Mİ 8 Proximity Censor Problem ? - Xiaomi Mi 8 Questions & Answers

Greetings,
after I installed the full-size Nillkin full size screen protector
I bought for the new Mi8 (with Chinese rom), the proximity sensor failed and the screen started to look black.
Unfortunately, it did not work to calibrate the sensor in the morning
is there another way of resetting the screen guard detection of the sensor to the yard? ?

Screen protector problem, replace it with another or run without.

Problem with proximity sensor stuck at max value

Hi all,
I noticed that my proximity sensor isn't functioning. In fact when I call the screen remains active even if I put my hand over the sensor. I used CM10 so I reflashed stock GB ROM and it still does the same. If I use the *#0588# test I always get "Proximity: 1" value. It seems like my proximity sensor isn't working but my light sensor does. What could be the problem here?
I also tried cleaning the screen, lifting the protective plastic but no way, it still doesn't work. Also I dismounted the Galaxy S, tried to blow some air with a compressor, tried to clean the inner surface but no luck...
same thing here

[Q] Proximity sensor issue with tempered glass

I got a new tempered glass screen protector, however, it is covering the proximity sensor located directly to the left of the top speaker. Since it is covering the sensor, I am unable to access the dial screen during calls 9 out of 10 times unless i keep swiping my finger on top of the sensor to get it to work. I got AndroSensor to test out the sensor and it does stay at 0.0in 90% of the time. When it does work, the value returned is 2.0in. I really don't want to replace this screen protector because it is nice and love the smoothness of it but unable to use the keypad during calls is too much.
Is there a way to manually turn on the dial screen during calls? Tried swiping, pinching, you name it.
Is there a hidden setting I could try like entering *#0*# on some phones for a workaround solution?
Is there a way to modify the settings of the proximity sensor? I am rooted.
The weird thing is there is a cutout on the protector but it is on the right side... Most of the pictures I saw of tempered glass for Nexus 6 had the left side covered but right side cut out as well. What's on the right side that is more important than the proximity sensor? Did they not know? Blah sorry for rant...
Its a problem with your tempered glass, contact the company whom you bought it from. Request a defect.
Theres a tempered glass thread in the accessories section where they have the same problem depending on what tempered glass you purchased.
Thanks zephiK, I'll check out that thread!
The below mentioned fix is for brand new Nexus 6.
Did you try going to settings , accessibility , power button ends call, toggle that on and off.
After completing the above mentioned step. Reboot your phone and try making a call. I hope the issue get resolved.
I tried this step on an unrooted phone, which was recieved just yesterday.
I got this fix from some other thread.

Proximity sensor/screen issue during calls?

I am running the latest a stock debloated 6.0 rom from tupac4u right now and having some issue during phone calls. For me I make or receive a call and my display will turn off even before putting the phone to my face. However, getting the screen on during a call is a bit hard to do as pressing the power button doesn't turn the screen on(sometimes have to press it 3 times to get it on). Anyway to fix this, or to disable this? Thank you
Using a screen protector? If yes, it may be blocking the proximity sensor, which is located just to the left of the top speaker grill.
In another thread I'm being told it's a bug with marshmallow. How accurate is that? And yes I am using a screen protector. I'm just not sure where the proximity sensor is so I can adjust accordingly?

I do not use shell or film and have the problem for a long time. Tried everything but nothing helps you get used to it.
Knowing isuses since 5.1 and the sensor is on the top left of the earpiece
Yeah i took a light to find where it was. I have a tempered protector. Tried to use a knife to adjust it, but broke the screen protector. Oh well I'll just skip one cup of tea this week. If I go with a regular screen protector(one of those cheap $1 ones will that still cause issues?
Yup, the oversensitive proximity sensor issue started after 5.1 arrived. I too had a tempered glass covering the proximity sensor and it was working fine when I was on 5.0/5.0.2. I had to remove the tempered glass and get a new one which doesn't cover proximity sensor to fix this problem.
Did the same thing. Got a regular screen protector right now for a cheap, until I can find a tempered model that doesn't cover the proximity sensor.

LG G4 Sprint (LS991) Proximity Sensor Re-Calibration Question.

Has anyone here had success re-calibrating their proximity sensor after installing tempered glass screen protector on? I know that the proximity sensor shouldn't be covered and it's best just to buy one with the cut outs but I read that there's a way to re-calibrate it using the hidden menu. I've tried running the manual and automatic test but all it gives me is Proximity Sensor - Near / Move your hand away, now cover the proximity sensor with your hand test. Not sure if this does anything calibrate it since it doesn't move past that or give me a prompt that the test is done. I saw that Verizon variant had Genesis Mini OS that has to be booted into.
I'm using the Sprint code to get to the hidden menu 5689#*991#. I also tried searching for "sensor" and "proximity" on ShortcutMaster and it shows that the proximity sensor is fine. I know I should just go ahead and get a screen protector with the cutouts but wanted to know if there's a way to adjust the settings.
Thank you for your time.
I had the same issue before and I followed this guide to fix my Sprint variant.

Fingerprint sensor question

Hello people
Also, does any of you have a problem with the fingerprint reader response when using night reading (red filter mode for less eye fatigue).
By day (auto contrast set - stock) and the reader responds without problems.
However, when it gets dark and the phone starts to use night reading, the reader is often unresponsive.
Of the 4 scanned images, it usually takes only one, so I have to put my finger the same way to unlock the phone.
I use protective glass (9H 2,5D curved, tempered by Sigisi).
But I think there will be no problem, because the reader reacts with the glass without problems during the day.
Thanks for the reaction.
I guess that the night mode plus the protective glass is a bad combination
Did you set the fingerprint after applying the glass or before?
With the night reader mode it shouldn't be any problem. The phone automatically, when it detects a finger on the sensor, disables All screen filters. If you notice, when the blue light of the sensor appears, you'll notice that some colors lower it's contrast for a more precise scan. And with the glass, I have a non branded 5D glass and it works perfect. In the only situation that fails reading my finger, it's when I have my fingers wet (by the swimming pool) and wrinkled, but I think that it happens with every Fingerprint scanner. If the scanner works without the glass. The problem is the glass. If not. You want the warranty to remain valid
After aplying
Im thinking about buying this phone, but what worries me if fingerprint scanner works well with protective glass?
I'm using generic tempered glass from the start. Even registering my fingerprints with glass on. No problem so far. Just little advised,I'm using only my right thumb to unlock,and what I did is I repeatedly registered the fingerprint while I'm holding the phone so it will be more accurate.
By the way. I' also set my phone to be on reading mode at night.so far no problem with it. I'm on miui 11.3.3,stable official global rom.
