Fingerprint Sensor always shows up when taking device in hand, hasnt been like that? - Xiaomi Mi 9 SE Questions & Answers

Hi,
no idea if i just got nervous and did not figure out earlier or it bugs indeed.)
Thing is i put a tempered glass on the screen and all went fine for two days.
As the glas wasnt exactly medium placed i wanted to correct the position, got a dusk between tempered glass and screen, no more wipes at home.
So i used a wipe for glasses to wipe the dusk corn from temeperd glass.
After wiping with that now as soon as i just pick up the device display shows the fingerprint symbol "greyed out/dark mode", note as bright as when using it, tapping on, but in a decent grey/anthrazit.
Wake up on lift was disabled from the beginning, double tap to wake is on as it was, turning off makes no differnce.
So did it "wake up" that way since first day and i just didnt notice it nervous like now or did i mess it up with the wrong wipe on the tempered surface?(
Edit:
think i messed it up, as soon as i hit the power button to lock the device finger rint symbol gets brighter waiting for input.
You gus know a way to cleen the display isded side of tempered glass without interfering then maybe?

Clairivue XT (HD) Glass Screen Protector

Bought this for my wife's phone. Pretty unhappy with it. First off there was some glue in the middle of the glass when i was about to apply it to the phone. So i already had to wipe this off otherwise there would have been a glaring mark on the screen. I used some glass cleaner and had to scrub pretty hard with a microfiber cloth to get it off. Once I dealt with that the screen itself fit pretty well.
But we shortly after we noticed that there was a major problem with the proximity sensor. You could see a faint red glow always on and the phone would not detect how far our heads were from the screen. Using a third party app the sensor would always read 0.0 cm. Once I removed it, everything was operating fine again. Lastly, we also noticed that the touch sensitivity was decreased while using the screen which was extremely annoying. Some screen swipes or taps just didn't register with the phone.
Overall, I would not recommend this product.
Currently, I'm still trying to email them about replacing it with a normal skin.

[Q] Touch screen doesn't respond to touch

My S3 has been working fine for months sort of. I bought it off of ebay with a huge crack in the glass, then my brother dropped it and all the glass fell out. To use the phone we has to touch the bare LCD of the phone, which after a while we just but a screen cover over it. I waited 2 months, bought a new glass replacement and put it on, everything worked just fine. After a little the home button when pressed to the left a little would make the screen go crazy. it would start tapping and swiping in random places. After locking and waking the screen the phone was normal again. after that, i removed the glass again, and this time when putting it back on if i pushed the home button it pushed the glass down a little, which would turn my screen black. locking the phone and waking the screen again turned the screen back on. Also the screen was a lot less sensitive, i'd have to tap a key 2-5 times sometimes to hit a specific letter. whenever that happened i put 3 dsi's to weigh it down and push the screen down, which would improve the sensitivity. that worked twice, and now my screen doesn't respond to touch at all. the screen will wake, but only when i press on the bottom right corner of the screen will it respond to touch. Any word on what could be the problem? i need to know what to buy to replace in the phone. I've already taken the whole phone apart and plugged everything back in, after i had tried everything to get my phone to respond. Could this be a digitizer problem, or an LCD problem? any possible fixes without having to replace anything?
The first issue was using the device without the glass installed. By touching the bare LCD you most likely damaged it. Your best bet at this point is probably going to be to replace the Touch assembly ( Glass / LCD Touch digitizer ) . Also keep in mind, when doing any sort of Screen replacement. Be sure to keep everything as clean, and dust free as possible.

screen turns off after I turn it on

I'm having a problem where in low-light areas, my screen turns off a second after I turn it on. The only way I can get it to stay on is by plugging the phone in or unplugging it if it's already plugged in. It seems like there's an issue with the light sensor / proximity sensor that helps keep the device off when it's in your pocket. I'd like to fix, disable, or remove this feature. Anyone else having this issue or know how to fix it? I've encountered it before with the lightflow app where the solution was to remove lightflow, but this is built in which makes it more difficult. Fyi My phone is rooted.
No suggestions for a fix, sorry. I saw behavior like this (screen turning off) when I put mine in an arm band case with clear plastic covering the whole front of the phone. I assume the proximity sensor thought the phone was in a pocket, etc.
The only thing I can think of to simply learn more about the problem is to install CPU-Z and look in the Sensors section to see what the LGE Proximity sensor is reading.
A screen protector that covers the sensors can also cause this.
I get this in low light, too. I have to point it at a light source to get it to turn on. Very aggravating. The longer I use my G4, the more flaws I find.
Do you guys have a tempered glass screen protector on? I have this too, and confirmed this is what it's from. When I had one that didn't directly cover the sensor I had zero issue. It may also be that the sensor isn't that great or polls on too slow of an interval.

Interesting. Does this happen in no-light situations as well? Or is there is a "dead zone" between normal light, and pitch dark?
I tried mine in an almost-fully-dark scenario, in a closet with the door almost fully closed. It turned on normally using both the power button, and double-tapping the screen. Mine is a Verizon model, 610B software.
Thanks @RedOCtobyr for pointing out it could be the screen protector

Yes! I have the tempered glass screen protector. I'm going to remove it now. Besides this whole light sensor issue, I absolutely hate this thing. Compared to a plastic screen protector, I can barely move/drag my finger across the screen because it grips my finger so much. I also feel like it messes up the touch sensitivity so that a lot of lighter touches don't register. Whether that's true or not, the excessive grip this thing has on my fingers and this whole sensor issue is reason enough to tear this piece of crap off.
...
Yep. Light sensor now works in low-light situations but detects when it's being blocked in close proximity. It feels a lot better to touch the screen now as well. Anybody know of a good plastic screen protector to order off Amazon?

I love my tempered glass. Just not ones that cover that silly sensor. I can't say for sure but I feel my G3 glass also covered it without this issue, or at least from what I remember.

how did you over come that issue with the armband. i am having the same problem right now thanks.
Follow steps below to re-calibrate proximity sensor(must with the glass protector is installed and which is sensor covered up)
1. TYPE "277634#*#" in phone dialer. Hidden Menu screen will show up.*
2. Select "Device Test"->"MT", it will show "system will be restarted", then choose OK.*
3. After reboot, GENESIS MiniOS 3.1 screen will show up, press "individual item+power" while power button is pressed.*
4. Next, find "sensor test", enter it(do not block the proximity sensor), the proximity sensor will be automatically calibrated. Then block proximity sensor two times to exit.*
5. Find "Back to the MainList", enter.*
6. Press "Normal boot+power" while power butten is pressed to reboot system, done.
Now the problem should be solved.

Thank you for this. Although on Marshmallow the Hidden menu code has changed. I found this on reddit which helped.
User: Tramagust (I can't link because I have not made enough posts yet )
"It is *#546368#*MODELNUMBER#
So for the international version it is *#546368#*815#
For the Dual sim version it is *#546368#*818#
I assume for the NA version it is *#546368#*811#"
I will see if it makes a difference. Cheers

Fingerprint sensor Tips

Forget all the "you need to not press hard" bull****, it's way simpler than that.
Register your finger while holding the phone in one hand, position your fingerprint on the sensor exactly as you would casually, keep registering it that way, from a limited position on a one handed held.
If you do a "proper" registering process of your fingers from artificial positions just because you think it helps the sensor, it won't work, even minimal changes in your finger shape will make it generate different keys that will not match a real life press.
I registered my fingers from positions I would practically use to unlock later on, the success rate is now 100% as long as I don't miss the sensor on dark screen, no matter the pressure or the time you hold your finger on the sensor, it will now work every single time

I tend to agree with you. I registered both right and left thumbs and they both work on command. No 2nd or 3rd attempts yet. Just register the thumbs like you would naturally hold them on the screen(flat).
I also feel like the fingerprint scanner icon is a bit misleading, given the fact that the sensorbis actually above the actual icon

But when I try to casually tap the screen to register fingerprint naturally, it won't register, keeps saying press harder or hold longer
Or register the same finger twice.. That's the better solution

The tap needs a certain amount of pressure, not too light either

Same, and i registered the finger I'm going to be using most twice. Registered casually and from a natural position. I think mine has failed to unlock maybe 3 times in a week. In this case...keep it simple don't over think it.
Sensor is off
I noticed when the screen is off in dark mode and u take a flashlight on a angle of the screen i noticed the sensor is like a U shape just slighty to the left of the finger print icon, now that i kinda setup my finger print just a tat left og the finger print icon its been 100 procent i also noticed moist fingers work better . i could be wrong about it being a sensor but the U shape i think would be the sensor

You don't need to move your finger away, the sensing part of the sensor is perfectly aligned in the middle
New update on firmware.Science for snapdragon. SBA TO SD3. Made a world of difference for me. Can't wait for my replacement Whitestone to get here to see if sensor works any better with tempered glass. This update absolutely made a huge difference. Not slightly, very significant change for me. I register both thumbs twice and I couldn't get it to not unlock every time. 50+ unlocks and maybe 2 failures. I stopped counting at 50.
Will it work on verizon or only unlocked?

I'm waiting on my Whitestone replacement as well. Can you keep us informed on how the sensor works with your new install? I had to pull the last one. It was horrible. I miss my glass...
The problem for me and many people is that when the finger being scanned is dry, scanning won't work (and will be asked to "press harder"). Some people then try to press really hard and it will, forever, say "not match".
People with moisted fingers will not have this problem and will not understand the kind of people I mentioned above. Since I have S10+ for a month, I, kind of, know when the scanning will not work. I will use face scanning instead or if I really want to scan my finger with whatever reason, I just rub my nose with my thumb then it will 100% work (greasy nose does the trick).
I don't know if Samsung can ever fix this since it is not how accurate the reader is.
Dry fingers don't work with the fps even when removing the pre-installed screen protector?
I am debating to remove the screen protector and my main points are:
1. The protection offered by the pre installed screen protector is minimal either way.
2. That the screen colors and usage will become much better.
3. That the fps will work much better even with dry fingers due to the oleophovic coat of the screen.
Has anyone who removed the screen protector tested this?

I removed mine yesterday and it does help a little with the fps. I still don't like the fps though, I would much rather have a Face ID equivalent. Or have the fps on the back.

I had reached out to Whitestone because my first install failed. I had the WSD on my s9+ and went through 5 or 6 in the year (I dropped my phone a lot). So I knew what I was doing, but the first try had a huge bubble. Tried doing the cleaning and reinstall with the backup glue and had a bunch of microscopic bubbles in the top and bottom (guessing I didn't clean it well enough before reinstall). I wasn't sure how to register warrenty wise because technically it worked fine, just was having FPS issues. They ended up replacing without me paying for the shipping which was awesome of them.
Recieved my replacement today, and the install is flawless. One thing to note is on the 10+ the absorb pads hook into the top tray not the bottom (that was a hell of a mess the first time). The original kit didn't come with the pads pre-installed like the replacement kit.
I haven't even gotten the latest OTA yet, and with the WSD glass, it's just as quick and success rate is the same as when I had the pre-installed protector. Might even be faster than my s9+ was...

Screen protector

Hi all,
I've tried a few makes of glass screen protectors, but they don't go down on the screen properly. I get an oily looking patch in the middle. But it doesn't disappear if I push it down, it's odd.
On previous phones, when I've dropped the glass on, it sucks down, the ones I'm buying don't seem to do this, they are very non stick. Not buying anymore for now, until I know it'll be good.
Maybe my screen isn't flat, but it's odd the oily patch won't disappear if I push it down?
What makes are you lot using?
Could take a photo later to show you what I mean.
