Do any of the cognition versions have a gps fix?

I'm running the stable cognition 2.1 version.
Or do the 2.2 cognition versions have a gps fix in them?
I hate running beta versions which is why I'm not running 2.2.

There is no real GPS fix that I know of. You can play with the lbstestmod to try and improve performance.
Captivate
Cog 2.2

Latest CoG version runs great.
GPS works well in the car but you need to have in a dock on the window. If you have it on the chair, wont work, it will tell you that you're in Moscow

None of the 2.2 versions have any modifications for GPS. Some of the earlier 2.1 versions did, you can check DG's download page and the change log shows whats in each and when he removed the "fixes".
I have had better luck with the 2.2 versions but Im on my 3rd captivate and I can say that my 1st one sucked in comparison with me 2nd and 3rd. My first was just a lemon, I hosed the second and got a replacement as the 3rd. The only setting that has seemed to make much of a difference for me is going with cold start versus hot start but that could just be me and what I "think" helped.

If you have a phone with a working 3 button combo, try shep s rom based on the jpm i9000 build. Gps could lock in my living room and locked/tracked well while moving. The reason why I mention the 3 button combo is for some reason, that rom does not let you into down load mode with the vol + plugging in usb so you could perma brick your phone.

Well, it works for me

Yes and no. Froyo has decent performance but soema are haveing problems. I personally see a problem if i leave lbs test mode running too long. Lbs can get a lock better than google maps. So sometimes ill use it first if i have troubke getting a lock. But it will turn the gps off after some time on my phone( icon disapears feom notification bar). After that i see the chip turn off at a regular interval in google maps. Some software works without a hitch like my tracks. Some seems to cause a similar problem. And some is touchy. I might sugest trying an alternative software like navdroyd. And if you dont get a lock at first just be patient. The error on my phone doesnt seem to be universal and only a factory reset fixes it. Still i dont recomend changing the lbs settings just incase. If you dont get a lock go outside with a clear sky and let it try for at least 10 minutes. In google maps you will need to prevent it from sleeping so you might want to try an alternative program. Once you get a lock you shouldnt have trouble getting another one. But some are still sating they have poor gps. Either there are alot of negafive people or the gps performance is inconsistant. It may just be a hardware issue. For navigation in your car you might want a bluetooth gps antenna. The phone should otherwise work for walking around.
edit: i have no dificulty navigating in my car with no accesories. Even with the phone on the pasenger seat. Other than the one error which i have been able to prevent lately my gps works great.

My GPS is fine if i give it a pretty much vertical view of the sky through the windshield. If i set it on the passenger seat or in a cup holder it performs terribly.

This should have been asked in the Roms thread instead of opening a new thread.

[APP] 50% time without a signal fix - 2/2/2011

App: xtr50fix Android 2.1 only.
I made this app to try to help those with the 50% time without a signal issue. Learn more here ( http://forum.xda-developers.com/archive/index.php/t-647980.html)
The one trick that works with most 2.1 Eris ROMs is the airplane mode trick. All you do is put your phone in airplane mode for a little bit and turn airplane mode off and it fixes the issue.
Basically all this app does is upon boot, puts the phone in airplane mode then waits 12 seconds and then turns off airplane mode. Finally, it kills the service so it won't run again until the next reboot.
I know it's not elegant or anything, but it seems to do the job. There are no settings and there is no icon for the app. Just install the .apk and reboot your device.
Please let me know any feedback you might have... good or bad. Thanks!
2/2/2011 - v1 - Initial build. Seems to work fine on xtrROM and xtrSense.
Added some checks to make sure you are not already in airplane mode upon boot.

Sounds interesting, thanks! I just went back to xtrSENSE so this is perfect timing.

has anyone tried this app yet?

Yes, that works as well, however, you still have to do that every time you boot up.

This seems to have worked on my optimus v. Thanks for your efforts!
Prior to this, I was constantly getting the 50% without signal mess...

Works perfectly on my Optimus V. Thanks so much for developing and sharing this fix.

Thank you lotus22! This has been included in the latest release of xtrSENSE http://forum.xda-developers.com/showthread.php?t=726467

Would this work on a Droid X? I get that bug and I'm rooted with stock 2.2.

I'm only replying so you don't feel ignored. No idea, myself, but can you do a nandroid on the X and try flashing this to see? You might be the first person to try, so you can let us know if it works!
For the record to everyone, this seems to work just fine with Gingerbread ROMs, too.

Lol appreciate it! Unfortunately it didn't put my phone in airplane mode when it booted back up.

I don't have a Droid X to test on... however, I did compile the program with the Android 2.1 SDK so it should work on anything with >= Android 2.1
Note: Don't flash this program. Just install the .apk like normal.

Thanks Zach! Glad you included it. I bought a Motorola Droid off my friend so I don't use an Eris for my main phone anymore. I'll have to test this out on my mom's Eris which uses xtrSense!

This app fixes the 3G drops with my Optimus V. If anyone is looking for automated reboots in order to automatically apply this fix every day, I use Phone Prioritizer.

Thanks for this. Hopefully my battery life increases.

Can someone tell me how to install the fix on an Optimus V? I tried downloading it directly and I get a message saying it is unsupported. I also tried installing it from gmail and it didn't work either.
I am about ready to return the phone if I can't get it to work.
Thanks,
Paul

Make sure in settings->Applications-> you turn on Installing Apps from Unknown Sources.

TWS/data drop fix
The fix50 app did fix the TWS problem on my optimus but didn't seem to do much for the battery or fix the data drop issue. I ran across this fix posted by greenmonster on an Android Central forum (http://forum.androidcentral.com/optimus-v/57943-excessive-battery-drain-even-standby.html):
To fix the issue, dial *#*#4636#*#* and it will load the testing screen. You do not have to press call. Select phone information.
My understanding of the bug is that even though the preferred network is set to "CDMA auto (PRL)", it is actually set to "GSM/CDMA auto (PRL)" because of a display bug.
The fix is to press Menu and then "Select radio band". The process will then force close. Go back to Phone info and select "CDMA only" and then select "CDMA auto (PRL)".

I'm going on day 3 now (no reboot) and have had a noticeable increase in battery life an no data drops that require an airplane mode toggle. Any way this might be made/incorporated into an app similar to fix50?

Data drop/TWS update
So I finally had a hiccup about 9:00 last night that caused a data drop- it was right after I lost a phone call & during a pretty serious storm, so don't know if that affected anything. I'm still pretty happy- I've never gone more than three or four hours without having to do the airplane mode toggle due to data drops- 60 hours without a drop is encouraging!
Time without signal also stayed in the single digits...

Installed and working on my Captivate running Froyo. Good stuff.

[Q] Camera App Freezes on Click

Recently after upgrading my CM7 version to the latest final build. The camera app hasn’t been able to take a picture. I would click the button to take a picture and then it just freezes the app and I have click home to get out of it.
Any Ideas on what might be causing this? I really don't want to have to wipe the phone as reinstalling and syncing everything takes too much time for me and I have finals coming up and can't have my phone not with all my info for more than a few hours due to a business I am setting up

Wipe only cache and reflash the ROM, that *might* do it.

Yup I agree. Also it might be a bad dl zip. If what duce posted doesn't work try just redownload the zip, do a full wipe, and flash away. Id also try reflashing your recovery it might help.

thanks guys, il try those and get back to you

CM7 GPS - no lto.dat?

Hi,
after spending some fruitless hours trying to get better GPS performance from my p990 (cm7 nightly 60-64, baseband 0218, cm7 RIL), trying various tweaks to gps_brcm_conf.xml and even older versions of glgps, I've concluded (tentatively) that
- /data/gps/lto.dat is a file (containing ephemerals?) that's used for A-GPS
- my setup never manages to download this file.
Following this thread of thought, I tried the following (The URL is from a google search while I was digging about in gps_brcm_conf):
Code:
adb shell
cd /data/gps
wget http://gllto.glpals.com/7day/latest/lto.dat
chmod 777 lto.dat
I also did
Code:
rm gldata.sto
to remove (I think) stored orbital data from previous fixes to try to keep the results comparable.
Though measuring GPS performance is difficult due to constantly changing constellations and atmospheric conditions, I think this has made a difference in time-to-fix for me. Admittedly this might just be a placebo, so no guarantees.
If anyone wants to try this and post their results, it'd be great. And, if anyone knows anything about lto.dat, why its needed, and why it never gets downloaded, please post here so I won't be kept awake at night wondering

It might be that the Tegra2 setup doesn't use it, much like gps.conf.
Best bet would be to ask RC I suppose, although he's a bit tied up with some GPL stuff apparently.

It's referred to in gps_brcm_conf.xml (the chip-specific config file), so I've assumed it's relevant to our setup. But yeah, it's possible.

Yeah, I'll hold off on that a bit.
Would be interesting to know if anyone actually has that file in /data/gps. I'll try to find time for a restore to stock (or at least modaco) to see if it gets downloaded in the standard setup. We'll see.

don´t have it on cm .64 either ...

Just created the missing file, and got a lock from stone cold, indoors pretty fast. Did that file help? Dunno lol
Will have to test more.

OK... here is my extremely unscientific test...
GPS Status without lto.dat: 43 seconds to lock.
GPS Status with lto.dat: 19 seconds to lock.
aGPS data was cleared before each test. Interesting, but far from conclusive.

Whooo! This is amazing!
Tried to lock inside without lto.dat, no luck at all after 70+ seconds... Copied the file into /data/gps, tested the same spot and got lock after cca 10 seconds!
This is amazing

Good find. That file basically holds an analog to XTRA data; It doesn't quite help picking up satellites, but it makes locking onto them a hell of a lot faster once they're found.

It wont, that's just how Android works... my stock N1 was the same.
Endomondo excepted, that should be able to hold a lock, but doesn't. Run Keeper does it fine though.

It's a pain, and odd the Endomondo can't do it, when others can. If they all couldn't it would be an obvious problem, but when it's just that one (the one I happen to use at that) it's frustrating.
Still, as you've noticed, there is a work around, this might be less hassle than having My Tracks going though: https://market.android.com/details?id=com.kaukovuo.android.trackerbooster

lto.dat works great for me !!

Since a few days i have to switch wlan on and of twice after lockscreen to make it work.

Did you change ANY settings? Like undervolt, overclock,... Maybe installed any "battery saving" apps? Such things might cause such behaviour. Make a nandroid backup, then do a full wipe, test again. If it doesnt get better, well I dont know what s wrong... If it does work again, you can restore your backup and try to find out, what's causing the problem
