It's a noise issue with the gps antenna and other h/w on the board (mainly lcd cable.) It can be fixed by insulating the board from electrical shorts (scotch tape in my case) and shielding the board from the antenna with aluminum foil. Not for the faint of heart, obviously you can ruin your phone if not done correctly. If your wondering how much of a difference it'll make lets say my GPS works in my basement, in walmart, even in a multistory business office. I have yet to find a spot where it won't work. Most times it locks the instant it's opened, indoors you might have to wait maybe 10-30 secs.
If you think shielding the whole phone will help the other antennas, it won't I tried. You only have to do the corner that the GPS antenna is located and of course ground it. The GPS antenna is labeled with the letter G on the case of the phone. It's inbetween the camera, battery, and power button. Face down camera up, it's located upper left portion of the phone. Each antenna looks like a black label, please don't peal them off. Phone must be disassembled to perform this mod. I will not tell you how to take it apart (google it) nor be responsible if you break it. If you don't understand the concept of shielding or are unclear how to do this mod you shouldn't be doing it. You should be asking a friend that understands electronics better (aka major electronics geek) to do this for you.
Sorry I don't have pictures at this time.

Only the area where the GPS antenna resides needs to be shielded which on the Nexus S 4G happens to be circled in red.
Don't forget to protect the board from electrical shorts with scotch tape or the like.
Please don't put tape or aluminum foil over the spring terminals as they provide contact to the antennas on the back of the case.
The shield must be grounded for it to work, I used the metal casing inside the phone.
You can see where it comes close to the edge of the phone, it happens to be metal there and its grounded
In for pics. Also, which model phone.
crespo4g aka SPH-D720 aka Nexus S 4G
But TBH this solution should work on any phone that has bad GPS reception due to bad design and/or h/w interference.

Sounds similar to the other fix which didn't work for me. Do you have pics of your mod?

Yea I just put one up. I've tried many things myself but this has made my phone's GPS f***in fantastic and thought I'd share it with the rest of the world to enjoy. I first tried modifying my antenna with a wire after trying a bunch of useless s/w mods but still wouldn't work once reassembled and then it became obvious what must be done.
Dude, that fix looks so hood rich. I love it.

Hi all,
I have the following isue: after I gave my qtek 8310 to my sister, it seems the back cover is somewhat broken or malformed because I cannot close it. My sister told me she hasn't done anything but it is possible she forced the back cover in some way. When I try closing the back cover, it doesn't fit well to the phone's body and doesn't make a click sound as usual. As a result it cannot be attached to the phone's body and fully closed. This happens even when there is no battery installed.
Visually I cannot see anything broken and the plastic seems OK. There are no obvious malformations.
Has anyone had such similar issue? Maybe I have to buy a new cover, however I haven't found any website to purchase spare parts for the qtek 8310.
Any help would be appreciated. Thanks in advance!
yo! post here snapshots of the "unshut" back cover so that we may see how can we help ya
10x for the reply.
I will make the shots tonight with my camera and post the links.
even if u dont post, i suspect that either of these slots of ur cell phone are blocked:

Same problem
Hi, I have got the same problem. I have found, the back cover get broken because the battery was old and become "bigger" (got inflated by gas produced in battery by chemical reaction). I have changed the battery, but have not found way to repair the back cover. Maybe just use some hot temperature...
Got the same problem here: seems like the battery has curved (!) it has got a slight bump...
the battery doesn't fit properly anymore - same with the back-cover!
Also my battery drain is quite high... well, it's an 3 year old tornado
on the grey cover, inside, theres the 2 clips, one of them was bent downwards touching the surface, and thus i couldnt slide the cover on without it lopsided or loose. I just lifted the clip a little and fixed it. Be careful its like cheap plastic, felt like it would break easily

Hi again, it seems my problem was exactly the same like lmf's. I just lifted the clips and now the cover fits and slides correctly.
Thank you very much 'dark_prince' for the picture and advice and 'lmf' for further tips. Now I have a happy working tornado with a back cover If we ever meet in real life I owe you many, many beers
Lol that strange maybe you cellphone is pregnet by a noki or a sonyerricson
My vibration motor in the Nexus s broke. Now I want to replace it. I'm planning to order this motor: http://www.tvc-mall.com/details/Replacement-Vib-Vibration-Motor-for-All-Samsung-Models-SAMO-SAM/
I opened up my Nexus to a degree where I could see the motor, but I couldn't see how the wires are connected. Do I have to braze the wires or can I just plug them in or how does it work?
Thanks!
Are you positive it is broken? Mine stopped working on me a few times before. I would tap the phone firmly, powered it off and tap again and reboot. Problem solved. Just a fyi

Yes I'm sure it is broken.
Thanks tylerwatt12, for that picture.
Crap I don't have the equipment to solder.

A 15W soldering iron should run you around $10 US.
I highly recommend soldering wires on random scrap if this is your first experience at soldering or you're gonna end up with a mess.
Edit: Or you can cut the wires, strip the ends, twist them together and solder (then cover them with heatshrink/electrical tape).
Should be easier for a beginner to do this than solder on tiny pads and remove epoxy from a PCB.

Thanks, pretty stupid, I didn't think of that. I might not even have to solder at all if i twist them together tightly and then bind them with tape.
riichii, have you managed to do it? I'm positive my vibration motor is broken as well, but I cannot find an exact replacement online. A friend of mine had a broken samsung j700 lying around so I salvaged the motor from it and soldered it in my nexus s, but it didn't work (you could hear the motor rattling, but it wasn't vibrating enough, it was less than my broken original motor). I was wondering if the part you linked was working or not. Thanks
Just dropped my phone on the edge of a glass table from a height if about 1.5 ft. The backing separated a bit (2mm, I just popped it back in) and there now a wee groove right by the headphone connector. Other than cosmetic, there *seems* to be no internal damage. Everything works fine as far as I am able to tell, including using headphones and I hear nothing rattling inside when I shake it. There are these barely audible squeal/ tiny beeps in that area which I can only hear when I put my ear right up to it, but that may be normal?
My question to you good people is, should I be worried that something on the inside may have become loose and cause problems down the lane? Or all is well as long it works okay? How can I check to be sure?

You should be fine, if there doesn't seem to be any internal damage, then you probably have nothing to worry about. Water damage tends to be less predictable, not drops.
As for that dent, maybe you can get a replacement housing.

Thanks, that kinda what I figured too, but now I'm just paranoid that something broke internally or damaged just enough to work itself loose in time. But that hint you gave about drop damage predictability makes sense.
I wish I could make sure.
Any ideas about the cost for LG repair service? I called them earlier and they were super unhelpful.
I should probably just look up a youtube tutorial on how to open the phone and peek inside.
Ok, yeah I should be fine After watching a guy disassemble his phone on youtube, there is nothing in that particular area other than the headphone jack. Looks like the plastic cover and the jack itself absorbed most if not all of the shock.

If you ever experience issues with it, the headphone jack on a nexus 5 is a super easy part to replace, as it's not soldered anywhere. Just clips as I heard from iFixit.
Three weeks with the Galaxy s4 7500mah battery and I almost felt like it was a wrong decision purchasing this product despite the days of battery it offered; courtesy of my phone losing signal every 50secs.
After a lot of test and failure including wrapping the battery with aluminium foil lol, I finally found a solution. What option did I have? at least it solved the problem that gave me headache.
The problem with Phones rocking Zero lemon accessories loosing signal lies mainly in the TPU CASE.
If you take the case off with only the battery left, everything works just fine. But bring back the TPU CASE and you are back to stone age.
Straight to the point; I overcame this issue by
1. Removed the TPU CASE and battery to expose the back of the phone
2. Located the phones antenna. Which lies in pair to the right and left of flash light.
3. Measured the distance of the antenna from the flash light to the end of the antenna which is about 2cm from the flash light to the end of the antenna on both sides of the flash light.

4. I now transferred the measurement using a ruler and a pen to the back of the TPU case.
5. Starting from the hole provided for the flash light,With a RAZOR I cut a rectangular shape out of the case.
6. With the flashlight hole as the reference point and center, I cut a tangent 2m above and below the flashlight hole to it right and left respectively to expose the two antennas.
7. A vertical height of 0.5cm for the rectangle and 4cm for it horizontal length. Giving 2cm to each sides of the flash light hole.
This pretty much solved my signal lose. I Hope it solves yours for you too.
Can you post pics of the cut on the actual case? Thanks

Sorry for the poor image quality on the second photo. Used Webcam as the phone had to go into the case.
@NDELEON thanks for the pics
so tpu cases in general are teh suck for reception?
I never had any loss of signal with mine? :s and I used the exact same 7500 zero lemon tpu case. Strange!
Hi guys,
Well, I'm that idiot who broke his GPS/WiFi antenna.
With the new launch of the OP3, and my utterly empty wallet, I thought it was about time to replace the battery on my OPO since it was lasting about half a day now. Ordered a battery online, broke apart my phone, replaced the battery, bish bash bosh didn't take long at all.
Little did I know, when taking off the board protector it looks like I managed to snap off this little bugger (red circle bottom right):

Since I didn't realise I'd done it, I never found the little bit I broke off and it's forever into the void (you know, the one where socks and case screws go).
Since I'm a very broke university student and I really wanted my OPO to last me another 2-3 years without me getting lost (I have a really horrible sense of direction), does anybody have any knowledge about this board that would give me a hand modding it to have the antenna work again?
If only it were just WiFi, or bluetooth, or NFC, or something else I never use, but it had to be GPS, the thing I use constantly!
If anybody could help me I'd appreciate it significantly, and if you're nearby I'll buy you a pint. Or a pizza. Or something.
Thanks guys.
PS My battery lasts two days now, so I've got that going for me, which is nice.

I think someone else did the same thing and hacked theirs with a piece of foil or something. It's just a contact. Maybe you got a bud who can do some nice surface-solder.

Possibly, yeah. I might fiddle around with it. It looks like the tiny antenna slot on the left of the red circle is the part of the same antenna system, do you reckon if I plugged an antenna cable into that it would be a workaround? I don't suppose you happen to know what that type of connector is called?
Cheers.

Got no idea on the answers to any of those questions. Google for ideas? Good luck.
