Hi guys, yesterday I've repair my broken d802 (headphone jack broken) and everything goes fine.
But, while I starting to close the back cover I've notice something strange:
a lot of paper clip and needles I have on the desk start to get attracted by the phone, in a first place I thought it was normal (speaker has a magnet) but the magnetic field is near the camera.
Also with the back cover on, it still attract a bit paper clips.
It is normal?
Does your d802 do the same?
the exact place is just some millimetres above the camera.
Thank you in advance
Mine does the same, must be some component that causes this..
so it's not my fault while I was trying to replace the part
Don't think so, but I've previously replaced my screen so it could be different from original parts?

Hi,
The speaker on the outside of my universal (the onw you hold against your ear with when the screen is on the inside) is broken.
That started as something like a bad contact (if I pressed the phone against my ear it would work, otherwise not). Now it is not working at all.
The speaker on the LCD side is working fine.
The advice I want:
I took a look at the service manual PDF I got and disassembling the phone to reach that speaker is a lot of work. I do have experience with diassembling electronic devices and even do some soldering, etc. However, my doubt is this: I have a phone which does work, but the way I like to use it to make calls does not work.
Question 1
Is it worth the trouble to diasassemble the whole device just to check if it is indeed a bad contact due to i.e. dirt? Or will I actually risk breaking something off, which will render the complete phone useless? Looking at the service manual, one needs to use a plastic tool to actually open the phone. How easy do the hinges break off?
Question 2
Has anyone had a similar problem? Was it easy to fix?
Thank you!
Cheers,
vma
you dont need to disassemble the whole phone just disassemble the screen . It isnt that hard to do, just remove all the screws from the screen . The screen casing is difficult to budge at first but once you have freed part of it open, the rest follows quite easily.
Hi,
Meanwhile I couldn't resist and opened it...
...and I found the guilty part.
It seems that the outside speaker is actually attached to the case and uses a contact connection to the PCB. This connection is made by to metal plates, which are tiny and folded. They will compensate the varying pressure made on the case (i.e. when you press it) and I guess with time they tend to break at the fold.
This happend to one of the two contacts. First I tried to fix it, but the truth is that it is so small that it is quite impossible to do anything about it. I considered soldering a small wire, but that would require to solder the other end to the pin on the PCB, which then would mean, I could no longer use a regular replacement speaker, if this one had any other fault (unless I could clean the contact again, but trying that, I could break something else, also).
This means: now I am not able to use the outside speaker anymore...
Question: where can I purchase a replacement one? Would anyone sell me one from a broken Universal (for a symbolic price - anything over 10 Euro is too much, as I would prefer to just buy a another second hand Universal)?
And as I was figuring this out, I used the occation to fix that loose stylus!
1) Open the underside case (4 screws, then open the case all around with some thin plastic).
2) Roll a little bit of celotape and place it between the case and the pin that fixes the stylus in position.
3) Try it out until it is OK.
4) Close the case and that's it!

Hi buddy, in fact I did have the same problem that you're having some months ago, my uni fell and since then the problem just got worst, until some day a couple months ago I opened it and fix it.
It's just like you say, the little golden plated contacts wore off, then the little speaker's metal plates just were too high to make any contact against the pcb, it's really simple, just pull the plates gently away from the little speaker, do clean both sides of the contacts (pcb and speaker's plates), i did this with a little xacto knife (be very gentle), and that's it! It worked just fine.
The problem is that in my case one of the metal plates broke off.
I tried to fix that, but it is to small for me to achive anything.

Hello People,
I've got a little problem with my hd2 ^^
Since several weeks, the plastic from the LED's was pushed inside the device and so the vibration alarm wasn't really silent anymore (since the vibrator is behind the led plastic and it touched it inside).
So now I decided to open the device an push the plastic back in it's place.
Opening the device was really hard because of the massive glue they used^^
But after some minutes I got the electronics out of the body. I cleaned it a little bit up, fixed the plastic an put the device back together.
Starting it, confirmed that the vibration now works silent again, but my screen stays black...
I really don't know what happend there , but I never touched the screen or openend the device more than I had to.
So maybe anyone has an idea?
THanks a lot.
First thing is that i dont understand where you finded "massive glue" if you just opened your phone to place back leds cover/zoom plastic. They dont use glue, only adeshive stick tape. But this is just interesting for me.
Second thing is: are you used some minimalistic bead when you placed back leds cover/zoom plastic? If you didnt, then it can drop again to inside.
If your screen is black then maybe you just acidently touched connector and ribbon cable, where lcd connects to motherboard. You must open your device again and recheck. This connector attached with ribbon cable at lcd must be sealed with yellow tape.
Hello,
sorry a meant adeshive stick tape ^^ I was just hacked off when I wrote this
yes, I put something on the led plastic.
I checked all the connectors and also watched a video where the disassemble the entire phone in order to see where I could have damaged or removed something. But as far as I can see, there is nothing loose or missing. I didn't remove the mainboard; I just took the device out of it's outside cover.
Hmm, i dont have idea whats wrong then.
I opened mine phone not once. Also replaced more 5 HD2 digitizers and lcds. All time dont had this probelm.
Are you sure you dont had static electric on your hands?
yes, I was protected against static electric.
maybe I'm gonna disassemble it totally and see if something else is loose.
Turning it on works, because the vibrator triggers once.
And I just realized that the power led does not work when I'm plugging the device in...strange
Hi all
So my S4 had an issue where it kept flashing the S View Cover UI (the black display with clock) even though I don't even own a S View Cover or use a magnetic case. I took it to Samsung Smart Care, they gave it a new mainboard, but the issue was still there.
I took it back to them yesterday, this time they replaced the entire LCD with the Frame, phone looks brand new and the S View issue seems to be gone.
So I'd just like to know out of curiosity, does the Magnet sensor come in the Screen assembly e.g. in the frame? If not, where is it located?
Just looking for some info that I Can't find doing searches.
My note 3 was thrown at a wall. The main impact was the upper right corner, near the front facing camera. The frame was bent and the front screen was shattered entirely. The screen did not even light up at all when turned on.
I've had the front screen / case replaced. The phone now looks as good as new but the following two things do not work:
- front camera (it works but its blurred. Repair guy said it was shattered)
- GPS (cannot get a lock at all, not even sure if its being detected or what)
I have a new front camera coming in the mail (less than $10), but where is the GPS? I know it's located around the impact area, but what are my options / what could it be? The repair shop said the board looks ok, but I only found out the GPS wasn't working when I was trying to use navigation on the way home.
Can I replace the GPS antenna? If so what is the part called as I cannot find it anywhere.
I am hoping that the repair shop didn't seat a ribbon cable or something but I know this is probably unlikely and that the GPS is broke. If this is the case, what can I do to fix it?
Thanks,
Hi,
I've recently changed the LCD panel on my Nexus 4, as well as the headphone jack (which includes the proximity sensor) - the screen was broken, and the headphone jack had very noisy output.
After putting it back together, I noticed that the proximity sensor wasn't working - during calls, it would constantly blank out the screen, and there was no way to unblank it (i.e. it seems to permanently think there's something there).
I took it apart again and noticed that the rubber gasket that fits behind the sensor is missing - it must have come off during the repair and gotten lost.
I tried putting some Blu-Tack behind it as a temporary fix, but no change. Now, I'm not so sure the new proximity sensor is working either.
Anyhow, my first question is, where can I buy a replacement rubber gasket? I've done a search online, and I can't seem to find it for sale anywhere?
Is it available as part of another spare part for the Nexus 4?
Cheers,
Victor
I had to replace the screen on my n4 too and fixing the proximity sensor was a pain in the ass. I had the rubber gasket but it was only working when the front panel was not attached as soon as i attached the front panel it stops working i.e. when in call the screen goes off but it doesn't come back on. So what the guy did was to scratch off the two holes on the top left from the inside of the panel. its looks a bit nasty but its working fine now. you might wana try to scratch off a bit neatly. like in a round shape.
I dont know if the gasket is the cause, but I know a case where this exact problem happens : its when u don't push the sensor well enough to fit in its place, cuz it should be near enough, or it'd blank the screen during calls. Try using a flat screw driver, and push the orange part where the sensors are well enough, that should do the work ( don't push haaard or I'll Damage it). I hope that'd help, cuz finding this gasket is hard. And this applies also for the guy who commented, cuz this is the case for him

According to this post:
http://forum.xda-developers.com/nexus-4/help/proximity-sensor-rubber-part-t2571396
the LG part number is MBL65457701
I managed to find an eBay seller selling it (original_parts_mobile_99):

I used a small piece of credit card, drilled two holes with t3 screwdriver. Worked like a charm!!!!
