Exec looses signal

Hi guys,
ive had my exec for about 2 weeks now. In the last week it has started to randomly loose network signal. It keeps searching till you either soft reset it or turn flight mode on and off. It will find a signal in about 10 seconds after that.
Is this there a 'dont keep loosing signal' setting that im missing?!

Mine does the same thing - annoying as hell! Not worked it out yet.

Are you talking about telephone or GPRS signal ( U or G )

Phone signal

everything! it looses all signal.
I called o2 and they want me to go into an 02 shop for them to have a look at it before they give me a replacement
The are all 'handset trained' apparently.

I also called o2 a week ago stating the same problem, They gave me a refferance number and said they will look into it, But of corse 1 week later they have not called me, So this afternoon i will find the referance number and give them a call.
I will post ther Bollox answer on here tonight

Same problem here with a MDA Pro. I ahve noticed that this happens when I am roaming in Germany as well. Very anoying. That and the thing freezing in a call and needing a re-set. This is my second one as the first one the screen portion became loose, happened on the one before as well.

I have the same problem althoughmine will refind the signal after about a minute. It seems to disappear whenever I ask thephoneto do something new (open a program etc).
I finally persauded T-Mobile to exchange mine so I'm getting a new one delivered tomorrow.
I'll let you know if that fixes it!

My XDA2 used to lose its ability to communicate if I was out of a signal area for more than 15 minutes, but I haven't had it happen yet with the Exec. A soft reset or Flight Mode on/off cycle would fix it.
It is frustrating but didn't happen often.

Well i phoned o2 and they said there was still no answer and that no one else had complainded about this, So i told them of this forum......
As per the last post i have also had this on a 2 and 2i, and i gree if its out of servie for a few mins its seems to give up looking for service until you reset.
mine has done it overnight befor, i looked befor going to bed and it had just the 3 dots flashing where the aerial should be. the next morning it was still the same, quick soft rest and into full service, thats when i first rang o2
John

I've had this on all my XDAs in the past, and seems to continue with the Exec.
Very annoying, but not sure what can be done about it.

guys,
wait for a rom upgrade from o2, ( with new radio rom)
that should solve the problem.
happens with xda, xda2, skipped xda2-i and xda2-s,
and now it's back.. :roll:

Hi Guys, I have been having this problem for weeks with my MDA Pro. I convinced myself it wasn't the phone and that it was T-Mobiles Network. In desperation last night I spoke to T-Mobile about the problem. They told me it was a faulty phone and that I would have to contact the supplier of the phone and ask them to replace it. I tried to explain others had the problem and that I wasn't happy to have to send my phone off and wait for a replacement. But no avail. So I sat down at home and looked at the settings. I think I might of cured it! Maybe it is a fluke but by clicking the signal meter and going to settings, then changing network selection to manual it has stopped hunting when it loses signal and quickly re-picks it up. HNope this helps others.

Defenitely...that did it.
I had the same in Holland with KPN: while switched to manual no more problems.
In Romania however, where I also have UMTS, I had to switch it back (or it switched itselve back, after changing SIM card, I don't remember) to AUTO.
There it switches from GPRS to UMTS if UMTS signal is OK.
Huib

Ok, i have the same problem. Have GPRS Always on set in registry and 10 minutes ago, my MDA Pro lost GPRS connection. It trys to reconnect all the time. But no Connection can be build up. After Flight Mode and back, i get a connection immediately. But on start of MSN Messenger, it loses the connection again and does the same loop like before. Only a softreset brings my connection back to live.
Looks like a ROM issue. Maybe GSM or CE.

I am delighted to say that my replacement MDA Pro seems much more stable in the signal department. Although I still loose signal ocaasionally, I no beleive that is due to poor signal area and not the phone...
If you phone isloosing and reconnecting all the time then like mine it is probably faulty! Hopefully the ROM upgrades will sort out the last few issues I'm having!!
I love this phone!!

Same problem with JASJAR
People still have this problem? i'm using radio 1.03.01. When i used the original firmware, the phone part would lock up (Would get the busy - wait 15 seconds and try again, but it would never clear - had to soft reset)
With the 1.03.01 radio, i still get disconnected, but it'll find the signal again after a few retries - which is very bad! I rely on the phone at work, and people can't get through when it's disconnected. I have full signal strength (4 bars) so it's a software/hardware problem.
It looks like maybe it happens more frequently when charging or activesync'ing, than when it's disconnected from usb.
Can anyone confirm having the same problem, and it getting better or FIXED with the new radio firmware? If not, i'm going to have to return it.
Michael

I am using radio version 1.04.02 on the O2 exec, although i use a Vodafone SIM (supplied by work!). Mine suffers from the same problem, mainly at home, which is a very odd signal area for Vodafone. I can go from no signal to full signal to none again, and yes, sometimes it drops completely and needs a soft reset - bingo! full signal again.
Switching the network type from auto to GSM does seem to make the unit a little happier, but i need to use WCDMA when possible, so i leave mine on auto and live with the dropouts!
Lets hope the next rom fixes the problem.
Cheers
Paul

I have the same problem with my XDA and O2. a soft reset nor a full reset have been able to fix the problem. :roll: is the new rom version available as yet?

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.

Since I upgraded to the Vodafone rom on the htc website I have not had this problem

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?

Signal is vary bad

About few weeks ago my Htc Tattoo signal become to be very bad or sometimes full gone. Tried to flash different ROMs, insert different SIM cards, but nothing changes, signal is bad too. When i bought the phone, signal was perfect, becouse I live in a center of the city. So, please, maybe anyone know what the hell is wrong with my phone?

I heard, that it is possibility to reinstall something radio rom. Said, that can fix the problem, but where should i find it?

I have the same problem here. At the time i use the original HTC ROM my phone was connected with 3G and/or HSDPA, but now with fyodor i have the problem that the best connection is 3G.
I don't know how to solve the problem - maybe it is only a display error...?
Is there a application with wich i can test (or see - that is better) how the phone is connecten (GPRS, 3G, HSDPA...)?
kind regards
srkonus

Please, I really need your help. If I took the phone to the guarantee service, they just reinstall roms or something, and nothing changes. I tried to download one radio rom from there http://developer.htc.com/google-io-device.html#s4 but when I am trying to flash it, the error appears and says, flashing aborted. I am using Amon RA racovery if that means something. So, maybe now you can help me?

Try to change your network only to GSM instead of GSM/WCDMA.

I tried that... I tried every option, which is associated with connection.

I have the same problem...

Htc Tattoo is a very very bad phone...

Yea, I've seen this. After a week about, when I return from the trip, I will took my phone to service. They wrote me that, if it is held more than a month, phone should be replaced with the new one.

I brought Tattoo as a birthday gift for my gf,now it bacome the excuse of being late when we date......because she said she can not call me on time. and I never help her solved the problem.(both of us major is telecommunication in the university,what a joke.)
anyway I read the above and other topics.
and try to
1 turn to 'only gsm',
2 manully select oprator, there appears two local oprators, but no radio button on the UI, I'm not sure if it means selected. (do this at where signal is strong)
3 I try to turn on/off 'fly mode' at somewhere no signal.
4 flash other later roms.
no use at all.
on my table signal none. at the window signal full.
but it just 2m between.
my new wildfire and O2 mda is OK on the table, 80% signal.
I like HTC,I just don't sell it as 2ed hand,(half price now......)
I heard flash the Radio can make it better or solved, any one know the details?

Network and GPS Functionality Vanished

Hi all,
I flashed my phone, and thought I’d go with Darky's Raw Steel Edition (4.1), which is awesome btw. I installed it correctly, installing I9000XWJM8 first (the MODEM and PDA, not CSC as none seemed to come in the package).
Everything was working smoothly until I realise 3G/Data Network is no longer working (it did previously). Not only that but it seems it won’t connect to my service provider (Three) at all (emergency calls only), and I’ve also now noticed GPS doesn’t seem to work at all, I can’t even get into GPS test mode. Wireless does however work though it being off, or on, has no impact.
I’ve tried:
Flashing different firmware - Stock JM8 and Doc Froyo’s latest JPO.
Hard Reset
Deleting and re-entering APN settings, though they were correct and already on the phone anyway.
Testing my SIM on another phone – signal is strong, inc. 3G on that.​
I’m really at a loss here. Any ideas anyone?
Thanks
UPDATE: So, I won't bump this myself, but incase anyone finds this thread in the future: the gprs, gps, 3g, etc all work - just not in my house, on the SGS, anymore. I have no idea why - my other phone, it's fine.. and it used to be fine with this phone too. I'll update again if I figure it out.

the other phone works fine with the same sim you are using in the SGS?

Yep, the same SIM works in my old Nokia 6600 fold, people in my house also with Three are getting solid reception right now. 4-5 bars with 3g established.
It worked beautifully all the way home from work on the bus, just not in/around my house.
It's as if the local cell towers near my house have blocked my SGS specifically (can't receive calls or texts either). I did turn the wireless on and off in short succession (which would cause the gprs/3g to try to re-establish each time).. maybe I flooded them and they blocked my IMEI? Or is that just a ridiculous idea?
The real odd thing is GPS not working either (again, just around my house/street); surely it doesn't need a cell site for that?
It does seem as if I can't download apps from The Market anymore either, and have tried various cache clearing solutions to fix it (problem occurred roughly when I noticed my reception was nill).

You might have a problem with the band selection thing of your phone.. have you tried downloading/speed test when you /do/ get a connection? If it seems capped at 40kbps, you might have the same problem I experienced before, of being stuck on 2g. (Despite settings saying otherwise).
I fixed it by doing the solution to having a missing 850 band, the thread of which is found somewhere in this forum.

Thanks. That sort of worked earlier.
It made a slow data connection, and some texts came through.
I then went out to a location a few miles away, had a look and it was still on a slow connection type for a few mins, then all of a sudden it went to HSPDA (with the occasional 3G flicker) and was blistering fast.
Now that I'm back home, I've lost all reception again and can't make/take calls
[EDIT] Clicking around my phone in the hopes of finding something: checked product code in my nv_data.bin file with SGS Toolbox, and it's showing I9000HKDKOR; whilst the backup is showing I9000HKDH3G - could I be on to something? I backed up my efs folder after rooting before doing anything else - so, going to try restoring that.

I have a hunch based on a 2 year old post (http://forum.xda-developers.com/showthread.php?t=445913).
From what I understand, Three UK piggy back on Orange's network when Three's 3G cell towers are out of reach. Orange don't provide Three users with the full service though, just 2G and I'm guessing they prioritise Orange customer traffic.
I think when I flashed my phone, I removed code commanding the phone to prefer Three cell towers. Without that code, the phone simply goes to the strongest/first signal it detects. I'm guessing in the area near where I live, it's Orange (or maybe any old network which is why I'm often getting Emergency Calls only).
This is all guesswork. I'm hopeful, seeing as if I quickly switch the SIM to my two+ year old phone, then I quickly get 5 bars and 3G.. unless the SGS's signal issues really are *that* bad.

http://forum.xda-developers.com/showthread.php?t=831022
Try see if you have the symptom of a missing band?

Hi Nwsk, I tried that before and assumed it didn't work, but actually the change isn't sticking. Which seems to be the case for a couple of others! Thanks for pointing me back to it!
[Edit]
Ohhhh dear. Now I have another theory (I really hope I'm wrong).
I've just read on a thread that some phones don't have the 850 Band, it's down to a lack of hardware support. I'd wager every Three UK branded phone sold will have the correct hardware as stock. I sent my phone back to Samsung for repair, they said they replaced the motherboard.. inference: they replaced it with one without the WCDMA 850 support.

Hmm, I'm definitely no authority on this, since I'm just guessing.. but I figure if that if was a true hardware defect, you wouldn't even be able to get it temporarily?
Are you using any 'battery-saving' type apps? Something might be messing up and keep reverting the settings. I had this occur to me a second time when I was trying out the superpower app here, I think it conflicted with another app I was using, and it borked out my network connectivity. Somehow fixed that after a few reboots, and lots of messing around in the phone debug menu with the 3g/2g thing, it suddenly worked again.

I've not seen it manage to get onto 850MHz WCDMA in my house for a while, not since the mobo got replaced (I should qualify that with a statement on my bad memory ). It will occasionally latch onto something if I walk around the house, giving me a slow data connection with the G symbol showing - it will drop pretty quickly.
Messing around while I write this, I've just realised if I set my phone to GSM(2G) with roaming [Three UK phones need this on so they can connect to Orange towers], then it does establish a data connection at 1800mhz. If I force WCDMA only, I get NOTHING. Setting both/auto leads to it being dodgy/instable, as I've discribed above.
My Nokia 6600 supports 850mhz UMTS, which would explain why it's working well inside my house.
I don't think it's an app. I've flashed a few different firmwares in an effort to get this fixed, it's currently on official Froyo JPO (not even rooted!) with Multi-CSC and a few completely harmless apps. I'd try the stock Three firmware if it was available somewhere.
I'm hoping it's software like you suggest! I will tinker away for now!
Thanks for all the help, at least now I'm fairly sure I'm on the right track!

[Q] i9505 stuck out of service

Hi,
I have a weird problem with my S4.
At work I have some areas with really bad coverage so sometimes the phone can stay for a few minutes (or even say 1h) out of service.
This is all normal. The coverage sucks, the building is weird, not problem here.
The problem is that when I go outside where the signal is normally full it does not register back to the network.
Even more it does not even go to "emergency only mode". On a few occasions I arrived back home (10Km + drive) until I realized people can't call me because the phone is out of service.
What is even weirder is the fact that on some occasions, even though the (no service) (/) sign is displayed mobile data works just fine.
My previous iPhone did something similar too - it took a while for it to recover signal after exiting the coverage black spots but never more than maximum 5 minutes.
To me it looks like a radio modem issue and maybe this is aggravated by the fact that my carrier uses the same 2100MHz frequency for both Data and Voice.
I would like to know if any of you have experience anything like this or if there is some app available that can monitor what's happening.

what network and firmware you on and wich s4 variant:thumbup:
Sent from my GT-I9505 using xda premium

I9505XXUBMEA I9505OXXBMF1
It's Europe standard i9505.
Network is Digi.Mobil Romania - but I doubt it's relevant since it can't get even emergency only (other networks).

so... any idea?

Android needs to work on it's notification. No Service and the reception bars only gauge voice coverage. You can test this out by using Service Mode to do a PS Only (data) attach instead of the standard PS + CS (voice) attach. It'll say no service, but data will be fine.
Emergency only, is when there is coverage from other operators but not yours. No service, means your way off the grid.
I've noticed the issue you describe and it's only on some firmwares. Try a newer one and see if you still have the same issue. But you might notice a drop in your battery life because your phone will be scanning all the time. If you're happy with no coverage at work, best to just turn it off and then turn it on when your outside.
Best option is to tell your operator about the lack of coverage. There's someone in charge of stats who get's beaten every time you drop a call. You'll get extra attention if you've got other businesses around you, so let them know that too.

Thanks for the reply.
I am already on the latest firmware and I noticed the same behavior on the firmware before this one.
Unfortunately I can't try out other modem versions (from other FW packages) as that would void my warranty.

but...what about reboot phone? i know isnt funny but until u find a problem u can just reboot ur phone while u are going out from ur office...or just try to enable and disable airplane mode

Of course reboot works but I am looking for a solution, not a partial workaround.
The most annoying problem is that if I forget to reboot it when I leave work it will not recover network connectivity even if I am in areas with very good coverage, areas where you would expect your phone to work.
It looks like when it decides to give up it does not try again. It is very weird that it also drops the signal from other networks (the "emergency only") even if it's well in their coverage areas. I guess I will have to switch phones... Even if this issue was present for the iPhone too it never took more than a few minutes for it to recover on its own. And I'm not an apple fan

Just to do some brain ecercise...do u keep in power save when u are out of signal ? Its possible that disable check after few tries
Sent from my GT-I9505 using xda app-developers app

It's not in power save. I only use that function in case of battery emergency.

Same problem here
Hello, I have the EXACT same problem here. I am in Argentina.
Now, I've been in the USA for a few weeks, visiting, and while my phone was roaming, I didn't have a single problem with my phone.
Since I came back, 3 days ago, I haven't had any problems in Argentina, either.
Is it possible that something got activated when the phone was registered to another company? (it was AT&T i believe)
If that's the case... maybe you can try putting a sim card of another company and see if you still have the problem?
Please let me know if you still have the same problem or if you got it solved. I would love to know something more scientific about all this.
I don't know if this is relevant, but my compass is off by about 30 degrees. Maybe my phone is defective?
THANKS FOR ALL YOUR HELP YOU CAN GIVE ME WITH THIS

Hi I have similar issue,
My phone says its out of service or no signal or no network also I checked my sim card in other phone in the same place and it is fine. The i9505 model in ireland meteor provider was running ok until deicided to give a try to another network operator, when I changed the sim card it didnt only catch up the signal from new network provider but also it refuses to catch the old network provider. Funny thing is that I am receiving 3G but no signal bars and no service sign is beeing displayed. I am running latest official BTU (UK) firmware, the phone was never rooted, altough I had to remove the simlock and instal unbranded firmware. The phone worked fine with the newest updates for a month and now I am facing this trouble.
No factory resets nor installing same radio (couple of times) have helped. Also I used odin to instal same firmware (as it has locked bootloader) so I cannot revert back to other stock firmwares, but still no joy.
hope that someone faced the same problems and describe how to solve this issue. thanks
