Hi! So my Wizard (well, the T-Mobile MDA) had an issue where its USB port became completely detached, so I found the service manual and opened it up to fix it. When I got the back housing off to expose the relevant circuit board, a small metal part flew out, and I can't for the life of me figure out where it belongs. The pictures in the manual aren't high enough resolution for me to be able to tell where this tiny sliver of metal fits in. I've since done the soldering I needed to do and fixed the USB jack, and the phone seems to work fine... I've attached two pictures of the part in question, with the phone for scale on the first one.
Any ideas? If I'm not noticing any functional differences, is it reasonable to just not worry about it? Thanks!
That is the spring clip that holds the stylus in place. I mounts inside the cover over where the stylus goes.
Fantastic. Thanks!
Thanks a million from me too....had the exact same problem yesterday!
Stylist retaining spring
Thanks for the info - I too found this after disassembling my to check and clean the buttons. Although, now it isn't working - rats! I had hoped that finding where this belonged would solve that.

EDIT: DISREGARD THIS. GO TO POST #3 and #4
Hello guys,
this is my first post so if I'm posting in the wrong section please bear with me.
I recently bought a T5388++ HTC diamond 2 clone. Everything was fine except that I couldn't get a GPS fix. (In the Start -> Settings -> System -> GPS Settings [Satellite State] I only had *red* satellites)
I used the "aluminum foil in the back side" fix, which worked well and I could get a fix.
Being an uneasy person I open the back cover of the cell phone to take a look (beware the headphone cables).
Now here is the good part.
On the left side (near the sd card and where the stylus ends) is probably the GPS antenna.
In the inside, on the board's side, there are two metallic "pins" which (when the cover is closed) touch the back of the antenna. What I did was to add some foil on the back side of the antenna so the contact with the pins would be more tight.
This worked like a charm and the signal is very good. I can even get a decent fix (3-4 *blue* satellites) from inside the house.
Sorry for the lack of pics, if anyone tries it, post a couple pictures and I can show you what I did exactly.
EDIT: DISREGARD THIS. GO TO POST #3 and #4
Pics!!!!
Here are some pics.
First unscrew the four screws, one at each corner of the phone.
Then slice the phone with the help of small flat screwdriver or some other tool. (there are some appropriate notches for that purpose)
**Beware of falling parts**
In the forth and fifth pic you can see where I install the alu foil.
Now you can close the phone and enjoy your newly found GPS!
[I also tried some solder, but the results where almost the same]
Congrats.
However, I can assure you that is not the GPS antenna. Based on the antenna size and shape (its a small inverted F antenna, see the black sticker that is attached to in on top of the stylus case) I am assuming it is either the Bluetooth or WiFi antenna.
The GPS antenna is a bit higher, it is the small pink 'cube' thingy on top of the phone, connected by the micro coax connector.
I had reported before the micro coax is loose in some devices, and I suspect you 'accidentally' fitted it better while opening and closing the phone.
But congrats on your successful operation anyway, being able to open and close the phone and still have a working one is already good, and often, just doing that and ensuring all connectors are clean and properly fit solves a all sorts of problems.
Yeap you are right!
I have read you saying this about loose connectors, so when i first opened the phone I refitted the micro coax.
In my defense I tried to see if this was the antenna. I disconnected it and opened the GPS. Seeing many satellites on the screen (red ones) I concluded that this was not the GPS antenna. (I thought maybe WiFi since I've seen this type of connector on my laptop's wifi)
But having read your post now, I tried a new experiment and found out that the "red" satellites appear, due to the A-GPS (with neither "my" GPS and THE GPS antenna).
Damn...
So could someone change the title to "OLD GPS reception fix"
I had the same problem with GPS. I have risked and have changed orientation GPS of the antenna - GPS perfectly works. BUT now the speaker in which I hear the interlocutor doesn't work for me. At other person after the assembly has broken touch the panel. Therefore it is better not to recommend to open phone.

You changed the orientation of the antenna. In which way?
When I opened the phone to see if the connector is set right one cable to the speaker was dispatched (very bad soldering). I had to remove the old cable and solder another one because it was not only loose it was broken, too...grrrr...that's very bad.
But I was lucky and did't burned my phone
So, I also recommend to be VERY careful when opening the phone.
BTW: It is much simplier to open the T5388++ than my ASUS P535.

Can you please identify Wifi antenna? Look in attachment:
"C" is GPS antenna.
What is "A" "B" "D" ?
"D" - I see little piece of aluminum foil, but nothing else. Under this foil is place for stylus only and above foil is contact + Vibration Motor.
Somewhere I reed a tip not to hold the hand on the bottom of this phone during the phone call in order not to shield located there GSM antenna, so it means B is probably GSM. Are you sure C is BT and not GPS?
You're right. "C" is 100% GPS antenna. My mistake. (I've changed it now in original post.)
Well, my guess is B (at the bottom) is GSM, based on the fact it is larger (lower frequency) and seems to have two (one for the 850/900 MHz and one for 1800/1900Mhz), which leaves A and D for Blue and WiFi.
PS: Or GSM has two because it has 2 radio's? I wonder if they would share antenna or not, since it is a dual-sim dual standby, I guess the could share)
serak_hd2 WiFi probl.
If you have opened your phone already you can easily discover which one is wifi and BT. Just put a peace of paper on one contact (blocking connection), reassemble (screws are not necessary) and try connect to BT devise (compare to previous performance(distance)) if it is gone (or big performance difference), you blocked BT if not, it was WiFi. After you know which is Wifi, just try to ensure good mechanical contact from antenna till the board (bending contactors little higher or putting allufoil (aluminum can oxidize quickly, so it is not the best solution)). Try not to touch the board, some of the components can be sensible to static discharges. If you have not opened it yet, try to consider ones more the possibility to change it by your seller for new one.
problem with touch screen
t5388 + + touch screen does not work, but the image looks perfectly fine.
How to fix this?
thanks

I also had this problem, the connector was loose, now I have very good signal. No aluminium foil needed. Your post saved me!
My recommendation to other people trying to solve this problem: be VERY careful when you open your phone.
Prying the frame open wasn't such a problem although you should be careful not to force anything, it actually clicks open nicely when handled carefully. I ran into problems with the little bridge of the GPS, it broke of when I looked at it. Well actually I did help a little with a screwdriver but it broke on touch so to speak.
So there I was with a broken GPS and my sight isn't everything either so what to do. Well I found a solution. Have a seat. This is shocking.
I folded a peace of alu foil a few times and fitted it in the little space on the speaker just left from the gps and covered the broken bridge with it. I wont have to tell how difficult this is considering you have to avoid all contacts in this area. So if you try it it's your choice.
Result. A blasting fast GPS that indeed gives me never seen before fixes. This just must be my lucky day. Geocaches here I come. Time to put my external GPS aside again. Nothing beats a mad hatter.
So you kind of inadvertently upgraded the GPS antennae!
Thanks for posting, don't suppose you could post a picture?
Been checking this GPS thing myself.
I actually wonder how people manage to break that contact. You only have to bring it up a notch.
When checking the back cover you can see that there are 2 places that are contacts. i've checked with the multimeter and both are connected to each other.
Now there is one thing that is strange to me. The contact that is not the one touching the metal 'spring', well on the circuitboard there is this what looks like a piece of conducting foam that would make contact with the other one on the back. Measuring that foam it indeed conducts. It conducts to ground (measured between the coax connector and foam = 0 Ohms).
Now I actually dont know if it really touches the antenna but it would be odd to create a contact when it would not be touching.
So maybe there are 2 places that should make contact to the antenna.
Does anyone have an actual clue, or even better pictures, of the changes that were made on the models after October?
Hi to all,
sorry for my english but i gonna try to explain how to fix GPS in LG G5:
1. you need to unsoldering 2 mhf rf connectors like you see in pic1.
2.after that you need to solder 2 wireup cabels like you see in pic2.
3.in the end this is how it gonna look, like you see in pic3 and pic 4.
Good luck!
Where to solder the two cables on the other side?
Inviato dal mio LG-H850 utilizzando Tapatalk
No where, they just attached to the frame with duct tape.
Can you explain a bit more, what are pic 1 and pic 2 are are you removing whatever is there. It look like pogo pin not sure...
In pic1 you see mhf connectors\pogo pins as you call it on the board as they comes from the factory. in pic2 I unsoldered them, so this is how the board looking like after I removed them. I marked with the yellow dots where I solder the wireup (wireup is marked in red).
I understand now that you are using a thru hole RF connector and place a wire that act as an antenna, I wasn't able to locate where is the normal antenna and why is it not connecting right at the first place. it seem that the RF connector is not used normally so it is probably there only for factory test purpose from the ifixit teardown pictures.
https://d3nevzfk7ii3be.cloudfront.net/igi/KEVL1LUslTEBSoVO.huge
What kind of improvement did you get on the GPS, mine is working but not great so I am tempted to fix it but I am still not understanding what the fix does for now as I have to extrapolate that you are actually making an antenna with the wire. Lenght should matter quite a lot then, did you make a few test with various length to came up with the fix you documented.
There's another thread with a gps fix, but he's only putting more spring into some pins this fix may be better on the long run!
Thanks for the explanation
Before fix I barely get gps fix, I needed to wait about 5 min to get fix, after that the gps was not stable at all, it always get 5 satellites in max.
After fix I get gps fix after 10-15 sec, and I always get between 19-21 satellites, and gps works stable without any disconnections.
About the wire length, I didn't tried various lengths.
Getting yourself familiar with the insides always a good ideal. There's a good app in the play store called 'iFixit'. It's helped me with a lot of different devices opening up.

How bout does the iron need to be? What kind of solder should I use?

The iron temperature actually depend on the solder you use, you ideally need something that melt fairly low like 63/37 alloy 63/37 Sn-Pb used principally in electrical/electronic work. 63/37 is a eutectic alloy of these metals, which: has the lowest melting point (183 °C or 361 °F) Other eutetic alloy without lead may be availlable in your area. You also need the type with Rosin flux not acid or water washable.
You will also need a small tip at the end of the soldering iron and a good magnifier, but working with multilayer PC board with no experience can easily lead to catastrophic failure.
I would recommend you start with easier mods than this one if you are not familiar with soldering and general soldering on PCB, this is a fairly easy thing to do for someone familiar with this type of work as the hard work is to figure out what to do
Maybe find a local cellular repair shop and ask them if they can do it for you.
@slavush - thanks for the info here. Can I ask how you determined which connectors were related to GPS? Any documentation about the PCB or similar?
There are different people mentioning different pins all over the G5 for GPS. I have opened up mine 3 or 4 times now, each time finding success for a short period. So I failed to determine which were actually the ones to focus on.
In your opinion, instead of welding the cable, would it be possible to plug it into the connector hole?
I tried to put the cable in on the phone as in the picture without connecting it. But when the cable is inside the phone does not turn on.
My gps does not work. It does not even hook up to a satellite

How about now? Is this fix still working?
Also curious about. Any fix that really works?
I already fix my GPS without soldering.... But in order to fix it you should disassemble the G5 and look for 3 pins....
Sent from my LG-H860 using Tapatalk
I don't think the 3 pins mentioned are concerned with the gps. I tried myself lots of time to raise them up and the gps for a while worked, but, now i broke those 3 pins. No more volume...but gps works...extremely bad and slowly as before. If you look at the flex
you can see it is only related to the volume buttons. So...I don't have any idea.
About this soldering fix.....why shall I have to unsolder those two things?
the 3 pin worked for 6 month... and never worked again, 3 is crashed a bit now, also, i added aluminum foil to the 3 min, so volume up down still work.
I was going to try this fix mentioned here, untill i open the phone and found how Small the POGO pin is.
seems quite hard to remove as there is so many electronic around it.
i am going to just Plug in the cable and TAPE it in place and see if it can work this way..
Update:
Interesting enough, the phone refuse to turn on (with the 2 cable TAPED over the pogo pin. ) it just wont turn on.
Now, i removed the wire from lower pogo pin, with the upper remain. and the phone can turn on.
will go test the gps and see
@slavush, I see that you are from Israel. Any chance you're from Tel Aviv? I could use some help with this.
@scoobychau, did you get success in gps signal improve?
How did you it ?

Hello scoobychau,
My LG G5's 3rd pin is also crashed, broken, destroyed. Can you explain me more about how you fixed it with aluminium foil ? It's my girl friend's phone, and I am so sorry having broken its volume buttons' spins or/and GPS feature.
Thanks a lot for your answers.
Concerning the soldering, I am so bad that I can't imagine doingit myself...
Hello
I can't charge my LG G2 D802, so I ordered a charging flex cablefrom ebay.
After replaced, the phone charges well, but the screen is almost unresponsive.
And it's very interesting, because if I replace to the old one, everything is the same, almost unresponsive screen, not like before disassembly...
Any idea what to do?
Connectors and everything looks fine, but I can't believe touch screen stop working after disassembly.
Please help if You could...
Thank You!
You disassembled the phone? If you didn't put all the components back in place as it comes from factory and taped, then there could be grounding issues. There is a set of transistors next to the lcd connector and above the charging port, make sure it's touching the golden pad on bottom and is taped.
Or else it's a bad cable, bad grounding somehow, moisture issues etc etc.
I think You're right.
The set of transistors may not connecting well.
Can I use processor pasta to glue it back?
Or just some simple tape from above?
-----------------------------------------------------------
So I cleaned it with alcohol and the original glue getting stronger, so I put it back to the right place and put some tape on it.
But still the same.
Do I have to put tape on the cables above the battery?
How could I find where is the bad grounding?

No i don't recommend to put thermal paste therez if it conductive it can short nearby components and can also get messy, it is only for using on chips. I suggest you use double sided tape, but do it strategically so that it leaves a small portion open for the golden pad to make contact. And after that you put nonconductive tape on top of that. Make sure the metal part of the white cable nearby is not touching this area, or you can also put tape between them. I suggest to put tape on the lcd connector as well.
Whenever this problem arises, and if you have trouble to fix it, an easy way is to disconnect and reconnect the battery after a few seconds, should work ok.
You can also purchase a new one like this, look for your device model - https://m.ebay.com/itm/183023879505

Seems like the set of transistors well connected now and I put tapes on it and on the screen connector as well.
And I reconnected the battery too, but nothing happened.
It's the same as before.
And if I replace the charging port flex cable to the old one, it's the same too, but before disassembly it works, but the problem was I cannot charge the phone.
Any other idea what should I do to fix it?
I cannot choose D802 on the link You gave me...
Anyway I think this one and the old one is fine if it's about the touch screen, have to be something another...
