GPS Problems on a new G1

I'm on my third G1. The first one died to some strange graphics issue where the screen would go completely pixilated and wacky on me. I think the graphics processor was overheating. On the second one the touch screen died about the same time the speaker in started buzzing during calls.
Luckly because TMobile extends your warranty 90 days every time you get a new phone, I've only had to pay for shipping. I got the latest one, and immediately installed Cyanogen 4.2.5 on it. No problems. Then I followed Michael Mayhew's instructions for the maps update to get Navigation.
I can't get the GPS to work at all. I've since tried going back to RC29, or the base Cyanogen 4.2.5 without the maps hack. I've tried other GPS applications such as the Chartcross GPSTest. I can't get a read at all on any of them. I don't know if it was working before the updates, because I never tried to use maps before I installed the mod.
So I'm wondering somehow a radio update was applied that broke this phone, or if there is anything I can do to change the gps drivers around. Anyone with similar GPS failure issues?
I don't really want to return this one as I've only had it one day!

Yes, similar issues. No solution thus far. I also did not test GPS before flashing. OOPS?!? And now it no longer works, but I can't tell if that was the case to begin with.
I followed the same procedure (CM 4.2.5, Navigation mod), and had the same result--broken GPS. "My Location" not working, "Searching for GPS" forever, etc.
So two possibilities I can see:
1) hardware problem w/GPS
2) one or a combination of CM 4.2.5 + Nav = broken GPS
I have seen a few people on these boards say their GPS doesn't work all of a sudden. In fact, there are stock Droid owners with issues.
Can anybody chime in?

Hmmm
So for about 10 minutes on Friday it started working again. Totally random, I have no idea why. I was at a party and decided to see if it was working. All of a sudden I had signal (using GPSTest) and google maps found my location.
I've since tried it several times, rebooting, and doing a bunch of other stuff. I can't get it working again. Total fluke! So frustrating!

Well now the new version of google maps is in the market. I've successfully installed that one but still no GPS.

Im having the same issue on my G1 right now. Sorry for the Zombie thread, but did this ever get resolved?

I've had the gps fail on my phone and others I know have also. The g1 seems to have issues with the gps antenna strip breaking internally so one minute you'll have reception, the next.. nothing. Only solution is to find a new antenna strip and replace it (good luck!)

Aside from possible hardware failures, the GPS units on these phones tend to be very weak. Sometimes it *IS* impossible to get a strong enough signal to lock on, even when out in the open if there is something nearby that can reflect the GPS signals.
However note that these are AGPS devices, which means that with a cell connection and a data connection, and given that google knows the coordinates of the cell tower you are connected to, it is able to load assistance data (almanac + accurate time synchronization via NTP), and this will *GREATLY* improve your chances of getting a good lock and greatly reduce the time it takes.

I doubt that it was the GPU overheating. Your phone would burn your hand if it got that hot.
The in-call buzzing could be corrected by shifting the screen a little bit while it is happening. It is related to GSM interference with the speaker. The speaker is literally playing the radio waves emitted by the phone. The touchscreen issue was probably a broken cable... also related to moving the screen.

What radio version are you running?

I've also had no luck getting a GPS signal ever since I installed hacked navigation... I wonder if that's the problem? Has anyone tried removing the hacked navigation, to see if that solves the problem?
BTW, the problem started on CM 4.1 with EBI0 radio (2.22.19.26I), and still persists with CM 5.0.7... Has anyone tried upgrading their radio to 2.22.23.02? How about the folks that have gone back to the Updated Rogers EBI1 Radio (3.22.26.17)?

I have been having the "searching for gps" problem as long as I can remember (although I just got this phone a month or two ago)....I remember trying to install the hacked navigation or something so maybe that messed it up?...this phone was never opened, and I would hate to have to open it up to see if it is a hardware issue because I may not put it back as it was. IDK what to do, I even started a thread about it and tried every solution I could find and nothing worked for me....
I wish someone could chime in here with some insight...but it is also nice to hear others with this issue and their advice/ideas also...
Has anyone tried un-rooting and returning the phone back to complete stock and wiping everything ? has that worked for anyone?

Phone reboots after launching Camera in Android 2,1

Hi All,
I have a problem where my phone crashes and reboots when I launch an app that uses the camera in any way, for example layar, barcode scanner, camera etc. This only happens in Android 2.1, I've tried various ROMs and always the same issue. I've tested Android 1.5 and there are no problems with that at all.
I've noticed the crashes only occur when I'm on battery power, it never happens when the phone is plugged in so I cannot get logs to see what is going on, unless someone knows a way to get the logs from a crash.
I was wondering if anyone else has seen this problem and if so, if they've found a resolution to it.

Since updating with the OTA 2.1 update I have been experiencing this problem too. Phone reboots when it uses the camera, Layar, Yelp, AugSatNav all seem to cause the problem.

I get this problem too, with the camera, and also sometimes when I put the volume down it freezes and reboots

I've got the same problem. Restarting when launching apps using the camera.. Im glad that's not a HW problem but "only" SW bug.. I hope

It could (and probably is) a radio issue....Happens on the N1 and Desire if you try to use the camera too and seeing as the GPS,Camera both are dependant on the radio id say that is it! Find the radio reccomended with the rom you use and flash it( Beware of orange users being locked down though,you need a specific radio)

Just to add that I'm getting the same problem too running FroydVillain 1.2.2 and baseband 6.35.15.14, should point out that been having the problem for quite a while on a multitude of ROMs :-(

I'm not - did you full wipe?

Multiple wipes...

try 1.3 i guess

I had this problem when I was on stock 2. 1 I would recommend rooting and flashing froydvillain.

Tried multiple ROMs and multiple Radios with no change :-(
Unless theres a second secret wipe button hidden in recovery I don't know what else I can do :-/

try to disable "automatic brightness"...

Hi,
I have had this problem since i went to 2.1 also, i have also flashed several rom's since villainrom 12 and have even used rcmix 1.0b which is a great 2.1 imo.
Have flashed 2.2 roms, and i am still having the same problem.
This is how i can replicate this problem and how it occurs, to the letter.
1.Bring phone out of lockscreen.
2.Open camera.
3.Take pic, in dark or light lighting with brightness on any setting.
4.Save pic.
5.Close camera.
6.Lock phone and wait for 10 seconds.
7.Bring phone out of lockscreen.
8.Open camera.
9.Phones lights all go out and the hero name flashes up onto the screen.
10.Full reboot.
This happens everytime no matter what.
Some things to consider.
The phone will never reboot if it is plugged in to a usb / electric plug Charger and is actually charging.
The phone will remain on and will carry on taking pictures IF you don't close out of the camera the first time around.
No task killer was installed on my phone at the time of this test, although i have had task killers before with the same results.
Lighting effects and brightness can sometimes have an effect on the ratio and probablility of a reboot, with brightness on full in a dark room being the most probable.
I am using the newest froyd rom 1.4.3 although i have tried pretty much every rom out there, I NEVER have this error when i installed a 1.5 rom which does not have apps2sd (weird that) which tells me that it is NOT a hardware fault.
I am using villains no logo kernel 19mhz - 691mhz
63.18.55.06PH_6.35.15.14 Radio
HTC Hero on Orage UK.
IF anybody can shed any light on this rather annoying matter resulting in this problem being erradicated will earn my eternal respect and a big clock. : )

I can confirm that this isn't a bug on every install of 2.1 or 2.1 as I am unable to replicate the issue as described. Also if you've tried mutiple software and the bug is occurring across many that would suggest it is something hardware related or you are not performing a full wipe. Have you tried backing up the data on your sd card and formatting that then putting back only the necessary data (pics / music etc)?

I originally posted this issue and the descriptions from everyone else with the problem match mine pretty much perfectly.
I've taken all info off the sd card and performed a complete wipe of data, ext and davlik before formatting the sd card. I've put the blank SD card (apart from the ROM I'm about to flash) back into the phone and flashed. After config and before any new apps are installed on the phone I launch the camera and within 4 attempts at start the camera the phone will crash. This has happened across every 2.1 ROM I've tried, but doesn't happen on 1.5 ROMs.

Using the stock camera app? Have you tried without installing any of your own apps at all?
This is very odd. No matter what I try I can't get the camera app to crash. Though I am using v2.2 of android. Have you tried official 2.1? Vanilla and Sense?

Yep, it crashes using the stock app.
I've tried a rooted version of the offical but not the actual OTA update. I've not tried vanilla as I don't really want to run vanilla on it.
I've managed to take some logcat logs of the problem happening but there's nothing really specifc happening over a few crashes that would point to anything. .
I'm going to try to unroot my hero and downgrade to stock to start again. Just have to find a way to downgrade my bootloader first so I can put on the original RRU. I tried to downgrade before but got an invalid bootloader error.
The camera crash doesn't really affect me day to day as I don't really use the camera, where it is annoying is it stops you using apps that use the camera like goggles and layar.

Ahh - so its not the camera app that is crashing but other apps too which are using the camera. Very odd.
And FYI - you don't need to touch your bootloader - just change the driver in windows to My HTC instead of HTC Bootloader and the rru will work.

I have formatted and re partitioned my sd card to a T and it still occurs and thats with everytime i install a new rom, i don't use titanium i go the long way around every time and re set up all my programs, I know i can replicate this error like i said and like i also said this does not occur in 1.5 roms.
I have also have this problem with vanilla, modaco's new one, villain rom, rcmix, froyd, it appears that ever since the phone was updated to 2.1 there is a problem when using the camera app.
I have tried to install a rom and replicate the issue without installing any apps at all and it still persists, the only thing i can say is that it doesn't happen when i'm either on 1.5 OR the phone is charging?
It sounds like the the phone is requesting access for use of the camera and then not putting back what it requested in the first place, like a cache or something, and it simply make the phone reboot when it is called upon again.
I don't believe it is a hardware fault, i know this sounds like wishful thinking but the phone does not have this error in 1.5 roms. Thus, it cannot be hardware. Simple!
Also a logcat does not show anything, i was only able to replicate the error once whilst my phone was plugged in, it just won't do it again, and when i posted my findings on villainroms bug report section, a few of the lads still didn't know what it was so i don't know what else to say.
I'm due for an upgrade in October so for me at least it's not that much of a deal but i'm planning on giving this phone to my daughter so it would be good to get it working for her.
Would save me a lot of earache.
If u need to know anything else then please let me know, oh and i am using a class 2 sd card, which i have been unable to change, however just today my girlfriend has just had a class six delivered and her old one will be up for grabs so i will test with that too. Has anyone else tried with multiple cards??? Also how do i find out what boot loader i am using (recover) as maybe the problem resides there.

Thats right, its any app which accesses the camera.
What could be the correlation between connecting the charger and not connecting the charger, could that be a power issue and the battery is delivering too low a power output on it's own to run the camera? Hence it works with the charger plugged in ?? Either way i think that is the only real clue there is to be honest, unless your phones still restart when the phone is plugged in, in which case it's not much use.

How to solve phone unresponsiveness after using GPS??

Hello everyone, i've my SG3 flashed with Gsam101 ultraclean SPF rom + modified JPB kernel + lagfix v2!
I've solved the GPS slowness using the post http://forum.xda-developers.com/showpost.php?p=10385614&postcount=43
The main issue is that opening googlemaps already slows down the phone (cause it's kind of heavy application!) then with this software glitch it becomes even more slow... it's a sort of 3310 with froyo on it! :-(
I've kind of few applications installed btw and NO services started at boot, so i would exclude the cause of 3rd party applications causing this...

Did you actually fix the unresponsiveness? Or just the GPS fix time? I've managed to get the GPS fix to work, but the phone becomes very slow, even after the GPS is turned off.

exactly my problem, the gps fix with the method posted before is really fast!!
The phone becomes slow though, as you said :S

Ok I think I've found the problem. The stock GPS I5800XXJPF actually works really well. With a fresh install, my GPS would lock on for the first time within 20 seconds or so, and the phone would work fine. However, after reinstalling all my stuff with Titanium, the GPS went back to being very slow, and the phone would remain slow (laggy) until reboot.
So... I checked my GPS settings and I had 'Use sensor aiding' checked. Unchecked it, reboot and voila! No GPS problems. I still use GPS toolkit to make the first fix, but that is the only thing different from stock. GPS works great now and phone runs at full speed.
Does this make a difference for you guys?

You're my new hero...this "fix" works and gpsfix it's still fast and stable!

disabled "sensor aiding" on Galaxy-3 i5800
Hi,
I was planning to make a new thread on the lagging behaviour of the galaxy-3 i-5800 when i found this thread.
problem I had for long time :
My phone went to 100% cpu after "closing/ending" an application which uses gps, like g-maps,copilot,lattitide etc. It took me many weeks to pinpoint the problem, when it happened. Reason it took so long is that i found by accident, the 'remedy' , which is switching off the display and switch it on again. This interfered with the root-cause analysis , because when the screen went out automatically, the problem dissappeared :-S
"Finally" yesterday i found the root-cause of the lag.
It was "sensor aiding" in location and security setting. After disabling this setting, the lag problem is gone.
In dutch the setting is called "sensorondersteuning", which is located under "locatie en beveiliging".
So I want to spread the word to many galaxy-3 owners (i-5800/5801) to NOT use this feature (even not in the lates JPM firmware).
From yesterday, I'm a happy galaxy-3 owner again
enjoy it.

its JPF not SPF and its kinda stock like, many stock apps are removed, social hub etc. I dont think any are added, besides superuser since i suspect its prerooted

Android GPS Issue!

Now we have so many great Android ROMs for HD2. However, I have yet failed to find a ROM that has GPS working completely. Some RoM has GPS locking issue, other locks but freeze so many times. lets face it, we are driving, we are on the road, and we are lost, and the next thing you want is your GPS stop working on you in the middle, taking the phone out of the case, and pulling the batteries, and waiting for it to boot up again, probably by then most of us has left our destination about 10 miles away.
So in this thread, I want everyone to list the ROM that has the GPS working completely.
Thanks,

move to question forum. AGPS is not working yet, thats why there is the GPS issue

I have never had GPS issues with any of the Android ROMs I have used. Occasionally when using IGO8 I have had the phone reboot but this was only minor. See my sig for the ROM I am currently using without a problem. If you still experience issues then I suggest you try removing any additional programs you installed as they may be causing conflicts. You don't say what navigation program you use as this could also be a problem. In addition to using IGO for car navigation, I also use MM Tracker for hill walking so I always make sure that I fully test GPS on any build I use as I could end up lost on a mountain!

Try Typhoon ROM with the GPS fix .. without GPS fix it takes as long as 10 minutes but with the fix its as fast 15-30 second .. I've been using for over a month and haven't had any problem. Battery and Bluetooth is unbelievable. And I do agree that at this point if it freezes up its probably some apps that cause the problem .. not the ROM itself. G'luck!

GPS losing signal, heats, freezes, drains battery

I've been using HyperDroid rom for a long time and been having issues with my navigation software for a while and I'm not sure what the exact problem is.
I'm using iGO My Way and sometimes the GPS will work fine for a while and then a lot of times it loses signal after about 4 minutes and won't lock back on until I reboot the phone and restart the program.
Then at other times the phone gets hot and will just freeze.
I also noticed after these things happen it won't help turning the GPS on/off, it will keep draining the battery even if I turn it off. I always have to reboot to get everything back to normal.
So I don't know if the GPS module is bad, or if it's not a good idea to use iGO.
I haven't tried using other navigation software since I need an offline one with maps of Israel. I don't have a data plan.
I did use SportyPal many times in the past for cycling with GPS and it never froze.

Try to use Sygic for a week...with this one I doesn't had any of your issues since android was given to our leo!

Hey thanks! I gave Sygic a try and the GPS actually connects much faster and so far I didn't lose signal in the middle. Also the phone doesn't get as hot as with iGO. It only froze once, but I'll keep testing it. It's much smoother and faster than iGO though.

Well, sadly, I lose signal with Sygic also...
I don't know what the problem is :/

Sygic
i have been using Sygic from quite a while now. It does not works well with few of the ROMS.
Currently i am using American Android 2.3.7 and it works like a charm for me with it.
Which ROM are you using ?

HyperDroid 5.8.0 but seems like no one else is complaining about GPS issues.
Could be the radio version (2.15.50.14) or maybe the GPS module on my phone is defected...

chance your rom
You can change your rom bro.I think you have to
Because radio is not problem 2.15....... is very good.I am using same radio,but different rom.I havent problem with igo or sygic

Yeah but I like HyperDroid. It's fast and stable!
I'm waiting for the ICS roms to get better... then I'll probably switch.

Hello
Sorry for bumping this but I have exactly the same problem. This has nothing to do with Sygic. The problem can arise with any application that uses the GPS and fails to shut it off properly (at least that's what I understand). From the moment that this happens, the GPS doesn't work anymore, heats up the phone and drains the battery fast. The only way to get it back working is to reboot the phone. Turning the GPS off and on, doesn't change anything.
I had this problem since 2.3.7. I had found a kernel update that had fixed the problem in that version (dorimanx's kernel but I can't remember the version) but since I upgraded to ICS and now JB the problem came back. With JB it works much better but it is there. With ICS it was a nightmare. I have tried many (over 10) different ROMs and each and every one of them had the problem. This is something that has been around for ages and nobody seems to have found the real cause or a remedy. I'd love to cure it since I love my HD2 and it's the only thing that is marring its performance. Have you had any success with it?
Regards
George

i to have had this problem and i find it to be a rom problem will work ok for a hour or two then have to reboot the phone the only rom i seem to get it to work ok are the old gb light roms its about 120 deoxd

Had the same problems with most of the sensation or other sense Roms. The problem is solved since i use 4.x.x Roms as dataonsd installations. Now googlemaps works like a charm. Love the traffic info
