Galaxy S10+ face Recognition Hack! - Samsung Galaxy S10+ Guides, News, & Discussion

hello . i was checking my cousin's s10+ comparing it with note 10+ and when i press the power button his phone displayed the icon of unlock its a hack . phone is running latest security patch October 2019 and you can only register one face on this phone as you can see in this video i can able to unlock his phone multiple time . i tried it on note 10+ too i worked 3 4 time on note 10+ 5g too will post the video of note 10+ too but in note 10+ its hard to get in and in s10+ its real quick

How exactly it's a "hack"? It's working as intended. There is an option in the settings for faster unlocking and it displays warning that it's less secure because you would be able to unlock the phone with slightly similar face or even a photo/video of the person.

[Solved] Galaxy A3 2017 - fingerprint scanner almost unusable

Hello,
Anyone else has this problem where the fingerprint scanner barely works (almost unusable) ? I tried many ways to enter the fingerprints but it registers like 1 in 10 tries...

If that does not solve the issue, also try this:

same here. Samsung makes the worst finger print scanners.
thinking of 4 scan for same finger see if that helps.
Huawei makes the best finger print scanners

That is not normal, my A5 works 9 in 10 on the first try.
Not a single error in my A3
Mine is totally unusable... any idea?
Well, it seems that I'm not the only one with this problem. Hopefully it can be fixed with an update.
I have to say that my thumb skin is a bit damaged (from doing work on cars, around the house, etc.) but this was never a problem with my S7 Edge. I tried a different finger with healthy skin and it does work a lot better, but still not 100%, it seems to me that the A3 sensor has real issues.
same Problem with my girlfriends A3.
Fingerprint scannner works in 1 of 4 times if youre lucky sometimes doesn't work at all.
She has already made 3 scans with 1 finger but didn't really help
Maybe send it back for warrenty repairs if a factory reset won't work'? I'm sorry but fingerprint sensor should work fine.

To be honest, I don't think this is solvable via warranty work. I am not sending my almost new phone back just to receive a refurbished piece of thrash. I am putting my faith into a firmware update. The funny thing is, I really like the phone even with this problem, it is very fluid and has even better battery life than the S7 Edge.
So here is a workaround I have found, for those having the issue:
- Instead of using the tip of the finger when adding your fingerprint, use the area just below the tip. In the attached picture, use the area marked with green instead of the one marked with red. It will then work 100%, it's amazing how fast and accurate it is. It's just not very smart like the S7/S8 and other phones and it probably has issues when the skin is not 100% perfect or maybe with pronounced geometric distortions like it is the case when using the finger tip.
Hi folks, a workaround for me was disabling the keep screen turned off, became much more accurate after that
I've got similar problem with always on display. When I turned it off everithyng is fine
I am having similar issues with my phone. I have tried using all three stored fingerprints as just my thumb and I still have trouble getting it to unlock. I do have Always On Display turned on, and I don't really want to disable it as suggested in this thread because it's an awesome feature. Samsung should be able to something as easy as a fingerprint scanner right. Hopefully this is simply a software issue that is patched
hi guys
you lock phone with power key or with widget (like screen off)?
After having the same problem I started turning my thumb much more (even almost fully vertical) during the scanning process. Now it works fine. DHNL
hi actually solved the problem what i did is that factory reset the phone, i schedule a weekly restart, i clean my scanner and i assigned all 3 fingerprints on to the same finger and it worked
Hi folks,
I am experiencing the same issue. I found some relief using a different finger. I have registered three of my fingersprints. For some weird reason only one of the three fingers works acceptably good, the other two are successful very rarely. I therefore recommend you to try with a different finger or several of them to find out which one better works for you.
Good luck !
I can confirm there is indeed a problem with SAMSUNG A5 2017 fingerprint system. The recognition rate can be extremely low in some condition (around 10% positive, meaning almost unusable). This seems to be a software bug
Here is a turn around :
If you record your fingerprint with the screen "always on" function activated , then the recognition rate is extremely poor.
if you unactivate this function during recording process, then the rate is ok (higher than 90%), even if you reactivate the always on function after recoring session
I guess this could be solved by Samsung in the latest firmware A5 (2017) update.

Finger print and Face detection issue with A50

Dear Friends
A50 current version A505FDDU1ASE3 / A505FOJM1ASE2 / A505FXXU1ASE2, Security patch level 1 May 2019
The issue: very slow FP reading plus Face reading is not good, it can open the device with eye closed face, even with the diagonal angle too, which is dangerous, it means anybody can unlock your phone while you sleep.
I have logged the call with Samsung support and they advised to upgrade to the latest version through the phone, which I did. and asked to delete the registered FP and Face, and re-register it.
I did, the problem remains the same... anybody found a similar issue?
FP reader posts are dime a dozen in this forum. To provide my opinion, the FP reader was extremely poor in March, significantly improved in April and now seems to be working at the level allowed by the hardware.
It takes less than a second to completely unlock using the FP reader, but for that you have to register your FP in the various positions you would normally unlock it and then make small adjustments. Don't follow any guide telling you to register using specific movements. This is what works best for me.
The Face Unlock is extremely insecure as it unlocks with photos and closed eyes. It is there only for convenience.

I have been facing the same issue. I got my phone on my birthday in March month; I was excited about the Samsung A50 device, but when I set the screen lock using fingerprint, it gives delay. Also, I have the latest version of Android 9. Still, it troubles me.

Samsung pay

I've had my unlocked note 10+ for a few weeks now. I have it flashed to tmobile firmware and it's been working great. My issue is with samsung pay and my gym membership. I came from a note 8 and my gym membership is a bar code which worked with the gyms scanner. When I switched over to the note 10+, the gyms scanner wont scan the bar code anymore.I've called Samsung and they said it's a first for them. They had me clear the cache and re-enter my card, both of those attempts didn't work. Has anyone had an issue with this?
any insight?
Anyone?

When you say barcode that is read by the gym's scanner is it a barcode that is displayed on the screen, and you hold the phone up to a reader for it to scan that bar code from the screen?
If this is the case then there is really no answer.
So in order to get this to work you need to adjust the screen brightness up and/or down, angle of the phone (when held up to the scanner), distance of the phone from the reader, zoom in or zoom out on the bar code (if possible), and make sure the screen is clean.
It's a lot of trial and error until you get it to work, no magic one size fits all cure exists. So all, one or a few of the steps above will help.. You will just have to experiment until you find what works for you.
I had a similar issue (barcode scanning from the phone's screen) while using a store gift card via bar code on the screen of the phone. That's all I did (the things I mentioned above) to get it to work, but it did work eventually.

yes correct. ive tried moving it around, up, down, tilting it. tried moving the distance.
when i go to the card, the screen does brighten up a bit but not to full brightness. i guess ill have to try that. with my note 8 it never went to full brightness and still scanned pretty quick. thanks for the input and ill post up after i try putting the brightness up all the way.

I would avoid comparing the two phones like that, they are obviously not the same. If they were you wouldn't have to go through this much effort.
You will have to adjust the brightness manually (in case you haven't already). With scanning a barcode off the phone don't rely on the phone's ability to auto adjust based on your previous brightness settings for the level of light present.
Do you have screen protector? Perhaps different phones/screen protectors have different reflection levels.

Every morning I must use my PIN to unlock my s20+

I previously had a Galaxy S9+ (android 9).
I wirelessly (and wired) charged it overnight.
In the morning, the fingerprint reader would unlock the phone - no problems.
I (only) ever needed my PIN to unlock it after a reboot, or after what "seemed" like many "days" of use.
Now, I have a new S20+ (android 10).
Every morning, after wirelessly (or wired) charging overnight, the phone forces me to use my PIN to unlock it.
There has been NO reboot. The auto-optimize and auto restart are (not) enabled.
Is this forced PIN unlock requirement normal behavior - or is there a setting where I can change this ?
I am half-asleep in the morning, and would like to be able to use my fingerprint to get into my phone - as entering a PIN is annoying and slow.
I have searched around for an answer to this and have seen all kinds of conflicting information - but none relevant to what I am experiencing.
I have seen: PIN unlock needed if --> reboot, or 72, 48, and 4 hours of non-use, or xxx number of fingerprint unlocks, etc.....
My case is simply (overnight) - which is 7 hours, max - so this makes no sense.
Obviously, on Android 9 with my previous s9+ this was not happening.
Anyone have some ideas on this ?
Maybe it's auto restart...
Check under advance menu in device care and uncheck it.
My auto reboot is set during the day but I noticed it rebooted over night so maybe its something else.
I know you say auto-restart is disabled but maybe you can check the battery usage graph and see if your phone did in-fact restart during the night. Maybe due to a crash/bug.
Other than that I'm not sure. And FYI this is NOT normal behavior. I haven't had to use a pin on my S20+ to unlock it a single time since initial setup on day 1.
Hi, hope this answers your question.

i believe new samsung policies is now asking for pin to be entered every now and again but shouldnt be so often - i get it like once or twice a week
Innit
Wonderful.
Thanks for that !
Indeed that is exactly what seems to be going on.
I use both face unlock and fingerprints.
From that document you linked, it is obvious that when my phone is idle for 4 hours while I am sleeping, that because I use face unlock, it makes me use my PIN to unlock it
I surely do not like this behavior/rule, but at least I now have the answer to what is going on.
You just saved me the hassle of doing a factory reset !
Tonight, I will remove the face unlock completely and test this to see if I am required to use my PIN in the morning or not.
I will report back here what happens.
This is a great topic. I was just wondering this AM why I need to keep entering in my code every morning.

Nice find! Thanks
I've noticed this also.
I just wanted to confirm that last night I removed face unlock and this morning I was able to unlock my phone using my fingerprint without the need to use my PIN.
I definitely preferred the quickness of face unlock versus the awful fingerprint reader on this phone but at least now, when I get up in the morning, I can easily get into my phone without having to enter a pin.
Thank you so much for your assistance here.
Innit, by the way, where did you get that information from in the first place ?

Loading oem pixel platform to s20

2 week old s20 ultra, my first samsung and I heard someone say you can either have good hardware with garbage software (samsung) or good software with junk hardware (google pixel) and I'm finding that to be very very true.
My past (pixel 2) was very intuitive, the samsung not so much.
Issues I have so far that I would like to correct with using the pixel rom? Is that the right word?
Having to hit the power button then the volume key to snooze the alarm because the volume keys aren't enabled when the screen is off?
A giant empty lock screen with no easy options of going to the next track or pausing different media sources without scrolling through them all.
Bixby is worthless.
My power button doesn't act as a power button
The OEM pixel messages app doesn't work properly on the s20u, freezes when launched and eventually comes back.
At a glance works most of the time.
You can't easily copy of phone number with the samsung dialer. Only (delete) that's it
Can't easily report spam calls (I get 7+ a day)
All of this seems trivial to my girl, saying I need to get used to it, but it's like taking 2 steps backwards in the software world.
Any opinions on getting rid of the stock build? It's driving me insane.
Sorry for the long winded post. Thanks in Advance!

Surely you should have done some research about samsung one ui before you start complaining. Why dont you try to adapt to what you have. You are best suited to stock android so maybe the pixel is for you.
Failing to adapt try this link.

It would appear finding versions of messages etc that will run on this oem software is my best option.

No such thing as a "perfect device". If you didn't research the S20 prior to purchase why complain now? Did you opt for a Carrier Branded device or is your bootloader unlocked? If so you can modify the OS for some desired adaptations. International variants are better suited for a cleaner android experience. The S20 has numerous advantages over Pixel devices. Display, battery, internal memory, better processor, 5G capability, cost is comparable and the cameras with all features considered is on par with Pixel 4 XL. Skin on the S20 has improved since TouchWiz but it isn't pure android for better or worse. Your hope of merging the best of both devices for the most part isn't an option.
