[Q] No Signal, Factory Reset - Nexus 4 Q&A, Help & Troubleshooting

Guys
any of you had any bother with your mobile signal?
I'm on Vodafone and from this morning my signal bars are empty and I have no mobile signal.
I tried selecting Vodafone and Automatically select from the mobile signal menu, never made any difference.
I did a factory reset of the phone and it worked great, logged into google, restored my apps etc and it was all good
Then 5 minutes ago the same happened again, no signal and nothing I do makes it come back on bar another factory reset???
I've tested my sim in another phone and it is fine, no drop outs, no issues, I hope it's not a faulty phone (
Any one else had similar or can think what would be causing this?
Thanks

UPDATE -
Happened again, no signal bars, no connection
so this time rather than a full factory reset I removed the apps I had reinstalled, which were Spotify, Facebook, Twitter, Tapatalk and Whatsapp, rebooted the phone and my signal is back to full strength again???
Could one of the above apps be the problem?, is that even possible?

Its got to be some software problem.. These apps cannot cause such a problem

thats what I thought.
I've left the apps off for now, and if the signal seems ok after a couple of hours I will start putting the apps back on one by one and see if anything obvious happens.
The only App I thought maybe could cause it would be whatsapp as it ties in with your mobile number.....I'll see what happens throughout the day

happened to me once, all I did was put it into airplane mode and then back out of it again, and all was well

Same thingg happened to me. I'm on tmo though. Its defective. Waiting for replacement

I take it you've all changed your SIM cards to be on the safe side?

My experience is that the signal does have a tendency to drop out in weak reception areas and is slow to pick it back up again. I'm on vodafone in the UK.

I'm on orange and today I had nothing but problems. Dropping signal and everything I am not sure if orange is having problems. Had a HTC one s before never lost the little H above the signal bars.
Should I look at getting a replacement sorted.

I'm having the same problem with T-mobile in the US. It seems to mostly be an issue for me in areas of weak coverage. A reboot or any other way of resetting the phone connection fixes it, but still...

Been happening all day. Even now I have no mobile signal and yet I am on here using mobile data.
Usually a full reset would bring the signal back for a while then it would go again. On one occasion putting it into aeroplane mode then back again worked, but only the once. It looks like I'm taking it back this weekend unfortunately.

i had this issue when i first got the handset on o2, but after a while and me putting the o2 sim in, it picked up signal, swapped out for my orange sim and hey presto started working fine. It's been like that for a week now, but last night the battery died when i was asleep and after a charge this morning, no signal again on my orange sim. I'm in work now so cant swap out for my o2 sim as its at home, but will try and borrow somebody elses sim to test when they get in the office later this morning, Very annoying!

same issue discussed here: CLICK

Just tried another sim, o2 this time. Same issue, so back to shop on Saturday. Question is do I get another one or plump for the sIII or an htc

Carrier? Have you checked if they have problems?
Tried your SIM in a different phone?
Tmobile is the carrier..now i lost my signal all together....I dont have another phone to try my sim out on
ok...so both data and service came back for about 30 seconds...i got two white arrows going around in a circle like it was updating something then i lost all connections again and says emergency calls only
any ideas?
ok...i have this weird folder on my sd card named .android_secure...dunno where it came from looks new to me
data signal lost here
Hey, I'm having the same problem here, no weird folder in my sd card though. Went to bed last night everything was fine, woke up and my apn list was wiped.... I reset everything in the apn and still no data connection but I have service. I'm running the latest Cyanogen mod stable for nexus, almost seems like an update was attempted last night and since i"M not stock things went crazy....
Call t mobile and see if there is a data outtage.
I had no signal for like three hours last week.
tmobile uk? mines down too. manchester area.
sim cards do go bad.... i had this happen last year... maybe go to tmobile and see if you can get another if there are no reported outages.. the probably wont even charge you if you go to a corporate store
so i called tmobile and they said they knew what it was...had to turn my phone off for two minutes and still waiting to see if it worked..but i dont know why the sync or update arrows were showing up on my notification bar. sure hope it was Froyo passing me by

where are you, uk or usa?
I've had something similar happen to me as well. This was a few weeks ago. I live in Chicago, and use T-Mobile for what it's worth. I ended up pulling the battery for a bit and rebooting. I got the data connection back.
Sometimes though, the data connection will seem to hang a bit and I'll see the flashing arrows and sync icon as well. It seems random, but the last time it happened to me was yesterday.
back
It must have been a localized black out here in Washington State (US) because my data connection came back on just now after 3 hours of being shut off. For awhile there I only had edge and no 3g and without me doing anything 3G and H have connected back on.
Well that's good. The optimist in me says that the outages and weird issues are related to the upgrade of HSPA+ for us Let's hope it's true.
I had the same problem in WA. Data has also been restored here.

Data Issues??

Occasionally I get no data connection & I have to restart the phone, does any body else have that issue?

I have that issue as well, idk why it happens but I'll add it to the list of problems for when I call to get a replacement.

That just happened to me today also. It switched from "H" to "E", then when I opened USA Today it FC-ed and the icon turned into a generic Android one like the app was on the SD card and unavailable (even though it's installed to phone) and then 5 more background apps that I didn't even know were running FC-ed (Amazon MP3, Finance, QuickOffice, something and then Facebook three times?) and the phone locked up. I was able to power off then back on, but data never came back even after waiting about 10 minutes until I powered off and on again. Quite odd.
I get the same issue where am connected to wifi and as soon as i walk away from it it doesnt connect back to the data network. I got a replacement phone coming so hopefully i dont have the same issue. Another thing is the random reboot and i get black screen a lot especially after rebooting

I've had the issue, but each time it appears to be related to JuiceDefender not properly enabling the radio. If I shut JuiceDefender off, the connection comes back, although sometimes its just easier to airplane mode it and be done with it.
I called T-Mo about it, they said call about a week after the inital release date and see if they have a fix by then, there isnt enough information kept since it hasnt been officially released yet.
I'm having the same trouble. Are you guys on the new sim card? I popped in the new sim card and the tech told me to not use it and just save it. I noticed when I put the new sim card a notification of a new voicemail came on. I didn't have any voicemail.
Edit: I'm starting to have some serious data issues. I'll get cut off, but my phone will still show full bars and "H". I try the whole airplane thing and it still does nothing. I constantly get the "check network setting, try again or cancel". My market wont load, browser says "unable to connect." This is getting stupid. When I call T Mobile it always start working and then cuts off shorty after hanging up. I've never had this isssue before. I live in the middle of the city. Only 3G around here. Its getting annoying.
Guys I'm afraid that it might problem with the antenna placement. Holding the phone on the bottom half will drop me from 3 bars of "H" to 4 bars of "G", then it will bounce back up to 4 bars of "E". If left on a desk then it will remain at 3-4 bars of "H". I notice this especially at a place where I have low-mid signal, such as my school (reinforced concrete FTL). When I have a strong 4 bar signal, it usually won't drop all the way down to edge but I do loose a few bars. I hope a simple software issue is enough to reduce this effect. I might be being crazy paranoid but I'm definitely noticing a lower signal than on my G1.
Try holding the phone by the edges, then hold it in a normal grip and see if the signal strenght changes (Menu->settings->status->signal strength)
I just got off the phone with tmo and was told its a known issue with the network affecting about 10% of users. The issue started for me yesterday on my hd2. He also said they have people working on it. I asked if I could get my buyers remorse set back 14 more days to ensure the issue is not permanment but he said that they are no longer doing extentions. I'm sure if I get tranfered to retentions the answer would change. I hope.

I'm also having the same issue. I just rebooted my phone, so I haven't had the chance of switching airplane mode on/off yet. I'll let you guys know if that works for me, either way, I'm hoping there's a fix from T-Mo.

Wow that's funny, my MYTOUCH does the same thing with airplane mode off/on. I also remember that the store demo g2 I played with last night had the voicemail icon in the notification bar, but when you pull the bar down, there's no option to connect and retrieve the voicemail. I found that even weirder since the phone comes preloaded with google voice.
Also experiencing the same issue here in Phoenix. Been having it since I got the phone on Monday.
I have been in an ongoing round of tech calls and will be having a follow-up with the tech who I spoke with last night... I've tried everything from APN resetting to swapping the SIM card to a total factory wipe -- nothing is changing this for me.
I *know* my neighborhood has full 3G access, but I am maxed out at 1 Mbps. (Before the factory wipe I was getting 0.35 Mbps.) If this doesn't change I may just return the phone and switch to Sprint to get the Epic 4G. I mean, I'm not getting HSPA+ coverage either way, and at least with the Samsung Galaxy S Pro I'd have a full 5-row qwerty...
>_<
Wow, this is really too bad. I was SO excited about this phone...

If this happens, try going to settings->wireless->mobile network->network operators and see if you get an "Error while searching for networks" error as I did.
Reset fixed for me too. But it makes me worry.
I'm on a brand new sim card (switched to TM from ATT). I'm having some data issues too. I talked to TM tech support and they reset my connection but that did nothing. Now they're going to their android techs to see whats up.

My Omnia 7 keeps loosing it's 3G connection

My Omnia 7 keeps loosing it's 3G connection. To restore it I have to restart the phone. T-Mobile say that this happens from time to time, but it's happening every day now. It's annoying as it stops my push email from being up to date, and of course prevents the use of any internet based services until the phone is restarted.
Has anyone else noticed their phone has switching to GSM?
Had mine for 6 days.Been fine up until today,then I had the same problem.Only the once so far.
Confirm loosing 3G
Confirm loosing 3G connection, and also have phone call failures.
Factory reset did not solve the problem.
Bring it back to shop
Blackstone is back now!
At first this was occasional with my phone, then more frequent, and it's all the time. If I want to use the Internet I have to restart the phone. My house is covered by full HSPA, but the only way to get it is to take the battery out while the phone is switched on. I can sometimes get 3G by a simple restart, which I lasts about 40 minutes.
I like the phone, so I'm going to hold out for a software update. All it needs to do is check available networks and I think that, if this is a wide spread issue, Samsung/Microsoft will fix it. Hope so.
Please post here if you have this issue too.
I have also been having this issue... sometimes it doesnt come back straight away when i restart it but after about 10mins its back.
When I activated it with orange I was told to expect a few txt msg's that would need deleting and the phone restarting... I only got 1 msg, maybe this has something to do with it, maybe the phone hasnt been sent enough updates.
I also have this issue and have done for weeks. Orange couldn't solve it either.
It only happens overnight at home. I either need to reset the phone / rescan available networks or turn flight mode off and on again for the connection to restore.
I was thinking it may be an issue with t-mobile since it only happens at my home where orange signal is poor and i roam over to t-mobile.
If i stay in an area with good Orange signal i don't get the problem.
Good to know i'm not the only one with this problem. It's very annoying!
Hi y'all.
I had the same problem: 3G was lost every time. I was fed up restarting the phone every time, so I looked for another way to get 3G back. I found out that disabling and enabling SIM security (phone > setttings) got me 3G again... for a short while.
But: after disabling SIM security permanently, 3G kept on going (in fact for over a week now).
I think that changing the PIN to some other number, might cause this. I haven't yet tried changing it to the default PIN again, to see if using that for SIM security solves it. For the moment I'm too happy it works again.
I have suffered from poor reception issues ever since I got my Omnia 7.
It seems like the reception comes and goes. I will receive e-mails, which proves that the phone has been connected, but as soon as I try to use data myself, by visiting a web page or refreshing an app like facebook, the reception disappears and the "no reception" symbol drops down from the status bar.
Also, often when I try to send an SMS, it will appear to have been sent, yet 10 minutes later I will receive a "Can't send...try again" message. Once I have received this, the SMS will never successfully send. However, in the meantime I can receive SMS messages, which shows that the phone has been getting a signal.
This is SO frustrating and is ruining my experience with the phone.
I have posted requests on the Microsoft Answers forum and the only suggestions have been to reset the phone or turn WiFi off. Neither of these have had any effect. I have never enabled SIM lock.
I have heard that there is a firmware update due soon which includes a new radio stack. I am desperately hoping that this will improve the situation, as at the moment I cannot rely on my Omnia 7 as my only phone.
Alex.
Hi Loco,
You are right in saying that social answers doesn't really help much .
Luckily there IS a new firmware from a couple of days ago! Check out the Omnia 7 Dev section. There are only a few posts.
And here is also a good link for you. You are right to assume that it comes with a new radio stack which improves on performance.

Finally found a thread on this... I have been having a similar problem since I got my phone from Optus here in Australia. I took it back and they replaced it for me but the new phone is exactly the same. I don't lose the 3G icon but anything data related just ceases from loading. Right now I'm trying to refresh the Facebook app and it just comes up with 'Unable to connect', even though I have full 3G reception.
I flashed it to the newer leaked firmware and it hasn't changed anything, problem still persists unfortunately. This is a major problem that isn't getting enough attention! It seems quite widespread and Omnia 7 specific.
Had similar problems, but after I changed my provider ( O2-Germany), 3G is stable.
For the people having this problem, have you tried setting the phone to prefer 3g? Details of how to do this are here http://forum.xda-developers.com/showthread.php?t=915813

Same here man. On Optus and my reception sucks with this device. What the hell is samsung doing? FIX IT!
I have been having this problem with my Omnia 7. The frustrating thing is this is a replacement phone I had for an LG which I had replaced THREE TIMES due to random resets. So now I have a phone that I have to turn off and on EVERY MORNING in order for the data connection to start working again. Needless to say I am very frustrated. I am on Orange in the UK. I suspect it could be related to when being an a poor reception area and it tries to switch to tmobile. I am going to try turning roaming off. Please, if anyone finds a solution to this let me know.
Thanks

My problem got worse with the Mango update. I'm now on my 2nd handset after having a replacement from Orange warranty. This one still loses it's connection but much less frequently.
TBH i don't think it will ever get fixed. I started an MS Answers thread months ago and lots of people had the same problem but we never got a response from MS.
Conisdering the age of the model now I doubt Samsung care, well they didn't seem to care a year ago so they won't now... For this reason I will not buy another Samsung phone. It's infuriating.
Looks like I am stuck with it until December then when I can upgrade to a Nokia lumia. A long wait :-(
i have this issue, too.. but for me i only have to set airplane mode on and off. sometimes i deactivate data connection, go to a random website, get the 'no connection' error, then activate data connection back and it works.
however, after installing the latest drivers & firmware, i get this issue A LOT less frequent. like once in 2-3 days.
i hope ms or samsung will fix this because it can get really annoying. especially when you need eg. a quick google-search..
Just flicking the flight mode wouldn't be so bad but that doesn't work for me, I have to restart the phone each time. I love WP7 but this and the other problems with the LG is driving me nuts. Almost wondering whether I should have just followed the crowd and gone for an iPhone.

Same as me - Flicking flight mode on-off doesn't solve it, needs a soft-reset.
Like I say, there are quite a few with Omnias on Orange with this problem.
I'm in the same boat, I've had this for months now so I guess I'll just deal with it until I can upgrade the start of April and get a Lumia (hopefully the EU 900/910 will be here by then!). There is no way on this earth Samsung are getting any more of my money. Nokia seem fully commited so they can take my cash next time!
I have the same problem with the data stopping working on o2 in the UK. But I also sometimes cant receive calls even though the phone has service, then there are the times where it site there going GPRS/3G/3G+/No Service and you cant do anything with it apart from pull the battery.

Losing mobile network

I have a stock t-mobile s7 edge device. It's losing the mobile network. I've noticed it a couple of months ago - it happened a few times but recently the problem is getting worse. It already happened 3 times this week.
Seems like completely random. Sometimes I notice it after I go somewhere with weak signal or no signal at all. Sometimes when I get back to an area with good signal it reconnects and sometimes it doesn't. Sometimes it shows the bars and says it's connected to t-mobile but 4g doesn't show up at all. So you can call but no internet. Sometimes no signal at all.
When it happens the only way to connect is to reboot the phone. Nothing else helps. If you try to connect to network manually - it can find t-mobile but unable to connect. just spins. Changing from lte to 3g or 2g also doesn't work.
I even tried to create a new APN - same thing.
Please heeeeelp...........
Last time this happened to me on another device, it was the sim card that had a problem. Have you tried with another SIM card?
No, but I don't believe it's a sim card related problem. Wife's phone has the same problem although less frequently. But she also travels less.
It looks like a configuration / firmware or maybe hardware issue to me.
I'm experiencing the same issue. It seems to happen when the phone loses signal completely like when deep inside a building. Then it won't reconnect to data or the network by itself.
From the first moment when I got my edge back in April I noticed that the radio performance was weaker than other phones. Then I got the Note 7 and same issue again. Then back to an s7 edge and the problem seems to be worse on this one specially after the latest software update.

My wife (s7) and me (s7 edge), as well as a co-worker (s7) are having this same issue.
Before it was happening occasionally, but after the last update its happening WAY more often.
Wiping cache seems to help with frequency, but still did not eliminate the problem. Hopefully it gets fixed with an update. I'm not sure how much longer I'll be able to put up with it.
Edit: I forgot to add a "simple" fix I've found that works almost all the time is to turn off mobile data, turn on airplane mode, turn off airplane mode, wait for signal, then turn on mobile data. Those steps in that exact order work for me most of the time.
So I've been having the same issues as everyone stated. The only fix is to reboot the phone, but who wants to that every time. I even changed the sim card!! I wish T-Mobile would get out of their feelings and start selling more flagship phones.
I have made the decision to jump to LG V20. I hope this issue doesn't exist with the LG.
I've just got my s7 edge and I'm sort of having same problem at home got 2 bars and sometimes goes to 4 bars but also wen I called someone the line was crackling but person said could her me fine so done a wiped cache and think it's sorted it now for the time being
(Edit ~ it's done it again could hardly hear person I was talking to)

Sim Card Randomly Dropping?

Just picked up one of these phones. Really like it so far! One issue I've noticed though, after a few days of ownership, it's randomly dropping/not detecting the sim card? It's happened at least twice where I've left it to charge over night and woke up to the no sim icon, and yesterday at some point while I was watching YouTube videos in full screen (in my hands, off charger, no notice of the drop either whenever it actually occurred). Quickly popping the sim tray out and in resolves the issue. At first I thought it was because I was using a manually cut sim card, so I've since replaced the sim but the problem persists.
Anyone else have this issue? Should I have the device exchanged?
Thanks
First the phone froze and after restart dropped sim
I just had the same issue occur just now. The phone had frozen for over an hour before I did a forced reset and now when it started back it shows no SIMCARD and no connectivity. I am like you, I really like this phone but hopefully this isn't a permanent issue.
Watched it happen just now. Goes from bars to no sim icon without error or notice. Resetting the network settings, resetting the phone, and powering it off/on won't fix it. Literally have to pop the sim in and out and its recognized right away.
I lost sim recognition after I flashed to LOS 11/30 and no matter what I tried, phone would not recognize the sim. Once I flashed back to stock, it came back. Hopefully this was due to the rom and the problem won't come back.
I am not sure if I lose the SIM, but I will say that when I am driving around with Android Auto, I constantly see the cell signal go from LTE to no signal every couple minutes...

Had same issues when I flashed back to stock I actually have better signal than when I got it out of the box.... Almost as if the software wasn't installed correctly or something
Same here I'm on the stock room. I'm wondering if it is an app I downloaded. Any idea how to wipe cashe not the apps but system.
This is happening at least twice a day now. It seems to be software related. Power off and on without taking out sim fixes it.
