Fingerprint scanner ghost touches my screen - Xiaomi Redmi S2 Questions & Answers

So in every custom rom I've installed if I touches the fingerprint scanner even though it's not the finger I've registered it touches the screen. I don't know why it happens but it always select the first option if there's multiple. I never encountered this problem within the original ROM.

Lockscreen Bug

Can anyone confirm whether this happens to them. I have fingerprint lock with either a pin or pattern as backup.
If on the lockscreen I swipe the screen rather than use the fingerprint lock the pin/pattern screen comes up with the blurb "Use Fingerprint or draw unlock pattern" However when i then put my finger on the scanner it doesn't register, its as if i haven't put my finger on the button. The only way I can access is via inputting pattern/pin. Once i have done this i can repeat by locking the screen and swiping and the reader registers.
However if i leave the phone for 10-15 minutes it then goes back to not registering the fingerprint on the pin/pattern screen again?
Anyone else getting this?
Getting the exact same issue on the Galaxy S7Edge with Australian firmware, and it completely ruins the usefulness of the fingerprint unlock method.
It's definitely a bug in the software - a few people have already experienced the exact same issue we have encountered over at:

Hopefully Samsung are at least aware of the issue and can patch it..
I had something called lock screen launcher or something like that I did uninstall it and it was normal again

Fingerprint unlocks phone while in the pocket

Hello,
I've recently discovered that if you try and place a finger on the fingerprint sensor while the phone is in your pocket, the screen will successfully unlock, which I believe it's not normal behaviour. Every time I pull it out of my pocket the screen turns on and the phone unlocks, leaving it prone to accidental taps and inevitably open random apps every time.
Does anybody else have this issue?
I just tested it. Same here.
If I cover the sensors while the phone is just sitting there and then place my finger on the fingerprint reader - it registers it and unlocks the phone.
If the phone is unlocked and I cover the sensors - I get a message that the touch protection is active and it doesn't allow me to click on the screen.
Great "touch protection", Huawei. Good job on this one.

Yeah, it basically works only once the phone has already been unlocked, lol.
Nice addition to the stupid lock-screen notification issue we are having in the other thread. How awful.
At least I'm glad I'm not the only one, I'll try and open a chat when I have some spare time to waste...

OP 6 Automatically unlocks

Hi,
I have a problem with my OP6. I hae the latest OOS 5.1.11.
When I have the phone in my pocket, it's locked, than quite often when pulling out of the pocket I naturally grab it the way, that mu thumb is in the screen (I am not touching the fingerprint sensor) and when I take it out of the pocket, the screen unlocks itself.
Is this problem related to the issues people have posted regarding pocket mode not working and allowing to unlick with fingerprint while still in pocket or another bug or maybe hardware issue?
Thanks
face unlock??
No, its even before it's able to "see" my face. I just feel a small vibration under my finger and it unlocks. Also, for face unlock to be activated I would need to wake up the screen, but the problem is, it wakes up on it's own.

I think you have enabled the 'double tap to wake' option. Sometimes when you hold the phone and touch the screen, it recognizes it as if you double tap it, and then face unlock kicks in. I personally have enabled an extra required swipe up after face unlock to unlock my phone as a solution.
Yes, I have been using double tap to wake, and everything was fine, as I have the phone since the launch. I have started noticing the issues recently. Also, if just touching the screen activates the "double tap" then obviously something is not right, because it happens quite often. I have disabled pocket mode for now to see if anything changes.

(Weird issue)nord touch not getting registrered, but fp unlock/screen shot/recent draw working.

I am facing this super weird issue with my one plus Nord. it seems like my screen is not working as any of the swipes/touch etc or anything is not registered. but I am able to take screenshots with 3 finger gestures, I am able to unlock the phone with fingerprint with fp scanner, and once I'm unlocked I can only perform the recent tab open gesture(swipe from bottom)...
except for these 3 actions, nothing else works.
And the most astonishing thing is the power button is also working as a 1-second press. meaning I am able to lock/unlock the screen, but I am not able to force restart the device, that's right; if I try to click the button for 10-20 seconds, the screen just gets locked/unlocked as if I pressed it just for 1 second.
This is super random and I have no clue how to fix this issue, as I am not even able to restart/reset my device.
I am just now stuck waiting for the phone to get discharged and then I can try resetting by recovery. anyone has any solution or has anyone faced this after the recent nord update?

Question Fingerprint scanner issue, s22 ultra

my touch screen stops working from exact fingerprint scanning area,then i have to press lock button then unlock by finger scanning, and it starts working again, it happens very frequently. its very annoying it doesnt let me scroll the web page, facebook or twitter, whenever my finger reaches scanning area either it register a click and opens the link or it does not scroll, again i have to do locking unlocking and it works fine again. restarted my device, wipe cache partition, but couldn't solve my problem.

Do you have a screen protector and if so what type
Yes , hydrogel screen protector.
Then possibly it to blame
But it works fine after locking unlocking,may be its a software bug
