Fingerprint Scanner Problem in 6.0 MM - LG V10 Q&A, Help & Troubleshooting

Hi guys!
I really love this phone, but I have a really, really, really annoying bug. I have only 2 days with this phone (MM updated since the first day). When I try to unlock with my finger it works most of the time, but in some occasions it ask me for the knock code or the pin directly, giving me no chance to use my fingerprint to unlock the phone. This is really annoying because I want to use the fingerprint sensor to unlock the phone and it does not let me. Does anyone have the same problem with the V10? Any ideas for a possible solution? Thanks a lot!

We have this problem too and assume you are using a third party launcher (Nova, Google, etc). Switch back to LG stock launcher and it fixes the problem. Think it has something to do with the lockscreen permission changes from Lollipop to Marshmallow.

I'm actually using Nova. I will switch back to LG Stock Launcher (uggly, by the way), and I'll tell you if it worked or not for me. I'm thinking on the same about te permissions in MM. There is no way to upgrade permissions from the settings or something like that to keep using a third party launcher?
Thanks a lot for the help!

I ran with LG's launcher for the past couple of weeks and since the recent beta updates to Nova shows no sign of a solution, I've reverted back to Nova and just switched to pattern unlock for the time being.

You know, even using nova, you can double tap the notification bar to turn off, and still use the fingerprint to unlock.

^ Incase anyone of you missed it, the finger print scanner works if you double tap the notification on Nova Launcher to lock the screen.

Try to factory reset, or change the unlock method to a different one, and then go back to fingerprint.

already did.factory reset by lg bridge..hmmmm
. i do hope its only a s/w issue. huhuhu

may due to mainboard problem
i also met this problem.
after restart, restore or refresh kdz, nothing changed...
my model is LG V10 H961N

Speak for yourself. :laugh:
I'm on MM on my H960A AND I'm using Nova Launcher since the first day. Never had this issue. I only had a problem once after unlocking the bootloader. You have to enable "OEM unlock" in the developer settings prior to unlocking the bootloader and I did not disable that option again afterwards. The fingerprint sensor did not work at all with this setting enabled. You can register new fingerprints but unlock does not work.
Since I disabled this option I have no issues with Nova and fingerprint. Should you have unlocked your bootloader as well make sure you disable "OEM unlock" again.

I'm on MM and using Nova prime but I don't have any problems with the Fingerscanner!

Hi!
I have this phone for 4 days and i had the same problem like you,
I use to lock my screen with third party applications like:
Greenify or Screen Off and Lock
And for this i have the same problem like you,
If you had the third party application for locking your phone, you can uninstall them or lock your screen by double top or power button.
Good Lock!

Try this...
I've had this problem also. It seems to have started after a security update from T-Mobile.
Try this fix and let me know how it works for you:
Follow these steps:
1)Goto settings -> fingerprint & security -> fingerprints -> then delete all fingerprints
2)Then goto apps -> switch to show system apps(im using 6.0) -> find com.lge.fingerprints then remove data and cache memory.
3)Goto storage & usb -> clear cached data
4) Then restart your V10
5) After that, add fingerprints in fingerprint lock then it detects your finger.
If it doesn’t detect your finger, repeat the steps.

You may have to repeat this process as sometimes, I've heard, the problem reoccurs.

[Q] No Lockscreen on my 3VO?

Edit!
I fixed the problem. I was going over my apps and their settings and I noticed that one of them,battery indicator pro had a lockscreen off feature which was flipped on. Totally weird! But I have my lockscreen back! Woot!
End edit :-D
Out of curiosity, has anyone else experienced this?
My 3VO's Lockscreen has disappeared. Legit.
When I press the screen lock button it simply doesn't. It turns the screen off, but it doesn't actually lock the phone.. as a consequence now the phone will do random things in my pocket and its annoying as hell.
I've tried a number of things to restore it just short of a full reset. That I'm trying to avoid because I use this phone as my main one and to restore all my setting would suck major ass.
Please someone shed some light on a solution for me?

Have you rooted and frozen some of the HTC APK's? (There's one for the lockscreen, I'd imagine) That's what it sounds like. If not, I'm not exactly sure what you can do aside from a factory reset...

I haven't even touched the whole perma-temp root thing. When we get permanent root then I'll crack this Guy open. But till then.. I'm not interested in it. Besides I actually like the sense 3.0 locksceen.
I seriously hope I dont have to factory wipe this thing. If i tell the phone to use apassword or pattern or pin code to lock up then the screen comes back .. but that's a pain in the ass to always unlock the stupid thing

The lock screen...

So I've been trying to figure out how to get rid of my lock screen...I selected the option to have no screen lock in the settings multiple times though it still prompts the lock screen...I use goexplorer...is that making it still lock(The lock screen is the stock version, not golock or anything)?
Yesterday I switched between sense and golauncher and for both selected no lock screen in the settings, though that still didnt work...lock screen still present.
any idears? Also, is there a way to get pandora planted on the lockscreen...I remember when I was testing the beats with the stock music player, you could change the song and so on from the lock screen...that was nice.
Try WidgetLocker.....it's not free, but it's great.
Oh thanks for the recommendation though I'm trying to get avoid any lock screen, so I can check my phone without encountering the lock screen

I don't think it can be done.....good luck though.
Pretty sure you can, maybe you can see if it works on your phone?
Settings>Security>Set up screen lock> Select "None"
I cant remember if it worked when I first got the phone(when I didnt have goexplorer)..the nexus has the same feature and it was great not having to unlock it all the time...I just dont wanna hafta uninstall the goexplorer and loose all my settings :/
Nearly impossible unless you are rooted.

all that does is remove any security from the lockscreen (pin, pattern, etc), not the lockscreen itself.
Hmm I'm waiting to root after the ICS update...did it not work on your phone(going to the settings and changing the security preference)?

That takes away the pin or pattern screen, not the lock screen with the ring.

I use ADW, and when I have my NoLock app widget set to Unlock, I get no lock screen. When I turn the screen on, it goes straight to the last screen I was on.

does No Lock not work on the rezound? (Though I would assume it uses the same logic as the GO widget...)

[Q] keyboard stays on when screen is locked

Been having a problem since updating to the 6-25 build of GPE rom. No matter what keyboard i choose, if it was open before i locked the phone it remains open on the lock screen and makes unlock pattern super small and hard to use. Has anyone seen this?

If you're using any xposed modules deactivate all of them and reboot. At least then you can rule out xposed as being the culprit and report the bug to the ROM dev. Maybe even grab a log if at all possible at that point.

Thanks. Turned off gravity box and no more keyboard problems. After restarting it it's still fixed.

Fingerprint unlock loads random app

Hi all
I'm very satisfied with my S6 Edge (925F) but I'm facing a weird problem: when I unlock the phone using my fingerprint(s), it works perfectly but sometimes it's not the home screen which is displayed, but another random app, (i.e Facebook, Settings, News Republic or other...)
I have to press the back button to return to the home screen...
Anyone having the same problem? (not a big deal but...)
Started to happen to me as well a couple of days back. It's strange because it never happened before and I didn't change anything on the phone.
Never happened to me so far. Are you sure you weren't already in that app when you locked your device? The fingerprint unlocks into the last open app. Go back to home before locking.
Another possibility is that you are tapping a notification before unlocking. Say you have a notification from FB and you tap on it. The screen will stay locked, but it will open the FB app. Unlocking with fingerprints will then show FB open. Same can happen for email, texts, etc. You can also pull down the status bar and tap settings, then when you unlock, settings will be open.

Thanks but not at all.
It happens randomly, either I'm in an app or not (and if so, it's not necesseraly the one I was on!)
Quite mysterious...
I was using Nova Launcher (maybe the cause), will give 2-3 days Touchwiz a chance, and will report back...
Hey guys,
same problem for me. It is not dependant of the unlock method (i'm experiencing it with finger print or regular unlock).
I think it is a Nova launcher bug, only occur with nova for me.

I think so...unfortunately...
I think it's the latest nova launcher beta version that causes the issue.
I'm using Nova since I got the phone, a month ago, haven't experienced this.
I have been having this problem too and was about to start a new thread. I am using Nova too, though I did try installing the google now launcher and seemed to have the same problem. I suppose Nova simply being installed may cause the problem.
I will try uninstalling Nova and use TouchWiz for a bit. Not sure how long I will last, I think I prefer the random apps to Touchwiz.
How did the rest of you get on after switching away from Nova?
I have been experiencing this issue as well but ive been using the nokia Z-launcher. I have a feeling it might also be my fingers inadvertently touching the curved portion of the screen when i hold it.
I have the same thing happen to me. I thought I was going insane. The worst part is, I'm on a note 3 and I'm using touchwiz lollipop. I'm 100% sure no applications are running before I lock the phone, and when I use the pattern unlock, whatever application shortcut that was on the screen when I lock the phone, a random app from that screen will run when I unlock the phone. It doesnt happen all the time, but it happens at least a couple times a day.
Reason
Hey guys. I am using Nova Launcher too. And I have the same problem. I don't have the sollution, but I found the reason. ? When you lock your S6, the touchscreen stays for a second active. And if you hit an app in that second it will open when you unlock your S6.
Sorry for my bad English, I hope someone can do something with this information.

It seems that if the Nova's desktop margin is set to "Medium" or "Big", this problem is reduced, but I don't know if it's fully solved. Will see...
Have you found any other solution?

I think that has nothing to do with it. It could be true that it reduces it, but the only reason it would do that is because:
Mostly when you lock your S6 your fingers touch the side of the screen.
When you set margin to "Medium" or "Big" and you lock your phone, your fingers wil most likely touch no app on the side of your desktop, because the margin "pushes" them to the middle of the screen.
I haven't found a solution. Still waiting for an update to fix it.

Yes, that makes sense. Anyway, if looks perfectly good with marging set to medium, and I've had no issues with this problem since I changed the setting (yesterday). So if it reduces the problem so much, I can live with it...

Unlock lag, unlocking takes long time.

Hi.
I was looking for solution, but without luck.
My LG G5 need about few secounds to wakeup, doesn`t matter that i use fingerprint, lockscreen button or double tap. But when i unlock it finally, next quick lock and unlock is ultra fast.
It`s a hardware issue?
Thanks 4 help.

Sometimes my lockscreen "crashes" , gets black and restarts. I think its more like a software bug.

I remember seeing that asked before and someone said if you change the lockscreen image the lag disappears - even if you change it back to the same image.
had the same problem and finally solved it. Do not disable preinstalled apps, like Evernote. After enabling this aplication the problem dissapeared…
