8 GPS problems, advice. & questions (xtra, agps cache, epo, hardware, - Android Apps and Games

1) It could actually be hardware.
On my i9000 the rubber connector between the case and the board had failed. Trying to solder a spring onto it appeared to burn out the chip completely.
Try another device in the same place. Looking at my Nexus I see a spring connection to the back case for some kind of ariel. Not sure if it's for the GPS. Q: Can we connect an external GPS antenna to help test this variable? Most people have tested this by breaking the connection between the mainboard and the antenna. It's a slow process unfortunately.
i9000 hardware GPS problem:
http://forum.xda-developers.com/showthread.php?t=1697217
Nexus S 4G CDMA (i9020a) link to same problem
Page 5 has links to internal diagrams and mention of NFC antenna getting magnetised affecting compass.
2) No GPS in the sky (or not enough of them). Go as far North as Northern Norway or Alaska and you can have troubles.
Try another device in the same area. Cloud cover will degrade the signal, so will trees. Q: Better way to test without standing out in the rain?
3) AGPS cache has crap in it.
Do a AGPS reset.
4) AGPS server connectivity. Could be a GPRS problem. Could be WiFi problem. Could be at the server. Check what server you're using to see if you can contact it from the phone. Q: Is ping a good way to check?
5) EPO server fails. Perhaps md5sum is broken:
http://forum.xda-developers.com/showthread.php?t=1975500
YGPS and the engineering menu on mtk65** phones is very useful. EPO downloads a map of where satelites are expected to be so the GPS then know exactly what to expect. The list is updated once per day. Q: I'm only aware of this on Mediatek phones?
6) GPS works better when moving.
If you have
### ROOTED SAMSUNG GT-I9100/GT-I9100T/GT-I9100G/SGH-I777 or GALAXY NEXUS DEVICE REQUIRED ###
Try: GPS Control SiRF
^ We need a better version of this app to work with more phones.
7) Some radios are better than others. This is where it gets difficult. Is there a single phone out there with open source GPS drivers? (not geeksphone afaik). The GPS code AFAIK is in the modem image, totally closed. Perhaps there's a way to generate a GPS signal to test with?
- If the worse comes to the worst you can always buy a Bluetooth GPS module to lug around and use that. I didn't have success with Cyanogenmod's built in external GPS in the settings so I used "Bluetooth GPS" on one phone and "Blue GPS" on another.
- I've heard GPS doctor (aids?) is a good app but expensive so not much use for diagnosing different phones all day. This XTRA download thing I don't fully understand.
- finally, do you know of a recent small screen phone with a good & reliable GPS?
update:
I will update this post as I find info along the way.
Basically what appears to be a big source of difficulty diagnosing errors is that there is no way to isolate the ariel as a problem. The Android API doesn't include access that low level.
from:
http://stackoverflow.com/questions/4250434/how-can-i-get-the-gps-raw-data-satellites-pseudo-range
Code:
Satellites pseudo-ranges are not available in the official API, neither through the GpsStatus.Listener nor the GpsStatus.NMEAListener interfaces.
The only available info available in the GpsSatellite class are:
PRN
azimuth
elevation
C/N0
a "usedInFix" boolean.
The Android source code asks just those fields from the native code, so no hope to get it from any other Java API.
The best way for you to get this data anyway (which is not suitable for a Market-able application) would be to explore Android source code, and either find a native hook to get the data at low level and access through JNI, or recompile the full OS modifying the API to your needs (you also need to find the relevant native code for that).
Finally, if you can get the chipset to send you GRS NMEA sentences (you would get them through the standard NMEAListener interface, the difficulty is configuring the chipset to send them) you can then compute the pseudo-ranges (those sentences contain satellites' residuals)
Good luck and let me know if you try any of these ideas!
update 2:
The connector on phona mainboards (assuming you have one) is "UFL". The connector on some GPS external ariels is MMCX. The bigger connectors are SMA. If you want to connect a external GPS antenna for testing without soldering you probably need a UFL to MMCX pigtail.
Plugging in UFL connected external ariels may help with diag for the various radios.
I have only 2 satelites seen on mine. I've bent the print connector up to touch the ariel a little harder but still it's a bad connection (presumably). I am thinking of ordering:
http://www.hwkitchen.com/products/mini-gps-antenna-embedded-ufl/
just to test it and confirm.
I'm guessing a magnetized NFC ariel wouldn't cause this. Removing the back (which has the NFC Ariel is) hasn't helped anyway even though the magnetometer does respond to taking the back off.
"file create fail" is what I get in trying to run the antenna test with LBSTestMode.
This hardware fix doesn't seem to be intended for the 4G but I tried it anyway:

Is there a better way to test? I'd like to see the raw data that the GPS is getting from satellites too see how it is caluculating the position but I don't think that's possible.

To help you with testing Droid VNC Server can be useful - you can then connect to your phone when it's outside over wifi while you sit in the warm. But be careful because if your wifi connection breaks I notice it then starts listening on your 3G/4G connection, open to the world.
Likewise adb screen monitor over wifi is a security risk too.
Generally the first thing to try is to clear the agps cache using gps status and then redownload it and leave it with a view of the clear sky for 20mins.

The ultimate Question tracking your XDAII around the world

After FINALY finding a working way to get TomTom nav 2 working on my XDA2
(with the Lead from the XDA.1)
I was Driveing arround and Thourt to myself...
Is there a way to Transmit my GPS Map refrence point Via GPRS
Back to my home PC where the Map refrence can be Linked
to an on screen map at home?
Much the same way the GPS plotting is linked to TomTom Maps
for navigateing.
been thinking about this more today.
shurely the data from the GPS isnt too big,
If there was a way to relay the data onto a IP address (home pc)
and have a Map program like TomToms understand that data
in the same way TomTom maps do, then you (or ya missus)
could track your position.
ok mebe not in real time, but im not a Tech so i have no idea how much
Data is involved in GPS plotting but a 5 second delay wouldnt be bad would it?
this is kinda the way GPS tracking works in tracking stolen cars i guess
but now we have GPS on our lovley XDA2's we to can transmit that data
Via GPRS couldnt we ?
I think you can have a look at this solution:
http://www.geocities.com/gps2sms/
It's using SMS, GPS to track your current coordinate. It's free. You could tailor it if you want.
Sorry I forgot to mention that currently it works with Nokia or Siemens phone with a laptop. The Nokia phones are there to act as the modem.
It doesn't work with XDA but I was just thinking about thse app's idea of using the phone to send the current coordinate. the O2 can replace the laptop and send using SMS or GPRS to a central location (your server) and updates it real time
I am doing a program for the XDA II that will send your GPS location back to a given number i will post a few screen shots if you like.
You will be able to select any com port that you like it works at the moment with All TOMTOM devices.
Paul J
DA Systems & their Nexus/NX product for the XDA1 & 2
I have done simillar using area codes and also with fixed GPRS/GPS units.
You need to send Lat/Long & ID to specific IP/port via GPRS, then add that to a database, which can be parsed by a mapping program such as MapPoint.
Cheaper than SMS

This is the Com port Bit and the GPS bit
I will post more later
Wireless Delivered (www.talecom.net) has been doing this for over a year using the XDA I!
It even has an real-time map online where you can go and look at where your XDA is! 8)
Richard
Ah! But has it being working for over a year?
Sorry - couldn't resist
intresting stuff
but is there a simple app that i can hunt the net for ?
no thats why i am doing one
I work for a company that uses tracking (GPS) phones and we have looked for a system for the ipaq and the xda that we could use in our software.
I use http://www.mapamobile.co.uknot very accurate though
but can u still use your gps?
if I understand you correctly, if your code is running, my wife can
see where I am from home, but I can't run my moving map
what we really need is to "install" a new COM5 etc port,
so that TomTom reads COM5, our program reads COM4
where the real GPS is installed, and send it over SMS/GPRS.
Scheme
GPS -> COM4 -> sent to home
-> also copied to COM5 -> local GPS(tomtom) display
I'm not sure how to setup a "virtual COM" on PPC. It is pretty
easy to implement on UNIX (virtual tty).
Ideally, someone should write a "dblCOM" utility.
it takes COM4 and copies its output to COM5 and COM6 ...
it takes input from either COM5/6 and copies back to COM4 ...
(com# are configurable of course)
this way we can run TWO DIFFERENT GPS SOFTWARES at the same
time. this is far more useful than you might think... one could be
a visual display of your speed/acceleration/etc, the other moving map.
serial+gps+camera+voice record+gprs in one fast computer box
is a mighty powerful machine.
think of connecting it to the engine monitor in the car and having
a complete monitor, not to mention a blackbox, for every car
on the planet ... you can even pinpoint drunk driving in real time
using special intuitive software ... and the government will probably
make it mandatory in every car before 2020 ... yak.
Did you know that the first matrix was a perfect human world?
It was a disaster...
Get the TomTom SDK & you can do most/all of the above.
The SDK has the ability to make GPS positional data available to another program as well as TomTom. You then just need to create a vehicle for sending the data back to a remote location.
The real question should be - "Do you really want your wife tracking where you are?" 8)
I have been doing this for some time now:
1. Use Oziexplorer for navigation on XDA1 / XDA 2
2. Use Net GPS to send GPS data to a web server through GPRS (Or GSM) (you can use it alone or with Oziexplorer on the XDA)
3. Use Oziexplorer for PC on remote PC, connected to the webserver through Internet
http://www.oziexplorer.com

I like to share this URL of not too dissimilar project by one person which I happened to stumble in the newsgroup:

*** Tracking your XDA using GPS ***
Hey you guys
I cant believe that your trying to reinvent the wheel
Have you not heard of Co Pilot Live 4
It does exactly what you want, despite being a better SatNav Program anyway IMHO having street names as well as road numbers read out verbally it also allows you to log on to their website and see EXACTLY where you are and even your direction of travel from your home PC. AND it even allows you to communicate by sending text messages to the PPC with custom design responses.
Imagine the wife can now ask you
What time will you be home from work? [6pm] [7pm] [8pm] [9pm]
Can you pick up little johnny from the School Play? [YES] [NO]
Oh what Joy!!!!

GPS bluetooth Dongle

After trying every rom, modem and so on and so on... i got damn sick of it and went to the store and grabbed myself an Blue-GPS-S3 with SIRSTAR III supporting 20 channels...
You know.. the difference of gps quality is shocking. 12 sattelites at good performance and unbelievably stable. Navigation for four hours straight and not ONE mistake or recalculating required... amazing.
My advise is... get one for those 20 euros and stop wasting your time on trying to get your gps to work.. cause on top of this.. using bluetooth uses less battery then using internal gps asfar i noticed.
Hope this helps someone making this step, you do lose being able to see gps status in navigations progs but Sygic Aura + CoPilot worked flawless, il make an list of working apps
[update]
Okay drove over 800km in two days and what a trip and for once.... yes for once i didnt feel stressed about my galaxy abandoning me somewhere, altought i must admit my gps has not the greatest name and reputation it did its work excellent no matter where i came.
Some info.
APPS:
Bluetooth GPS mouse = GREAT. worked flawless with my external GPS
Bluetooth GPS Provider i didnt have a chance to test with yet, i will soon and report about it. One thing i must add, it remembers your dongle/mouse/external gps and with its simple ugly widget you can quickly turn it on and let it connect with the dongle. unlike gps mouse you gotta open it and turn it on and choose dongle.
NAVIGATION:
Sygic Aura = working great, it was however required to switch GPS on first and wait 15-30 sec to make sure it had atleast 1 signal before starting aura navigation, else it wouldnt pick up the signal
CoPilot = just awesome, worked directly wether i loaded gps mouse after or before.
Google Navigation = no idea, I assume it works as google maps works to with it.
Waze = no idea, I still have to try it but as waze worked most flawless on internal gps i assume no problems at all with external gps
KNOWN PROBLEMS
Programs do not see the GPS status.. signal, altitude etc etc. weirdly enough the navigations work flawless and they do not complain about having no signal either.
SHOPS:
My shop does only send in the netherlands, however... mine is a Qtrek Blue GPS-S3 with a SIRFSTARIII chip. Basicly ANY bluetooth gps mouse works with your phone.
could you please give me a link to where you bought the item?
I've looked, but couldn't find cheap ones..
i got a co-pilot bluetooth gps unit £8 from amazon and its great. a bit tricky to set up but well worth it.
re
800km in two days.. man am i exausted but what the heck.. that thing works briljant! il update first post with info
Cheers. This is great to know. Too bad Amazon UK has horrible bluetooth GPS seller reputation. I will have to find one on ebay instead.
I use the Nokia LD-3W gps module and it is fantastic. Easy to set up (takes seconds). I use the bluetooth mouse with "bluetooth GPS provider" which is a free download from the market. Very accurate with google maps, copilot etc.

Where did you buy this from? Amazon UK?
is it really helpful to use usb bluttooth
re
Im using bluetooth gps now as its free and works great however it said that Sygic Aura wouldnt work due it doesnt support mock locations... bummer as its the best gps out there. however the Bluetooth gps mouse app does work with it but then again i noticed that application turns on internal gps... not sure wether it fakes that or actually turns on internal gps... guess only one way to find out. wait for a next trip

[Q] Snapdragon S4 unlock GLONASS ?

Hi, i am new here thefore i cant post in "One S Android Development"
I KNOW that (HTC one s)Qualcomm Snapdragon S4 has support for GLONASS. can it be unlock ?
anyone known what soundchip it got onboard also ?
Appreciate the help.
Are you sure it needs unlocking? Mine said on the box "Supports GPS/GLONASS". Not that I have any idea how to check.
Sent from my HTC One S using XDA
Download GPS test from the market.
Fire it up and see if you log any satellites numbered 65 to 88.

My Htc one s, havnt arrive yet, i still waiting, i think it would come next week, then i can do the gps testing. It would be nice to hav a good gps.
I am using Samsung galaxy s1 and its worthless in sweden..
Btw i hope Snapdragon s4 get Wolfson audio chips
My HOS IS showing satelites number 69 and 71... are those GLONASS sats
Out of 15 satellites that I could see, 6 were #65 or over. Looks like GLONASS is working fine.
Edit: Just to clarify, I'm in Japan, but my phone came from the UK so is the European model (No One S for the poor Japanese, lol)
So it works completely transparently to the user and does not need special software or adjustments, it will just work by "supplementing" the accuracy reported through the GPS interface and therefore also every navigation software etc. will automatically benefit from it?
That is kinda cool if its the case.
This is going to be GREAT for once i can use "GPS" correctly in sweden, anyone knowns more about the Sound chips onboard the S4 ?

Yup, looks like it. There is no separate setting to "Enable GPS" / "Enable GLONASS". Although rather than being transparent to the user, it is more like hidden from the user. I guess the average user neither knows nor cares about GLONASS, as long as the thing shows them where they are on the map.
I do not get satellites > 28, but total 22 visible and 14 in use.
Don't know if GPS or GLONASS - but 22 are a lot
My HOS consistently sees ~17-21 even when indoors although while indoors I get no GPS lock even though GPS Test says that it uses ~5 satelites. But once I take it to a window it gets a good lock immediatly.
My old Desire and my TF101 only sees ~4-5 when doing the same test. So it seems that the HOS really are using GLONASS too.
Yes they do. With GPS only I never had a situation where I could "see" more than 6-8 sats at once with a mobile and not all of them had a fix/lock because the signal was too weak (only once supposedly had 9, reported by an Audi in-car satnav with dedicated external antenna, but I am not sure if that was fixed sats or just the visible ones). I think as of now I think there are less than 30 functional sats in orbit globally and the GPS architecture hovers around an amount of 32-36 sats maximum (with higher coverage of landmasses and lower coverage on the oceans).
Also, GLONASS will be very beneficial to anyone in the upper northern hemispere, and lower southern hemispheres as the system is of course globally active, but due to sat orbit inclination and distance (orbit heigth) it allows a better coverage of the regions closer to the polar regions, while GPS seem to be more designed to cover the "middle ground" and also have a lower orbit.
And when the US went to war in the middle east, I think I have read about some of the satellites being repositioned to give a better signal feed to the troops and equipment in that area, therefore automatically neglecting the rest of the world a little bit.
This is a really good feature I did not even read about in the reviews prior to purchasing. I pity the folks with the One X who don't have that... It will double satnav usability and accuracy even in less than optimal conditions (cities with high buildings covering satellite line of sight etc.)

Gps fix for mtk 6577 and other androids(root must)

Hi friends.
I know that
Many of us mtk 6577 based phones users are having issues on using
Gps issues
Like not locking on satellites or gps takes forever to get a lock
Try this and u will be amazed.
Ju st found a great fix for gps Instant lock in 10 seconds Who are facing gps problems Just do as following and u will be amazed how fast u get locks on ur gps U have to be rooted must.. U have to be rooted must..
1.transfer the given gps.conf to ur system/etc folder backup old one
2.change permissions like this rw-r-r and restart.
3.install gps status from market. 4.now open gps status.
5.open setting of gps status and tap on tools/manage agps stats tools/manage agps stats And then tap on reset.
Repeat step 4 and tap on download
Now go to open space or near open window and it will start to pickup satellites in 20-30 seconds U will
U will see dramatic improvement in satellite picking up speed.
Before doing this i hardly locked to 2-3 satellites. After this i can get lock inside my house near window. near window. The following is indoor satellite lock snap

not able to lock on to the GPS according to the supplier he said it works there but i could not resolve this issue.
can i try your method is it save to do on this machine.
please guide me on how can i transfer the file & change the permission according to your info.

Wow, the picture says you're moving at 36 mph 750 meters UNDER sea level: either you live inside a submarine, or MTK GPS is pretty unreliable isn't it?:laugh:
Btw, I tried the procedure on a firend's phone and it worked almost good, it didn't fix at all before but now even if it fixes, loses GPS signal very often, requiring 3 to 15 minutes to have GPS back!
I also tried Engineer functions with test and reset operations, but GPS is always unreliable (1 hour trrip it lost GPS for more than half an hour, making navigation imposssible!)
I think the GPS hardware is really unstable and/or buggy. Any idea?
Yeah the hardware is really crap
And i was undersea and was sleeping there...

What's the point of having fast lock when precision suck?

Bumping accuracy threshold from zero to 3000 likely report hyper sonic speed way off sea level
My MTK Phone
Same frustrating GPS issues here.
Hi my MTK phone from china has a file under something like gps-profiles-config. should I delete this and replace it with yours? or do i just paste it along with that one?
Engineer code MKT6577 phone
Hi I found a code for the engineer mode.
Here you can also change the settings for the GPS and test it.
Looks like my GPS is not working because it doesn't show any satelites.
The code is *#*#3646633#*#*
You have to use the phone dialer.
Hope this wil help to find a sollution for the GPS problem.

Hi guys
I was having issues and tried multiple solutions including the one posted here in this forum. I believe it helped me the most, because it resurrected a non working GPS. However it was still taking 3-5 minutes to get a lock. I came across the following video post and after applying it the lock time is sub one minute... which is great. I thought I'd share it here
Basically the answer is to delete/ rename the mtkgps.dat file from data/misc and then recreate it with the mobile uncle tools .apk which can be got from the play store.
The youtube video makes it easy.

Of course your phone needs to be rooted as well. I can take no responsibility for what happens if you try it. But it's worked for me.
Also as said before, This only worked in conjunction with the fix discussed here in this forum.
Hi,
I tried to use your solution in the video, my phone did not open the gps fix app but in the end I found a gps signal thx!

The Real GPS Fix
To all members with GPS not getting a fix on the satellites with the V1277 (6577) in a reasonable time I have the answer and it does not require anything but a screw driver and cleaning fluid.
No rooting is required or messing about with the gps config.
Firstly remove the back cover.
There are 4 screws holding the housing remove them and unclip the rear housing .
Take anti static precautions i.e ground yourself.
Use alcohol or another circuit board cleaner and clean all the contacts on both the main body of the phone and housing, Job done.
Before I did this I could not even get a fix on the gps satellites outside , I can get a fix in the living room.
I think the problem lies with the production environment of these phone not being as clean as the major manufacturers dirt and oxides in the air, I use to work as a debug engineer on mobile phones at Motorola, well at least its came in handy.
Probably a fix for most china based phones
This method does not work on my device. I start wondering if there a gps antenna in my phone, maybe they cut cost and remove the antenna :laugh:

Flaky GPS

Hi guys
I recently bought a "Hizpo" mtcd PX3 2GB head unit. Generally it's working well except that gps sometimes gets Fix quickly, sometimes slowly and sometimes it never gets there at all.
Weirdly, sometimes it sees any 8 satellites but still can't get a fix.
I see this in malaysk and stock roms and had resorted to using a Bluetooth gps for a while.
I have swapped the antenna for a new one (magnetic type) - it is maybe a little better but still not reliable.
I've measured 2.7v on the gps socket - seems a little low when the antennas nominally need 3 or 3.2 - maybe they're not being amplified properly?
I've read that some people have had to open and resolder the gps connector on to the board when it has a poor connection - I'm reluctant to do this but may need to.
Any suggestions for solving this would be appreciated - it's driving me a bit nuts.
My only thoughts right now are to shift the antenna above the dash and see if that solves it - or open up the unit and resolder the connector.
Try using "Faster GPS" ( https://apkpure.com/fastergps/org.fastergps )
With this app my GPS has improved a lot !!
Once the app is launched, you must specify your continent and your country.
I hope this can help you

Hi guys
I recently bought a "Hizpo" mtcd PX3 2GB head unit. Generally it's working well except that gps sometimes gets Fix quickly, sometimes slowly and sometimes it never gets there at all.
Weirdly, sometimes it sees any 8 satellites but still can't get a fix.
I see this in malaysk and stock roms and had resorted to using a Bluetooth gps for a while.
I have swapped the antenna for a new one (magnetic type) - it is maybe a little better but still not reliable.
I've measured 2.7v on the gps socket - seems a little low when the antennas nominally need 3 or 3.2 - maybe they're not being amplified properly?

Thanks - I've just installed TopNTP which seems to do much the same thing - I'll see how it goes.
How it is now?
I often have problem like that- my px5 unit see the satellites but I takes couple minutes to get fix, why it's happen like that?

I think it's the system's fault. No or bad gps.conf file. Having an internet connection and a properly configured file, the data necessary to start determining the position is retrieved much faster. The program must download the so-called data from GPS satellites "ephemeris" or "ephemeris". They contain information about the orbits, times and other data that accurately determine the position of the satellites. If you have correctly configured gps.conf file, you download these data online. On the phone without internet, the "fix" catches about 50 seconds. with internet enabled, grabs after 8 seconds. The GPS Status application allows you to force the data to be downloaded manually, so-called A-GPS data. But it would be best to properly configure the gps.conf file and place it in the / etc directory. I just do not know how to save data in the system directory / etc without root? Maybe someone will tell me how to do it on not rooted device.
