[Q] No GPS-Fix

Hello there,
I have a huge problem with my GPS, I searched the forum alot because of this, but wasn't able to find my exact problem.
first of all here is my problem:
I can't get a GPS-Fix. I used some apps like GPS-Status and I can see like 3 - 8 satalites in range, but still cant get any fix.
here is what i tried:
-flashing ROMs like hell (MIUI, ICS, Darky's, Stock)
-used many apps like "fasterfix" "gps aids" ect. did not worked out for me
-factory resets
-dif. gps server
-waited half an hour, clear sky, driving in my car 70km with gps on
you guys have any solution for my problem?
is it hardware? and if it is hardware, why am i able to "view" satalites?
Thanks, Karl

Download "GPS test" and stay on steady one place, enable wifi or 3g go to settings of GPS test and hit update AGPS, go back and wait till you get accuracy (meters) activated and gets as low as it can be (30m-5m is ok). Now only you can go in car for 70km....
You can download "gps.conf" of your country reason to get fast gps locking search here in XDA

This is no help, as i said, i testet it with several apps, GPS Aids is nearly the same program. i see a lot of satalites, but my signal stregh i too weak, so i don't get any fix.
without a fix, i can wait years to get a accuracy meters.

What Rom/Kernel are you currently running??
Under MIUI Mintberry Edition, I had a similar problem... my magnetometer was also affected.
I Solved it by:
1) flashing platypus kernel
2) editing the NTP-Server used to "europe.pool.ntp.org"
3) install google skymap
After that GPS and Compass behaved normally.
Average time to get fix (with agps) about 10 seconds

atm i'am using teamhacksung's ICS build 14 with derteufel's kernel.
ROMs I had:
MIUI (many versions) stock - Kernel: glitch(v13), platypus(r17 - NEO)
ICS - stock - kernel: glitch pre 14
Darky's ROM
I used GPS Aids and fasterfix. in these apps I changed the NTP-server already
to check GPS i'am using "GPS test" from the market
even if i have 10 satalites in view, i dont get a damn fix

How much strength of signal you get on GPS test ?
If it is low you wont get GPS lock !
Next, take out back cover and press gently to the rod like thing next to volume controller and see if the strength of signal improves (if it does your GPS antenna is loose)
By the way where in the world your location is?

I have an average of 8-12 of signal stregh.
i think only a hardware-fix can help to fix it. so screwdriver out and pray

Most stable ROM/kernel and reception/3g problems

I'am currently using Darky's ROM Extreme, the newest version. And well, from the moment I started using it my internet & reception started to work very poorly. Connectivity to 3g is dying almost always (And I live in LONDON. How's that possible?) and reception bar's jump from one to max frequently. I am not quite sure that this is Darky's fault but well - when I was running stock ROM + speedmod it was just perfect.
So yeah two questions from me:
1) What's the best ROM in the matters of 3g and reception? It also need's to have the tether function (all ROM's have that right?) 'cause I'm using that quite a lot.
2) If not because of the ROM, any idea where from my problems might be coming from?

Try putting in #9900# in keypad
Disable fast dormecy and exit (may need to do this everytime you restart phone)
or
search the #197328640# code on here I use Ario Rom as I dont like ICS type roms
Its stable fast and no issues with 3g or wifi..
..and it has tether w/semaphore
See if that helps.

gt-p1000 gps problems

hi all,
I was just wondering if I was the only one with gps troubles.
I tried stock rom, overcome, ics miui, jb aokp, but rarely got satellites detected.
I once got some connexions while using tomtom but about 20 minutes (discontinued) on a 2 hours trip.
with some test apps I got 3 feeble satellites signals.
Does someone else had so much trouble ?
(I trying some gps fixes I found but just wanted to know if I was the only one)
thanks

you are not the only one

No you are not.
Did you GPS work at all?
Mine did and then stopped.. here is what I did before it stopped.
I rooted it with ODIN (ages ago)
for ICS I followed the widely available instructions to get ICS (How to install Stable ICS 4.0.4 on Galaxy TAB P1000 [CyanogenMod 9 Stable]) and everything worked well. Needed a different camera app but the GPS worked reliable and FAST.
When JB was available I used the ROM Based on Jelly Bean 4.1.2 Platform. This is the official CyanogenMod 10 Nightly but had issues with Gapps and did not have time back then (xmas time) so just restored my nandroid backup. And to be honest I have no idea if the GPS worked after that. I think I used the iPhone more for GPS stuff until March.
Fact was it did not get any satelite at all, only location is via WIFI.
My hypo was that I may have missed something or the nandroid backup / restore does not include all files.
To fix it I looked for a later ROM and used JB. I used the Android 4.2.1 CM10.1 for Samsung Galaxy Tab 7 P1000 [Filename: cm-10.1-20121229-EXPERIMENTAL-p1-cdesai.zip] and Google Apps [Filename: gapps-jb-20121130-signed.zip] and that rome is reported that GPS works (but remember it did not work before i used this rom)
All went well and the rom works with all other features but did not GPS and I still have 0 satelites with either GPS Test or GPS Fix.
That is when I found your post.
I had a good dig around XDS and well GPS issues are plentiful, but not quite like the one you or I experience.
It seems that you at least get "some" satelites which is an improvement over none.
re-stocking did not solve it for you so I may save myself the trouble.
that said, my only thought is the GPS module packed in and that is why I get not a single satelite...
did you get anywhere?
TIA

hi there,
for my part, I bought this used tab some month ago. I didn't really liked it in gb, so almost immediatly tried to root it, changed recovery and rom, but never tested gps then.
I actually use miui ics rom and tried gps once. on a 2 hours long trip, sunny weather, nothing to disturb gps signal, I had 20mn of signal and not in a single straight connexion, but only just 1 or 2 mn from time to time.
I tried restock, but not bettre, even my chinese tab is more efficient. I'm still trying to understand and looking for answers but I nedd to restart my searches all over, too much things founds and now I'm quite lost.
The only thing I remember is that someone picked up gps files from his old samsung gsm and copied them on his GT as they had the same system.
I'll try to find that back, and maybe I'll try with my htc as they're all two on miui.
I'll send infos if I find something working

The same problem

Sorry for my english!
My GT-P1000 was to repair because it was unable to read the internal memory! After that I never tested the gps and rooted the tab with CM10.1 TWRP 20130802 Kernel 3.0.88 v1.35 (cm-10.1-20130802-UNOFFICIAL-p1)! I tried gps, but there is no gps signal and there are no satellites found!
Did ypu solved the problem?

no, still not solved it, I suspect some hardware problem like gps chip dead, gps antenna unplugged or broken, but as I had troubles with electronics thèses days, I will wait to open my GT

install apps like Faster GPS, GPS Fix or similar from Play
define your NTP Server and load XTRA data (table of current satellite position)
this will help you!

Location using WiFi and mobile network - not working

Hello all,
I have the S5 Mini Duos (SM-G800H) with Android 4.4.2, rooted, everything works nice, good battery life, except the following:
Location does not work indoor and some times in the car. GPS can lock on satellites when in open sky but sometimes in the car the signal is lost. For that times the phone should take it's general location from WiFi and mobile networks, which it does not because when I set the Location mode to "power saving", disabling the GPS sensor, the phone never shows an estimate location (a large blue circle in Google Maps), in fact Google Maps gets a very poor location overall, even when outside and GPS on, the location is not precise, the direction of my movement is not pointing, I only use Waze and it works but it works so much better on an iPhone, in car or inside when I try to check-in or search or Google Maps, I can't do anything inside with the S5 Mini.
Since I am trying to get a location from WiFi and mobile networks I guess it is not a problem of GPS sensor. What can I do to have a location (general location not accurate) inside using networks? Should an update to 5.1.1 can cure this? Can I try something before the update which can be tricky to do as there is no official release yet?
LE: Baseband version: G800HXXU1ANGF / Build number: KOT49H.G800HXXU1ANH2
Thank you!

In my case after updating to lollipop (stock) everything worked fine
Try to update might work as well

Hi all, I have installed 5.1.1, TWRP and rooted using the checklist here and yes it now takes the location from wifi&mobile network.
Still no improved location on GPS (in the car with Waze still do not show the triangle moving as it should do with a good 3D location set).
5.1.1 is a good experience overall, much improved notifications, speed is also good, battery life good with some tweaks and killing some samsung and google apps.
But, this morning my phone (not touched) said it is not rooted anymore (when trying to check wakelocks), and when I tried to restart it started to boot loop. Had to do all the installations again. Hope will not happen again.

Hi all,
After a few days ago I have reinstalled again 5.1.1 and rooted it, today in the middle of the day when trying to launch Titanium Backup, the root was gone again. Now it is loop rebooting What is wrong? The 5.1.1 build, the TWRP or the SuperSU?

Best ROM for playing Pokemon GO

Hello,
what is the best ROM for playing Pokemon GO on this device? I have used CyanogenMod 4.4.4. custom rom, but when im playing the phone laggs and sometimes crashes, and android system wastes too much ram memory (about 400-500 MB, almost half). The GPS also doesn't work well (in bigger cities it works but not precisely, in rural areas it doesnt work at all). I tried to play on other roms, but device fails on safety net check, so i can't play.
So, does anyone play Pokemon without any problems and on which rom?

No, it has to be at least Kitkat or newer versions.

You're lucky. I've tried about dozen of roms but none of them work. I always get the 'unable to athenticate' error. What rom are you using? I'd be happy with that.

I do not know the minimum requirements of Pokémon GO. But official CM 10.1.3 has the best performance I ever tried. In second place comes official CM 11. You can try some kernels to improve performance too. I recommend Werewolf's and Iodak's kernels.
