[Q] Reception Problems - AT&T Samsung Galaxy S II Skyrocket SGH-I727

okay guys so I just switched over from the Galaxy S to the S2, Skyrocket LTE
I had full reception at my house with the Captivate....Now, with the skyrocket I still have full reception....but with a catch
I'll have full service...then all of the sudden it will drop to 1 bar and be unable to send any texts. (Message not sent error). Then, like 45 seconds later it will turn back up to 5 bars and ill get texts.
the time that its off and on seems to be consistently repeating and switching back and forth between 45 second intervals. Also, sometimes ill get all my texts together (9 unread) out of nowhere with time stamps from 5-12 minutes ago.
I'm running STOCK everything:
Android version 2.3.5
Baseband: I727UCKJ2
Kernel version: 2.6.35.11
I wanna root my phone but I wanna make suree there isnt a problem with it.
I think its also important to note that this problem is ONLY in my house and around my house. not anywhere else.
Any ideas on what could be causing this, or any solutions? anyone else have the same problem?

I'd recommend reporting your thread via the upper right link to have this moved, you got it posted in the wrong phone section. I'd try to take a stab at helping ya but honestly it would just be a guess...

Thread moved from AT&T Galaxy S II forums to the Skyrocket Q&A forum...

anyone have any idea?

There have been some problems reported on the LTE network, but the biggest problem was/is.. people not being able to make calls when the network mode was set to lte auto. Depending on where you are, you might want to check the coverage map for your location... and call your carrier.

Thank you, do you have any links regarding the problems reported? I'm in LA, I dont think we have LTE here yet. Also the problems seem to happen only at my house, not even like 1 block down. I know I had full coverage here with no problems on my Captivate. It's just this phone, reception drops to 1 bar, then 5 .... like every 10 seconds, keeps going up and down, I gotta time when to send my texts so they go through lol.

I want to say lte is in testing for la. That could definitely cause issues if they are messing with the towers. The same thing happened to me while we were in Vegas...a few days later everything worked ...including LTE which Vegas previously did not have. Its also worth checking to make sure ATT has u on an LTE plan. Its been documented that if they have not done that it can cause some issues

the captivate is not a 4g or Lte phone...the phone is not trying to switch between 3g to 4g...i think thats the problem with your SII..trying to change from H+ to Lte without succes in an area doesnt have Lte

The only links that I have seen, are for rogers here in Canada.. don't know if that would be of any help to you? While my signal strength is all over the map, I have never had any problems making or receiving calls.

I went ahead and called. It seems the problem is, as everyone suspected, the phone trying to switch from H+ to LTE. the 4G logo seems to change from 4G to 4G (LTE) when it drops reception. Will rooting / roming help stop this? Are there any ways of turning off LTE until they get it fully working?
With regards to the quote above, I currently have Unlimited Data since i got grandfathered in. The guy at the ATT store told me I dont have to change my data plan and I'll keep my unlimited (so i did that). He gave me a new sim which he said "will help give you better reception". Will I still have issues because i dont have the new data plans? I want to keep my unlimited data.
**EDIT**
Just checked on ATTs website and I have "LTE UNL SMT VVMT" data plan.
Thanks in advance for all the feedback guys!

Also, I think its important to note that even if I connect to WiFi, the problem is still there, reception drops and goes up consistently. I've missed countless phone calls and have had to resend a vast amount of texts. I get all my texts together every 4-6 minutes. PLEASE help =/

Did you ever get this resolved. I have the same problem at my house, calls drop frequently and data seems to be not available at times.

Y did u resurrect this thread lol, a new post might have been better. None the less, try the telus KJ3 radio if u don't have LTE in your area, it has really good voice quality, and consistent data rates. If u do have LTE use the new UCLA3 one

FYI: PRL 13xxx means you're on the new Hybrid Network

Originally Posted by Gav508 Tonight I called tech support from Verizon and was surprised to get in touch with a very knowledgeable rep. The Hybrid push is a known issue, but ONLY for certain customers. These customers are in certain areas and are either former Alltel customers or customers that are accessing former Alltels equipment. I to have the 15008 PRL, however my location, New Jersey, I am not affected by the Alltel issue, and even though she said she would send the update to my phone, she stated that it can cause other issues. Since she seemed very knowledgeable about this information, I decided to take her advise and stay clear of this update.
For any of you guys using Alltel towers or equipment, all the info you have read is correct and this pushed update should serve you phone well. Just first verify you are in that Alltel local.
Myself I suffer from loss of internet sometimes moving from one place to another. (home to work). She asked if I frequently get the cannot connect for internet message. I do. She also asked if I get the 1X instead of 3G frequently. I do. She stated that this is a know issue with the Thunderbolt and it can be rectified very easy by doing a full factory reset from settings. Since I was having more issues with the Internet then the phone calls I am going to try this fix. I hate reloading and setting everything back up but I am going to try it anyway.
For anyone thinking of this, this operation puts your phone back to factory release condition. You will lose all contacts and data info. Make sure your contacts, calendar and misc info is backed up first. If you have a Google Account everything is and will reappear after you re sign back in.
Update from the OP: I said 13xxx, but this number could be different for your area. I honestly have no way of telling how many different PRL's there are or which number would say that would definitely tell you that you're on the Hybrid network(If there is one in your area.) I just know my results and that my PRL number changed.
On a quest to figure out why my phone had 3-4 bars of network signal, while my wife's phone had 0-1 bars even when they were next to each, I found this out in the process. If you're on PRL 15008, your phone is connected to the old Verizon Nationwide network. While if your phone shows PRL 13xxx, then your phone is connected to the New Hybrid network. I was on 13004, while she was on 15008. If your PRL shows 15008, I highly recommend you call Verizon and have them upgrade you to the Hybrid network, as this GREATLY increased my wife's signal and fixed her voice calls reception. (Not sure if this does anything for data. She always had good 3G and we're not in a 4G area.) They will push the update to your phone and have you leave it on for a few hours. Afterwards, I pulled the sim card and battery out for 30 seconds, replaced them and let the phone boot up. After 10-20 minutes, the radio will locate the nearest tower and my wife's phone auto updated its PRL number from 15008 to 13006. She now has a constant 3-4 bar signal and her time without a signal is significantly lower. (Same as mine.) Also, if you're rooted, make sure you know the correct stock firmware/radio version as they will probably ask you for this info.
P.S. I would only do this if you're having voice(not data) signal problems like my wife phone was. My wife phone shows 13006 and mine shows 13004, so PRL's can be different numbers for your area. So again, this may help some people and this may do nothing for others. If you already have a great signal, I would leave well enough alone.

yeah, I have 14001 too. Are you on a legacy Alltel plan?
I am on 1508 and in a 4G area. I don't know about the hybrid network or what not but I know that coming from Tmobile, I have great voice reception.
Just today I started to get 4G at my apartment. The coverage map always showed me in a strong 4G area but I was only getting 3g until today.
That is my first time hearing about 14xxx. But it could be the correct PRL for your area. Wouldn't hurt to call and find out. Also, have the regular Verizon plan. Not sure what the legacy Alltel plan is, as I never had Alltel service. I'm located in Central Florida btw.

I sure am, didn't think about that, goo call man! Would it screw things up to change over to hybrid? for example i still have unlimited messaging and internet for like 15-20 bucks a month way back from my alltel haha and would HATE to screw that up.
I'm on 15008 in Houston my phone is set it LTE mode (no switching to 3G) and I almost always have full bars and can get D/L speeds 20-30 easily.

Have you downloaded the 4g fixes for the VirusRom?! I hear they will bring your speeds right back up to par! I am not in a 4g area therefor i can not confirm but a lot of other users have said after they downloaded the fix everything was back to normal!
Just thought i might see if that helps. Good luck!
I called Verizon and even got tier 2 tech support...they said they have NO upgrade for PRI......he told me to pull the batter..then the SIM card......and see if it helps....I still have 15008 PRI. The tech informed me that it depends what part of the city you are in. Maybe your wife got the wrong tower when you activated the phone and she got the 13000 when you pulled the card. Do not think there is an upgrade for this.
That is why everyone has a different PRI

I have just been lazy and haven't fixed my signiture, I am running the Das BAMF rom. Although my 4G sucks on every rom. It cuts in and out, and so forth. Unroot my phone, instant 20-30 down speeds every time.
So what does it mean when my PRL is 1?

Verizon GS3 4g Connection Issues

Have any Verizon Wireless Galaxy S 3 users (besides myself) noticed the following symptoms:
1) Phone doesn't connect to 4g LTE until approximately 15 minutes later (even in an excellant 4g coverage area)
2) Phone connects to 4g LTE then disconnects approximately 15 minutes later and drops to 3g (even in excellent 4g coverage area).
3) Phone shows 4g LTE connection, but no data can be transmitted/received (tested with speedtest and a google search in the browser). This one is particularly bad, as there is currently no way I am aware of to turn off the 4g radio)
I've spoken with VZW technical support and they want me to replace the phone to see if things get better. I'm not quite sure it's a hardware problem.

I know this sounds ridiculous to do with brand new phone but here is the truth. They factory flash those bad boys using octopuss strand array cables with one machine and sometimes they receive a bad flash from the factory. Try the following steps
1. Go to options>settings>mobile and wireless networks>mobile networks>toggle mobile network on and off. (is it acting better?) No? then..
2. Factory data reset the phone. (is it acting better now?) No? then..
3. Using odin reflash the stock ROM (is it acting bettery now?) No? then take it back.... your phone is officially broken.

Thanks so much for the tips. I searched prior to posting.There has been another post after mine with someone talking about similar issues.
Tried number 1 and 2. No dice.
I'm hesitant with 3 (although I've flashed/odined many times in the fascinate). Will refreshing stock up the flash counter? I may just swap out the phone in store. This would at least give me an account history showing issues.
When I have new info, I'll reply.

I really hope this update doesn't effect the kexec work that is already underway
Verizon LTE is fast but...
It sucks at connecting and at staying connected. My HTC Thunderbolt did this, my Droid Bionic does this, and my co-workers Razr does this. LTE is fast when it actually works properly.
I'm not able conenct to 3g or 4g. Without Wifi I'm getting no data services.
As promised, I have an update. I went to the VZW store and they swapped out my SIM card. No change. The same issues I described in the OP were encountered.
I've performed the following testing to help determine if my specific phone had an issue or whether it was just the LTE service in the area. This isn't the most extensive or scientific test, just a quick and dirty test.
The procedure was as follows:
-Compare phone signal strength in Settings -> About Device -> Status (within phones approximately 5 feet of each other)
-Compare speed test results using the SpeedTest.net app
My office:
1 person in my office also has a vzw galaxy s III. We are running the same stock system.img (I535VRALF2).
- On average, his signal strength was -88dbm, mine was -84dbm. Definitely within normal range for a decent LTE signal.
- His speed test results were similar to mine (within 10% for each direction)
1 person in my office has a Droid Razr (non MAXX) running ICS (important as ICS measures signal strength differently than GB).
- On average, his signal strenth was -95dbm, mine was -91dbm.
- His speed test results were very different than mine:
GSIII - 66ms ping, 8.5MBit down, 12.2MBit up
Razr - 61ms ping, 18.9MBit down, 9.1MBit up
A friend's house:
My friend also has a vzw galaxy s III. We are running the same stock system.img (I535VRALF2).
- On average, his signal strength was -104dbm, mine was also -104dbm. A fairly poor LTE signal.
- Our speed test results were similar (approx 4MBit down, upload was intermittent (would sometimes stall out) approx 0.5Mbit up)
VZW lists 4g coverage as "Verizon LTE (non-extended)" in both areas.
Conclusion:
The difference I encountered between my GSIII and the Razr was alarming, but again, this wasn't the most scientific test (and anyone familiar with the speed test app will tell you that it's usually best to run it several times (unfortunately, I was pressed for time). Just wanted to get an idea of encountered differences.
I can second what tillithz heard about an update being released to address the 4g connection issues. I heard the info from a VZW store employee (so take that with a grain of salt).
I'll be keeping my eyes open for details on the rumored update (and wether or not it breaks our current root/CWM/custom boot.img flashing abilities).

Sounds like the issues I had with 5 (not exaggerating) GNexs before I gave up on the phone. It was a hardware issue. Hopefully Samsung didn't let this issue slip to the GSIII

Guys I seriously think it's a Verizon issue. I don't know one person with an VZW LTE device that doesn't have problems connecting.
I had a Korean GNex that never dropped 4G. I had 5 Chinese models that never held a signal at all (non-data included) for over ten minutes. For once I don't think it was Verizon.

Same issues
I have not done anything to my phone. It is still stock. While using Google Maps, it has managed to reboot 3 times on me. It has also managed to lose service two times while using Google Maps before rebooting with the "Searching for GPS" message. The night before I could NOT send SMS/MMS messages. Had to resort to Google Voice. Any thoughts would be great. I don't believe I have been holding it incorrectly as I have a BT headset. I'm randomly getting searching for services also. I don't think it's VZW with my Rezound, I would never lose WIFI, 4G, or calling service. Just wondering if anyone else is having this problem?
I am coming from the Incredible so I have never tried 4G at my house before but 3G has always been strong. I picked up my S3 last night and only 3G will connect. According to Verizon coverage maps I am solidly in a 4G area. Not sure what's going on.
Piss-off Verizon!
So I am having the same issue on mine and my wife's phone. Both pre-ordered in June and received on the 9th.
I stream music in my car while I drive to and from work an hour away. This is extremely annoying as I have to constantly fiddle with my phone to get the data connection back while I'm driving to get my music back.
I called Verizon twice and had the SIM swapped out on mine to test if it fixed it. It fixed one issue of signal strength, but not the dropping of connections. Here's my problems:
- Going from a 3G to a 4G area, signal drops out to unknown in the About Phone > Status page for about 30 seconds or more
- Sometimes it just stays at 3G and never switches
- Going from a 4G to a 3G area, signal drops out to unknown in the About Phone > Status page for about 30 seconds or more
- While it claims I have 4G, there are many times where I cannot get any data connection at all where Facebook says network connection error or speed test doesn't work at all and web pages won't load
- One issue fixed after the SIM swap was that under Settings > More Settings > Mobile Networks > Access Point Names it is now switching from EHRPD and LTE more often. Still not perfect, but I'm assuming that it stays in EHRPD mode when in an extended 4G coverage area (not sure about this) but before it wouldn't use the LTE option no matter what
Before the SIM swap my data connection dropped out completely in the middle of a city known to have great 4G coverage and would not come back no matter what I did (airplane mode on/off, mobile data off/on, phone reboot)
Software reset didn't fix any of these issues either.
Here is what I've decided about some of the issues they are having based on my experiences driving around so much. It seems as if the phone cannot negotiate with the towers correctly. It's as if it needs to drop the 3G connection before it can negotiate a 4G connection, hence the 30 seconds of no data at all, and same for going from 4G to 3G, it seems it can't negotiate without first dropping your current connection. 3G to 1X and back has no issues.
I know this is long, but I want it detailed as much as possible. I had gotten the Bionic when it first came out and it did the same thing, where I could never get a 4G connection when it was supposed to or go back once acquired. The main difference is that my Galaxy S III has WAY better battery life than the Bionic had. So they seemed to have cured the battery drain when searching for a 4G tower. I'm still pissed at Verizon stating I'm in a 4G area and then never getting that connection at home, let alone barely getting a 1x connection. My dBm levels are usually in the -95 to -104 area when at home...I'm in a 4G area now and it's at -112 with an asu of 28 while at home it's usually 1 asu. Hope this helps someone else out. I don't know if a phone swap is going to fix these issues.
Verizon has told me that they are looking at a software update sometime in September...I'll believe it when I see it. In the mean time I have 7 more days to decide to keep the phone with no Verizon tech knowing what they are doing or able to troubleshoot their way out of a brown paper bag.
I am getting a new phone shipped out to me tomorrow. I will let you know if the same thing happens or it is Verizon.

I have had symptoms comparable to these, 4G stopped working in areas where it should. It would occasionally go back to 4g, only to not actually transfer any data. My phone was fine before this, and has been fine ever since. In my case I believe flashing CM9 for a bit could have triggered my problems. I have no explanation for why my phone randomly started working properly again.
I'm doubtful that this is a hardware issue, and I am hoping future updates may address radio issues.
Just an fyi, I have talked to multiple Verizon reps and changed sim cards to get nowhere. I'm at the point where I'm about ready to return it for another phone to see if that helps.
Verizon claims this is not a well known issue or widespread. I beg to differ. If it isn't widespread, then it must be a defective unit imo. I also think I got a retarded rep, he tried to tell me updates come straight from the manufacturers and we should see an update soon after a phones release haha. I asked for examples of phone release dates and the date of the first update...He couldn't provide me with any. I then asked why the nexus got the 4.0.4 update 2 months after every other carrier and he stated, well sir we don't release the updates until they're tested. Ah, so you do control the updates!
Needless to say, I'm getting tired of this crap. I'll let you know how the replacement goes.

Galaxy S4 missing calls, not receiving calls - Compromised solution

Symptom: I just upgrade from iphone 4s to Galaxy S4, after about a month use, I missed 4 calls from my friends. The phone did not ring at all, and there was no missed call in the log. This is a very serious problem. someone say she almost broke up with her bf just because of this, :laugh:
Solution:For now I found the solution is to turn off the LTE by go to setting=>Connections=>More networks=>Mobile networks=>Network mode and then choose "GSM/WCDMA". Then you will not miss a call.
Compromise: your data speed is reduced to 4G HSAP+. But if you have 200MB plan and only receive emails like me it does not matter(poor solution for people who has unlimited or 2gb+ data plan), plus by using 4G HSAP+ instead of 4G LTE you get better battary life.
Explaination: I lives in Pullman WA where we have LTE here. Some of my friends using a LTE capable phone (iphone 5, other GS4, nokia 920) also met this problem sometimes (this happens totally random or say I cannot conclude a situation when this will happen). The general idea is that LTE can only handle data transfer but not voicecalls (you can make a call with the LTE on and you will see that your phone swith from LTE to 4G), so if you are using the LTE network and your phone is connected to wifi (at this time your phone is using wifi data not LTE and then you are not connected to the tower at all, this is my guess, I am ME engineer not a communication engineer) and it's on sleep mode (these situations are my assumption) you may miss the phone call.

Symptom: I just upgrade from iphone 4s to Galaxy S4, after about a month use, I missed 4 calls from my friends. The phone did not ring at all, and there was no missed call in the log. This is a very serious problem. someone say she almost broke up with her bf just because of this, :laugh:
Solution:For now I found the solution is to turn off the LTE by go to setting=>Connections=>More networks=>Mobile networks=>Network mode and then choose "GSM/WCDMA". Then you will not miss a call.
Compromise: your data speed is reduced to 4G HSAP+. But if you have 200MB plan and only receive emails like me it does not matter(poor solution for people who has unlimited or 2gb+ data plan), plus by using 4G HSAP+ instead of 4G LTE you get better battary life.
Explaination: I lives in Pullman WA where we have LTE here. Some of my friends using a LTE capable phone (iphone 5, other GS4, nokia 920) also met this problem sometimes (this happens totally random or say I cannot conclude a situation when this will happen). The general idea is that LTE can only handle data transfer but not voicecalls (you can make a call with the LTE on and you will see that your phone swith from LTE to 4G), so if you are using the LTE network and your phone is connected to wifi (at this time your phone is using wifi data not LTE and then you are not connected to the tower at all, this is my guess, I am ME engineer not a communication engineer) and it's on sleep mode (these situations are my assumption) you may miss the phone call. But when you wake up your phone and ask your friends to make test call. you will receive the call.

Yes, they give me a new sim and my old sim stop working after they activate the new sim. But I put that new sim into the iphone 4s first before I put it into the GS4, Will this cause the problem? Do I need to ask them to issue me a new sim?
Thanks for the reply
Probably not. If you got a new LTE sim then that should not be the problem.

Mobile networks => network modes does not exist on my AT&T GS4.... Just and FYI.

i experienced this before.
this is because LTE network is down in your area, that is why!
it' like you connected to your router wifi at home, you pulled the internet cable. but your phone still connected to the wifi. it just wont let you surf web since there is no internet connection, but your phone still connected to your home wifi router.

so you never have your DSL or cable internet down? Samething with LTE network, the lte tower is down. nothing to do with what phone you using!
It takes att about a week to fix it when they received enought complains! that happens in my case, when you call them to report LTE network tower is down, they think you a idiot! Telling or guiding you how to setup your phone! There's nothing wrong with your phone! The lte tower is down!
This is good.

Ummmm but yeah dumbass we're not talking about a whole network outage.
Everyone would be dropping calls/texts in your scenario but that's not what this is about.
My wife's phone misses calls/texts randomly while moving and connecting to different towers over a 140 mile radius, she has a GS4. Now here's the part that makes your statement dumb. While this is going on, I receive calls/texts perfectly fine on a GS5 sitting right next to her the whole time.
It's a device issue, not a network issue. Something so simple normal monkeys can figure out.

Wow are you just born a total moron or was it a learned response. It's still relevant if it happened on a new phone purchased in February plus there is no definite fix without sacrificing quality. Don't assume you know everything...just makes you look more the ass than you already are.

why would you want to turn off LTE?
there is a code for Note3 that let you turn off LTE and stay at 3G. why would you want to stay in 3G instead of LTE ?

From what I have read here I wanted to turn it off as a troubleshooting step and see if it would fix my not ringing problem.

3G Issues

First of all, my LTE works fine, this is only an issue with the 3G radios. Basically, I often have issues with 3G actually sending and receiving data. When it does, it is slower than 1X for me. It drains the battery at crazy rates such as 20%/hr with little to no use. This has happened regardless of rom, although now I am on the stock f1 update and unrooted. I bought this phone used so there's no hope of a CLNR. I've had it "fixed" by samsung twice and nothing has changed. Any ideas? I have an upgrade but I'm waiting for the One or the 5S and REALLY don't want to use it on a phone I wouldn't be happy with.
Same exact problem here. 4G works fine. 3G is essentially useless. Often when it changes to 3G, I wish it would just go to 1X so that at least it would be functional. I've never really found a solution. The other day my phone was in 3G and I tried to send a text msg with a picture. It took almost ten minutes. Completely useless.
Friends with 3G Verizon phones never have any problems. They always get a solid 3G connection. I used to be with Sprint (useless) and set my Evo to roam on Verizon because the 3G was so much more responsive and quick than Sprint. Not seeing that with my S3.

Yeah none of my friends have issues either. My friend with her iPhone 5 was using it next to me and it loaded pages in just a few seconds, still slower than 3G, but mine took almost a minute.

Forgot to mention... My wife's also got an S3. Mine's rooted with CleanROM and LK1 modem. Her's has the latest update. She has the same issues with 3G. She also had them on MB1.
Fortunately my phone doesn't flip over to 3G often. But when it does, I just stick it back in my pocket, because it won't do anything useful until it switches back to 4G.
I've never found the answer to this problem, but I'd really like to. I understand that this is a 4G phone, but it should be able to fall back to 3G with no problems.

Theoretically AOSP ROMs should have absolutely no effect on data or voice since they don;t touch the radio firmware.
I was in a 3G zone this evening and did a speedtest.
23 kbps down. It died when trying to run the upload portion of the test. Friends with regular 3G phones routinely get 800 kbps - 1200 kbbs down.
I agree. It has to be the phone. And given that it seems to happen across multiple radios and only to some people, it's probably hardware related. Doesn't matter when I get 4G. Sucks when I can't.
I'm going to be at camp for a week soon and I only get 3G there so I'm strongly considering buying a used 4S until a new phone comes.
I have 3g signal in the house.. wide open all bars with a network extender..I go outside to get 4g, then it will send pic messages. dumbphone

I don;t think its a Samsung problem, more like a Verizon wide issue. If you look in the verizon user forums, all the Iphone and HTC and Moto folks complain about the same things.
https://community.verizonwireless.com/thread/784496
I don't think so. Not only are they not complaining about just 3G, my friends' phones work fine.
Not only that, but my GNex I had before this somehow consistently had 2 mbps dl speeds on 3g.
Friends on Verizon with 3g only phones get excellent speeds where I am at. Verizon 3g is not the problem around here. On 3g phones, it is fast and responsive. When switching from Sprint, I went with Verizon based on the quality of its 3g.

Too bad you have to rely on something else that you pay for independently for your phone to be able to do its job. These phones should work on 3G. I have to imagine that there are some who don't have 4G that have to rely on 3G. Maybe they just don't get this phone, or get it and return it?

[Q] Constant Loss of Signal (Sprint)

Is anyone anyone else constantly losing and regaining signal? I just noticed it once I got home from work. I'm unlocked and rooted. I updated the PRL and profile. I noticed the signal lose after this, but I wasn't paying much attention before I got home.
Anyone have any advise before I RMA this thing?

Sweet, thanks
Yes, I was just about to create a thread asking the same thing. The signal icon turns to an empty triangle randomly for no more than a minute. It's been happening all day =/
The phone is locked and 3G is working. Not sure about LTE just yet.

I have experienced random signal drops, even when I have full bars. It might only happen when it's switching between LTE/HSPA, but I haven't really payed attention.
Sprint is doing a lot of backend tweaking to support the Nexus 5s. Lots of performance changes hour by hour as they try and set up the network to allow unlocked Nexus phones.
First time allowing a phone on their network that's not sold them so these are all part of the growing pains. Just keep giving Sprint productive feedback so they can iron out the issues.
I went to the online chat and the guy apparently "refreshed the network and fixed the glitch." I thought he was full of ****, but I haven't lost bars yet ^.^

I have been having the same problem at work and I can trace it to switching between network types. LTE to 3G to 1x. At home I'm good to go. I think it may be because Sprint installed a micro cell in our building and it's not LTE compatible.

Might just be a not so great radio software/firmware at the moment. Most likely future updates will make it better. Now, that doesn't help you in the interim but that's most likely it.
my worst fear.. LG's are notorious for dropping signal. I know this because my old LG Optimus G did it, and many others had this problem as well. You can google or look at my old posts.
I ran a Network Signal Pro log last night and it was a constant signal/no signal. Not sure if it was just voice or voice and date. I have attached it, if someone who knows how to read that better than me could look at it that would be great. I'm running another log right now, will be 60 minutes with a 30 poling rate. I'll post that later. The signal is pretty weak since I am in a hangar at an airport. So we will see how it is.

Why should any "tweaking' be required? GSM networks have let on all phones for years. It would seem that once Sprint allows a phone on the network, it should be in the same position as a GSM network with respect to phones that it did not sell.
Also OP, do you mind providing your general location?
Here is the next log. Never lost a connection.
The only difference I see here is EVDO A at work vs EHRPD at home. Wonder if that is part of the issue?

Ah - other side of the country. Didn't see you had it in your profile as well, my bad.
Other side of the country which makes me nervous that it's not a sprint issue - I'm in Detroit near campus martius and still having similar issues.
it isn't only Sprint, it happens in Rogers and Fido in Canada as well. So I believe it is LG

I feel it may be a sprint issue only due to it constantly losing connection of EHRPD but it being fine now that I on on EVDO A at work. It is the same radio and antenna for EHRPD and EVDO A, right?
I'm going to Salt Lake City this weekend, I'll have to see how it preforms there.
