Fingerprint not-so-safe? - Galaxy S6 Q&A, Help & Troubleshooting

My S6 recognises both of my thumbs even though I have only put one in... Even when I removed the print and tried again it still allows both of my thumbs.

That is definitely strange. If resetting to stock doesn't fix the problem, I'd pronounce it defective and take it back.

Do i need to replace the LCD on my sensation?

Hi,
My phone fell earlier today and i think it may mucked up the screen, see at the attached screenshot, the strip on the left hand side is not working anymore, any ideas on what I should do

Your LCD is fine anyway so if it were me i would take the phone apart and check if the Digitizer flex cable is still connected properly, might of come loose after dropping it. If it is still connected and all seems ok then u will prob need to replace the Digitizer.
hmm, the strip seems to work a few times, then it doesn't respond
Another thing that i have just seen is that when i i go into teh app drawer, it automatically goes to the widget tab, it seems that the screen is constantly being touched where the widget tab is

flex cable might just be loose. take the phone apart and check connections, its not that hard, plenty vids on youtube.
Thanks, I'll give it a go.
I've attached another pic of where the touch seems to be stuck. All I did was tap on the screen.

Nexus 5 wont turn on at all :(

So i dropped my nexus 5 from about 2 ft accidentally and now it wont turn on, and it is extremely hot. Please some one helppppp!:crying:
I don't think it works, but please test it: Press and hold the powerbutton for 20-30 seconds. This will preform a reset (like removing battery). Good luck!

If it is getting hot, it's probably turning on. Looks like you'll have to get your screen replaced. Even if there is no crack, it does not mean the screen and digitizer is still intact.

extremely hot means something wrong with the devices including system corruption, if its hardware problem u might want to send to phone shop for diagnose,, if its software, try flash stock rom.. sees if its boot and showed up boot image...
i hope it doesnt have hardware damage since just a 2feet drop,, nevertheless the digitizer screen

I cant get into bootloader so i cant flash a factory image, there is no haptic feedback too. So i guess its a hardware problem.. the phone has cooled now. But it was extremely hot for an hour. I guess the battery ran out.

If by can't boot into bootloader you mean all you see is a black screen. Well that pretty much confirms that at least the screen needs to be replaced. Get it replaced and when testing it you'll find out if there's anything else wrong (hardware wise) with your Nexus 5. Cheers.

Yes , but if it was the screen, atleast i would've got some response from the phone, such as the charging light or atleast i would've been detected on my pc. Oh well, anyways ill have to get it repaired.

Nope. i got it checked and its the whole motherboard. Now i got to buy a new phone. Still confused how a 2 feet drop did this..
I can say that the body can't holds up that figure impact, our n5 is a whole plastics haha... My fri3nds n5 dropped his at 5 feet from his bare hands on a carpet, guess what, screen broken and its frame gone loose,,, wow, nice build.... However nexus 5 rocks !!!!
I recommend removing the back cover and checking for loose or damaged connections. Also, remove and re-attached each connections and try to boot the phone.

Multitouch not working

Not more than 2 fingers are being recognised by my sprint note 5, any help?

So out of curiosity. First things first
Do u have a case on it and tried with it off?
Do you have a case with a plastic screen protec and or a temp glass. Try removing those some thicker temp glass interferes with operation.
Third. Have u dropped your device?
4th. Are you rooted and made any mods to the system. If no to the cases and glasses and yes to rooting. Try reflashing stock firmware. And then try.
If not rooted and or dropped. Sounds like internal malfuntion. Nothing here will fix that.
U might try looking for a touch sensativity or accsesibility setting or something allong those lines.
What firmware custom roms anything like that?

Well i do have a case, i removed it to check but it still didn't work. I reverted back to stock unrooted. I did drop it and cracked the glass. I had the glass replaced but i didnt noticed the fault until recently. My theory is that as it fell, the connectors on the digitizer came loose.

That is a possibility. I did some work on mine and didnt get the usb home and touch buttons plugged in all the way. The light doesnt work on my recents key and randomly went nuts til i checked it and it was barely plugged in. Just enough to work.

Then ill have the phone checked out. I really dont believe the digitizer is damaged. The fact that only 2 fingers register may really be because of the connector. Thanks for the help

Having problems with fingerprint sensor

Sometimes the sensor doesn't read my fingerprint for 8-10 times. Just keeps vibrating. I need to hold and press my finger dead centre to unlock. Is that how it actually works? Although sometimes it unlocks even just a partial touch. Also sometimes it doesn't respond at all. Is it a hardware problem?

maybe you set up your finger wrongly. try setting it up again. my fingerprint sensor works 99% of the times from the first time.

Yes maybe you did a faulty first setup. Set it up again but very careful this time.

I have deleted and setup the fingerprint multiple times. Each time it works for one or two days flawlessly. Then starts giving problems. Especially when running music player, it'll will never read. Well, I think I'll take it to the service center when I have time as the service center is in a different city.

I didn't get to go to the service centre. But i resolved the problem. I just added one more fingerprint of a different finger and now it works all the time. And is fast too. Don't know what that's got to do with that.

Yeah it is strange. If I delete the second fingerprint. It becomes problematic.

I made a setup for both left 'n right fingers too, because i've noticed from 1st day that when i was using the finger used in the setup there was no problems unlocking phone, meanwhile when i was tryin' to unlock with the other one my phone was just keep vibrating as yours. To me this is not a defect, but a clear sign of an even more accuracy placed inside this sensor. Think about it; your left fingerprint isn't the same of the right, because it just CAN'T be equal to the right one! So even if some line could match the other finger, the sensor detects a difference between one and the other and avoid the unlock. I registered my 2nd finger happy after that i thought this
Try to register the same finger twice with evwry different agnle. It will work almost ?% times
man i'm experiencing this too! but the difference is our phone. mine is honor 10 but like i've said i'm experiencing the exact same issue!! tried to do full reset still not working. i even try to register my first fingerprint data but no result. strangely, when my phone is off, and i tried to use the fingerprint, my phone was woke up! i do not understand what kind of bug is this but hopefully as the time goes it will resolved itself:angel:
I have problem with my finger print sensor of honor 6x sometimes it works or sometimes it doesnt show the option of fingerprint, when it doesn't show it messege hardware is not available tell me the solution.

Before the solution it'd be useful to know if this is an hardware issue or software one. Can you tell more about? Problems began after some drop to the floor or normally from one day to the next one? Stock or custom ROM?

Dual Screen Cover not working.

So out of nowhere the second screen doesn't turn on. I can still do gestures and move apps to the second screen, but the screen is completely off. Anyone encountered this? I turned off and on, I updated the firmware through the hidden menu, I force closed the dual home app and still nothing. Help!?

Check out the 3 pins on both parts. Also did you do some changes in connectivity, wifi? Wifi Direct or screen sharing. Because I highly doubt the information and power are being transmitted only by 3 pins! Seems impossible.
Were you messing around with, like, kingoroot or anything? Any recent updates you've done to the device? Any drops or impacts to the device, or left in a pocket and sat on, left in your pocket and your pants dropped to the floor? Caught in a downpour that soaked through your pants? The LG V50 is supposed to have good water resistance, but I'm not sure about the dual screen accessory. And chance it got wet?

August 29th update. I really don't know what happened. I'm using a regular case untill I figure this out.
Like I said, I updated the second screen firmware and still nothing. I don't want to do a factory reset, but if nothing else works I'll have to do that.

For sure factory reset and WIPE cache. I,ve put the LGUP 1.16 and commond dll installers.
I,m buying another V500N this time with dual screen for a friend. The dual screen is for me. Also go for 2 back glasses gorilla 6 for backup. $12 on ebay/piece is a bargain.

Hello, Dathaniel.
https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/273971456048
Awesome, thanks.
If you're the type that the Dual Screen is calling to, rest assured, you're going to love it. It does feel a little prototypey, but I'm glad to see LG is still pursuing the form factor. I'm fully expecting the hype bubble around foldables to burst once people realize that the tech is an actual hindrance to productivity, and I'm hopeful that the dual screen implementation will take off instead.
That the V50 is confined to only 6gb/128gb memory, and lacks UFS3 are its only major trailing factors, but don't present any problem at current. Even faster charging options, reverse wireless for earbuds, and a depth sensor would be nice frills, but the wide angle selfie, the boom box and quad DAC more than make up for it. I do miss the ePen of the note, and can only dream at present of a Galaxy Note Dual Screen.
But I say, DO IT! The V50 Dual Screen is, even with price not considered, in my estimation, the best smartphone available in 2019. You'll love it. It changes everything.
Looks like this rom does not support. Dual screen icon was blurred.
(V500N Korea version U +)
Do you have any solutions that can help?
Thank you.

I have the (V500N Korea version U +) and it works good with the Dual screen. But i notice in your photo you have the screen folded all the way back ! This turns the screen off, and blurrs that dual screen icon (like you circled)
Open the screen up and and it should un-blurr (if that is a word).
(You may have worked this out already as your post is 1 1/2 months old now)

Same problem.
The case which holds the phone was loose. I nudged it with a piece of paper at both bottom part and now its working.
