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.

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.

[Q] Fix curved speaker grill

Hi,
You all have seen topics about screens not correctly aligned with speaker grills. My issue is a bit different. The top speaker grill seems to be curved (the middle of the grill is lower (like 0.5-1mm) than the left and right border).
In fact, in the corners, the screen is flush with the grill but not in the middle, the screen is a (very) little bit higher than the speaker grill but I feel it when I swipe down notification and it bother me. I realy don't want to return this phone because everything else is perfect so here is my question :
Do you have any clue on how to give a "flat" style to the grill without damaging the screen/speaker/front camera... ?
Thank you in advance.

which circuitry is embedded in the frame?

Hi,
Rebuilding my z3+ I notice that there are pads from several of the ribbon circuits that connect to contacts in the inner edge of the frame. I don't have pictures, but it looks as if these connect to the aluminium strips that form the outer sides of the frame. So my question is if anyone know their function. I notice that the non-original frames are missing some of the contacts.
Do the frame sides form part of the system of antennas? If so, which? GSM/Wifi/GPS?
Could there be some other function?
B.R.

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.

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.
