I have the same issue. I'm in the SF Bay Area and even though TMobile's site has where I live and work as dark green (excellent 4g) I am lucky to get even one bar. Half the time I get network errors. Anyone else with TMobile experience anything like this? Any chance it's something that'll get resolved before my 30 day return period ends?

do any of you have other tmobile phones to compare signals with? if so, do that and if there are major differences talk to a tmobile store about getting a replacement.
these might be isolated incidents, because the majority of people are getting fully functional units

im in SF bay area (mountain view)
my data speeds are *top notch*.
you are either in an area thats out of tmobiles footprint or have a defective unit.
best bet would be to wait till tmobile actually gets the GS4 on display in the store.
when they do, go to your nearest tmob, and do a speedtest.net comparison with the demo model, and yours. if they are similar, then your part of the bay is legacy; if there is a big difference; 3,4 5 etc megabit difference; your unit may be worth exchanging for a new unit.

What part of SF are you experiencing this? My GF lives by the ballpark & she won't switch with me if she gets ****ty service.

I have excellent reception (bars) on my S4.
Way better than my Note II.

I let you know. When I get my phone next week. I do a speedtest and a screenshot of the phone signal in the settings menu.

Im getting much improved signal compared to my Gnex and Atrix HD.

Still no signal inside my workplace. Will do more tests. It does seem the signal is more stable, but it's only been a couple days.
Also, 4G LTE flashed for a couple seconds at my house. I live in the D.C metro area. Nice.

I have the HTC One in the Phoenix market. LTE is difficult to find more than a few bars on. 4G HSPA+ has been very easy to get full bars on.
I'm somewhat convinced T-Mobile is still working on building out in even LTE and re-farmed markets.

Its funny how T-Mobile improves their network and yet many years later I still don't have service in places where I had no service maybe 5-6 years ago. And on top of this I noticed even more dead spots. I think T-Mobile should be working on that along with building penatration.....I would much rather have 3G everywhere then LTE almost nowhere.
Lately it became very frustrating since my wife has no service at work, i have no service at work, and i recently moved to different location and still no service....and God forbid I loose my wife in the mall, I have zero chances of finding her because no T-Mobile service inside.

Just got my S4 today and did not realize theres LTE where I work (fremont) which I never saw on my note 2. Even went out to lunch and was still getting LTE the next street over. So just to test I'm now back on my note 2 and it is not picking up LTE at my work. That tells me the radio on the s4 is much better.

yea its something with the S4's phone/modem. I get bars and shows signal strength of 3 to 4 bars and i can make call but no internet in certain areas all around Los Angeles County/Orange County/Las Vegas/NYC. To test it i had my buddy go with me with his LG L9 and my buddy with his LG L9 phone would work fine on the calls and data/internet meanwhile my S4 would only get calls but no data as if it was a deadspot. i would have to go around like 1/4 or so before it would work again. its really strange not to mention annoying. I noticed this started happening to me after i upgraded from MDB to the MDL baseband and after i unlocked the phone using the "debug service menu". i wish i knew someone else with a stock TMO S4 to test my findings out more. I also cant wait for more tmo S4 modems. ive been thinking of ODINing back to stock MDB to test my theory, but i have just been lazy.

i think it was a TMO LTE tower upgrade issues. after doing the Settings > More networks > Mobile networks > Network mode > and switching between the WCDMA and GSM one or the other now will work. better to have some internet than no internet, weird how the S4 just wont switch over to the working GSM internet if WCDMA fails....i guess when they coded it they figured if u have bars it "should work in theory" but they were wrong ...personally i think this should be considered a "bug"

I thought I was the only one. I found that if i keep my diztronic tpu case on while in my pocket it destroys all signal for some reason. I take it off and its fine.

I further tested my theory and went without my case all day. It didnt appear to do anything different at all. I am on CM10.1, I think I might go back to stock for awhile to see if it changes the fluctuating signal issue.

Just curious on how everyones signal is and which baseband they are on?
I'm on M919UVUAMDL and I have seen up to 15% of no signal while my S3 had 0 signal loss in a regular day.

[Q] LG G3 Three UK Signal Dropping

Hi all,
Is anyone else experiencing terrible signal on Three UK? My dad just got his G3 and compared to his Nokia 925 signal on Three is atrocious, and seems to drop in an out constantly?
Anyone else experiencing the same?

Not on 3 but I'm on ee (T-Mobile) and I have some prob outs at times that I found has been bit strange but most the time I have great signal.

I am on Three, had no signal concerns at all except in areas of weak signal. The phone doesn't seem great at maintaining a connection when signal is weak, whereas other phones might stay with 1 bar this drops to none, but otherwise signal is as good as can be expected.

No problems here
Sent from my LG-F400L

I have had this problem on 3 UK. I found that going into network settings and choosing the network mode without LTE stopped it from happening! Any idea why this may be anyone? Do we have defective units?
Matt

The g3 is just very slow at finding signal when its lost signal - what is happening is you are losing signal (even if just a split second), any other phone would probably instantly reconnect but the G3 seems slow - this is all software based (well, radio firmware) and can be fixed (and word on the street is that it will be fixed in the next, August, release).

Thanks for the info, I won't be sending this off any time soon then! Also thanks for your unroot and chromecast volume fix guides they have been very helpful.

Wouldn't enabling fast dormancy help to find the signal quicker if it loses it?

I have also seem a connection problem on three in the UK. I figured switching off lte stopped it happening so much but then again I get 4G free and three tell me I have good signal strength for it so it seems silly to turn it off. Having said that I haven't seen it pop up once yet. Anybody tell me what the signal icons are on the G3, I have only had H so far? Cheers

I haven't seen the 4g logo yet either as I live away from any LTE areas, I've seen H and H+, 4g will show up as either LTE or a 4g symbol so I assume that your phone isn't connected to LTE/4g if you haven't seen either of those

Yep that's what I figured. Tweeted three cs but didn't seem to get much help. Thought maybe it's because I'm a SIM only customer. But I have checked there website and to all intents I should be connecting. 4G is good on my area. Not sure what else to try?

Enable fast dormancy for the 3 network. 4G works great on 3 in cities where it is supported.

How to enable fast dormancy? Website gives my area a good signal. I don't even get H+ which I did with my galaxy s3.

Have you tried the options when you enter 3845#*855# into the phone ? I had to use this as I was not getting LTE. See here for more info http://forum.xda-developers.com/lg-g3/general/mod-root-activate-lte-g3-t2819387

The option its already in my network settings menu and switched on. Are these different? Just can't put my finger on it.

I am having the same issue with my LG G3 on Three, the signal is much worse than my galaxy S3. Drops out randomly in my house and then takes ages to get a signal again.
Wondering whether to send it back our not as a phone with bad reception is kind of pointless! Anything perhaps fixable with a new firmware for the radio?

Yep exact same issues. Hoping it's not the phone (bought it myself not from three) really like it and Up to now three was great ? gutted.

It seems the phone either had really good or really bad reception. In poor area's it's quite flaky and can drop out easily when moving between rooms or even how you hold it.
If the reception is good you can get some great speeds on 4G though. Hoping they fix the issues with low signal strength soon as it's quite annoying.

Had a text from three saying they were going to fix my issue within the next seven days. Not picked up a 4g signal at all yet. So watch this space.

I also had problems with signal. I got a replacement SIM & that seems to have improved matters.

[Q] Data service iffy on LTE - phone or Straight Talk issue

Hi,
I've been having data issues with my HTC ONE M8 on Straight Talk for the past couple of weeks. the data service for some reasons got really iffy. before everything was absolutely fine. now sometimes I cannot access data at all, sometimes something is working and something doesn't.
when the data doesn't work:
- most of websites are not reachable
- google.com seems to work normally
- google maps might work; sometimes very slow, sometimes not working at all
- ookla speedtest won't start, but if I set a fixed server it might work
- facebook.com might work in the browser but the app doesn't work
- refreshing the page seems to help
on WI-FI I have absolutely no problem. everything works fine.
phone and txt messages work without problems.
on 3G (HSDPA) everything seems to work fine. I see problems when on LTE.
anybody has the similar issues?? any suggestions?
many thank!!

I am having the exact same issue! So frustrating, I don't want to use 3g if we should be on "Full speed 4G LTE for up to 3GB"!
tried so many different APN's, no luck can't get over 2.5mbps with any of them

I would be happy with anything that works right now. the service is just NOT WORKING. I am paying for a service that doesn't work and that's not acceptable.
I opened a case with the help desk; useless. I was talking to people who don't understand the basic concepts of networking. made me add a proxy to the APN; no difference at all.
then I put a complain on Twitter and got some other people "helping" via email. at least they asked for the address of where I am always having problems; hopefully, they check out the service at the antenna. I think it's not a BTS (antenna) issue but something related to their proxy, firewall or network gateway since google.com works without problems!
I talked to a friend of mine who has StraightTalk as well and he said that he had the same issue last year!

I had the exact same issue with Net10 it is so annoying and unacceptable =(

Have you tried calling straight talk a call

U can try this from what I know ur phone gets chooses the strongest signal tower example u are around 3G tower it has a 9/10 signal and the 4g tower is a 6/10 strength it goes with the 3g hope this helps in ur dial pad dial *#*#4636#*#* then Phone Information....Scroll down a little bit to Set preferred network type. I was able to lock in LTE only doing this and gave me the fastest signal on my device hope with works for u. If u can post ur original settings before u change to lte option only on this post so u can always revert to ur original setting good luck.

if I lock it to 3G it actually works well. I will try your suggested settings.
on another note I wonder if it's an issue with the phone radio implementation. my Nokia/Windows phone sees LTE very very slow but it doesn't stop working completely.

Hmmm Idk but anything's worth a try what settings do u have it on already?

if I put it on GSM/WCDMA (so no LTE) data works fine in 3G.
and if I do a speed test in 3G it gets about 5Mbps in download vs 1, 2 or 3 Mbps when LTE works (ZERO otherwise)

The exact same thing started happening to me two or three weeks ago. More often than not, the LTE connection simply doesn't work, and when it does, it's excruciatingly slow (anywhere from 0.01 to 2.50 mpbs, and usually less than 1.00). Do you guys have AT&T or T-Mo sims? I'm starting to wonder if going to Cricket would solve the problem, but since I'm running an AT&T sim, I'm not sure if anything would change since it's on the same network.
Straight Talk support is worthless... they think a factory data reset will fix it, when it's clearly a network issue. I just told them to stop right there and started troubleshooting myself. That's a good tip about dialing *#*#4636#*#* and turning off LTE that way. It seems like that is where the issue lies - I'm having good luck with HSPA; it's slower than LTE should be, but at least it works. It'll do as a stopgap through the end of my billing cycle, at which point I can decide whether to go somewhere else or get by on HSPA until they fix whatever the problem is.

tried and on pure LTE it simply doesn't work. the only way is to set GSM/WCDMA and it goes at 3G speeds but at least it works.
the funny part is that Google.com always works, whatsapp works, googleplay works. so it seems a problem with throttling or filtering to me.

I have ST on AT&T.
a friend of mine with iPhone 6 down in Newport has no problems. he sent me screenshots of speed test at 15Mbps.
I really wonder if it's some radio firmware issue...

Ironically, I ran into something very like this too recently....I was on an at&t straighttalk sim...lte had been OK prior to me updating to 4.4.4. It was never spectacular, but it was, at least, lte speeds. After the update I noticed it had become really sketchy...just as described, pretty much; even when mine worked it was trash. 3g was much better and totally stable. I thought it might be the update, but long story short, it wasn't. I inserted a friend's sim from tmobile and got full lte with no issues.
Now, in my case, I had been using a shaved down microsim rather than a nano sim, so I thought, maybe that's the issue. I noticed when ordering the new one, the tmobile one actually said htc m8 compatible on the page(plus my friend's legit tmobile sim got good signal and lte so I thought that's a good basis for comparison). Got the new one, put my number on it, and voila! I'm getting on average 20mbps lte. And it's very consistent too. So now I'm on the tmobile straighttalk sim and everything is fine.
Anyways, it's only $7 with free overnight shipping, so that's something easy to try. This wouldn't be the first time a new sim fixed all sorts of weird data problems with straighttalk either. I've been on with them for several years now and this is probably my 4-5th sim I've had to get for various reasons.
So, anyways, your mileage may vary but that fixed it for me. Hope it helps.

it seems ST on T-mobile is not having the same issues as ST on AT&T. the problem is that T-mobile coverage is not so good in my area.
I tried my phone in a different location (400 miles away) and had the same issues.

I've done some more testing.
it is really weird that Google.com works flawless while any other site seems not to work.
activating "save data usage" in Chrome seems to help. however it doesn't solve the problem. sometimes pages needs to be reloaded a few times.
even when LTE works, the OOKLA speed test gives me 2Mbps in dowload and 5-6Mbps in upload. so no matter what, I am better off with 3G.

I found an interesting thread here on XDA. I am not rooted at the moment and can't try.
<<
If you are rooted there is simple FIX, simple disable FD8 (Fast dormacy 8)
ro.ril.enable.r8fd=1
ro.ril.enable.pre_r8fd=1
Change both to =0 and issue will be fixed.
If your not rooted only fix is to keep HotSpot enabled than data connection wont break.
>>
I tried the hotspot trick but it doesn't work for me

Sorry to bump an old thread, but I just wanted to give a brief update. My LTE issues with Straight Talk went unresolved for about 6 weeks despite multiple conversations with customer service. I experienced this in Raleigh, NC, Greensboro, NC, and Virginia Beach, VA. Then for Thanksgiving, I went to New York City and New Jersey (the part just outside of Philly), where all data connections were unreliable. Yes, that means 2G, 3G, HSPA, and LTE were all spotty at best the entire time.
I ran out of patience after that, and since my billing cycle was ending on 12/4, I switched to Cricket when I got home. As soon as I popped in the Cricket sim card, everything started working flawlessly again. Cricket does limit you to 8 mbps down, but that's good enough for my purposes. The issue, if it's still going on, is with Straight Talk and not the phone.

Lollipop Fixed the Issue on my HTC M8
Hey all,
I've been following this thread as I too had issues with LTE on my HTC M8 using StraightTalk. When I first got my phone, it worked perfectly with LTE on ST. Then I ran the OS update that was released sometime near November. That's when I noticed the problems. I could run a search on Google but any webpage I would try to connect to would not load. The phone would hang and eventually time out. Your instructions to turn off LTE was great help. Pages load perfectly provided LTE is not used. I was getting really frustrated and you kept me from throwing my phone at a wall. Thanks for that.
So that brings me to this post. I updated my phone to Lollipop this morning. Thought I'd give turning LTE back on and bam.... works perfectly. I've been testing it all morning and so far, all pages load really fast. I will keep an eye on it for a while and post any updates but thought I pay it back a bit with the good news since you guys helped me.
Thanks again.
AC

thank you for sharing!!
trying to upgrade to Lollipop. unfortunately I am having an issue with the recovery (flashed from TWRP to a stock that doesn't work with the OTA and can't flash any other recovery -not sure what's wrong).
when I solve this issue and able to upgrade to Lollipop I will share my LTE test results

Signal Indicator Problem

Has anyone else been having a problem with their newly purchased Sprint S6 where the signal shows as 1 bar LTE on the s6 while other phones activated on sprint show better LTE signal at the same location? Even though the s6 and other phone's downloads speeds are the same, it always shows as 1, max 2 bars lte on the S6, although when placing a call the LTE indicator shows more bars for some reason. My family has two new S6's on our plan, and their both experiencing this issue. That and a few calls that didn't go through are making my dad freak out and wanna go back to his GS4.

Bars don't matter, what matters is Settings-->About Device-->Status--->Signal Strength.

I know, but I think there may be an error with the LTE indicator in the notification bar, and my dad says its driving him crazy.

Mine is the same.

i have the same problem. i updated my prl and profile to see if it would help and it didn't. then contacted sprint and they did a manual provision refresh. that seemed to solve the problem for now.

Mine is at one damn bar of LTE everywhere... doesnt seem to affect my speed of data usage... its fast... but it does have to search for that signal allot...

OK I think I see what ya'll are saying now. Just curious, what's your software version, OCF?? Also, anyone got a good fix?

Same here, on OCF
I noticed that as soon as the call connects, the bars shoot up.

I also have this issue on OCF. Question, has anyone rooted OCF yet? If so, which method did you use?

I am in exactly the same boat. I just changed from the S4, and at work we tested our phones side by side an S4, S5, and S6 and mine was the worst. I had to turn my LTE totally off in order to do anything. Please tell me this is something that Samsung can fix because I love this phone and don't know what to do.

Ya know,, 2 days ago I did changed my mobile network settings from Automatic to lte/CDMA. ALSO DID run an PRL update a d such but my signal had great actually, and my battery actually has improved alot since the change. Very well could be an Radio issue. That's what I'm guessing it is

Is it me or does this phone have a issue with making calls example tons of dropped calls, or do I need to get another phone

Guys, Samsung knows about this.... Supposedly will be rolling out an OTA soon to fix it,

Lets hope so. I'm convinced all of this poor battery life is from the modem / signal.

I was messing around if you just select CDMA you will not drop calls until a fix if you guys want to do that

The signal display mainly looks bad because it's a Tri Band phone. On your s4 it would display the voice strength even though you were connected to LTE. On the tri band phones it only connects to LTE, and the switches to voice when making or receiving calls that's why you see the signal jump up when making a call. LTE does not travel/penetrate as well as voice and CDMA, but good news is that it does not have too to get good speeds.
Check out an app called Signal Check. It's cool to actually see your real signal and it just some bars. It will also tell you what band of LTE you are on.

LTE does not travel/penetrate as well as voice and CDMA, but good news is that it does not have too to get good speeds.
Check out an app called Signal Check. It's cool to actually see your real signal and it just some bars. It will also tell you what band of LTE you are on.

I understand that but doesn't help the people that are getting tons of dropped calls like myself

Any info on a update I can't take all the dropped calls driving me crazy now

Even on OC9, we were experiencing the dropped calls. Finally, updated to OCF today, to see if it helped, but actually feel it may have gotten worse, seem to be experiencing more dropped calls.

Why will my OP3 almost never connect to 4G 99% of the time?

My OP3 refuses to pickup 4G in places that my old iPhone 5s and 6P always did. Why is this?

we don't know, we do not know where u r at or what carrier u are on and by 4G do u mean LTE

I got this the first 2 hours that I used my new OP3. It stayed on H+ for 2 hours then without reboot or anything and not even moving, it got LTE.

Check your APN settings and make sure they're the latest for your carrier.

I am having the same issue. I am on Bell in Toronto Canada. Some areas cannot get LTE. Some times my data just hangs showing full bars. Can't receive or make calls or texts. There are a few threads on different forums with people having the same issue. Hoping it is just a software bug that can be fixed with an update.

I'm O2 Germany and have a really good LTE reception. Look up what LTE bands your carrier is using and compare it to the specs of the OP3. Maybe that's the issue. You can also try to enable flight mode for a few seconds then disable it and the phone will connect new and then you might have LTE.
edit: Seems like Bell Canada is not fully supported but 3 UK is.

I get LTE fully at work just fine. But around my house and the neighbourhood where I live, I only get 3G whereas I used to always have 4G!

Hm I can recommend the app LTE Discovery. Then you'll see if there is any LTE network around you and if the phone receives it.

I have also the OnePlus X and that always gets LTE and it supposedly supports less bands.

I understand the icons are not showing you what you want to see but how about the speeds? Did you do a comparison or is this all strictly off of H v LTE icon?

Off of the H vs LTE icon to be honest

I am using my OP3 with mobile internet, using google map a lot. But the google map app eating too much data. Even if i download the offline map and trying to use offline the navigation. If i try to use the offline pre downloaded map without internet connection just does not work. After few seconds or minutes the map will become „blank” means no can see the streets and roads. Nothing at all. But if i turn back the internet on my phone everything coming back. But the point is, that is why i want to use offline maps to save my data bundles.
On my OPO it was not a problem, if i was using the offline map and turning off my mobile internet connection the google map was workng fine. I am using CM13/ Marshmallow on both phone.
Also it has never eat so much data like on OP3.
I am on Tmobile UK and using a 1GB data bundle per month. Before was using my OPO the 1 GB data was more then enough for a month using google map almost every day around 7-8 hours a day. I need the google sat nav for my everyday work so that is why using a lot.
But with OP3 only yesterday i was using almost 200MB and it was all the google map.
I was trying to disable background data traffic on the settings, and also the google map settings has some option but just does not help.
If i download the desired map via wifi and after trying to use the map offline it just become „blank” the map. I need to use the mobile internet to be able to use the offline map. Annoying…

AT&T in the US. I can't get LTE at work. Only H+, and sometimes just 3G.
My issue is that when I get into an area that is LTE for certain, the device doesn't pick it up. It stays in 3G or H+.
I then have to toggle the SIM settings on and off for the device to get LTE. Then it is fine until the next time I go into am area without LTE.
My apn settings are correct and my IMEI is mapped correctly.
Changing to LTE only won't work because then sometimes I would have no signal.

Have you installed OOS 3.2.4? If so go back to 3.2.2. There are known connectivity issues with 3.2.4. There's a little more info on the official OnePlus Community forum in case your interested.
