Galaxy S4 i9505 GPS issue - Help - Galaxy S 4 Q&A, Help & Troubleshooting

Hello Experts,
It's been ard two months I am struggling to get my gps work on my s4 which was working when I bought the phone and was on stock Samsung OS.
It's started when I rooted my phone. Subsequently installed CM10.1 nightly (I guess 24/7/2013-nighly). Now I am on cm10.1 rc2.
Gps status show 0/0 sats. No satellites in view
Any suggestions or help would be appreciated.
Thanks.

As you are rooted, something worth trying would be FasterFix from PlayStore. You'll see what it does.
Good luck!

Thanks for response. Yes I am rooted.
Recently I installed latest modem (mh8) as well Which didn't help either.
I tried GPS status, GPSFix, gps test etc. Those didn't help. But never used to keep the gps open for more than 5 minutes.
Will keeping it on longer help?
Thanks.

Also if someone can tell me the permissions on gps.conf file if it matters.

My GPS error was caused by a software conflict - in my case, Yahoo Weather. It stopped the GPS from getting proper signal or lock, but when I uninstalled the app it returned to normal. The latest version of Yahoo Weather has fixed the issue.
Think about any apps you may have installed at the time of rooting. Rooting itself should not cause this issue.
You could try taking a full backup, reset the device and see if GPS works again with no user apps installed. If it does it sounds like a software conflict, if it does not then it is a firmware/hardware problem.

Yeah read that thread which talks about yahoo weather. I don't have it. Infact I did wipe few times to install new nightly. And checked gas just by installing Google maps, which didn't help.
Could it be a hardware issue? How can we confirm? My gps status show 0/0 sats in view.

Did you disable some autostart apps? I had the same behavior. In my case, I think it was a Google service.

If all else fails, unroot, flash the Original FW via Odin.

Noted. Will try and update, little tied up with some other things.

To see if is hardware you need clean install
1. Download odin 3.07 ( you have option NAND ERAS ALL )
2. Download MH8 ( If you are with knox ), / MF8 ( NON KNOX BOOT )
3. Download PIT
4. Odin - check NAND, PIT file, PDA AND START
5. After flash your phone wont boot ( stuck at samsung Logo )
6. Boot in recovery ( volume up )( original recovery )
7. Factory reset + format cache.
8. Will reboot automatically the phone
9. Install GPS TEST. And let it search for maxim 5 min. ( will be cold start )
Come back with result

Wow, thanks.
Few questions though
1. If I select NAND ERASE All, will erase everything what I see in internal memory?
2. What is knox boot?
Thanks again.

When you are entering in download mode and you have 2 lines there where is writen Knox kernel lock 0x0 and knox warranty void that means that you have secure bootloader ( you can flash only MH group or GG ). If you dont have I recommend to flash MF8 Or BGMA.
And yes NAND eras all ... is deleting all from internall memory

Hello there,
I did as you mentioned above. Unfortunately it didn't help. Is there something bad with my GPS hardware? I remember it was working when I was on stock ROM when I bought the phone.
I saw a post for GS3 which states tightening the screws to fix gps issue. Can we do something similar for GS4?

One more thing: install GPS test from Google market. And send me a print with the open app. BUT 1st enable GPS from settings. And bee sure to bee in open place ( outside) when you are opening the app

Removing demo ROM?

Hey guys.
I have got a demo unit of an s4 I9505 and it's a "live demo" unit that has a Samsung demo ROM on it that has disabled the SIM card slot. Do you know of anyway I can remove all the software and flash a ROM and have it working as a normal handset?
I tried installing a ROM via CWM after I rooted it but it said complete but didn't change anything. Also I'm CWM it doesn't have the option to flash from internal SD card, only external. Have Samsung removed some core files in this Rom maybe? I'm rooted but in superSU it also says "no binary found, this is a problem"
Any help would be great!
Thanks

Hi,
Look HERE
Is it an i9505 or an i9505x? If it has the "x", you won't be able to make phone calls even if you root it successfully.
Sent from my GT-I9505 using xda app-developers app
I saw that but got stuck at the "unpack roms" bit. I never use Odin I always use CWM so I just flash zips. Can you shed any light on how to get the file I need to select in pda?
Please be kind if it's a simple solution lol

Basically, it's a whole different unit than the i9505, and I also think I read somewhere it has different hardware too (it lacks a mobile network antenna IIRC but I'm not sure about that). Sorry, this is bad news for you I'm afraid...

Gps issues

Dear forum members,
I have used several Roms for my At&t galaxy s4 32gb and ranging from omega to the most recent shostock Rom with great success.
But my issue is as follows, my GPS will never lock on to any satellites since the latest shostock Rom was installed.
Ive tried full wipe, reflashing other roms that the GPS was working flawless on but with no luck.
I cant ever get a GPS lock where previously it worked great.
Any help would be greately apreciated since I really love this device and this isbthe first issue ive had with it since I bought it a few months ago.
Thank you

Check the settings for Location settings.
Also download GPS Test (free) from Google Play.
Sometimes Maps won't prompt to change setting for GPS and or WiFi.
Thanks for the response, I've done all of that but it just never locks on with any app, or tester. It just searches and searches, in the last week it started happening. Any other ideas?

I had the same issues and then I installed latest KT kernel and let Google maps use location reporting. Once I did that it locked with the quickness.

For messages not sending, I assume you're connected to your carrier's data network. If not, it's probably a radio issue.
Assuming everything is okay with your carrier, I'd try resetting your APN settings. Under Wireless & Networks click on "More..." followed by "Mobile networks" and "Access Point Names." Following this click on the three dots in the top right, reset to defaults... restart your phone and report back. :good:

Chances are there's a mismatch somewhere. I'd do a complete restore using the factory image from Google and go from there
I download the factory image from Google and it shows up under downloads but won't show up on ROM manager or in recovery its like it didn't download.. But ik it did

Can't enable Nfc

Hey.
Yesterday i flashed a new rom on my n9005, and after that i can't enable my nfc. I have also tried to turn it on with secure settings but i just says that there was an error.
So I tried to restore my rom, but nfc still not working. Also tried to recover with kies, and to flash stock rom but no luck. Also tried to copy the nfcnsi.apk from another Note 3, but didn't work.
So does someone know what else i can try ?

I initially had this problem after rooting but changing the CSC code to reflect the carrier ROM I installed fixed the issue.
Enter your CSC menu: *#272*[IMEI #]#
Hope this helps!

Wifi problem

Hi, is There any chance to install new modems without odin? I have a mac computer so I cant Flash via odin. I have tried heimdall and kies, none of them works because my Phone wont respond in the computer. Tried even With Googles file transfer.
The thing is that im a bit selective so I only found one rom that fits me, vision x II. Everything works perfect but i cant activate or use wifi. I really need my wifi cuz i have no signal at my Damn concrete apartment!

You can try do a FACTORY RESET:
- Make a Internal Memory backup
- From your home screen press the apps icon in the lower right corner.
- Find and press the settings icon.
- In the upper end of the screen press the accounts tab.
- In the bottom of the next screen press the Backup and reset button.
- Press the factory data reset.
- Read the info on your cell phone screen and hit Reset device.
I will test that

If you flash any modem , make.sure it is compatible with the firmware version otherwise you will hard break you device!!.
One more thing ,,the moment you flash it ...your device will reboot to download mode , then in this point you have to hold the power button for few second till it turn off . After that turn it on , the Samsung logo will show up ....and it may take time untill it move to the mobile odin mode ,,,, just wait for the process...dont ever turn it off again otherwise you may soft break your device
Also mobile odin only work in stock kernel otherwise it will not detect your device . Thats why it won't run in custom rom that only run in its custom kernel like cm or what ever rom ... this is the disadvantage
But the advantage is that.. it will never trigger the flash counter .
