Being flashbanged by my fingerprint sensor
Being flashbanged by my fingerprint sensor
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?
Edit: autocorrect
Edit 2:
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
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.
I just edited OP with a video.
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.
Better than being fingerbanged by your flashprint sensor
At least that could be fun. This only hurts.
Lol, I guess.. 😃
5head?
More accurate than the my description, turns out, but same energy.
It's a meme lol. Like "you didn't think of the obvious solution? -hand on forehead-" but meme-ified
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
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.
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).
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
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!
I just edited OP with a video.
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.
On Lemmy, You can embed a video like this:
Which looks like:
Thank you! My lemmy-fu isn't that strong lol.
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.
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.
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.
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.
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.
I don't believe the fingerprint option exists on the pixel, or equally likely, I'm blind, especially now. I'll check AOD though!
It should be there in the security menu.
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.
fingerprint is more secure than pattern and arguably pin
Its arguably more secure in public places since most people can decipher the average pattern and sometimes pin. video surveillance is everywhere now days.
From a legal perspective, a pin or pattern have more protection.
The best solution would be to have bio metrics as a username and use a password.
My assumption is that they're referring to the case of officers being able to compel you to unlock a fingerprint or face lock, but not a pin or pattern. Either way, it's not relevant for my use of the device.
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.
