GPS losing signal - ONE Q&A, Help & Troubleshooting

Hi all
I am running mahdi 0823 all else stock
Seem to be having issues with Google maps. Sometimes it locks on, but then loses GPS signal very often. Or it won't lock on at all.
I have tried other modems but it doesn't seem to help much.
Does anyone else have GPS related issues ?
And is there any known fix for it ?
Thanks in advance and have a great weekend

I was having GPS signal issues with the stock CM11s and Franco kernal. I switched to PA with Franco Kernal and now get good locks. Maybe it is a rom issue?

I am on cm11s rooted and GPS is fine here!

Try setting your network mode to 2G and see if it works that way

It works for me, don't know why, that's what I'm trying to find out.
Did it work for you?

same issue with gps! using franco and ak and mahdi rom.
maybe it is a mahdi rom issue???

I am having a GPS issue with stock CM11 44s. It works after a restart, but will stop working after a day. If I use a GPS status app, I see that it doesn't see any satellites in view at all. It's like the radio is completely dead, but then after a restart, everything is fine.

Same thing happening here. Losses satellite connection after a while. If I restart my phone it works fine.

Anyone found a fix yet? Mine also losses GPS fix after a while which is unfortunate because I use it as a sports tracker and it's useless if it doesn't work like it should.
I've tried CM11, CM11S, CM12, CM12.1, oxygen OS, some other ROMs any many custom kernels without any result.
It sees satellites, it connects, but can't get fix somehow.

GPS for exchange?

No matter if I'm on stock, cognition, perception, or any other custom ROM my GPS never works. "Your current location is temporarily unavailable."
Is there a fix for this at all? If not, could I still demand a new phone even after the 30 day return period?
It's build 1008
Thanks
Have you played around with lbs test mode? Tried jm9 or ji6 files? If you complained enough you may be able to get a warranty exchange
Where might I obtain the jm9/ji6 files?
Right now I'm running Serendipity 2.0, if it matters
Gps is still a no go on serendipity?
Have you changed your supl settings?

Yes...just returned mine today. Ask for 1010. Files won't fix it. It's the phones hardware.
My two 1008's were horrible...1010 perfect

I've tried switching from Auto config to the custom one, changing to control plane from SUPL, and deleting GPS data. Same result.
Gonna try flashing those GPS files, ty for the links.

Might have fixed the way the antenna is attached or used. Either way it's flawless now and both my 1008s were brutal.
Tried flashing both the GPS files, no luck. I'm going to go return it tomorrow I think.
From everything I have read build 1010 can not use, our has issues with odin one click. Personally I would except poor gps over no odin
hmmm...
What about build 1012? I assume that's the newest build, might be a newer one. I just want slightly working GPS at least
Do you have wireless location enabled?
If you just want to throw a ton of crap at the wall try this

I've tried wireless location, it worked, but only when on Wifi of course.
I would say do not use wireless location
After using last files I posted this is what I get in my house with no windows near me

Is there a way to fix GPS lock on Jelly Bean ?

Hi,
My GPS used to be locked within a second on stock ICS.
Now, I'm on Sky Jelly Bean, and I notice that it takes a long time to have GPS locked, and its accuracy is far from what we consider 'accurate'.
So is there a way to fix these GPS issues on Jelly Bean?
Thank you.

Install the AGPS patch in the dev section. It's never failed for me on any ROM I've used it on.

I just installed [Rom]Sky-JellyBean-4.1.2) Update 10.3 ((Base T10-(10/26/12)) GS3-Touchwiz--Vs--CM 10, and GPS wasnt locking either.

I downloaded the Google Specific 3.1 below, and GPS immediately locked:

Hope it works for you too.

Actually, I spoke too soon. It looks like the patch was working since it immediately locked on. I went out for a drive and used the NAV, and initially it was working, but after a few minutes it began to drop out and report "GPS Signal Lost"...
From your screenshot, it looks like you can see at least 12 satellites with fairly decent signal.
I am using a different app, and mine seem to vary between 0, 2, 5, and 7... Constantly changing. Wish mine looked like yours.
I've already wiped everything, and going back to stock using both Kies and Odin methods, but still have the same issue.
Read somewhere to wipe the external SD and eemc, so going to try that now.
Hopefully its not the phone.
What app is that screenshot from? Want to try it.
Thanks!
It's called "GPS Test". Pretty simple app.

Cm12 Mobile radio active issue?

In KitKat Display was the highest battery drainer. Now i switched to lollipop ,
Problem is that in c12 based Roms mobile radio active time is insanly high and drains my battary a lot.(See image)Does anyone else got this issues and is there any fix for this?
I usually do clean installs of my roms. When i am in wifi my battery life is mich better.
Here is chrome for example, but nearly every APP runnimg im the background has the same behavior.

seeing the exact same behavior on my device
Same for me.
which is installed gapps?
mobile radio active
someone managed to solve it?
Same problem here, it's on majority of my apps and the screen time is all the way at the bottom. I've switched Roms, modems and firmwares. I really don't want to go back to lollipop lol.
Any solution?
Same problem here. Clean install of CM12S. When I'm on WiFi I have no problem.
I think it's this is a know issue of lollipop. No one knows why. Someone have the problem someone not...
I can suggest you to go on privacy guard and block keep alive from the apps who use most of the battery... And sometimes check if they are running and close them...
Until someone find the fix... Like Wakelock...

Problem also here...IT's not a wakelock issue...Looking for a fix!
This is a screenshot the difference drain between WiFi and 3G
Issue ist still there in CM12.1 . Thibking about switching back to Kitkat.
Same problem, COS12 with default kernel. I changed the modem to see if the OxygenOS' one could fix this and one particular app (WhatsApp) went from 3+ hours/day to 40min/day with similiar use and signal reception, but others remained high
Even 5.1.1 has it
I can't believe this annoying bug hasn't already been fixed as I can't believe why the entire group of lollipop users all around the world is flooding the web underlining it.
I've tried at least 3 different 5.1.1. based ROM and they all have this bug (not to mention how many different 5.1 based ROM I've already tested or 5.0.2 as well for what matters).
Funny thing tho, the first day I'm using the ROM the bug never appears: it's only after a couple of days that the mobile radio active stats spike up to 2 or 3 hours for some apps that use internet (it could be spotify, google search, etc.)
Really hope someone comes up with a fix, this is getting more than annoying...

Which ROM fixes the most issues with 12.1?

I recently updated both my OPO's from 12s to stock 12.1-YOG4PAS3JL and there seems to be more bugs than fixes. Which ROM has addressed the following issues...
#1 In-call mic quality: This is the worst. My phone is nearly useless for a phone call unless i use speakerphone/headset.
#2 GPS/Compass calibration: I've tried calibrating apps on both phones but they still aren't as accurate as they used to be.
#2 Truedialer removed: I've tried all the techniques to remove/replace it and none of them work or cause rebooting.
#3 Headset volume: quite low, sounds like it's at 30% when at 100% on the slider
#4 Random reboots: Just yesterday i used "OK Google" to set a 3hr timer and as soon as the timer started it rebooted the phone. Another instance when it randomly rebooting while locked in my pocket. It seems to randomly reboot about 2-3x/week
#5 Bluetooth: I stream Pandora/Spotify/AIMP/etc over bluetooth in my vehicle. Pandora via the radios "Pandora" function (not sure what this is called, phone shows "Pandora - Accessory" when streaming) works flawlessly. But if simply using bluetooth connectivity it will show song info for the very first song and never update again. When i was on XNPH44S track info would fail to update maybe 1 out of 6 times.
I did completely clean installs on both phones. I'm tired of updating and getting everything reinstalled and back in order like i like. I just want something that works.

I've tried nearly all the ROMs including Resurrection Remix, and I find CM13.0 by sultanxda the smoothest and the most stable one.

Awesome! I use a few of those myself. I really need Boxer (Nine) Exchange Policy Cleaner to be compatible. Can't live without it
I'm just going to give CM13 by sultanxda a shot. Backing up now...
Just seen that AdAway isn't working due to a bug. Ugh! I think i'll wait on CM13 until thats fixed.

'N' icon in status bar

I have disabled NFC and all Android Pay/Samsung Pay apps, and still the 'N' icon still appears every now and then, and it will only go away if I restart the phone.
I notice that after a night of charging that most times I wake up and see the icon. I can't remember another situation when it happens, but I'm not using wireless charging so it's not being used. Does anyone know why this icon appears after disabling NFC, and how I could prevent it from doing so?

No, it's stock M. It's the AT&T variant G930A, which does not support root yet.. I'm wondering if there is any other app or something I could be doing that's dependent on NFC, but like I said I can't even turn on NFC if I wanted to, everything's been disabled which a package disabler.

...Clearly then its witchcraft, Voodoo, or the 'Ghost of Near Field Communications Past'... Considering its a phone though, who you gonna call?
In all seriousness, backup and try a full reset after you go through all Settings options fully; try restarting it as well before factory reset. Shouldnt be doing that. I have an S7 Active never had that issue but it would drive me nuts.

Since this reply found out the G930A is rooted now! I don't know where I've been the past week. Anyway, thank you for your help, I'm gonna do a backup and root and freeze the apps. See if that helps.
