No signal or data

I'm not skyraider Zeus preview and have no no issues till last night. Now all of a sudden since last night I have not been able to get 1x, 3g anything and signal drops. Have multiple lines on verizon and the rest of the phones are fine. Really don't want to change roms but will if I have to.

Have you tried to just reload the rom on top of what you have now?
Have you tried to restore a backup?

Okay I just restored a backup of liquid gingersense and same problem... Starting to get a bit scared.

Alright flashed the brand new GB radio from "someplace." Still have same problem. Sometimes I have full bars but no 3g and can't get calls tried to test and calls don't go through so my phone is kinda pointless... I'm really panicking I need this thing...

When you installed the new radio did you also install the LTE radio?

Honestly no clue how would I be able to tell? I've installed nearly every radio and never has two separate radio files.

There are not two separate radios to install. If you downloaded MR3, it will work if you're on a GB Rom. If you're on a froyo Rom then you need a froyo radio.
Also check to make sure your battery door is completely attached. Your antennas are in the door and it must be attached.

Were you running a leaked radio when you had this problem first off?

I was running the OTA MR2 radio since release never had any problems then last night out of nowhere it just happened. Have been scrambling ever since.

Went back to MR2 radio now since I know it's not a radio issue. Battery door is completely sealed. Checked to see if the metal was bent in any way and it's not.
EDIT: Every time I reboot it gains bars back for a bit but no 3g. I've tried calling during this period to no avail. Then it looses bars with just an x over them. The one thing I am thinking is there any possibility that the sim just died...

Did you check your mobile network settings? Are you on LTE only mode possibly?

As goofy as it sounds, when I first rooted my TB awhile back I completely lost signal then was able to pick up 1x and that was it. I did a factory reset on the device (as instructed by VZW), and it actually worked. Nothing else had been done to the device besides a root, no one else could figure out what exactly went wrong, but the wipe restored it back to "factory" root and it worked perfectly.

No LTE/CDMA. I have done like 30 factory resets lol. Called Verizon to make sure there was no outage. I'm getting a new device (Not refurbished shockingly) over-nighted. The big bummer is having to reroot and such, but hey the guy was nice about it and everthing so no complaints. I can live without it for one day. Thanks for all your help guys!

Anybody still having data issues?

I've been using my Rogers HOX ever since it came out but always had random data drops. Tried all kinds of radios (with or without RIL) and all kinds of roms and the issue is still there. Losing data is not the biggest issue but it also drops the battery real quick because it keeps trying to connect.
Anybody ever find a solution to this?

I'm using the HOX on Straight Talk and lately I have noticed that when I have WiFi on for a while, assuming it stays connected, I lose mobile data. The only thing that bring it back is toggling airplane mode or rebooting the phone.
I am on Jellybean, and I am not sure if the issue was present in the stock ROM's.

Yep still having the same problem on AT&T with every combination of Kernel/ROM/Radio you can think of. I can also say that it isn't a "rooted only" problem because a coworker is having the same issues on 100% stock software. There's always that ONE THING that keeps my phone experiences from being perfect. Grrrrrrrr........

My rooted One X is doing the same thing. I can't wait for the Galaxy Note 2 to come out. HTC just can't quite seem to figure it out.

Stock 2.20 on Straight Talk. Have to toggle Airplane occasionally. Especially in North Little Rock. ::shrugs::

OP, have you restored your stock setup to see if the issue persists? Basic question, but for the sake of a starting point.

After so long, finaly found the problem. I don't know if it'll be the same for everyone but the problem was Swiftkey keyboard. The moment I uninstalled it, the problem did not reoccur.

I have the same problem and I can assure you its not the phone, I have used many android phones, iPhones, and regular phones on rogers 3G network and they all have the data drops in general like dropping to 1 bar and no service once and while.
You might want to switch your network to wcdma/gsm instead of wcdma/gsm/LTE. If you dont have the correct APN for the rogers lte network it will keep searching for the lte nrtwork causing the data drop. As soon as I turned my lte toggle off the network stopped dropping randomly though I still get those random data drops caused by the network

We had this issue with the rezound, it actually occurred because you flashed different radios.
You had to flash a ruu or a modified one without the system image. See my SIG
So try flashing a ruu, this doesn't explain someone with a stock phone having issues but I bet that's just tower issues
I don't have any of these issues

Tried all of the listed solutions and nothing worked. I know it's not the network because I don't have the problem with my Note II. Swiftkey was the issue for me, once removed, the issue never reoccurred.

Wow, you might be onto something here. I just installed SwiftKey last night and immediately started having issues. Data has been off-and-on with different versions of different ROMs, and never suspected that my issues may lie within an app that I was using. I was mucking about with radio ROMs and a million other settings, never realizing that SwiftKey was installed right around the time I started having issues on each ROM.
I'm going to jump back to CM10 this evening and see if this was my issue.
THANK YOU in advance! (Thanks button has been hit!) Nice work!

You gotta be sh***ing me! After all this time scouring xda and numerous other sites.starting my own tread it was SwiftKey all along? Wtf? I did a thousand different things. Nothing worked, took off Swiftkey, bam, flawless. I've got a T-mobile GS3 incase anyway was wondering, no, apparently it's not just with htc or AT&T/Rodgers. Weird though cuz my wife has a AT&T GS3 with Swiftkey and has no issues whatsoever... Did you dl your version from the playstore or from a 3rd party? Thanks a million for posting your solution. This was absolutely killing me. God do I hate this stock keyboard though...

[Q] Signal issues with my S3

So my and my girlfriend switched both from Droid X's back in September, with that said we never had any issue with signal at our house(all ways had full bars 3G). Soon as i came home with my S3 i noticed that both of our phones had poor signal strength 3G 1 bar or 1x. I called verizon tech support they had no idea what was going on and were wanting to replace my phone, saying my phone was the issue. However my Girlfriends S3 was having the same problem now i don't think that both phones are defective and the tech rep was wanted to replace my phone with w refurbished one which i just bought this one brand spanking new. So i was wondering am i the only one with signal issues? And my other questions are .... Is it hardware or a software (radio) issue? Will there be a fix / Update?

It's just Samsung doesn't have good radios.
There's suppose you be an vrlhd update that suppose to help with signal and data

So there is no hope to get a new radio update at all?

Theres a update coming soon that'll improve the signal issues with the S3. Its not JB update.

Good at least some hope for my S3.

I got the vrlhd radio and I don't think it really did anything. It might even have made my wifi at home slower! But maybe I'm just paranoid lol

I don't think the HD radio did anything to improve my already piss poor reception either.
Synergy r73, Trinity Alpha 7 thanks to the monkey

Yeah none of the radio updates have made any significant difference for me. At my house, my old Motorola phones always had full (4 bars) of 3G, and my bionic actually could pick up a bar or two or 4G every now and then.
My GSIII gets a bar or two of 3G at best, and my reception fluctuates between -100 and -80. I would've never gotten this phone had I known the reception would be this weak.
Everything else about the phone is good, but none of it matters when you can't really use it like a phone and have to depend on wifi, which is somehow also weaker than any other device I've ever used.

There's no two ways about it - Samsung radios suck @$s. I dumped a Galaxy Nexus earlier this year for this very issue and switched to a rockin' radio Moto razr maxx.
It may be hard to believe, but the s3 radio is actually better than the Nexus was. Fortunately for me I moved to an area with strong 4g almost everywhere, hence I can enjoy the rest of the s3. If I hadn't moved, however, there is no way I would have given up the moto.
It would be nice to see Samsung get their act together. Oh, and don't expect a software update to fix anything.....it won't.

If you are referring to the HD verison it's not making much difference for most. Or do you have information on something else?

I can barely if at all use my phone at my house or my neighbors across the alley..I have to be on WiFi..I have tried every radio including the leaked HD radio..all horrible..part of me really hoped Samsung would somehow fix this seeing as how they have acknowledged that it is an issue...is there any other way they are going to be able to fix it? Meaning is it just the radio and all they can do is keep trying? Or is there stuff they can fix more on the software side..maybe the RIL (radio layer interface) which as I understand is kind if the middle man software wise between the radio and the operating system..idk just sucks to have such an amazing and fast phone and to really be ready to get rid of it because it is that un usable..and don't get me going with touch wiz..I can't believe how sloe that makes this phone..aosp ROMs are easily 3 times as fast but then they have the data drop issues which are just starting to be fixed now by the RIL patch... ugh so much to think about..wish there was another phone out with a big developer community that was good unlike the galaxy nexus

Maybe the JB update will have better software side support? Or maybe you could take it to your Verizon store and see if it's an issue with your phone? Idk

Well I know its a known problem and I read somewhere that Samsung acknowledged the issue but either way I'm going to call for a replacement just to see if it makes a difference..just gotta think if what to say..cause I know if I just say I have signal issues they will say that smasung is working in an update to fix it..lots of people on all the forums have said that's what they were told when they called for signal issues

[Q] Reception issues?

Unlike some people I've always had pretty good reception on my S3 where I live near Chicago. I had been running "Jelly Beans Build 4" for several weeks with no problems (using K1 Modem and Stock Kernel). Then last week I updated to the new Beans build, Build 6 and installed the K3 Modem and RPM (running LeanKernel). Ever since doing that, my reception has gone from always around 4 bars to usually hovering around 1-2 (happens both when I'm at home, and at work in the city and has been pretty consistent). I tried going back to the K1 modems and it didn't change anything (ended up trying all the JB modems with no differing results). I've also tried flashing the stock kernel again. No matter what I do, my reception doesn't seem to change and I can't get it back to where it used to be. Is there anything else I can try? I'm about to flash back to another ROM to see if that changes anything. Any ideas would be great though. Thanks guys.

Maybe check to see if your prl version is up to date. Do this by going to settings about phone them status. Should be 15154. If that is good no modems work and previous roms are no success then maybe they are doing work on some towers in your area. That happened to a coworker of mine on sprint and once they were finished everything went back to normal maybe even better but it took about a week of him pulling out his hair. (he is bald now). hope this helps and good luck.

Thanks for the advice; yeah I checked, the PRL is up to date as well. And flashing back to another build didn't make any difference. So I'm beginning to think maybe you're right, maybe they are doing construction or something.

[Q] How/why are Sprint ported roms getting better data reception

I flashed the Goodness and the Wicked Sprint ports after hearing that they bump up dBm by -10 I was very sceptical thinking maybe it was just measuring incorrectly or differently giving scued numbers. While running Wicked yesterday I went to a restaurant and a local store were I struggle to get 3g and drop often. I had a bar of 4g ! and no drops I was going to restore a CWR nandroid of Beans7 to see if it was the Rom but I recently switched to TWRP and didn't have time to fool with it. Anyone know how this would be possible? I've flashed a lot of roms and never noticed any difference in dBm even though they were said to be tweaked.

Yep running the Verizon blk3 modem and rpm, for anyone who doesn't know Sprint modems will do nasty things to your phone never flash them (any modems other than Verizons for that matter). I went back to CWR so the next time I get back to the restaurant or the hardware store I'll restore back to Beans and get some screen shots for comparisson. I'd run some speed tests but they always end up being all over the place I don't think it would prove much. Post my shots once I get them, there is supposed to be a new Goodness rom out tonight so I know what I'll be doing later Flashhhh Aaaaahhhh God I love this phone
[Edit] screenshots first two Beans 7 second two Wicked Sensation port. Taken from exact same spot in the store, Wicked kept 2-3 bars of 4g through out the store Beans 7 never got 3g and dropped completely twice had to airplane to regain signal.

Noticed 10dB listed increase in signal on Wicked Sensations compared to CleanRom. Don't know if it's just the way the signal is reported or real boost!
