen not working that well through gloves, I would really like to find one that would allow the keyboard to slide open while mounted. I have yet to find anything for this model though.
If I can't find anything soon I think i'll have to make one. I've already thought up a good design, i just have to figure out how to make it or convert one of the existing ones.
Hopefully something already exists and I just have yet to find it.

I understand the issue. I thought about that too but then realized I wouldn't be able to work the keyboard with my gloves on either. So I just cut off the tip of the right index finger on my riding gloves.

Crumbs getting lodged down side of screen?

Is this annoying the hell out of anyone else? The gap is so fine not even a pin gets them out. A needle only works sometimes. Any fixes?
Sent from my Nexus 5 using Tapatalk
Same problem with me man, I dont even know where they came from, its in the bottom bezel of mine, I managed to clean most of it out with a safety pin but if you look really close you can still see them
I use a piece of paper to slide through it. Works well for me
Sent from my Nexus 5 using xda app-developers app
Might try to use a can of compressed air too.
So it's not just me, then!
Ah, it's good to hear that I'm not the only person with problems over the industrial design of the N5. I hate the nasty sharp edge round the screen! The N4 feels so much nicer in the hand. And it doesn't fill up with muck around the bezel.
Hahahaha just the thought of you eating a sandwich and crumbs falling onto the phone.
But yeah I got various bits of dust/ crumbs in the bottom bezel. Like they said, a piece of paper or a pin worked pretty well. Still an annoying oversight.
Had the same going on. Just used a small needle and all is good.
Canned air works great or if you have a case on it like the Spigen hybrid like I do, you could just blow on it really close and are able to push a lot of air pressure against the case.
Thanks for the paper tip!

I might ruin yours and everyone elses day here, but what about between the lens and the plastic casing around the camera.. that's what's bugging me at the moment there must be some variations in build quality, because NOTHING can get down the side of my screen, even paper creases.
Always use the edge of a piece of paper to get dust/lints/crumbs out from the edges. IMO using a needle/pin will eventually enlarge that gap and cause more crap to get stuck in there.

Also, a needle has potential to scratch if not used carefully.

[Q] Get Dust Out of Speaker Holes?

Does anyone have a good method of cleaning out the tiny holes for the speakers? I have a few filled up with particulate and was wondering on the best way to clean them out.
A pin maybe? Or a little vacuum for keyboards?

No problem, only thing is dont get on you screen protector. pulled on a corner on my zagg.
Also note that not all holes go all the way through.
If you look close, a little less than half of the holes(on right side) on both the upper and lower grills are merely cosmetic and don't go all of the way through.

Fingerprints scanner wont work on any cases

Just "found out" that the fingerprints scanner will not work on any cases because your hand need to touch the metal parts on the sides of the phone in oder to make it work (if u dont want ro cut a hole on the side of the case).

Run a piece of aluminum foil inside your case, so that your finger touches it when you cover the button. This is the only "fix" I've seen for this issue.
I have a slim armor case and fingerprint scanner works fine.
Hang a metal coat hanger out of the headphone port to give you connection.

A bit of aluminum tape is a quick, cheap solution, and it's easily reversible once the update comes through

It's a software issue. The Verizon versions been updated. T-Mobile hasn't. Not sure about others. There might also be some variation between different cases or even between different people
