At first it worked fine but after 1 month it starts losing signal. I downloaded GPS fixes but no luck, anyone has same problems? I have a lenovo k3 note but that works fine even it is even cheaper. I look into specs, seems like stylo only eqipped with AGPS since most high end devices offer both GLONASS and AGPS.

Same here dont really know what's going on
Other than that, I love this phone,great price and overall performance. Still I gonna dump it soon as I need GPS everyday.
Same experience here. Even the digital compass just jiggles all over unable to lock GPS or direction.. Going to try a factory reset because it used to work fine before but today it's just failing to do anything at all... But seeing others with this phone with same or similar issues does not bode well even with a reset. It seems the phone can find some GLONASS locks in the attached images "triangles" but I think this may be in error in GPS Test.
Not happy to see so many people suffer from same thing but I am glad that I am not the only one. lol
It's the antenna.
I had problems like this as well. One day, I got mad enough to smack the back of the phone against my dashboard... and lo and behold, it started working again!
As it turns out, the NFC antenna is also the GPS antenna. There are a couple of pins on the phone that touch a pair of pads on the antenna, and if they don't make good contact, the GPS won't get a good signal.
I've found that removing the back and replacing it (being sure to snap it firmly in place) will usually fix the problem. I tried (not too hard) to pry up the little tab with the pads and stick some paper under it to force it firmly against the pins, but I'm thinking that the tab (and the rest of the antenna) might be glued in place.

seems like it is the solution! Hopefully can last........
So the factory rest worked on taming my digital compass and gps is now locking on but clearly the antenna on this phone is less then stellar because my old HTC Vivid seemed to have better gps reception (even with it metal backplate cover) as the snr ratio is worse here than my old phone. Its also much slower to lock on and more sensitive to your hand cupping the phone or how your holding it. I dont rely on gps much so at least its usable to a fault.. Everything else this phone provides is spot on.
The paper trick worked for me to just peel up the little contacts on the back piece and put a piece of paper behind it

I used toilet paper
fixed by replacing back plate
I was having the same problem with my TMobile LG G. I tried putting some paper underneath the antenna contacts, no luck. I ended up buying a used back plate off eBay for $9.
Completely fixed it. In my case, I think the original antenna was just faulty. I'd have sent it in for a warranty replacement if I hadn't, um, dropped the phone within a week of getting it and shattering the screen so I'd already had to get that fixed by an aftermarket repair place.
GPS lock fix
I tried a new back, and the paper under the contact trick, they didnt work. BUT I did read that taking the back off and tightening the screws that hold it together, will get the gps lock back. I pulled the back off and I did have several loose screws. After correcting, I rebooted the phone and gps is now operating perfectly!
I took off the back and made all the screws tight. It works fine now. Hopefully this helps others.

I'm guessing others have suffered from annoying, unresponsive joystick problems as much as I have. I read elsewhere online about using a drop of WD-40 lubricant on the joystick to solve the problem. I just wanted to let others here know that I tried this, and while at first it seemed like it didn't help or perhaps even made the problem worse, I've noticed that now my joystick responds *perfectly* - perhaps even better than when I first got it (I bought mine used).
I used these instructions to disassemble my SDA. I used the T6 Torx screwdriver included in this kit found at Dealextreme.com for US$2.65 with free international shipping.
Remove the plastic top from the joystick mechanism and let one drop of WD-40 soak into it. Move the joystick around (as if navigating on your phone) for about a minute to spread the WD-40 around.
Again, my experience was that at first it seemed to make it worse, but after the first day it got better and better. It's now gone one month without any problems.
Update: 8 months later and my joystick is still working perfectly, without any additional lubrication. I definitely recommend this process, though as usual with anything like this, attempt it at your own risk.
Hi,
KONTAKT working too
I didn't even take my spv c600 apart.
Just took the battery out.
Sprayed WD40 around the joystick and wiggled it about for a couple of mins ...
Then left it to dry.
Result = Perfect Joystick
Hey, my left softkey is not so responsive.
What could be the remedy? Mind showing the contacts between the keypad and the circuit board?
Thanks for the tip! I was hoping I wasn't going to have to take my phone apart though.
Cool, thank you! I had the same problem, and already bought and installed another keyboard - and got the joystick problem back after few months. Now I just sprayed WD40 around the joystick, wiggled it for a while, and it works like new! ) THANKS!
Just a warning: if you do this without disassembling the phone be very careful to only do ONE or TWO drops and sparingly. Although I thought I only did a couple, I now have a nice discolored "blob" going up through my lcd, not that it doesnt personalize it a bit, but not quite what I was going for
I just used to take a drop of alcohol on a little piece of paper tissue, with a toothpick carefully cleaning the base of the joystick around. This has always helped for 2-3 months.
Well, I always used deodorant spray when my joystick was not responsive (with phone closed, tilt the joystick both up & down and then spray, just a bit - no need to disassemble the phone). No problem, no stress.
I cleaned my joy in the same way. (disassembling cover + WD-40)
This is perfect way. I did that a 2-3 month ago and joy is still working perfectly.
I made the same with my old Motorola's and their joyisticks are working perfectly for about year now
Ps. WD-40 need some time to start working. Next day after cleaning everything should work very nice
Ps2. I don't recommend spraying WD-40 on non uncovered joystick. The best (and the safest) way is to spray only joy. I had to change microphone in my moto becouse of that ;P
thanks for sharing this. ill be doing it tonight!
white lithium grease in the spray can also works really well. Just take one small drop on a toothpick and pull joystick down and drop it in there.Its an easy alternative to having to take the phone apart. I did this last October and it still works great.
funny.. just seconds before i found this topic.. i put 2 drops of contactspray in the joystick. for so far it doesn't helps much..
so i am not the only one with these problems
sticky?
Mods: I'd like to suggest this thread be made a sticky.
WD-40 need some time to start working. Next day after cleaning everything should work very nice ！
I dropped my phone on concrete floor from about 4 ft high and it bounce up and bounce. luckily it is still working with some problem with power switch and few loose casing (I glued it with super glue).
To fix the unresponsive joystick I tried to open following the instructions but the screw near the power switch is not able to remove, seems something broken inside after that drop, and I could not completely open it. So, tried to put few drops of spirit on the joystick but I actually pour some. After that I thought joystick is responsive more but later it remains same. Yesterday only I found out my keypad backlight is not glowing in the dark. I don't know when the problem started, after that drop, after that spirit, or after some setting change (I flashed Kamadaze's Pro RC7).
Sorry for long story.. but someone help me .. my joystick & key backlight.
Thanks in advance.
I will try doing with some organic solvent, but first I will have to wait for my joystick to malfunction (I always use nineway keypad to keep my joystick safe though )
What is the exact name and company of WD-40. Can any one tell me its composition coz i have many chemical lab retailers around in my neighbouring city

I would have thought a generic "maintenance spray" would do the trick.
Anyone notice that the back cover of the Nexus S has two little gold contacts and some sort of grounding/antenna plane just like the Captivate?
http://cdn.slashgear.com/wp-content/uploads/2010/12/NEXUS-S-Hands-on-09-SlashGear-580x359.jpg
And
http://pocketnow.com/html/portal/news/0000011184/backopen.jpg
Perhaps it's only a ground plane or something, but there is a striking resemblance. We already know our Captivates have a little something special (in the back cover mechanism and inclusion of an Audience voice processing chip) that none of the other Galaxy S variants carry. Just speculation, but maybe there's a NFC radio hiding somewhere in our devices and that "ground plane" is actually the antenna. Perhaps if someone can discover what exactly the NFC antenna looks like (if it's internal, or integrated into the back cover of the Nexus S) we could make a better guess.
Unless someone else has a more reasonable explanation?
well thats an interseting theory. kind of a stretch though, any number of things it can be. i mean because the nexus has two contact points and has nfc doesnt mean that the points are related to nfc. i think that the cappy not having nfc is evidence that the backplate is not used for nfc. but we may have un used hardware, if i knew more about antennas and nfc and things i guess i could draw a better conclusion.
i can tell you that the round point on the cappy goes to ground through a plating on the back of the plastic over. i made no attempt to trace the contact that is on the board. if someone with knowledge in the area of antennas could coment that would be great but it's probably nothing.
I've noticed this too.
If you tilt the back door at the right angle to the light, you can see a vague pattern (at least on mine) which looks like an RFID antenna in the recessed square on the back. Maybe it's something? RF is not my specialty, but it looks awfully like the pic on the left http://www.new-rfid-concept.com/rfid_and_nfc.html.

Noticed the pattern too. S'why I'm curious what it's for.
Huh, but why would they put an rfid chip in a phone when android is supposed to start using nfc? My guess as to the contact points are wifi antenna contacts. I noticed I get amazing wifi pickup from routers far away. Much better than any other device I've used. Although, no signals loose reception quality when the back plate is off, wifi, cell, gps. Idk. Haven't tried bt though.

Doubt it's an actual RFID in the back cover. It's just that little patch on the back cover looks very much looks like an antenna.
Really, I don't think it can be something. A mp3 player I owned for 4 years have something like this too. It's most likely to be something like digital ground just to keep the voltage stable...
Shammyh is correct, it is for NFC.

What are you saying? The captivate secretly has NFC? Seems a bit far fetched since found this yet. Would be cool though.

i know this thread is old, but i was searching for the same thing today. after i read this thread here, i found this, explaining some roms that support the chip:
"... Audience Chip support (Captivates have a special chip added that increases call quality... if it is used)." loraqu
@ http://forums.androidcentral.com/t-captivate/111137-cyanogenmod-7-vs-serendipity-vii.html
so i guess its like those weird sticker things they used to sell on tv that claimed "its like adding a 5 foot antenna to your phone!" and im assuming everyone knows by now it cant be nfc because the backplate is metal. i found it interesting, so there it is if anyones still searching.
I was rather disappointed in the GPS performance of my shiny new Desire S...
It was so erratic, I loaded GPS Test app to check out the signal-to-noise ratio.
Then, just out of curiosity I took the aftermarket outer case that I had bought (rubber+plastic) off.
The GPS signal increased dramatically and many more satellites appeared. This effect IS consistent.
I was thinking of modifying the case by cutting a hole in it to improve GPS reception, but I'm not sure where the GPS antenna is located.
I know that phone and WiFi antennas are in the battery cover, but I would suspect that the GPS antenna probably is not.
Anyone know where it is positioned ?
Thanks,
- Steve
Not sure about the Desire S, but I had Legend before and the GPS antenna was behind the camera cover. It was connected to the plastic cover in a similar way the WiFi/phone antenna connects to the battery cover using small metallic terminals. I used elimination to determine which was the GPS.
Interestingly enough, I do not suffer from poor or erratic GPS performance on the Desire S. I get quick fixes from plenty of satellites even in less than ideal conditions, eg, a moving subway train.
Slightly off topic, what I did notice though (using GPS Test) that even with 12 strong satellites, the highest accuracy ever achievable on the Desire S is 9 feet, whereas every other HTC phone I've tried (Legend, and even the very budget Tattoo) goes down to 6 feet accuracy. Wonder why that is?
Oh, maybe it is build into the cover, then. I'm used to seeing ceramic block GPS antennas which never look thin enough to be built into a battery cover.
At least my GPS works quite well too until I add the flexible case on.
I was annoyed that the case attenuates the signal, because it was a particularly expensive and otherwise beautifully made one.
If nobody knows where the antenna is, I might have to do some experiments too.
As for the ultimate accuracy of 9 or 6 feet.. Well I suspect that it's just a subtle difference in the firmware. I don't believe that kind of accuracy is reliably achieveable anyway unless you use Differential GPS techniques - And I presume Qualcomm doesn't add that kind of luxury to their phone chipsets.

An update :
I got a GPS lock, and observed satellite signals using GPS Test.
Then I put the DS into airplane mode so no radios were active to mess things up.
Covering the lower part of the case all over (including battery cover and screen) with foil has NO EFFECT.
Covering the upper part of the case around the speaker causes GPS signals to fade away.
The hard plastic cover supplied with my case kit has NO EFFECT.
As soon as I apply the rubber part of the case kit to the upper part of the DS, the GPS signal fades.
Conclusion:
The GPS antenna must be in the upper part of the case
It's the rubber part of my case kit that reduces the GPS signal.
Hope this is if interest!

So the GPS suffers from the death touch as well like the wifi since the antenna is at the same place.

erm.. I thought that the WiFi antenna was in the battery hatch with all the others ?
I reckon that the GPS antenna is probably the other end of the phone up near the camera lens. I've never had a problem with it being obstructed by hand, only by my damn expensive case!
Wifi antenna is at the top too but i thought people already knew this from the famous wifi death touch/grip?

I'm so sorry to hear about your problem.
I have many years of experience with different types of GPS and although the DS is not the best I have ever seen, it is not too bad (without the extra case, that is!) Only dedicated GPS units like SIRFstar seem to beat it, and that is understandable.
Do you only get about 4 satellites with the DS out in the open air with no buildings around? It can not work well indoors or sometimes if there are large buildings around.
Have you tried using "GPS Test" or a similar application to clear the AGPS data then load it fresh again?
If all else fails, perhaps your DS is faulty?

Thank you so much for help me
I tried everything i can do i checked outside and on my house. i used gps test, gps stattus, gps-fix. And still problem
I think my DS is faulty. so sad.
My friend have one, and it work better.
An update :
I emailed the manufacturers of my rather expensive case explaining the problem.
They seem to have a good customer service department - I got a speedy reply but they claimed that they were not aware of any issues with cases affecting GPS reception. They say that all their cases are made from the same materials so they would have thought that if there was a problem, it would affect other phones too.
They have promised to pass my information to their engineers - I hope they might get in touch with me!
In the meanwhile, if I can find out precisely where the GPS antenna is on the DS, I might try cutting a gap in the rubber for it. I'm sure that would help.

Case
I use a Case Mate Barely There Case and it doesn't affect GPS, wifi or phone as far as I can tell.
Rick Ohlendorf
I use the Case Mate Barely There Case too, but I doesaffect the GPS for me.
When the case is on, getting a location lock in Navigation is impossible.
When I take it off, I get a lock within seconds.
if you look at the back of ds, upper portion there is 2 small holes, ive always thought that its a hole for wifi and gps. one hole below the flash led, another on right side of speaker.
then on my capdase alumor case, it also has a hole for those 2 hole, so it might confirm my theory that those are antenna holes thats why capdase also made holes for them.
I use a case-mate tough case, a much thicker dual layer heavy duty case, and I get a gps lock just fine with it on.

I would like to extend the GPS antenna.. I just can't open the cover, how to do? I only managed to scratch it a little..
I have no case,but the signal is very bad.I turn on airplane mode and GPS,it often takes half an hour to get my location...
Best accuracy is about 5 meters.
The cover needs a stick.HTC used some glue.
So I bought a second hand MT4GS today, but the buttons on the face of the phone don't work - it came rooted, s-off, with some buggy ICS Rom installed. I just installed Bulletproof in the hopes that it was just the other rom causing the issue, but the buttons (home, menu, back, genius) are still non responsive. The corresponding buttons on the qwerty slider work fine.
Any ideas or suggestions? Would it help to try flashing a zip to map those front buttons? Since they don't work in 2 roms, is it something physicial?
I would appreciate any advice you could give me, whether its a certain way to try and remap the keys to force them to work, or a rom that might fix it, or maybe a kernel that would be most compatible with a quick, stable rom with full camera features? I really don't care about being on the bleeding edge or having ICS, I just want a stable, every day use rom.
Thanks much!
Almost certainly physical. The flex cable inside has 5 dangly little fingers that go down in that area for the 4 buttons and the track pad. Very easy for that to get gummed up, and not an easy thing to fix (because this phone is kind of a pain to take apart). Still, you can find some videos on YouTube that show how to disassemble the phone. You can try it. Put it back together carefully enough, and those buttons might start working again. (If you're unlucky, you might need a new flex cable.)
OK, do I need anything besides standard precision torx to open this phone up? I haven't really peeked inside, since we only got it a couple hours ago.
Also, I noticed that the home button on the physical keyboard sometimes takes me home, and sometimes selects things, depending on what I'm doing - talk about weird! Either way, it's still better than my ancient and fading G1 I've been stuck using the last couple days.
So if I open it up, do I just want to blast it with canned air, or is that a big no-no? Get a little soft brush and brush around the fingers? Tell it sweet nothings and tuck it in bed?
Edited to add:
Aaaand while I was busy typing and researching, my husband is cracking it open like a kid opening a Christmas present - wish him luck!
Bah humbug, just a note to let you know that we got to the 8 screws that hold the keyboard to the sliding part, and 2 of the phillips screws are stripped. So we're putting it back together until tomorrow night, when we will try to figure out how to get those 2 screws out.
But hey, at least we took it almost all the way apart, and got it back together, and it is working as well as it was before - if we didn't totally break it, then we're still ahead of the game!
So now I'm looking for advice on the following:
1) best way to clean out those button flex cables (air, small brush, ?)
2) ways to keep this phone clean inside - previous owner must have worked in a dust bunny factory, based on the dust I found inside the half of the phone we got disassembled. Then again, I live in a desert, it's to be expected?
3) super-stable rom/kernel combo that also gives me the camera app goodness that this phone deserves (And be honest, if I need stock to get the camera working, I'll go to stock).

Compressed air or a small brush should work fine... If it is just a connectivity problem caused by dust or dirt or whatever.

The only way to really keep it clean on the inside is to take it apart and use some compressed air or a small brush to get rid of all the dust... Doesn't matter where you are located you are gonna get dust inside of a phone that has no dust covers... You can see if they make any cases that have dust caps for the ports (I'm not sure if there are any for the MT4GS or not... haven't looked...)

For the awesome sense camera I would recommend stock or if you want ICS then one of the Virtuous roms. Either Primmadonna (ICS+ Sense 4.0) or Inquisition (desensed with sense camera). I'm sure others have other opinions, but those are the only roms I have used... Well that and CM9 which is basically fully functional although it will never have the sense camera, but the AOSP camera isn't too bad. They are all super stable as well.
Those 8 little screws are easy to strip. They are only a couple of turns each, but if they don't budge ... well, I've got a broken phone just like that that I can't fix. If you figure out a way of drilling the out or whatever, I'd be interested to hear.
The dust in these phones is a well-known problem. In particular, dust can find it's way under the glass, and it's a complete teardown to clear that out.
Were the screws stripped when you got there, or did you do it? If someone had the phone apart before, it could be that the little flex cable fingers are just not in the right position. If that's the case, you just have to do it right. (Easier said than done since it's kind of tricky to work on it and keep everything positioned while you close it up.)
Those 2 screws were stripped when we opened it - we've tried a couple things and still haven't been able to get them out, but we haven't tried the trick of dabbing superglue on a screwdriver and letting it dry in the hole yet, and we haven't tried one of those screw extractors that is like an extra sharp screwdriver. We tried cutting a new slot with my dremel, but the cutting discs I have are too soft for the screw heads, we need a diamond cutting disc, I think. We also tried one of those drill chucks that has the 2 ends for reaming a new hole and unscrewing, but my husband is afraid to drill through the phone, and the chuck doesn't fit in my dremel.
I'm pretty sure whoever had the phone before me tried to fix it and gave up, that's why we were able to buy it off him for so cheap. I don't mind fiddling around with it, since the actual phone bit works just fine.
If I ever manage to get these stripped screws out, I'll let you know what works!
Those screws are definitely short in length, as you've seen from their companions, so I am also leery of drilling a millimeter too far.
Another thing I've contemplated is carving the plastic around the screw head so that the screw no longer holds anything in place. Haven't been bold enough to try it, though. I figure after that I would be able to get a grip on it with needlenose pliers and twist them out.
((My phone with the stuck screws is a water damaged phone that I bought used. [[Seller said "I don't know what happened to it", but, uh, it's a bit obvious once you look inside or even look at the sticker.]] Screen was flaky and I was going to take it apart and stare at it til I ran into those stuck (and rusty!) screws. Luckily, after a few days delay for head-scratching, the screen started working perfectly. I like to think of it as the Universe finally giving me a break.))
Would a cell phone repair place have better ways of getting those stripped screws out? My husband said I should find out what they would charge to open it up, but if I can't get the screws out, how would they do it?
And it's nice that your soggy-phone decided to start working for you, it's a pain dealing with wet phones, sometimes. My neighbor dropped hers in a big cup of soda once and I got to have futo leaning it out to help prevent sugar/corrosion issues. I only managed to keep it working for another 3 months, but by then she had already dropped it into a toilet.

For wet phone the best thing you can do is to use milliQ water (distilled will do also), put the phone in it, it basically removes any ions from previous fluids (take the battery out!), then let it dry out (24h should do), please battery in and use... Worked for me few times...
Btw. Good rom is virtuous inquisition or Primadonna, cm9 did not work for me so good, too many unfinished things...

Hello, I have a problem. Hoping someone has an answer. I have a Verizon HTC M8, yesterday I decided to disassemble the phone to just see what the insides look like, I didn't touch any other part, I tried to remove the top motherboard but I stopped because any further would damange the top board. Anyways, the GPS was working fine until I took the unit apart.
The problem: GPS location on Google map is at least a block off (tried different map apps, all are offset) and is facing the wrong direction. And GPS following is very very slow. Now I don't know if it has to do with an GPS antenna or what, maybe one of the prongs is not touching antenna, I've taken a photo of the phone from inside and I would like to know which area of the phone is exactly the GPS or maybe causing the problem . I've also attached a photo of the GPS problem, you can see in Google Maps navigation the pointer is wayy off the direction area. Please advise.
Question: What part may be causing the problem? (my guess is its the copper prongs from A-G).
Please help.
Thank you!

In my opinion, this phone has kind of wonky GPS reception anyway. It's hard to tell exactly what's causing it, but my guess is that it has something to do with an unwanted contact, or the antenna itself, touching the metal casing directly. Also, You may have possibly loosened the connection of the GPS antenna when you played with the motherboard a little.
I'll try to find some better board schematics from the motherboard, maybe tomorrow when I have time. I haven't really been able to find some good diagrams on the actual phone internals itself. This phone is really difficult to take off and not too many people attempt it.
I would try to make sure that the internals are properly shielded when you put the case back on, and try to keep all of those contacts covered as much as possible when you throw the case back on. See if you get better GPS lock or if it fixes it all together.
Edit: Actually I changed my mind, I think all those contacts are supposed to contact the case to amplify the signal. Try to get all the contacts to touch the case as much as possible when you reassemble it. I think it's either the connection from a-g area, or on the bottom half k-n or even the q connector. Is your WiFi or NFC giving you any issues as well?

@ Badusername, Thank you for your reply . Yes everything else (wifi/nfc/bluetooth) works perfectly fine. The accelorometer seems to be fine as well. Only part I try to remove/touch was from A-G area motherboard but that was held with adhesive so I didn't touch it any further, I didn't touch any other part. My guess is it's A-G area but not sure exactly which one is the GPS antenna so I can try to adjust it (if possible).
I jave the exact same problem. Did you figure anything out yet?
Any Updates?

Did you bend any of the copper prongs so that they no longer touch their antenna? That's usually the problem.

Not sure which prongs you speak of. I reopened it and all antennae look connected and right but still no go...

Can't find a schematic anywhere that shows which antenna or prongs are gps related so I don't know which prong or antenna to mess with. I'm surprised there are no basic schematics anywhere...

I believe it's in the top board so make sure the ribbon cable is secured and not damaged. The metal prongs usually need to make contact with the case itself which often has the actual antenna stuck to it.

Thanks for your help so far. Checked all prongs and ribbons on top left and they all look normal. They all still have a spring to them so that theyll touch the contacts on the back of the outside case. I'm out of options without finding exactly which part are gps related....

Hi sorry for the late reply, fortunately I was able to replace it with HTC. I would still love to know the solution. Good to know for future reference

Your welcome. Glad to help.
Is there any way to purchase the gold colored motherboard clips/pins that make contact with the case for the GPS module. While attempting to fix mine, the clip broke. I was looking to purchase this clip to attempt to solder it back to the board.

I'm in the same boat. I don't think there's a way to replace the clip itself, only the board that has the clip on it. It shows up as a result for "HTC One M8 Motherboard Flex Cable". Here's the one I'm buying, it's around $60. You can see the little gold tab in the picture for it. Looking at that board's location on the phone, it looks like you'd probably have to remove the motherboard to get to it and replace it. Sounds fun. I had my phone apart for a relatively simple USB port replacement.

I know this is raising the thread from death but I too broke my tab off for the gps. I was able to fix it using a trimmed piece of thin sheet aluminum that I salvaged from an old Airport extreme. I trimmed it down to the size of the tab on the motherboard and used some conductive adhesive to stick it to the solder pad that the old copper tab was attached to. I then trimmed to down to length to touch the casing when the phone was reassembled. Its been working great now for a few months and its actually a much sturdier piece of metal. I can't say objectively since I don't have data to back it up but it feels like I get a faster GPS lock now.
