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] Connection issues with Wifi and Mobile Network

So I've had my nexus 5 for a few weeks now and I have two connection issues, one with wifi and one with the T-Mobile network.
Wifi Issue: I can connect to wifi with no problems, but after a while the wifi just stops working. It is still connected and the signal strength is good but I can't load any web pages or download anything. This usually happens if I'm downloading a large file from the play store.
T-Mobile Network: I usually drive though a couple dead spots on my commute where I lose service which is unavoidable. The problem is once I return to an area I know I get service, the phone has not reconnected to the mobile network. A triangle shows up in the notification tray saying I don't have service and I have to either search for a network operator or reboot the phone to get a connection. This problem doesn't happen every single time I lose service, but enough to be very annoying.
If anyone has a solution or suggestions they would be greatly appreciated. FYI my nexus is completely stock (using ART), I haven't rooted or unlocked anything...yet.
Thanks for your help

I have very similar issues.
I am on stock, unrooted and can't get decent internet through my WiFi even though my nexus 7 and other phones don't have an issue.
It also seems to struggle over 3g. I am with 3
I was considering contacting Google to see if I can replace the phone. I bought mine in November.

4.4.3 baseband messing up with TMo LTE

I updated my N5 to 4.4.3 through this: http://forum.xda-developers.com/google-nexus-5/development/flashable-stock-4-4-3-supersu-t2771010
could not wait for Google to update my N5.
My wife's N5 was updated through official ota.
We are both on TMobile. Same plan. Same zip code.
At home we use to have both LTE signal at 3 bars out of 4.
After the update I noticed this issue where both phones are connected to LTE but now we have 0 or 1 bar out of 4.
often I see No Network at all.
Changing to 3g or 2g will set the phone back on Edge or HSPA.
I think the new baseband messed it up.
Anyone else experiencing this issue on TMO with N5?
Any ideas?
Thanks

I noticed 0-2 bars of LTE at home but mine has always been like that.

i feel like i have less LTE bars than i did prior to the update. In some areas where I have always had LTE coverage, I have HSPA instead. At work I have less bars - I work very close to home (NYC, Manhattan) so i'm not sure if it a problem as a result of the update or service issues in the city - at least in my case.

Bars and signal strength are not necessarily related. The bar is just telling you what the software is interpreting, there have been tons of signal bar hacks that make it more or less accurate.
What I will say is that the LTE drops are something I've seen before even when I paradoxically had "full bars" on LTE only to suddenly have my phone not actually displaying a connection and then it would, after a moment, drop to H+.

Not to sound like a D1ck,But.(I feel your pain)...Finally someone else besides me having issues and I'm on sprint (insert jokes now)the same thing has happened to me my wife my dad my brother and his wife.All of our data handoffs from 3G/LTE hang.I/we have gotten worse LTE.You are not the only 1.I even adb fastbooted back to 4.4.2 to see if the difference is just in my head.It's not.4.4.2 gave me LTE back again.

I am thinking to flash back the previous baseband. Anyone reversed back to the old radio but staying with 4.4.3? I can tell you that the battery life is better with 4.4.3.

Are you seeing that the behavior of handoffs is different or are you losing your data connection more often than before?

I am also seeing emergency calls only in some places like my job, where previously I had 3 bar lte. But at home it stays with 0 to 1bar very unstable. I am convinced is the new base band. Tmo told me to do a switch from 3G back to lte in network settings. After that didn't work they told me to do a full reset to factory settings. Thinking to flash back to . 23 radio.

Both. The hand off is so bad I can't even verbally describe it.My singal drop is so bad I want to smash my phone.(but I want cause I love my nexus devices as much as my kids)

Wrong signal strength reporting on G920i?

Weird issue I'm having on a G920i. In Settings -> About Device -> Status, the signal strength is being reported incorrectly. When I first boot the device, it will show accurately and will vary from -90 dBm to -100 dBm when I am at my house, which is consistent with every device I've ever owned. However, after 30-45 seconds, it will start reporting at "-113 dBm 0 asu" and it will simply stay there and will never change, even as I move about. The number of bars in the signal strength icon on the status bar will even change, but in the Status menu, signal strength simply stays at "-113 dBm 0 asu" permanently. Connectivity seems to be fine--I have no problems making calls, browsing the web, etc. The signal strength in the Status menu simply seems to revert to and stick at 113 dBm 0 asu with no explanation or other impact on the phone.
For what it's worth, I've tried both the New Zealand and Singapore AOD1 firmwares from Sammobile.com. Same problem on both. I'm on AT&T in the U.S.
Anybody else seeing anything like this?

Yes it seems both the g920i and g920f all have this problem. Every single device. Please get in contact with Samsung about it, the more people that complain the more likely it will be fixed.

@mupet0000 & @phositadc I've seen you guys in a few forums talking about the Galaxy S6 SM-G920I signal issues... Mine is the same! Swapped 2 phones already and they have awful lte reception... I was hoping a different modem/baseband would help but it looks like it doesn't....plus a few soft reboots as well what's going on? Have you guys experienced any reboots? Can this be fixed with a software update?

OK checked mine and its yes your right. -113 in status however if you type *#0011# in your dialer you'll see the better reception reported. Interestingly this did not happen when I was on the Cricket towers(At&t). I just switched to T-Mobile and I now have the -113 status. My speeds are great but I can't side-by-side compare the radios to anything to know if there is a real problem.

No reboots here. I flashed the aod3 modem last night and things seem a little better on AT&T. On the aod1 modem, I was not getting LTE in a bunch of places that I've always had LTE before. I know the g920i has frequency support for AT&T LTE bands, and I do get LTE, but I must say so far the experience has not been as good as other LTE phones I've had. Not sure if that's the modem firmware to blame or the hardware itself. Probably firmware.

Hey all, I'm in the UK and I have the SGS6 edge on the 3 network here. I use my phone for tethering at all times as I do not have wifi in the house. with my SGS5 before this I could easily run my PC , Tablet my son mobi and his gaming PC all at the same time with no issue. The S5 would run a full signal and load very quickly HD content.
My brand new S6 is disapointing singnal wise from straight out the box. I noticed my signal level fluctuating up and down but very rare dose it show a full signal level. and as for teathering I am finding it very hard to live with.
I will be suprised if Samsung sort this out with firmware. I just had a 150 MB firmware update yesterday and my signal level is the same.
I remember my Nokia N96 having this same fault, and although it was all over the internet back then, Nokia did nothing in all the firmware updates I had. I was going to sell my pristine 7 month old S5..... but I think I will hang on to it for now.

Hey guys, I am on the latest OTA released by Samsung (AOE3 built May 7th) and the problem is still not resolved. LTE signal still awful and LTE signal strength still -113. So far so bad. I have contacted Samsung again, and tomorrow I have a phone call with their support where they will remotely access my phone so I can show them the problem. I will show them and see how it goes, and I'll report back here.
I will make it clear to them that the signal strength is worse than my 2 year old S4, and I will demonstrate the incorrect signal strength value to the support agent. If they tell me it's a non issue or they make some silly excuse instead of investigating, I will simply sell the S6 and get another phone.
This is a huge issue and I'm disappointed that there aren't many people noticing this or reporting it to Samsung. The more popular the S6 gets, the more people will notice that their old phone holds a better signal.

I think it is a widespread issue... I always have 1 bar lte and under my signal status it say - 113dbm which is zero service... It never moves... I'm gonna try custom rom and see if that help but it obviously a antenna/modem baseband issue... Also someone mentioned it could be because the Galaxy S5 uses Cat 4 lte and the S6 uses Cat 6.....its very disappointing! Hopefully it gets fixed or I'll return to the S5...i really want to like this phone..... But Samsung is making it hard to

I don`t think there is anything wrong with the signal. even if I only have 1 bar the phone is perfect during calls and my LTE/4G download speed is even over the provided speed my carrier provides, I think it`s just a bug that it`s showing less signal then what it actualy has.

This is true. It's simply a bug that shows the wrong signal strength - mine shows -113 but I'll have 3 bars so that makes no sense. However, if you ARE getting a bad signal, that is a different issue altogether.
(btw I started a thread about this already several weeks back)

Spoke to Samsung on the phone, they didn't need to remote access my phone to see the issue. They had an S6 in their office and they told me they saw the signal at -113dBm just like mine. They say they have passed this onto the relevant team and hopefully it will be fixed in an OTA and I should stick to the United Kingdom BTU firmware (the correct firmware for my region).
We will see if this gets resolved. They definitely know about the problem now and have seen it with their own eyes, so I'm hopeful.

Ok.. Thanks... I already read through that thread too... Been trying to figure out if it was just me or alot of people..... Seems like the 920f is getting more updates that us.... 920I......The latest is AOD3 right? Today I'm gonna flash a custom rom for 920f and see if there is any change....
*edit* just checked Samsung live update... AOE3 was just released for 920I for TTT I guess is a country called Trinidad and Tobago... But that is the firmware I've been using.... Hopefully this will help... Let Ya guys know
*edit #2*...ok guys just updated to AOE3.... Bars still show low but the signal status is working and it's showing that I have a better signal than with *#0011*... The - dbm and asu is now extremely close to my S5... So in conclusion the signal is strong it just doesn't show it in the bars like previous Galaxy's

Note EDGE data connection not working

Hi,
I have a note edge n915G. It was passed down to me. Previous owner never uses data connection.
When i took over, i realize if i switch on data, my signal seems to drop a lot from H+, H to edge and then emergency call and no signal. It connects and disconnects constantly.
Also, it NEVER connects to 4g eventhough i have the right settings and my 4G is working on my other phone.
Flashed CM, stock rom from different n915g country and etc and it doesnt seem to solve the problem.
Could it be a hardware problem? Now i live in malaysia and this phone was bought in Singapore so it'll take quite an effort just to send it in for warranty. Thanks in advance.
edit: even without data, my signal drops on and off. What could be the problem?
