potential signal problem - Verizon Samsung Galaxy S III

Hey everyone, i'm a new coming from the OG razr and while i heard the radio on the s3 isn't as good as the razr i think my phone might have a problem. It seems to get stuck on 1x a lot and the only way to get back to 4g is to restart the phone. my phone is rooted but stock rom. Is this a common problem? Also under under APN LTE verizon internet is checked not EHRPD. Is this correct?

Its not normal. Take it back before your 14 day period and they'll give you a brand new one for it. If you wait then you'll just get a refurb.

is unrooting as easy as rooting? I'm hoping theres a script or program that can unroot as I'm not the most tech savvy. I'm guessing if i'm bringing it back i'll need to unroot.

You know how to use Odin? Look at section two, "how to get back to stock from any rom."

dont know how to use odin but the instructions seems easy enough. Just got off the phone with CS and they tell me its most likely the sim card and not the phone and to go to a store to replace it. Is it true that the sim card actually controls the signal?

Yeah it's true, put simply. You can see if it's the sim. But like I said, if you try to get a replacement after your return period, then you'll just get a refurb. So be quick on the draw if the sim card doesn't fix it.

My s3 isn't having that bad of issues but still some bad data reception. Is Samsung going to do any updates or is it just going to be like this permanently

S3s are known to have a number of data issues. Call technical support and try their ideas. When you can rule everything else out, then you know it's your phone. Basically, if a new sim or a factory reset doesn't fix it, you need a new phone.

I took my phone in the store yesterday and they told me flat out that I sim card won't do anything for your signal. I'm not discounting what you're saying, just telling you guys what they told me.
My signal is garbage at home AND at work. I use wifi at home to play with the phone but actual 3G signal is bad. I am lucky to get 2 bars but its generally 1 with speed tests of about 80kbps.
I don't have WIFI at work, and get no signal at all.
I still have a week to return the phone but I'd like to keep it if I can get a better signal.
I am still within my 14 day, maybe 5 days left

Are you new to VZW or have all of your phones had the same problem?
With the thought of you possibly leaving VZW, you would think the store would have tried a new sim card, if only to pacify you. Or they might have offered to switch out the device.

I have been with Verizon for years. My Droid X didn't have the best signal but it was much better than this.
One problem is, the store is located in a 4G area, it works great there but it doesn't where I live, nor where I work (which is a decent sized city)

It sounds like you have a bad phone. I'd be pushing for a new one before your worry-free period is up.

Okay, I reset my phone this morning and surprisingly, the signal is much better.
I went from 80-100kbps to about 500-600 kbps. Does that even make sense? The phone is only a week old
Now, perhaps I'm getting too hopeful here and the wind is blowing the right way today or something.
Yesterday I checked my signal with 'Open Signal' (I'd love to know of a good tower location app), and my signal was about 20-23%, right now its at 32-37%. I know that isn't a great jump but in the scheme of things, it is. I'm also at -97dBm, I think yesterday and the day before was over 100
I will note however that I'm still at 2 bars of 3G
I think its just chance , but I'll keep an eye on it.

Couple of weeks ago I also contacted VZW about bad signal/slow data speeds with my phone. They also told me a SIM would be the first fix to try. I had them send me one, for free 2nd day.
Before I swapped it out.. I rebooted my phone and put it in a certain spot and observed signal strength. In my house it ranges from -109 to -113. The data speeds, when the test would even finish, were abysmal. Ran 3 tests and in general they were about 500Kb/s down and anywhere from 0 to 300Kb/s Up. And that was on LTE!
Now without wiping my phone or anything I installed the new SIM and called VZW to activate as their website was bombing. Finally got the thing activated then put my phone back in the same exact spot to observe any changes. While signal strength did not get any better my data speeds increased a whole lot! In the same spot I was getting 5 Mb/s Down and 3 Mb/s Up on average.
Ive also noticed a decrease in LTE drops to 3G and 1X like I was getting before.
So while Ill say that it would seem to be impossible for a SIM to make your signal better, it just may help with your connection.

Thanks for that, I'm going to go up there in awhile and at least swap the card

Well this is my side of the story I had the Galaxy Nexus before sometimes in New York I am in spots where I dont have 4G what is weaird when I go into someones house which i've been many times I only get 3G and then when I go outside I get LTE anyways at the same spot I get 1-2 3G bars and my friend gets 3 bars on iPhone 4S but when doing speed test on both it seems about the same.
Also I am running CM10 and when I was on stock I could tell the signal was a little bit better , you guys think it would be worth a try to swap out sim card as well? how do I make them give me a swap for free?

[Q] G2X 4G Problems

I've had this phone since release and have loved it. I have only one issue with it. I'll be trying to use my internet on the phone and it will show the upload arrow but the download will never do anything. I have full signal so this is not the problem. This happends a lot and in the middle of browsing it will do it... It will load a page and I'll click a link and it wont load and then it will work again after awhile. Does anyone else have this problem? Does anyone know a fix or the reason its doing this. Also I have full 4G coverage where I am.
It happens to me a lot too! Its very inconvenient and I know its not the area where I reside because I also have a g2 on my spare line and the g2s data works perfectly fine when the g2xs is stalling. :/
Sent from my LG-P999 using XDA App
Did you get yours at release? If so it may just be the first batch or something...
Could be lots of things. Have you activated and are using the SIM that came with the phone. Supposedly the G2x uses a new SIM format.
What OS are you running? Are you on WiFi? 2G, 3G, 4G? Where does this occur?
I surf my with my phone a lot and I don't get that intermittent data problem you are describing. I am running the latest CM7 (#70) and in a 3G area with average signal quality.
I'm using the SIM that came with the phone and this is only on 4G I reverted back to stock ROM unrooted and still has the problem
I've never rooted my phone. I've actually swapped the sim twice already thinking it was the problem. Hard reset has been done. I've pretty much tried every trick in the book and the problem still persists. Its my 2nd replacement(1st one had the same issue)

P.s I got the first one at release then had it exchanged(buyers remorse period) for a new one towards the end of may so I doubt the 2nd one was from the first batch.

Like Player said, could be alot of things. For a sim, the G2x does not require a brand new sim, but it does require a newer sim. If your sim is older than 18 months, put in the one that came with the phone. Last years TMOBILE sim will work with the G2x.
Also, data plan. Didn't happen to me, but did happen to my son, the plan was not enabled for 4g Android. He got signal, rarely 4g...but did get 2g.3g. Walked back in the store..asked what was up...they checked...1 mouse click and finished. Funny thing was, he bought the phone from them, earlier in the day. You would have thought they would have covered that.

Your sons phone was showing 3g? Hmm... I thought on tmo 4g was a fast version of 3g and that the g2x only showed 2g or 4g. I am probably misunderstanding something.
So I went to T-Mobile just now and they gave me a new SIM and it fixed all the problems so if anyone else is having trouble try getting a new SIM first....its free

So frustrated, about to return One X but seeking advice

All,
I have had the One X for just over a week now. Three times, I have had to hard reset the phone because it stops receiving / making calls, and data stops.
I tried searching the forums but it seems like issues are all over the board and couldn't really find something that was exactly my issue. If there is one, I apologize for the duplicate post.
Regardless, when the phone is in this state, it appears like everything is working. It shows I have great signal, the little 4G icon is there, indicating that everything is working.
Anyone else have this problem or could I possibly just have a bad unit? AT&T already swapped out the SIM card thinking that might fix it, but no luck.

I think you should swap out the phone as bad before returning it if that's the only issue you're having. mine seems flawless in that regard. I haven't missed or dropped a single call.

I don't recall ever having that problem. Mine was pretty random too, in fact it got so bad yesterday that I missed several important calls.
If I would restart the phone, I would get all my missed text messages and the voicemail (google voice) would tell me I have messages waiting..
Very frustrating.

I thought that might be my problem too, but where I could stand in one place and have the problem, restart the phone, and then not have the problem -- that leads me to believe there was something wrong with the phone.

Nope the wife's inspire stayed on hspa
My X started out ok, but these last couple of days I have NO signal anywhere. Also SMS/MMS is barely working. (and when it does, people are getting multiples) And its dropping pretty much every single call.
I just called my corp store, they have plenty in stock. I'm going to go exchange it. Should I ask for a new SIM also?
And my screen is perfect, here's hoping I get another good one...

However, AT&T's LTE phones are notorious for connection problems on non-LTE market. These LTE phones use a new APN called pta. I just had the same problem while traveling through PA yesterday. Lost data connections many times and had to reboot the phone at the end of the day to regain data connection of any kind.
So, it is AT&T's service and also the phone firmware that can't properly handle the fact that it can't receive any LTE signal in certain areas.

return it and get another phone, besides the One X, it's all hype anyway. The HTC vivid is a much more solid phone.
I had almost the same issue. My device was on wifi and would at random times just stop pulling data. Or at time just not make calls. I tried trouble shooting it but I was basically told since I didn't have it long I should get it replaced. I replaced it and the new device is perfect. I have not once had that issue again.

Who said I'm going to reture it. OneX, regardless all its problems is still way better than any alternatives AT&T have. There is no such thing as problem free Android phones. I've being many of them. They all have problems one way or another. Vivid with its ancient S3 CPU and SD screen just plain sucked. My SGS2 can kick its butt.
For me the form factor of One X, LTE speed, S4 processor and HD screen are the main things I pick One X over any other phones available on AT&T. These software bugs will be corrected overtime.
I just came back from my store. They had plenty in stock but said when that runs out, they have no idea when they will see anymore.
I have a brand new 1X, and a new SIM card. Hopefully this one works.
I stopped by a vzw store to look at the gnex and my hox side by side. I've decided to keep the HOX. Screen on the gnex was way too bright and I ran quadrant side by side on both phones. The hox blew the gnex out of the water.

Bought mine yesterday and this same issue happened to me today. Had full reception on 4G but could not send a text or place a call. Happened twice today, and I dont know if I want to return it ASAP or if its software related and may be fixed.
I had that problem 3 days after buying the phone. Data, calls, texts..tons of problems. Phone was unusable half the time. I went and exchanged it for another one. I am now at 6 days with the new phone. No problems. I hope it lasts.

Verizon GS3 stuck on 3g

Second day owning this device and love it so far, but day two has been rough. I am stuck on 3g. All of a sudden today my lte switched and will not go back. Iv'e rebooted, toggled airplane mode and data. Even pulled the sim. I live in a strong 4g area so that is not the problem. My buddy has a nexus and his is fine. I also have had great reception in areas I have always had problems, so not a reception issue. I called verizon and was told it is a know issue that is normally solved with a reboot. She said an update was scheduled for early September to fix the issue. The point of this thread is to find out if anyone else has had this problem, or found a solution.
Edit: After countless toggling I got it back to 4g, but it won't connect to the network. So my thought is that the sim card is trashed. Going to get a new sim card first thing in the morning.

Unfortunately I am also finding myself stuck in 3g. I have pulled the battery, installed a new ROM. Still working on it, not thrilled. Prior to 4g disappearing, it showed 4g, however I was unable to connect over it. I hope this isn't a hardware issue.

Did this work?
Just FYI, I have the SCH-i535 and am noticing similar behavior. I had a Samsung Droid Charge before the SGS3, and it stayed locked to 4G LTE in the same exact areas of my home. If my Charge did happen to drop 4G, it would always come back. But not with my SCH-i535. Once 4G drops it stays on 3G until I reboot the phone. So far, this is my only complaint about this phone.
It is very random for me. Im certain its a **** sim card. Right now its fine, but at any time it may get stuck on 3g. Also while at work the first couple of days it would hold a decent 3g signal, now its primarily on 1x. Once i replace the sim card I am hopeful for it to be fine.

I thought Verizon said that this was a known issue? I'm just curious as to why you would disagree. But if a new SIM does happen to fix the problem, please let us know.
Just a heads up! I have the same issue, but I can't get 4g back at all, which I thought stemmed from flashing CM9, but this thread is making me wonder now! I spent an hour on the phone with Verizon technical support and they said you will get a popup if the sim is the issue. They told me its the phone and they are sending me a new one. FYI you can try this code. *2767*3855# in the dialer to factory reset the phone ( can do the same in recovery ofcourse), but you HAVE to be running STOCK UNROOTED! Some people have had luck with this "resetting" the radio I guess. If this doesnt work, might as well call them and get a new phone coming. TRUST ME, I believe I did everything I could think of before calling them, except taking the phone apart and pulling a new radio out of my ass!! Lol
I'd just return the phone and get a new one if possible.
They did tell me it was known issue. Its just weird how random it is. I am hopeful it is either the sim card of a software issue. I hope it is not a hardware issue. I would rather not have my phone replaced as I just put a new screen protector on. Also to those getting a replacement, is it brand new or a certified like new device?

I did read in another forum that the replacement phones are coming out with a baseband update. I'm guessing that we will probably need to exchange our phones...or be patient for the OTA. Hopefully it won't be too much longer. Incidentally, I just did a factory reset and 4G now appears to be working. Time will tell...

I also flashed CM9, and I am fairly certain this was the cause of my problems. Nothing I did would make 4G work again.
Other 4G VZW devices seemed to work fine at the same time(I have an ipad3 for work, POS).
I didn't mess with it for a couple of hours while running errands, then all of the sudden it was working again. Been fine ever since as far as I can tell. It would be nice to know what exactly is causing this, but for now I'd caution against messing with cm9 .

AT&T G2 LTE signal problem?

Hey all,
I recently picked up a LG G2 (second hand)
and I believe I have some issues with the phone not picking up LTE so easily.
Before this, I had Iphone 5, nexus 4, G Pro, Gnote2, etc... and they all picked up LTE just fine at my home
However, G2 rarely picks up LTE signal and it is mostly on HSPA+ (4G Icon) I believe.
I took it into AT&T store to see if I could get a new sim card but when I got there, the phone picked up LTE no problem.........
Looks like many Sprint users are experiencing same issue.. is there a fix for this??
*The phone is currently on stock / non-rooted 4.4.2
Thank you in advance!
I'm in the same boat as you, my data will work for a good 30+ min and then all of sudden no network for 30 seconds or so. I've also been unable to connect to a lte signal I've only been able to use hspa, searching the threads on here have been hit and miss with a lot of vague answers but nothing clear cut if anyone's dealt with this and has a clear fix it would be appreciated.

A little update to this, yesterday I went to AT&T to see if I could maybe clear this up with a new SIM card and while waiting I checked out the two G2s they had there, these two display phones were literally 10 ft apart and one had lte while the other one was stuck on 4g only. I think this is looking more like a hardware issue now after checking out both store phones on display, I'm going in today to swap out my handset to see if this will solve it.

Here's another update for those with lte or signal loss issues, after trying everything I could find on these forums the only answer was a warranty swap out, as soon as I put my SIM card into the warranty phone let showed up and after half a day I haven't experienced no random signal loss at all.

Interesting...
This is interesting. Currently running CM11 latest nightly and I thought it was due to CM codebase. It looks like non-CM related?
Please keep the details coming. When I have time, I will flash a stock ROM to see what happens. But at this point, it looks scary that maybe hardware problems might be there.
For comparison, 2 iPhones literally next to G2 had 3 bars with LTE while my G2 had no network.

Before returning my phone for a replacement i was fully rooted on gardys kit kat rom with recovery, i had read that supposedly rooting or flashing was apparently breaking lte so i went back to the stock jellybean rom only to discover the issue still there, i then fully updated to the over the air kit kat update which also did not solve the issue. It really does look like theres a issue with the phone itself.

Oh wow. Thanks for your reply.
So i have tried working on this and so far no good.
LTE picks up good when i walk into an att store and that is causing difficulty with store workers..
I get stable, steady connection with hspa+ but rarely pick up LTE..
What is the process of getting a replacement? Its way over 15,30 day period for me..

For me lte did not work at all even in store, I can see where you might have a issue if they can't reproduce the issue but just be persistent and they should take care of it for you. As for warranty you have a year from your purchase date for a warranty claim through At&t, I went through a device support center which you might have depending on where you live otherwise you can send it in. You must revert back to a complete stock state or you will be more than likely denied.

Got it fixed after several attempts with new sim cards! Picks up Lte fine! Wootwoot
My fix
call att tech support make sure that the lg g2 imei matches your line/sim card
So I went through a bunch of phones in the past couple weeks, I have at&t service but my last phone was verizon droid maxx. Next I went to the AT&T store and he put my phone number under the new sim card for my AT&T LG G2 but the rep didn't ask me for the IMEI or look at the phone at all, he just got my line on the new sim and I left. I noticed the phone was going back and fourth to LTE but it was 4g (non LTE) about 70% of the time. I changed APN settings, I updated, nothing worked. Then I remembered a long time ago that if you go from android, blackberry, or iphone to another type of phone you would have to call att and make sure something was changed so I called att tech support and asked if they would put my IMEI under the new sim, the tech said yeah I should do that because currently my line doesn't show I have the g2 (make sure to call tech support because online it'll show you have a g2 and if you call costumer service usually they will see the g2 too) and after that i reset my phone and got LTE 100% of the time since then.

[Q] Maintaining 4G connection issues?

I just got my m8, and it's completely stock, not even rooted yet. I'm having trouble maintaining a 4G connection. Even when I'm in an area with a strong signal, my phone eventually falls back to 3G and then won't upgrade to 4G until I enter and exit airplane mode again.
Is this common? any ideas on how to fix it before I just bring it back?
Thanks!
[Edit]
I went to the verizon store and got a new SIM card, and that's resolved the issue, I get a good solid 4G connection on a consistent basis. Maybe the old one wasn't maintaining connection? not sure but it's fixed now.
Thanks!
That's weird. Maybe you have a defective phone. Go get it exchanged.

I just got my M8 too and my 4G seems to be about the same as my last phone
...maybe a little bit better

Have seen this personally on 3 devices (all purchased from different locations). 2 employees and 1 myself. Its like it takes longer to get a 4G signal. I cant figure it out, but have learned to deal with it. It eventually gets a 4G lock, just not as soon as I would like. I have noticed that Insert Coin gets a 4G signal faster than the official vzw based ROMs though. Not sure if placebo though as my only ways of testing is watching the phone to see when it gets a 4G signal, when I know its in a strong 4G zone.
I went and got a new sim card and surprisingly enough that seems to have solved the issue. Maybe there just wasn't a good connection with the old one? Not sure, but problem solved.
Thanks!

I had similar issues when I got mine. I switched from my S4 to the M8 and had to get a new Nano SIM card to fit the M8. It had issues with connecting to any data connection but I was able to fix it by taking out the SIM and then pushing it back in but not too firmly. I suppose it was the positioning of the SIM with the tray.
