GPS problems - Galaxy S II Q&A, Help & Troubleshooting

Hi was wondering if anyone has similar problems to me with the GPS not getting a fix. Most of the time it functions fine with Google navigation but there are times like tonight when it cannot get a fix. I downloaded the GPS status app from the market which showed only a couple of satellites where visable and it would lock on to any of them. I then went in to the tools part of the app and reset something called a-gps data (whatever that is?) Then I clicked the download link and it received some data. After that the GPS got an instant lock and has been fine since.
I just wondered if anyone else experiences these problems and if so how do you fix it. My nexus s never had a problem getting a fix I'm just curious as to why I'm having problems with this handset
Edit to say I updated to the latest maps yesterday so I wonder if that has anything to do with it?

I have been experiencing some delay in google maps, but i think that is because i am traveling right now, and i don't have Internet access every where. But you should have clear view to the sky has well

this thread.
helped a lot of us out. agps is assisted gps iirc. instead of doing calculations itself, your phone downloads data instead (i think).

Thanks ill have a look at that thread. Seems to be working well for the time being but for how long I'm not sure

makes a world of difference. get a lock within 5 secs normally as opposed to upto 5 minutes!
just remember, if you flash a new rom, the conf file gets replaced. i was convinced that the rom i was on was causing poor gps until i replaced it with a backup off my sd card

So does this require root tommo? I haven't had chance to go through the whole thread yet as I'm not at my computer. I'm not rooted so would have to go through that procedure too

yeah, you need an app like root explorer to get access to the "etc" folder where the gps.conf file is.
very easy to do mind.

Thanks buddy ill give it a try once I get home

[Q] What is going on with my Android Market?

Randomly my Android Market started acting up with regards to downloading apps. I can browse through and search apps just fine but when I click Install to start downloading an app it just hangs on 'Starting download...' on and off wifi.
I researched the problem and found remedies of starting gtalk and clearing the download manager cache, all of which were ineffective (obviously otherwise I wouldn't be posting this!). The only thing that was temporarily effective was re-flashing the stock firmware with odin. Initially I could download apps after flashing with odin but after letting the phone sit for a few minutes I could no longer download apps :-(.
On a perhaps related note I do recieve random notifications about unsuccessful downloads while I'm not even using my phone of applications that I've never even attempted to download..
Yeah I get the same issues with mine on the stock rom.i find that if I reset my wifi connection it starts to work again. Just a thought.

Ineffective for me :-(.
Anybody ?
Playing around with it a lil more if I toggle the wifi then restart the download it generally starts workimg again. Just out of curiosity are you in a poor reception area when this happens?

Had this issue on my G1 with CM6. Go to Settings>Applications>Manage Applications. Scroll to market, click, clear cache. Let me know if this works as well.

Tried this as well as clearing the cache for download manager, no difference.

Nope, I either have great EDGE or HSDPA service.
Before anyone asks, all other web based apps that I can use at this point (browser mostly) work just fine.
My best guess is that it is just buggy atm, it would seem that it has a hard time deciding which method to use to download. For me at least choosing between wifi and edge/3g.

You can uninstall the market from your manage apps/applications without any harm. Won't remove the app, but will clear all the market data stored on your phone. You just accept the tos again when you open the market and you're going. Hope this helps

This doesn't belong in the development section, and you should use the search function.
Not sure what they did for the Vibrant, but you can try what's in post 81

Thanks, NOsquid
I tried the listed instructions with little success. Then I tried the "warm start" selection and get very quick locks with more satellites in use than ever before. Ill try navigation and see what happens with continuous use.
Yeah, just keep testing for yourself. The problem allegedly is one of improper caching so the warm start may end up screwing you - see satellites but not lock. The cold start may take a little longer, and you need 3g.
Allegedly
I don't know if this is relevant, but there is an app called gps booster that really works in less than ten seconds to acquire a lock on gps. You may want to check it out...
It's legit because algorithms are used to estimate gps satellite locations.

[Q] Is the market having issues?

No matter what rom (with wipe of data, cache, and Dalvik), known-good Nandroid backup I restore, or anything else I can think of, I cannot get the Market to work. This is driving me bonkers! I've tried CM7, das Bamf 1.6 and 1.6.1, I've tried old Virus backups, and have even flashed Bolted, Lightning rom, and a couple others. I simply cannot get apps to download, and all environments give me 503s in my logs. So this sounds like it's down but I searched and expected to see posts all over about it. So I'm stumped.

Had the same issue, no replys tho. I ended up calling Verizon and after the tech guy "held my hand" thru his "testing", he just put me in for a replacement. I did notice that market seems to be working a bit now. It wasn't working after I uprooted bone stock, but today it seems to be kinda working.

So after sleeping, it's still broken for me. I did additional testing and either the market is very broken or my market account is screwed up. I tried on my 2 other devices (a Nook Color and a G1, both on wifi) and neither of them with either.
I did some heavy flashing of various roms yesterday, so could they have disabled my account, or something, thinking it was hacked?
Sent from my ADR6400L using XDA App
Okay, so no matter what I do, I can't initiate a download from my phone. I can, however, initiate a download from the web version of the Market, and this works with at least my TBolt and Nook (didn't bother trying on my G1 - assumed it either worked or I didn't care).
However, this is incredibly aggravating not being able to use my phone to install software via the Market applications!
I've discovered the problem (kinda) and can offer a fix. The problem was that network settings (grouped with things like wifi passwords) get backed up and restored automatically by Google, and mine were somehow corrupted. The fix was to go into Settings -> Privacy and uncheck the backup/restore checkboxes. If you do this right, it will prompt you to confirm and will say that it will erase the settings on Google's servers.
After this, you may need to wipe one more time.

[Q] BroadcomMEMsService crashing

Hi,
After I have upgraded my Galaxy S3 firmware to the latest official firmware upgrade from Samsung and root it, intermittenly I have the pop box saying that BroadcomMEMsService has stopped.
This has happened quite frequently and it become quite annoying because before the message comes out the phone will freeze for a short time.
Anybody has same experience and how to solve it?
Cheers
Factory reset, wipe cache and advanced/dalvik on CWM recovery
Sent from my GT-I9300 using xda premium
I have the same problem on a rooted S3.
But I do not see any reasson why this should happen on a stock rom with root permissions. So I do not factory reset it but wiped the caches - no effect.
The problem only appears if mobile data connection is deactivated. I think it should be a problem with some service that needs agps service e.g.
Letting mobile data connection enabled is a solution for the next weeks but not a good option.
I have noted the almost same thing but it happens when the data connection change from G - 3G - H - H+... Btw my data connection is always on... still looking for solution..

I would try it but sadly I have not enough time for playing arround with resets and restores without being sure that it helps. Thats why I prefer to know the reason first before I begin...
And there are a view people on the net who commented that only disabling specific apps which are in need of agps (e.g.weather widget) had lead to success...

Yes - think you are right. But I have a lot of stuff which I changed in /system /data etc. and a lot of scripts that I have to sort and backup before. That takes a view hours/days after work so I think I will try it next week.
Found a temporary solution to avoid the crashing is by turning on the GPS... at least until a new rom comes out...

Hmm I see 2 possible couses in my SGS III:
1) Full Keyboard - the error first appeared when I started this app
2) It might be hosts file since I installed Debian kit and using Debian on this phone..
I will try create hosts file and let you know..
UPDATE: /etc/hosts is existing so this is not the couse. I will delete Full Keyboard and let you know.
I did what you say but the problem still occur....
i try to hard reset everything still can't find solution
Afaik the satellite navigation (which on the S3 is GPS + Glonass) is controlled by the modem.
You might want try to flash another modem, maybe it fixes the issue.
Which ROM and version are you on?
Any chance of a LogCat at the time of it crashing?
CF-Root-SGS3-v6.4

Can u gv me the link to flash another modem?
Thx for ur help
no problems on mine but try reflashing the rom
I am having the same issue... i get this ramdomly no matter whats on , gps, wifi, 3g or even when all of them on at same time

"Super Clean Wipe" or something like that

Hi people.....w/o long disortation...
Isnt somewhere out there a super clean wipe... (not odin) that some devs suggest that we use b4 flashing. ..just to get a clean slate....
I believe I need that...bc I am using a rom ported from an international rom...and gps is speculative. I basically dont have gps lock (it locks and then somehow it looses its lock..and through some marvelous people helping we think I am not getting a complete wipe...via twrp... (tried everything)...so thats why I am asking for this "super clean wipe" or something like that. ..
I know there was one for the Verizon Gnex

Use FasterGPS to change the gps.conf back to the US. It is fairly straightforward to use, just give it root privileges then:
1. Under continent select North America
2. Once you select continent the Region box will become selectable, you need to choose United States.
It will show a toast message that says the GPS.conf was written successfully, then you just need to load Maps up and it should lock on quickly without losing the signal.
If that doesn't work just post back and I will give you something else to try because AFAIK the Super, Mega, and whatever the hell wipes aren't recommended for this phone and if I am remembering correctly they caused soft bricking on our phones that was a ***** to fix. While this wipes have most likely been fixed I wouldn't bother with them, if you want to do a wipe because what I told you to do doesn't work then you just need to boot into TWRP, click wipe, click the box on the right side (I think its format data or something but I can't remember off the top of my head), type yes, click go and then reflash whatever you want. At least try FasterGPS first, that works most of the time on International Roms.

With this fix you don't have to push anything at all, just boot into recovery and flash it like you would a ROM. Don't bother wiping anything with this fix, just flash it.
http://db.tt/9E3aMJxS
Also pushing files isn't that bad when you use something like Root Explorer, all you have to do is copy and paste it to wherever it needs to be. If you have to fix the permissions after pushing it you just have to long press and change them, it will load a little box with all the permissions and all you have to do is check the ones needed.

What the hell? There was a report of that in the thread in General but I figured it was bogus because the person would never ever reply and every single ROM I have tried it on, TW included, it either fixed or did nothing.
When you restore your nandroid does your GPS go back to the normal non working state?
Something else you could try, that i just thought of when replying to someone in the VRB thread, is making a nandroid of a TW ROM, that you got a strong GPS lock for at least 5 minutes, on your internal SD and then try either reflashing Moon or restoring a nandroid of it. I would probably just reflash it to have a clean slate but I would also understand if you didn't want to have to go through setting it up again.
That probably won't work but I know on my S3 I had to have a working backup on my internal or else GPS refused to work at all, on my Note 2 I have to reflash the fix I linked above if I forget and wipe my nandroid before establishing a lock.
Also are you trying to get a GPS lock with or without the Wireless network setting on? I know on AOSP having the WiFi and Mobile network location setting checked in addition to the regular GPS location it would refuse to even turn the GPS on. You had to have the wireless location setting off before you could get your GPS to work, while this isn't AOSP it could be a shared bug and is worth testing out.

For my Thunderbolt there was a file called "SuperWipe" that was essentially a blank file system that you could flash to your phone to quickly clear EVERYTHING.
I have not seen anything like that for the Note II yet.

It was released right after the phone came out. I want to say it was released in the N7105 forums, it could have been AT&T though, and there were some serious issues it was causing in all the Note 2's. It was supposed to have been worked on but I haven't heard anything since then and honestly wouldn't use it after all the corruption issues that arose from it.

That is the way i have always done it, on CleanROM ACE 4.9, Vanilla Rootbox, and all the other miscellaneous TW and AOSP ROMs I've used it on. It is made for AOSP but didn't hurt any of the TW ROMs I've rested it on.
If it completely got rid of your GPS when you tested it before though it may just not be a good idea to use it on Moon.
When you're testing GPS do you always have the WiFi and Mobile Network Location seeing under Location Settings checked? I know on AOSP for a while you couldn't use that setting at all and then on some TW ROMs you had to use it to get your first lock and after that you could get away with not having it enabled.
I would just flash Moon ROM and see if you can get a lock. Try it after creating a nandroid of a TW ROM that has working GPS on your internal storage, on my S3 the only way I could get a lock on any ROM was to keep a nandroid with working GPS on my internal SD card.
