ive noticed i my gps signal constantly drops out while navigating and the only way to get it back, is to hold it in the dash with absolutly nothing blocking it overhead. With my OG evo, i did not have any issues whatsoever, always a strong signal. does anyone else have this problem? im considering replacing it, unless its just a software issue that may be fixed in the next firmware update.
Same issue here.

Everyone's issue?
I want to love this phone but it seems im going to return it soon one i get it and get the optimus3d.
I do not want problems with any hardware or antenna.
I have some ideas. In /system/etc/gps.conf there are some lines that look like if changed would help. I changed the intermediate accuracy level to 100, and where it said disable.agps.in.wimax I changed that to false. It may also benefit to change the allowance if intermediate position to zero. And old hack we used to use was to add the line QOS_ACCURACY=16, but I think that's the same value hack as the one I just mentioned. Feel free to try these. I don't use gps much, so my modifications may go unnoticed. Ymmv

Waaahhh. How in the living hell do you know that an UNRELEASED device has "no GPS issues" - for real. Also, have fun with the awesome monthly premium you'll get for AT&T and their awesome network If you can develop a little patience, I would tell you HTC has awesome build quality, and the dev support for this phone is great, so GPS will get better. Maybe not by tuesday, but sometime.

I live in the netherlands where its already released and im getting it tuesday. Your posts doesnt make sense.
You cant improve hardware with software...you can tweak to make it work a bit better...but it doesmt chance the hardware...
well the thing is, i believe the gps hardware is just fine. its probably the same chip they use in other phones. hopefully were just a few tweaks away.
Same exact issue.

do you use your Google navigation often? If its an issue thats not widespread, then ill probably just take my phone. I just dont feel like going through the hassle of getting a new phone if the refurb is going to have the same exact issues.
I have the same issue. Constantly losing GPS when I didn't have this issue before in my area on an Epic 4G. Sprint TeleNAV and Google NAV do it.
I’m an extremely heavy GPS user. I used my Evo as my GPS every day for work, and now my Evo 3D. In the year that I had the original Evo, not once did I have an issue. And by an extremely heavy user, I use it to locate 20-40 (depending on the day) locations a day, every day.
I bought the Evo 3D on launch day, for the first week or so the GPS worked great, it lost the signal once or twice, but I ignored it. Then one day it kept losing the signal a lot. I’m talking like 5 times in an 8 mile stretch on the same road. It started taking forever to recalculate, there was an extremely noticeable lag (it would say for example, my next action was a left turn 1.3 miles away when I already passed the road I was supposed to turn on to). Not only did the signal drop out while driving, but it would drop out while just being parked, and then it takes forever to require the signal. And my personal favorite when your five miles into a 17 mile long run ON THE SAME road/highway it will just randomly recalculate. What’s up with that? i assume these are the same type of issues everyone is having?
Now I took the phone back to the Sprint Store, I was within 30 days so they swapped it out for a band new one for free. The new phone worked great for about 2 weeks, and the same issues started happening, but a lot less frequently, it was tolerable, but so far this week it has been pure hell. This afternoon I lost count, but I was up to 157 instances (this week alone) where the GPS has lost the signal, rerouted me randomly or incorrectly, failed to properly update me of my next action, or just took forever to acquire the satellite signal. This week has been extremely aggravating, to say the least.
Here is one thing I noticed this afternoon, I’m not sure if this is just a fluke or what. I always keep my phone connected to a car charger when driving. For some reason I unhooked it and was running on battery, the GPS worked perfectly to get me from my last two stops of the day, back to work, a total of about 60 miles worth of driving. Not one drop out, not one bit of lag. Prior to that I couldn't go 5 miles without some type of problem. Tomorrow, I will be in an area I’m sort of familiar with and won’t need the GPS much, but I’m going to map out my stops anyway just see how it behaves on battery, until the battery gets low. That final 60 miles today took me from 100% to 55%.
I'm sure everyone knows about the GPS bugs that plague the first generation Galaxy S. I've read the SGS 2 reviews and they said the GPS issues have been fixed, but can I get some opinions on whether anyone experienced any GPS issues? Is the GPS on the SGS 2 as accurate and good as the one on the iPhone 4?
Works fine. Faster lock than my IP4.
Its much faster than the Galaxy S1. I found the GPS to be close to useless on S1. On my S2 its close to perfect

Works great and picks up signals inside buildings.
I had the sgs1 for about 6 months and now the sgs2 for about 3 weeks. I was soooo disappointed with the first sgs and like you I was unsure if I wanted to give the 2 a try...
Well I read a bunch and it seems that most people are happy so I bought it...
I can say with out a doubt that the GPS is way better on the 2 than the sgs1. I could not use Google navigation at all with the sgs1... it was useless and could never lock on and would have me blocks away from where I was. I've used my sgs2 GPS with Google navigation on more than a dozen trips /drives and it has always been spot on and never had me in the wrong location.
I will say that lock times are very slow when Im driving

I run every other day for an hour or two, I use runkeeper, also when out hiking I use mmtracker to read my o's maps, I can safely say especially with runkeeper the gpx routes recorded through the SGS2 are far more accurate than the iphone4 even managing to stay accurate whilst running through the forest, actual initial cold starting is about the same if not slightly faster with the sgs2. Oh yes and practically every time I recorded a run with the iphone4 through a certain part of my forest run it would create a spike where I was apparently running at 250mph hmm not sure I am that fast, but the sgs2 always keeps an accurate smooth record, hope that helps
for me, flaky. some days i'll get a lock within a minute and then it's fine. this morn and yest - takes ages to get a lock.
basically, ymmv
Download FasterFix. You can choose from a list of servers. Choose the country closest to you or, if it is in the list, your own country. This way you'll 'half your fixtime' so it connects faster to GPS-Sat.
It's like using the aiding sensors (e.g. WiFi).
I get a fix in >10sec max.
Hope it helps.

What is the average time for a fix, for you guys?
Sent from my GT-I9100 using XDA App
Mine takes between 10 seconds and a minute. Sometimes it just sits there doing nowt lol.
Xperia X10 used to lock in 10 seconds every time, but the rest of that phone was slow lol
The only time I have ever had a problem getting a fix, I simply opened up google maps and it seemed to get a fix instantly then returned to my other gps application and all was ok.
First thing in the morning outside fix within a few seconds
Indoors sometimes can take a little longer, but never more than about 10 seconds
I use GPS a lot

I guess you said this to clarify that you've got good statistics, but a very interesting thing is that if you use the GPS often you likely get shorter fix time
The reason is that if you used the GPS recently (within hours) the cached GPS info is more accurate so the GPS doesn't need complete messsages to determine the position (it takes 30 seconds to send one complete position message from a satellite), and if you get interruptions you need to wait even longer, that is why it sometimes takes more than a minute to get a fix.
A-GPS also helps fix time in many cases.

Same thing happened to me.
Absolutely brilliant.
90% of the time it gets a lock within 30 secs , there's been sometimes when it needed a restart to get gps working properly but that's down to an app I was using previously which messed things up a bit, but on the whole I very happy with it.
The seamless integration with google maps is great. The external speaker is plenty loud & clear enough to hear the instructions but would like a less robotic sounding voice, re routing is quick & so far its been 100% reliable.
I have a built in gps system on my Land Rover but I almost always use the SGS2 gps over it. I used to have the SGS1 but the gps on that was a piece of crap. Gps on HTCs, etc, are probably just as good/better/worse, I don't know but one thing I'm sure about is the speaker volume would never be as loud & clear as the SGS2.
I get a lock up to 4m accuracy. My Captivate always had about 1500m accuracy and couldn't use it. Using navigation works perfectly on my sgs2

Excellent
Like others here, i suffered from the original SGS gps nightmare
SGS2 gps has been great for me, able to use google maps/navigation/RAC app all without problem
I didn't realise how much location based services I used untill the problems with SGS gps clearly highlighted this. Now, with my SGS2 all is good.
Is there an app like the LBStesmode for froyo that I can use to change/check the gps settings?
There've been a fair number of positive results with the Vulcan Nerve Pinch, so this is to quantify the findings.
I can't edit the poll, but please take "permanent" to mean 2 days of regular use. So if a single application works for at least 2 days, then vote this, else vote temporary. If improvement didn't last for 2 days, then indicate how long it did last.
Detail of the issue and of the Vulcan Pinch:
The Prime's three antennas use pressure contacts (pogo pins) that can be marginal, causing weak wifi and/or weak or no GPS. Pressing/pinching on the three locations, or along the Prime's top edge (landscape), can improve reception in many cases. Per the poll so far, about 25%.
See pics in below link to find locations of the antenna contacts,
http://forum.xda-developers.com/showpost.php?p=21847680&postcount=52
Well I just did it about 3 hours ago, so I don't know how "permanent" it is yet.
But, so far so good.
You're holding it wrong
unfortunately, no. my gps still doesn't see jack and wifi still slows to a crawl when there are walls between prime and the router.
Well what do you know, they named a Fix after me.
To what I understood there were two different kind of problems for GPS :
1) Some people had no GPS satellites detections at all.
2) other people had satellites detections with locks but at a low reception level.
I guess this fix is only working for the case number 1. In that case, people are now joining the case number 2.
For people who were already getting a few satellites (case number 2), it will change nothing as the back cover is still the same ...

I pickede mine up Saturday from BB (Orlando) and B1 Series with no functional GPS but amazing Wifi. I have even went a little father to beat it againest the steering wheel and see if i could "jar" something to work a little better. With no luck GPS has not improved. Wifi reception is just as good as all my other devices. Does not fall of as quick as some of recorded.

Spock of Star Trek ~ How to render someone unconscious
Pinching didn't help. My GPS was fine until the last update. I ran GPS test before and after the update since the update was to fix GPS. I wanted to see the improvement, but I only got to see how it made my GPS completely unfuctionable. The same exact thing happened to my Dad's Prime. I sure wish Asus would get their **** together.
I tried the vulcan pinch a few days ago but did not affect GPS. I even drove block to block to see if google maps updated my location but no go. I dont think it affected my wifi either but I think my wifi was good to begin with and had thought it was bad as I was basing it on the signal bars.
Got a c1 model from BB last saturday. After ics update and vulcan pinch, Gps Went from zero sat to 11 views with 8 locks indoor. Unfortunately, view/locks are intermitents. WIFI didnt improved and is quite slow but stable. I noticed that i cant switch on/off the gps device from anywhere in the settings since the ics update, but it was still available before the update.(?)
Got my squeezer from Best Buy (serial BC). Wi-fi working fine, 4g LTE is sweet. Gps works only outside, but locks in and out with movement, bad. All the pinching for not. Dock works great. I will keep returning trying different units until Best Buy bars me.
BC model from Comet (UK) wifi works fine but had no GPS signal prior/after ICS update. After the big squeeze the GPS is now working indoors, albeit with weak signals (best result I had was 11 Satellites / 7-9 locks - range of 15-31 SNR). On the road it managed 5-7 satellites with locks dropping in and out.
I'm going to hold off on answering because although I have wifi analyzer and gps test pre and post Squeeze that shows it improved......I also have the similar results from 3 weeks ago or so when my gps and wifi were "fine" and then they went "bad".
So something changed for me even before the Squeeze (no, I didn't drop it ) So I'm hesitant to say if mine has been "fixed" temporarily or more. I think that IF this connection is the culprit then we all might find that our reception might be hit or miss over time. Hell, all I did was reboot a few days ago and I got a lock on a few satellites v. none prior to rebooting.

It's just the original technique that is applied to the Prime, that's all this Vulcan Nerve Pinch is.
When looking at the Endomondo walking map on my Rezound, it shows periodic drops at places, as though the GPS lost satellite. I've experienced this since the pre-Global OTAs and ROMs based on them, as well as the Global RUU and ROMs based on it. I'm using the stock battery and stock battery cover.
I don't have this issue with my Verizon Galaxy Nexus and wifey does not have the issue with her Droid 4 using the same walking route.
So the question is whether: a) I have a flaky GPS b) there is some HTC trickery that sleeps the GPS based on some unknown criteria (avail power? Current velocity? Free resources?) Or c) there is some incompatibility between Endomondo and the Rezound's GPS that causes intermittent drops

I found Endomondo to be a little flaky. I personally use Cardio Trainer (I think it is by the same developers). You might check in your settings to see if it has an auto pause and start and see what the setting is.
I haven't noticed any issues. I've used it about 20 times for 1-2 hour walks and it tracks the whole thing. When I've used it for walking in my neighborhood it even shows which side of the street I walked on.
I've manually paused it when I've had to tie my shoe or something and started back up and it worked flawlessly.

Same here, I've used many times and have found the tracking to be solid.
There was a lot of discussion about this back in 2012 - problems with inaccurate tracking in multiple apps with the screen off. People were testing different apps and posting results. I'd search the General forum (sorry, at work don't have time to look up the threads), though it might have been in Q/A, don't remember. We also tested a couple utilities from the market which are supposed to keep GPS running at a high priority when the screen is off. My personal findings were that the tracking problems weren't bad if you were moving at a higher rate of speed (e.g. driving, biking, maybe running), but became wildly inaccurate if tracking when walking or hiking. Haven't tried in a while, not sure if this is still an issue on newer ROMs...

Hello everybody from Xda,
I'm looking for a new phone for my mother and I am really interested to know what the GPS is like. If the gps is any good I will join the Xiaomi army.
Why am I so interested in this?
Well my mother her navigation system just died and, I would like to install the tom tom app on her phone, I've got it currently on my oneplus one without internet and it's great. My mom will also have no data plan with her phone so google maps or anything isnt an option for her
So my question to you guys is, does anybody of you have had any ecperience with the gps.
Thanks in advance XDA,
Deameong
I am curious about the same thing. I use GPS without any Internet or even phone signal (normally on airplane mode to save battery). And I would like to know how reliable it is.
Attached a Screenshot, few Seconds (about 30) after switching GPS on. GPS receptions is really good, from my point of view.

Using google map and waze, locking on me very fast,
Looks good and stable with great reception of the GPS...
Can you say how much time in seconds need to lock satellites?
Thank You
Thanks alot for the advice guys,
Going to order it tonight!
I've just come back from holiday and I used GPS extensively with the offline Co-pilot app. It worked almost flawlessly both in the car and when cycling. I can't begin to tell you how much better it is than older MTK eqiluipped phones. Lock times varied from four seconds to nearly a minute. One thing I noticed is that it was much faster to lock in Co-pilot when I was connected to the internet. Accuracy was great, though I never went into a big city with lots of high rise buildings.
GPS, Wifi and network signal 2-3 times better than on my Note 4.
GPS is sick, in my room after 2-3 sec.

Ill give uadvice gps locking depends onyour connection and area,i use gps in city with locking time vary from 10 -80 sec or more the signal was good but for gps signal its not good so it some time locks slower, this is qqualcomm 400 chipset ,newer version of mediatek might performs better and i have ever try gps with airplane mode one using gps test on aa mountain area and it lock 30 sec or less,the signal came out by it self with no connection so everything depend on your area and your xhipset ,newer chipset performs excellent on gps
I'd like to know more about how the GPS in this phone is faring for you because for me it's an endless horror story. Neither Google Maps nor Endomondo give even acceptable locations and tracking.
And the compass is so bad I wanna puke.
The phone is great in almost every other aspect, but GPS is fairly important for me and I'm starting to regret purchasing this phone. May it be fixed with better ROMs or is it a hardware fault?

I used it yesterday for half an hour in inner city traffic. The phone found the GPS signal in a few seconds with data connection, without it takes a minute or two. Navigation itself was worrisome. Went under a bridge and signal was lost for about 2 minutes. Then Google maps always thought I was going inside buildings or streets next to my actual route. Really weird.

I don't know what you're on about, but GPS Test uses the same API and sensor as any other app. I'm getting the same 5-7 second fix indoors from GPS Test and HERE Maps. Both don't jump around and show my correct position.

Well we use diagnostic tools to know accurately if something is wrong or not, nothing wrong with that. With GPS Status we can know how many sat signal we got, how strong, what is the margin of error, etc.
And i don't have any problem in real life apps and GPS status confirmed that fact.
If you want positive info or help don't start with a negative.

China ROM GPS problem
But with china stable rom, the map apps is using Baidu, and if your GPS location is not available, the device will report your network location (wifi/3G), which is in simplified chinese to your requesting apps, that sucks, however, I can't deny the hardware GPS here in RN2 is the best I ever used.
I tried GPS in the city. High accuracy, pretty fast lock and it worked just fine, no problems. Accuracy is usually 3-5m, 17 satellites in use on average. I'm not exactly sure what kind of problems you're facing. However, I can tell you this. A friend has Meizu M1 Note, the GPS was at first very good. But somehow at some point after updating, the accuracy's became horrible, 80m+ and it kept losing connection, IF it managed to establish one. It's most likely not faulty HW, but a misconfigured gps config.
