[Q] Signal problems at my DHD

Hello guys,
I need some help here with my DHD. My serious problem is about its signal. I am in my home and i am talking on my DHD, but sometimes it loses the signal. In my house, the signal is very good, not always at 3G but at 2G it is always at full signal.. Although, it sometimes loses its signal and my call is closing.. By the way, to be more clear, when my call is closing i check the signal, and i see it to be full... At this step, when i am checking about the signal, sometimes i see the signal to drop down to zero, after 1-2sec.. But the other times it stays full.. But in both of these cases, my call is closing many times.. What can i do to solve this problem, anyone knows?
Thanks, and i hope to help me with this.
P.S. Sorry for my bad english guys And one more problem that i have is that my DHD few times, it lags, stucks, dont know how to say it, and in first case it unstucks afters 30-40 sec, or in second case it restarts..

AFAIK, the gsm antenna is located in the bottom cover that the sim and microsd is hidden behind. If the contacts inside dont make a good connection you will probably get lost reception from time to time. You could try another cover, or bend the two gold coated spring contacts near the simcard very slightly outwards to make the connection more reliable.

I tryed it mate, and tnx for your reply. But today in the morning, when i was talking on the phone, my call closed 4-5 times in a 20min call.. Dont know what is happening, but maybe anyone of you guys knows another tip to help me? Maybe any change on the software? And by the way, my phone had in automatic the choice about 2G/3G, but i changed it some days ago only to 2G because in my house the 3G signal is not so good always, and if it loses the 3G signal and it needs to change to 2G, the call is closing for sure..

I have the same problem with my DHD, I live in an area where the 3G signal is crap. I found that when running CM7 you can switch off the 3G and just use the 2G which helps. If you using a sense ROM you don't get that option which is a pain, so I'm sticking with CM7 for the time being until someone produces a workaround for the other ROM's.

You can swith off the 3g in Sense ROMs, press Menu > Settings > Wireless & Networks > Mobile Networks > Network Mode change to GSM Only not GSM/WDMA Auto (WCMDA is 3g)

Try your sim in another phone. If the signal is still bad you should try contacting your network operator and ask them if there are any faults or if they can do anything to improve your signal.

No sense is like CM7 (Cyanogen Mod 7). They are as close to standard google android with added features. Standrard android is found on googles own devices like Nexus and Nexus S. Although CM7 is based on AOSP (google it). Sense has a different (rosie) launcher and added extras included such as widgets, Icons, and other extra HTC only features. Look in the Desire HD andorid development thread for different ROMS with sense no sense.

I was using some times another phone but i didnt have this problem same as i have it on my DHD. Yeah, maybe i had it few times on my other phone but occasionally, and not so many times like these on my DHD.

I had the same problem. I had to order a new sim because my sim card was old and apparently wasnt very compatible with my DHD. I'd suggest getting a new sim from your service provider
Hmm leaked from my thumbs through my mobile device....

When u are saying that your sim card was old, how many years do u mean?
Cause i think that i have bought it about 4years ago... You think i have to ask for a new sim card with the same number or what??

[Q] 2.4 update broke 3g

I flashed 2.3.4 onto my 2.3.3 R800i and now I can no longer get 3g to work for anything other than messaging and phone calls. I've tried everything i could think of in the settings, any clue how I could fix this?

Did you put your apn settings in?
Sent from my R800a using XDA App

I had a problem with 3G long time ago after being abroad and using Airplane mode and/or data settings. Could not reactivate 3G for some reason and rebooting did not help but I had some on/off widget thing installed at the time and tried one of the 3G or data switches on it and it started working. Hope it helps

Sent from my R800a using XDA App

mine has a glitch where it switches the network it's assigned to by itself. Rogers shows up as two networks, one edge and one 3g/hspa, and I noticed if my reception is bad at a certain location it will sometimes switch to edge only, and not turn back. It's only been doing this after the update to 2.3.4
Edit/update: I figured out you can force the phone to never use edge, if you change it from wcdma preferred/gsm to only wcdma

[Q] data lost while on call

when i am on a call i cant not see to get data...the data connection turns off by itself and when the call ends data connection will come back on? is it suppose to be like that or is there something wrong with the phone. right now im on software 1.28.708.10. thanks

Happens to me too I believe my frined.
It only happens with mobile data though.
If you are on Wifi, the wifi should NOT disconnect right?

ya if it is on wifi then it is ok. not data connection though

I believe that the phone switches to 2g during calls, and not sure whether this is a telco setting that they do not allow calls through 3g, or a software feature of the phone with the reasoning that 2g signals are generally stronger in most parts of the world compared to 3g.

Just fyi i had the same issue on my "old" Desire HD.

It might be carrier specific. I have no trouble getting (and keeping) HSPA data when I'm in a call.

which version do u have Barry? I am using the international version on rogers. Are you using the at&t version?

Then I believe it to be carrier specific then since the software governing these kinda things should be standard across the board

ok so i dont think its the carrier cuz i reset the phone and it works sometimes now. if i make a call and browse right away then it will work but if i leave it for too long then it wont work.

guys its because the phone calls you make are on a 2g bandwidth unless its a video call, that's why if you have 2g connection or EDGE active it will get disabled as soon as you make a call.
to clarify, force your network settings to wcdma and then connect to 3g, after that make a call and your 3g will not be disconnected

Hi Marktang... I saw your post from Google as I lost data connection during phone call with my Galaxy S2.
May I know is it after configure the Network Mode inside the setting to use WCDMA only, then the problem will be solved?

Odd data problem

Ok so I have an unlocked LG Nitro HD with custom ROM (CM10) and it has a very weird problem. I've tried two different AT&T MVNO SIM cards (AirVoice and Consumer Cellular) both have the same issue. My data signal keeps changing from H to H+ and occasionally to 3G like every few seconds regardless of where I am using the phone even outside. I don't understand what the problem is. What could be the issue?

Data does work but it seems to drain the battery with the networks constantly switching and on occasion I get a "No Connection" screen on certain apps, I guess because if I open an app while its swapping networks the app cant connect. It's strange.

They are set up properly.
I had another odd problem, just a few minutes ago was texting someone and all of a sudden phone froze while vibrating then restarted! Don't know if that's a bug in CM10 or what, maybe the network swapping is as well.

Maybe make a backup of your CM10 and try flashing a different ROM not based on CM10.

I think this is the same issue that I recently fixed in quattrimus. I will try to get the fix included in the cm kernel soon. You might try my Rom to see if the fix works.

I tried installing CM9 and it appears to have fixed the problem, the phone doesn't try to connect to the H+ network anymore, only the H network and seems to stay on it so far. I did see it quickly go over to the 3G network but it doesn't appear to be causing any issues, it went right back to the H network. However, I really wish the CM10 ROM worked right, as CM9 is so old...

CM10 is snappy and oh so buttery smooth, I give you that. On another note, did you try any other CM10 variants? I'd give tdmcode's AOKP a spin. He says he might have fixed that problem you were talking about in his build.

I downloaded the CM10 ROM. It seems to behave slightly differently. It stays on H normally, but when I start to do something with data, it will go to H+ until the data loads, then go back to H. So far no disconnects, I'll keep you posted. Right now I have very limited data, I'm switching to T-Mobile as soon as UPS decides to deliver my SIM card (just found out they have a 1900MHz HSPA+ network in my area!) I'll be able to test it better then, but for now I'm trying to stick to wifi, especially since I wasted so much data tonight playing around with this stuff, lol.

Ditto... H and 3g are subsets of each other. Namely they can handle simultaneous voice and data 4G (h+) and lte can only handle data. So it switches back to H so you can receive and make calls plus it uses less battery. If you are on either 4G techs and receive a phone call while downloading it will automatically switch to H from h+ or lte, this is why. The only way you will never see this is on an AT&T rom where it only has 4G and lte icons.

H+ isn't a subset of 4G is it? I know that the CM's have separate icons for 3G/H, H+, 4G, and LTE.

That certainly is debatable but the US's largest carrier considers it to be, it behaves like 4g, H+ may not be as fast but it is 90%+ as fast in most markets small enough to not make a noticeable difference as far as people's perception and the technology behaves like LTE in a lot of respects, CM is international so it just conforms to International norms so that's why you get H+ AND 4G (LTE) designators.

Fixed service dropping and locked LTE

I finally got LTE locked on with Telus other users confirmed Rogers, AT&T and Bell(thanks) . No service disconnections, even while on wifi.
The problem I see is conflicting settings while flashing roms/modems. This seems to be the only fix. I'm pretty stoked I figured this out because I was about to switch back to my s2x out of frustration.
This took a lot of trial and error, literally had nothing to go on and no where in particular to start. Enjoy.
MAKE SURE YOU ENABLE LTE TOGGLE IN ROM AND HAVE IT ON BEFORE STARTING.
1. Network mode(settings/wireless & networks, more/ mobile networks/ network mode) set to gsm/lte/wcdma
2.Phone setting in test mode *#*#4636#*#* set to lte/gsm
at&t / rogers should select gsm/lte/cdma in test mode
3.Recovery flash latest modem mumLL1
(at&t users flash ucdlk3)
Wipe cache/dalvik
4 . Reset. Give it a couple mins to ask the network for lte.
If you disable Lte(through toggle) and want to use 3g/H+ for battery saving, the only way I've been able to reconnect to it; is to re enable(toggle) and reset, wait a couple mins to connect.
Side note: depending on your 4g service area, it may bounce around 3g/H+ which is normal.
When you place a call it will drop to 3g (the believed reason for this is that the phone knows you won't need heavy data so falls back to ease up on the battery during calls) but will reconnect a couple mins later. Our phones are slow to negotiate Lte connections with the radio testing sockets and network stability before committing, so be patient.
Let me know if this works for you and which network. Thanks.

Yes everything works. I can unselect lte in my toggles and it drops to 3g/hspa. When I re-enabled lte I noticed that I have to make sure in network settings lte/gsm/wdcma is selected and reset phone.

Which rom are you on? Should be up in your toggles. Basically it changes you network settings from cdma/gsm to lte/gsm/cdma. But it conflicts sometimes.

Its there it just doesn't do anything because all the modems on the Att S3 are Rill locked or something so we don't have the option to do it so easily

So let me get this right. This fixes the signal jumping around on cm10/aokp ROMs?? That's the only reason I stay on a stock based rom. I'm tired of seeing my signal jump back and fourth from 4g to 3g etc. On stock I always have a rock solid signal. It does not jump around..... Thanks in advance...

stock lies to and shows 4G all the time, cm10 and show the truth. the s3 sets at 3g until data is needed then transfers to 4g
