earpiece replacement - Xiaomi Poco F2 Pro (Redmi K30 Pro) Questions & Ans

I dropped mine in water for 5 seconds. It seemed alright at first but now the earpiece cracks a bit. I want to replace it but I can't find the part online. Does anyone have any links to the earpiece?

Earpiece Volume Went Abysmal

Hi guys,
My screen got a bit dirty today so I decided to get wet a piece of cloth and wipe down my screen. However it seems that now my call quality is god awful and I can barely hear out of the earpiece. Has this happened to anyone else? I've wiped down my iPhone 4 multitudes of times in the same manner and have never encountered anything like this.
I actually thought the sound quality was excellent before and to have to fall like this is horrifying.
Can anyone suggest a solution? I have a big phone interview this week and I need to be able to hear clearly
Did water get into the internals? Turn off your phone and place in into rice.
Unless it entered through the earpiece, I don't think it did. I really have no idea about how the earpiece is built or if the water would be able to reach the internals via the headphones. Definitely nothing went inside any other opening though....
Wait for the earpiece to dry, its quite exposed up there. Personally I use dry cloth only but if its really bad a touch of water on the cloth can help but not so much as to create any puddles.

Speakers permanently quiet

Since around a week ago, my z3 got water contact. It was not submerged but it was just a water splash. After that bottom speaker sound very quiet. When i do service test the bottom speaker is very quiet. Also loudspeaker calls are very quiet since it only used the bottom speaker for that. I tried everything from putting silica gel on top of the speaker, putting it on rice to cleaning with alcohol. Do anyone experiencing the same? Should i be worried now or there's a chance it would go away. I can't have warranty since this unit was a grey unit

[Q] After replacing the screen, earpiece grill is not working

Hi there,
I replaced my broken screen with a screen+frame which has the grill on the screen. However, after replacement, I can not hear any sound when somebody calls me. I need to use the speaker or the earphones to talk to somebody, pretty annoying. Do you have any idea what I did wrong or missing?
Thanks.

Did the speaker grill have any coating or covering on the inside? Perhaps you either disconnected or tore a ribbon cable that was connected to the speaker (if there was one)? I had similar issues with my screen replacement, but had issues with no cellular signal. I'm going to have to take mine apart again to investigate. I would suggest the same for you...

Hey, I had the same problem when I first replaced. The solution is easy. I forgot to plug in one of the cables which apparently increases the cellular signal. See the pictures attached.
I can not open the grill, for the sake of not opening the screen from the frame I bought the screen with frame and grill. So this defeats whole purpose.
Anybody has any idea about it? Is there a special connection for earpiece speaker?
Are you sure you have the ear speaker installed ? I don't think you have to open the screen to change the speaker.
In step 19 in the iFixit guide they remove the speaker BEFORE they remove the screen.
By the way where did you ordered the screen + mid frame? How is the rest of the quality ?

Hey Thanks for this. I installed it as well but still not working, interesting. I'm going to reopen try to fit it again.
I bought it from here: aliexpress.com/snapshot/6480736262.html?orderId=65692759745232 - DHL sent me the item in less than one week.
There is also alternative: vifocal.com/lcd-display-digitizer-replacement-with-middle-frame-for-oneplus-one-64gb-16gb.html
Quality is ok, I had ghost swipes before. It's not happening any more. Maybe because of software fixes (I'm on CM12 nightly, Lollipop). Apart from that, the colors are a lil bit washed out. I got used to anyways Sometimes under bright light (outdoors afternoon), greens look so weird. Overall I'm satisfied because I dropped the phone a lot in the past and mid frame was full of scratches. Now I have new mid frame.
Here they said the ear speaker is extremely fragile so i think it's
possible you broke it.
How is the speaker connected anyway ? I diddn't find any connector in the teardown.

So it's obviously not the original one :crying:
But contact the seller that you didn't get an original one. You can get a refund. And write him a bad critic on aliexpress that it is not original so he can't trick more people.

it might not be the original one but it saved me from the time without any phones. I gave him a good rating etc. Asking for refund would be unfair in my opinion.
Yes I also saw that xda recommendation, maybe I broke it I don't know. WIll give it a try tonite. Ordered an earpiece speaker just in case from the aliexpress for 6 bucks, but i'm sure it will take at least 1 month to arrive.

Thanks everyone, I solved the problem by putting the speaker unit horizontally 180 degree flipped and it started working.
Nice :good:

Missing piece that goes behind the earpiece, any fix?

I recently decided to fix a cracked screen myself for the first time. It went pretty flawlessly, love how easy it was. Only one problem. I didn't check every part to make sure it was functioning (because it went so easily!), and I found out a couple days after that the earpiece wasn't working. Speaker and earphone jack work fine but not the earpiece. After Googling, I found that a lot of people had this problem, that it was apaprently because there is a small plastic piece that goes behind the earpiece that does something like raises it up and holds it into place against the contacts on the circuit board. Wellllll, I don't have that piece anymore. I contacted LG and according to them that's not a piece they have to sell. Anyone else have this problem and able to fix it without that piece? I'm thinking of just stuffing something in there beneath the earpiece to raise it up, but wanted to see if anyone else had done it and what worked best if so.
Thanks!

In search for new earpiece

Hi guys,
I've dropped my phone in the water a couple weeks back. I put it in rice right after for 24 hours after I opened it up and took out most of the water, which wasn't that much because of my case. A couple of weeks after this my earpiece stopped working so it probably has water damage (no other damage to be found). I just can't find a replacement part. Anybody know where I can get the piezoelectric earpiece module?
Thanks in advance
No one?
Glad to hear the rest of the phone still works. Have you already tried aliexpress?
These don't look right to me from memory, but you'd know better.
If you can't find it, I would try contacting some of the sellers who sell multiple parts for the Mix with a picture of what you want.
