Doubt physical problem - Xiaomi Mi A2 / 6X Questions & Answers

The problem I have is that when I touch the phone or touch my fingers on the part between the camera and the fingerprint sensor, there is a sound as if something is loose inside the device, this sound increases if you touch it several times. upper part that is above the camera. Also, however, when placing it on flat surfaces such as desks, placing it as commonly placed any device also produces this sound (As if it had something loose inside). GOOGLE TRANSALATE
My doubt is that if it is something NORMAL the problem that I have is that the mobile on touches having had or to do it with the fingers in the part between the chamber and the sensor of fingerprint, produces a sound to itself as if something was sluggish inside the device, this sound increases if touches several times the part top that this one arrives of the chamber. Also on having placed it on flat surfaces as offices, placing it since any device is placed produces also this sound (As if it had something sluggish inside). THEWORLD TRANSLATE

Is it something new or did uou have this sound since the beginning ?

Solved, it was factory error they replaced it with a new sealed one.

Rattle from the slider wheels? Fix it.

I had not had the tiny rattling sound that comes from the rolling wheels under the slider until today, after I dropped my X1 for the first time. But, after reading around and finding the source of the rattle - the tiny metal wheels under the front of the device - I was able to stop the noise. (not to mention being relieved it wasn't something more serious)
The noise is the light rattle coming mostly from the top end of the front as well as the bottom, louder at the top. It sounds almost like a loose screw and makes noise even just from turning the phone upside down, more high-pitched than the other possible noises. Testable by putting pressure on the front of the device, just to the left of the light sensor. if you push down and shake the noise disappears. The source is the little roller wheels under the slider.
This noise is not the optical joystick and not the camera rattle. The joystick rattle can be detected by holding your thumb with a slight bit of pressure over the optical joystick and gently shaking, if that noise goes away, this will not fix it. If the sound is more of a quiet clunking sound that only happens with a jolting shake, the source is the autofocus of the camera and will not be fixed by this.
How I stopped the noise:
I fixed this by cutting thin slices of clear tape, about 1 mm wide and 3 mm long and placed them flat on the metal of the keyboard, then closed the phone. I slid some paper in the gap to make a cushion and applied pressure to the front face to push the tape up onto the wheels more firmly. No more noise.
To make the fix invisible, use a second strip of tape to hold the edge of the tape that will remain so you can position it far enough inside it cannot be seen and then remove the second strip.
Credit to qpwoeipt's post that got me to this idea: http://forum.xda-developers.com/showpost.php?p=3171129&postcount=11. There are photos in that post that will illustrate the location of the wheels, plus you can see them if you look in the gap above the keyboard.
Cool tutorial there dude!!!
Seem a bit excessive though for something i never notice or get bothered by
Still cool idea!

The noise I was suddenly hearing was quite loud and happened with the slightest movement, very much like a small loose screw moving around. Since it happened only after dropping the phone (for the first and hopefully last time), I really wanted it eliminated.

Slight rattle when tapping screen, anyone else?

I got my crystal pro on Sunday, overall really happy with it (will be even happier when I get .124 and the improved AOD!) but am noticing a very slight rattle when tapping on certain parts of the screen.
It only happens when I tap the top right part of the screen, it is very minor but is certainly not consistent with the rest of the display. It is the part of the screen that will be sitting adjacent to the rear cameras so maybe it is the camera mechanism? Probably normal but I am kind of OCD about this kind of stuff.
Anybody else noticing this on their pro?
Same here next to the cameras. I thought it's the OIS but my first p30 pro (display issues) didn't do that or i never noticed it!

I can confirm that it is there, and if you tap and listen closely, the sound is originating from the back, so it's most likely the OIS in the cameras.
But it isn't an issue for me, as you have to use some force while tapping it to hear that rattle, using the phone normally with slight taps like I use every other touchscreen device, I can't hear any rattling sound whatsoever.

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 Shaking / rattling sound of camera module

My Redmi Note 10 Pro makes some sort of rattling or shaking sound as if something were loose inside the camera module when I put it down (on a hard surface such as table, doesn't even have to be forceful).
I can also tap on the inner side of the camera module to produce that sound.
Is that the camera stabilizer? Does anyone else have this rattling?
It really doesn't sound healthy, but everything wokres fine...

I do feel the same. Weird, but, oh well.
I only hear it when I put the phone done with a bit more force, putting it down normally or tapping (even strongly) doesn't produce that sound.
Same here. I tend to think (hope?) it's the stabilizer as well...
Yep, mine arrived today. I also noticed the rattling when I tap on the camera module and when I put the phone down on a hard surface..
My rattle is pretty significant even with only gently placing my phone onto a surface. Did anybody get their issue sorted?

I don't think it's an issue, just how it was designed. It was the same with my last Xiaomi phone and it's still like new after 3 years.

How To Guide Virtual proximity sensor - potential fix

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.
