Being flashbanged by my fingerprint sensor (sh.itjust.works)

Hey folks. Got a pixel 7 pro, and it's been alright, except suddenly, if I press the fingerprint sensor on the lock screen for just a split second, it makes the WHOLE SCREEN go full-brightness, with a green tinge. I know it's always lit up the scanner area, which is all it lights up if I hold the sensor, but if I release it early it's actually very uncomfortable. Any suggestions besides the obvious "don't let go 5head"? Is this an android version bug, a hardware issue? Anyone else had this happen?

Just close your eyes 5head

[–] [email protected] 20 points 1 year ago (1 children)

Aw heck, I hadn't thought of that.

[–] [email protected] 12 points 1 year ago (1 children)

Happy to help, my friend

[–] [email protected] 6 points 1 year ago

It worked! I'm not blind this morning!

[–] [email protected] 17 points 1 year ago* (last edited 1 year ago) (2 children)

you probably have face/iris unlock enabled, I dont have that phone specifically, but some phones will use the screen to make sure there is enough light for the sensor to work

EDIT: I thin it might just be face unlock

[–] [email protected] 9 points 1 year ago (1 children)

I did have face unlock enabled. I doubted it was the cause of the issue, but went ahead and disabled it, can confirm that it's still flashing me.

[–] [email protected] 3 points 1 year ago (1 children)

I can't say what it could be then. I would be inclined to think it a software bug considering it seems to only happen under this specific scenario?

[–] [email protected] 2 points 1 year ago (1 children)

In further testing, any use of the fingerprint sensor can cause it. Lock screen, or in app authentication. It's like the flash that's normally under just the scanner instead happens on the entire screen. It happens consistently if I tap the scanner for about the shortest possible time I physically can.

[–] [email protected] 3 points 1 year ago

ah, that might indeed be indicative of a hardware faliure

[–] [email protected] 3 points 1 year ago

I just edited OP with a video.

[–] [email protected] 15 points 1 year ago

I have a Pixel 7 and mine does the same flash bang thing on fingerprint. I just figured it was to "see" the fingerprint better. I only notice it when it's really dark.

Hilarious way to describe it. I knew right away what you were talking about.

[–] [email protected] 10 points 1 year ago (1 children)

Better than being fingerbanged by your flashprint sensor

[–] [email protected] 7 points 1 year ago (1 children)

At least that could be fun. This only hurts.

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago)

Lol, I guess.. 😃

[–] [email protected] 9 points 1 year ago (2 children)

5head?

[–] [email protected] 9 points 1 year ago (1 children)

[–] [email protected] 6 points 1 year ago

More accurate than the my description, turns out, but same energy.

[–] [email protected] 7 points 1 year ago

It's a meme lol. Like "you didn't think of the obvious solution? -hand on forehead-" but meme-ified

[–] [email protected] 6 points 1 year ago* (last edited 1 year ago) (3 children)

This could be a possible issue with your screen but it's most likely an issue with the Finger Print Sensor (FPS) Software. With Pixel 6 and up the FPS software works in conjunction with the LCD (Since it's on the screen). You should take it to an authorized Google repair center (for example a uBreakifix) and the issue will likely still be covered under the manufacturer's warranty(free of charge). There's a specific program that Google gives these repair centers to reinstall the FPS software on it each time they do an LCD swap. I'm sure that they would be willing to reinstall the software on your Pixel without going through the process of switching the LCD to see if it fixes your issue. Shouldn't take more than 20 mins but it could be longer if they're backed up on same-day repairs. Source: I had to do this a many times for the Pixel 6. And I vaguely remember a customer with a similar issue on the 6 pro.

P.S. Before doing this you could try a factory reset on your phone to see if it fixes the issue. Or start Android in safe mode to rule out any 3rd party software that could be causing the issue. (Though I doubt it, I have a feeling the issue will persist).

[–] [email protected] 8 points 1 year ago (1 children)

No need to go to a repair shop, Google offers this publicly https://pixelrepair.withgoogle.com/

It does factory reset the phone so make sure your data is backed up

[–] [email protected] 2 points 1 year ago

Cool, I'll give this a shot when I have some time. Hopefully it's just a software issue, I'll be a bit annoyed if i have to have ANOTHER screen replaced on a 4 month old phone lmao. Thanks for the info!

[–] [email protected] 2 points 1 year ago

I just edited OP with a video.

[–] [email protected] 1 points 1 year ago

This seems like the most likely solution, unfortunately. I say unfortunately because I've had this phone for all of 4 months and it's been nothing but screen and fingerprint issues lol. I'll try the fps reinstall program the other person posted first, and then if still nada, guess I'm going to UBIF again.

[–] [email protected] 5 points 1 year ago (2 children)

I am not an expert, but that kinda sounds similar to my old phone when the screen connector broke. It went greenish white and really bright. I dropped mine though.

[–] [email protected] 2 points 1 year ago (1 children)

My fucking mobile does this now when it gets hot! If I play a game or put it on charge the screen will ping up but green-tinted and sometimes with part of it missing. As long as the temp is low it works A-OK.

Though, I threw my phone from the third floor of a hospital after a suicide attempt to stop the brain scanning tech inside from frying my brain and allowing UK armed-response police from tracking me.

The nurses rescued it from a puddle in a tarpauline covering the ground within 30mins.

3 days later I realised the brain scanning was a delusion and I was just "insane in the membrain" after the OD.

[–] [email protected] 3 points 1 year ago

I hope you get the help you need. Im glad that the phone was recovered. I threw mine down some hospital stairs too going to grab something from another floor. I also bent one in a car door. It had a 30° bend but worked fine.

[–] [email protected] 1 points 1 year ago

Was it just for a split second, almost like if you use the front camera with flash? If so, yeah that's exactly what mine is doing, but when I unlock it. Bizarre.

On Lemmy, You can embed a video like this:

Thank you! My lemmy-fu isn't that strong lol.

[–] [email protected] 3 points 1 year ago (1 children)

Had exact same issue on my Vivo X70 Pro+. And the cause was something I doubt will be there on a Pixel. My device has an option to always show fingerprint icon, or show only when screen is lit up.

Always showing the icon flashbanged me with light as well. You might try this if that option exists for you.

If it doesn't, then turn off AOD.

[–] [email protected] 2 points 1 year ago (1 children)

I don't believe the fingerprint option exists on the pixel, or equally likely, I'm blind, especially now. I'll check AOD though!

[–] [email protected] 1 points 1 year ago

It should be there in the security menu.

[–] [email protected] -5 points 1 year ago (2 children)

Switch to a pattern or pin to unlock you phone. These are the ideal methods for security. Hopefully, someone will have a better solution. I'm on LineageOS, so, I don't know if it is an issue with Android.

[–] [email protected] 2 points 1 year ago (1 children)

Yeah physical security isn't my biggest concern with the device. It's more of an accidental touch prevention mechanism for me, so the easier it is to get it out of the way when I want it gone, the better, at least for my use case. This is... Not working, though, my retinas hurt now.

[–] [email protected] 3 points 1 year ago (1 children)

You might be able to get help over on the xdaforums.com if you can't find it here.

[–] [email protected] 2 points 1 year ago (1 children)

I'll check there tomorrow, if I don't see any answers tonight. End of the day, I'll just turn off fingerprint and use something else, more than anything I'm curious what's causing it.

[–] [email protected] 3 points 1 year ago

As a Pixel 7 pro owner, I would like to know if this is a software or hardware issue too.
