[SOLVED] Replace Defy Earpiece

Hit post #11 for a walkthrough on replacing the earpiece.

Funny but kinda looking for serious replies as it is quite important

Nokia AAC-0510 seems working. (Chinese) http://www.itfunz.com/thread-84490-1-1.html

Somewhere on this forum is a link to a Russian blogger who pulled one apart and (apparently) swapped out speakers.

post #157

Just to report back i received the k850i earpiece today and successfully replaced it with the original one from the Defy, works perfectly and no modding at all except flattening the terminals slightly, its a very snug fit but is working fine and is much clearer than the original one in terms of call quality. Maybe the mods could sticky this or something incase anyone else has the earpiece problem. Total cost of repair £1.99 for earpiece and about 30minutes of my time !! much better than sending to motorolla for weeks on end in my opinion.
Cheers

That is great info to know! I am more confident in getting a Defy now knowing I can fix it on my own.
Any guide with pictures for us?

well done wizard123
i hope i will never have to do what you did with your speaker but... who knows?
yes a detailed guide with picture and tools-to-use would be a nice idea - really useful for all the people who void the warranty

A quick question...
What's the waterproofing situation like? Is there a membrane between the earpiece and the outside world or is it built into the Defy earpiece?

No problem guys, i hope you never have the issues but i know it did hit alot of people including me and motorolla claim mines was out of warranty being only 3 months old ?! but hey i dont have time to argue or mess about as i need my phone.
I will try to get some pictures up but in the meantime follow these steps it is so so simple :
1. Remove battery & SIM card
2. Remove the 7 screws from around the phone casing and the 2 silver screws underneath the back cover. ( You will need very small torx bits )
3. Separate the two halfs of the casing, ( very stiff and fiddly but dont be affraid to use a little force )
4. Carefully lift off the 2 connectors on the main PCB board and lift it out ( careful not to lose the yellow rubber washers )
5. Use a small pair of pliers or long nosed pliers to gently grib either side of the earpiece and slowly wiggle side to side untill it comes loose and lifts out ( This takes patience as it is very well glued in but does free off )
6. Take your new K850i earpiece and place into the slot with the two springy copper terminals facing up towards the top of the phone ( you dont HAVE to but i did flatten the terminals a little bit so not to bend the PCB board when you place it back in ) having the springy terminals on these earpieces placed the correct way up creates a very solid connection to the board too unlike the original earpieces which dont have any at all just flat terminals.
7. Return the PCB board back into position and reattach the 2 connectors removed in step 4.
8. Return the casing back into place and install all the screws ( dont forget the 2 SILVER screws FIRST, these hold the PCB board down to the casing and hold the connection solid to the earpiece )
9. Place SIM card and battery back in and boot up your fresh earpieced Defy
Pictures to follow soon hopefully

There IS a tiny tiny membrane between the earpiece and the casing and does appear that it would still be waterproof but i have yet to test that and not sure if i will as it is a BIG BIG risk lol ( maybe though hmmm )

Thanks for that.
So the membrane stayed with the handset casing through the procedure?

That's interesting. Maybe the failures are caused by poor connections in the first place. Perhaps a pre-emptive strike with some electrically conductive paint would save the day. It's claimed to function as an adhesive.

Yes only the earpiece came away from the casing using the method i applied but again i can't swear by the membrane as it could possibly be different with other variants of the phone ( although i doubt it ).
And plus for me atleast, i'd rather have a working phone than a waterproof phone ( just me though )
I am nearly certain its an actual defect with the earpieces because if you blow the earpiece with some canned air it will function for 5-10 seconds before going off again.
I do think there may be a problem with both the connections and earpieces though as the way the oem connections are designed in the Defy for the earpiece contacts are piss poor, excuse my french lol.

Well, I'm sending my Defy in for repair today, after my earpiece started playing-up intermittently over the weekend. I tried to insist on a replacement but Motorola's support team were adamant that a repair is my only option under the terms of my warranty. Ah, well. I've got a spare phone.
That said, I will likely "paint" the earpiece connections upon its return and it's good to know that the K850i part works. I may buy a couple as a precaution.

That sucks man sorry to hear that, it seems to be not if it will happen but when it will happen with these earpieces, yep motorola sucks for customer support to be fair. I hope your phone comes back ok though, alot of people have had it repair only for it to fail again a few weeks later.

Can I just double check which seller you got yours from as I've had a look on ebay & the three that are for sale look different styles - unless the pics are not of actual items?

The actual one i used is this one :
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=300370841729&ssPageName=STRK:MEWNX:IT
There is an actual motorola one that has the same terminals as the original but ( my opinion i would not trust another earpiece from them ) :
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=220640434368&ssPageName=STRK:MEWNX:IT
I wouldnt worry too much if they look slightly different aslong as they are for the k850i as it will most likely be because they are from different manufacturers
Hope that helps

That's great thanks very much
Might just order one to keep as you never know when it'll stop working.

I had my earpiece replaced by the company, you should really send it to motorola and don't mess around with the device.

Echo problem

All my callers are saying they have any echo when they are on the phone with me. Narrowed it down and it appears to be due to the bottom microphone on the phone. My new case apparently makes it go crazy even though it has a hole for the microphone. My other cases seem to have no problem. It's so weird this case does when it has a hole for the microphone larger than the other case. Anyone got any thoughts other than tossing the case? Could it a microphone problem?
Sent from my SGH-I747 using xda app-developers app

So when you make a call without the case on it's fine? If so before just getting rid of the case you should try cutting the hole out bigger or something.

Is it covering the top microphone? This is used for noise and echo cancellation, if you have this enabled in Phone's settings. If it is covering this, try toggle the feature off and see if it improves.

odd problem, had the same issue, with speaker phone and bluetooth.
you know what it was (on my behalf atleast) the SIM, went into the AT&T store and got a new sim issued..
weird.

I have traced the problem down to being the bottom microphone on the phone. I did this by covering the bottom one with the case off and it produced the echo on the other end of the line. When the case is off, there is no echo. When you put it back on it is back.
The hole in my case is pretty big for both microphones. I don't see what making the holes bigger will do. It really has me stumped. I did research on the web and it turns out this is pretty common in Galaxy phones. However, there is no good solution.
Some folks just stop using cases. Others got a new sim as you alluded to. Others it started working better. And some just returned their phone.
On the SIM card issue, did it matter if you had a case on your phone or not when you had an echo? Since mine is related to the case and microphone, I wonder if the SIM would have any affect?

it would be worse if i put the person on speaker phone.. so i dont know how it could be the sim, (with or without a case) but it worked better with new sim.

possible fix for echo problem
This may be worth a try to fix your echo problem. Open her up and pad the mic.

Galaxy Note 3 Mic issues

My galaxy note 3 mic doesn't work when I try to talk on a call or using Google now. It does work when I record a video so I am wondering if there is multiple mics and what mic would I need to replace for talking on my phone.
Thanks!

Have you contacted Samsung support? If a mic is not working it sounds like a hardware defect.

Same problem - How I resolved it
Sorry for bumping a kind of old post, but anyway...
I had the same problem with the mic not working on my note 3 since the day i bought it, I bought my Note 3 used off Craigslist, and when I got home I realized that the microphone didn't work on calls, but worked just fine on speaker phone. I was somewhat annoyed by this, thinking I got screwed on craigslist again. But instead of throwing a fit about it, I just ordered another charging port / microphone thinking that would solve the problem. I installed it when it arrived, all excited like, only to find out that this didnt fix the problem. I read several posts on this forum and others, many offering what seemed to be viable solutions, disabling noise reduction, cleaning out the mic hole with a pin and so on, none of these worked, the problem still continued.
So tonight I set out on a mission to find the cause of the problem and i did just that... I started by taking my phone apart so that I could clean the mic hole from the inside as well as cleaning the little screen / filter on the inside of the mic hole and stuff like that, I was working in an area that had awkward lighting (my patio), and so I was having to move the phone in different ways so I could see down around the microphone, while doing that I noticed the light glimmering around the area of the mic hole, on the inside, I looked a little closer and I could see that there was definitely something there. I picked at it with my tweezers and what came up, a piece of clear plastic that resembled the plastic you find wrapped around the edges of new electronics, it was about 1/8in wide and 1" long, and it was covering the mic hole.
After removing the plastic, I reassembled my phone and tested it, now the mic works great. it seems that samsung put this thin plastic there to keep things out of the microphone, and it works well, it keeps everything out of the microphone, including the sound of your voice..
Now my Note 3 is what it was supposed to be from the day I bought it, an awesome phone. Prior to tonight its been a regretful purchase and disappointing upgrade to my Note 2, which I had regretted getting rid of, until now...

Hi, thanks for great troubleshooting.
I was hoping you have a picture of the problem area, since I have an issue with my speakerphone. People cannot hear me properly when on speakerphone. I may have to fix the microphone as well on my good old Note 3.

Back cover crackling

Hello everybody, I've just bought this phone yesterday and I already have a problem. I was using my phone and suddenly the back cover started making noises when pressed in the battery area and sim/sd card slot area. It's looks like the cover somehow won't attach itself completely on the left side where the microusb port is. The right side seems ok except at the bottom where it also makes that crackling sound. For now I have fixed the problem by putting paper between the cover and the phone, but that solution is not really practical because I will have to repeat the process everytime i remove the back cover.
Any ideas what could cause this?

It's just weak build quality, mine has the exact same problem.
This isn't exactly a high-end device afterall.

So no way to fix it unless to replace the cover?
I might just go buy a replacement cover, the squeaking is driving me nuts.

Putting a piece of paper inside the cover should mostly fix the problem.

Phone heats up when back cover is on

Just replaced the screen on my Oneplus 3, and everything works fine except that the phone gets insanely hot (easily 50C on the outside of the back cover) when the back cover is on. When I removed the back cover however all parts of the phone are cool to the touch when it is powered on. Anyone know why this might be? Is the back cover shorting something out perhaps?

Since the covers are not metallic, I don't think so. But it is possible that the cover is compressing an area on the phone which leads to a short circuit.
Try a softer cover like a TPU.

Sorry for the misunderstanding. Obviously, it is the positioning of the internal components (which should have been disturbed in your case) that cause the short circuit when the back cover is put on.
If the screen was replaced by a technician, it is better to take it to him. If you did it yourself, try troubleshooting with all the exposed components on the back.

Yeah, I managed to fix it by putting electrical tape over some of the connections (likely used for antenna reception) which lead from the motherboard to the case. Now it is just a matter of trial and error to find which of these pins are causing the problem. I seem to have blocked the connection from the Bluetooth antenna though as the connection is really weak now, but that is a very easy fix

You'll most likely either have fixed it by now, or thrown the phone out the window, but hey!
Mine was sort of fixed, but the touch was still acting up so I sold it as "not working" and bought a new one. Can't remember which pins I put tape over, but I assume they wouldn't be the same for two people anyway. It seemed really random to me at the time.
