[Q] I9100 GPS hardware issue? - Galaxy S II Q&A, Help & Troubleshooting

Hello! I have recently noticed that GPS on my I9100 does not seem to be working. I think it used to work before but I never used it to navigate, just for the maps and those will give me 20m accuracy with WiFi only.
Tried various fixed found on this and other forums, fasterfix, modyfing gps.conf manually, the a-gps fix but no results. I have downloaded GPS Status & Toolbox app and it looks that my phone does not find any satellites at all. Other Galaxy S2, my friend's phone, easily gets around 8 satellites in about 5 seconds outside and mine finds nothing, even after 30 minutes. Additionally, I tried flashing the phone with two versions of stock jelly bean and two different nightlies of cyanogenmod, still nothing.
Hence, I guess that the problem is in the hardware, not soft. Any ideas what else can be done apart from sending it off for repairs? No warranty and I suppose it would be just cheaper to buy a blutetooth gps receiver than to get it serviced.
Thanks, Tom

Since I flashed a custom ROM, I've had problems with GPS. Before you send it off, try this, it works for me http://forum.xda-developers.com/showpost.php?p=41582224&postcount=8307
I use this fix on all the ROMs (CM/AOKP base) I flash now, as it never works until I modify this file. After I modify it using this, no issues. Give it a shot, make sure you backup the original file though. Note that you need to extract the attached file before replacing it.
Edit: or try omega AOKP, which says it has 'instantaneous GPS fixation' in the OP: http://forum.xda-developers.com/showthread.php?t=1290468

GPS suddenly stopped working

a month ago i bought a brand new Sprint TP. And i was amazed by its GPS, it's the fastest mobile phone GPS i ever met. it only need 5 second to lock satellite. but yesterday suddenly it stopped working. with identical rom and identical radio. it's so weird. i try it to flash back to factory default and yet it still didn't worked. try also to update the radio but no hope. Do anyone have a solution for these weird problem?
are you using the stock rom & radio? you say you tried flashing radios but to no avail, which part failed? you were able to flash a new radio but it didn't solve the problem or you weren't able to flash a new radio period? we need a lot more information to help you

If you have already reflashed the rom, it could be that you have a damaged unit in your hands. If I were you, I would relock it and run to a Sprint store asking for a replacement. Just my two cents...
Good luck!
[SOLVED] here are the solution:
hello friends, recently after i upgrade my Sprint TP ROM into several different type of ROM, my TP GPS can't lock and view the satellite anymore. i got frustrated and hopeless about it. i already tried almost every single method until i find these one:
http://www.smartphonejunkie.com/gps-still-cant-t183417.html?t=183417
so i matched the IP between QPST and the IP server and port number on HKLM/Software/HTC/SUPL AGPS. After i match both of it, suddenly it start working again and the result is superior. i can lock 8 satellite even indoor on my private room. when i got outdoor it only need around 3-5 seconds to lock. so it even faster than before that need around 20-30 second with QuickGPS. sorry for my bad english, i just want to share a GPS problem that actually very tricky and have various problem.
Note: i never changed any settings on my QPST and i set the SUPLAGPS to follow my QPST value.
it's interesting that each time i changed the ROM, it also changed the IP and Port inside that registry.
hope this tricks helps. thank you
I just had that happened too...
If the above suggestioon does not work, I had applied this fix which worked for me when my GPS suddenly stopped working for no reason. My stoped working just a day before yours did. This of course happed just as I REALLY needed my GPS to work.
Here is the Fix.
Using a registry editor .....
HKLM/Comm/ConnMgr/Providers/{7C4B7A38-5FF7-4bc1-80F6-5DA7870BB1AA}/Connections/Phone as Modem
Change the value AlwaysOn=1 to AlwaysOn=0
Soft Reset..
Worked for me.
If I helped send a thanks.

Keep losing WiFi connection!

I got my phone back on Wednesday from the repair people that my insurers use after dropping it last month and shattering the screen inside (fortunately the phone itself still worked properly)
At the time the phone had been dropped, I was having problems with it in that the phone couldn't get a phone signal at all and I was going to fix the problem myself. The repair people knew that it had been jailbroken and I explained that I would fix the problem with the lack of signal myself.
Now, I have a new problem in that every time I get a WiFi signal, it keeps getting disconnected within seconds and I've noticed that the repair people seem to have reactivated the infamous "Flight Mode" problem which seems to have somehow affected the inbuilt WiFi system in that every time the phone manages to detect a signal, whether it's at home or elsewhere, such as university, it loses the signal.
In any case, does anyone have any suggestions on how to fix the problem (I installed the latest VillainROM yesterday which is 3.0) including what modem to use and how to install it?
I would try some different modems and see if you find one that solves your problem. In the first few posts of the VillainRom thread is a link to the thread attachments. Included in there should be a few modems in zip format which you can flash through CWM. Also some of the posters (I think one is geko95gek??) have them in their signatures.
Hope this helps

Hey there, not sure whether this is an ongoing issue, but the problem seems to be related to the embedded kernel from VR 3.0 (Nimphetamine 2.0.5) I was facing exactly the same problem. The only way to fix it was to flash a different kernel (siyah 2.2 in my case) .
I tried all available radios but nothing fixed it, maybe pulser has to take care of it in the next release, so flash another kernel and the problem will be solved, good luck!
Yep, as in above post. WiFi drivers are found in the kernel. Try Siyah, Speedmod etc.

[HELP]-Rooted Atrix, Radio/WiFi/BlueTooth Error/Problems

Of course I searched around the forums for a fix but I could find a direct post with a fix. I rooted my phone a year ago ish and installed different roms. Recently added the beta CM 10/10.1. Everything worked find for about a month. Then for some reason the wifi stopped working. Got an error and then the phone crashes/reboots sometimes locks up. Tried recovery into other roms and still nothing. I read its a possible hardware fail but that cant be the reason. Every once in a great while the Wifi will work for about a minute then error out.
Does anyone have a fix that worked for them that had same symptoms? Or know of a working fix?
Thanks.
Applying pressure to various points with various objects seems to have helped some. Other than that, it definitely sounds like the well-known hardware failure. Just because wifi works now and then doesn't mean it's not it.

no gps lock, auto rotate and presence sensor doesn't work

first I've tried about 4-5 roms from stock tw to aosp style.
I get a gps lock but it's waaaaay off, floats around and doesn't give me my true location, maps, ingress etc none of them work properly.
my auto rotate doesn't work on any rom, beans/alliance dn3 gummy etc, it doesn't matter. if an app is landscape it tends to work and i can force an app to rotate aside from my camera app however nothing that should rotate when I turn my phone on its side seems to work. I. basically deal with it however is starting to get frustrating, I've tried everything I can think of and can't get it to work.
any ideas on what might fix this or is a warranty replacement the best course of action.
and lastly my presence sensor won't work, in calls the screen doesn't turn off I have to manually turn it off, I don't understand. it used to work great I could just place my hand in front of it on calls and it worked, not anymore.
I'm thinking I should just get a warranty replacement my quandary is that I've got my bootloader unlocked and I'd like to get another note 2 with an unlocked bootloader, however I know that's more always possible.

Chances for getting another Note 2 with it still on 4.1.2 is slim, but there is a chance.
Thats is weird that all of sudden this problem started occurring.. You did not drop your phone or do something that may have effected these things?
Have you tried to Odin a Stock Recovery and perform a Factory Reset? You might want to give that a go and see if it solves these issues.. Also when testing GPS, I have always resorted to an app called GPS Toolbox. It works great!

I have dropped it a few times however it lives in a TPU case, I've never dropped it from higher than about waist high. though it is possible
I'll try to Odin this weekend, can you point me to the most up to date rootable odin, I've done some searching I'm just not sure which is best.

Use the Stock Recovery image in the stickied Data Corruption thread in the General Section..
well I've tried a couple of different methods, guess something really is broken... I'm going to go back to bone stock and call VZW to get a replacement, damn this sucks... I'm not going to be able to flash the stuff I want.
whatever as long as everything else works.
flashed back to VRAMC3 called VZW went through 90 minutes of troubleshooting and updated all the way to Kit-Kat... still doesn't work.
and to top it all off, my vibrate just started going really strange.
I'll have a new phone tomorrow, hopefully ghetto root works.
May Not Be THE Solution, But Finally Worked For Me!
So, I've been experiencing GPS issues on R3Ds Port S5, SlimKat, Paranoid, DN3, and Dirty Unicorns... been trying all the solutions being posted in the threads before factory resetting and starting all over.
BTW I use GPS Toolbox to test my GPS connections and get 0/0 satelllites.
In a last ditch effort, I loaded AllianceRom and GPS connected (20/20 Satellites with GPS Toolbox)!! I was starting to suspect that it was hardware until AllianceRom. As great of a Rom as it is, I will likely not stay on it unless I cannot get any of the other Roms to connect GPS.
I'll let this Rom run for about 4-5 hours and then with a GPS fix, try and re-install Dirty Unicorns or R3Ds and report back.
I'm hoping this can be a solution for a least a few, if not all (wouldn't that be nice) of you experiencing the same issues as I was.
got a CLNR last week and everything works great.
sadly, no roms fixed the issue and now I'm on locked bootloader ND7.
on the bright side ghetto root worked and wanam xposed is at least a decent way to get what I want, manually editing my the files to increase volume etc is a pain, however it's better than nothing.
glad to hear alliance fixed your gps, hopefully it stays fixed.

Random GPS loss

Hello,
I am running a rooted Xperia z2 international version with 5.1.1 and a locked bootloader (used the downgrade method and all the files I flashed were found in that thread). Virtually everything works fine, except that the GPS intermittently loses signal, which has been causing a lot of issues.
It started in maps, so I reinstalled maps. Still there. I also tried it in the Garmin navigation that was included, but it still lost signal. I then used fastergps to rewrite my GPS configuration file, but it still does it. At this point, I'm unsure how to fix this. I heard that I might have to reflash 5.1.1, but that would be a huge pain, so I thought to post here and see if anyone has any ideas.
Thank you.
Update: I have narrowed down the issue. It appears that when aGPS is not on, my phone can view the GPS satellites, but cannot lock on to them. I have read some rumblings that this is related to the firmware, so I am going to try and downgrade to 5.0.2 to fix these issues. I will keep this thread updated as things develop, so that this can exist in case anyone else has this issue.
2nd update: rather than downgrade, I tried loading the. 232 firmware (I had the. 546 firmware before), but it appears that does nothing. I'm in he very of uprooting and calling in the warranty. Before I do, does anyone have a suggestion on something that could fix this?
i've noticed that my phone randomly disconnects gps satellites too. After half an hour of using it with location on, the gps signal goes down, so i need to deactivate and reactivate the location to reconnect to satellites. pretty disturbing when tracking my routes. Hope Android 6 will not have this bug
So, as an update. Over a month goes by while I am sending my device back to the place I purchased it from. They supposedly fixed it and shipped it back, but when i got it today...still no GPS. I know I'm not the only one that has had these issues: (https://talk.sonymobile.com/t5/Xperia-Z2/Problems-with-GPS-on-Z2/td-p/702261, https://talk.sonymobile.com/t5/Xper...ter-lollipop-update-in-Z3-compact/td-p/967188), but those threads didn't lead to any answers that have worked. I have tried everything, so I am just seeing if anyone has had this issue, has had any success with fixing this GPS fix issue, or can do anything to help me. Thanks.
I rarely use gps but I've never experienced issues with it, however last time I had also some problems.
While traveling in Germany the phone lost it's gps signal every few minutes for couple of seconds. However after I've passed the border with poland the gps was working fine.
So maybe it really has to do sth with the carrier or even country ☺ (I had no agps turned on).
