are these for external antenna?

When you open up the back cover, you see these 3 ports (W1, W2, R1)... are they for external antennas? is so is it possible to buy a antenna to boost 4G reception inside buildings?

looks like they are for antennas but I'm not sure anyone has figured out how to use them. I would love to know, my biggest complained about this phone is its horrible wifi reception.

actually nevermind maybe not: http://forum.xda-developers.com/showpost.php?p=8363821&postcount=53

Was curious about this as well.
Between those two threads it seems like some people think they're antenna connectors, others think they're for QA testing. They look just like the antenna connectors on a laptop wifi card, but that's just looks.

Somebody on the Nexus S 4G forum tried soldering a paperclip into his, to boost signal, and it ended bricked the radio. Apparently the radios are extremely sensitive to the impedance of the antenna and will easily burn out if it's lengthened.

I'd love to see him explain that to Sprint if he returned it, lol.

I used to work for Agilent/HP and those are called MMCX (micro mini connectors) used for high frequency signals (I'm talking high high as in microwave technology) - so yes you are correct they are very sensitive but I think what caused the brick of the radio is that the paperclip touched the conductive pin to the ground (the area around the pin). I wouldn't know what these connectors do unless we get a schematic of the PCBoard but I definitely wouldn't experiment around LOL

GPU fault after falling

Hello guys. I'm currently trying to fix a friends HOX that fell and now the screen doesn't always display image although we can see it always lighting up (it turns on but stays black) .
If I press hardly the HOX's area in red while turning it ON, it works fine. I'm assuming this could be some broken welding points but would like your opinion.

I'm thinking of heating the area with a heat gun, but I'm afraid I'll kill the rest of the phone... what do you think?
Also, after disassembling the phone, the vibration stopped working and I've checked every flat cable and every connector I could find...no ideas to fix this one since it was working before I cracked the phone open.
Any comments are greatly appreciated.
Tks

Possibly a chip has become partly detached from the solder ball grid array due to the shock of the fall. You will not be able to repair this by heating, even if you could reach the melting point of the solder.
The manufacturer would repair by replacing the circuit board and the existing one would be considered unserviceable.

So in resume, my friend has a HOX for spare parts... damn...

Couldn't you pack the inside of the housing at the point where you need to apply pressure? Using a piece of card or something. Hardly ideal but would make it functional again

That has been my first attempt, and it's better but still, not enough.
I'm going to disassemble it for the tenth time in a final effort...
tks for the tip though!

So, I've just realized the back metal plate comes out nicely and I think I've found the problem for the GPU issue... that small component on the red area has a broken piece lol (WTF!)
I have applied pressure directly on top of it and I think it will be usable like this, but it now needs a bit of daily use to check if I'm right or wrong.
Can anyone identify what component type is that?
Also, unfortunately (and I don't have a clue how this has happened), the vibration stopped working after opening the phone on the first time, any one has any ideas of what to look for? I don't see any flex cable cut or any other damaged parts...
Tks guys.

Problem solved, some back pressure on the broken piece and the hox is good to go.
The only thing still not working is the vibration...

Third party headphones issues

Hi, has any of you tried using different headphones than the one supplied by LG? I've recently bought a brand new AKG headphones and after a couple weeks it looked like the connection got lost. At first I thought it was a problem with the headphones wire (I always break them) and asked for a replacement. But I just received the new ones and it happens the same! It looks like the 3,5mm jack gets a little loose when you plug it and as soon as you move it slightly it gets disconnected and connected again.
I've been looking at the 3,5mm jack of the LG supplied headphones and the other ones I have at home and they all have 2 "stripes" but LG ones, that have 3, can it be a special jack port or something what is causing this, is just my phone faulty or all LG G3 came up like that? Thanks.

This is a very known problem. Search on the forum for aux.

Thx but it's not the same issue, in these posts the headphones worked fine and it was the aux cable what was not recognized. Here it's the headphones what get disconnected and connected again as you turn or move the jack.

I had that problem but only a few times and I guess its solved somehow. It just disconnected as soon as I moved the cable. I mainly linked those threads because there is a known problem with this phone aux. :/ I'm not sure how to actually solve your problem sadly. I'm sure you will get a replacement if you contact LG.

I sent them an email and they called me and told me to do a factory reset (??) and if it doesn't solve itself miraculously the talk to the retailer and they will have a look. I am so tired of this phone, every week I have a new problem...

charging board flex fix

if you're looking for charging port fix, here is a small tip i hope could help you..
you can read all the thread or just jump to bottom line
my charging port stopped working after about 3 months of usage.
this was very frustrating, and didn't happen at once. at first i had to put the charging cable in certain direction, and later on i had to put some leverage on that direction, until eventually i couldn't charge at all.
it is known that this phone is one of the hardest to open, and once you put it on the "surgical table" it's hard to finish the job without "scars" , so i do understand those of you who chooses repair stores over fixing adventures. on the other hand, at least in my country, HTC repair cost so much that you ought to think about other options.
So then my tip is for those of you who have the willing and repair equipment.
You'd probably look for replacement charging board, which indeed are very cheap, and then just check out one of the many tear-down youtube videos explaining how to open the phone and replace the port.
i chose to fix the exist port instead.
to be honest, i also bought replacement. but not only it got damaged, i've found out after opening the phone that there are the two different boards for 32G/16G versions. so instead of buying another part, and waiting another month or so until arrival, i figured i can try and check out what went wrong with the current one.
i did use lab microscope to find out the problem, but there weren't many suspects to begin with.
turns out for 3 out of the 5 micro USB pins (the middle 3) - the connection to the board got broken.

so i just used friend help and soldered the 5, and voilà, phone charging again..
note that -
1. the pins were barely soldered to the board. very little amount of tin
2. I've checked my USB cables and it does look like the metal connector length differ in sizes from one to another. even if not by much, it's clearly visible. so it's very likely that inserting a cable with long connector time after time just broke the connection.
bottom line,
if your charging port malfunctions, and you happen to have soldering equipment, or a friend who does, just carefully solder/strengthen exist soldering of the 5 USB pins to the charging board.
i guess you can even take the board and ask for any electronic repair shop just to solder those. will cost much less than expert store repair

HTC One M9 Wifi and Bluetooth not working

So my sd slot was messed up so I took it to get repaired, the guy fixed it but now wifi and bluetooth don't work properly. It only works when I'm extremely close to the router/bluetooth device and even an inch or two away and it disconnects. Is there any way I can fix this myself, or anywhere I can take it to to get fixed? I've tried but the guy I took it to had no idea how to fix it. I read knocking near the rear camera fixed it for some people, but I've tried that and it doesn't seem to work, and since I'm assuming the guy physically broke it somehow I doubt it's a software issue. Thanks.

Did he connect everything properly?. The WiFi and Bluetooth, I believe, are one in the same chip, or at least on the same board.
It could be a case of replacing the board but if it works close to the router then I'd say that maybe there's a problem with the antenna, if there is one. If there isn't I'd blame the cable supplying the power to that board..
The m9 is notoriously difficult to work on and it is VERY likely the repair was accidentally botched. The new problem is asking someone else to investigate and repair it properly. Don't tell the new guy it was buggered by someone else or he probably won't touch it.

I fixed it myself! I opened up the phone as a last resort basically to see if even my noob eye could detect anything, and I think I got what happened. There were two cables that were disconnected and I simply plugged it in and it worked. Thanks man.

Well played!. Glad you had the courage and got it fixed!

How do they look exactly when you plug then?... please help
