Optimus 3D 3G troubles

Hello everyone,
I hope someone can help me because I am going crazy with my Optimus 3D My device constantly loses the 3G connection and so I don't get any notifications about new e-mails and Whatsapp messages. The icons for network strength turn white and even sometimes that happens with the wi-fi icon. I already tried rooting the device and installed a custom rom but I still have this problem. The problem mostly occurs in the office I work in as 3g and network reception is very low here. I see that the device switches between HSDPA, GPRS and 3G quite often and then most of the time loses the internet connection. It also does not reconnect when I walk around and get to an area with better reception. Sometimes switching to Airplane Mode and back helps, but this is not a very handy solution. I am really clueless where the problem could be. I am here in Frankfurt/German so normally there should be no problems with the network (I am on Vodafone). The only thing I could think of is my SIM card, because I had an iPhone 4 before and had to cut the card to the micro SIM size and now use it with an adapter. Could this be a problem? Also the app 3G reconnect did not solve this problem.
Has anybody a clue what might be wrong with my device? I am already thinking about getting a new phone
Cheers,
Andreas

Does it do that when goes to sleep?

I don't know when it loses the connection, could probably happen when it turns the screen off or switches between network speeds (3G, GPRS, HSDPA). It really is a problem for me that it does not get the connection automatically back. Currently it shows almost full network reception, the "G" icon with both arrows underneath (only the left arrow pointing up turns green from time to time), but it has no internet connection. I sent me a mail to my google account via my office PC haöf an hour ago, but still no message on the phone, that there is new mail

Just try a new simcard... my guess is that it will solve your problem.. could be worth the couple euros ..

I had similar Problems with O2 in Bremen.
That happens if the phone loses the 3g(h+) signal, turning of the data connection, and let that reconnect is enough, no need to turn on airplane mode than.
Try flashing the newest baseband version, and try the prometheus rom + kernel. I still notice that the same problem happens, but it reconnects again after losing it now, and i rarely notice it that way.
Maybe you could tell us your android version, and baseband version.

I had a similar problem when I used GB roms without upgrading my baseband.

Hi everyone,
thanks a lot for your answers. I have the newest firmware on it V21E and baseband is L6260_MODEM_SIC_01.1042.00. Problem is that it does not automatically reconnect when it loses the internet connection. I had this problem again the whole day. When I left the office for lunch it did not reconnect, so again I did not get the newest e-mails. Probably I will really try another SIM card with a different network provider. I never had this issue with my iPhone... Thanks a lot for the advices, hopefully something will work. Otherwise I need to get a new phone :/
Cheers,
Andreas

For me the 3g data service goes as it likes but to reconnect i have to restart the my phone. Tried many roms as well as kernels and finally using acura 3d Max 3.1 with titan kernel solved the problem. It doesn't give up 3g connection but if i switch to edge and back to hsdpa again i have to restart. Barry also lasts and have overclocked to 1.2 ghz

In the Dailer APP dial *#*#4636#*#* Phone info Scroll Down just above the turn off radio button Change from WCDMA Preferred to WCDMA only

Good morning (at least here in Germany it is morning *g*),
got me a new SIM card with a new provider yesterday evening and so far it seems to work fine in the office. I hope it stays like this, then the problem would be solved *phew* Thanks a lot for all your help!
Cheers,
Andreas

[Q] Nexus S suddenly lost connection to mobile network (can't call, text, use 3G)

My phone suddenly stopped being able to send/receive texts or calls and can't connect to the 3G network -- doesn't seem to be a SIM card issue because when I popped the SIM into an old flip phone, I could call/text. At first the phone looked as if it had full signal and was connected to 3G, but it wouldn't connect when dialing out and couldn't load any websites. I've since reset it (first a factory reset -- still had the same problem, so I did a hard reset) and now I don't even see any signal on the phone. It would work for a few minutes if I turn it off and turn it back on, but then it would suddenly stop working after a few minutes. Has this ever happened to anyone? Does anyone have a solution? Thanks!

How do I go about doing that? (and my wifi is working fine -- does that mean the radio is okay...?) Thanks!

network loss in nexus 4
hi , have u resolved your issue because I'm facing the same problem !

check that your phone is showing that you have a baseband and imei number

Yeah, either flash a new radio, or your IMEI number got screwed up somehow and it isn't registering on the network. Let me know if you need links to the Radio forum.

I've got the same problem now, unknown baseband & imei. anyone know how to fix this ?

Calling issues? Advanced Calling?

I recently got a GS6 and I'm having problems with calling/receiving calls.
When calling/receiving usually the other person can not hear me talking but I can hear them. Sometimes they can hear me for 30 seconds or so then they can't hear me anymore. I disabled and enabled Advanced Calling and restarted my phone and it seemed to work for one phone call. I only tested it on a short call though so it could of stopped working during the call.
I tried disabling Advanced Calling and made a call right away without restarting and the person could still not hear me. I did see my phone dropped to 1X during the call this time. Does it take time when switching off Advanced Calling for something to happen on Verizon's network?
Anybody else have this issue or a fix? I'd rather not have to do a full reset.
Thanks.
Edit: Just deleted dalvik cache and cache partition in FlashFire and it seems to be working. Will update if I have the problem again.

I was dropping calls regularly. I disabled AC and I have not dropped a call since. I would 'reboot' and double check to see it is indeed off

we had to call and verizon had to "program" some stuff for AC. Try that. worked on this end.

I have this same issue. It has happened to me mid conversation. It is annoying. I didn't have this issue with my G3. I thought it might be because I'm running a room that is debloated. I'm trying to hold on to this phone because I'm hoping the next update to 5.1.1 will fix this issue. If not I'm going back to LG.

With AC off you won't be able to talk and use data at the same time which is a deal breaker for me.

Did you have problems activating AC on your phone? If you don't have it added to your account you have to do that first.

I'm running CleanROM 1.5. I might try flashing it again to see if that fixes it. If not then I will try stock. The problem with 5.1.1 is that it probably won't have root.

Root stock, I have not noticed this issue and this week has been a big phone call week. Lots of long conf calls many times a day.

Thanks for posting.
I re-flashed CleanROM 1.5, so hopefully that fixes it. If not I will try stock.

Re-flashing CleanROM 1.5 did not fix it. I guess I will have to try stock now.

BTW it is quite possible that you are just in an error with bad signal too.

I guess that's possible but I have 2 bars on Band 4. I could try locking into Band 13 but that is congested at times in my area.

Bars are misleading, look at signal strength instead.

Around -105 dBm. You would think if there was reception issues the call would completely drop.

When I lived in an area that had a signal level of -100 to -110 I would sometimes have calls drop and Verizon stated I was in a fringe area and would let me out of my contract.

The thing is only B4 is that high. B13 is around -93dBm.
I planned on doing a test today to see if I stand by a window where I get better signal if that would help. The call went through fine today. I checked LTE Discovery during the call and it said I was on B13 though. Around 10 minutes later the phone was back on B4. I made a call then and the person could not hear me. LTE Discovery was saying around 114dBm. I moved maybe 4ft and the dBm was around 106 and then the person could hear me. If I move 12ft more I'm by a window where I get 99dBm.
So when I sit at my desk I can't make any calls and will have to get up if I'm on B4. I wish I could force the phone to use B13 during calls.
Another issue I had the other day was my phone was only connecting to 1X even though I was in an area that had good 4G. I've always heard Samsung had crappy radios. The only times I would get 1X on my last phone (Droid DNA) was when I was in the middle of nowhere. Wish I would of noticed these issues sooner so I could of returned the phone. :-/

Mobile Data won't connect after WiFi use?

I've seen this problem now about three times. At home only, I'll be on WiFi and then leave the house and will have to force airplane mode on/off to get the mobile data to work again.
I haven't seen the same problem at work.
Any suggestions?

Same problem, many others on android-hilfe.de experiencing it as well. Emergency calls only for me at least 9x a day. This is really ruining an otherwise completely fine experience.

Cannot recieve or make calls after new Nov 14 update

Anyone else having issues with not being able to make or recieve calls? After the update, if I try to make a call, it hangs up right away. No one can call me as well.

I have exactly same problem on my 2 Notes. I fix one by resetting phone app but second one not working all all.

I resolved my issue by turning off Enhance LTE, reboot phone then turning back on Enhance LTE.

YEP. That did it.. THANK YOU !!!!

Check the news about AT&T. Earlier this evening there was a nationwide outage with voice service. Apparently, all AT&T said via Twitter was to "restart your phone. It may take several restarts.". Typical AT&T customer service I guess.

My Wi-Fi calling seems to not be working properly. It is not as aggressive in low service situations like in the past.
