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,

Antena it's in up-left when you watch on phone.
I am almost sure at the left side directly under the volume button .

It won't be in the upper portion of the phone, as this increases the strength of the radation the head is exposed to. I believe there is a law prohibiting it from being too near to the skull. Which is why all antennas in modern phones are internal and not placed by the speaker at the top of the phone.
Although this seems to not apply to GPS, Bluetooth and Wi-Fi, which is what those wires by the speaker at the top of the phone are.
Class 1 Bluetooth devices can cause exposure to radiation similar to that emitted by a cell phone if they are operated in the immediate vicinity of
the body. Bluetooth devices are designed to limit the radiation power exactly to that actually required. When the
receiving device indicates that it is a few meters away, the transmitter immediately modifies its signal strength to
suit the exact range, which reduces the total emitted radiation and signal interference (IT'IS 2005).
A study commissioned by the Swiss Federal Office of Public Health (FOPH) measured SAR for several Bluetooth
devices, including two different class 3 hands-free cell phone headsets. The headsets tested had SAR values of
0.001 and 0.003 W/kg, which is 34 and 12 times lower than the SAR of the lowest-emission cell phone currently
available (Swiss Federal Office of Public Health 2009a).

The cell antenna is the strip on the bottom below the battery door,the wifi antenna is at the top right (if looking at it with the screen up),and the gps antenna is at the top left. There is a white cable that is supposed to run from the gps antenna to the bottom side of the main board,and a black shorter antenna cable that is for wifi that plugs into the top part of the board. I have a pretty strong feeling that the person that fixed your phones (whether that was you or someone else) probably didn't plug that cable in the right way.
<EDIT> By the way,if either of you want one that works the right way/for parts,I have one for sale that the volume buttons don't work and the lcd is cracked,but everything works other than the volume buttons.

Anyone ever have any antenna issues without taking apart the phone? my phone just developed issues with dropping wifi unless im close to the router, im guessing an antenna cable is loose. and for those who have fixed the antenna issue, how hard was it?
according to the HD2 manual, the antenna is the bottom 1/5 of the phone

The WiFi antenna is located at the right of the camera watching the camera in the back panel. If you watch this video, http://pockethacks.com/category/service-manuals/, you will see that the Bluetooth/Wireless atennas are located together and connected to the main board with a coaxial cable.

What this guy said +1
I find myself in a similar situation to nedko76. I had to take my phone apart but just the case away from the screen circuit boards etc because the plastic led shield had come lose and was touching the vibration device causing a strange noise.
So i managed to get the phone apart (which was not as easy as shown in the video) i didn't touch the screen part at all, put it back together again and switched it on. To my relief it switched on, all looked good, the noise had gone from the vibrator however the only thing that is not working is the wifi.
I'm hoping someone has resolved a similar issue without the need to reopen the phone again as i can't help but think i will do this and see nothing wrong. Which would either mean i've somehow damaged the wifi circuit board or something else.
I use wifi alot and will miss it loads if i can't find a way to fix it.
As already mentioned, WiFi antenna seems to be feeded by a tiny cable, it is probably using some tiny coaxial connectors, those are usually relatively easy to accidentally disconnect. I would start from looking at those and making sure they are "wedged in" properly.
I have taken the phone back apart and checked all wires are pushed in and everything is connected from what i can see. But still nothing.
Wifi switches on but just stays at scanning. Now does that mean that the wifi is working but the antenna is the issue.
I'm just wondering if its a software issue somehow. As i never touched any part of the board, or antenna etc whilst it was apart and like i've said i couldnt see anything out of place or loose.
Dude,
There are 2 brass clips on the top right of the motherboard which attach to the rear case antenna. Make sure these brass clips are correctly functioning and working. There are 2 for the gps at top left big ones from memory then there are 2 at bottom for radio antenna and two at top right for wifi.
Make sure these are all ok...
If you can post a detailed photo(s) I can give you more assistance. Zoom in the motherboard and the clips if you do provide pictures.
Good luck
Yeah i saw these when i took the case back off yesterday, i looked at all them to see if there were any differances, any broken off etc but they all looked fine. I did lift the ones for the wifi and bluetooth just a little bit to make sure when the case went back on they would be in contact. But still no luck.
I find it difficult to believe that just taking the case off pushing a little bit flashlight plastic back into place would really stop the wifi/bluetooth from working.
I'll have to keep searching the web to see if anyone has resolved the same issue and what it actually is. It would be interesting to see if people take their cases off then just put them back on again if they have the same issue or whether somehow i've messed something up.
Dude, show me a pic of motherboard to see if all your connections coaxial are ok.
Otherwise, your hardware maybe fubar. I have opened mine several times and no probs.
Right I took my phone apart again this morning to double check everything. I noticed the cable attached at the bottom as mentioned in previous post. It lifted off a bit too easily, so I positioned it correctly and pushed it back down, my WiFi now works. So that was my issue.
So my advice would be if both your Bluetooth and WiFi do not work, it is more than likely the cable is lose. (more likely if your phone has been a part obviously)
Thanks for everyone's help and advice on here. no fubar hardware here thankfully

I'm also experiencing this after changing a smashed screen... The accident it self did hardly cause this since I used the phone with full performance for about a week between dropping it on the ground and draging my sorry ass to the retailer. Since I don't intend to open this stuff up I guess I'll have to go back there. I will refer to this site if they try to indicate that their sloppy disassembling isn't the reason... Please, feel free to boost me with more cases like this...
I have replaced the screen myself and have the same problem with Wi-Fi only.
I dont know why Wi-Fi run only without the battery cover.
I' m trying to torque chassis for looking if it is a mechanical issue but it seem not.
I've tried also to connect the two little contact they are at the same level with the bottom of the battery looking the phone from its back without the cover.
I've not found yet any relevancy with the presence or not of the back cover related with Wi-Fi transmission.
I remember that when the phone was disassembled, I have slighty lifted with my finger the bigger one of the two lamellar contact of Wi-Fi antenna; anyone know if this could be the cause? Must to touch these contacts chassis or not ?
nothing else ?
Hi,
I strugled a few month to get GPS on my I9000 working for car navigation. I tried different radio versions, GPS settings and hardware tweaks (bending the antenna contact), but GPS was usable for max. 10min and then there was no GPS fix again.
The solution in MY CASE was:
- remove the Galaxy S lether flip case!!! I have an flip case made by Noreve and the entire back side is some metal mesh covered by lether. So when I use an normal silicon case, I have an quick and stable GPS fix even in a car with heatable front panel .
My software configuration is the following:
- Android 2.3.3 (from samfirmware flashed by odin),
- Baseband version I9000XXJVO
- Buildno. XWJVI
GPS settings (defined by GPS testmode *#3214789650#)
- Test Mode: S/W Test
- Operation Mode: MSBASED
- Start Mode: Hot start
- GPS Plus: ON
- GPS Logging: OFF
Kind regards
hqqh
Jajajaj, this must be one of the most funny posts I've read here. "Hardware fix" you call it.
Next:
Low screen brightness solved: Remove your sunglases
Low speaker volume solved: Do not carry the phone inside a sealed box
Low phone signal solved: Do not carry the phone inside a metal box
Compass orientation solved: Do not hold the phone near a magnet
GPS not getting a fix: Get outside
Pictures taken with the camera all black: Do not put the finger over the lens
Night pictures too dark: Turn on the lights, the SGS has no flash LEDs
-----------------------------------------------
Now, following in this issue, I've noticed that when using a high capacity battery (the ones that are thicker than the official one), the GPS does not work so well. So this is a similar issue with 3rd party hardware interfering with the SGS antennas.

haha this is really fun thx
In praise of all the people that keep it light n fun

BUT ... the SGS GPS is not so bad anymore with the later firmware. We are looking too much maybe.
Iphone 4's and my camera with GPS have about the same issues getting a lock.
Software can obviously still improve: reported accurace behaves funny, there is a stick-to-current-position effect, VDOP is often lower than HDOP which is suspicious, etc. But in all it seems not broken anymore.
Though the chipset is Broadcom... and they always seem to have issues with driver quality, whether it is server network cards (the German original they bought over had decent drivers, at least for Linux) or GPS chips...

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!!!!
Yesterday, my note 3 made a fall from a slip in my hand, and now, there's a little crack at the top left on the screen. The screen is not turning on, and I think it is no more registering touches.
Amazingly enough, the glass protector does not have any scratch, but I can clearly see small crack in the LCD behind.
The sound is working fine.
I have already opened the case and have unplugged and re-plugged the connections, still no change.
My question: I want to confirm whether the screen and digitizer have been damaged. Any ideas/ advise on how to confirm this ?
Basically, I want to go ahead and buy a screen and digitizer replacement and perform the change, and I didnt want to invest on something which might not be needed.
Please provide your help and views guys.
Thanking you all.
Screen fixed. Camera issue
Just to post an update.
I had ordered a screen and digitizer for my N9005. Yesterday, with a rather fast shipping, it got delivered.
I carried out the swap, ie, removed all sensors, camera, vibrator, mainboard from my existing and transfer to the new screen/digitizer.
All went okay, screen, touch, all sensors, front cam.
Just that my rear (main) camera shows some artifacts on the image - on the camera screen and the photo taken. See attached.
It seems like it is showing some piece of glass fractured or scattered. Any help on how to proceed from here ?
I was trying to remove the middle plate (where the outer lens is found), so see whether this lens is broken, but as per my tests, I see that the phone refuses to power on once this plate is removed.
Info: The photo attached is when I pointed my camera to shoot over a white wall.
Any help is welcome, please.

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?
