I have this rather annoying issue on the Desire. The phone is brand new, i bought it upon release. The problem is that whenever i enable GPS on the phone the Mobile Network connection gets killed. Attempting to reactivate it by switching mobile network on and off does nothing.
The only way to get the mobile Network back up again is to switch of GPS and reboot the phone.
Has anyone else encountered this problem? (i searched the forums, only found one user on these forums)... It could help me figure out if this issue is limited to my device...
Regardless, I already contacted HTC on this matter, i will post their response here as soon as i get it.
Thanks!
Odd. The only thing that springs to mind is that somehow the A-GPS is messing with your network. Try disabling A-GPS.
Is the phone bought from the network provider? If so, any network incompatibilities is their responsibility. Or even if it was store bought, you have reasonable expectations from HTC that it should work with local networks. If its gray import however, you're probably on your own.
Yep same issue with my HTC: When GPS enabled -> No more data transfer.
I'll also send a mail to HTC.
I reset the phone to factory settings today and to problem is now gone. My best guess is that the issue was caused by a third party app i installed (i'm not sure however, since all apps are sandboxed).
I installed two apps that made use of location services: GPS Status and Trapster. I'll download them again to see if they are the cause of this problem.
Please post back here if the factory reset works for you. This could help other people that experience this problem.
BTW, does anyone know of way to read error logs of the device? The OS must have software errors logged somewhere...
Thanks for the replies!
Received an answer from HTC (sent a mail about my Data Connection Problem few days ago):
"Thank you for contacting us in regards to connectivity on your Desire, I can help you with that. This issue has been reported to our developers for investigation and we hope to have a solution available soon. I trust that this resolves your query"
Hope also this "solution" will be available soon...
Guys,
I did a hard reset (return to factory settings ) on my Desire today and guess what:
Both my Data problems (no data after use of Wifi and or GPS) are gone !
Tested several times Wifi & GPS , also did a reboot and tested again, all seems working again, no more 3G data problem anymore.
So I guess one of the extra apps I installed caused the 3G Data Connection issue.
I'll reïnstall them one by one to see if I can catch the "guilty" one.
I also hope that problem doesn't return after a while without a cause.
Hi to all,
I have just officially Mango updated my LG Optimus 7 four days ago. Overall I'm very pleased with this new OS version, despite that in my country (Mexico) some services don't work yet (bing vision, artist art in lock screen, turn by turn navigation with bing maps app, etc.).
I started to think that WP 7.5 was almost perfect, until i discovered a 3G connection issue that didn't have before. Since yesterday I have noted that sometimes my 3G connection doesn't work after i turn it on: the 3G logo doesn't appear near to to the signal bars and, of course, i can not navigate in internet using internet explorer. I also found that this issue gets temporary fixed if i reboot the phone.
Using the search tool in this great forum, i've found that very few people had this same or similar issue , but it was before Mango update!. Since it appears that nobody got a solution at all (other than rebooting the phone or turning on-off airplane mode), i would like to know if anybody here have had this issue after Mango update and if there is a better solution than rebooting.
Thanks in advance for your help, have a nice day and keep enjoying this wonderful new OS.
P.S. Sorry for any writing misspell, English is not my native language
Hi, I was in Mango before and now i have received the official update as well. I also saw that the Bing search page does not fit the screen and also does not contain the bing audio to identify songs. Does it happen to you as well? Regards and thanks

reseat yr sim card if u have connection issues...
Castrow,
The bing screen fits well on my phone, however, i don't have bing audio service too. I hope this feature (and others) to be available soon on our countries.
Magpir,
Thank you very much, i'll try your suggestion, maybe it's the sim card altough i never had this problem until i upgraded to Mango version.
I'll post again if this solution works.
Best regards,
I had this issue in the past, until the NoDo Update was released!
After NoDo, ISSUE SOLVED! Internet connection outside Wifi perfect, and it managed perfectly. BBBUT
Now mango is launched! WTF! The problem is here again! After mango, the 3G connection is wooooooooorrse! Who else feel the same situation? Anyone that felt, could solve it somehow? It seems that drivers are not updated, I don't know. Please, don't say that it may be my Carrier! IT IS NOT! =)
Let's find together the solution guys!
Hi ralex3000,
Let me tell you that i've followed the Magpir's suggestion and it has worked at least during a day. I haven't used the 3G connection very much but i can tell you that every time i turned it on, always had a clean and quick connection.
This is what i did:
1.- Turned off the phone and pulled out the sim card.
2.- Turned on the phone without the sim card. (Why?, eerr...i don't know!)
3.- Turned off the phone again and reinstalled the sim card.
4.- Finally, turned on the phone.
Please let us know if it worked for you. I'will update if anything else occurs (i hope not).
Regards
i don't know if this is a feature or a bug, but:
when the phone's ringing, you can hang up by pressing the volume rocker up or down.
Bad news guys, the issue appeared again, so reseating the sim card is not a solution.
I'll keep searching forward.
Boredtoday
I'll try to test the bug/feature that you are experiencing, it must be a feature, maybe we should go to the official wp7 page to learn more about it.
Best regards
is your optimus sim unlocked? i have some issues in my sammy focus, and to fix it, i just enable ADC flag , reboot the phone and all works fine. Here is a thread to made this in LG Optimus 7
bing voice

WOW, I tried your fix and my TWS went from 52% as well down to 0% last night. My battery, which previously drained >30% while I slept, now only drained about 9%. I'm keeping my fingers crossed, but I think you may have found the fix.
Now for a more permanent solution... Do you think we should contact Samsung about this?

I don't have the problem with the 3G connection on my LG Optimus 7, but other than mails and some random search I don't really use the data connection too often to assure that I don't have the problem.

When I had the same problem on my omnia 7 I solved changing my Network Operator and then resetting it. To do that Samsung has an app called Network Profile.
Hi there. I own an unlocked, rooted t 989 Samsung Galaxy SII which I bought in the US. I recently moved to the Netherlands, and got a new simcard with Vodafone. The problem: I can't get my data to work.
I have tried (almost) everything, so prepare for a read. Here's the list:
- Sim card is fine, I tried it in a old phone and 3G pops up instantly
- Rebooted, pulled battery, turned mobile connections on/off, handpicked network, etc, etc, all the basics.
- Got the APN settings from Vodafone. Tried them manually, resetted them, automatically, turned it on, turned it off.
- Going online through Wifi works.
- Under settings-Status it reads under Mobile Network State: Disconnected. But I know that the phone detects the network correctly. It can distinguish between UMTS and GPRS here.
- So there seems to be no trouble with the phone being incompatible with the network. I read online that other people had NO trouble using their T989 in Europe.
- I tried inserting my old American pre paid T mobile sim card and turn roaming on. No luck.
- A lot of other people with the same problem tried to link it to Easy Battery Saver. I tried updating, uninstalling and going into its settings to find out what it could be, but nothing.
The last thing I can still try is to factory reset, unroot and try to get the phone to its most original state and see what it does. But before I triple wipe all my contacts, pictures, apps, etc, I want to make sure I did absolutely everything to try and fix this beforehand. Being a noob here, I can't post any links but I trust you I tried.
The people at Vodafone are of no help whatsoever. I hope you geniuses could help me any further.
[Edit] And sorry for posting this in General Chat. If a mod could move my question to Q&A I'd be most thankful..!
I am having the exact same damn problem! it started with being unable to send a simple text message yet having data. now it says it is searching forever

Try flashing a different radio/modem then an american one?
@decko5 Nice to see I'm not the only one, but that doesn't help us yet .
@doug36 Besides the fact that I'm running a stock ROM that should be compatible with no issues, I'm not sure how I'd do that. I can flash a separate part of the kernel? That sounds like a very tricky thing to do.

It's actually pretty easy. You can flash most radios via ClockworkMod Recovery. I couldn't find any threads with a list of Galaxy S-II radios here on XDA, but I found one over at RootzWiki for you. http://rootzwiki.com/topic/2725-radio-samsung-galaxy-s-ii-radios-updatezip-updated-20-aug-2011/
Just find the corresponding one to your geographical location and carrier (Google is your friend) and follow the steps.
Good luck and hope it helps!
(p.s. you should definitely look to see which radio you currently have so that you can download a backup of it before you go flashing radios.)
Thanks for that very helpful post! I've raped and butchered Google, but I'm still having trouble finding out which modem I should download. There seem to be so many and the post on RootzWiki gives no guidance to which is which. Any wisdom on this? I'm in the Netherlands, so Western Europe, on a Vodafone network.
By the way. I fully wiped my phone and installed Team Kang's Juggernaut 5.. No luck, same problem. What I found really, really weird is that it was instantly in Dutch. (Which is ok, I speak Dutch) But I don't remember ever selecting a language. How does it know? Besides, I'd rather have it in English .
What I did find out is that I'm still using a old firmware, UVKID, instead of UVKL1. So I'm restoring back to my previous ROM and trying to update. I'll see what happens. If that doesn't work, I'm going to restore my phone to stockest of the unrooted stocks and try and update.
If that doesn't work, I'll have no option but to send the phone to T-mobile.
I'll try the modem update as soon as I understand what I'm doing . But it does sound promising. Thank you so much for your help, it's greatly appreciated!
Hi guys,
I've updated my firmware to UVKL1, still no luck. Anybody who can tell me which radio I should try on this Vodafone network in the Netherlands?
I am from India and had faced this similer issue with many of my android phones specially with captivate and infuse.......Here what i always did to connect data network.
Just uncheck the use packet data network box in mobile network settings and try to move out from that area (say u are in ur office and going back home) and check the data in settings.
This thing has worked for me always, I don't knw if its related to the OS or to the network provider but this has helped.
Have u tried any other network sim card on ur phone ?
An update for other people that might be looking for a solution in the future. It turns out to be a clear Vodafone problem. I tried a different simcard from a different network (both T-mobile Netherlands and KPN), and they instantly worked without any trouble.
I went back to a different Vodafone store in Amsterdam, and they were much more helpful than the first one. The sales guy told me he had seen the same problem with AT&T iPhones on the Vodafone network.
I called Vodafone, and they have been very nice to me. But they haven't found a solution yet and are looking into it. They see me registering to the network, granting me access, but still my data doesn't work. They've also told me that they will let me cancel my contract for no cost if they don't find a solution.
So problem remains unsolved, but at least there's some light at the end of the tunnel. I was close to buying a new 500 dollar phone... Americans going to Europe: Beware with getting a Vodafone simcard. Sorry to the Vodafone guys, but as for now, that's the status.
So to give closure to this issue (I always hate it when people fix their problem without telling the interwebs..)
IT WORKS!
After an initial terrible experience at the Vodafone counter, the headquarter tech guys have really been great to me. So it is indeed a Vodafone problem. American phones always give them a headache. They don't know what causes the problem exactly, but they do have a fix. It turns out that when logging on to the data network, American phones (AT&T iPhones, my T989 SGsII, and some other Android devices) sent some gibberish along that make the Vodafone server go cuckoo.
The solution was, miraculously, to sign me up (for free!) to the WiFi hotspot service that Vodafone provides, and then logging on to a different APN, being: office.vodafone.nl in my case.
Hope this helps anyone who's having similar issues.

ok the issue here is that some of the t989 are vodafone and some are USA network , now the other solution is that you flash with command prompt which there is a link to that tool im going to upload from the link i got it from . its also a clockrecoverymod , but this 1 asks you for deleting data user on the device and also resets the network includes USA/overseas though if your not customed roms
or any hacked roms , after flashing this device your basically removing any unwanted apps and cache that are hidden during network searching will be fixed bugs , put the simcard in slot but make sure that is a 3G/4G accounts, than its going to reboot the device automatically , it should be searching for service and also will be a circle with a slash on it where the service bar usually is , just wait about 1/2 hour to an hour maximum time let it do its thing , ok whats happening now to the phone is that is thinking with android network with usa and overseas market apps comparing both carriers network also gets the proper address for the custom rom or original kernel, froyo either 1 will get the correct network address and / VPN / and also will be adding both T-mobile/AT&T choose T-mobile dont go for AT&T cause it will research network configuration plus the phone its not unlocked for both its just a network passby to get correct WPN/VPN/clockworkrecoverymod .
Where is an fix?

@#11 That reads like gibberish to me
@#12 I think I posted a fairly extensive report on how I fixed this...?
I own a Mi Max Helium and from the first day I use it with open bootloader and Custom Roms.
After 4 Weeks of using the strange things began:
- I lost network sometimes, but most of the times it was back in seconds. (once or twice a day)
- then randomly the MiMax said there is no sim card installed. Ok reboot phone and everything was okay. (once or twice a day)
- then it happened every hour
- and then sometimes after some hours or some minutes - not replicatable
- as a last step rebooting the phone doesn´t help. I have to kick out the Sim, wait some seconds and put it in again
Ok I thought it was a fault with the custom roms.
Made a real big factory reset with mi flash tool and cleaned the whole phone like a new device after the delivery.
After the first reboot it wasn´t able to find any simcard (IMEI und EFS was okay), so I thought phone or SimCard has a defect.
Took a simcard from my girlfriend - everything was working fine. Took my simcard in the MiMax and curiously everything was working fine
Flashed Xenon HD Custom Rom and everything worked well the last 4 Weeks and now the whole Sh*t begins again in the same way like described above.
Wtf is that behaviour? Can anybody report similar things?
Using SIM-Slot 1 or SIM-Slot 2 makes no difference. Its not logical or reproducible for me
T-Mobile? There has been reports not only fo Mi Max but One Plus X and some other Chinese brands killing particular tipes of T-Mobile sim cards by constantly trying to write on them. Sounds exactly what you are describing.
Solution is call T-Mobile, they know the issue and should replace sim card with the right tipe.

Interesting. No I´m using a german multiple provider called 1&1 and they use Vodafone D2 Network here.
They also use Telefonica (ePlus & O2), but the reason for that behaviour could be the same. I will call my provider and hope the know similar cases.
Thanks for the advice so far :good:
Well I share you problem I am.from Chile and this started to happen after updating to official ROM 8.2.3.0
I tried for months to find a fix but in the end I've noticed in my country all operators started using 4g band 28 (700mhz aggregation) band is not compatible with my Max prime (helium)
This doesn't explain why the card is lost until rebooting the Phone though.
A good thing is to set auto turn off in security app at 7:00am then enable auto turn on at 7:10 am this way your phone will work in the morning and not lose any important phone calls.
Check out this thread
Do you have any similar symptoms? Can you search for networks manually? I can't

Hi, I've problems with my device I bought online. Mainly the cellular signal keeps dropping to 0 rendering the service to be unusable. I wanted to make a thread to know if we could fix this ourselves because I didn't want to send this back to the store.
Here's the list of failures I've tried:
1. Tried to insert my sim to either slots
2. Inserted another sim card
3. Inserted both sim card and tried to swap it's slots
4. Deactivated Volte
5. Tinkered with cellular data APNs. (Mainly copied the settings from my other phone)
5. Restored factory settings
6. Repeated these steps after restoring factory settings
Also, Whenever I'm browsing media and whatnot, the back button seems to trigger itself. (once or twice every 20 minutes while watching a video).
Miui 9.0.2.0 (Philippines, Globe sim card [Other networks have the same problem])
I haven't unlocked bootloader, rooted or installed custom roms because I didn't want to void warranty and waste my time and money.
I'm hoping we could fix these problems ourselves. Any thoughts of what I should do? Should I just return this?
my "no signal" story: after 3 weeks my new mi6 got no signal anymore. i read many topics on xda, and thought it might be a software issue. although i decided to head to my mobile provider and asked for help. i got a new nfc simcard which solved the problem till now. it seems there are some issues with old european simcards on new chinese mobiles. the simcard just crashes and you loose signal.

Thanks for the reply, I'm gonna have to try and change my sim. The back button is probably a defect. It's getting worse.
