How To Guide Virtual proximity sensor - potential fix - Redmi Note 10 Pro

Dear all,
I had problems with my Note 10 virtual proximity sensor over the last months and it went worse from day to day.
Reading details in how the sensor works, I tried to figure out what might cause it not working properly.
The sensor seems to use the top ear phone speaker to broadcast ultrasonic sound and detecting whether it reflects.
So this lead me to the assumption, that a dirty speaker might cause trouble.
Now that speaker is so small that cleaning it is difficult.
This is what I tried:
I took a very small needle and rubbed it from left to right and back and forth on that speaker. I tried to get off as much dirt and dust as possible from it very small holes.
Difficult approach, but you might try that a well. A needle, some cleaning liquid, something to blue away that dust.
After I tried I first noticeably that the ear phone speaker was much louder again and testing with a WhatsApp voice message and with the CIA test menu, the sensor reacted much much better.
I'll give it some more days of testing but wanted to share those thoughts with you!
Let me know if you also have success
Best regards,
Christian

is there any fixed or module?

Promoting my app that blocks screen during phone calls.
It will help to minimize effects from non-reliable ultrasonic proximity sensor.
So even if screen suddenly turns on you'll not press something by ear or cheek.

[Q] Dodging Dialer

Ok... I've tried my best to comb through the forum, but no one seems to have this issue.
Whenever someone calls me, and after I pick the call up, the dialer would disappear into a black screen upon my touching the screen. And when I lift it, it would appear again, but disappear when I press my finger. This has happened several times over the last 2 months. Sometimes it will happen when I make a call as well.
I have noticed that it happens with or without a screen protector.
Is there a solution to this? Thanks.
The proximity sensor is at The Top right of the screen next to the front camera. It turns the screen off when it detects the phone is at The side of your face, so you don't press buttons during your call.
If your holding your phone upright and your finger covers the proximity sensor during a call it will do the same thing. Just make sure you keep your fingers away from the sensor during a call.
I'm pretty sure the sensor is disabled if the phone is laying horizontal, but not 100% on this.
The sensor also does other cool things, for example, if you use your phone as an alarm, no need to deal with the snooze button, just put the phone face down and it will snooze.

I thought that was the case, but I have been using it (on speaker) away from my face and hands.
Perhaps I should pay more attention to this function before my next post.

[Q] Proximity Sensor Problem

has anyone had issues with the Proximity Sensor not sensing your face properly and the screen turning on during calls? I have had several calls where the mute, speakerphone, or end call button were pressed while I was in the middle of a conversation. I am holding the phone to my face, touching my skin. No space between the sensor area and my ear at all.
It's very annoying.

Yes. The worst is when you turn the speaker phone on in the middle of a call and get your ear drums blasted.

Yes, that is exactly what has happened to me a few times now.
Sucks big time, I had some app that made the flash turn on when a call was coming in, removed that, it seems like things are better, might have been the culprit.
If you're rooted, you can use Rezound Prox Sensor Calibrator from the Play Store to adjust the minimum and maximum values to get better results from your proximity sensor. I had to do that especially while running an AOSP ROM on my HTC One.

Question Excessive hardware sound when flipping the phone

It's been two days since I started using this phone.
Today, I can hear an excessive sound coming either from the camera lens or the front speaker. {Noise heard better from front side of the phone}
This happens when you try to shake or flip the phone even gently. I know usually the camera lens on every phone makes a little noise.
But this is extreme. It's almost like there's a tiny piece of hardware broken inside and it's moving even if you shake the phone gently. I either did not observe this issue or it wasn't there for the first two days.
Can anyone confirm if it's the same?

Yes, even in mine there is a kind of muffled noise
Hi guys.
It's from the cameras. If you try this with the camera app open you will see that the noise stops.
Optical Image Stabilisation most likely. Camera lens can move to handle shake.
I don't hear anything noticeable from mine. Just a VERY slight muffled noise if I shake it while holding the lenses right up to my ear, but nothing I would notice if I wasn't specifically trying to find a noise.

Question Proximity sensor problem

My phone is acting wired from two weeks ago. The Display is getting automatically off without even I'm going near to Ear. To WhatsApp Audio messages also when start to listen the auto the screen is getting off. I tried maximum possible to clean the phones upper part but still same. Please anyone help me how to fix this issue.
Sorry for my Bad English.
Thank You..
same with me. i couldn't solve the problem
I'm sharing this exact same issue when listening to WhatsApp Audio Messages.
I think it appears to happend more often under dim light conditions, but also when the sun is shining and I'm outside.
To me it seemed always help to hold the phone straight, rather than rotated a little bit.

Please Fix

Proximity sensor ticking noise

hey,
I noticed earlier during a call that the proximity sensor makes a ticking noise when the display is switched off. The proximity sensor is located at the top right of the frame. Nothing can be heard when the display is on. The noise is always audible as long as the screen is off.
Has anyone else noticed that too?

Oh my god, I've been searching if anyone has this issue too (I also have an X5 pro) and find this thread via google search.
I'm not sure what's causing it but noticed it last week, first I thought it was the vibration motor for some reason. But yeah I definitely hear it when the screen is off only. It's most annoying during a phone call
This might be a defect since my Find X5 Pro is not producing any sound from the proximity sensor region. I've been testing in a really quiet environment.
