Let me start by saying my Mogul (Bell) has ALWAYS LOCKED (found satellites) with ALL of DCD's ROMS from the day he started creating the ROMs for the GPS. All the "GPS" radio's have worked and am lucky never to have a problem except one: Not Finding GPS/Satellites after the Mogul Sleeps or being able to get it working again without a soft/hard reset everytime!!!
I have been using only DCD's ROMS and currently have radio 3.35.04 and DCD 3.01 installed. I am using Garmin XT and GPS Tuner. I get the same results with every GPS software I have tried.
Here are brief details:
After hard/soft reset - if its within a few seconds and I catch it quickly, there are no problems, both the AGPS and the software are working fine.
After 2-? Minutes - if I let the unit go to sleep, and awake it via the Power button, the gps program is looking for satellites. Sometimes it finds them, most of the time not. It wont find them in ANY program, even GPS Viewer and/or any other navigation program.
After Many Minutes - not only are the satellites gone, but now the navigation software cannot find the AGPS with any program OR method.
Sometimes a soft start fixes it, sometimes only a hard start will do the trick.
I have tried as much of the "forced start" software that I could find, but to no avail.
I also changed the com port to 5 thinking that there maybe is a conflict with 4, (you have to make sure the com port setting in all of your GPS software is also changed unless the software does this automatically) but the SAME issues stated above occur.
I have loaded and reloaded probably 20 different configurations of my software even to the point where all I had loaded was the bare DCD rom (no options or unnecessary OEM's) and JUST my Navigation software. Same issues......
I hope I am not the only one and hope that the contributions to this thread will fix this issue.
Please.....Keep this thread focused on this issue only - Keeping the GPS alive!!! ( no Where did you get this or that program? How did you install it?)
keeping the gps alive will kill the battery.
yea, i have teh same issue as you. soft reset is the only way i get gps working.

Maybe a better way to phrase it would have been to make the GPS available without having to do a soft reset every time.
We don't want to keep GPS alive indefinately! We just want so if we accidentily press power button while navigation is happening, we not have to reset the phone.. because this is a little inconvenient. If I am driving down the road and I hit my power button, now I have to pull over and reset my Titan because otherwise I have no GPS navigation ability and that's not a good happening, you know? We just want so if navigation software is active, not kill GPS, then when shutdown GPS navigation software, shut down GPS gate properly so when want to relaunch GPS navigation software, not need to reboot Titan.
I'm sorry to post in a rather old post.
But I'm having the same problem with my Samsung i780.
When I already used my GPS after turning on my phone and put it back to sleep, it can't find a valid GPS signal when waking it up.
After a soft reset, the GPS signal is found very quickly.
Any fix for this?
yeah, the fix is GC's aGPS fix. I never have to soft reset my device to get a lock ever.
I don't use aGPS, just the internal GPS receiver.
Will it also fix the problem then?
>> edit:
It's not that the GPS doesn't work after accidentally pushing the power button. It's more like when I use the GPS the first time after turning the phone on, everything works fast and good. But when I close the Navigator software and turn it back on in -let's say- two hours, it doesn't get a signal from the GPS. I don't use aGPS.
I only use Google Maps and TomTom7. If I make sure the phone doesn't go to sleep while Google Maps is tracking GPS all is fine. However, if the phone goes to sleep while Google Maps is using the GPS it will not work again, in any program, until I soft reset. If I bring the phone out of sleep fast enough, it's fine. If the same happens with TomTom though it takes a few seconds to fix itself and then everything works just like it did before.
I'm not sure why it works fine with TomTom and not Google Maps though.
I found that if I use the GPS toggle program and leave it on. It finds the GPS signal after sleep mode. It is a small today screen plugin. I also have attached the latest version of Google maps. If i am using the GPS with Google maps it doesn't stop when the phone goes into sleep mode. See if this helps.
i use the same gps toggle program that tommvee suggested using and it works great. i wasn't originally having problems finding GPS satellites after waking from sleep mode, but was having to wait up to 5 minutes before garmin xt could find my location. after installing the gps toggle .cab, doing a soft reset, activating the gps toggle and letting it run in the background for a few minutes, both garmin xt, and googlemaps can now find me in about 30 seconds. i do believe however, that you'll have to reactivate the gps toggle after restarting the phone but it will stay running while your phone is in sleep/standby mode.

Is there anyway to activate the program without the today screen plugin?
I'm using the default Samsung Home plugin and it takes the whole screen...

I am also using aGPS but still have problems if I accidently hit the power button in Google Maps and forget to turn it back on. My power button is very sensitive so even brushing it as I set the phone down will put it to sleep. It doesn't click anymore like the other buttons do :/
As for the battery usage, I only use GPS in my car where I have the phone plugged in 90% of the time.
Where can I get GC's GPS fix?

I think there's a link to the How To in the Titan wiki.
Any pointers on shutting down the gps gate? I could try a utility for doing the shutdown manually.
hey im wondering if this would work for us or is there some porting needed and is this somthing that would help gps and if im in the wrong section please move.

Very interesting post indeed.
From his findings, I'm also wondering if we have Auto Rotate Screen (the accelerometers) turned off, if that hinders the ability for our GPS to accurately detect location and movement. He suggested that it goes into low-power mode when it isn't detecting movement via the sensors, but didn't say what happens if the sensors are turned off.
...I'm going to have to test this out tomorrow.
Are people still having issues with GPS on the fascinate? Since we more or less had the issue fixed I've had as good or better GPS performance than on my other smartphones.
Da_G is a good buddy of mine, trust me, if anyone knows wtf they are talking about, it would be him....

im just wondering if this is safe to flash to our phones or does it need to be ported to fascinate
yep still having issues with gps...sometimes doesn't lock. sometimes takes forever. sometimes...omgsh...it actually locks!
not reliable.
I applied the d101 gps fix to eb01 and my gps locks in around 20sec. Auto rotate or not my gosh never locked on eb01 without the d101 fix.

Just tested my gps a little. Mine is locking within 5 meters in a brick building with auto rotation on or off. Not in a car currently but I took a little jog and it seemed to follow my direction and location very accurately in both.
So I guess my GPS is pretty good.
Regardless... I wanted to say thanks for reposting that because it was a really interesting read!
It should just work, even though EB01 stock should just work too.
Just don't flash the AT&T-specific version...
The Fascinate doesn't seem to have the same layout concerning the gps jupiter files (I don't see them anywhere, at first glance). Either I am missing something or it's a completely different setup.
There are some settings in his /data/gps/secgps.conf (just a text configuration file) that are different than the stock fascinate file. These might be worth looking into to see if they help improve the signal without using his modified binary. You don't need to flash the file using CWM, just use adb to push a modified file (or root explorer and edit it on the phone itself).
Since this is a CDMA phone, I don't know how many people this would affect, but here is a general Android GPS tip for those who don't live in North America:
In /system/etc/gps.conf, change the address to the server that corresponds to your country:
Code:
NTP_SERVER=[COLOR="Red"]north-america[/COLOR].pool.ntp.org
I usually can't get an accurate lock or any lock at all unless I reboot with gps already enabled. Then I will get a good lock instantly... If I reboot the phone with gps off then I will get no signal/lock again.

Let me share my experience with GPS on EB01, it's GREAT, you just have to turn on GPS "correctly."
If I turn on GPS using the Notification switch, GPS takes FOREVER to lock, if it even does so. Gone several minutes with no lock.
Now here's the thing, if you turn on GPS in the Settings > Location settings, I always get super fast, under 5 second GPS locks. ALWAYS. I've tried this out repeatedly over several days, and it really makes a difference. Once you turn on GPS using Settings, you can leave your phone on, reboot, whatever, and GPS will still be responsive. If you turn it off, wait a while and use the Notification switch to turn on GPS and you're trying to get a cold lock, it'll be slow again, just be sure to use the Setting option and it'll be back to being responsive.
That's my experience.

Nice observation...just worked for me too!!
By golly... He's right, although it took me about twenty seconds to lock.

Hmm... I remember this from a different android device I have. The stock power control widget for wifi would take 45 seconds longer for the network to connect then if I would go to the wifi menu and turn it on myself. I found out that there were two methods for turning on the wifi programmatically, and that some widgets used one method and the other widgets used the other.
If I remember right, the fast method changed the setting by calling the wifi menu and emulating the menu press, while the slow method attempted to power on the wifi directly.
$10 says that if you started decompiling, you'd find a similar situation here.
Hi, I'm currently using ICS Passion v10.6. I do not have a data plan, but am always connected to wifi at my house (router is usually about 3 feet from my phone).
Often my phone will lose google connectivity (wifi and signal bars will go gray), and often, usually when i leave my phone untouched for a while and then check it, i will notice that wifi had been lost and it does not reconnect until i turn the screen back on. I have the wifi sleep policy set to never sleep (keep wifi on: always), and the battery info says that the wifi is constantly on.
I was wondering if a different modem would help or if it is a bug in the rom itself or the kernel? My wifi and google connections would constantly be on 24/7 when I was running bionix v1.3.1. I've tried flashing the KB1 modem which bionix uses, but i get the same result.
Thanks for any help
Hey Devils,
I've had some of the same issues, aslo using 10.6. If I leave my phone alone for a bit it seems to stop getting notifications from data. The best example of this is I use Trillian IM and I can be chatting on it. Finish. And put it aside for awhile and not get any notifications and then when I hit the power button all of a sudden I've got 30 IMs waiting for me.
I have tried several different Vibrant ICS modems from this thread but they all caused big issues for me. some caused massive power drain but all of them caused my lock screen be unresponsive when I hit the power button and I'd have to wait for the screen to blink out and hit the power button again to be able to get access. The same would happen when I get a phone call, sometimes the screen just would not respond when it lit up for an incoming call. I think it was because it would start searching for data connectivity (so it seems related to the problem which makes me think it's not modem related)
In the end, I went back to the KB5 modem and my screen issues seem to have resolved. I may try Passion 11 soon and I'll post results if it helps, but right now I'm not ready to do another change on my phone.
-update- I just checked and saw that v12 is out now and has both a kernel update and an update to wifi. I'll probably try that tonight.
-update- I think this might be being caused by "Deep Sleep" causing the phone to shut down it's data antennas to turn of to save battery. I've installed "NStools" on my phone and set it to set the min CPU freq. to 200mhz to see if that will prevent deep sleep. I'm not certain this tool will work 100% on this build, but we'll see I guess.
I'm also running the Vibrant without data, using wifi to do things with the internet.
Since flashing ICS I haven't had any wifi issues on the two networks that I've used. Seems odd that you are now having them. Have you tried a different hotspot?
I have had issues sending text messages. I can place and receive calls, receive texts but can't send any. Have you had any of these issues? I'm curious if it has to do with the lack of data plan.
I posted a question about this last week thinking it was a wifi problem, but it turns out it happens when I'm on data too, so it's an overall data problem... I'm just using wifi most of the time so that was the only place I had noticed it.
Occasionally my phone will stop being able to send/receive data. I'll turn it on and try to load a web page, for example, and it will just hang. Turning wifi on/off doesn't fix it, and turning data on/off doesn't seem to fix it either. The only solution I've found is going into airplane mode for a second. The frequency varies.. it seems to happen between 1-5 times a day, so it's pretty inconvenient.
I've read around a bit and it sounds like it's caused by the phone trying to get a 4G connection but it isn't able to or something, so it just hangs there and never lets the 3g/wifi connections get used (due to priority of connections or something). I almost always have wifi and don't care that much about data speeds, so if disabling 4g altogether would fix the problem I'm game (although I'd prefer another solution...). I tried the *#*#4636#*#* code to change it to GSM only (I read somewhere that that'll disable 4g), but it instantly reverts back to what it originally was, so that doesn't seem like it'll work. Is there another way to disable 4g?
I've got the stock ROM running Entropy's latest DD kernel.
I've had this same exact issue while running Miui and the Siyah kernel. What I've narrowed it down to is likely to be some sort of power save mode that kicks in when the phone goes into deep sleep mode. I haven't had the issue since I've ran the Kernel cleaning scripts and reflashed the latest Siyah kernel, but it reappears occasionally. On certain releases of Siyah, I've ran SetCPU at a minimum of 200Mhz to keep the phone from going into deep sleep just so it wouldn't turn off the cell radio.
Also, as a side note, I've had this happen when my phone loses signal. After so much searching, it will turn off the entire cell radio and display "Emergency Calls Only" until Airplane mode is toggled.
I had this same problem even back with my Captivate. Hoping ICS won't have the same issue. I'm running CM7 and Siyah kernel.
I am having the same problem Data wont work until i turn airplane mode on and off
I am having the same problem Data wont work until i turn airplane mode on and off.
Have you found a resolution?
Every once in a while I get an issue where the wireless driver on my phone will crash. In the logcat it says Wifi Driver failed to load. This is after it goes to sleep I think. But it won't turn back on afterwards. The settings app will proceed to freeze while trying to open up the Wifi list or it will show the Wifi list but it'll be a blank page and you can't switch wifi on or off. I usually have to reboot the phone to get wifi working again but sometimes I can do a quick settings toggle on it. Anyone else get this issue? This is only on AOSP roms, the Touchwiz roms work just fine!
