Possible solution to GPS problem on Nexus S - Nexus S General

Hi,
i've tried just about anything to improve GPS singal on my Nexus S, i was so desperate i even thinked about selling it. But by accident i've found something interesting.
When you remove battery cover signal from GPS is really good, usable even indoors 1-2 meters from window. When you put cover back - it suddenly drops. Here's the best part - when i use different cover directly on the back of the phone, WITHOUT original battery cover (i have thick back case which you put on battery cover, anti scratch thing) signal was just as fine as without any cover!
Then i tried covering back of the phone with a case from another phone (Galaxy S) and signal was fine.
So the culprit is NFC spiral which is sticked to the battery cover. I'd like to take it off, but im not sure if it is possible to stcik it back in case of RMA or something.
I'd like you to try this simple experiment and tell me if your phones suffer from the same thing.
Thanks

hmm interesting

Lol wow with cover on I get 2-3 .. without cover 3-4.5 ... lol

What about turning NFC off?

Today i took off NFC antenna and it didn't work, which is strange. Now the culprit is whole battery cover. As i said i tried different cases and GPS was working fine with them.

Hello,
in our german community we discuss this problem, too. The Problem isn't the NFC antenna, it's the backcover! Some user tried with another cover from ebay: http://www.ebay.de/itm/250846706756?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 and this seems to work better!

Yup, that exactly what i considered. It's really funny, because original battery cover is making GPS works like s**t.
If that cover form ebay is really working i might consider buying it, i'll try to read original thread, thanks.
Have you tried that cover? My German isn't that great and neither is google translate. But from what i read this is really working, but i don't know how well.

im guessing NFC wont work without the stock battery cover

when did this GPS problem started?
it must be new...

Hehe. Put your NFC antenna back on. Google wallet is awesome.

Hey guys
I have my Nexus S (Blandroid + Trinity T144) tested just now, and now I only realize the GPS unit is on the right side of the phone.
Take off your cover, you should see a black, duct-tape like module pasted on almost 3/4 of the right side of Nexus S (the side where power button is located). That should be the GPS unit.
Tested with cover on, landscape with right side of the phone pointed upwards, I gained a score of 40~41 in one or two of the satellite in my view (GPS Test by Chartcross Ltd). When I test it with cover off, I gained a score of 45~47 in a few of the satellite.
Conclusion is, if you need a better GPS signal, you will need to hold it landscape with camera pointing to the left. Portrait mode will not works too well I guess. I wonder how Apple products can gain locks near instantly.

that's what i always do when i want to use GPS for navigation, pull off the battery cover.
it's almost impossible to get a fix with the battery cover on.

Humm I really wanted to delete this post but there isn't an option

Wow, i tried to get gps fix in my home without cover and it work!

HELP: Battery stuck in DHD and won't slide out!

Man is this the stupidest problem ever...
The good news: I finally got my DHD yesterday...
The bad news: The battery cover is as bad as I've been hearing. For some reason I couldn't put it back on. So I pushed the Battery as far in as I could in order to put the cover on. The phone works great, but now the battery is stuck inside and won't slide out by itself and I don't know how to take it out
Please Help...
Put your fingers flat on the table, same width as the battery door.
Rest the DHD on your fingers (so that the battery door is facing the table.
Raise the DHD an inch or two and bring it down on your fingers (not so hard that it hurts).
Keep doing this, the battery will work its way free and drop onto the table.
I'll add a pic in a sec...
Thanks James, this definitely sounds very doable; I'm giving it a try now!
The battery has moved about half an inch now!! This is working *jumping up and down with joy*
I got the battery out!! Why does everyone else's battery just seem to slide out by itself? I thought it was because I pushed it too far in, but even when the battery is half way out, I still have to pull it out with some effort...
Maybe my phone just has a lot of "friction"? When I watch those YouTube videos, everyone seems to glide their fingers smoothly across the screen, but when I do it, it feels very fricative...do you guys put on hand lotion or something...
Do not press the screen too much, only a slightest touch is needed. Also if you have moist hands, it makes swiping the screen harder.

Probably because its a new phone. You have to play with it a little bit until the oil from your skin lubes up the screen. Then its all slidey slides.
I had a similar problem with my first DHD... part of the the plastic wrapper around the battery had folded back on itself along the forward edge of the battery. That caused the battery to get wedged inside. A little trimming of the plastic wrapper with a craft knife fixed it... YMMV

No you can't - the WiFi/BT antenna is in that cover .
would've given you some extra grip tho
Now seriously, if when u look at ur battery there's no visible flaws that u can safely and/or easily remove and if your screen keeps giving you the finger in my opinion you should return it for a replacement. There's been enough faulty hardware cases, the folks at HTC know the drill by now. If that's not an option, sell it on ebay ( or your local online market ) and grab a new one;]

I got an aftermarket battery stuck in my DHD and had basically given up on getting it out until I found this thread. Nice work! Worked a treat after tapping it for what seemed like a couple of minutes.
Slow and steady wins the race!

GPS Problems? Poor Reception? Accessories to Blame?

Just a heads up to anyone experiencing GPS and or reception issues, if you have any aftermarket accessories, be conscious that they may be the cause of your problems.
I've had GPS not been able to lock for a while now, and it turns out that the sole cause of this was an aftermarket metal battery cover. As soon as I put back the stock plastic one, I got a full 8 satellite lock within 20 seconds.
Any metal case, cover, bumper, etc could be having a negative impact on your reception and or GPS. This was definitely the case for my I9100
Yes! can confirm this I had the same issue a while back.

Yup, general thing.
Had the same thing happening on the HD2 just like alot of other people who bought the rubber like protection things when they just came out.
Actually it just not only blocks GPS but also wifi and mobile signal a bit which results in a bigger battery drain too.

It was quite annoying to realize that I've gotten lost a few times the past few months all due to an accessory I paid money for
Makes sense why early iPhone 4's had problems with reception, due to the metal housing
So it's just the metal cases? I've a gel case for my SGS2 and it works great with it

It's not the iPhone's fault brother, like 'he' said; "You're holding it wrong."
On a serious note, the case definitely have impact to signal and heat dissipation. Once upon a time, my HD2 was plagued by signal+heat issue due to some crappy case.

I get you cand send e-maild but sms', no. . Since I don't know where you are from, go to your local network operator store and ask someone to give you the right number for message centre. This should be stored on your SIM card but it seems to be a little problem.

[Q] nexus 7 WiFi problem

As I was walking my nexus 7 slipped out of my hand and fell on the floor. A couple of minutes later I tried to turn on WiFi, but it couldn't get a strong signal. However if I'm close to the router it connects. Any suggestions on how to fix this?
You probably only need to pop the back off, make sure it's not full of grit and fluff, and put it back on again.
Just run your thumbnail around under the back bezel, starting from the middle of a long edge - knives or screwdrivers won't do the plastic any good. Try to avoid touching components and contacts once you have it open. Static won't do the components any good, and fingerprints aren't great on spring contacts.
The cover will easily clip back on with gentle pressure at the edges.

Well.. I'll try to explain it. It's rather simple. When you see the nexus 7 without its lid, search for the two little gold raised up thingies that connect with two little plates on the inside of the lid itself. I just raised them a little bit with my finger so that they could have better contact with the plates. Then just close it and voila. Im sorry for not being all technical with you xD

Interesting. Do any of these spring contacts have anything to do with wifi signal strength?
I own 2 first gen nexus7 stock kitkat never rooted... Both suffer from wifi authorization issues and signal drops..
I just grabed one after reading this, its wifi as usual was not connected. I popped the back off and adjusted all the contact springs. I think there was 6 or 8 of them.. Anyway i got wifi connection right away.. A fluke? Or do any of these springs and the back cover effect wifi?

Sorry for this late reply. When I fiddled around with it there were only 2 springs.. :/
No . Problem either way my problem came back.
The fix came from setting up a different security option on the router.

Apparently a really reliable/unexpected fix to GPS woes found on Reddit...

GPS issues on the Note 4 are well known and not limited to carrier. You will find all sorts of crazy fixes out there, but I will tell you what finally worked for me.
I noticed that every time I went to take a screenshot the GPS would suddenly snap back to working. After some messing around I realized that holding it by the sides with a little pressure gets it working. Basically hold it the way that Steve Jobs told you you shouldn't hold an iPhone and squeeze a bit. That always gets my GPS to work within a few seconds. It sounds crazy but for me I've confirmed it absolutely works.
Basically Samsung sucks at GPS in general, and especially with the Note 4. I think the receiver is using a poorly manufactured antenna that is the wrong size or something, and by attenuating the signal a little bit you can get it to clear up. It's like adjusting you rabbit ears and having them only work when you stand in a certain position... if you are old enough to remember doing such things.
Give it a try and report back.

Interesting. I'm really glad I'm one of the lucky ones that doesn't have any issues.
Is the hardware part of it loose or something?
I've yet to try it but I do believe it is an antenna issue. Maybe made worse by cases?
If I place the phone in the dash cubby of my car, it will lose gps signal.
But even when I have it on the seat next to me, it sometimes can't locate me directly and jumps.
I thought GPS status calibration would fix but I guess you have to do that every time you reboot?
It is my only complaint regarding the phone honestly.

I'd like to think for the most part I was one of the lucky ones but just yesterday morning I was using the navigation. It found me and plotted my route but when I started moving nothing happened. I squeezed the top of the device and it kicked in. The only thing I have been doing different is not using my case when the issue happened. Of course as tight as my case it it could be simulating the same situation as me pinching it. Or it could have been the initial cause for needing to pinch it.
Probably loose hardware indeed.

Yes, it's almost certainly a hardware issue... check out this post http://forum.xda-developers.com/showpost.php?p=61755100&postcount=272 and the thread that it links to.

Yup. The GPS test app would show 20 satellites in view, and none in use. No lock ever. I pushed on the back of the phone and it locked right on. It world's every time my gps flakes out.

Happy to report my GPS on Note 4 gets instant lock every time. Use a Samsung flip cover that is also a back replacement.
I have HORRIBLE gps signal... and the thing that sucks is I need it for work alot.. sometimes I'm using it and the signal starts blinking because it lost signal..and I won't get it back I leave an area or I just won't get it at all!! I hope the 5 has a much better antenna build..
Like others I'm having terrible luck with my GPS but it's only been over the last 3 weeks or so. No updates, no damage to the phone it just loses the lock on the satellites. I've tried every trick in the book with no luck. I need to call T-Mobile but haven't been in the mood to hear "we haven't seen this problem before" and wasting time on the phone with them.

Install "GPS Test" to see. I have Samsung Alpha and it get lock inside the buidling while the N4 sees nothing. I am mad. I hope N5 will be better on the GPS.
It's not a fix but what I do since I use gps for my work I put the phone SIDEWAYS in my cluster area and it almost instantly picks up gps.. it's what I have to do to get service if not it will be almost unusable. .hope that helps
I was reading about putting pressure on the back on another post and once I do that my phone starts working great... what can cause it to do such a thing?

I've been using it and I will get the coordinates then I will loose signal without moving. It's very inconsistent. The frustrating thing is it seems to be only over the last few weeks it's been happening.
I also had trouble with my GPS. I constantly get the "GPS signal lost" message, however this past weekend I tested and it seems that I get the problem when I put the phone in a certain position -on my lap for example or facing down. I have a Galaxy S5 and I don't have any issues at all.
Once I put the phone in the car mount, I don't have any problems. I guess is an antenna issue as others mentioned.

i9506 GPS not working at all

Hi All,
I have an i9506 previously stock 4.42 (Hungary I9506XXUCNI1 firm), later switched to I9506XXUBNA2 then 9506XXUDOJ2 which now serves base for kyasu's 13.0-20160323-SNAPSHOT-ZNH0E-ks01lte.
A month ago I realised that the GPS finds position really-really slow - if it finds any after 25 km ride.
Even if it is able to find the position, it looses quickly.
Waze and iGO Primo are unable to work / navigate.
I shortly switched back to stock ROM but the problem stayed.
Do you think that a custom ROM could have something to do with the GPS problem?
Any tips how to narrow the root cause possibilities?
Maybe the GPS hardware is faulty? In 1,5 years the phone had no more than 5 ground hits. In theory this could cause a faulty GPS...
That is caused by the GPS not making contact with the antenna on the chassis of the phone.
I managed to fix it myself by unscrewing the back and removing the whole back panel off (by carefully I clipping the frame). The GPS antenna is located on the top left corner. Carefully using a flat screw driver bend it up and then put the back plate back in and screw it in tightly ensuring that you don't over tightened and crack any of the plastic.
After that, the phone would get a GPS lock within seconds.

Yeah, exactly. In the meantime I asked Samsung support for a repair. They replaced the whole middle plastic part of the phone (including the antenna).
It seems that problem is solved.
Thank you!
