Sms not received and sent anymore, bad call sound quality - HD2 General

Well...that's my problem...
I can't receive or send SMS anymore...
Last SMS I received did not make a sound or a reminder...I accidently clicked on sms tab when I saw it...
Last few had some problems with new messages notification...it just did not disappear for a lot more seconds as it should...
The second problem is incall sound quality...
I hear very bad and sometimes computer voice...
The person on the other end hear echo of his voice...
I had this echo problem for few weeks but it was very minor...
Now suddenly I can't use SMS and calling is so annoying...
And I am very sure these problems are connected because they started at the same time...
Top taskpar also does not bring up notifications menu...only start button works and battery bar is updated...
What could be the problem?
Software or hardware?
I am using EnergyRom, but never had problems with it...

I'm guessing a problem with Radio, due to the sms failure and robot voice in call. Try flashing another RADIO, it might solve the problem.
Sent from my HD2 HyperDroidCM7v3.1 using XDA Premium

I've been using radio and rom I have for more than 3 months...situation began 3 weeks ago...
If I flash the radio again...do I need to hard reset?

Hard reset may be a good idea & you can make a backup first thus can recover fully if reset does not resolve issue.
Are you sure sim card & network are free from errors ? have you tested sim in another device & another sim in your device ?
Does the signal strength apear in normal strengh parameters.
What network/country is this happening on ?

I guess I will reflash radio and new July4 rom because I use June1 rom...
I am in Slovenia, I use Mobitel network...I did not test SIM...Signal looks same as always...
I did remember something new...weather location says Slovenia and not city anymore...this has been since the problems began...and it doesn't update weather very often anymore...
Internet connection works well...
Probably flashing would be best option...if it doesn't fix the problem, I'll return the device to be rapaired...

Sounds more like a network change & perhaps your device phone band settings & sms centre number need adjusting ! weather failing to update &/or not pull actual location is normally always network tower related so I guess Mobitel may have done some reconfigering of its towers !
Really worth swapping sims & another device before flashing or sending into repair. Also a call to Mobitel may shed some light on any network changes if you get a brighter than average human call centre drone ...

Signal problem in PDA2K..

hey guys...this is my first post here...
my pda2k keeps on dropping signals and sometimes halt during a call...
at first.....as instructed..2 time restarting solved the problem..
can you guys plzz help me out.......im using wm6
thnx in advance
What version of Radio do you using ? Try to upgrade to the last version.
my BA info is as follows
ROM version 5.60.00 WWE
radio version 1.12.00
well from where can i get the latest version of radio??
wel..i found it..and i am upgrading radio...
less see what happens
.....upgraded to 1.15.00
....no success......
im not the first one to have this problem..it ws in 2003. 2005 and now in wm 2006 now....
dunno what to do.....dont wanna throw away my pda2k
Maybe it is an hardware problem?
If your problem is in WM2003, WM5 and WM6, just get the phone to a repair or a recycle center....
but the thing is ..it was working fine....
and after installing a resh rom...it works for like 2 days with no problem...
im sure that its not hardware issue....
its the same problem....which everyone esle is having in this forum..abt signal dropping...dun think tat this harware problem can come to lot ov ppl at the same time...
the problem is with the phone company...
my pda2k also gives me similar problems...
but when i'm travelling to some other countries and using a local sim card there... i do not see any such problem... even while roaming sometimes... i do not see any problem with the current sim card.
i think it is the home service provider which has the problem.
If you have signal dropping, replace the flex cable.
The flex cable signal dropping is a common problem to any slide phone.
In fact I slide the phone halfway to test the signal if it will drop or not.
No signal drop means good flex cable.
Same case with Nokias and other phones.
I've had my friend's BA flex cable replaced and signal drop is solved.
also, one old battery can do that issue.
with my older battery, it used to cut connections sometimes. with the new one, keep connection.
hmm...but the thing is...that this fone was working fine in my country i.e Pakistan..but its giving problem here in canada.......and it actually came from canada before....
i dont know what to do....there were also issues like that with my imate-Pocket pc before...and now same is with PDA2k...
i have chaged a lot of sims...but no success.......
I personally believe that there is a bug on the radio dll.
If you are using WM2003, try this workaround to see if it helps: http://forum.xda-developers.com/showthread.php?t=340557
In your case, activate only the 1.900Mhz band or the 850 / 1900 band only. I believe that the former is better, though.
I've been only using it for the last 2 days, but so far so good.

Well same problem here in Bulgaria. We have 3 Telecoms. Unfortunately i have subscription to one of them and some times like every couple of months I have the same problem. Green light blinking, but when someone is calling me - out of service. It rings, but after i pick up - it drops the call and gives "No service" This last for about a day or so. When i switch sim cards to another service provider - it works fine. The same thing happens when I travel from one town to another. I thing this is due to poor software configuration in the GSM towers. Overall for three years this happens to me like 10-15 times for couple of hours to one day. And I have this problem only with one provider only. No work around as far as i know.. Sorry
signal problem partially solved.

Guys,
Definitely the problem is software. I'm from Brazil and my operator is TIM. I tried many ROMs (at least 10) with the same symptom: if the phone misses the signal, I get into troubles to find the signal again and it keeps finding another operator instead TIM (in my case it only finds Vivo - which is 850Mhz).
After those many trials, I found a ROM that solves the problem partially. It's the PV DVH 19701 ( http://forum.xda-developers.com/showthread.php?t=390008&highlight=19701 )
With this ROM, it still looses the signal when on a place where the signal is not present and don't find while returning to a place which the signal is present, BUT, I just tap the antenna on the top of the screen, tap settings > network and finally tap "find network" and VOILA, the signal is back without much pain!!
One more thing is a little change on the registry according to a recommendation from Microsoft. Using one registry editor, go to:
HKCU\ControlPanel\Phone and change the value for "Features" parameter from 204c7d8 to 206c7d8. Remember that before you change, you need to choose the view mode to hexadecimal.
That's it folks...have fun!

call receiving from time to time

My dual is strangely working from almost a week now. He didn't receive any call during a few minutes and then receive the sms from Orange telling i've missed some call. Form time to time I also can't phone or suddenly can phone again. Half an hour with Orange support when we try almost all that's possible on line dut that didn't help, and that's wronger and wronger alllong the day.
So It's now send by Orange to HTC and I'm waiting.
Did you heard somethings like that? Is it a Dual Known problem? or an Orange room problem?
Any answer welcome....
The Icon on the top said that the reception is good (three vertical lines)
and the sim card work well on other phone (tested on a Nokia and a Touch)
New HTC Dual received today.
The new one's working well untill I add some softwares.
The Niki again began to receiving call from time to time, call from the Nki still working.
The problem began after updating Norton security and adding s2u2.
Didn't really know which one is causing the problem, both are working well on a touch.
The only difference between my Touch and my dual is that the dual had am Orange room. Did you have information about that?
More trying.....
After a week of working, today, the problem of call receiving began again and is worse and worse along the day finishing with no call receiving and no calling from the niki possible. It didn't recognise any provider (at the beginning of the day, it find Orange and I can phone but not receive any call, all are going to my voice box.
I hard reset again the Niki, and install my last working backup with no more result than a non working phone but only a pda.
Carefully installing again quite all my software after a hard reset and the phone is working now perfectly.
The only think I found different from the last try is the small pop up who open when clicking on the icons on the top (connection, sound...). The pop up has desappear when the Niki's not working. The problem is that I didn't know which software is causing the problem.....
Any idea?
The problem is also only at work..... So may be, something in the surounding seems to have an effect on the Dual reception. Strange as Iphones, Touchs or Nokias seems to have no reception problem in the same room.
Ive also have the same problem, but ive solved it by disabling 3G and just going with GSM on "band" selection.
Can you see your network signal bar having one line only then this is the solution for you. Just activate 3G on sites with good signal.
Thanks for the advice, will try.
As my working place is near some IRM machines (working in an Hospital), Is it possible than my problem arise when all machine are working at the same time?
As the hospital is big, I think than almost one is working when I'm at work, but as the problem arise from time to time, not regulary, it look like something affect the NIKI reception and perhaps only the 3G. To confirm that, I left from time to time the connection when I walk just along the place where all IRM machines are.
Anybody can confirm that?

The signal is almost very good even when calling and receiving calls is not possible.
So, it seems that magnetic fields created by IRM machines can affect 3G+.
If the problem is due for example by the size of the walls, then 3G+ will never work at this place nor the GSM.
Just talk yesterday with an Orange Tech.
The UMTS antennas in the surrounding are at the same place than the GSM antennas, so my office had the best theorical coverage possible in the town.
The UMTS waves be affected by electromagnetic devices in the surrounding explaining why call can from time to time be directly rejected to the answering machine even the connection icon on my Nike is always with three lines and didn't change. It explain also that, when the phone card is inserted in other phone without UMTS, it works without any problem.
So thank again to muzikfreakah for giving me the solution. However UMTS seems to be not a very useful add.....
Is there any utility to switch automaticaly from an auto search to a maual search on a time base? Will be useful for me.
Hi i had the same problem, and found that it was the new S2U2(Newer then 0.98), that messed it up.
Im using 0.98 at the moment, and it works fine.
Anything newer than 0.98, hangs any incomming calls.
The one calling can often hear up to 10 rings, and my phone rings half a tone, when the caller hangsup, so theres no time to answer the call.
Thanks for your advice muuu, but in my case, the problem appear only from time to time at my office. So the theory involving electromagnetic fog seems the best. UMTS work fine when I'm outside work or at home and never miss a call.
However, when at work, I'm only sure with GSM to receive or make call. Seems to depend of the use of IRM (just near one of the bigest IRM machines concentration in Europe with some still under development).
S2U2 is working perfectly even with the latest version if I respect the no 3G at work and switch it back when not working.
Hope this may help somebody in the futur
Thanks I had the same problem so removed S2U2.
After talking with IRM experts, it seems that I'm rigth..... IRM interfer with 3G and Wifi and not with GSM
Switching to diamond a few month ago and never had such problem with the diamond!
Nike seems to be the only phone affected and mine after stop working during holiday's was changed by Orange for the second time. Seems to work well now for my wife, I've not tried again at work.

HD2 no signal, shows exclamation

Hi everyone, my HD2 just stopped working with no signal at all.and shows a exclamation all the time, sim cards are no problem. i've updated the phone with official sw, still have this problem at the beginning.
has the phone been blacklisted?
is the phone turned on in wireless mode in settings? ( ya never no)
is it still under warranty?
My HD2 has done the exact same thing, just shows an !
it doesnt even try to find a signal.
phone was a tmobile UK version, which was unlocked to use any network.
the problem has literly just happened today.
have tried different offical roms, and different sim cards.

Just phoned my provider in regards to my phone, quoted the emei and have been told the phone is blacklisted.
they are sending a request to have it unbarred. will post the outcome.
I have had this happen alot with Vodaphone UK. This is a brand new number so doubt it has been black listed.
I can get this working my turning the phone to airplane mode then back to phone mode, this most of the time makes the phone look for a signal.
Usually happens to me when there is no signal like in a tunnel, the phone does not seem to try looking for the network until you force it to.
This is possibly a fault with the timeout of the HTC HD2. Could be once it tries to connect when out of signal the device gives up after a number of attemtps.
Does anyone know?t

I was searching before posting for just this problem.
It is really irritating me. The phone can jump from deciding there is no signal to sometimes even going to full-bar "H"!
I hav currently resorted to turning off 3G as at least that way I am eliminating the idiocy of it prefering 0/1 bar of "H" vs near full non-3G reception for calls.
Even so at times it will just sit there for ages having dropped a signal with the exclamation showing and then jump back to life [in the same place] with good reception.
I am also on Voda UK
Mine has done that twice, in 4 months. 1 time phone was turned off inside connections, no idea how? 2nd time I just shut off, & back on, signal was back, hasn't happened in months now?
so does anyone have a solution to this problem?
I've checked with my service provider and my phone is not blacklisted...
My SIM card seems fine and everything else seems fine, except it keeps giving me the exclamation mark.. most of the time i notice it's when i get out of the lift (but that could be because that's when i usually check my phone before I put it on my desk).
There are many occasions (probably 5+ times/day) where I turn my phone on (ie, off standby) after it's been sitting on my desk for an hour or so to check calls, etc and there is that dreaded exclamation mark.
I know the area around my desk does have a signal because the guy next to me on the same network has a strong 3G and 2G signal.
Sometimes going to Comms to turn airplane mode on and off to force it to look for a signal works, but sometimes it doesnt.
I've tried soft-resetting, hard-resetting, using different radios, different ROMs, etc and still no good.
Funny thing is, it's only been happening over the past 2-3 weeks.. and I'm not sure what triggered it.
It's really starting to frustrate the crap outta me and friends have been asking why they can't get through...
Any help would be appreciated.. . I'm trying to avoid sending it to the HTC service centre if I can because they're slooooow and the stories I've read about my local centre are pretty bad (when I had my HTC diamond).
Solved:upgrade your rom everything gonna b in place
Upgrade to what?
I am having the same problem, for a hile now. Been fiddling with phone settings parameters, trying to see the effect. One particular combination so far seems to work. Try this: Comm manager --> Phone --> Tap Change Phone settings --> Menu --> Advanced network --> GPRS --> select CHAP authentication --> then CSD Line Type --> select Data rate 9600(v.110). Then OK, Back, and Done with the Comm manager. Observe if the network pickup performance (switching from non-existent H or 3G to E or G) works better for you after that. It does better for me, so far.
I'm having the same problem - NO SIGNAL
Any solution?
i recently discovered that for my problem, it was to do with the earphones. Not sure why, but it only seems to happen to me not long after i plug or unplug the earphones.
I usually have my HD2 on my desk with the music going while I work, but every hour or so, I unplug the earphones and take my phone by itself out with me for a cigarette.. then I come back and plug the earphones back in.
Often when I'm about to head downstairs, I turn on the screen while the music is still going and i see the "!"... as soon as I unplug the earphones, the bars indicating reception comes back straightaway!
Not sure if it's a coincidence or whether it really does have something to do with the earphone/earphone jack.

I have just bitten the bullet and accepted the phone is crap at swithing between 2G and 3G signal so turn off 3G in a couple of locations when I know I get this problem [home - I can use WIFI] and my office.
HTC would not be drawn at all on un updated Radio and this problem being "fixed" in USA ROMs
Fixed
the very easy fix is to do this :
settings _ personal _ phone _ network then make network selection to manual ,, then choose ur provider,,, then u will have signal,, after that u can turn it back to automatic
100% working
Thanks a "fix" not a solution.
Rather silly to have to jump through hoops to make a mobile phone recognise available reception
Have the same problem
I have the same problem now, any solution for that?

Gsm signal issue

I have my sgs for 2 weeks now. GSM disconnects around every 2 days.
At service mode (*#*#4636#*#* - Phone information) i can see this repport:
GSM disconnects:
====DATA=====
State: inactive
disconnected with last try
at 00:59
fail because No Error
The question is: why does this happen?
Is this an android issue or a hardware problem?
Any pointers?
Thanks in advance

do you ever enter a building, subway, or some other location where the GSM becomes poor?

That's not the problem.
Gsm disconnects just like that ,at home for instance. And when I notice that and try to reconnect (settings- wireless networks- mobile networks - networks operators) it doesnt find ANY of them.
Then I restart the phone and gsm network is back.
If I dont notice disconnection in time (so I can restart phone, people just cannot reach me....quite frustrating...
i see what you mean now.
yes, i've noticed that on mine too, but.... that's because i was fooling around with some new Apps Widgets settings i was testing to control the radio and data to save battery.
Did you install any new Apps recently that might cause that?

Well I installed all kind of apps. but i have the feeling this problem was happening even before that.
And I dont need widgets to control data ( I think) because I set the sgs to use 2g networks only and I dont have apn configured( section is empty. Internet connec. only via wifi.

Well, my sim card is VERY old (2002) and the carrier (Telfort) is roaming into another carrier's network (Kpn) with no extra costs of course like real roaming, but still roaming (I get the little "R" next to the signal strenght bars)
Anyway this never happened with the Nokia 5800xm running Symbian OS and using the same sim card...
Starting to get pissed of with Android...
With Symbian you hack or root or tweak because you want to, not because you NEED to like with Android....
And then you prob. get side effects...
Thank you guys for your time
I would get a new sim card if I were you. Every android phone that I have had seems to work better with a good 3g sim.
Get a new SIM card.
same problem, different phone
i have the same problem on kaiser with flashed android on it.
sim is 2 years old, and now suddenly this happened, tried differents sim cards, but the problem persists. My guess is, it is a software problem.
Maybe i will report when I flash original WM6.1 rom onto it, if you are interested in the result
btw, this happened about two days ago and because of this im buying galaxy s so i hope the problem will be gone with new phone

Why you think the problem will be gone if it's still android and I also got it with my sgs? Or are you counting on Froyo?
Yesterday I upgraded my sgs to froyo jpc with kies. I am new with Android but the post of Aery was so clear that i didnt resist: http://forum.xda-developers.com/showthread.php?t=769400&highlight=froyo+upgrade
I did get stuck on reboot but could get out of it after applying a cache/data/factory reset on recovery mode (3 buttons)
Now I am being carefull with the 3rd party apps., and so far so good, no gsm disconnections .
Froyo is of course better that eclair but Android is still disappointing to me.
You flashed Android onto a WM device (i'm impressed); could you not teach me how to flash Symbian onto my SGS?
Voice dialing (over bluetooth or not) and proper connectivity control (network, data, gps and bluetooth) of android is years behind Symbian; and such a well written, light OS, it will just fly on a high-end hardware like the sgs; but that is an issue for another thread.http://forum.xda-developers.com/showthread.php?p=7938430#post7938430

I think indeed that's not the same issue. My problem is that the radio signal get turned off during inactivity. That's why I got connection back after reboot: radio signal gets turned on again; later I learned how to turn radio signal back on without rebooting, but that is just a remedy , no real solution.
Try to upgrade to froyo, make a factory reset and be carefull with 3rd party apps. With froyo you will need less interfering tools anyway
I dont thing that my old sim card is the problem, but i'll try to replace it anyway...but first things first
Btw dou you have 3g turned on? Cause I never...
Another mistery: When I have 3G on I see those bars (signal strenght) dancing and that "death grip" thing happening:http://www.youtube.com/watch?v=LROTHrTR92k
But when I have it on 2G only the bars doesnt move even if I strangle it with both hands.....
Please repport later how it's going...
I had the same issue, i sent mine back and got my money back, i had also tried with different simcards and resets and nothing worked.. so hopefully my new galaxy wont have this problem. Its strange that these problems are so rare though.. But as long i get it going ill be a happy man.
fourth day with JPC ( and 4 days after a factory reset) so far so good no disconnections . I think problem is gone...
Today just to be safe, I got a new sim card....the other one was too old anyway(8 years)
i have the same issue, for a few days i can't get 3g. i'm seriously wondering about sending back my sgs. i've ttried all the settings, changed my sim..nothing...begin to think it was a fullish thing to change Desire to SGS..

Well... this is not the same issue.
I have 3G (WCDMA) disabled. I only use 2G (GSM) and WIFI for data/internet connection.
I Dont have a data account, I dont need it therefore I disabled 3G in order to save battery.
If you do want to use 3G, just go to settings - wireless and network - mobile network settings - network mode and set auto-mode (GSM/WCDMA or 3G/2G)
If it doesn't work, apply a data/factory reset and try again.
And if it doesnt work, it's probably hardware related and you should return it or send it for repair.
My issue is more complicated; next to the fact that I dont want to use 3g, my carrier is roaming to another network and probably Android OS or the firmware cannot handle it properly.
Android is still premature and the "Samsung - Android integration" seems to need a lot of development as well.
It is just a shame that basic functions like proper connectivity control just wont cut it. And Google is not doing any good either.
And dont let me get started on the voice recognition issue......
Hardwarewise, the SGS is superior that htc desire.....I wonder how it would perform if running Symbian^3 OS or Meego.....
I get a great sound quality from the stock music player just by mixing the equalizer and using the music clarity effect...just great...better than any other device I tried.
And the OFFLINE Gps experience is just great as well: the combination SGS - Motonav - External Bluetooth gps device is working like a charm.
I wouldn't change my sgs just yet......
yesterday i was swiching sims to determine if is a sim fault and suddenly i have my 3g/h back. happy owner again. i've tried all to do this, from firmware upgrade to servide mode settings..i don't know why but i'm ok again...

It is just a shame that basic functions like proper connectivity control just wont cut it. And Google is not doing any good either.
And dont let me get started on the voice recognition issue......
Hardwarewise, the SGS is superior that htc desire.....I wonder how it would perform if running Symbian^3 OS or Meego.....
I get a great sound quality from the stock music player just by mixing the equalizer and using the music clarity effect...just great...better than any other device I tried.
And the OFFLINE Gps experience is just great as well: the combination SGS - Motonav - External Bluetooth gps device is working like a charm.
I wouldn't change my sgs just yet......

Hello,
I know its been a long time since you wrote this thread but I just came by it!
I have the exact same problem with you (I had it since August) even now with the official froyo. I tried factory reset and no new apps (that could cause the problem) but it still disconnects randomly in GSM mode. However, when I have it on auto (gsm and wcdma) I have no issues. I just disconnect data from the power button in froyo. I am wondering if you ever found a solution..

Well, I am subscribed to this topic so I saw your post.
Good and bad news:
First the bad one: No solution yet, it keeps disconnecting IF I stay on "gsm only".
And the good (or a little better) news:
I noticed that on sgs, using "gsm only" or "gsm/wcdma (auto mode) makes no difference on battery consumption....
By the way, this is a Samsung issue, not really an Android one.
On a HTC Desire HD, you can use "gsm only" mode with no problems...
Thank you for your answer!
I noticed that about the battery too. So not too bad, I just have to keep it on auto mode then..
Same issue
Im having the same issue but in a optimus t the worst part is that i cant get service at all.. when i press change network preferred it wont change and when i try to press on turn on radio it wont work either....

Phone loses connection!!! Please read!

Hey all, I have a little (or a big) problem. It is so, that my phone sometimes loses connection. Than I can't call, send messages, go on the internet. So now to my question. Does anyone has/had the problem, and is/was able to solve it?
I wouldn't like to give my phone to samsung, because my imei corrupted (I don't have a backup of my /efs folder), I have flashed several times, and I rooted it several times XD and I don't have a backup of my orange fw (I live in Austria).
So please help me (if you can)!
best wishes

WHich version do you have? Is there a specific time when phone loses connection?
I had connection loss problem and that was related to mobile internet. You can try to disable mobile internet and check.
For Original ROM, go to samfirmware.com and download the original ROM, update your phone to orignal ROM and go to samsung service center and tell them about IMEI loss. Just show that you dont know anything
I have lestatious v1.7. I know samfirmware, but there is not a version for orange branded gt i5801^^ but ty for your quick answer^^

sometimes i get disconnected... what i do is go into the plane mode and come back out... connection restored...
It started doing this after i got my mainboard replaced... so could it be hardware related?
It happens with me also sometimes. Going into airplane mode and coming back doesn't help. Restarting doesn't help. Replacing sim doesn't help. Even inserting another sim doesn't help. Only fix I have found is walking over to a different area physically. Atleast about a kilometer or so and it latches on to the signal.
