GPS won't lock on!! (FRF91)

after updating to froyo using the official OTA EPE54B - > FRF85B - > FRF91 my GPS will no longer lock on in the Google Maps application.. its pretty frustrating has anyone else experienced this and/or found a solution? I feel if it was a widespread issue their would be a big post about this already but I wasn't able to find much when searching the forums any help or advice would be most appreciated!

I have the same problem. I made a thread before but no one responded. Here's what I posted before:
Whenever I use the navigation feature in Maps, it gets stuck on "Searching for GPS." I've left it like that overnight and nothing happened. The entire time, the GPS icon in the notification bar is blinking. I've downloaded the GPS Status app and it can't seem to be able to find my location either.
I've tried wiping everything, installing different roms, reinstalling the radio but nothing seems to be able to fix the problem. Navigation worked fine before. This problem just popped up out of nowhere. I've tried it when I'm outside, in different cities, but that hasn't helped.

I also went back to 2.1-update1 to use the older version of Maps but that still didn't help. I've tried searching for others with the same problem but no one seems to have found a solution yet. I don't think it's a hardware problem though since people with different phones have reported the same problem.

I actually had the same problem with my previous phone which was the milestone (aka Droid) and the problem just randomly resolved itself.. so for sure I agree it can't be a hardware bug just wondering where the problem could be coming from then since by your findings it doesn't seem to be OS specific since your able to reproduce it on 2.1 as well.. and your also saying a factory reset doesn't fix the problem, so that rules out 3rd party apps.. I read on some other forums that some ppl had similar problems with the G1 and some people reported a battery pull as a temp fix. I tried it but it doesn't seem to make a difference.. have you tried this? also is the problem intermittent for you? or has it just stopped working and you haven't been able to lock on since?

just did a factory reset and still the same thing

no one has anything I could try to attempt to resolve this issue ?

Happened to me. Fixed itself in about 4 days.

im having the same problem since FRF50... my gps is slooooow and inacurate... ive tryed everithing, changing radios, several wipes, flashing all kinds of roms and backups... still the same...
when im in my house, the blue triangle appears at my neighbors house!

When I first got my phone the GPS wouldn't seem to get a fix (OTA FRF91, totally stock), but it essentially fixed itself. I took it outside and let it sit for 5 minutes trying and it eventually did get a fix, and now it gets fixes quickly like you'd expect. I should note that when I got to to make the first fix I had cell tower assist turned off.

Happened to me in FRF83. Went back to CM5.0.8. Started working again. I am on CM6.0 RC1 (based on FRF91) and it is working without a problem.

I've tried that too. I've had the problem for almost two months now but I never had it before. It's really starting to get annoying since none of my other apps can detect my location either [weather,news]. I hope it just magically works again some day like it did for everyone else.

could this possibly be faulty hardware? should I try sending it in for a swap??

[FAQ] O2X Shut off

Why my LG Optimus 2X freezes and/or reboot?
Most of us have the same problem, we are trying to find a solution. In the meanwhile we can solve only removing battery.
Is it related to baseband version?
It does not seem related to baseband version. The problem is present in last baseband versione too:
1035.21_210110405
FRG83G
V10b
Is it related to ROM Version?
Apparently it happens on both stock and custom ROMS
I read that it is due to wall charger problem
Some of us have the same problem recharging both from USB PC and Wall Charger
I read this is due to overheat problem
Some of us still have the problem in standby mode with battery under 25° C.
LG told me to ask for a replacement
Some of us did it and had the same issue on the replaced phone.
I read it is due to hidden menu/car navigation/ecc. ecc.
There are no prooves about it.
Could it be a ROOT problem?
No. Same thing happens on both rooted and original phones.
I got it. It's a SD problem
Some of us has this problem both with or without SD card
So it's a HW problem
We are not sure about it. Most of us (me too) think this is a SW related issue. Some other thinks about a HW one.
Anyway it looks like a Nvidia/Tegra related problem.
It happens on Motorola Atrix too:

So: what can I do?
Follow this thread and partecipate
Try to install latest version v10b and do a full reset.
Try to uninstall the "Any cut" application.
Try removing your SD.
NOTE: These are temporary solutions while we wait to understand something more.
Nothing else?
Sure, you can add informations here to keep updated the FAQs.
What about contacting LG?
It looks like something is moving and a new update will be released soon:

Mine has now shut down 3 times while i was in a call, battery pull on each occasion to rectify the problem

Added in the first question that pulling off the battery temporary solves.

1 week ago I do faced 2 time reboot each after receive sms during standby mood.
Dont know what happen.
Later I remember the reboot problem started after I had installed "Any cut" sw and started to activate the hidden menu.
Then I uninstall it and now haven facing any reboot no more.
Already 1 week pass and no reboot at all. I also never restart my O2X yet and seem everything is OK, no lag or etc on the system.
Hope this help.

Was using the original lg rom only for a good day and had one shutdown. Switched to custom rom and didnt have a reboot or shutdown yet in over a week. Appears to be software related.

Useful topic, thanks!
My experience in 15 days of use.
with stock rom V10a and external sd:
- 1 time screen locked black in a warm day during standby
with stock rom V10a without external sd:
- many times screen locked black just after a notification (almost always after sms incoming notification)
with official rom V10b without hard reset and without external sd:
- 1 time reboot after pressing power button to exit from standby
- 2 times screen locked black the day after I've changed the useragent setting from the hiddenmenu and installed "AutomateIt" app
with official rom V10b after a hard reset 2 days ago and without external sd:
- no problem till now (2 days of use)
All the time I used both original charger (at home) and a generic usb adapter with an output current of 1mA (at office).

This is the sort of stuff that should be sent to LG to deal with. Not the idiots at call centres but the people who made the phone and get them to work on it.
Problem with these phone guys, they make a phone and then just stick out to the salesman and then when things like this happen to everyone we get no support or real contact.
It's always send it for repair. The phones are like a month old and that is really a valid response?
Time LG were held accountable (as well as other company's)

Ok, added some "Possible solutions"

Good thread, will hopefully cut down on some of the idle speculation that has been going on!
I believe that it is a software bug, namely in Nvidia's cpufreq-dvfsd driver. I saw this process misbehaving when doing a 'top' command via an ADB shell after it froze, and I'm not the only person to have witnessed that. I've posted that info over at MoDaCo.
As kholk is the only person other than Paul I know around here who might be familiar with a Linux kernel, I've asked him to take a look. Not sure what will come of that, if anything.

And just to add fuel to my argument that this is a Tegra/Nvidia issue, and *not* necessarily an LG one, check this out (from Moto Atrix forums):
http://forum.xda-developers.com/showthread.php?t=969974
http://forum.xda-developers.com/showthread.php?t=1009510

Read from the postings that, for charger-specific reboot/lockup problem, it might be better charging from a computer USB port or a charger with lower current output (I think someone is using as low as 350mA).

Fyi, I've never had AnyCut installed and I've had these problems.

Yup, we do not have still found THE cause, but some events.
We are trying to understand if they are related to the issue.
I am reporting infos from the other thread and from this one to help people ti find a partial solution.

Very interesting withoutwings
A problem related to tegra system could explain why LG can't solve anything?
Checking all of the messages I can see that the problem is one ( phone locking/restart) but the symptoms are very different and almost always unrepeatable.
Is also strange that many people have a lot of apparently casual restart/lock and many other people have no problems. If a part of source code is corrupted I think the problem should occurs for all the phone.

Not necessarily. In embedded/real-time systems, timing is crucial and in some components varies according to manufacture tolerances, heat, etc. Also everybody's phone has different apps and they do things at different times so you can't say that everybody's phone is just "the same" as everyone else's.
And this bug could well be one that only happens for some very specific condition that the original developer didn't forsee when he wrote that code or tested it. But the law of chance means that so many of us are seeing it - some more than others, and some days worse than other days.
So this would explain why people think that doing something like switching launcher or taking out an SD card might be solving or making the problem worse, because every action can and does change the likelihood of this specific condition occurring by changing how the phone behaves overall, workload, sleep time, etc etc. And why all these "solutions" that people are posting are so random and unrelated but each person is convinced that theirs is the one that works!
Basically, we need more evidence from logs to see what is really going on...

how to fix turning off issue for samsung i9000 ?

I just have updated my mobile from 2.2.1 to 2.3.4, i used this forum tutorial - http://forum.xda-developers.com/showthread.php?t=1139050
I have issue - my phone is turning off for no reason, you know i don't have lots of apps only fb,twitter,skype and 'advanced task killer'
actually when I am doing Skype video calls, writing SMS or anything else my phone just changed to 'black screen' every couple hours and afterwards my Samsung turning off with sound. To turn on I need take battery off and then into back then he allow to turn on...
before I updated I had little bit similar situation, my phone had 2.2.1 version and i didn't have black screen, but my phone just had 'freezing' for 10 sec or more...
what's problem for? what's your suggestions ? thank you a lot.
Ed

I have this issue as well, although it doesn't happen as much since I upgraded to gingerbread. I did have it happen once the other day. I was listening to music and I needed to make a call and when exiting the music app, it froze. It then went black and I had to take battery out and put it back in. It's annoying if you got a otterbox case on it with two layers. I had heard updating to gingerbread stops this but so far I don't think it's 100%. I use my phone as my alarm and one time it went dead with a full charge and I was almost late for work.
Let me know if you figure something out.

what can say experts about our issue ?
I will take some day my mobile to repair centre.. it's sad if couple of people have same issue and nobody can tell us the problem reason.

Try to flash a custom kernel and see if it the problem is still there

can you tell me or give information what's is 'flash custom kernel' ?

I have also encountered this problem, very frequently if i may add.
the problem actually first occured a few months ago, after i updated my firmware to gingerbread.
In my case the phone does not freeze, the screen wont turn on or respond to any gestures (hardware/capacitive button won't too), however any running process still runs, in specific i can still recieve phone calls, or at least hear the ringer.
I know of many other people that encountered this problem, all came from different ROMs (MIUI, SH 3.5 and up, Stock, PilotX etc..) and i, for one, can say that in the past two-three weeks it atarted appearing a few times a day.
So - does anyone have any ideas for the nature of this BUG??
BTW I use the i9000t which i own for over 7 months now.

Same problem
Hi, I have the same problem here.
and have seen this myself on stock roms too.
It doesn't happen very often (only once on my phone for now) but it is getting me pissed off as no one knows the nature of this BUG.
could it be a problem with the latest 2.3.4 version ? or an update of one of the applications?
I don't have too many apps on my phone only skype and 2-3 games.
the only thing I can think of right now is that all people who had this bug had skype on the phone but I don't really think it's from that.

Hi, And-roid if u ll update to 2.3.4 your mobile will working deffo better, i suggest you update your mobile to 2.3.4

Hey eddys, i have 2.3.4 for over two months now, and the problem just go worst...

Hi eddys,
I have the 2.3.4 (and my brother and sister in law have it too with a stock rom).
this is happening on all roms and all kernels...maybe a problem with the 2.3.4?
I don't know but it is very weird, no one has an answer for this....
edit:
just checked this with my phone supplier and of course they have no idea what so ever about this bug.
come to think of it they didn't even know how to fix my brother in laws "problem" when the 3G internet didn't work (settings-->wireless and network-->mobile network--> check the V on Use packet data ) so no surprise there.

Anyone???
Maybe theres another forum that this problem should be posted at??

I have this bug too, but only while tethering. I've found a solution to the tethering related crashes - after you start tethering, go to the SuperUser settings, and disable root permissions for android wifi tether. Your phone shouldn't crash anymore.

hey zyczu,
unfortunately, I do not use tethering at all, do you suggest i should disable ALL root permissions?
This bug is really getting on my nerves!!!
Everything else, but this, is working great...

Since upgrading my i9000m to 2.3.3 through Kies, my phone has exhibited similar symptoms 3 times: freezing, not responding to touch etc.
The first time I had pulled the battery when it did this, but the 2nd time I had just put the phone down a minute or 2 earlier so display was off so didn't notice it(about 2 weeks ago). And the 3rd time(today), I was using it at the time, and so started taking off my rubberized case, only to have it restart before I got the chance to pull the phone back off.
Startup took much much longer than normal, which I recall the startup was similar during the 2nd "freeze & reboot". For some reason today, I randomly though maybe its an OTA update so I checked "Settings..About Phone" and found my kernel version listed as:
Code:
2.6.35.7-I9000UGKG3
[email protected]#2
I have no idea what it was before, but September 8th was 2 days ago... It is possible it said that before today's restart but no idea. I have a PIN on my SIM so when starting up have to enter PIN for it to work, but on these auto restarts I never got asked for my PIN so it could have restarted other times too without me noticing(ie. middle of night).

Hmm, mine used to something similar when I would leave Bluetooth on but would move out of range of a paired device. After a few minutes it would just shut down or stop responding. Haven't had that issue since moving to Milkys rom.

hi guys, i just used this tutorial http://androidadvices.com/how-to-up...0-to-stable-gingerbread-xwjvh-2-3-3-firmware/
first I installed 2.3.3 XWJVB then 2.3.3 XWJVH
just doing step by step...
my phone was working fine 2days then i had same issue and then I changed to original SAMSUNG battery and it's working perfect.
try this..
p.s. what kind of batteries you have 'original' or 'non-original' ? thank you

madmigs:
I did not notice the kernel version ive had before, however i took my phone to a service center today, and for what i can see i have the same version as you do, take aside the i9000t instead of i9000m...
eddys:
Ive been using different batteries orig/non-orig on and off, although since ive noticed it hurts performance i stopped doing that, do you suggest that this might be the cause of the problem?
If so, the factory wipe i just did (formatted the internal SD card) should do the trick.

try reading this it helped me since i turn the wi fi off when i go out
http://androidforums.com/samsung-galaxy-ace/312084-randomly-turning-off.html

Are you guys experiencing turn-off issue while phone is in the locked state. I mean you locked the screen and then after a while when you picked it up for unlocking it was powered off. If anyone has this issue, then I found a solution. Just let me know

my turning off issue went back and it's getting every time more annoying, I don't know what to do...

[Q] automatic random reboot

hey all,
i got my galaxy note now 3 weeks ands it's rebooting random all the time. at a service point i let them do a factory reset but that did not work. does anybody know a solution for this problem? because i dont like to send my note cause i will not have a few days sow if anyone got a solution i like to try it.

Suffering from the same here
I think its related to one of the apps - I will start removing my installed apps one by one from tonight - Will keep you posted with the updates.
Also, if anyone out there had the same issue; please advice!

I had the same issue on previous android devices..I managed to get around it with numerous hard resets. Also I believe that a certain combination of apps will cause it too..but i don't know which ones. I've got a dell streak right now, and its been stable for a few months..having said that, it still randomly reboots once in a while but no where near the consistency it used to.

I had this problem too and it seems to be an installed app problem, particularly any that change the wireless settings in some way or apps that stall when accessing the external SD card at boot times.

this is exactly what happens to me guys, same problem.
Random reboot and this happens all around the clock, no matter if it is day or night or if the phone is in flight mode...
Frankly I don't want to uninstall my apps one by one to check what app is causing the issue because I have no time to spend on it...
I hope that someone with more software skills than me (I am just an user) will succeed to fix it...
cheers.

Do you have Dolphin browser installed?
If it's the case, don't search further...

What's the problem with dolphin browser? I constantly use it and never had a restart. Is OPs phone overclocked or undervolted?
Which rom and kernel are being used?

mine is also rebooting every once in a while for no apparant reason. Mostly when I unplug it from the USB cable but not always. This happened from the first day on. I never did a factory reset but considering it now since the SMemo app is not working anymore (no strokes are visible) and I am out of options.

Dolphin is a well known app for causing random reboot, since SGS 2.
Not for all users but for many:
http://forum.xda-developers.com/showthread.php?t=1321612&highlight=randomly
But without Dolphin installed, I really don't know...

I think it's the SD card causing these problems.
My reboot problems all disappeared when I removed the 32Gb sandisk card. I replaced it with a 16Gb card and was very careful about which apps I installed on it. Now whether it was the card size/brand or the selective apps that resolved the issue I can't be sure. Having Dolphin's cache on the phone memory instead of the SD card might also be a solution.
But it's worth investigating if you have reboot problems with external card installed.

Hi guys,
As soon as I got my Note, I rooted it and flashed a custom rom. Never had problems with reboots so far.
So, for a change I though setting it beck to stock was a good idea, with the upcomming ICS update.
As soon as I flashed the stock rom with odin, and it was back to factory situation, the reboots start happening. Every 3-6 hours the Note rebooted. Got in contact with Samsung (NL) and suggested to execute a factory reset, so I tried that a couple of times. But no luck, the reboots keep happening. I thought maybe it was an hardware issue. I have no Sdcard, only my SIMcard, which was a bit warn out, so I order a new SIM. But still, the reboots keep happening.
Then I decided to root my device again and flash a custom rom (Rocket-Rom), and guess what? No more reboots!!!
I hope this helped.

To me, I think automatic reboot is somehow still acceptable. I experienced two times auto power off. Both were happened after I charged it over night, unpluged the charger and left it without unlocking the screen, drove to my work place, and found it dead
I'm only having it for 2 weeks and I haven't rooted it.

it maybe a usb charging issue which is causing so much grief to many note owners. Mine has a defective usb port and it makes my note go crazy, including reboots and makes the note think its charging when its not even connected to charger at all.

Using note since dec... Faced such problem 5 or 7 time whn my phn was nt rooted... But nw its working fine... Using rocket rom v 20...

[I9001] MicroUSB Hardware Problems

Hey guys,
I hope you can help me with my problem. I have it now about 1 month and I think I'll have to send my SGS to Samsung if you don't have any idea how to solve this problem.
About 1 month ago (a little bit after I installed arco's cm9, first released version) the phone always showed that it had an USB connection, it always said it was being charged and I couldn't change the USB-Connection-Type to Kies or Media Player. Because of this, I made a backup through CWM and reinstalled CM9 - but the problem was still there. Even after a full wipe of all partitions (system, data, caches) the problem was still there. So I restored a backup I made 3 month ago, where the problem definitely wasn't there. The restored ROM was CyMod. But still, the phone thought it was continual plugged in. Then I tested updating to a stock firmware with Kies - but the software failed doing it.
I thought I would just wait a little bit, because the problem may fix itself - and it partially did. Now, sometimes everything is normal, but the biggest part of the time it changes every second if the Phone is "plugged in" or not. And the bad thing about this is that it keeps the display running all the time. Sometimes, if I knock with the part where the USB-hardware is on my table, the problem is fixed, till I plug it in again or lay it down (even if I lay it down carefully).
So, is there any solution for this problem? I searched XDA Developers and almost the whole internet, but I didn't find anybody with the same problem.
It would be really cool if you could help me. If nobody of you has a solution, I simply send it so Samsung.
Thanks in advance, GC98
PS: Sorry for my bad english, but I learned english for 5 years now and never wrote a post like this before ^^
