GPS Not Working?

**phgarman** · 07-24-2008, 02:06 PM

I've got an AT&T 8310 with enterprise data plan and running OS v4.5. If I go into Settings\Options\Advanced\GPS, I don't have any coordinates...everything just has zero's.

GPS Data Source: Device GPS
GPS Services: Location ON
Location Aiding: Enabled

Every GPS application (such as google maps) doesn't use the GPS either. I kind of have the feeling that a firewall rule or something blocked use of the GPS...I seem to recall getting a message and I might have accidentally hit deny or something. Where could I check this?

What could be the problem?

Thanks!

When in the GPS options do you have an option to refresh GPS? It will search for satellite and then you should see coordinates

Yes, I do have that option. When I select it, the location information changes to "Scanning for Satellites...". It stays on this message for about 5 minutes, then goes back to all zero'd data.

What app are you using that's showing the zeros?

I'm not using an application. I'm in Settings\Options\Advanced\GPS:

Latitude\Logitude\Fix Time\Number of Satellites\Accuracy all are zero or none.

This might be a stupid question, but are you outside?

Ok. Must be a new feature in OS 4.5. To answer your permissions question, look in Options/Advanced Options/Applications and find the module that corresponds to your GPS. In my case, I find the app I'm running. Since you aren't running one, I don't know exactly what to tell you to look for, but when you find it, select it and press Menu and you can edit the permissions. Try setting any that are at "deny" to "prompt" or "allow."

Yep, I'm in the wonderfully flat and treeless Texas. This has been going on since I got it about 4 days ago...and I've been all over the place inside and out.

I set all the permissions to "allow" for all applications, the os, etc. I was searching around and found this post listing the "default" values...however, I can't seem to find where this list of security settings is in v4.5:

Here are the default permissions in v4.2
options > advanced > applications > edit default permissions
Connects Custom
USB Allow
Bluetooth Allow
Phone Prompt
Location (GPS) Prompt
Company Network Prompt
Carrier Internet Prompt

Interactions Custom
Interprocess Allow
Device Settings Modification Allow
Media Access Allow
Module Management Allow
Theme Data Injection Allow
Keystroke Injection Deny
Browser Filtering Deny
Screen Capturing Prompt
Security Timer Reset Deny

User Data Allow
Email/Messaging Allow
PIM Allow
Files Allow
Key Store Allow
Key Store Medium Security Allow

I'm thinking it must be one of these security settings...if I can find them

If you're right, you're beyond my help. I have a Verizon 8830 running 4.2.2.176, so I can't replicate your setup and don't have a working internal GPS. When you solve it, be sure to post the solution for the next guys.

Strange..

Which 4.5 OS do you have loaded? I can say that with 4.5.0.52 my GPS works better than with any of the previous versions. Prior to .52 the refresh option almost always failed to find any satellites, but Telenav worked. With .52, refresh picks up satellites very quick, usually in 10 - 15 seconds.

i had this problem and had the phone swapped out. problem was resolved
not saying that is the only course of action. just what worked for me

The latest..8310 4.5.0.52 rel75 TIM ITALY.

I'm pretty sure mine works great too, but I believe it's a security setting that isn't in the same place with v4.5. I believe I might have denyed the initial GPS firewall prompt. *sigh*

I think I'd be tempted to wipe it, just to go through the permission prompts again..

I think that's what I'll end up doing.

Does the BES enterprise activation get reset when you wipe? Or does the backup\restore save and properly restore that? The BES admins at my work are sooo slow with getting that setup.
