Nexus S i9023 Replacement Speaker Not Working

Hi Everyone,
This is my first time posting as I am normally pretty good at googling solutions. But this time I am pretty stumped!
I brought an Nexus S i9023 and the speaker on it was faulty. It worked but it hissed and popped and was extremely quiet. Sounded like a dodgy connection more than anything. If you put pressure in the right place it would work for a few seconds.
Hence I decided to go and buy a replacement. I brought the replacement speaker with a new lead on it too from Aliexpress.
It arrived promptly and well packaged. It was obviously brand new too as the flex had not been bent.
I fitted this today but it doesn't work. nothing not a sound.
I put the old one back in and low and behold its hissing and making noises as per usual.
Can anyone tell me if I am missing anything here? Its definitely the right part, It fitted perfectly too.
Massively stumped and if anyone could suggest anything it would be greatly appreciated.
Fastraxs

Cannot think of anything else than to refit the new one and double check the connections...
if you've got a multimeter, measure the resistance (Ohms) across the terminals and compare to the old one, it should give you
a reading of a few Ohms - measure the readings with the speakers not connected to the board - that way you can deduce
if the "new" speaker is in fact good or not

Thank you very much for the advice, my situation has gone from bad to considerably worse! So, I had the original which was quiet making funny noises and then the new replacement which wasn't doing anything. So I decided that perhaps it was just the speaker and decided to solder the new speaker to the old flex and see if I was in business.... exactly the same issue sound was working but very quiet and fading in and out and hissing etc. Hence I thought right then, got this one sorted its the flex. Back to the iron, I soldered the original speaker which I knew was working to the new flex, but still no sound tried a few times as I was worried that the connection from the new flex to the speaker wasn't quite solid enough.
This is where things got....well....rather gutting! The phone isn't turning on anymore. I get the screen light up for a split second, then go dark again. Tried to do all the usual things such as removing battery, tried to get it into boot mode (holding sound up and power), I get nothing when plugged into pc, nothing when plugged into the charger. I am worried that when soldering the speaker I could have bridged the positive and negative terminals and hence made it short. Would this blow my motherboard up? Is that even possible?
I am now at a complete loss what to do now, and before I do any more damage, I thought I would consult the experts. I should also say that it is completely stock and hasn't been rooted or anything along those lines.
Any help, advice, suggestions would be greatly appreciated! Again thank you gunner for your advice it is greatly appreciated, but my situation is rather worse now and I think I have a rather expensive paperweight on my hands.

I'm sorry things have gone to worse mate I assume you've been doing the soldering with no power to the phone!?
If you're suspecting you may have shorted the speaker, I think its a good idea to check that! I suggest to desolder, clean and resolder.
Put some soldering flux if you have any as those little flex things are sometimes a pain to get them attached.
I'm not familiar with the NS circuitry but I reckon a shorted speaker would not result in blowing the whole board! Before assembling
everything back again, check whether there are any tiny bits of solder that may have stayed on the board or to the components.
Clean around the soldered area carefully.
Also, you might want to check if the phone powers up with no speaker attached at all. You might be having another issue as to why its
not turning on.
Good luck and hope you can have it back up and running again mate!

[ FEITENG H9500 ] Known issues and fixes

Ok.. i see many people on this forum asking questions about this device.. the truth is this device is designed very poorly and it even may arive at your hands defective / with some or with a lots of problems.. you can proceed by your very own responsibility. Take a look in the picture for pcb details
- to Fix about every problem you need to findout how to unscrew the back plastic case and be able to see its PCB (Printent circuit Board) - Its pretty easy, just remove the little screws and give a presure at the clips of the cover to be removed, don't use metal objects because you will scratch the plastic.
* WIFI / GPS very low signal
Let me begin with one problem that you have FOR SURE.. is the low wifi signal and gps.. this is due to a horible design of the antenna.. the antenna is not just horrible, but it is also causing a short circuit it self! which is the main reason why the signal is low. First you have to stop the short circuit from happning
How to fix it? Unscrew the back cover, at the top of the back cover under the flash you will see a white sticker, this is the antenna, you have to remove completely this white sticker because it can't be useful by any way. Remove every piece of it including the copper-yellow color from the inside (the place that makes the connection.
Now find a UTP cable and take a piece of a hard copper of it, remove the plastic and keep the copper wire clear, cut it and place it in the whole were previewsly was the white sticker.. you have to place it in this way so it can connect with the inside conntact with the back plastic is placed and screwed again on the phone.. there are 2 pins in that place.. the old antenna used both of this pins (that was causing short circuit) you have to use the left pin and leave the right pin completely empty.. so the right pin doesn't connect anywere, and the left pin is connected to your piece of copper wire.
Cut the copper at the same size of the top of your phone.. so you can place it horizontal ... but you can also try vertical, (use wifi analyze app from play store to see what fits better for you)
Now.. this is the same antenna for gps.. you have nothing else to do.. just install GPS Test app and go outside and test your gps..
This is what i did and im pretty happy with it, instead i used 2 pices of copper and i covered the whole top place of my phone under the camera.. but that doesn't mean is the most right way because when we dealing with antennas there are a lot of math / and calculations that have to be done to design a perfect antenna.
the wire gives really a great signal.. just in case you want to reach the extreme.. Instead of copper wire you can use thin-Copper paper. (don't use foil of aluminium is not good) and design a better antenna copying the design of an antenna from another phone (that you know it works)
* Camera autofocus doesn't work - Or camera doesn't work at all
[Don't unscrew] Frist thing you should try is remove the back cover and give a presure in the right side of your camera with your finger.. this is the place the connector is located.. and it may gets unclipped and loose the connection after a small drop or something. After that Reboot the phone.
[unscrew back] If this presure on the right doesn't fix it, then you have to unscrew the phone.. take off the camera and give it some small hits and punches.. place back the camera and see if it works.. this is due the autofocus motor got stuck.
* Mic, Speaker, USB doesn't work
[Don't unscrew] This is due the connector of the bottom part got lost its connection. remove the back cover and give presure under the place of the SIM cards, were it writes 'WCDM' and 'GSP'. press a bit those spots. reboot, if not fixed:
[unscrew back] The two bottom connectors is 1. for the touchscreen and 2 for the bottom parts.. you need to check both of those because i am not sure which is which.
* SIM1, SIM2, Microsd not working
[Don't unscrew] Try to give some press next to vol+ / vol- buttons
[unscrew back] On the top left of the PCB there are located 2 connectors, 1 is for the front camera, and 2 is for the SIM/SD parts.. the last connector to the side of vol buttons is the connector you have to check and press to make sure is connected ok.
* Touchscreen doesn't work
[Don't unscrew] Give presure right under the headphones jack
[unscrew back] This is were it is located.

Charging Problem
I would like to add the problem with charging the batteries.
I got a new H9500, with two batteries. When i try to charge it with the adapter that came with it, the phone shows the charging animation, but it never actually charges the phone.
I have the same behaviour on both batteries.
After searching for a solution i found these:
-The charger supplied is 5V, 0.5A. Some people used a 1A charger and got to the point that it actually started to charge
-ROM problem, by changing the ROM some people were able to fix the problem, since the software was not getting correct info out of the battery's third pin.
Well none of the above worked for me. I hope someone comes up with an altarnate solution.

I need a new usb pcb for my feiteng H9500 (the usb port is broken on it)
This is the part I need :

Hello guys...
My story. Bought this phone for my son for 160 €. We found out that camera focus didn't work, so I took it apart.
The easiest way to take down plastic cover, after it was unscrewed, is to put something plastic under it in the place between both SIM cards places, and work around inner battery square.
When cover was off, I found out that camera plug (right of camera) wasn't even plugged in. It only laid on connector. Plugged it in, and shake camera a little and auto focus came alive.
After that I noticed that black cable between gsm antenna and PCB was very loose, so I had to sort this out
At the end I found out that speaker connections are very delicate and had to take plastic down again to properly connect speaker.
Now it is obvious to me, why these Chinese phones are so cheap. We have saying in our country: pay little, get little
But now everything is cool and my son is happy.... And I am happy

Hi.
I just got a Feiteng H9500. The problem is that the camera is not working and the camera application hangs then stop responding then quit. When I start the camera nothing apears on display. I've put some pressure then some hits and it started to work a while. The focus worked as well but It seems to me not to work excellent so I gave it more hits, then the camera stopped working again. I have disassembly it, i moved a bit the camera and removed and put back the connector and it came alive again for a while, but just the front camera. Then stopped again. I have noticed that the camera doesn't move up and down when I press on it, it is stopped down, if I lift it with a needle it goes up, so it's not stucked.I can't even comute between cameras because the aplication hangs then quit. ( Everything else works.
any help? Thanks.

Hi Guys,
Just ordered the HTM H9500, is it exactly the same Phone as the Feiteng H9500?
I mean can I use ROMs for the Feiteng H9500 to flash them on the HTM H9500?
Big Thanx

My phone is Feiteng H9500 (HTM).
Appearance is similar FEITENG h9500, but not identical.
I'm not sure that have the same Rom, so I did not dare to flash a custom ROM.
View here:
http://www.movilesdualsim.com/forums/feiteng-h9500.166/

I cannot read Spanish or whatever it may be
There is a ROM at needrom called something like this "feiteng / htm h9500".
That sounds like the device is the same...

Thanks to your photo guide, I found courage and disassembled my HTM H9500 and DG300 phones and fixed them easily (nothing to fix really, just blow off some dusts between camera connectors and in front speaker)

You should order it by the store you got the picture of it. actually there are many stores selling parts for this phone.. almost like its branded.. unlike with other chinese phones you get a struggle to find parts, so you shouldn't face any problem to order a part.

Sound when touch on Lock Screen
hi, guys
I have FEITENG (HTM) H9500 almost a year and I am very pleased with it.
I want to change the sound of the screen when touch lockscreen, but I do not know how.
It did not sound when unlock the screen, it is the sound when you put your finger on the screen while the screen is locked.
In The system/media/ui is not, and I do not know where I'd be looking elsewhere.
Please help

No Data connection
I have had a Feiteng H9500+ for a while but recently rooted it and tried some different ROMs as well as applying a GPS fix. Somehow now my AT&T data connection is not working. The SIM settings have the data on and set to AT&T and I turned roaming on just to be sure but nothing I do can get the AT&T data to work. When I am connected to Wi-Fi it works fine. This is the only way I can get Internet.
Can anyone help me get my mobile data working again?

[Q] Hardware Radio Issues with Nexus 5

I got a Nexus 5 off a friend for a decent price because he dropped it and bent it up a bit. After giving it a quick look, the only thing that seemed damaged was the black little coax wire that connects the main board to the board on the bottom (Assuming it goes to the antenna), The end simply got bent off. This was an easy fix, replace the cable no worries. The real problem is when I went to go test the phone after I fixed the cable, it doesn't get any cellular signal (Wifi/BT still works), draws a crazy amount of power and the 'Qualcomm WTR1605L' chip specifically gets extremely hot, to the point of overheating in like 30 mins. Rather than tossing a bunch of money into replacement components (or getting another nexus 5 with a bad screen or something) I'd prefer to narrow down the problem to one specific component. This leads to my question:
Does anybody have any ideas to how I can further troubleshoot and diagnose this problem, or knows what the problem exactly is?
I have tried a few things, like if I flash the LG G2 radio (A trick I learned I could do with my Nexus 4/LGOG, after backing up my EFS just in case), Wifi and Bluetooth still work while Cellular, GPS and most of the other sensors do not. This stops the big power draw and overheating issue, but doesn't really do anything to further identify the problem component. I noticed that the modem image could be mounted as vfat and you can mess around with the various parts of the image. I don't know which files do what, so I have thus far left it alone.
I know this seems like an odd question to ask here, half the time I see responses like "Send it into Google/LG and have them fix it for you" but that isn't really applicable in my situation
Also, I know that my SIM is good, it works in my Nexus 4, I know that my ROM isn't a issue, because I have multirom installed and tried many different roms. The Radio image shouldn't be an issue because I had updated the phone from 4.4 to 4.4.4/L Preview since I got it (Using the google images and flashall script). IMEI/Whatever the ESN equivalent shouldn't be bad, my friend had been using it before he dropped it.
Thanks in advanced for any ideas, and sorry for the long and comprehensive almost to a fault thread.

Dropping a phone can sometimes cause invisible damage (like BGA solder joints failing). Visual inspection can only tell you so much.

I used to build small electronic projects when I was a kid. When something overheated like that, 90% of the time it was a short or a the wrong value of component. It's possible the drop caused the antenna connector to short out. Try disconnecting the antenna cable and try again with the stock radio firmware and see if the radio continues to overheat.
(I'm not sure how flashing the radio would prevent overheating, unless the original firmware simply turned up the transmit power in an effort to contact the tower, but that's my first guess and should an easy thing to eliminate).

Thanks for replying! When I get home I will give it a shot and see if it still overheats, then update this with my findings.

If it is overheating then it must hardware issue. Worst case is that the PBC board has a crack somewhere because of the bent. Grab the service manual from the general forum and start mesuring the components to find out where is the problem.

It seems to overheat with our without the antenna cables on the stock radio. I noticed that it still gets warmer than it should with the G2 radio, it just takes a lot longer.
That service manual is really comprehensive but unfortunately, it is going to take me some time to actually get to looking it over closely.

Just had to share this experience....

Well I have been a owner of a LG Nexus 5 for the past (almost) 2 years now, in fact I am coming to the end of my contract very soon and will be able to either goto another company or get a new phone.
Anyways, sometime ago I experienced a problem with my microphone and external speakers not working, or at at least some of the time... After a bit of research online I found out my problem was related to a connection inside the phone that connected the bottom assembly to the main board at the top of the phone. It required me to remove the back panel and a few screws to remove the plastic cover, but the poster suggested putting some tape on top of that connection to hold it down more firmly to the socket it connected too. So I did this. I put some black tap (electrical tape cut to fit.) on top and then assembled the phone again. Viola, It worked!
Well, a short time after I decided that I wanted to update my phone from stock kitkat (4.4.4). Always been curious about custom ROMs and gave Cyanogenmod a try. Not only that I got bold and tried the nightly releases of the new marshmellow update. After some time I started experiencing things not working, like the camera, and a lot of freezing, hang ups and random reboots (not so much the reboots as the constant freezing). Often I couldn't get anything on the screen or the phone to respond from a locked state and when I did, often the phone would lag so much, that doing anything would take a long time and proved to be impossible.
I started thinking it was the nightly releases as the source of my problem and just kind of shrugged it off and figured "they will eventually fix the problem". I kept this thinking for quite some time. But it occurred too me one day that something else was causing the issue I was facing for the simple fact that the lag started showing up in the recovery mode (also custom) and a lot of times would continue to show up after I rebooted my phone. Hence, would rule out any 'software' issues I was facing.
I began to think that my problem was hardware. Maybe it was just time for a new phone. But still months away from the end of my contract, this meant I would have to pay off the 'problematic' phone first before getting a new one. I really didn't like that idea. So while looking into this problem, in a last ditch effort, I opened my phone again. Dunno why but I also decided to get rid of the tap on the connection I tried to fix before... I popped off the connection there and had a look at it. It didn't seem damaged in any way nor did the socket. Strange as it was I put that connect back in the socket and put the cover plate back on making sure not to torque the screws and assembled everything back up....
Now the mic and ext speakers work just fine and the phone is working like I just opened the box and took it out for the first time. And I have not once seen any problems... I understand what's happening here... still just wanted to share that for it was definitely weird or what?

https://drive.google.com/open?id=0B0pUNVcVRCJ7MThMc0NHLUNkSEU
Sorry about the link, only way I can upload an image.
Just so there is no confusion... an image of the effected area, inside the phone. The arrow points to the connector and more importantly the area of the connector that seems damaged. If I press lightly where the arrow is pointing on this image, the assemable at the bottom (speaker/mic) will work, indicating a loose connection. Although after visual inspection, I cannot see any damage to connector or the socket. I suppose the only way to really "fix" the issue is to order a new part. As stated previously, already tried tape on the socket to help hold it down, but that seem to cause just as many issues with the phone performance. Any other suggestions?

When ordering a replacement part, you need to be careful because there was another XDA member replaced the same part with a cheap 3rd party solution and the phone would not charge until he replaced it with an oem part.
http://forum.xda-developers.com/google-nexus-5/help/to-buy-usb-charging-port-flex-cable-t3314357

Does anyone else have issues with there ext. speaker and mic not working?
An update on the phone;
back to square one. My ext speaker and mic will not work. And that socket has something to do with the LCD connection on the screen as it will black out if just the right area on the back of the phone is pressed. Only way to revive the phone is to long-press the power button for a reboot. Then will come up fine but speaker and mic still do not work.

Wow, that sounds pretty low level tactics of LG... just shameful really, but not hard to believe these days...
Quite honestly, I am just going to replace the phone. Think I got a pretty good run out of it and think its pretty well time for an upgrade. Anyway, for the reason I got the phone, it wont matter the speaker and mic don't work. Just going to use it for development and it will be a good test device.

Oh an this post is related to this thread so I thought I would link it for it may help someone else facing similar problems....

I'm not sure that LG had anything to do with the low-quality replacement parts.
If I were you, look for a n5 with a smashed screen that is suitable for parts.

Good idea, except the iphone is the most popular phone around here ... find it pretty hard to find one, been looking. But thanks.

I have seen quite a few busted n5 phones in Toronto. I have managed to get working phones with a smashed screen for as little as $30 which is rare for Toronto. Average I pay is $40 to $50. For this price, I either use the phone for parts in several phones or I get third part screen from Aliexpress for around $40 CAD.

I just want to update this as well...
I am fairly certain (now thinking about causes) its not really a design flaw, but more so because I frequently sat on my phone when it was in my back pocket...

It was not me but I had that same experience. Replaced with a cheap oem and it didn't charge after that.
I found out why. The charger usb socket was not connected to anything ! Unbelievable! It lacked the black plastic backing for that part of the cable to connect to.

dual Screen bad connection, maybe solved with wedge?

My dual screen case has been playing up, about 90% of the time i clip on the case the screen does not work after a few minutes due to movement.
it seems LG has made a bad design with the usb c connection and poga style pins at the bottom of the phone would have been better long term.
My solution : I have placed sticky tape as a wedge at the bottom which seems to be working for a few days now but not sure if it will last. the wedge lifts the phone away from the case's usb c male plug enough to allow some flexibility (I think).
Otherwise, i have twisted the case and it works but that might just slowly destroy the usb c plugs structurally.... whereas padding upwards hopefully won't cause damages.
Taking the case off afterwards is much hardier with the wedge but i don't need to remove case much if it actually works.
let me know if it works for you guys/gals.
you suck LG for such an unreliable connection design, and don't even talk about the magnet charger tiny adapter bit!

Too bad you're having issues. I haven't had any at all. I use my dual screen case maybe 25% of the time. Generally every night and most weekends. Had the phone since June.

ok maybe mine is defective, but ive only detached the case a few dozen times and its definitely damaged... the wedge has fixed the connection really well, days now and lots of movement and still no issues, screen working great, knockOn working and charging is good.
although attaching a few usb c hubs won't activate hdmi, only charging, but without the case, the usb c hubs works and outputs hdmi fine.

You phone is under warranty. LG will fix it. I'd you registered it it extends the warranty for a second year even.

i got it from another person and can't return it, its working great now, no connection issues at all.
i see lots of ppl complain of this issue though.

I had a similar issue with the dual screen case on my G8X. Suddenly it started getting random ghost touches on the second screen and turning on and off by itself. I returned the dual screen case and got my money back because it hadn't been a month since I bought it on eBay. I was gonna buy another one but decided to upgrade to a V60 instead.
I didn't think of your method @gary776677, but now I wonder if it would have worked...

still working and have taken off the case many times now.

It works, really!

I just got a 2nd v60 as my first was an AT&T (you can never properly unlock those and get android 12). So I put the new one in the dual case and...nothinh. Old phone works perfect, every time in the case.
Saw your post and solution and it gave me an idea.
Measured both v60s...guess what...they are NOT the same size! No wonder there is an issue with some and not others. The volume switches don't even line up.
Will be trying your fix. Thx
