[HOW TO] fix GPS Problem with custom ROM's!! - Thunderbolt Android Development

Hey everybody,
Just wanted to let you guys know that I was messing around with the GPS setting trying to get my location to be correct on the first try with Google Maps. After tinkering, I found that if I unchecked the Google location Services box in menu>settings>location my location was read almost instantly and accurately! Bidding me farewell to Google Maps saying I was 50 miles away from where I really was.
Hope this helps for everyone, I know it did for some friends.
Let me know if it works, and good luck!

Cool. My Google maps tracked exactly where I was. Even the corner of the intersection(where is my house is located on the street)

I installed the zip file, after it took about a minute to lock on, and after it locks almost instantly. Is this normal to take so long first time locking on?

If you are using a custom ROM then yes it is. I know that from my experience, even after installing the zip I was getting a little lag and even getting the wrong location for about 3 second then it would lock on correctly. Doing what is mentioned in the original post fixed that problem for me entirely. Hope this answers your question!

This is the greatest info I have read regarding the GPS issues with the Thunderbolt! Such a simple fix but one that doesn't make sense at all. Regardless thanks a heap OP! A mod should sticky this information for all to see!

Seems to break location altogether for me when I disable Google location services. Can't get a fix in maps or the sense flip clock weather.

Great bud! Glad I could help!! I would love for a mod to sticky this, it is such an easy (odd but easy, lol) fix yet so many people absolutely hate that the gps won't work right. Hope more will see it and get their GPS working the way it should. Again glad I could help. That's the beauty of a community like this, between all of us, we can make so damn phenomenal phones! lol

Sorry about that, i figured it would be safe to call it that since there is clearly no true fix to this issue anywhere as far as i know at least. Please do correct me if I'm wrong. It worked for quite a few people I know so I thought i would try to help some people out.

Thanks. At least its more accurate now.

I think what we are seeing here is that the gps is not using agps at all. Proper operation would be the agps actually assisting the quicker lock. Instead the agps and gps are working separately and by disabling agps....the locks should still be slow no matter what.
It is for me anyway.
That said, standalone gps will always be more accurate.
Sent from my ADR6400L using XDA App

Funny thing is, standalone how isn't even working, since when you turn off Google location services it shuts off completely. Also for me it seems to be attached to WiFi so if its off it says I'm within a 2 mile wide area...

No...that's how agps works. It will be within a few miles.
WiFi triangulation will always give quick locks.
Standalone gps does work, its just slooow.

I too was having the lag in getting a gps fix. My solution was:
1. Download GPS Status from the market
2. Under menu/tools select Manage A-GPS state
3. Press reset
4. back to menu/tools Manage A-GPS state
5. Press download
I now get instant fix.
Hope it works as well for you.

This just proves ephemeris data is not being downloaded, or used by the GPS automatically. I'm sure HTC will fix it in the future.
I hope, anyway.

Worked for me. Going from no lock to lock in under three seconds.

why is this in Development, nothing was developed, just a simple suggestion of changing settings which doesnt work for everyone.

[Q] HTC Aria stolen - advice?

Is there anything I can do to get it back or track it, or is it a lost cause?

I'd hate to be the bearer of bad news but to MY KNOWLEDGE you're out of luck. Now, that's not to say there isn't a way hence the all-caps "my knowledge". Sorry for your misfortune bud...

Sorry to hear about your phone being stolen. I would troll craigslist and ebay, but even if you find it on there it would be hard to recover.
As for advice, install my lookout on your next phone. You can locate your phone from any computer and also make it "scream"
yeah look out is the way to go...
Pretty much a lost cause at this point. Next time, if there is a next time, you may want to look into apps like the above mentioned or Where's My Droid, which may help since they allow you to locate the phone using the GPS.

None of the apps mentioned before will do you any good if you have GPS turned off. Tasker can remotely turn on GPS, locate your phone and send you the location by simply texting a key phrase.

This is something you have to build in Tasker. I have mine set to enable GPS and open a GPS tracker app that can be monitored on the web. Only good if sky is visible.

You can just download Tasker profiles from the Tasker wiki site, not that hard. I have tested this a few times and you don't need a sky view for this to work.

No, pretty sure it just tells GPS where to look first, then if it doesn't find you there it looks elsewhere. It may just take an extra few seconds, but I think it basically gives it a starting point.

I have same issue. With about all custom ROM/kernel combos I get location errors or my sense clock widget tells me I'm in Philadelphia when I am in Kansas, unless I simply turn WiFi on. Not connected, just on. If I turn it on and my location works....
Worked great for me, GPS was always taking several minutes to find me, but after this it locked on in about 10 seconds.
Thanks!

There is also an app that does this. It was very popular with the samsung fascinate users since their GPS lock times sucked at first. Thanks though

My GPS issues appear to have been weather related. Worked fine today.
Wow fast lock!
No difference for me. Mine locks instantly with or without the mod.
I have a problem where if I haven't rebooted the phone for a couple days, the GPS doesn't locate me in Maps, Zillow, etc. Launch Maps or Zillow, it will just sit there with the big blue shaded circle with the center no where near me, and the GPS icon flashing... or Navigation saying "searching for GPS" when trying to get directions..
Power off/on... GPS finds me quick.
Will this mod fix that?
Another quick fix for GPS that I've found is GPS Status. Download GPS Status from the Market, click menu->Tools=>Manage A-GPS state->Download. It just makes sure you have the latest Assisted GPS data from the web.

Better GPS lock time?

Hey guys after I downloaded sygic navigation I'm starting to use the GPS a lot more. It just takes forever to find a lock when I'm not even moving. Is there any way to decrease the lock time? I've already flashed the GPS file for my area but it still takes awhile. Anyone have any ideas?

Thats what the angle death .zip files do. But thanks!
Actually now that i realize it, its not the actuall locking time, its that say when i have sygic open, and i leave the program, it drops my GPS lock and now i need to wait for it to lock again once i re-enter the program and that is VERY annoying. Same thing with Google maps and my weather app for looking at radar.

Google Now discussions

Hey guys,
I opened this thread to see how people is using Google Now nowadays. I found myself excited about the launch of it, but now I found it pretty boring and useless. First, I sometimes use it for weather, the other functions are not really working. Everyday I'm going to my workplace, at the same hour, working in the office between 9 am - 2pm and 5 pm - 8 pm. I have the location history enabled, the house address and workplace address both added, I see the statistics in my dashboard and my current location in latitude (no check-ins however), but Google never advised me that I need to leave from home to be in-time at work or reverse. The only things I got was some live scores and some random mistakenly notifications like "78 minutes to home", while I was only like 200 meters away.... Also, I found that if I search my job address in Google Maps, the location is correctly shown, but in dashboard, I'm getting that briefcase (workplace icon) wrong positioned with around 80-100 meters. Otherwise, Google Now is answering to all my questions and working pretty good, but I don't find it really smart...
Google Now works well. It is just that Google Maps have a long way to go. Many routes it shows are not the fastest, etc.
Like you i was pretty excited about the whole thing, the problem is that the tradeoff in battery life simply isn't worth it for me.

absolutly agree with you..
i noticed that when i'm with wifi enabled, if i look at battery usage, wifi is always connected even in standby (with wifi disable option active)
double checked and if Gnow is disabled wif act as it was supposed..
It would be great if there was some way to change the location poll frequency to maybe every 15 minutes or whatever, rather than the default.
Sent from my GT-I9300 using Tapatalk 2
I see no huge changes in battery life since I activated the location and search history in my phone just for Google Now. The problem is that the check-ins are not regular, I'm getting bad locations sometimes, so Google Now can't give me information about when I need to leave home because of traffic or so.... Nothing. Got one notification in a whole month and that one was wrong as I said in my first message. No idea what I need to do instead. Check in at work at the same hour daily? Why the pin sometimes is flying like 500 meters away from my location (that's what I see in dashboard) while the google maps app is showing my location with 16m accuracy even if I'm in a building?

You can change the way each card works and when you want them to appear, also changing the priority of the weather card to low also helps.

Menu -> Settings -> Google Now -> Switch to OFF. then you can delete the location history and search history in Google Dashboard and disable the latitude and all the rest of stuff or you can simply reset the phone and don't activate it again.

He means that the Google is checking your location randomly instead to checking it every 15 minutes or so.
The big question is....how to make Google Now know that I'm starting the work at 9 am, so I will get those cards saying "30 minutes to work" or something like that. Google knows that I'm working as I'm getting those fancy graphics in the Dashboard (https://maps.google.com/locationhistory/b/0/dashboard) saying that I'm working X hours per week and Y hours I'm home, but the data is not accurate perfectly. I reset the data but same story now. Not sure if it's because my location sometimes jumps some kilometers away even if I have the wifi and gps enabled. Do I need to use Latitude and autocheckin or something like that to get accurate data ?

Google Maps Navigation

I have issues with Google maps navigation. It's stuck at the "looking for location".
I tried it on my 16GB and my wifes 8GB and got the same.
When I tried to navigate on Copilot it worked well so I don't think it's the GPS issue.
Anyone else has similar problem?
This may or may not help, I am just tossing it out as something for you to try. My google navigation app was doing the same thing. It turns out because I switched off location access (to see if that conserved power) it stopped google navigation from working properly. So check your location access settings and make sure you have them turned on.

GPS test locks onto a satellite with no problem.
Check Settings->Accounts->Google->Location Settings and make sure the "Let Google apps access your location" is ON.
Mine did the same thing, when I tried to re-plot the course whilst in a call.
It appears to only do it when in a call, too.
A reboot resolves the problem. Slightly annoying.
