Poor GPS performance.

Well if these mixed, and extreme one way or the other results, are indeed the case then I guess the bitc*ing is that there is a large percentage of us being affected by a severe GPS hardware problem and need to keep exchanging our phones until we get one that works or go back to phones that don't have this issue, because I can confirm that side by side my X works perfectly with the same settings as the Epic which does not. Also, there are no other phone forums where GPS has been such a hot topic, which is definitely fishy.

Can you please post a picture of the Google locate feature on both phones side by side after letting both handsets "fix" for a minimum of three minutes with both handsets OUTSIDE not in a building?? I would like to see the difference.

I pulled out my video camera with the intention of doing a side by side with the Droid X - and I'll be damned if I couldn't duplicate the problem this time. Yesterday, before I left the Sprint store, I enabled both AGPS and Satellite GPS, and while it found my AGPS coordinates, it would not lock a satellite during my 10 minute drive home. I fire it up again this morning, and bam it locks onto AGPS with a minute (albeit about a mile from where I live), and the satellite coordinates about 20 seconds later, followed by an accurate position of where I was. So I have no proof for you at the moment & I'm not about to carry a video camera with me everywhere I go. FML. I've had a few cars that have behaved the same way, where I have an issue, take it to the shop and then bam the problem goes away when they look it over and can't find anything wrong. :mad:
 
I have used the Epic's GPS for the past three days where ever I go to test it. Mine seems to work perfectly in terms of accuracy using Google Navigation, the boot time is my only gripe; it takes longer to get a fix than with the Evo and won't "lock" indoors like the Evo usually does.

The other "issue" the GPS as implemented on my Epic seems to be aGPS only (don't know for sure if this is the way is designed to be). Without cell signal it will not get a fix no matter what I do, renders NDrive useless. The Evo can easily get a fix without any cell signal, a definitive advantage here for HTC Evo when GPS guidance is needed on a poor coverage area.
 
My gps works perfectly. BUT my agps doesn't work at all so none of my location aware apps such as beautiful widgets update. Is anyone else seeing this at all I see a lot of gps not working threads but no agps not working threads any help is appreciated

On the Droid X, there is a 3rd setting - the Epic doesn't have - for GPS, and if I'm not mistaken the EVO also has this. I'm not sure if it makes any difference or not. I could never figure out the difference between the first and 3rd checkboxes.

Wireless - this is triangulation, gives you a location without using the gps.

Agps- this uses wireless towers to help your real gps get a faster lock.

Thanks. So does the Epic not have triangulation then?

I actually do think this has triangulation. That second setting after the enable GPS setting says that it uses wifi to find your location. I think AGPS is automatic when you press the GPS setting.

i don't have my Evo with me right now, but I don't recall an aGPS toggle present on the menu.
 
When static the gps picks me up instantly, today I got lost in sacramento and it couldn't find me while we were driving (about 50-60mph). It seems that it would time out before it could triangulate, when I turned on wireless networks it found my general area and then would get an acccurate gps lock within 10 seconds.

I also tested the gps a few minutes go and there were 8 satellites in view and 8 in use, and 98.4" accuracy. Although when I looked on google maps it was only 3 meters off from my actual position, usually its only a foot or two.
 
I thought I had GPS issues then I found that if I make sure I turn off my wireless connection and use 3G for data I got a lock extremely accurately in less than 5 seconds INSIDE my house. Not sure why that matters and it may have already been discussed in this thread but I haven't had a chance to peruse yet.

When I was on wireless only I couldn't get a lock period.
 
My GPS is only able to get a fix when my wireless data connection (3G) is on; if I turn off the radio, the GPS quickly looses the fix and can not lock again until the data radio is on. This would suggest to me my GPS only works in assisted mode (aGPS), however some of you indicate you are able to get a fix with the data service off.

Can you confirm that your GPS is able to get a fix without network assistance by doing the following: put your handset on airplane mode, then do a reboot and when back on, use the GPS without turning your data on and see if you can get a fix. Then report back...

This usually suggests that your handset is operating on aGPS mode, the GPS receives data from the wireless service about satelite position and times to assist (hence the aGPS or A-GPS) the GPS chip in getting a position fix. This is a good thing as it allows the phone to locate your position fast and accurately.

The bad part is that if the GPS chip is unable to obtain a fix without the use of this wireless service data then it becomes useless whenever you find yourself outside a service area. Some phones have stand-alone GPS functionality (the Evo for example), others don't.
 
If your gps is on and the gps icon in the notification area is green but you are not using any map or navigation apps, is the gps always looking for a signal draining your battery or only when it is being actively used?

no, just when called upon
