Hardware failure. Replacing microphone. - One (M7) Q&A, Help & Troubleshooting

My HTC ONE M7 might have got some sand in the microphone, which has caused it to cease functioning. I'm trying to determine my next step, replacing the microphone, or selling on Ebay with the defunct mic and buying a new phone.
I've done a few tear downs and replacing Android LCDs, but nothing like this phone. It looks like it requires removing the LCD and hoping it doesn't break and swapping out the microphone.
Don't have the proper tools at the moment, either.
Thanks.

try cleaning it with a pin gently and by not pushing in too far then blow in it really hard. worth a shot. worked on mine

You can buy a new mic module (e.g.: link) so I would assume replacing it can't be that challenging. My understanding from people who have worked on this phone is that the hardest part is opening the case and getting it back together without damaging things.

Successfully removed the back and replaced the microphone, but the replacement has the microphone hole vertical, while the old one was horizontal going out the phone. This seems to be a problem since when the back is in place it now blocks that hole and cannot be heard.

[Help] Camera Replacement Part?

Hello XDA-ers,
My motorola milestone's camera has stopped working for a long time now. I was wondering if there was a replacement part I can buy to fix it. I tore my milestone apart and i noticed that the ribbon is ripped.
I found some places online but I don't know how reputable they are. Anyone have any suggestions?
Any help would be greatly appreciated.
Thanks again,
lilhugo
It sound like a very strange issue to me - could you please describe more how exactly did you manage to rip that flex cable aparat inside of your phone?

Seeing how he tore his milestone apart, I wouldn't be surprised..
Actually....This was a hand-me down cell phone from my brother. He had dropped it, and it got ran over by a car. Thus this destroyed the glass. The glass was held together by a invisible shield, and the camera stopped working as that point in time. I eventually had the glass fixed by a family friend. When he was taking apart the phone to replace the glass, he checked out the camera because I told him of my issue. It turned out that the camera had a small tear in the flex cable. Even though the lens isn't cracked, i'm sure the camera piece is broken as well.
He fixes phones for a living, so I trust him. Not to mention he ordered the replacement glass for me and put everything back together for me. He just can't seem to find the replacement camera part from his suppliers. =/
So technically I didn't tear the phone apart myself, but I was there to witness it and i know it wasn't my family friend's fault.
It was pretty interesting to watch, since I was too much of a wuss to do it myself.
Thank you for the help,
lilhugo
P.S.
The phone works fine, outside of indents in the keyboard. Even the camera app sort of works, but it just shows a black screen. If I try to do anything in the camera app though then it FCs.

Headphone Jack loose contact (Milestone)

Hi,
my Headphone Jack seems to have loosed its contact. I have some basic soldering skills.
But I am asking for some advise from some experts who previously opened there Milestone and did similar fixes.
Are there any Guides on How to open the Milestone to its guts?
Or do you have some advise on what I have to pay attention?
use a small amount of flux jelly on the pins, careful with solder splashes.
hello,
i looked at this video on how to take apart the milestone:
http://www.youtube.com/watch?v=dE81IaQHEHc
and it looks like the plastic cover over the camera gets destroyed during the process.
Is that right? Or can I reattach this peace after the fix?
You have to be very careful. You can reattach all parts using some glue. I had the same problem but its better to buy a bluetooth headset. The s9 hd sounds great!
Just return the phone? Its warranty is valid for 2 years. I did this because of the same problem, and received a brand new Milestone.
if you have warranty send it back, so you can get a new one. Otherwise, open your phone carefully. Everything is reatachable if opened properly
yeah, with warranty it would be not a big deal i think.
You will not believe it, but i have never use my Headphone Jack until now

[Q] LCD + SIM Flex Cable Connectors Broken - Suggestions?

First time poster here and wanted to start by saying thanks to the members on here who have spent countless hours teaching others how to root, unlock, flash custom ROMs, etc. Your guidance has provided lots of fun in the Android world.
Recently, the LCD glass screen had shattered on my HTC One, and I had purchased a replacement front and back. Upon transferring the motherboard + the secondary chip to the new housing, I accidentally broke off the flex cable connectors for the LCD screen and SIM card. Upon completion of reassembly, I crossed my fingers as I pressed the power button, only to be met with the initial power-on vibration and no image on the LCD. Unfortunately, I can't verify if the SIM slot is working without the LCD, but I'd assume it isn't.
Anyway, thanks for listening to my story. I've supplemented it with pictures indicating where I messed up. The first picture is the motherboard. Compare the two connectors contained in the red circle. The left one has the white tab, while the right is missing its white tab. The second picture is the SIM connector to the secondary board. As you may notice yet again, the white connector is missing. If anyone has legit/illegit solutions to this problem, I'd love to hear from you.
Thanks in advance!

unless you have high soldering skills, you should go to a repair shop to get these pcb connectors replaced or even send it to htc. I highly doubt htc will replace the connectors but may replace the entire main board which probably won't be cheap at all.
or the other solution if its to expensive, buy a ''for parts or not working'' M7 from ebay and remove the motherboard to service your phone. (i.e a unit that have a cracked screen but still able to boot) Don't forget it must have a clean imei.
btw I don't understand how you managed to broke that connector tab, it should unlock easily with delicate force with a precision screwdriver..

Thanks for the help, appreciate the honesty.
I'll chalk it up to inexperience, with this being my first attempt at phone surgery. Hopefully the second attempt will go much, much smoother.
Will keep an eye out for HTC One's with a cracked screen!

I know exactly how you broke it off. There's four of those connectors and two of them have a different type of flip. It's silly. I have the exact same problem too.
Did you end up getting yours fixed?

Nexus 7 2012 fix touchscreen issues / grounding issue / ghost touches - HARDWARE FIX

OK, I have found the issue that causes the touchscreen ghost touches, unresponsive touchscreen, etc. This guide is short and simple, and is provided with NO WARRANTY, TO BE FOLLOWED AT YOUR OWN RISK. This guide requires that you open your device WHICH VOIDS THE WARRANTY. Those of us with the original grouper/WiFi/2012 version are well outside our warranties, so that really doesn't matter now.
To explain, our devices use (to my knowledge) an actively driven capacitive touchscreen sensor. It has been narrowed down that a significant number of devices suffer from a grounding issue where the voltage potentials between the case and screen will cause a number of touchscreen issues when the device is electrically insulated from the person touching the screen. There are many YouTube videos and guides on how to diagnose if your touchscreen has this issue; I will not detail those here. To be simple, if you set your device on an insulated surface like a wood table and touch the screen with ONE HAND while not touching the device with your other hand, the touchscreen will go ape**** on you.
For those of us suffering these issues, it can ruin the entire experience of the tablet. I have deduced through a logical process the location and cause of this issue, which I will detail in the guide below.
The nexus 7 uses a filmed metal back, which is mechanically grounded to the motherboard via two "blind" gold spring contacts on the motherboard which touch the filmed metal backing of the case back. I call these "blind" contacts because there is no corresponding electrical contact for them to sit upon, simply the material of the case itself is what they contact when the case is closed.
What you will do by following this guide, is physically break these tabs off the motherboard, thereby breaking the circuit of the faulty ground point. The reasons this is successful in resolving the touchscreen issue appear to be twofold; first the ground points wear off the filmed metal of the back QUICKLY due to flexion of the plastic case back and therefore end up forming a SECOND capacitor on the device case back. This causes electrical potential to build between the plastic case back and the device itself, causing unreliable reading and operation of the capacitive touchscreen. Second, the intermittent ground connection causes unreliable grounding of this capacitive potential, which is worse than no ground at all in the respect of a capacitive coupling of the case back and the device.
These issues could not and cannot be resolved by a firmware flash, because it is a physical problem. Asus could not resolve the issue completely, because even if all components involved are replaced the issue will arise again due to the way the device is constructed. It was simply a poor design.
So, to get to the meat and potatoes of the fix;
1.) Pop the back off your nexus 7. Locate and REMOVE THE BATTERY CONNECTOR to prevent any possibility of a short while you follow the rest of the guide.
2.) Locate the two blind gold spring pins on the bottom right corner as circled in red on my attached picture. Note how they do not have any corresponding connection on the case back as the WiFi GPS Bluetooth and NFC antennas do. This is because these points were meant to found the case back to prevent exactly the issues we are seeing. However due to poor design they have become the CAUSE of the issue.
3.) Most simple step: break BOTH connectors completely off the board by gently bending them back and forth until they snap cleanly off the board. There is no chance of trace damage when doing this - the solder is MUCH stronger than the super thin spring connectors and they will easily break cleanly at the solder joint. If you do not break BOTH off, the touchscreen will get WORSE because you have simply enhanced the ability of the case back to form a capacitive coupling with the case back. So break both, or do not bother.
4.) Replace the battery connector and case back, ensuring you do NOT damage any of the other fragile gold spring connections, if you do you will lose some of your antennas and these connectors are a pain in the ass to replace.
I have attached a picture that shows the two points that need broken off the board circled in RED.
That's it, you're done. Reboot the device and enjoy a touchscreen that actually ****ing works. You're welcome.
Again this guide is provided at your own risk, I am not responsible for anyone who breaks the wrong connector despite my detailed guide, and I am not responsible for any other damage your fat fingers might cause while dicking around inside a sensitive electronic device.
I understand if some are too squeamish to attempt this guide, but I respectfully request that those afraid to attempt do not bother ****ting up the thread with useless posts. Constructive comments are always welcomed.
If this works for you as it did for me (I.E. perfectly) please hit the THANKS button!
I'm also currently unemployed, so if I've helped you and you are better off than I am then donations to my google wallet account are HUGELY APPRECIATED!
Once confirmed, I would ask that the mods sticky this thread.
Post reserved for future use.
And the dumb ****s at Asus tech dept. of course couldn't figure this out. Never again will I give Asus a dollar for anything.

Even if they knew exactly what to do the company is not going to allow them to "damage" devices in order to fix them. That's how Asus would see it, as damage. It is against the original, albeit flawed, design.

They don't do **** to fix anything, I sent them one, a 2012 N7 and they did absolutely nothing to remedy it, re-flashed the O/s or some such crap. I came up with a partial fix myself.
Just out of curiosity, have you done my fix and can you post confirmation so we can get the mods to sticky this thread?
As much as I'd love to get everyone's old n7 for dirt cheap when they think its "broken", I'd also like to see us snub Asus with our own permanent real fix as opposed to their bs runaround they pull until the warranty is up.
So please do confirm if possible.

Hi, Just replaced a broken screen few days on it with a new one and got lots of ghost touches and non responsive spots.
So I tried your suggestion and it works for me , I took a less destructive approach and just put some tiny pieces of duct tape on the back cover where the connectors touch it instead of breaking them off.
My new screen is in place and working properly :good: .
Thanks.

Mods please make this a sticky thread at your convenience, I believe this info will help a large number of N7 users, and it seems like according to the user above that it works when done in a non destructive way as well.
I ve had the same problem with my touch screen, it only happened when i connected the back cover of the nexus( i had a screen change)... so before i try to break the 2 pins i ve just put some electric isolation tape (plastic) and touch works like a charm.... thanks!!!
Be careful what kind of tape you use, some tape could make it worse.
You're welcome.
If anyone else has succeeded using this method or using tape, please post your results. I'm going to assume it hasn't harmed anyone or I'd have heard about it already.
Will attempt this tomorrow and confirm back. Using tape method.
Carried out the tape option, along with other additional fixes. Wipe cache, turn off animations, limit background processes to 3 and others. Seems to be working for me perfectly now.

Can someone please refer me to a YouTube video that shows how to diagnose if the touchscreen has this issue? Thanks.
It's so simple to type into google search "nexus 7 2012 touch screen problem video" you'll need to do it yourself.
Sorry.
Brilliant!
Finally I can now use my Nexus 7. At first I thought the erratic touches were due to the oil on the screen but upon replacing the screen protector, the erratic touches are still present.
Tried taping the contacts with a tape (A simple electrical tape would do), and much to my surprise, the device is usable now.
Also working for me, i just broke the pins. Much better now!
Gesendet von meinem Nexus 7 mit Tapatalk
Tested the tape/isolator option (less hardcode) in my "bad" N7 (the other works flawlessly and they were both bough day 1, maybe different revisions, not gonna open that one incase!), and the ghosting hits and touchscreen ignore problems seem to be completely gone.
Thanks a lot!!
Thanks so much for the fix, it's a new tablet now. I confirm this works by using isolator tape over the pins. Very easy fix, took me 2 mins to do it... would have liked to know about it sooner
Thanks, I already had managed to solve partially the problem placing an aluminium foil into the tablet (risky and complicated so didn't posted), but this is easier and WiFi reception is better too. Anyway it is not perfect yet, same problem than my solution: try crossing axis vertically or horizontally (only one hand, tablet on a table) and weird things happen like no touch detected, very fast touchs, etc... I will post here if I figure out something else.

Bottom speaker replacement.

Has anybody replaced the bottom speaker before? Google hasn't been able to find me any guides on how to do it. Ifixit implies that it is soldered to the motherboard, but another repair site says it can be pried off.

Ifixit is usually right. Also, if something is surface-mount soldered to the board... Yes, you can pry it off... No you wouldn't be able to solder a new one on without the right tools and skills.
I'm hoping it's more like wedged between the board and the grille. Even if it's not it can't be more than a couple leads to solder.
Just replaced it. Very straight forward if you have ever had the phone apart. It is glued down to the motherboard and has contact pins on the backside of it. When I removed the broken one it took the adhesive with it. I used a thin film of super glue to get the new one to stick. If there is anybody else considering replacing the bottom speaker I would be willing to write up a guide. Considering how little info I have found on this I don't think its something many people do.

I have to do the same on mine, bottom speaker not working. Is it visible ones you remove mid frame?
Yes once the midframe is removed it is very obvious where it is. It will be the largest component on the PCB at the bottom of the device. It is held down with some adhesive and uses contact pins for the connection. It was very easy to remove and replace. If you buy a replacement on eBay you may get a damaged one like I did. It appeared dented and crackles when it is installed. I was going to send it back but just never got around to it. I will be picking up another speaker and replacing it again.

Are the top and bottom speakers the same part? I'm seeing tons of top speakers online but very few for the bottom, anybody got a part # by chance?
No, bottom speaker is different from the top. I don't see part numbers listed but if your search term includes lower you should find it. Anything labeled earpiece is upper.
