[Q] GPS + 3G doesnt work. - ZTE Z7, Z7 Max, Z7 Mini

Hi mates. I've reinstalled my firmware to new one. And my google maps, or any other non-offline maps stop to work thru 3g (EDGE doesn't matter). Only works if Wi-Fi connected. I've moved to old one version of firmware - where everything worked fine (1.59 russian translation). But... Nothing work.
I've found some interesting thing - if I turn off GPS, it gets the traffic jam info, routes and etc. If I turn back - nothing work. But when I go wifi - everything ok.
Can you please help me in solving of this issue, because phone w/o maps is nothing?
Many thanks.

ok, map works with second sim card, but doesn't work on first.

[Q] GPS problem

I have a problem with GPS on my Hero.
GPS has a fix within 20 seconds and all seems to be fine.
After some time my navigation software stops and tells me it lost GPS.
In the taskbar GPS is still fixed.
i tried already lots of things:
- Different radios
- Complete wipe (including format sdcard)
- Different roms (2.1, 2.2 and 2.3)
- Different navigation software (Igo, Navigon and Google maps)
- bluetooth on/off
- data on/off
- wifi on/off
For now I am out of options.
I hope that someone can help me with this problem.

[Q] Loss of Data Connection

Hey Guys,
I unlocked and rooted this weekend, no problems. Running GB 2.3.4 and LauncherPro Plus. Everything was working fine, until this morning.
The data just stopped working. I spoke with my carrier here in Sweden and they sai the network is working fine, it must be something with my device. I re-input the APN, and still nothing. It works fine on WiFi, but if I switch WiFi off or leave my apartment, I can't get any data. The phone calls work perfectly too, so it's just data.
Any advice? Recommendations?
Thanks
*EDIT*
For some reason, my phone decided to turn off Mobile Data under connectivity. Simple solution, but have no idea why it turned that on!!!
Thanks anyways

Did you install or have the new Market pushed to you?
It causes data drop for a lot of people.

Hey CaelanT,
I have the market, but it's the one that came automatically. How do I get the market you refer to above? Or are you saying stay away from the new market?

Google Talk offline when on WiFi

Hi guys,
Me and my girlfriend have both a Samsung Galaxy S2 running the official ICS 4.0.3.
Since the upgrade to ICS, Google Talk won't connect on WiFi anymore.
When I use the 3G network, Google Talk works fine. As soon as I connect to any WiFi network, GTalk goes offline and I am unable to send/receive instant messages.
As I said, me and my girlfriend have the same issue! And it appeared only after upgrading to ICS.
GTalk version is: 4.0.3-239410 (330)
I already performed a factory reset of both phones and also of my home router.
Any other internet application (Google Play, Internet, Facebook, etc...) work fine on WiFi.
I have also searched the internet but there are only a few others affected and there is no solution provided to their problem.
Solved
Hello again!
As I said, me and my girlfriend had the same problem. 2 days ago, the battery of my girlfriend's phone went empty and the phone turned off completely. We never tried to turn off the phones completely until now.
After she turned on the device again, Gtalk started to work also on WiFi.
Then she told me that Gtalk is woring again and I restarted my phone.....of course it didn't work for me. Then my idea was to also turn off my phone completely. After turning it on again, BOOM !! Gtalk started working also for me!!!!
I have no logical explanation for this, but I am really happy that I can use Gtalk from home now, when connected via WiFi.
So, reboots didn't help, but complete shut down did help.
I have the same problem on S3. My GTalk also started to work after turning off my phone. But then I went out for a while and phone was connected to 3G. When I came back there was the same problem again, phone connected to Wifi and GTalk offline. In this case turning off helps again but I think it isn't best solution for this issue.

I have just bought S3 few days back . Its with Jelly bean 4.1.2. I am facing the same issue. Notification works fine in mobile network but not in home WIFI. The problem starts only if I change twice in between wifi to mobile ( wifi -mobile -wifi ). I am using notification for Facebook messenger and Gtalk. I tried to do factory reset or hard reset or tried in friend's WIFI but nothing works to that problem. Only i thing I see, it works if I reboot the phone then the notifications start to work again in WIFI also.

GPS not searching for satellite when mobile data is on

Hey everybody
I hope I can get some help from you guys.. I got this issue that I started to get into the running and started to need more of my gps to track my training and Ive noticed this weird behaviour of my gps.. It just wont even search for satellites whenever the 3g is on (you know the alert that says searching for gps).. installed the GPS checker to see if there was no satellites or something but it wont even search for them whenever I have the 3g on.. I found that the GPS works only if I disable the Mobile Data and restart my phone.. So I cant have both at the same time.. the minute I enable the 3g data it stops working and I have all the GPS options checked at the configuration and the wifi 3g assist.. What could be causing this?
Please let me know if some of you guys have some issue like this.. I have JellyBam 9.0.0 cyanogen mod based 10.1 and baseband XXXKI4

If you don't have this issue with a stock ROM, its probably a bug in the Jellybam ROM. Have you done a clean install? Since Jellybam has been banned from XDA, you probably won't get support for that ROM here. Maybe you should try contacting the dev of the ROM on their forum.

I tried the Omega stock V24 and had the exact same issue..
There's a number of GPS 'fixes' on here, I suggest you search for the threads containing those fixes & try some of them.
Hi!
I just want to share my workaround having same problem as this. After configuring my gps.conf as i've posted here: http://forum.xda-developers.com/showthread.php?t=1239713&page=77, all went smoothly and fast GPS lock for just about 5 - 15 sec, even on a cloudy or rainy day. Then last Tuesday morning, as soon as the mobile data got connected it cuts the GPS. In short, GPS & mobile data won't run simultaneously. I ran a series of reboot, shutdown, clean up... then as much as i don't want to, i ended up reflashing/reinstalling everything but to no avail! Now, since everything is fresh w/ my S2, but still had same problem. I now zeroed in the problem to how my mobile data connects. I didn't think of this before because everything works perfectly fine. Anyway, this time i changed the Network mode from "WCDMA only" to "GSM only". Finally! it works! problem solved.
So far as of this writing, both the GPS & mobile data connection are working simulteously. Only drawback are: (1) I can't browse the net using the "GSM only" mode because of the bandwidth limitation, but works ok w/ Waze app. (2) If i switched & connected to mobile data using "WCDMA only" mode, i need to switch again to "GSM only" mode & restart the phone in order for the GPS to works again.
I don't know, but i'm thinking if our telco here has something to do why I had this problem. Maybe they change some configuration... I dunno.

Hi,
I have exactly the same problem. Searching forum and the internet without results.
Last week I spent a lot of time with my SGS2. The problem occurs when gps and mobile internet data are used at the same time, but only when the phone use 3G or H+ standard.
When mobile data are transmitted on E/2G there is no problem at all. The issue with gps is that when I drive car and I'm in one location at the city (every day at the same place) the gps icon disappeared and no navigation at all. This is quite big square around 2x2 km. After I leave the area I have to turn off and on the phone and everything works ok, even when mobile data 3G/H+ are transmitted.
So described problem occurs only at the specific area. I don't know what cause the issue. After next researching I discovered, that gps disapeared ONLY WHEN THE PHONE USES UMTS 2100 MHz. In the service menu I mark only UMTS 900 MHz and the gps works very good. This time mobile data 3G/H+ are used simultaneusly with gps and everything is ok.
So the problem is olny when we are connected to BTS at 2100 MHz and only at the specific area. It seems that some kind of 2100 MHz signal intereferences wiht gps circuit maybe. I'm not a proffesionalist, I only suppose that.
Maybe somebody will find the complete solution with that.
My problem is at the cetral of Poland. I tried a lot of firmwares, modem drivers, gps.conf modifications. Nothing. Zero results.

Hmmm... it seems our telco here has something to do w/ my concern. Today, simultaneously my S2's GPS & 3G/H+ are working perfectly fine. I didn't do any reconfiguration w/ my S2, i just tried to switch how my mobile data connects, from "GSM only" to "WCDMA only".

[Q] In Europe, no GPS fix, why? And how to resolve this?

In summary (due to limited/slow internet access via wifi)
* Phone is a stock Samsung Galaxy S2 - v4.1.2 (UK Three network stock ROM)
* I'm from the UK and GPS works fine over there.
* I'm in Europe for holiday and GPS does not work at all.
Changes so far:
- Changed SIM card
- Added new APN, which includes this line for APN Type, which is default,supl,mms,agps and while Roaming Data works fine, GPS is not connecting at all (e.g. Google Maps, Co-Pilot, etc).
Using an app called GPS Test - it CAN find sats (up to 5 or 6 different sats) but NEVER get a fix at all.
Used an app called Fasterfix and set the server to Europe (I have root) - still no luck.
It CAN find a fix (well sort of, location is incorrect but is close by) if I enabled WiFi from our hotel. But useless when I'm out and about.
What else can I try to resolve this as I will need to use GPS in the next few days time (driving using satnav on my phone)
I have tried to do a search here but the hotel's wifi is pretty crappy/slow. :/
I'd be grateful if anyone could help me to resolve this.
Many thanks!

Flash a new rom!
-Root the phone via CF-Root or the App "Framaroot" from XDA , then install CWM through ROM Manager.
-Then download the ROM.zip you want and install it in CWM.

Thanks for the reply, but in case you've missed it, I am in Europe... I cannot risk doing it in case I brick my ONLY phone that I will need for the rest of my holiday. And I got sucky wifi access to download anything anyway.
BTW, seems overkill to do this... does it REALLY work? If so, why does it work when my stock ROM does not work? I'm just curious...

Oh , sorry.
Try to make a backup via GO Backup (best backup without root acess).
Then make a factory reset and restore the backup.
me too past two day.
I tried many rom: CM 10.1, 10.2, stock 4.1.2...but get same problem.
OK. Here's what's always worked for me so far as GPS is concerned, obviously YMMV & there's no flashing/risk of bricking your phone involved.
If you don't already have GPS Status, get it from Google Play. Go outside to a place that has good line of sight in all directions. Turn mobile data & GPS on & fire up GPS Status. Go into tools/manage A-GPS state & reset A-GPS XTRA Data. Then go back into the same setting & download new ephemeris data (which is essentially tables of satellite positions/where they'll be & when), then close GPS Status. Turn off mobile data & put the phone into flight mode (leave GPS on), then fire up GPS Status again. Wait for as long as it takes (normally not more than 5 minutes) for it to get a good/accurate fix (down to a few mtrs/with plenty of satellites).
Once I do this, it's always enabled me to get accurate/fast fixes for anything up to a couple of weeks until the ephemeris data gets old, in which case you repeat. Obviously if you have network connectivity this will help getting a fix, particularly in 'crowded' urban areas (cities/lots of buildings/poor LOS).
Edit - Also, if the above doesn't work, try this. I understand your reluctance so far as flashing anything goes, but you either want your GPS to work or you don't. Yes, it should 'just work', but there's lots of things in the world that should 'just happen' & they don't for whatever reason. This is how it goes with smartphones. The GPS on the SGS2 is particularly notorious for issues that simply can't be resolved easily for some people.
Flashing another rom or kernel may/may not work, if the GPS drivers are messed up, doing so will give you fresh drivers & may fix the problem if that's what's causing it.
