Cleaning P20 Pro loudspeaker - Huawei P20 Pro Questions & Answers

Hi to all,
I was cleaning P20 Pro loudspeaker near USB C. I pulled the toothpick in those holes. And everything is OK. But now im scared did I Damaged mesh that keeps water enter to phone.
I think the i didnt see mesh in some holes...
P. S. And can you check on your P20 Pro when you playing some music at high volumes, put your finger near left then right 5 hole's. Did you feel how right speakers "blowing". Is this same thing to you?

I think on this photo I see the some black mesh are like broken. Are this first black mesh for for dust ir for water resistant?

can't confirm 100%, but its likely just a mesh for the dust. the speakers themselves will have an additional seal around their edges

[Q] Broke the exterior speaker, need some advice.

So I dropped my nexus today, everything looked ok it turned on and no cracks or anything. But I was using the gps later on and it was making weird sounds. Then the speaker just stopped working. I figured out that I broke a connector on the speaker cause when I press down on the center of the speaker very lightly with back end of a pen it will make sounds.
Can I fix this speaker or should I replace it?
For those of you who have taken apart a nexus how difficult is it to replace the speaker?
Any other advice is welcome too.
Super easy to change the speaker.
Yeah, extremely easy. Remove sim, remove MicroSD, and remove 3 screws from the frame around the battery (2 TORX, 1 phillips). Then use a plastic pry tool, used credit card, or fingernails to pop the plastic frame around the battery up. There are clips along the edge between the metal and plastic frame. Once it's up, pull it out as part of it is tucked under the metal bar at the SIM/microSD area. Speaker is press-fit into the frame. It just makes contact to 2 gold posts with 2 tiny gold springs. Maybe one of those just got dislodged and can be bent back into place, but you can just push the speaker out of the frame to replace it if it's defective.
Thanks for the help, I'm gonna order a replacement speaker and fix it my self.

SOLVED : Lower speaker clicking after re assembly

Hey guys,
I just swapped my silver one to a black shell.
Very simple change over for the most part.
Prior to snapping the back cover on, I made sure to test all functions. They all passed fine. I then snapped on the back and rebooted the phone. The lower speaker no longer played any audio, instead just clicks until the sound finishes. It's incredibly annoying during speaker phone calls. Any idea what it could be, or better yet, is there an app that can force the phone into mono mode with only the top speaker working?

Alright, took it apart again and inspected it. Found the problem. at the base of the phone there is a ground clip that covers and grounds the usb board to the main board. Directly above that there is a very small connector with a black and red wire in it, those are your lower speaker connector. when reinserting it into the back cover the red wire moved onto the ground plate and wormed its way between it and a spring clip that ground it to the back cover.This spring clip applied enough force to lightly cut the casing thus grounding the positive speaker feed to the phone case. Kinda a b!tch to fix, full disassemble is needed to pull that board out, i then used liquid electrical tape on the damaged spot. Let it dry and reassembled. Now its black and perfect!
I attached a photo of the red wire and its location. Be careful with this area, I was lucky the board or phone didn't short out!

How did you even get it apart??

Carefully and with a bit of swearing. The back cover is actually dead simple to take off, if it wasn't for the damned adhesive on the sides. Be prepared to need a new rear cover.
I used 3 different thickness guitar picks and a plastic pry tool ( those blue guys you get when you buy any part out of china). I would recommend heating up the sides to start, if you have a bean bag heating pad, use it, put it in the microwave for 2 mins and sit it on the sim card side of the phone. Because the plastic is a little flexible, I was able to slip a pick between the screen and the sim slot, then pry it upwards and slowly slide the pick toward the bottom of the phone. Once you get a little ways down stop and leave the pick in, take a thicker one and to the same, replacing the first with the new one. Repeat with another, the trick is to apply light bust constant pressure on the glue to break the bond. After a few mins of that and possibly reheating, you should be able to go around the corner and across the bottom. The glue is only of the sides. There are 4 clips of each side and 2 on both the top and bottom.
Make sure that the top assembly comes out from the bottom of the phone first or you risk damaging the power button/ir blaster.
I bought a full screen replacement with back cover from etrade, I also bought an empty shell from eBay, I used the etrade parts, but I'll swap the original screen to the ebay parts tomorrow.

I was too, I watched videos, I read the forums. In the end I just grabbed it and tried to see If I could even fit the first pick in, then I got farther and finally got it off. The guts are simple to change over, just be aware that the screws are not interchangeable, so take a piece of paper make notes and keep track of your screws. When I got it rebuilt I was bumbed out at the speaker, but because there is no glue on the new free I was able to get the back off in less then a minute.
I see no gaps or problems. Everything works and the phone looks great, in my opinion they should have never made a white and silver. I'll post some picks when I'm back home tonight.
I followed the videos from Go Cell Phone Repair, he has 2, one is the tear down the other is the reassembly, Google YouTube for them, he was very thorough.

Upper Speaker Issue

I recently bought phone. Since there is no screen protector for note 9 in my around, i temporary plug a protector for note 8 with nano luqiud with glue and uv light. Problem is does note 9 speakers give both same amount of db and my phone's upper speaker went a little less powerful since liquid leaked into speaker. Or It is normal to upper speaker have a little bit less sound? Sorry for my grammer.
If you spilled the glue into the speaker it will probably sound lower than normal. I don't notice a difference in loudness between the top and bottom speaker.
The upper speaker pushes less db than the main firing speaker. The waterproofing fabric for the speaker is deeper inside than the Note 8. If you look in with a light, you can see a gap between the actual grill and the waterproofing fabric for the speaker. If glue got in there I'm afraid the only way you can get it out is by taking the device apart.
Also, with these type of speakers and the waterproofing material being used, once liquid touches the fabric, the sound is dampened out because there is no longer free vibration of the fabric to let the sound travel, aka sound "loud."

Use some alcohol and a tooth brush to scrub out the glue. Then, blow it out with a can of compressed air. accidentally got some glue in my S9+ doing a rush job and the speaker wasn't as loud. This rectified the problem. You may have to scrub and spray repeatedly a few times, but I managed to get mine cleaned out.

Using compressed air, make sure you don't damage the top speaker's delicate diaphragm (the extremely thin material that moves and creates the sound). If you tear or warp it, the top speaker quality will be worse, and sound distorted. It happened to my friends S9 when he had water in it from going for a swim and forcefully blew in it with his mouth to get the water out. It never recovered.

why would you want to use compressed air to push the water even more in the device/part again?

[Q] Both Mi8 Speaker and Microphone Grill have mesh ?

Greetings Folks
I got my Mi8 Global used but in immaculate condition the only aesthetic I found odd was the speaker grill on right it doesn't have the grill mesh like the one on left side before as my phone is in Black and I didn't notice much but today I was cleaning my phone up I noticed the tooth brush went far in on right side (phone up faced) the speaker side but I could feel grill mesh on left side
My question is all mi8 are like that or I got it this way?
If it's just my phone maybe previous owner poked then for rattling sound often caused by water sealed phone (sure our phone doesn't have a IP rating but we all know Xiaomi and Oneplus both have designed mi8 and op6 keeping tht in mind

Question Muffled MIC full of dust ultimate cleaning solution discovered...

So I discovered this trick a few weeks ago and I have been meaning to share with everyone but only got to it now.
The top speaker on my old S9+ was crackling when playing music and I decided to try and clean it. I put alcohol on an earpick and rubbed it in rounds, up, down, left, right and etc. The sound got better but not enough. Then I noticed the hydrogen peroxide 3% next to the bathroom mirror and used it instead of alcohol. I also decided to play a loud song at the time of cleaning it. As I was at it, I could see little bubbles flying off from the speaker grill and opening up all the tiny holes that were filled up with gunk over the years. This process restored the speaker clarity to 100% as original.
Then, since both mics of the S9 were muffled from all the dust (and likely baby powder from me powdering deez nuts as it helps with comfort ) I decided to fill them up with peroxide as well, instead of alcohol. I took a fat needle and was putting it up and down into the mic holes to push the peroxide out. While it was coming out I could see it bubble which is an indicator that it is dissolving particles. Then I tried it with paper and added some more peroxide and repeated 2 times.
Last, i took a dry earpick and pulled the cotton up while rolling it with my fingers to the point it became like a long fat cotton needle. Slim enough to enter the mic holes as I was turning it and pressing it slowly inwards. Did that part to absorb any peroxide leftovers, instead of waiting for it to dry out by it self.
The result was crystal clear sharp sound that I had thought was long gone and never coming back. I call this a full restoration.
Did the same thing with the s21u on all 3 mics and it worked splendidly. 2 of them had become somewhat muffled after a years use and when talking through the loud speaker people on the other side weren't hearing me clearly.
Note 0: To put peroxide into the mics, I fully soaked an earpick with it and then gently rubbed it on the mic holes until it went in.
Note 1: Putting a needle in the mic holes will not damage the mics as the holes are curved so the needle cannot touch a mic. (Samsung's preventative measure against people putting in the SIM pick in the wrong hole)
Note 2: You can test your MICs clarity through a sound loop by opening your dialer and typing *#0283#
Note 3: DO NOT attempt this on phones which are NOT waterproof. The only reason this works on our phones is because they were designed to withstand water.
Ingenious. As long as the water or oxidizer doesn't damage anything. That's a tough cleaning challenge many times.
If any of it makes it past the mic inside the phone better be ready to pull the rear cover, disconnect the battery, flush anhydrous isopropyl alcohol (min 93%) and completely dry.
I was wondering if there is a technique, when cleaning, to avoid pushing gunk further down into the mic which would clog them even more?

Legit points, thanks god peroxide doesn't really affect anything rubbery or plasticky.. And given that the phones waterproof rating says it can withstand water pressure of about 1 meter's submersion, all should be good as applying little drops of peroxide puts no pressure at all.
But yeah, it is a bit scary for sure, aaand totally worth it once the sound clarity is restored

Yeah it's tricky. Best to clean it regularly a microfiber cloth before the junk gets pushed in.
A dry climate helps as does not putting the phone to your ear.
After over 2.5 years my N10+ ports are surprisingly spotless. They are partially shielded by the case which is antistatic it seems.
The Bolt case rarely requires much cleaning, another reason I wuv it.

That's exactly what I had been afraid of when it comes to cleaning with alcohol.
The thing about the peroxide is that it starts bubbling up the gunk and essentially it helps is dissolve and carries it upwards. If the gunk has muffled your mic, it has already piled up at the bottom... No further down to go haha

Yea I live in the Mediterranean and during the summer the humidity can reach up to 90%+.. And in the winter I have the phone playing music in the bathroom when showering and the air fills with steam from the hot water.. Too many no no's...

Yeah just saying. Never trust that waterproof rating; it's waterproof until it leaks
The ports, mic and speakers are probably safe but the rear cover seal and buttons are suspect so try to avoid getting liquids on those.
