Why do they put the fingerprint sensor behind the phone? - Nexus 5 General

Hello fellow Nexus 5 users,
Like most of you, I have owned this beloved Nexus 5 since 2013 and feel it is time to upgrade. My original battery has gone downhill and I had to replace it with the battery from my brother's old device hoping it would last me until I got a new phone. I was thoroughly intrigued by the OnePlus3 but have decided to wait until the new Nexus drop before purchasing a new device. With the previous N5X, N6P, and the latest leaked images of this year's Nexus, it seems that the finger print sensor will once again be on the back of the phone? This makes absolutely no sense to me because if the phone is sitting on the desk, you have to pick it up or you have to resort to the old way of unlocking the phone. Also, if the phone is sitting in a car dock, the finger print sensor on the back will also become obsolete. Lastly, I'm a big fan of those wallet cases where the back cover has a slot for a few credit cards, which is also blocked by the finger print sensor if it's on the back. Why would they not put it on the front of the phone?
The Nexus 5 was a great phone, I hope this year's Nexus has the following:
-Same screen size
-Larger battery (at least 3000 mAH)
-Latest SoC
-A camera that is on par with the S7
-FINGER PRINT SENSOR ON THE FRONT OF THE PHONE.
Would buy in a heartbeat.
What say you?

it really depends on the use case.. for me, fingerprint sensor on the back is the most natural way to unlock with my index finger..

Agreed, since the size of these new phones are huge, it's easier to unlock the phone with the index phone if the sensor is at the back. For a smaller phones (e.g iPhone 5S) I would prefer it in the front bottom though.

maybe to avoid wear and tear? as we always use our home button. and i think its one of the signature of nexus devices the nav bar.

I like the clean look of the Nexus 5 with nothing on the front so I would prefer it on the back. I don't ever interact with my phone when it's laying on it's back. If I use my phone, I pick it up. It's not like the old way of unlocking is hard or anything to make me complain about not being able to get to the sensor easily. And if it's a debate about PIN vs Finger print sensor, smart lock usually gets rid of the PIN anyway in most places for me. In my opinion, the finger print sensor is just another added method to unlock the phone and not the primary method. So I prefer it on the back.

I use fingerprint sensor all over my house I have it for my bedroom door my, front door, my office and my grow room
Also have one on my laptop and I don't use my index finger on a single lock I use my thumb so yeah a sensor on the back is worthless to me cuz it would be the only one using index o will simply turn it off and use smartlock as my watch unlocks my phone the second I'm within ten feet of it

Tips on Adapting to a Huge Phone

Share your thoughts/tipsand tricks on how you use this beast on a daily. Being almost 6 inches in screen size, this thing isn't what I would call the most pocket able or friendly on a daily basis.
im 5'7", average size. have average sized hands. id never ever say that the phones too big. sure, it sounds big, but isnt. after several days of using it, my nexus 5 feels way to small now.

Hear hear @simms22, 2-3 days is enough for your hands and brain to get used to it
On the other end of the spectrum, I'm 6'8" and the phone looks like an iPhone 5 in my gigantic paws. However, I do use my little finger as a rest, under the phone while using it one-handed. I have no issues reaching any parts of the screen but the pinky finger underneath adds some stability.

To be fair, anything above 5,2 inch is almost juggling when trying to use it one handed unless you have Micheal Jordan hand size
Easy transition and has a comfortable feel. Most other device's now feel too small!
I'm 5'2 and have tiny hands, it took me about a day to get used to the size. I seriously forget the size of the phone until I put it in my pocket, that I cannot get used to for whatever reason. Also when I'm in the car and forget it doesn't fit in my cup holder lol The one handed part I don't really have issues unless whatever I'm trying to press is at the very top right part of the screen but I manage.
Using it one handed isn't an issue for me. I'm 6'7" and I wear XXL sized gloves. But it did take me a couple days to adjust to the new feel compared to my G3.
However, be careful when the phone is in your pocket and you're wearing shorts (especially athletic shorts) and your are sitting down. I've owned the phone for less than 3 weeks and it's already slid out of my pocket and hit the ground on multiple occasions (no damage fortunately).
I came from Note 4 and nexus 6 feels much better in the hand. I find my self sticking the phone in my jeans back pocket a lot and it works perfect. I even sat on it numerous times and this monster of a phone doesn't even care lol
When I'm at work (no jeans) I got used to carrying the phone. Otherwise, front pocket works just as good.
Mine is always holstered to my pants pocket, else I carry it in my hand for quick needs.
In the car, my Subaru has a sliding cover over the cupholder section before the center armrest, and my phone sits on top of that nicely.
In the supermarket, I keep the shopping list in my phone, which is quick to detach from the holster with one hand, unlock via the pattern with my thumb and see what's next on the list for nearby aisles (then, place it back in the holster). Usually one hand operation while the other is holding a shopping bag - if I have a cart, might use two hands for added convenience. I'm 5'11.5"
As most others mentioned above, it doesn't feel huge after a couple of days or so - frankly, everything else looks teeny, now. I can't see going smaller than this in the future, it's become a perfect size for my range of needs with it.

Favorite feature of Note 7

Mine is being shipped however what is everyone's favorite feature or design on this new beast?
Sent from my SM-N920T using XDA-Developers mobile app
This is my first Note so everything to me is great. The S pen I love and the screen. The only complaint is I wish the screen was a little wider. I know the measure from the end of the curve. If they would have made it 6in with the curve would have been perfect.

Old phones in my sign.
But the best part of the notes have always been the spen to me.
I had the note edge and it was lovely then the s7 edge was great but i missed my spen.
but im sure your fine alot your like when you get the phone.
Iris Scanner.... That's really cool.
Using the S-pen to take quick notes without having to turn on the phone, That comes in handy.
Being Waterproof saves alot of worry.... I'm in Fl, always around water.
Iris Scanner hands down.
My wife says I've a line for an eye and it can detect my eyes. LOL
Then tried to have my co-workers and friends tried to unlock it and they couldn't :good:
During registration It did ask me to open my eyes Wide, as the first attempt didn't work with normal eyes position.
The new fingerprint sensor is waaaaay better, this one actually works, previous models it simply didn't work right, so I always ended up disabling it.
This one, you simply touch it, and it opens up the home screen as it supposed to do.
Quick frankly the Finger Print works even better than the Iris scan, as it's more natural.
Whenever I turn on the phone, it's always through the Home button.
Coming from the S7 Edge so a lot of features I already had. I do love having my S-Pen back and the Iris Scanner is really cool. However my favorite features is the improved UI of the camera. The camera on the S7 Edge was the best I had used on a mobile devices, but the new interface makes it so much easier to use the extra features. Direct feed to YouTube Broadcasting is great to have.
Maybe not exclusive to Note 7. but the camera's focus speed and picture quality is really great, makes DSLR almost redundant. Of course S-pen is a signature of all Note series and main reason I won't buy another make, but improvements to s-pen are more incremental over previous models, than drastic. Also screen is probably one of the best, if not the best on the market ATM. And water proofing is one thing less to worry about.

Yes, indeed. I live in Florida and Im also a swimmer. Even though Im not planning to submerge this pricey beast, Im always around or in a pool, so a huge extra level of protection
This is my first note device and can easily say it's the S-pen that has me hooked. I've been constantly using it but if I'm not using it im most likely clicking the top of the pen non stop. A close second has to be the iris scanner.

I have had every single not and Galaxy device to date. I am really excited about the water proof finally. A note that has it!

did you setup the fingerprint correctly?
I know the note edge (n4) you had to swipe down which just suck.
The s7 edge was a press one. It work really good.
I always setup my fingerprints by turning my finger 270degs. making sure it gets my finger from all sides. I even go a little above the pad.
Work great for the s7 edge. but yes the note 7 FP is much faster and success rate is higher

This finger print thing

Actually not very good is it, not because it doesn't actually work very well unless you are stationary sat at a desk, but walking along with the old one your finger found the pad on the back really easily.
Now it's an utter faff, just so they can show off technology
Great for the ads but for real life the pad on the back much better
Sent from my SM-G975F using Tapatalk
I find it works fine, had no issues using it.
I actually found the pad on the back of my s8 plus to be more of a pain to use so never bothered with it.
S8 yes, I agree
S9 was easy in real life
This new thing is just poorly thought through, tech for the sake of it
Sent from my SM-G975F using Tapatalk
Ah, never bothered with the s9, I'm coming from the 8.
I had bad experience with the sensor too at the beginning but I did the following things and now it is much better... Actually I was hasty to set it up the first time and that was the problem..
1) use the same finger three or four times
2) ignore the indication at the screen about which part of your finger is not scanned and just keep trying
3) the most important is to scan your finger naturally like in normal conditions and not like you try to set up the fingerprint..
4) play with different areas and angles of your finger until the setting up is complete
5) after you set-up the fingerprints there is an option to test them.. Do that multiple times and see which of the three or four is not used. In a good set up all of them should show as used. Remove and register again those that do not appear at all or frequently
Cheers, one of my fingers won't work at all

That sounds like a personal problem. ?
I took the screen protector off that came with the phone. That alone improved the detection. From my experience with fps's it is best to constantly change the angle of the finger until the scan is complete. Also try holding your finger on the fps 1 second longer than normal.

Does your s10/s10+ Fingerprint Scanner Suck!??

Hi, I just want to share my experience with my Galaxy s10's fingerprint scanner. First of all i'm using an exynos galaxy s10 with a whitestone dome glass perfectly installed on it, so far my experience with the fingerprint scanner is awful. It's the thing the makes me rate this phone badly. i'm a person who gets their hands very sweaty often and it made me excited when i heard that this scanner will work even with wet fingers but this is what i found out with my s10's scanner. it works better when my fingers are moist. whenever my fingers are naturally dry the phone will ask me to put more pressure than the usual pressure i give, in addition most of the time it gives me the NO MATCH feedback, to the point that my phone locks itself for seconds because of the repeated failures. when i got my phone i updated it to the latest update i think it's security patch level feb 1 2019. i've tried a lot of method scanning my fingers a lot of times, i've maxed out the fingerprint slots with one finger just so it will scan it more accurately. But it's just annoying there are times it would work perfectly there are times it's awful. i've owned this phone for 4days now and everyday i always register my fingerprint because it's that annoying. How's your experience with your fingerprint scanner? Any suggestions?

Did it work any better before you applied the Whitestone and have you changed the screen sensitivity. I have the Snapdragon but haven't had that much trouble. Since I have trusted places, on-body detection and trusted devices (my watch) on, I almost never have to use the fingerprint except for logging in secure apps and they work almost 100% of the time. I do still have the factory protector installed.
Yes its crappy at the moment. I'm getting roughly 7 in 10 success rate & have to consciously make sure I press the right area. My Oneplus 6T works nearly everytime. Hopefully updates will make it better.
Mine is good but due to the physics (S9+ you simply had a Spot to lock your finger into) it is not as good as S9+.
Personally, I don't have complains when using the finger print on my S10 Plus. I used to use screen protectors on every phones. Now I don't use screen protectors anymore. The screens now days are more durable and scratch proof than people think. Just use it normally and the screen will be fine. The last couple phones (Including iPhones) that I have used has no stretches on the screen after long time usage. Ended up selling all of them as mint condition.
On the S10, the finger print sensor works better without a screen protector. Also, you can register your finger print more than once (Using the same finger) if you need to. Remember to do it with different angles as well.
Finding it very disappointing! Taken off the supplied screen protector and adding a second finger print using the same thumb did help but its still way behind a physical button! My S9 plus was perfection compared to this! I have a success rate of about 6/7 out of 10! I always feel like iam placing my finger perfectly in the right area but sometimes it just refuses to unlcock ha
I hate to big up Apple because i hate them as a company but the iphone xs works flawlessly in comparison and Face id is a dream to use compared to this crap!

Question Fingerprint sensor issues? WASH YOUR HANDS!!!

I've been plagued by fingerprint issues just like everyone else. But I've also been running an experiment. Every time my fingerprint won't unlock the phone I wash my hands. AND IT WORKS EVERY SINGLE TIME!! The sensor is EXTREMELY sensitive!! If you have even one speck of dust it could fail to unlock.
I promise you.... try it!! It will work every single time!!
I mean really, thanks Google!!! I probably should wash my hands more if they're dirty enough to keep the sensor from working.
Helps to clean the sensor now and then, too. I have this issue on my Pixel 5 all the time.
I actually find the opposite. If my fingers have any dampness at all, it won't read properly.
I only wash my hands once a week and the sensor works fine
Do you have any protection applied on the phone ?
Wash my hands? I never had a device with in display fingerprint which needed washed hands.
I just added a new tempered glass screen protector, and that one is known for being awesome. I added all four fingerprints again, and it all worked like a charm for like five hours. 10/10 instant unlock. Today it does not work anymore. 3/10 unlock and slow. It's a software issue I guess and by now I'm totally fed up with the incompetence of the Google developers. It's a 750€ device, and even 200€ BBK phones got better working fingerprint readers.
I'm quite pi**ed.

That happens to me too sometimes. Like perfect for a day or so then no matter what I do it's 3/10 just like you. I then reboot and it usually clears it up. One fail safe method it to rub your thumb (or whatever finger you use) across your forehead then try again. I've heard licking your finger but that is disgusting and I'd never do that. Try those 2 methods see if it helps. The March update also seems to make it quicker but it could be placebo.

I've gone from being pissed to being amused at how bad it is. For me 7 is worse than 6 ever was. Hell, just getting a couple digits enrolled on 7 has been impossible, and for an extra rub it teases and craps out at the 11:55 mark every time.
To be fair, I work with lumber and my digits tend to be rough. But this never stopped me from using fingerprints with older and cheaper phones.

What that means is the fingerprint sensor on your phone is of poor quality, just like some of the other components.
Google Pixel phones and their clean (read very basic with lack of features) software are both overrated and overpriced. You're essentially paying the premium to cover their marketing costs, and not for buying a better device.
I live in a dry environment, and I find that if my fingers are particularly dry the FPS doesn't work. Just breathing on my fingertip is usually enough to get the FPS to work. That being said, the March 2023 update seems to have improved the FPS significantly for me. Or it may be placibo effect.
It's 2:00 AM here, I switched off the lights in my room, took my P7, removed all four fingerprints, added them again sitting in full darkness. Turned on lights again. Well... now the fingerprint reader has never been so fast, unlocking so snappy and even with a soft and short touch with the tip of my finger. Hilarious.
I hope the devs at Google optimize the software for this mess of a sensor. What a sh*tshow.
And now at 10:30 AM it does not work anymore... LOL. No matter how I press the sensor, it forces me to put in my PIN to unlock.
This is weird that some people have problems with FPS while others don't.
I was initially afraid about this FPS issue reading all the bad experiences but it works basically 99% of times.
I still suspect it has more to do how you position your finger on the learning phase and is the finger dry or moist.
Because during learning phase it didn't ask to retouch the sensor with moist fingers but did ask to try again with dry finger. I suspect if you teach with moist finger it expects moist fingers but with dryer fingers it seems to not matter that much. On learning phase i pressed slightly harder compared to normal use.
I relearned finger 3 times because on the first two tries it would work about 50% of times. I remember i pressed quite gently on first tries since it looked like it registered it.
On the last try i had semi-dry fingers and tried to mimic normal unlocking position while giving the whole footprint. Even the very bottom part of thumb that normally don't touch the sensor.
Now it's pretty much like OnePlus6 experience with FPS with the exception that when the finger is super dry need to press slightly harder and it will register it.
If it matters i have screen film applied on screen. Not tempered glass.
Also with March 2023 update i haven't had a single fail yet with fingerprint detection.
Initially when received the phone i had October 2022 software and i didn't want to update. Then i exactly remember that it would stop working normally after a day or so. Like it forgot some areas of finger or expected very precise location.
I did buy phone in february and it could be that earlier batches had different FPS hardware revision. Smaller resolution/memory ... ?
I played around with FPS trying to get it to fail and when pressing too gently it fails so i would conclude the right pressure is quite important. Didn't find any difference in total darkness vs well lit room.

It is a fairly well know thing after Google moved away from the ultrasonic finger print scanners last used on the Pixel 5s, it has not worked well for many people. If you did the research prior you would have seen this has been issue ever since. Easy solution is don't use it and go back to the old style of a pin or pattern.
Can't comment on the face recognition portion, since I haven't done any research on it, nor do I want to, since I don't have a desire to use it, but I am sure other here have extensive experience and knowledge about it. Just have to do the research before trying it if you want to know what may or may not come of it before trying.

Even easier is to not use any protection at all.
Both are impractical suggestions.
Having been spoiled by Face Unlock, there is no going back for me. Fingerprint is used mostly in dark environments where Face Unlock struggles.

and the darkness is where my fingerprint on Pixel 7 fails 100% of the time.
Pin is difficult while in motion. Pattern for me is easiest.
To OP, I wash my hands religiously. I won't touch a door knob and then touch my face, so washing alone is not the solution. I imagine it has to do with screen protectors installed since everyone uses different ones that have varying thicknesses and see-through visibility.

I wonder what kind of special fingerprint sensor the Pixel 6 and 7 have then. My last few devices (Realme & OnePlus) with in-display fpr ... well you could have slapped a $2 or a $50 tgsp on it, and it did not matter in any way. They worked just like a charm. I had a Pixel 6 (yeah, f* that pos) and now a Pixel 7 (I really like it) and both fpr are the worst mess.

You gotta figure out what is wrong. Not too many responses here because most are not having those issues any longer. Originally, yes for sure. But lately it's been working a good 90+ % of the time. Never can get an unlock after swimming though until I moisturize but that's excusable. Get rid of the silly screen protector which is useless unless you are in the sand/gravel business which I see you are not. (nice walls) If it still doesn't work perhaps an RMA would be in order. I've seen that happen and the replacement is way better. But you shouldn't live with a flawed device that is otherwise very good.

All good points. I don't have opinions about which screen protector works best since my Pixel 7 sensor is a dud without one. If my 7 is worse than 6 then simple logic suggests there's a defect.
I bought a used Pixel 5 a few months ago as a backup, plus it helped verify my P7 problem isn't my fingers. My wife called the P5 "cute" so now she has it. I've never gone through Google's replacement process before but it should be a breeze compared to getting the P5 back.

One of the issues seems to be Tensor/Exynos versus Snapdragon. Apparently, the former can't use the latter's ultrasonic sensor tech without infringing on patents. But I think the overwhelming problem boils down to tolerances and inconsistencies in the manufacturing process, especially in the past couple years, and whether our Pixels were assembled during first shift Monday morning, hump day, payday...
@manjaroid lol you have no idea what it took to get my wife to trade in her p5. The p7 cost $100 after so she went for it. Of the rumors of the p8 at 5.8 are true then Black Friday is looking really good. As for your device it does sound like a lemon. Try to get an rma of you can.
