Hello .
I've got a problem with a random signal drops. The interesting fact is that it has started about two weeks ago when my phone was just laying on the desk, no moving, no touching, no ROM change, just nothing unusual. In random moments my phone shows "no signal" , when I try to set the provider manually, sometimes, after about 2 minutes, gets the signal, but although it shows full signal, the connection with internet is really slow, the quality of phone talks is pretty poor and text messages doesn't always want to get sent. I didn't notice any special places where I have a signal and where i don't. I've even gave my phone to repair but they said that the hardware is fully functional and they dont know how to fix that problem, I've changed ROM - still no effect.
I hope that somebody can help me, becouse that's pretty irritating .

Title - meant to say randomly lose service and have to reboot
I have only had this happen about 3 times since owning the phone (since two weeks after launch). Occasionally, my phone will altogether lose service and display the blue circle with a slash through it, and I have to reboot the phone to regain service. This happens in an area where I have signal usually, when this happens. Does anyone else have this issue?
I had a problem similar to this last night/this morning. I didn't make any changes/mods to the phone either...
Phone was on the charger last night and when I woke up this morning I noticed I didn't have any emails. I still had the 3G icon and 2 signal bars, but anything I would try to do using internet connectivity wouldn't work (checking mail, navigating to google.com, etc.). I just shrugged it off since this has been the first time it happened.
For what it's worth, I'm running JF6 with UnleashTheBeast and the circle battery meter thing...
RE: Network loss, etc.
I've had issues like this from day one. From my testing, it seems to be related to the radios. (Both wifi and 3g.)
Stock was horrid for me, but then again, I live/work in a place with really crappy radio reception. It was tough to tell if the 3g or voice network service losses were just "the location" or something with the phone. But the fact that it's doing it with WIFI when I'm 3 feet from my AP, and no other devices are having issues is telling. Things have stabilized a bit with one of the SRE 1.2 OC builds.
That, and I'm now having intermittent sound issues too. (Can't play ringtones for a few minutes, then I can, then I can't, etc. )
I'm actually starting to suspect it's relating to the blocking filesystem lag. Almost as if some app is just killing the FS. I'll keep investigating. But it's good to know I'm not the only user who is seing service drops in strange ways.
I'm having similar issues with data connection, and i'm completely stock at the moment. My coverage is great so it just doesn't make sense.

Yeah, it's completely random when it happens, and it has happened two out of three times in an area where I have service...
Hi all, please welcome me whom had bought the Optimus 3d just 2 days ago. I love this phone. Please do let me welcome you all to talk about a flaw, which I've found out right away with the new phone since 2 days ago! I've been with some others Android phones, so, I should say I've had good experience with Androids.
I realized that Optimus 3D has some kinda hardware Radio receiver flaw (I really don't know what should I really call it) similar to the famous iPhone 4 dilemma in the beginning. I found out that the "Radio receiver" is located somewhere at the bottom of the phone, where our hands most often holding the phone with. The hand will block out the signals and the signal bar will be reduced by a lot as much as to zero (if the signal strength itself is not strong in the 1st place!) Try find this yourself, have some experience by holding the phone at the bottom and let go and holding the phone and again let go, keep trying this you should see the signal strength that will drop and rise and drop and rise again. Or is this only my phone? But I've never experience this phenomenal with other Android phones!
Also, I don't know this has the directly link to the downloading issue or whenever browsing nets, the network data will drop very very often. I hardly got successful downloads from the market without few retries. Thank god at least at the moment I can temporarily fix it by turning off and on again with the data enabling shortcut in the pull down menu.
Please help me here and advice! Very much appreciated!
Since the famous iPhone 4 drama for a lot of phones these stories pop up once in a while. I know lots of people furiously believed the Samsung Galaxy S had the exact same problem but after a week or so nobody ever talked about it anymore.
I myself have absolutely no problem whatsoever with the signal, not even when I completely cover the entire phone with my hands leaving just a small spot to read the signal it never drops, not by one bar. I've never had a single download dropped with either 3G or wifi and I've downloaded my share of stuff from the market and other places.
I've tested this with my T-Mobile simcard (which has pretty horrible coverage here) and with my Vodafone simcard (which has great reception) and with both simcards the signal strength stays exactly the same according to the bars. Even when I go to the settings the dBm and asu values stay exactly the same, no matter how long and how bad I cover the phone.
So far you're the first and only person I've read about having these issues so I think it just could be an isolated incident, although that would be bad for you as that would mean you could have a defective phone
This problem is not something new and is not related with O3D.
All the phones have the same issue.
It is normal that if put your hand on the antenna the reception will drop.
The radio waves just work like this.
However the atenuation from your hand is most accentuated on higher frequencies like 2100Mhz.
On every phone even on the oldest phone with external antenna you will meet this phenomenon.
The difference between 4 bars and 1 bar is only around 10dBm which really isnt that massive a drop at all. Now that you've pointed this out i do see that the signal strength varies a little depending on how you hold the phone but its not enough to panic about i don't think. The iphone 4 problem was significantly greater in that the iss was that a user's hand would electeically short the mobile network antenna to the bluetooth and wifi antenna causing a total loss of signal. While 10dBm or so is a definite dip in signal strength, it's an acceptable level of attenuation and i dont see it causing any real world day to day network problems that you wouldn't experience with any other high end smartphone.
My workplace is in a giant tin hut of an industrial unit (read: faraday cage) and today while i had this phone there for the first time i saw no noticeable network coverage problems. The behaviour was as far as i can tell exactly tue same as my motorola milestone from which i upgraded.

As stated all phones can lose a bit of the reception when it's in your hand depending on how you hold it, the reason Iphone4 was such a big deal was that it was extremly sensitive when it came to left-handed people and they had a real problem with their antenna being totally blocked when holding the phone normally when speaking in it.
Later on media and uninformed people started fueling the flames as soon as they saw a bar drop when picking up the phone, radio waves are not magical rays or tachyons that can move though matter without interacting with it.
thanks for all the replies. Believe me or not, this is the 1st phone I realize this issue and it is so obvious, the bad news is, it is really bad for me that the antenna is located at the bottom, probably most others phones I've owned were at the top as a result i didn't got any problem before.
And another issue, I'm pretty stucked with the shipped rom now, really hope to see custom roms soon. I'm at the moment totally freak out with the inconsistent of data and the wifi, it keeps failing me, this really freak me off, what the hell is happening to me with this phone! I've never ever got any dropped data or wifi connections before. Arggghhhh!!!!!!!!!!!
I have no signal drop out no matter what hand positioning i use..
I'm in a very poor reception area. I do notice hand over phone a drop from 1 bar to none. Still not a red cross to indicate no signal but a drop of 1 bar all the same.
Just tested it.
Signal drops from 4 bars to 3 (1-2 in awkward positions) when hand-held. Not an real-life-usage impact though...
Thanks for all the test replies to support my findings. OK, now, I've realized that the hand holding issue has no direct impact to data drops. And the data drop is entirely due to the time issue which it does not lock down the data connection when swithcing data modes. And at the moment it can beasily over come to turn off with the data button in the pull down menu. I'm not sure though when in the situation when the signal strenght was so low, by holding with hands will give an direct effect of data drop or not. Will observe that
Hey guys.
I have noticed large variations in the signal that I have. E.g., somewhere that I normally have 2 bars, from time to time it may display 5 bars or no bars at all, but I can still make a call.
The real problem occurs after long period on standby, after which it seems not to recognize my sim. It has happened 3 times in a 4 day period. The problem is solved if I restart the device or disable-enable the plane mode, but this is not a real solution, since meanwhile I've missed a few calls...
I have no weird apps installed, and I am experiencing the signal variation since day 1, without any apps installed.
Any ideas? Contact the retailer maybe? I bought it from expansys on April 11th, what is their DOA period?
Contact HTC maybe? Or get a new sim?
Your help is highly appreciated!
I suffer signal variations too, I can go from 5 bard to 2 bars and back all in the same location.. Ive never had 0 bars, or had a call drop. But its something that bothers me
What you should do is
Check with your provider for any faults in your area
Request a new sim
Contact your retailer
contact HTC
All in that order.
I also have this problem. I have tried a new simcard but still problem. I hope HTC will solve this, because it seems to be a software problem.

Thanks for the quick answer.
I do not mind the signal variation, since I can make calls even with 0 bars (!), of course I don't know if this affects the battery life...
My real problem is, not recognizing the sim... I also forgot to mention that the very first time I inserted my sim into the phone, it didn't recognized it either.
I 'll get a new sim from my provider, hoping it's not the phone's fault.
In the meantime, I 'll let the retailer know about the situation and ask about the DOA period, in case that doesn't work.

You mean, just the signal variation, or the sim not recognized after standby?
you should rly try to get new sim card, could be sim problem.
For signal variation, it probably drains battery life. If signal is weak, or it drops from 1 bar to 0, then back to 1 (had this situation at my work) - battery gets drained RLY fast.
But that was in case when I rly didnt have or had rly weak signal. Dont know with this, but I guess if phone trys to "recover" signal, it will consume much more battery

The SIM problem is a separate issue, which you should hopefully get fixed.
Now regarding the signal strength bars. I have used a lot of expensive RF test equipment. Most of it more expensive than your car. Or house.
None of them measured signal level in "bars", usually it was dBm (mW in 50Ohm). Unless you know what those bars correspond to in real power levels, then it's rather hard to say if the variation of a few bars is something to worry about.
Digital comms systems tend to go from "working great" to "no signal" within the span of 6dB. And that's a very small range when one looks at the variation of signal level in a typical urban environment, even if the phone is static (position-wise).
It's been some days now and I don't have any more sim issues, so all good.
Maybe it had sth to do with where the sim was touching the phone... (I tried cleaning the sim and reinserting it a couple of times)
But the signal variations continue... I reached HTC and they said to try GSM only mode, and also safe mode, but same behavior there. - now rechecking and unsure about results, gosh it seems complete random.
aza314, I understand what you 're saying, but what about this... the signal variations are so annoying, that rarely I might unlock my phone to get a temp "no service - emergency calls only" message (normally I have signal again in 1 minute or so), in the same spot I was making calls normally some minutes ago (or later).
Guys, I need your input here... if you have never experienced such a behavior on your phone, if it's not a known bug, I need to know, in order to report it DOA.
edit: on the other hand, maybe it's related to this issue, so hoping to get fixed in the first update...
My new phone is exhibiting strange behavior that I haven't seen any postings about. (okay, one posting, but it didn't have any replies http://forum.xda-developers.com/showthread.php?t=660243 )
I had a Note 2 (AT&T) that worked great for about 6 months until the usb port died. Several ROMS, several modems, no signal problems.
I warranty returned it, and new phone constantly loses or maintains a week signal, until I make a call. Using data, the signal stays pretty weak, and drops a lot. Typically around 1 bar. Browsing the web, the pages hang for minutes at a time. Outbound text messages frequently fail with an error. Incoming calls frequently go straight to voicemail. But, if I dial voicemail, the signal bar immediately jumps to full bars. Now I can hang up, and use a strong data connection for about 3-5 minutes, until the signal slowly drops back down. Toggling airplane mode, or rebooting does not seem to jump start the signal. Making a voice call though, jump starts it immediately every time. Additionally, the battery life seems to be much worse, but I haven't actually benchmarked it. It is the battery from the original phone.
I've tried the phone bone stock with the latest 3 modems, and with CleanROM and latest 2 modems, and with stock and Adam kernels. The behaviour is exactly the same in all cases. It's like the radio just sort of goes to sleep until I make a call.
At first I just assumed it was a hardware issue, because the old phone worked just fine, but the fact that a phone call wakes it up makes me wonder if there's more to it. I took it into my local AT&T store and they found the IMEI was listed as the old phone, and corrected it. Of course, my phone worked perfectly in the store, even before the IMEI change. I figured that was the problem though, and it actually seemed to work for the rest of the day, but the next morning it was back to a weak signal.
At this point I guess I'll return it, and try another one, but I figured I'd check here and see if there was a better solution.
Hello,
I updated my Xperia L to 2.17 yesterday,and today,about a few hours ago,my phone lost all signal.
How it happened was weird though-
I first noticed this when i tried to make a call and it wouldn't go through.At that time,the signal bars were full.
Then,i tried to send a text message.Same issue-not delivered,with the signal bars still full.
I thought it could be network issue and put the phone into airplane mode and out of,about 3-4 times.still the signal bars are full,but no call/message was going through.
Fed up,i rebooted the phone twice.Same status! .signal meter is showing full,but no calls/messages going through.
Then,after 5 minutes,the signal meter showed no signal-emergency calls only.
then,about half an hour,network came back up and i was able to use the phone as usual.
It couldnt be a provider issue as another phone with the same provider sim worked fine.I also had plenty of talk-time left so,its not an issue of that either.plus,i was in direct line of sight of multiple towers.
for some background-the sim is about 4 years old.plus,to get 3g working on my phone,i had to play with the settings a bit and it could only be activated after my service provider did some hocus-pocus.since then,i got fed up with their ridiculous prices and shifted back to 2g.
The same sim was in use in a hardy nokia1100 and then a Nokia 6020 till a month back,when i got the XL.and never have i faced such an issue before.
Is it a phone issue?I have attached a screenshot of the battery usage-it shows the network issue in red.
http://forum.xda-developers.com/attachment.php?attachmentid=2177124&stc=1&d=1376067822
Initially,i neglected this in the battery page-this is not the first time the battery page shows network was dropped.it has happened multiple times before,only-this time,i saw it happen live when i was using the phone.so,its not a sudden issue and has been there for a bit of a while.
Another fault i noticed sometimes-when i receive a call-it drops off and i have to dial them back.
However,if i were to make the call,it works just fine.happens very rarely though.
so,do i change the sim or go to the service center?is it a radio/antenna issue?
Kindly advise,
Regards
Suraj
Sorry for bumping old thread. but i got same problem here.
also we are not along. https://talk.sonymobile.com/t5/Xperia-L/network-issue-with-xperia-L/td-p/405833
