Lots of 3G dropouts!!

Hello all,
My issue with this phone has been mentioned here: http://www.google.com/support/forum/p/android/thread?tid=384f4daca48e10b1&hl=en
My basic problem is that atleast 4-5 times each and every day the 3G connection suddenly drops out. As the link says, I see the "up arrow" blinking, but no action from the "down arrow" next to the 3G symbol on the top right corner of the phone. At this point, all apps complain about no network connection. About 45-60 seconds later the connectivity is restored automatically, and I can happily do anything on the Internet again.
I've had the phone for 1 week and this happens regardless of location or signal strength. So I've had this problem at work, at home, while driving etc. The dropouts also occur even when the number of bars indicating signal strength is 3 or 4.
These constant dropouts are really infuriating and I'm not sure if it's a network problem or device problem. Has anyone else had this? I'll be very grateful with any suggestions.
Thanks.

same here, I dont know if this caused by my ****ty provider.
I'd like to try new radio but it seems it still has problem with bluetooth

I had this problem too, it was very frustrating. However the new radio 5.08 appears to have solved the issue for me (I don't use BT currently so can't report on that aspect)
Ask a work around, try setting your phone to "WCDMA Only". That improved things for me previously.

I have also had this problem and I am on stock FRF91. It really slows me down when I need to quickly perform a task that's data related.

This is exactly what I'm doing.
The internet oon the phone barely works on 2G, so I lock it on 3G only mode.

Have this problem on stock.
Also drops calls when it goes down to 1 bar (in areas where another phone with the same provider will have 2-3+ bars)

This has been discussed in detail here

Thanks for the replies guys. So if a mod completely gets rid of the problem, that means it's a software issue right? What's this radio 5.08 that solves the problem? Can I apply this chagne without rooting?
I'm in Australia, running stock 2.1-update1 (EPF30).

you could try update to Froyo
it has new radio

Oh, so Froyo will fix this issue? That's great.
I don't mind waiting for Vodafone to release Froyo then. Shouldn't be long now.

Hmm I see. I'll wait and see I suppose.
I'm surprised if it's just a software issue, why it hasn't been released to everyone.

3G and APN
I have froyo it does not solved the problem.
I also have an issue with the APN, I can't change the MCC to 425 from the default, it wont save it, any suggestion?

I tried going though this, but unfortunately it's not obvious to me what I should be doing. I'll include my details here:
Firmware: Android 2.1-update1
Baseband version: 32.26.0024U_4.04.00.03_2
Build number: EPF30
Could someone please help me out here? Is it possible to upgrade just the radio version somehow?
How do the CM mods manage to get a radio version better than Froyo?
Thanks again.

[Q] Froyo GPS Lock Problem

Ok...so after updating to Froyo my GPS is not working. Not only that, my phone can't seem to find my approximate location even after enabling "Use Wireless networks". I used GPS Status app from the market and I confirmed the phone was seeing several satellites, but it was getting no lock. I had no problem with my GPS with 2.1 aside from losing my location occasionally when I drive through the downtown.
Is anyone else experiencing this issue? I'm running my phone on Rogers network, unlocked and rooted.

You didn't say what version of Froyo you are running but I'd change my modem file and use one of the alternate ones that DocRambone has. There's a thread on this but I find the ZSJPE (Hong Kong) version to be superb (and our company develops an app for the phone that uses GPS for golfers) - very quick, very accurate...

Oh I'm using JK4 from Bell..and kernel version 2.6.32.9....
Edit: Oh and I have also done factory reset/cache wipe...and it's still doing that...I want to see if I can fix this without changing the modem file or anything like that...

I'm having the exact same problem since upgrading to the official 2.2 release from 2.1
EDIT: Bell Galaxy S Vibrant, Unlocked and running on Rogers. Not rooted.

Ok...so I'm a bit relieved to know I'm not the only one out there...From the things I've been reading it doesn't seem to affect phones running on Bell networks..but shouldn't GPS be not affected regardless of the network you're running on? I don't see why it's refusing to get a lock...

I can't believe no one else is having this problem, maybe we're the only ones unlocking??

I was also having this problem. I updated to bell froyo using kies, and am unlocked using rogers. I loaded gps test, set it so it wouldn't shut off the screen, and let it run for about 30 min in a window. Eventually it got solid lock on a couple sats and it now seems a lot snappier to get a lock.

Ok, good news! At least for me anyway... I decided to try keeping my GPS on and let my phone to try and find my location..however long it was going to take. I don't think it took me 30 minutes but it took me good 10 minutes before my GPS found my location. I think the problem was because I'm having trouble getting location information based on my wireless network and updating to Froyo and doing a factory reset must have deleted my satellite schedule. Right now I'm just so glad to find out my GPS isn't broken! :-D You should try the same thing I did.

Thanks Yeria, that sounds like the problem we're having.
I do find that if I give it enough time, It will get a pure GPS lock, but I'm not getting any aGPS (the network based)
That thread you link sounds like the solution, but unfortunately I can't seem to access the file they tell you to modify

I too have GPS problems right after upgrading to official froyo. And it kept getting worse when i tried custom ROM. I tried factory resetting and format all my sd card, cache wipe etc hoping that it will return to normal like when i was in 2.1 elcair but to no avail. I don't know if some bad code was left behind when i did the official upgrade through kies. All i can say is it was working fine when i was at 2.1 then suddenly went bad after 2.2.
By the way, my problem is my GPS lock kept of disconnecting every now and then thus rendering my GPS useless as it kept on displaying my location as "off road" even though i'm on a clear highway with clear and bright skies!

ahh, if I root the phone I can get to
/dbdata/databases/com.google.android.gsf/gservices.db
unfortunately, this phone doesn't have sqlite3 installed!! I need to try and find that
EDIT: Found a copy of sqlite3 and was able to push it to the phone. edited the db as people suggested! I'll have to test it on Monday

Based on what I have found so far, and assuming your aGPS or any other wireless based assistance features are not functioning properly, doing a reset and cache clear will not help with your GPS at all. I have read that the phone will try to download the satellite schedules directly from GPS satellites if you're using purely satellite based GPS option. It'll be slow so it will take longer to get a lock and that's why phone will use other means to shorten the lock time. Once the schedule is downloaded, they said there shouldn't be any problem until the schedule expires, at which point you will have to download the schedule again.
I think the reason you're losing lock frequently might be because your phone doesn't have a clear view of the sky..? I used my phone GPS to drive around Toronto, Vaughan and Mississauga last night for at least 4+ hours, and I did not have any problem.

So, I tested today after updating the db.... no agps still..
Anyone else still.having issues with agps?
GPS works, just no agps since 2.2

This is why I unfortunately have to use an old Tom Tom GPS!

i'm having this problem too. i finally got it picking up quickly on 2.1 but once i updated i haven't been able to ever get a solid lock. has anyone found a solution yet??

Now that my wireless location service is kind of working I thought aGPS should also naturally work but I guess not... My GPS takes a pretty long time to start up and I haven't found any fix for this..
It's funny because I didn't really have any problem with my GPS with 2.1 but now I do with 2.2...

Serious GPS issue..

I have tried every single GPS fix out there on this forum but my GPS is still not working... inside a building GPS test says that there is no satellite in view.... outside I see about 6 and locks to about 3 or 4....
(But it takes like 5min to lock)...
Is there something wrong with my phone? And btw I'm running cognition rom and I'm rooted.(if this has anything to do with it...

Try the Darky port that uses Da_G's fix. Best GPS experience I've had so far with this phone and the only thing that has realistically improved performance.

my best gps performance has come from two roms
Chronus and Doc's newest rom.
Did you change any supl settings?
For me the supl.google.com settings never worked as well as leaving it @ www.spirent-lcs.com
build = 1007.

I have had great gps since i switched to assonance, latest version of axura worked for me as well, you may want to give them a try, or try their gps settings and modem over cognition.
If that doesn't work you may want to scratch/erase the white contacts of the cover as one post said to maybe increase its signal.

I would return it..you should be able to lock faster than 5 mins and see more than 6 satellites

I agree with fldude... my first one wouldn't see anything. My second one works as well as anyone's. Exchange it.

I really can't return it cause I didn't buy this phone....
So I'm gonna try all the roms... thanks for the info guys
Sent from my SAMSUNG-SGH-I897 using XDA App

Most of the newer ROM's have GPS fixes built into them
I'm running Assonance's latest build and although it's not perfect - I usually get 8-10 sats in under 15 seconds to lock-on.

I just started using the latest assonance and it has great gps thanks.

Even if it's a gift you can return it, unless of course you've "borrowed" it...

i agree mostly that that using the google server didn't help me at all and the roms you mention are quite good. but i have the bug where the daemon crashes on chronus, but cronus has the ability to lock very very fast on my phone, i have had great luck with captivate builds in general. da_g's files fix the daemon crashing mostly but are not considered a fix. there is still an underlying issue that causes eratic behavior in certain situation. da_g has yet to pin it down but it may be an interference issue.
OP you may have a poor contact at the antenna, some vibrant users were cleaning the contacts for the antenna, there are many antennas and im not sure which is for gps.
also you may want to try with/without backplate, and clean the contacts on that. some users have posted numbers showing marginally better signal without the backplate.
also i have yet to do real testing but anecdotally the old jm9 libraries seem to behave less badly. it still jumps the position around in some situations but it just seems like it jumps less, i will do a mytracks comparison soon. but for the issue the op is having it seems to me that i get faster locks with the newer files, particularly from jj4.
lastly the modem has a great effect on the gps signal. for ability to lock jl3 seems the fastest. but to be honest i think the phone didnt jump the position around as much on jj4 or ji6 which give up hsupa and should be used with the a captivate rom. jk3 and jk4 were also good maybe better with the position jumping thing than jl3.
EDIT: one last thing is to try the gps restore app. i know it says it only resets lbs test mode settings but it also clears "something" that has helped with a bug causing the daemon to crash on my phone(it doesnt crash on every phone like it did on mine) the only other thing that i tried that was able to "fix" that bug was to do a factory reset. clearing gps data never helped. so the error seems to be in data somewhere but is not cleared when you clear gps data in lbs test mode. the samsung app also did not restore my lbs settings to factory so the ad may be mis-informed. i think of it as a easier way to clear gps data which at times yeilds better result, it is not a fix. your experience may vary.

[Q] GPS...

I recently swapped my original Captivate for a new one because it had random shutdown issues. However, the old one had no problems getting a quick and accurate GPS lock with various ROM's and modem versions.
This new Captivate will NOT lock at all. Both stock and running custom ROM's, JL2, JL3, JK4, JPY, JM9, etc. I've double checked my GPS Fix settings, cleared GPS data, reset and reflashed multiple times, but my GPS does absolutely nothing. Running LbsTestMode, all that happens is the GPS icon in the notification bar useless flashes, but nothing appears in the test menu, it doesn't appear to be searching for satellites or anything.
From this information, does this sound like a hardware issue? Getting my Captivate exchanged the first time was a big hassle, and my parents seem very unwilling to do it again (as far as they're concerned, if it can make calls, there's nothing wrong with it).

In the LBS Test Mode make sure that the Server is set to supl.google.com and port is 7276, And then delete GPS data.. You should get a lock-on pretty quick

Already did that. The problem isn't exactly getting a lock...LBS Test Mode doesn't even show the GPS trying to get one. On my previous Captivate, if I was indoors or somewhere where a lock was difficult, it would still show the GPS hardware scanning for satellites. This new phone doesn't even do that.

Hmm.. try the Phoenix 3.0 with the Kernel and Modem that comes with it.. and then try GPS.. Axura and Phoenix ROMs are known for it's awesome GPS

Eh...nevermind I guess. This phone is only 2 days old and it has a defective USB port, so I'm returning it. Starting to feel less inclined to get another Captivate, even though it's an awesome phone...when it works.

I swear they do this to discourage exchanging phones. That sucks dude

This is frustrating, WHY can't I get this GPS to connect?!

I have never been able to use turn by turn. I've used Google Maps after enabling GPS and WIRELESS NETWORKS AND THEN WHEN i SWITCH over to Google Nav it says Searching for GPS....but yet it gets me text directions on how to get there and if I make a wrong turn it doesnt update with how to get there from the current location
Ive seen videos of people being able to use their GPS and Ive had this phnoe since last year. What in the hell...please help.
Baseband:
32.36.00.28U_4.06.00.12_7
Kern:
2.6.37.2
Cyanogen 7.0 RC2

If you can't use GPS in any application I would say it's hardware related and you need to send it in for repair/replacement.
I would assume you have the newest version of Maps and you have wiped and tried the stock rom already.
Can you provide logs?

Oh damn Im out of warrant :\
Im frustrated
and the weird thing in Google Maps, when I have GPS and wireless network enabled it grabs my location within about 500 yards of my real location but on Google Nav it says searching for gps and when I use the GPSstatus app it doesnt lock or anything it has that loading icon

500 yards is your network location. That would be flat out awful and useless for GPS. My GPS fix is usually in between 3-10 meters.
Download GPS status from the market and see what it shows.

Oops did not see the last line where you already tried the app.
As said before try a full wipe/ restore to stock if you haven't already. Other than that it will need to be sent into HTC to be fixed.

I am getting problems where the GPS lock takes far too long, but it does eventually get there.
I am on:

Baseband - 32.50.00.32U_5.12.00.08
Kernel - 2.6.35.7-59423-g08607d4

All pretty standard stuff, the issue really is that it used to work great on 2.2 & earlier radios, so I guess the question is what is the best radio for 2.3.3 & GPS ?

If you don't have the same issue, then why post in the thread with a different issue? Start a new thread for a separate issue. Fwiw, stock Gingerbread radio is 5.08 which is what you should be using, not 5.12.

I think it's more of a CyanogenMod 7 issue since I couldn't have locked the phone with RC2 also. Try updating to RC4 it works for me now.
