Not to cloud the waters with another post (there is another) about the Evo Shift 4G and it's lackluster GPS but I'm making some headway with the issue. I need to get Sprint and HTC's attention though.
I have 2 HTC ES4G's and both have the same problems with the GPS. It will NOT hold a lock more than a couple minutes. My wife's phone is still at original factory settings with no upgrades to firmware, PRL or HTC software. Mine has all updates.
our navigation is all but useless. Telenav and Google both continually re-route every couple minutes because the phone will triangulate to cell towers as soon as it loses the satellites. This usually puts me about a half mile to a mile from my real location causing the navigation to re-route, only to do it again when the GPS finds me again.
I downloaded GPS Test by Chartcross (Free) from the marketplace on the ES4G and a similar product on my company HTC Imagio. The Imagio will INSTANTLY grab 7-10 satellites and often shows resolution in the 3-7meter range. The ES4G on the other hand will bounce from zero to 7 satellites and everywhere in between. this is in my car, or out on a picnic table in front of the office, in my back yard...it doesn't matter. sun or clouds...no change. the Imagio is rock steady...in fact I used to do some geocaching with it. I had an AT&T Tilt before the Imagio and it's GPS was the same...that's the device that got me turned onto geocaching in the first place.
I've called into Sprint Tech Support, there are no GPS chip updates...I TRULY believe this is a software issue right now, and have no reason to believe otherwise. Sprint is willing to replace my phone and i'm scheduled to go get a replacement on thurs or friday (3rd party reseller kiosk that didn't stock any phones is ordering me one...company store would not do the swap). I plan on immediately firing up GPS Test and Google Maps in their parking lot to see if it's any better. I want to also compare it to the Evo. and any other HTC handsets they have on hand.
I love the ES4G but the GPS has me wishing for a different phone. I'd sacrifice a little battery life for a GPS that works. Might be upgrading (?) to a Evo instead of the shift if this isn't fixed.
If any of you could see if you duplicate these findings I would love for you to chime in. you can get GPS Test
HERE
and another
heret
both work the same for me...
Thanks in advance for your help...
