Hi!
I have my Xperia S for about 3 months now (12w07, currently on FW .73), and I am 100% on original firmware, never rooted or flashed, never installed "pirated" software.
The problem:
My number is out of reach. Although the phone operates COMPLETELY normally (even receiving e-mail via wifi works, programs run smoothly), although the signal bars show FULL signal strength, signal reception & transmition do not work at all. When being called, it reacts EXACTLY as if I was in a NO signal area (the operator says unreachable, not switched off). This will continue until I restart the phone, otherwise the signal never comes back! Today, which was the second time that this happened to me, I was of-network for approximately 4+ hours! Darn!
Anyone else experienced this?
FYI, my SIM is an original MicroSIM, not a cut one...
Check your SIM, might be something wrong with that.

I have had 2 different vibrants now and they both have done the same thing. I haven't been able to isolate the problem to any one thing so I ask if there is anyone else experiencing the same problem. My network connection just freezes. I can't call or text and I have no data. If I try to make a call, it freezes on dialing and the only way to get it back is reboot. This is happening about twice a day and is really a pain. The only way I know it has happened is by trying to make a call and it freezes. I don't know how long it has been that way and when people try to call me, it goes straight to vmail. I put a new SIM card in thinking that was the problem, but it didn't help. I have searched everywhere trying to find a fix. TMO CSR was absolutely no help at all. Shocking.
BTW I am in an area with no 3G coverage. I am on EDGE all the time.

Since you have had the problem now with two different phones it could be a result of some app(s) you have installed, or related to your coverage. Did thr problem start after having each phone for some time?
I am working on ruling out an app. Weird thing is, I have had winmo for over 3 years in the same area with no probs. This is my first android. I am uninstalling an app at a time to figure out if it is one.
****Update****
So I uninstalled the ESPN Scorecenter app. I haven't had a freeze in over 24 hrs. Guess I am going to have to find another app to follow the games while I am at church.
are you sure u r in area that has only Edge? have u try to Lagfix the fone?
goodluck.
This just happened to my wife's Vibrant. This reminds me of when I had the T-mobile Shadow, where suddenly, it would not be able to send or receive data or calls BUT the phone itself shows no indications of any signal problems. It's as if the cellular software component has frozen and so the signal bars are frozen to whatever state they were and thus tricking you into thinking everything is fine until you try to make a call or someone calls you on a landline wondering if your cell phone is dead.
I suspect it's due moving into a poor or zero signal area and the phone tries to make a data connection. I really have no idea how to fix this other than to hope there is a firmware update to resolve this. The only fix is to reboot the phone (flipping the phone to flight mode gets one to a state where you can't turn flight mode off... which indicates a lost of control to the cellular component).
I am consider finding a way to reboot the phone nightly, which will help if this happens overnight, but I wish there was a way to detect this more immediately so it can reboot when needed. Perhaps an app that monitors the carrier signal strength and if the signal level is perfectly the same for a long duration, then a lock up of the cellular component is suspected.
I'm on Vodafone UK, at some point this afternoon lost my signal, just had the no signal icon when I checked my phone.
I didn't change any settings, it was working fine received a couple texts, went to reply later and had no signal.
1st I tried going to settings->wireless settings and switching phone off and back on, no joy.
2nd tried Switching phone off and on, no joy
3rd tried settings->menu->all setting->personal->phone->network change network selection to maual, then select vodafone UK from list, still no joy
4th put network selection back to automatic, no joy.
5th turned data connection off no joy
Put my sim in girlfriends unlocked Nokia worked fine and I could make a call.
Returned sim to my phone.
I have noticed it will stay on no signal for ages, then will be trying to find a signal, will appear to have found just a phone signal (full strength) but attempting to make a call will just sit on the dialling screen for ages but never connect and then gives up without an error message after about 40 seconds. My data connection is off when it finds a signal, if I switch it back on it seems to be trying to connect GPRS then after a while back to no signal. Leaving it alone when it appears to have found a signal it stays for anywhere between a few seconds and minutes before going back to no signal.
Sorry my post isn't easier to read, been up since 4am getting tired now, and my phone is doing my head in.
Just to stress again my phone went from working to not just sitting on the table no settings changed or anything. Please help
I had a similar problem to this after flashing a ROM. My signal will be ok for an hour or 2 then disappear, never to return. If I switch 3G off it seems to solve it for me.
Me too
Xenton, I'm on VF UK with 1.72 ROM, and also have random signal drop outs. It happens even when static in the rear part of my house where I can see for 30+ miles and must have line of sight to multiple masts. The coverage maps on VF's website say the phone should be getting good signal, but sometimes, as you say it drops out, to return soon, later, or (but only very occasionally) not at all. I hard reset my phone a short time ago, so I'm pretty sure it's down to the ROM/radio. I've the feeling it's something we just have to live with, unless we wait (forever?) for the VF UK 3.14 ROM or install the WWE version.

Hi,
Thanks for the reply. At work this morning my phone was working fine, then when I returned home same problems, no resets or changing to settings. All this makes me think it is a problem with VF, I have posted on the eforum but this is my second day without a reliable signal at home now after 2 years faultless coverage at home. If it keeps up, I may have to drive to a signal and call VF. Did you get your phone through VF, if so you should get onto them for a replacement or repair if it is your phone.
One other curious thing today at work I got some txts from VF which automatically change setting for mobile internet and picture messaging. They still worked fine at work, but I hadn't requested the settings be sent and the old ones worked fine, but then so do these new ones, just not at home, where I am mostly signal-less.
Xenton,
I used to be unable to send MMS's until I hard reset my phone. Oh, and despite requesting the MMS settings via the customer services and the VF web site, nothing ever arrived on any of the occasions it was supposed to.
I'm out of my initial contract after a year, so think I'll do well to get a new hand set. It's more of a relatively minor annoyance, as opposed to what seems like your more significant issue.
It only really happens a noticeable amount at home, so I’d put it down to something to do with the number of cells my phone could presumably see, and perhaps it getting ‘confused’ (?).
I’d be interested to hear what you find out on this, if you reach a resolution/find a solution.

I have noticed that once the signal is lost, sometimes the xperia mini can't find the signal again. You are left with the little yellow triangle in the notification bar, but until you toggle the radio on and off, it will not find the network! Or is it just mine, latest firmware on 3 in the uk.
I have not noticed complete loss of signal but even if its laying still on my desk it keeps going between GSM and UMTS for no reason at all (xperia mini pro model). My old X10 mini pro on the same spot on the desk was rock solid on UMTS.
I also noticed that it sorta gives up searching for a signal after a while. I guess it's good in the sense that it'll save battery...

Same here, also on 3 network in UK. Actually it's on my OH phone so it's imperative I get this fixed ASAP!
She has discovered that it also affects texts and Gmail too, nothing is sent or received until the yellow triangle goes. She has discovered that if she tries to make a phone call (but not needed to actually answer the call, just wait for the call to start ringing and then hang up), it clears the triangle and the phone reconnects to the network again. Then she will receive any outstanding texts and emails etc.
I wonder if this is a 3 network specific issue? If so, then I am sure flashing a custom ROM and Radio should then fix this issue?
Actually, you know what, I think you may have a point there with it being with 3, cos I had major problems with this 3g H H+ switching issue on my galaxy s 2, it seemed to only affect some ppl on some networks, 3 being one of them, however, I also have a galaxy s 2 again now, and now, (a few months on) it seems to have fixed itself. A lot of the networks, it seems are rolling out software updates or changing actually hardware to get themselves up to speed with protocols such hspa+ so it could be something that irons itself out eventually. Lets hope.
I have the same problem. The duration of loosing network can be shortened if you set WCDMA or GSM only. In case of choosing both of them the phone switches between and can loose the network for a long time. But even if I use GSM only after loosing network it can reconnect after 1 minute and more. It annoys me in the underground - the cells are located at the stations so the phone sometimes can not connect to the next cell on the station during passing it and I have to wait for the next station for recovering of connection.
Hi, I also have the same issue.
Sometimes I turn the screen on, I see a yellow warning in the status bar and have no signal.
A few secons later the device is registering again in the network.
I observed that the signal is also not very stable. There are many signalchanges on the same position, between cdma and gprs (3g,hh,edge)
I don't think it's the Provider, because my old x10 mini pro as not the effects.
my Provider: Germany Telekom (D1)
my Firmware: 4.0.A.2.335
I have no idea what cause this problem. I hope it's the firmware. Maybe the rest can check if you got the same like me.
I have the same problem. Often the signal just goes away during conversation as if I went into a tunnel, even if I don't move at all and I am in the place where there is good signal. The call hangs and the yellow triangle appears. After 10-20 seconds, the signal is recaptured and I get full bars again. This is obviously some kind of software or hardware bug. It is as annoying as the famous noise problem and it MUST be addressed.
Yeah, I've got the same issue w/ T-Mobile in the US.
My G1 never had this problem...
This happened to me also with my ST15i mini. What I did, was i switched into manual in network selection from automatic and after which it never looses its signal.

I'll give that a shot. Did you also select GSM only, or did you leave it as GSM/WCDMA prefered?
edit: Doesn't seem like it worked... GSM only and T-Mobile selected manually, and I still lose network sometimes for no reason.
I also having the same problem on my sk17i...
Normally once I start holding my phone, the signal will completely gone
happened to me also with my sk17i.
Same problem here with my sk17i. That's really annoying!
Carrier: Orange
Firmware: 4.0.A.2.335
OS: 2.3.3
Yup. Happened to me aswell

+1 for reception issues in Australia on Optus on populated areas and even in the open. Shouldn't be happening. Still on .368 but.
Same thing here in Australia. signal is weak and sometimes it gone 4 ever with the yellow sign !
3G signal drops to me!
I have an ST15 using firmware 42, I'm in Brazil!

Hi, I have strange problem with my SGS2. While I'm in my apartment I simply can't use it to make phone calls.
Someone calls me, I answer, either by dragging or by pressing home button (I set that option in the call setting menu). But nothing happens, ringing stops, but screen stays the same, showing that someone is calling me, and of course, it isn't connected, no voice is coming through. I can drag answer icon all day long but it won't make it connect. If caller is patient enough it will connect after 30-60 seconds after I tried to answer the call.
Second problem is that if I call someone, or it connects us after those 30-60 seconds, call will simply be dropped after 5-10 seconds.
Signal is fine, 3 or 4 bars, when I'm somewhere else I don't have these issues. Few days ago I got called while I was in underground garage in same building I live in, there were no bars on signal indicator, but phone answered immediately and it didn't drop for those 2-3 minutes I talked. But When I'm in my apartment (I live on the 4th floor, there are no large buildings blocking the signal, and anyway, phone says signal is 3-4 bars...) I'm unable to make or answer calls.
This is from the first day I bought it, at first I thought it's something with network, that they were doing something, since my old HTC Legend had no problems here, but after a month it's the same.
Do android phones have radio "part" in their software? Like older WinMo phones did? I remember my yet older HTC Artemis had so I could flash other radio versions to get better reception and battery life.
Or does someone have better idea? Because I'm all out, warranty is useless since this isn't something that happens everywhere so I can't show "them" it doesn't work...
Firmware is stock, I debranded it from t-mobile to XWKE7, kies recognizes it so I think I did that part OK. But anyway, this problem is from day one, before I reflashed it for the first time.

Yes it baseband/Modem interchangeable and flashed as phone via Odin .
Question = Q&A section .

Thanks, I'll look if there are alternative software for baseband/modem. Hopefully that will help.
So I receive my Telus S3 on release day, activated it, and had no problems (that I noticed, but I was connected to WiFi most of the time.)
Rooted it about a week later, and I can barely get service. Rather, I'll get a couple minutes of connectivity, then it'll disappear for 5-10 minutes. It's not a corrupted IMEI, like this thread is discussing. I've since flashed a stock Telus rom on the phone, and I still have the same problems.
We have low LTE availability in the area, so I thought that may be the problem, but the same thing happens with setting GSM or HSPA in the network settings.

Sounds like a pretty curious case... have you uncovered any causes / solutions yet? Also, before you flashed back to the stock Telus rom, what were you using?
I have a similar issue happening also on my rooted telus phone. I rooted it the day I got it so I cant confirm on how it was before. It is running a stock ROM/kernel. What happens to me is my service will drop from 3 or 4 bars to no service or will show 1 bar but be unable to get any service anyways. Im not in an LTE area but I am in a dc-hspa+ area. Is this what happens to you as well?
The only fix I've found is wait 5-10 min for it to come back.
