[Q] GPS is not working - Acer Iconia A500

ok i was on my way to some place and i was having Wi-Fi connected with both
(My tab and my mobile samsung galaxy S i9000)
and i was in open sky
still my tab wasn't able to get the location and on my tab but i got correctly on my mobile
why is it so?? is everyone is facing the same problem?
is there any fix for it?

How long did you wait? Since it's not assisted GPS it could take as long as 10 minutes to get a lock. There are a few ways of making it assisted, some are here on the dev section and some are available from Market, so if you're planning to use the GPS a lot then you should perhaps take a look.

i waited for 3-5 mins

Most PDA GPS's do not turn on automatically by themselves unless instructed or invoked by a software application. I have not looked carefully at my Jade clone's SIRF's specifications but most GPS under ideal situations can take as little as 42 seconds when warmed up to get four satellites to lock on to. Four satellites are necessary in most sytems are necessary for 3D satellite navigation (satnav or GPS).
What are ideal situations? Glad you asked. Basically, one of the most critical needs for a GPS is accurate time. This is the first item that must be sync'ed by satellites. To use a gross example, let's say your clock is off 60 minutes. In a car that could equate to roughly 60 miles. Satellites need accurate time because when they begin to sync, they will compute what satellites are available to sync with your GPS. Just like the sun, moon and stars are only in the sky at moving intervals of time, only a fixed amount of satellites are overhead at any given time.
Once your GPS begins to sync, ephemeris data (which satellites and the times they are overhead) is transmitted to your GPS. When combined with accurate time, the resolution of where your receiving GPS becomes easier.
The next critical issue is where does your GPS think it is. If the GPS was last turned on at the factory (testing), then it will store that location as its last known position. Guess what? If you're in Paris, France and your GPS was made in Malaysia, your last known position known now as initial positon to the satellites will tell them based upon time to use satellites in the Asian area to compute your satnav position. A GPS without a good initial position will make it difficult for satellites to accurately determine your location which could now takes a minimum of four minutes as long as ten minutes and maybe even hours.
Finally, where is your GPS physically located? In ideal conditions, it is outside with clear sky overhead in a stationary location. It's easier to shoot a sitting duck; a moving target or a GPS on the go complicates all the issues of time, location and signal acquisiton.
To help you, I recommend you download a small cab file that be used in your Today screen. It is aptly called "GPS Toggle". In essence, like a mechanic warming up your car prior to you driving it on a cold day, this plug-in "warms up" your GPS for you prior to needing it.
There is one thing you need to do to help your GPS - it is best for WM to manage it (a recommended feature from Microsoft). Go to the Settings tab, External GPS (why it is called that on my Settings tab is beyond me). Then click through the screens to have WM manage the GPS. On one tab you will asked to choose a Port from which all your programs will access data. You need to use an unused Port. I recommend Port 9 but that is up to you.
The reason for doing this is if WM manages the data, it will keep the GPS on and provide the resolved info to all applications. If the programs managed the GPS, they could selectively turn on and off the GPS and also block each other from using the GPS. You don't want that to happen. That is why MS recommends WM manage the data.
GPS toggle, when installed on your Today screen, will have an ON/OFF switch. When you turn it on, it will on the same line tell you how many satellites it has found and when it has sync'ed with them. When you see that four satellites are in the green (meaning your GPS is found ready for 3D satnav), then you can use satnav program of your choice.
The GPS uses battery power and supposedly is a big drain on smartphones. You want to turn it off and on only as necessary. Hope this helps (it's sticky stuff good info)!

It might be a fake.
Open the Settings tab, go to "System" and look for "Device information". The CPU must be Qualcomm MSM 7225 and the full model name should be Touch 3G T3232. If not, it's a fake.
Thanks digsf.
Checked the phone and it would appear to be legit (just as well as it came direct from Orange UK)
It is frustrating that everyone else seems to be getting the roms to work, but for some reason i can't get them to do so - i must still be doing something wrong....

Cloned HTC Touch 3G
I went through the posts - I guess even I have landed up with a cloned HTC Touch 3G. Wonder what the drawbacks are. Somehow after a lot of tinkering I have been able to get my GPS to work (yes it has a built in GPS antenna) and it's accurate!
I set the hardware to COM 3, baud rate 4800
application to COM 0
In Google maps>options>GPS settings>manual settings (COM0 baud rate 4800)
IT WORKED!!
The WiFi can't be turned on with TouchFlo. Anybody has a solution to that?

[Q] Geotag Issue

Hi all,
I own a Samsung Galaxy S (GT-I9000) and I'm running Android 2.3.4, CyanogenMod-7-Nightly-GalaxyS.
There seems to be a problem with my camera geotagging. I have enabled both Wireless networks and GPS satellites and I have turned on the 'Store Location' feature in camera settings. However, whenever I take pictures, the geotag doesn't seem to work and the pics often come out with 'Unknown location'.
Sometimes it works and sometimes it doesn't, what I've noticed is that, it only works when the GPS is locked on a location, like when I'm running Sygic in the background. When I don't have Sygic running, the pictures always come out with Unknown location.
As far as I know, the camera is supposed to geotag the pics based on two modes, either through wireless network or/and GPS satellite. That means that even if my GPS is turned off, the camera should be able to tag my pics with my network location (even if it's not accurate). However, that's not the case with me, the pics are not geographically tagged at all, despite the fact that the location positioning through wireless network is always turned on.
Has anyone else experienced this problem? I have tried searching for similar problem but I have found no relevant threads with relevant solutions. I hope someone is able to help me with this. Thank you for your time.
AFAIK geotagging has only ever used the gps for location so it will only work when gps is locked.

Hi Mark,
I can't say for sure, I've come across sources saying that both Wireless networks and GPS satellites can be used for geotagging, but the former often gives inaccurate tags. I have tried searching for a definite answer from an official source or something but couldn't find any.
That aside, I usually have my GPS satellite turned on anyway, but the pics still come out untagged. Upon launching the camera app, do I have to wait for the GPS to get a lock first before snapping the pic? I have tried waiting, but the GPS gives no indication whatsoever that it's even trying to get a lock.
If I have to wait like a minute or two before taking a pic before the pic is able to be tagged, I think that's pretty ridiculous cz seriously, who launches the camera app and leave it idle for 2 minutes before taking a pic right?

This is how I'm doing it.
When I cannot get a lock on the gps, I turn on the 3G data, and open gmaps.
After I get a relative position through my network antenna, I leave gmaps (not close it!!!) and switch to camera.
Before I used open street maps, and sometimes it didn't require the 3G connection, but now I'm just doing the gmaps workaround.
Afterwards it's picasa, and if I got a geotag position on the first picture, I just use that location for the rest of the album
Hi Cristi,
That's pretty much similar as leaving Sygic running in the background like I've mentioned. That's more like a workaround and not a solution. Besides, running Sygic or any other navigation app will kill the battery quite quickly. I'm trying to look for a permanent solution or at least detect the source of the problem to begin with.
You must have a fix, since you don't know where you are before the fix...
With GPS the first fix can be quite long (cold start) since you have first to downloads the ephemerides. After that if the GPS is well initialised it will reused the previous downloaded ephemerides (hot start) so the fix will come sooner...
With assisted GPS, you can download the ephemerides from the network rather than the satellites, so the first fix is normally quite fast (a few seconds). That's sufficient to tag pics (on many devices it's working quite well).
However if the A-GPS is mis-configured or if the reception is bad (not many satellites - cloudy weather - under a bridge or inside a building) then fix will take longer
So the first thing is to configure correctly the GPS (verify that it doesn't restart always using cold start and, eventually, enable assisted GPS to have a fast 1st fix).
If all is configured correctly, it should improve the time needed to obtain the 1st fix.
However if you have a bad GPS on your Galaxy S, your not lucky !
You can try somel of the many GPS fixes you can find in these forums. For some people it seems to work (but not for everyone...).
You can also try to convince your support to exchange your SGS. If you're lucky you will obtain a good one.
Hi Herbert,
Thanks for the suggestions on fixing the bad GPS, I know a lot of people have been saying that the GPS on Samsung Galaxy S is a bit faulty.
I understand that the GPS needs some time to get a lock on a position, but what I'm more concerned about is the fact that the GPS icon shows no indication whatsoever that it's trying to get a lock upon launching the camera app. So, how long must I wait? 10secs? 20secs? Anything more than that is a bit pointless I think.
Another thing is the wireless networks tagging, the fact that the camera is unable to tag the pics based on the network location puzzles me. Anyway, for the time being, I'm just going to assume that my current telco doesn't support network positioning. I'll try it with a different telco and see how it goes.
I installed Compass from App Market...when the gps has already locked a position that is when I start to use the geotagging.
Hi Darl,
I am using GPS Assist to temporarily workaround this problem, I run GPS Assist before launching the camera app. The GPS Assist locks on a position quite quickly, it usually takes around 5seconds or so, provided I'm in an open area that is.
However, I'm still looking for a permanent solution.

AGPS PATCH FOR ICONIA USERS (Works on Galaxy Tab 10.1!)

So I've had issues with my GPS not locking and constantly searching for a lock. I've always only managed to get about the most 4 sats but it would take forever to lock! When I had my Acer Iconia A500 I found this patch that immidietely fixed my locking issue and gained 11 sats which locked on within seconds! I have the Galaxy Tab 10.1 16gb Wifi GT-P7510 and I can confirm that this works on our Tab. (See attached images)
( I downloaded the GPS.config if curious as to which one worked for me)
Here is the linik to the OP:http://forum.xda-developers.com/showthread.php?t=1267899
Hope this works for you guys as it did for me Though it says For Iconia Users it does work for Galaxy tab as well.
Steps I did:
-Downloaded Gps.config only build
-Extracted all
-Went into extracted folder and under system/etc/ copy gps.config
-In etc folder, replaced current gps.config with the copied one and reboot.
-After reboot I turned on GPS and opened GPS Status app and watched the sats pop up and lock
Edit: I used GPS Status app in market to view sats
Never had any problem with GPS on my tab, even inside the house. Coming from a Samsung Captivate, I'd be very wary of any AGPS 'patch' or work arounds. Most of them are snake oils. They will sometimes work for you but none will last over a week.
If you have problems with GPS like you said, exchange for a different unit is the only fix for a Samsung product.
If you are having GPS problems I would probably return it. The GPS on my Tab is probably the best mobile device GPS I've ever had. I could be in my living room, and if I leave Google Maps open for a minute I get a lock with a 5 meter accuracy.
I just used Co-Pilot to navigate a trip from Louisiana to TX. GPS locked while I was still in the multi-story concrete car rental garage. It never missed a beat on the four hour trip. The GPS on the G-Tab performs better than my SGS2.
I'll try this out for a week and see how it goes. Yeah I heard that SGT had really fast gps lock but never saw that when I first tried navigation. Only now after trying out this patch I can see how quick it is. Hopefully it stays like this.I can always exchange it if it doesn't. I'm still within my 90 days. Or if a better tab comes along within that span would be nice to.
Im thinking about buying a GT for my wife, can the GPS be used offline if I download maps? Im thinking about the wifi version...

Maps will provide you with the directions. Navigation will not work if gps is offline. Maps will work fine offline. It will still give you the detailed list/maps like in navigation just not the turn by turn.
my gps only works on my stock TW rooted nandroid... if i flash any other ROM to my gtab the gps wont lock... so strange...

Get Co-Pilot. The maps reside locally and it's not dependent on a wireless connection for navigation. You can also cache routes through Google Maps but it's not a perfect solution and you need to connect again to make any major changes to your route.

I've had issues with locks even when it wasn't rooted. But since I did this patch I've had zero issues. I can easily get 11 sats to lock on vs standerd 4 sats. This patch is better then the original imho.
thanks
good app

Hi Guys,
Lucky me, I've got 2 devices as gift from 2 different persons on an occasion. One being Tab 7.7" and the other being Tab 7 Plus
Obviously I love the 7.7 for the brilliant screen. I thought I will use one of the 2 devices in my car just for navigation but just to my shock I've found that the GPS lock is taking longer when compared to other devices (Okay, My wife has a iPad and an iPhone) ....
As far as difference in time to lock in to the satillites like the Tab 7.7 sometime take more than 5 mins (Once it took close to 10 mins) even while I am in a road with clear sky but the Tab 7+ is a bit faster may be 2 - 5 mins for the same which is still longer than acceptable.
Edit: SIM card on.
Car Navigation Application : Sygic (Singapore & Malaysia)
This application is a charm and it work beautifully on my HTC Desire HD (<5 sec for lock) and iPhone 4 (2 - 5 secs) even on a cold start. So it surely is not an issue with the version of the app in android but the problem with the device.
I am still very happy with the tab 7.7 after all what more can I ask for something that I've got for free but just curious about others experience as it could be a HW issue for me.
Let Us all share our GPS experience here wrt issues and accuracy (both good and bad) with which we can create an repository of information for others to refer with.
I have noticed that my GPS won't lock on unless I have a sim card or when I was thetering to my Samsung galaxy s phone. Also noticed that it is not really accurate its off by quite a bit. Any suggestions on how to get it to be as accurate as possible.
Sent from my GT-P6800 using xda premium
I got the same problem, on my p1000 i can get a lock for 2-5 secs using copilot, i used the same on my 7.7 and it takes forever to lock..
Another this, using this as a gps device might not be a good idea, it could cause burn in issues that AMOLEDS suffers from.
Just my two cents
when i bought my 7.7 tab it has no sim in it for about a week but the GPS locks very quickly (i precacached google maps and used it as GPS device when driving), initial lock takes about <1min while succeding GPS locks <10secs, as far as the specs indicate it has the same GLONASS GPS capability as the GNote
On android, I'm pretty sure GPS is useless without a data connection. My 7.7 takes a few seconds to lock on at the most, using a sim card. Even locks on inside buildings. When I took the simcard out once, it then took forever to lock on..
Sent from my GT-P6800 using xda premium
I can confirm that my 7.7 takes only a few seconds to lock on with sim inside. Haven't tried without it yet.
Just tried mine for the first time. Enabled satellite + Wifi location tracking. Locked on within a few seconds.
I am in Muscat, Oman and Wifi isn't as eponymous as in US cities.
Edit: Just to be clear, I have a sim card with an active data plan in the device.
I got problem, on my p1000 i can get a lock for 5-10 secs using copilot, i used the same on my 7.7 and it takes forever to lock..
Guess it suffer the same problem as asus transformer prime. because of the metalic back it cause the GPS to suffer.
can anyone try GPS track program? see how many GPS satellites being lock ?
Mine locked within 10 sec for the first time while riding in a cab (it was down to 5m accuracy)
How can we increase accuracy?

When I used my GPS in Germany and France my data roaming was DISABLED, so I guess it only used GPS to lock on within the 10 seconds that it did so?
I have noticed that the GPS only works if you have some form of data on the tab ( either sim or wifi ) if not the GPS will not lock on and it says "data connection lost", why would this be? Is this normal or a bug?

The tab's GPS unit probably requires AGPS data, which is downloaded from the internet. Some GPS units don't require the data but I assume this one does.

Ahhh OK, thanks for the info. Actually then how do the wifi only version work? Guessing by what you mentioned it does not require AGPS
Sent from my GT-P6800 using xda premium
The Wifi only version would use AGPS as well. Basically AGPS is assisted GPS. It uses cell towers (for 3g models) and/ or wifi hot spots to provide location data, hence assisting the GPS unit in your phone or tablet. Try removing your sim from your phone and switching off wifi, the same thing will happen. It will take awhile to lock.
I have a galaxy S, which is notorious for poor GPS reception. I use a bluetooth GPS unit (check out apps in the market) with my phone, and it works a treat.
Mine 2-5 seconds with SIM and using fasterfix for my region (China) -- accuracy is TIGHT (5m)

[Q] lenovo a3000-h, GPS not working

Hi
I've got my tab about 4 months now, haven't rooted it or anything else, although I'm considering it, as it doesn't have call function.
I noticed last weekend that my GPS doesn't work - I've checked that my location settings and a-gps are enabled.
I've used 3 GPS status apps and all of them show 0 reception.
If I recall correctly, the GPS used to work, as I'm passionate about GPS and have spent thousands of hours on GPS and mapping projects in the past.
My question is:
Should I
1) reset my tab to factory settings and see if GPS works?
2) take it back for warranty repair?
3) try to root my tab and see if it works (and also do the call function ROM)?
With regard to 3) above, will I be able to root my tab as I'm using Ubuntu laptop?
Thanks
