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

[–] Ookami38@sh.itjust.works 15 points 10 months ago (1 children)

Aw heck, I hadn't thought of that.

[–] BluJay320@lemmy.blahaj.zone 11 points 10 months ago (1 children)

Happy to help, my friend

[–] Ookami38@sh.itjust.works 4 points 10 months ago

It worked! I'm not blind this morning!

[–] drwankingstein@lemmy.dbzer0.com 17 points 10 months ago* (last edited 10 months ago) (3 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

[–] Markaos@lemmy.one 8 points 10 months ago (1 children)

No, face unlock on Pixels doesn't do anything to illuminate your face, it simply refuses to work if the lighting's too dim. It's actually worse than the face unlock in Google Smart Lock in dealing with low light environments.

[–] laenurd@lemmy.lemist.de 6 points 10 months ago (1 children)

*most pixels

The 4XL had the best face detection in the industry, employing an additional infrared camera with its own invisible light.

[–] ilickfrogs@lemmy.world 3 points 10 months ago

I didn't buy a pixel 4 because it was Google's first attempt at face unlock. Decided to spice things up and get an iPhone for a change. FaceID is fanfuckingtadtic and I'm sad that my pixel 7 doesn't have proper face unlock.

Imo: rear mounted fingerprint sensor > proper face unlock > under screen fingerprint.

[–] Ookami38@sh.itjust.works 8 points 10 months 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.

[–] drwankingstein@lemmy.dbzer0.com 2 points 10 months 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?

[–] Ookami38@sh.itjust.works 1 points 10 months 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.

[–] drwankingstein@lemmy.dbzer0.com 1 points 10 months ago

ah, that might indeed be indicative of a hardware faliure

[–] Ookami38@sh.itjust.works 1 points 10 months ago

I just edited OP with a video.

[–] BigBlackCockroach@lemmy.world 10 points 10 months ago (1 children)

Better than being fingerbanged by your flashprint sensor

[–] Ookami38@sh.itjust.works 7 points 10 months ago (1 children)

At least that could be fun. This only hurts.

[–] BigBlackCockroach@lemmy.world 3 points 10 months ago* (last edited 10 months ago)

Lol, I guess.. 😃

[–] someguy3@lemmy.ca 9 points 10 months ago (2 children)

5head?

[–] tfw_no_toiletpaper@feddit.de 10 points 10 months ago (1 children)

[–] Ookami38@sh.itjust.works 6 points 10 months ago

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

[–] Ookami38@sh.itjust.works 7 points 10 months ago

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

[–] peter@feddit.uk 6 points 10 months ago (1 children)

I've got a Pixel 7 Pro and this doesn't happen with mine so it's possibly a defect with yours. No idea how that could happen, though as it sounds more like a software issue

[–] Ookami38@sh.itjust.works 3 points 10 months ago (1 children)

It's a really weird issue for sure. I've had nothing but issues with this screen. I've had it for all of 4 months, and had to have the screen replaced for a band across the center horizontally that was not accepting touch. Three screens later, and finally I have one that doesn't have any visual or touch defects, and now I get flashbanged if I fumble unlocking it. Ugh.

[–] Jean_Lurk_Picard@lemmy.world 2 points 10 months ago* (last edited 10 months ago) (3 children)

If you're consistently having screen issues with your Pixel and it's not due to any accidental damage but straight out the box it could very well be a problem with the motherboard. Various ways to solve this like contacting Google and seeing if they'll do an in-warranty replacement device, or you could see if a Google authorized repair center will do a MOBO replacement. However the suggestion I commented elsewhere in this thread is the better 1st step to take

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).

[–] AnEilifintChorcra@sopuli.xyz 6 points 10 months 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

[–] Ookami38@sh.itjust.works 1 points 10 months 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!

[–] Ookami38@sh.itjust.works 1 points 10 months 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.

[–] TheLordHumungus@lemmy.world 5 points 10 months 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.

[–] cashews_best_nut@lemmy.world 2 points 10 months ago

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.

[–] Ookami38@sh.itjust.works 1 points 10 months 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:

It's not a green glow. The WHOLE SCREEN flashes green. I've noticed the glow where the fingerprint scanner is. This isn't the issue. It's also consistent and persistent through reboots.

Dude holy shit if my phone was flashbanging me every time someone texted... Well honestly, I'd be fine, but it'd be in the river just on principle

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.

[–] Ookami38@sh.itjust.works 2 points 10 months 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!

[–] EvilBlackCat@lemmy.world 1 points 10 months ago

It should be there in the security menu.
