[Q] GPS Offset Issue - Droid Incredible Q&A, Help & Troubleshooting

I've used the Google navigation for a long time, and never got a problem. CM7 stable was installed, and works well for a month. I'm in NY state.
However, yesterday, I found GPS deviated northward for about 100 feet,and not always, sometimes could get right.
When I drove west to east, the screen showed me I was driving across buildings...
I can barely drive without navigation, Could somebody help me?
I'm not a native English Speaker, so sorry for my poor language.
Thank you

anybody met that?

Is this a constant issue with it showing your location incorrectly? You could try a different radio as that is what's communicating with the GPS.

Thank you
Could you recommend one?

I'm personally using the leaked evo radio (4.08). I would recommend www.dougpiston.com, go to the radios section and try some out. I usually test radios by looking at the signal strength in settings>about phone (lower dBm means stronger signal), the speed test app and GPS test is a good one too.

I've had that happen to me before, I restarted the phone and it never happened again.
Sent from my Incredible using XDA App

I had that happen to me with one of the CM7 nightly builds. I noticed it was fixed after I flashed 10.05.06 radio and a newer nightly.

God, I've tried the newest radio,but still have the problem

Weak GPS!?

anyone having a weak gps issue? i am. goog maps or navigate or telenav can't track me accurately. ot can find a location but it sucks finding me and navigating. ive been in every major city from san diego to ny to new orleans atlanta dallas etc... military and on vacation and no matter where i go the gps sucks. it does however have a crack on the top left corner over the front camera if it matters. i have the latest prl update and all

I think there is an issue if you leave your phone on for a certain number of days, the GPS stops working accurately. Try rebooting your phone
ive tried that. it still sucks.

You might want to exchange it. I use mine in L.A. and Orange County and it is pinpoint accurate. I was actually surprised how well it was working. It was exactly right on when I had to take an offramp to another freeway or during surface street driving. I am using Telenav
Sent from my SPH-D710 using xda premium
I agree exchange it. Our gps on telenav here in Houston works perfectly, very quick and accurate, beating google maps every time.
download gps status and toolbox it will fix your issues. If not then return the phone is your best bet..
ok, let me try that. i drove through Houston last week and my navigation thought i was onbthe road but i was on the katy toll

Download this, reset your GPS, if it still wont work I'd take the phone in for a replacement. My GPS wouldn't lock on last night, I had to use this to get it to work.
I had the issue above but once i reset the phone it seems to be very quick in pinpointing my location
working ok now. lets see when i get into san diego tonight service sucks here in pensacola

Unless I'm missing something, there's a thread hiding in the Dev section that's supposed to fix GPS troubles. I don't know if it's a different issue from what you're having, but thought I'd put that out there.
I tried searching for it. Can't find it in dev.
My gps sucks! It's useless
I tried the apps and resetting gps cache. Still nothing

The GPS issue has been "fixed". Most people's A-GPS got updated and they're getting locks again.

I have, speedtest.net isn't working.... but maps seems to lock on.... not quite sure what's going on.... maybe it's the speedtest app??? idk...
edit: just tried speedtest.net on my i..... err.... "other" phone.... and speedtest.net isn't finding a location server either.... so it's not my nexus.... maybe the GPS is working after all...
The "fix" does nothing for me and I've tried GPS test GPS status and faster fix. Have reset the a GPS setting and still nothing. The GPS icon doesn't flash or fill in it just stays empty until after about 30 seconds then tells me unable to get a location

Google fixed A-GPS data that they were serving phones. People are now reporting that they're able to get locks again. Mine's been a bit shaky still, but I do lock eventually.
Try another rom. I was using cm10 alpha and was starting to blame my gnex. But then I tried jelly bean stock, liquid ics, and some other rom. And GPS started to work like a champ. Instant GPS lock. And while I was on edge too! Try another rom.

i cant get NAVIGATION app to lock at all -- on the OTA deodexed JB rom from the forums -- did full data wipe re-install still cant get a lock
Try liquid ics. I'm using he GSM nexus with T-mobile. This would help determine if its a software issue or hardware. Yesterday I put liquid ics and stock jb.to the test by driving around my city and they both locked on and responded very fast.

Last week, some bad A-GPS data got pushed out to Nexus devices, and people were unable to get a GPS lock for several days.
I had no issues when everyone was reporting GPS issues but today my GNex took at least 3-4 minutes to lock onto GPS. I'm not confident it isn't ROM issue, I'd have to run some other tests to isolate it, but there is definitely something weird going on with GNex's GPS.

GPS fix? AOKP maybe cm9 ics

First of all I'm on AOKP 715 m6. My gps was nonexistent even though it was good on earlier versions. I was running a modded vle radio which i don't remember the source. Anyways, i flashed tdj's modded vle radio in one of his threads and gps initial locked on in less than 5 mins. It then locks on in less than a min after that.
At first i thought it was the kernel, so i flashed different ones, but no changes. however the radio definitely fixed it for me on AOKP.
So to those with gps problems try flashing tdj's modded radios. Sorry for being lazy on my phone and not linking them.

This was discussed months ago. Its the basic reason modded radios were made. Apparently the RILS break GPS. So yes GPS won't work unless you flash one of the modded radios, as you found out by accident lol.

I am not using a modded radio I am using the one that came with the ics official update uvle1. And I am running AOKP M6 7-15. My GPS is the best it has ever been I get instant locks even indoors. And It is accurate too. I have also used other roms and had the same results.

yeah i remembered that discussion, and I flashed a modded radio and it worked for most ROMs. I was then really bothered that my uber great locking GPS was no more... I seriously thought I flashed TDJ's radio because I had a file with the same name in my sd card. So I was bummed and decided to test kernels because thats like testing 2 things at once lol. But yeah I ended up checking the md5 of the modded radio i had on my sd card and it turns out it wasn't the same. Must have gotten it from a different thread even though the file name was the same.
But yeah it's just a little reminder to those who have GPS problems, that even though you may think you have a perfectly working radio... you should just flash TDJ's radio mods just in case.
Just flashed TDJ's modded UCLE1 radio...still no luck with GPS

What do you guys mean when you say "breaks GPS"? I am trying to determine if my problem is similar to yours.
My problem is not really an issue with the GPS but an issue with Google Maps. When I use navigation from point A to point B, say Schaumburg to Chicago, it'll always speak directions as if it's going from point B to point A, although all the on-screen directions are correct.
I uninstalled the app and reinstalled, but have not yet tested to see if that fixed it.

Yes this is what I have to do every time I flash a ROM and GPS breaks. I made a thread about it and there are also 2 more threads. Its a zip file you flash through cwm. Also people don't forget that if you're on cyanogenmod that you have to go into location services, GPS source and tick "use internal GPS". Or else GPS will barely work.

didn't know he had a ucle1 radio, he has a uvle1 radio though maybe try that one.
If it is the first time you're trying to lock on, it might take a while, you should turn off wifi and data while leaving your GPS on. Stand outside with it on for 5-10 mins or so, it should get a lock on. After that your GPS locks quicker the more frequent you use it.
I think a lot of people would expect GPS to lock on right away, this only happens if your phone has recent locks to the GPS. I find it best with wifi and data off and to just leave the gps on and google maps on.
btw i've tried the AGPS patch before, but if you have a crappy radio it still won't connect lol.
Here's the screenshot without data or wifi. This is inside my house. Notice the gps signal has a constant dot in the middle, i know for aokp this means i have locked on.probably the same for cm, not sure about tw, haven't been on that for a month.
Anyways it has went as low as 4m, so pretty good. This is without apply the patch.

Network registration takes years

There have issues reported with the uvlh1 modem. Perhaps you have a very weak signal? Maybe flash a different modem?
Well. I have tried other radios as well. Whenever i restart my phone, it takes time for the network to register. How long does it take for your network to register after a restart?
About signals, the signals are full in my area.

I'm having the same problem /: It doesn't matter what Radio i flash either.
It takes about 4 mins to almost half an hour to register.
I just booted into Recovery to do something and then rebooted and its almost been an hour and it won't register. I'm without signal right now, all I have is Wifi.
I can reboot it, battery pull, search for network (T-Mo and AT&T both appear, but when I tap on T-Mo it stays registering forever) and nothing.
This is driving me nuts. It's been going on for almost a month now.

Gps issues

There are no posts in here about it, so am I the only one with issues? Signal loses lock about every 5 seconds, and bounces me all over the place in Google maps, and Navigon. I'm completely stock. I downloaded a gps app, and it's locking on to 12 or so satellites.

just a "duh" note, make sure GPS is on and not just network location, I'm sure you all have but it never hurts to triple check also check your powersave mode, not sure if they may have an effect on it.

Faster fix and top ntp do the same thing it changes the GPS server from a generic one to one to what part of the world you live in
Then use GPS status/GPS test to update agps. Bam good to go. As long as it's not a hardware problem

Same here. I also tried bending the "leaf contacts" on the phone so the antenna makes a good connection.
My phone can see 25 satellites but it can't get a GPS lock, any ideas?
I have had serious problems with GPS on custom ROM's (among other issues). They would show the satellites, but it worked like garbage.
I did a full wipe, and ODIN'd to stock, and it's been great ever since then.
Have you tried making a nandroid, and doing a factory reset and full wipe, to see if it works well after? That should allow you to rule out if it's hardware related or software.
