[Q] Cell network disconnect - Legend General

Hi everyone. I have a problem with my Legend that's been bugging me for a while, but I never got around to post about it. This is the deal: my Legend often drops the connection to the cell network, meaning I lose BOTH call and data capability. At first I used to reboot the phone, which fixed it, then I found out that turning airplane mode on and off would do the trick. Still, it gets old really fast...
I've searched the forum for similar issues but only found some posts about data connectivity loss / poor reception. In my case I don't have complaints about reception, and the problem isn't restricted to data.
The problem appears both in stock Froyo, which I used since it came out, and Cyanogenmod 9, which I installed last week after finally getting around to rooting the thing.
Any clues as to what the problem is, and better yet, whether there's a fix?
Thanks!

[Q] my G2 loses service, restart brings it back

hey everyone
so my G2, which I absolutely love, has been having a problem lately. in the first week it happened maybe once and i didn't think much of it, but since Friday it's happened like 8 times now. I'll be sitting there with my G2 and all the sudden I have no service whatsoever. Just an x on the signal strength indicator. 1 or 2 times it has come back after a minute or two, but the other times I had to turn the phone off and back on. the weird part is I'm not moving at all, totally sitting still, but when it comes back on I have FULL bars with HSPA+. so it's not like I walked into an area that didn't get good reception.
any idea what's going on? i looked around but didn't see other people having this issue. any ideas?
thanks
alright well at least i'm not alone. i remember that rumored OTA update was supposed to have some radio bugfixes. maybe when the real OTA update comes it will have something to fix this. i hope so.
I have been trying to diagnose this issue on my phone too.
By any chance, do either of you have your BT on at the time?
Happens to mine as described and I have never turned on bluetooth. However this would also happen to my G1 so I think its a network thing personally.
Yeah, it definitely is. I have 2 areas that it happens in, both are while I am in my car and I have BT on in my car. When I ran it without BT, did not happen.
I have found that when I am in those area's, turning off 3G stops it entirely, even with BT on, so when in my car, I set edge and still use my BT and problem is gone.
I hope this is temporary and an OTA can fix the handoff from 3G to Edge and back better so that I can stop this, but this works well enough.
Mine has done that also, maybe once a week for the past 3 weeks.
Judging by the other problems you can have Id say this one isnt that bad. Especially if it only happens once a week haha. This is the only problem I have with my phone.
no bluetooth...
no no bluetooth on, i never do actually... but also my G1 never did this, which makes me think it's NOT a network thing, but I don't know.
also I'm sure this is just coincidence but it almost always happens when my girlfriend is nearby with her T-Mobile Blackberry Curve. i know it wouldn't make any sense, but she's sitting there on the same network with full service and all the sudden my G2 loses service completely, right next to her... although it's not always while she's there, but like the majority of the times she's been there.
I just started another post to check on something, I have widgets that show me when I am connected to 3G and when I am connected to H. I have noticed that the phone is activity managing that connection. In other word, it is in 3G until data is transfered then it goes to H. I wonder if when we are in areas of "questionable" HSDPA signal if this hand off is causing the problems.
I have seen a lot of op's say that there problems come right after some data activity?
Just a guess a this point
i saw someone mention in another post that it happens after/during a text message alot of times. i haven't noticed that myself, but that's something to think about too.

What I've heard is that the phone will stay in 3G mode until you begin using data in order to save battery life. Makes sense to me.

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.

[Q] 3G/ data connection turns off spontaneously

I have a very annoying problem:
For some reason the data connection on my Legend turns off spontaneaously. Only way to turn it on again is by turning on/off flightmode or data connection.
Because of this I'm missing out on emails, facebook updates and whatsapp messages. Very, very annoying.
It should just work in my opinion -i.e. have a stable, permanent data connection . Btw, I have tried with my sim in another phone and then the connection is stable. So I am sure it is hardware/software related.
Anyone? Thanks!
I get the same issue if I'm out of range for extended periods of time. Almost as if the Legend forgets to search for signal again. A reboot fixes it in the short term
3G/ data connection turns off spontaneously
I have a same issue on my Legend, hoping that someone will come up with a fix...!
I also had this issues with CM-6.1 after 3 month without any problems.
Today i updated to CM-7.0-RC4 and the problem is gone and hopefully don't come back (Was gone before i updated the radio)
anyone has some useful idea in this topic? i am also ccping with this problem. syncing worked for 4 months and but since then it just disconnect from mobile data network and i have to force it to connect again. I have stock 2.2 rom anyway.
have any of you tried factory reset to solve this problem? it is a bug, i think and man, we sometimes miss important things.

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)

Network issues (Data)

I'm experiencing issues with the network, I often have to go to plane mode then disable it to get my connection back (I always have the 4G logo on screen, but internet pages won't load, facebook either, well everything) I'm seeing posts about the WiFi issue, but nothing about this, am I the only one experiencing this ? It occurs every 5 minutes or so, pretty annoying when you are in the middle of a youtube video or so..)
Thank you in advance !
I could say I have the same issue.
I realize this post is 2 months old but I also have this exact same problem. Data on WiFi works perfectly fine. On actual mobile data though it works great for a long period of time (hours - days) then suddenly gets horrible. Disabling and re-enabling data seems to fix it most of the time, then it works great again for a good while.
Would this indicate a software glitch? I've been wondering if I should try some custom ROMs. Or would it be a problem with the physical antenna or data module in the phone?
I'm on the verge of sending it back under warranty but if it's software maybe something else can be done to fix.
