Hole in Microphone - Huawei P20 Questions & Answers

Hey guys,
I noticed a hole in the holes of the microphone of my p20 (the mic is on the bottom left) . It is the hole next to the usb port. Can you please check, if you got this hole as well? Looks like someone has poked the sim card tool in there and I just want to be sure that its normal. Thanks!

Microphone replacement question.

Hi, my phone mic has stop working no one can hear me.
any one know´s what is the mic replacement for the tornado 2125??
hope any can help me.
thanks.
Strange - already the second with Mic problems for the devices that I watch (all the old ones: Typhoon, Hurricane, Tornado, Excalibur and Vox). It seems that some are offering replacement MICs on ebay, but the more problematic part is to unsolder the old one and re-solder the new on the PBA.
Check first if it is really the MIC and not another problem in the radio part. Try to record a note or a voice tag to see if the MIC is working. Also check if the Headset would work to record.
The mic works ramdom, voice recoder sometimes record the sound other not the radio version is 4.1.13.28_02.61.01 try whit lot of rom´s and the same.
headset is lost but i will try when i found it :S
if you can provide me a newest radio it will very appreciate that.
thanks.
You already have the latest Radio - there is nothing newer for the Tornado. Changing SW will not help if the HW has a problem - and as the recording sometimes works and sometimes not - seems you have a HW problem :-(
Love my phone, but is old know that!
can you help me giving me the correct mic reference?
i will try to fix replacing the bad mic for a new one.
thanks.
See this thread. Search ebay for "microphone dash".
I don't know how you would be able to remove the old mic and resolder the new one. I would not dare doing this. Best option is to open the device (careful! - don't rip off the keyboard cable) - seach for descriptions how to do it - and then clean the PBA from dirt that may have accumulated there.
Edit: all identically looking HTC microphones should work. There is no reason for HTC to have different MIC in the same shape. I found the following item-ids matching on ebay:

Mic just work again xD no more problem whit that.
now the Ring Speaker stop working only work´s sometimes and sound rare :S
what is the replacement for that speaker??'
thanks for all.
What did you do to make the microphone work again?
The ring speaker hardly ever breaks, but it is the same for Typhoon, Hurricane and Tornado. It is more probable that dirt has accumulated on the speakers membrane and/or that the contacts to the PBA are not working properly.
If you had already disassembled the device you can take care of both. Check the contacts on speaker and PBA first, as removing and cleaning the speaker is more delicate to do.To remove the speaker from the middle frame you have
to disassemble the device (several manuals available around the net) to its main parts:
Front cover with LCD and PBA
middle frame (with ring speaker, camera and buzzer)
then remove the 3 black screws from the black plastic cover,
now carefully lever up the camera which is glued to the frame with a small double adhesive ring around the lens from inside (really delicate if you don't want to break it!). You could possibly skip that step, but then the next step will require you to bend the flex cable from the camera very much. Never bent it much on my devices, so I cannot tell if that would not break the camera either.
carefully lever between the black cover and the frame (small adhesive frame around the edge) and step by step pull it up to finally remove it. Take care not to rip too fast as you need the adhesive later to keep it stuck well to not vibrate and distort the sound.
now you can access the speaker which should lift up together with the black plastic cover. The speaker is glued with double adhesive tape to that frame - again care to to lift it up.
good luck!
I conected the hands free, to the cellphone and it´s worked again.
i disassemly the phone clean whit isopropyl alcohol and nothing.
only the ringer speaker works somethimes so i thinks is faulty and sound like weird
try to change for another ringer.
thanks for you help!
Ah, that is interesting The 3.rd ring on the plug (the one you do not have on normal plugs) is for the external microphone and shortcut to grounds acts as pickup/hangup button. So it seems that some dirt in the socket has created confusion regarding the microphone?!
To my experience the switch that toggles headset/normal also steers the use of the external/internal microphone. Consequently you should have noticed also the sound disappear (when going to "headset" mode).
When you disassembled the device already, look at the rear part of the headset socket. You see at the left side a gold contact that is normally closed and that opens when you insert a plug. The closed contact must be well connecting or otherwise you are stuck in headset mode. When open (plug inserted) use a wooden toothpick + alcohol to clean the surfaces. Depending on the place where you keep your phone when carrying, the socket eats grid and dust that accumulates at the rear part - so keep the socket clean.

[Q] Earphone jack issue and scratch case

Hi,
I just got a TF and my earphone jack seems to have poor solder joint. I tried 3 sets of phones and all give the same result. Sometime I only have sound on the left side, I need to wiggle the connector a bit to get sound for both side. Sometime if I accidentally touches the jack, I am back to 1 single side sound. Doesn't anyone have this issue? I saw someone posting the same feedback from another forum so I just want to confirm that. Also, onto of the ASUS word at the side of the tablet there is a small scratch and many seems to have the same scratch there. I am less concern about this scratch.

[Q] Holes on left and right side of tablet?

I've had my tf700t for a few days now and have been assuming the mic was one of the tiny holes on the left or right sides of the tablet, when in fact the hole on the back is the actual mic.
So my question is: What are the holes on the left and right sides of the tablet?
Just found an online user manual and found that the hole on the left is a reset button and the hole on the right is a mic and also the hole on the back is a mic as well.

Accidentally poked top right microphone hole

I was trying to push out the sim/sd card tray and I accidentally poked the top right microphone hole with my tray tool. Does anyone know if i may have damaged the microphone or "BROKE" any water seal? If you have broken the water seal, may you please take a picture with your tray tool stuck all the way, so i can see how far it is in there until the mesh breaks

What is the small hole between the USB-C & Speaker?

Like the title, there is a mic to the left of the USB-C port, but there is also a hole on the other side between the speaker & the USB-C. What is it? I got a case and this hole is blocked, should it be open?
I'm pretty sure it's a microphone. I have a Spigen case, the hole is open just for your reference
htc u11 have 4 microphone for 3D Sound Recording when record video....your case is not official try to change
The four microphones are different than this hole. The there is one microphone on the bottom, one on top front next to the front camera, one on the very top edge and one on the back bottom. The hole I am referring to is the other one on the bottom edge. I attached a photo.
The edge of the loudspeaker board sits pretty close to the port, looking at the teardown on iFixit. Tweeter for the speaker perhaps?
The four mics are shown in this pic from HTC. The little hole must be something else.
