Default [SOLVED] GPS aquistion on EC05

Folks I am now seeing symptoms of stickiness in the GPS cache on both our ec05 Epics. The symptom is GPS on, application requiring GPS on, and the device not obtaining any GPS after several minutes optimum conditions, followed by a battery pull and a GPS acquisition within a few seconds.

This was a known issue on older firmware, one I never saw with eb13, which I had for a month, but which has returned on both our epics wiht EC05.

Lets track this to see if anyone else has this. Please do not cloud thread with discussions of accuracy or results one sees within a couple of days of any reset.

I've experienced the same. And appears the dialer code to access gps startup mode is no longer availble.

After EC05, I got very slow GPS lock like 10 minutes. Before it was instant. I had my phone since Dec 10 with the previous release until the recent upgrade to Froyo.EC05

I really thought we were past this circle of GPS purgatory.

Last night, a friend and I took the wrong exit heading for Tribeca. Thinking I'd help and, since the signal in that area's good, I got out my Epic. Minutes went by and I couldn't get a lock. I did a reset, but before the phone could restart, my friend rolled down the window to talk to another driver. Never thought I'd say this, but I'm considering either picking up an Evo 3D in six months or a Shift for backup.

This is why I’m sticking with custom ROM’s from the folks over at the xda developers forums. I have yet to experience GPS problems with the ROM’s I’ve used from there. Currently on Bonsai 4.0 and I get a lock very quickly. Samsung/Sprint can’t seem to program worth a damn from what I’ve seen. A bunch of hackers and independent programmers have made this phone run far better than it ever would have on the stock crap Sprint/Samsung have been shoveling out to us.

Just my opinion, of course…

Just spoke with Sprint and they are getting reports of GPS lock problems on ec05. If it is the same problem from d118, I can not believe they fixed thi in the final of eb13 and then screwed it up again on ec05! I am especially miffed since they seem to have removed the user ability to set cold start as default as well.

How did it work after reset?

One good thing about EC05 update is that I can now get a lock on GPS when I'm indoors. Confirmed with the GPS Status app.

I'm having the problem on Syndicate Frozen, and I can confirm I also had it on stock EC05 that I got OTA. Symptom is that GPS works great for a while, then at some point quits altogether. GPS stop/start does not cure it, nor does AGPS State Reset from the GPS Status app. The only reliable way I know to get the GPS working again is to reboot. Wonder what's different about Bonsai that you are not seeing the same problem. Is this an EB13-based build? -Sean

I use GPS everyday for work and I have bonsai. I have not experienced one problem. My phone is seriously on GPS about 4 hour daily.

This isn't about where you can get a lock. I see no difference (improvement or degradation) in SNR or multipath rejection. It is about differnce in ebb13 v ec05 assistance data handling. Several users are seeing signs that something has gone wrong with that

Bonsai is a modified eb13 kernel. We are discussing stock EC05 kernal

Bonsai 4.0 is not an eb13 kernel, it's EC05. This is what I'm running and GPS works just fine with it.

Gps worked fine with eb13, but after update it no longer functions as well. I usually don't reboot my phone for several days. I notice that immediately after a reboot the gps works fine. Later though, It can see the sats but it never locks. If I reboot at that point the gps works fine. Thanks for breaking it again samsung.

Is this you claiming Sprint ID is not on EC05?
Froyo EC05 (DI18 users - Install instructions post 39)!

And looking at Bonsaa forums essentially everyone is rebooting for one reason or anotehr every 24 hours. Of course you are not having a stuck cache issue.

And this is a thread about GPS issues with OTA stock EC05, which is what 99.9% of Epic users have. As with the prior discussion of what was a verified GPS cache bug people with custom roms in constant develpment have a differnt usage habits, specifically booting and other cache clearing (known or unknown to them)

Irrelvent to the issue. please read the first post. this is not a question of when it works, whcih could easily be 80% of the time with the bug present but the conditions present when it does not.
Even when the major bug was in the software for 6 months it worked after a reset .

My comment about Sprint ID was incorrect...because it was actually EB13 that I installed on my wife's phone, not EC05. She currently has EC05 Bonsai now though...

Don't know about anyone else, but I'm not rebooting every 24 hours and still do not have a problem with my GPS. But sorry, I guess my input isn't wanted here so I'll keep my mouth shut. My bad....

I am having GPS issues since the OTA update. Seems not to be a problem with my RunKeeper app, but I am having problems with Sprint Navigation, Google related navigation apps (Navigation, Maps, Places, etc.), Gas Buddy.

Not having issues every single time but most of the time. Sometimes a reboot fixes the issue. Today, it didn't fix after shutting down and restarting about three times. I finally gave up.

I haven't yet tried a battery pull instead of just shutting down and restarting the phone. Very frustrating!

I can confirm this issue. I had my phone on for 2 hours, used GPS status/tool and gave up trying to get a lock, after 3 minutes. I rebooted and almost immediately got a lock on 10 satellites. Accuracy was 4 meters, in my house. It is random, though. Afterward, I had my phone on for another 2 hours and checked status, again. Immediately I got lock on satellites with same accuracy.

I am running midNIGHT latest ROM, which uses the Bonsai EC05 kernel. I realize you started this thread but, the bug doesn't seem to be stock dependent. slwelch confirmed the same issue on syndicate's EC05 ROM, as well. The only ones (above in this thread) who are not having the problem, seem to not understand what the problem is. Yes, GPS works and works well and with great accuracy. But, randomly, when the phone has been turned on for some time, it does not get a lock and a reboot is necessary to refresh the cache and get lock, again. There was a fix for this in DK28. I wonder if the same fix would work on this kernel. It would take flashing back to DI18 to find out. I'll let someone else try. I have everything else the way I want it, right now and can't be assed.

@Aero1:

Did you have the Cold Start workaround set on this phone before updating the OS to EC05? Not sure what the update would have done to those settings, or what the default settings are under EC05.

I've been meaning to install LauncherPro to run the hidden GPS Setup utility, now that the dialer codes have changed.

I cannot find LBSTestmode in launcher Pro Activities. If you find it, please let me know.

There is no LBSTestmode app on the Epic. That app is for the Vibrant, Captivate, and other GSM-based Galaxy S phones.

The corresponding app on the Epic (and the Fascinate), which have a different GPS chipset and thus a different utility, is called GPSSetup. The interface is not identical to that on LBSTestmode, but it is similar.

LbsTestMode.zip
Just got it from ptfdmedic (midNIGHT ROM dev at xda) You can flash it via CW or extract the apk and paste it in system/app. LbsTestMode opens and is working on my phone now. I don't know if the fix has made any difference, yet. I guess I'll know in a the morning, if I can still get a lock without a reboot.

Default Possible GPS Fix/Work Around

I just saw a GPS work around posted for another Galaxy S phone here on Phandroid, tried it, and it seems to at least partially work.

Download GPS Status and Tools. Use the tools to clear the GPS cache. For me, after that, I am able to use the apps that were problems for me since the update.

Again, my GPS issue is sporadic but most of the time. I just tried using this app for the first time, and it seems to work for at least some apps. Might be the app; might be that my GPS just happens to be working for these apps at this time. However, I was not able to use GasBuddy at all before trying this new app, and it is working for the first time since using the GPS Status app.

On the other hand, I still seem to be having issues with Sprint Navigation. I am only trying from inside of a building. So, it could be a reception issue. I'll try this in my car tomorrow.

I wouldn't place any faith in that utility, since it was made for a different phone with a different GPS chipset. Pushing its buttons might just be a Potemkin/placebo action, or the results might be undefined.

I recommend trying the GPSSetup utility instead, since that ships with the Epic and used to be invoked with the dialer code in pre-Froyo versions of the Epic OS. I am assuming that LauncherPro can find GPSSetup, but I don't have LP installed yet.

EDIT: It does appear that the GpsSetup.apk utility that used to exist in earlier versions is now gone. So it's not just that the GpsSetup dialer code has been deleted.

Yeah. It didn't seem to do anything for me. I just tried this old fix and will see if it does anything. It worked perfectly for DK28. The drag is that I had to flash back to DI18.

Thank you for that link. It brought me to another link where I was able to download the GPSSetup.apk for DeOdexed ROMS. I don't know if it works on EC05 but, it's worth looking at.

I have given this app a try. I still have the problem. Possibly the utility help inasmuch as I did get some things to work more than before. However, nothing is consistent.

The old solution worked perfectly. I haven't had any more problems since doing that. What I did different was instead of flashing DK28, I did the OTA update to EC05. Then I flashed midNIGHT v5.2 and all is well. I also made sure not to restore anything, aside from angry birds.

Here is an updated version of the fix for EC05.

Dont take this wrong but you are completely incorrect. that particular "old solution" was for the early test versions of eb13 froyo which had other different GPS issues from the cache issue. EB13 was actually fixed and had perfect GPS by the time of its official OTA.

the assistance cache issue seems to have returned with ec05.

I am afraid thst the GSP hardware, right down to the chip is different on Epic from the great majority of Galaxy S phones. So as far as commonality with other Galaxy S, the only practical one is Samsungs lack of care, resources and denial when it comes to GPS issues.


GPS status' cache clear and cache reloading commands also has no affect on Epics GPS assistance cache. It wasn;t writen for it and can force a clearing.

GPS status' cache clear and cache reloading commands also has no affect on Epics GPS assistance cache. It wasn;t writen for it and can force a clearing.
You sir are incorrect. This fix was actually from DK28 (pre EB13). It has fixed my GPS. Perhaps your GPS has had no issues. If so, I am very happy for you. I never had problems with EB13. I did with DK28 and fixed it with this (while many others were still bumbling around and wishing for the official Froyo because they were scared to use a beta). Afterward my DK28 had perfect GPS. I also did with EC05. Others have had issues with EC05, as well. The problems seem to be from the same cache problem that DK28 had. If not, then this would not have solved the issues. I now get lock on satellites all the time and have accuracy of 1-2 meters. Thanks for your input.

I have the same issue OP describes. Currently none of what has been suggested fixes it.

You seem unaware Aero is the author and tester of the fix stickied everwhere. And I do not think you understood what he wrote. The unofficial versions of EB13 did have GPS issues. They were diferent than the DK28 problem Aero fixed for everyone months ago. The same problem and same symptoms are now in EC05 except Samsung has removed the user ability to manually purge the cache with ac old start default.

Is ahmgsk the same person as Aero1? This is the only post I have seen that actually fixed my GPS, ever. As a matter of fact, it was from all the way back at DK17. The same steps, aside from being modified for EC05 have fixed my GPS, as well.

This was after over 9 hours uptime. The lock took 2 seconds for the first satellite and full lock on all within 10 seconds. Use of wireless networks disabled. This was not possible before following the steps in the fix. Previously, I was unable to get a lock after 3-5hours uptime. I would have had to reboot.

I did find this post from Aero1. It does not describe all of the steps but, does up to step one on ahmgsk's fix. It does not explain to lock on satellites in any of the startup modes before backing out. it only says enable cold start. That never did work for me (i now remember trying it long ago) and I remember it did not work for many others, at the time. Locking on all satellites in all startup modes and then flashing the update did and does work. It worked on DK17, Dk28, and now EC05.

For all the trouble I've been having with previous Epic's, Sprint gave me a Brand New one. This one seems to be running perfectly. First time I tried GPS, it was instantaneous, and accurate to 1 meter, indoors!!

Did it come with a new battery, headset, and manual?

Weo are you ever confused! ahmgsk's fix is a copy of the functioning part of my fix three months after I published my finidngs on several boards. My fix was extensively tested and worked for all serious posters who tried it.

Moreover I spoke with Sprints advanced device team back in September and they pushed samsung to fix it as we saw in EB13.

You are clouding this thread with irrelevant nonsense.

I have yet to try it on any of the half dozen Epics I have had in a new condition or RTN or reboot when fix was not instantaneous. It isn't really the issue.

Has issue last night when I went to use the GPS.

It worked earlier in the day but would not get a lock this time (waited for 5 minutes outdoors). Near instant lock after reboot.

Please link me to your full fix that matches the entire instructions from ahmgsk. I have only seen your fix in that one post that gets you to the part about cold start (which never worked for me). I see no further instruction in posts that I have seen from you. If you are the one who originally posted the complete workaround, in it's entirety, then I have you to thank for fixing my GPS before and now. I will then link to your original instructions instead of giving ahmgsk the credit. Whether you think it is nonsense or not, that entire workaround has fixed my GPS and it has also fixed the GPS for other users who have had issues with EC05. It doesn't matter to me if you think it doesn't work on EC05. I happen to know that it does. After 5 days, I am still getting instant lock and within 10 seconds have 1 meter accuracy. Other users are reporting to me that they have had the exact same results.

You are posting fud.
It does NOTHING. You are seeing a false positive and most users show it doesn't work. We hae a working gourp on this problem over at XDA and you are not even on it. Are you posting your xtra logs? (no)

Your posts are becoming laughable nonsenese

Yes the same problem is back. We are looking at the logs over at xda. I am testing on four Epics with various fixes. We atre seeing assistance data injection errors in the catlog on EC05 that were there in September but not in EB13!

EB 13 official worked perfect from the get go for me and everyone else. It was only people who had used pre release EB13 who needed a fix, but that was not for a problem with assistance data, but a very different GPS problem causing total non function

[removed by Mod]

xtra logs? I don't know what you are talking about.

Where is the link to your original fix?

Who are the users who, claim that after doing this complete workaround, still have GPS issues?

I originally came to this thread to try and sort my own GPS issues. It happened with an old workaround. I have perfect GPS now and I didn't before. Laughable nonsense? W/E Keep working on a different fix, then. I don't need it. My day of trolling your little tantrum is over.

GPS cache problem workaround, tested, working

It is no longer a sticky since ec05 adn later required a different (root level) fix.

I worked extensively with GPS in the Navy years ago and decided to fix this. My fix was stickied at android central as well. I twas then posted at XDA and other sites

"xtra" is the term used by GPS engineers for the type of ephemera cache used by Epcis implementation of aGPS

The fix I discovered and authored was the number two rated sticky on the phone on this enitre site on GPS right HERE on this site .
