Signal drops completely - HTC Desire SSupport

    I have a new HTC desire S on O2.

    I've noticed a couple of times in the last few days that when I go to use my phone it has absolutely no signal (no bars showing and a small "x" by the signal bar indicator).

    This has happened in a place where I always get full signal and HDPSA internet connection. It is not resolved by moving the phone, in fact it appears the only way of "clearing" this signal issue is to try dialling a call, which instantly makes the full signal reappear!

    If I haven't looked at my phone for a while and this occurs, I could end up being without signal for lengthy periods of time, which isn't ideal!

    Any ideas? Anyone else experiencing the same problem?

    Thanks in advance!

    (Starting to wish I'd stayed with my iPhone :-( !)

    I am having exactly the same problem to, over the last couple of days!
    (before that it's been fine). It's been happening mostly when I look at
    my phone in the morning after not using it over night.

    The only way I can get a signal back is to turn the phone off and on again.

    My concern is that if someone needs to get hold of me in an emergency
    that my signal may be down. And I may not look at my phone for a few
    hours and only then realise the signal is down..

    I hope someone knows why this is and can help get it sorted.

    I thought it may have be something to do with the software update
    that I did last week.

    My sofware versions are:

    Software Number:
    Baseband version: 20.28I.30.085AU_3805.06.02.03_M
    Kernal version:
    Android version: 2.3.3
    HTC sense version: 2.1

    Thanks for the reply.

    Interestingly, I am running that software build too - I updated it a few days ago, and have also only noticed this problem after the update had been installed.

    Thinking it maybe worth making a call to HTC?

    I'm having the similar software version since June.

    It has been working perfectly till yesterday when I came back from neighbouring country. I was on roam and when i got back to my country the signal failed to register to the local network. Had to reboot the phone to get it done.

    Today I realise again whenever I go to area where there is no reception like in my office elevator, it failed to capture the network automatically. Even when I tried to do it manually it dave an error message. The workaround is to reboot!

    I strongly believe it's the fone as my wife who travelled with me has no issue with her iphone4 using the same service provider as me.


    I've narrowed down to phone issue. I removed the SIM and placed in my NK71. From a no-signal status it automatically scans and logged on to the service provider network. Guess I have to pay HTC a visit :(

    In ' Mobile Network Setting' what have you got selected under 'Newwork Mode'? I have mine set to 'GSM/WCDMA auto'. If this isn't selected then I too have found very little signal stength shown, in many places.
    I, too am with O2.

    It would help if you folks showed, in your profile, roughly the area in which you reside!

    I have now shown my rough location (Berkshire UK) in
    my profile.

    I can also confirm that my "Network Mode" is set
    to: GSM / WCDMA auto

    I have just checked on
    and there now seems to be a problem with the
    phone mast local to me.

    below is message from the above o2 status page
    when I enter in my postcode.

    "Sorry a phone mast close to you isn't working.This means you might
    experience problems making calls, using the internet, or sending/receiving
    emails in this area.

    Updated 12:08 (refreshed hourly). Recent faults might not show yet."

    I wonder if this could be the problem? and they have only started looking
    into it after the weekend.

    I guess I will have to monitor it after the problem has been sorted out
    to see if that was the problem, or if it continues on after the mast is fixed.

    I also have the auto option selected.

    This fault has happened at both my home and work locations (Suffolk and Cambridgeshire). Have checked and there are no known faults on the O2 network for either location.

    I called HTC today, and they say they have had no other reported problems - but that''s what they seem to say to every fault!

    They have suggested a factory reset, as apparently the software upgrade may have got corrupted on downloading.

    I have now done the factory reset (much to my annoyance, as it is taking ages to re-personalise my handset), and will wait to see if this occurs again.

    I find fast internet access with these phones is very iffy depending where you are in the house and location, generally. The other day I was in a usual haunt of mine. i.e the De La Warr pavilion in Bexhill. Their caf

    This problem has just re-occurred despite performing the factory reset as advised by HTC. Oh well...I will be on the phone to HTC again tomorrow and will update this post with their latest response.

    A quick update.

    I had a look at my phone this morning and to my amazement the signal was still up,
    even though when I looked at the O2 status page it still showed there was a problem
    with the mast.

    Hopefully it may be something that they have been tweaking on the mast that has
    stopped the signal from dropping out, but they are still currenly working on it, therefore
    it is still shown as a work in progress on the O2 status site.

    I will post back if I have any further problems.

    I'm in Singapore so my issue could be unique! :)
    Anyway I bumped into a posting in another forum. He had switched to GSM ONLY and get better reception.
    I tried that with my S and it got reconnected automatically once I came out of the elevator. Still, it does not resolve the main problem using GSM/WCDMA mode.

    Ok, just to let you know that this morning I looked at

    Hey Solorize

    Thanks for the update.
    Woke up this morning to alao find no signal again - no idea how long it was off for again this time.

    "Reset" instantly when I tried to make a call.

    Will phone HTC and O2 today and post an update on here.

    Am so frustrated. I unfortunately got issued 3 faulty handsets since upgrading in July. This handset is only 2 weeks old and was working perfectly before the software upgrade.

    My internet connection is now showing 'E' rather than the usual 'H' that it does if and when I can get a fast internet connection. I'm on O2 also.
    That's not all as my Vodafone Mobile Broadband connection is mysteriously very slow this morning, as well! The end of the world as we know it. :eek:

    Just woke up and had a look at my phone and again I have no signal :( this realy is annoying. I am sure there must be lots of others who are having this problem =\ I guess it could be something specific to the software and O2 network? Or have other ppl on a different networks experienced the same problem?

    I thought I would try something out this morning...
    I did not reset my phone so I still had no signal when I left for work.
    But when I got to work the signal came back! So I guess it must be a problem
    with my local mast and possibly not the software.

    I guess the only real way to see if its software or the mast is wait until the
    mast shows up as no problem and is fixed. As when I look on the O2 status
    it is still showing up as there is a problem. I wonder how long it will take them
    to fix it =/

    I was on the phone to HTC for ages yesterday. They conceeded that there software update could be responsible for the problems I am experiencing with my phone (and yours Solorize, and with ercm03 post - it appears it is definitely the latest update causing the problems).

    I have also noticed that since the software update, some of my calls go straight to voicemail even when I do have full signal. You may want to keep an eye out for this Solorize ?

    Anyway HTC said that I should speak to O2 to get a replacement handset. I said I did not believe it was O2's responsibility to replace it as it was HTC's software update which caused the problems. My call got escalated to a manager, who still insisted that O2 should sort it, so I have asked for my call to be escalated to the next level.

    Will keep you updated !

    Unlikely to be an O2 problem as in the xda thread I linked to above one person was from Brussels and one from Latvia.

    I tested two phones side by side on O2 when I was running 1.47 in the HTC - calls would go to voicemail on the HTC but connect on the other with no problem. I'm pretty sure that HTC, probably by tweaks to conserve power, broke the network reception so the phone thinks it has no signal when it has. This is why re-registering on the network fails (as it *is* registered) and why sometimes incoming calls fail but outgoing ones are ok.

    For me, and at least one other person, removing 1.47 and returing to 1.28 fixed it.

    You might think that I am foolish but am vary wary of all updates to anything especially to computers and their like. Only very rarely do I update anything until after many months and some internet research can I be assured that everything is OK and doesn't corrupt anything that I own.
    I guess that if you're a computer wizz kid then take the risk, I suppose.

    Quick up date..

    I have noticed that throughout the day (at work) my phone has
    been loosing signal, so I guess its not down the the problem mast
    near my house =(

    If I was going to try to revert to my previsous versions that were
    installad before this update, how would I know which versions were
    previously installed?

    And how would I go about getting and installing these version
    back onto my phone. As I have not done this before and does
    the phone have to be rooted? if so how would you do that.
    Sorry for all the questions but just want to make sure I dont
    mess the phone up anymore than it already is ;)

    I followed the guide posted here stopping after step 11.

    I would guess the RUU you want is the O2 one here (7th down).

    Newbie here.

    My girlfriend has just acquired her first smartphone - HTC Desire S - but is not techie at all. I have an iPhone 4 (I know!) so no experience with Android at all. We're both on Vodafone and noticed that her phone showed no signal and, when I phoned the HTC from my phone (1 metre away) it went straight to voicemail - meanwhile I had an 80% signal, which is typical in our house.

    I had tried calling her earlier in the day when she was in a different location, and the call went straight to voicemail then as well.

    Any thoughts or suggestions?

    Go to Settings->About phone->Software information

    I would guess your s/w number is - see above posts about this.
