[Q] How's your signal strength? [LTE]

Hey all,
I'm curious to how your reception is on the VZ GNex. I still have my Rezound here and it seems like I'm getting about -20db worse on the GNex compared to the Rezound. I'm curious - has anyone else experienced this?
Thanks,
Super

yeah, and it is killing me. In the same spot in my room I had my rezound, I had MUCH MUCH better signal strengh. I could keep 4G all day, which is why I switched from sprint to verizon. Thunderbolt, Droid Bionic, Rezound, all worked fine. The GN looses 4G consistantly. This might be a deal breaker for me. I am going to try a custom rom in a min when it finishes downloading, but I doubt that will help. Also am on 4.0.2.
on the thunderbolt there was a setting that allowed us to change when it "lost" 4G signal. I.E. it would allow the phone to pick up a weak signal. Does anyone know if there is a setting like this? I know the signal isn't weak in my house from the previous phones, so it is either a setting like this, or the GN has a really crappy radio...

The 3g and 4g on my Nexus is very bad and not even usable. It is either dropped or barely working. Without wi-fi my phone would have been useless today.
If this isn't correct quickly I will have no choice but to go back to my Thunderbolt which was great!

Service at my apartment just sucks but it's getting the same reception as my OG Droid

I had a rezound and was certainly getting a better signal, 2 things I noticed on the rezound was the battery door actually had antenna relays in it, and also there was 3 settings on the rezound for network performance (performance, normal, and battery saver)

I get horrible signal strength in spots, like on my way home from work there are several short distances where it just drops the signal all together.
At home, my phone seems to just drop connection completely and it's having a hard time picking it up again. Noticed this morning it had been without network access all night. Rebooted it and everything was OK (strong signal) in the exact same physical location.

does any body know how to update roaming with this phone I tried *228 but that didn't work

I am having similar issues in regards to network dropping out. I can understand why 4g would -being limited coverage and all- but 3g should seamlessly pick up where it drops off, plus my voice signal is much lower -100dBmw vs -85/-90dBm which I got with my OG Droid.

You can't update roaming on LTE devices, as the sim card automatically does it. What you can do is a "sim reset" type thing.
Power off, and leave your sim card out for like 5 minutes. Put it back in and turn on the phone. According to multiple sources, this will cause the sim to have to re-register on the network, thus refreshing/updating your privs.

Rezound is way better reception wise. Matter of fact, the Rezound is better at a lot of key things! Ima give this a chance but I gotta say I miss my Rezzy!!

WOW.... my Nexus data was very bad and almost unusable, but now it is fixed!
I didn't want to, but I did a factory data reset and it resolved the data issues. Everything is solid connections now and holding steady. Before the signal was bouncing all over the place.
Give the factory data reset a try if you are having issues. Yes you have to start over but it's better than having a phone that doesn't work.
Phew... now I am happy again! I really thought I was going to have to go back to my Thunderbolt.

OK. I did some digging. I recommend all users download an app called sensorly. It would appear that the reported signal strength by default is 4G. Currently, my 4G is is teetering at -100dBm to no signal and that shows on my phone as no bars. However, I discovered that my 3G is at -90 dBm (excellent coverage). From what I have researched it would appear that the phone has issues handshaking between 3G and 4G which I am sure will be corrected in an OTA update.
If I go to Settings-Wireless & Networks-More-Mobile Networks-Network Mode-CDMA/LTE and switch to CDMA only my bars come up and my dBm appears normal in settings.
I am pretty confident this is a LTE/3G handshake issue. Just like when you leave your home and you are still barely connected to wifi and the phone doesn't know what to use, so all of your apps fail trying to connect. I think it is just the same.
Anyway, I hope this helps others. It has made me less neurotic finding this out.

I had the rezound and returned it because of the headphone noise. Got the nexus and it gets terrible signal and speeds where the rezound was great. Called Verizon and they are sending me another Rezound and told me it shouldn't have the audio problems. We shall see. I just know that the nexus is unusable in my house due to reception.

Network completely dropping randomly?

This is happening multiple times a day, randomly.
Ironically, I was at a vzw corporate store today getting a half off extended battery and incipio case, and it happened, i was driving home in the middle of a bluetooth call and it dropped, and while at work it drops every 10 minutes.
What the heck is going on? It even drops at my house, where i have "-93dBm" of 4G service... the notification bars will start at full 4G to none, grayed out.
This is extremely annoying and making my phone "work" a lot, thus killing the battery. It didn't make it through a 12 hour day today being in my pocket about 7/8ths of the time!!

I just exchanged my Nexus a couple of days ago, because of this exact issue. So far, I haven't had a single random network drop on the new Nexus.
(Tech support suggested going to a VZW store and having them swap the SIM card out, so I did. As soon as I made it back out to my car, the network dropped again. As I was walking into the Target across the street, it dropped again, so I turned around and went back to the VZW store. They swapped the phone out.)

YES. Had no problems until today (at least that I've noticed). Now its not getting any data. I get strong 4G at my house too. Right now its saying I have 3G but its not giving me any data connection despite what the icon says. Might have to take it back

I had no problem until today. This morning the network dropped out suddenly and hasn't come back. Plugging it in, pulling battering, switching all data settings (LTE/3G, roaming, etc) has no effect. I may be taking a trip down to the Verizon store over my lunch break...

There is an issue with Verizon 3G/4G data right now, it seems to be down nationwide.

I live in Arizona / Phoenix and am experiencing the same. I have no data (3g or 4g) and haven't since my commute into work today. It's frustrating. This isn't a Verizon 3G/4G data issue nationwide. My coworker next to me is using a Droid Bionic and has both 3G and 4G working fine. We just loaded up several sites on her phone. I'm starting to get peeved.

Yep another co-worker with a verizon phone also has data coverage while mine has been skipping out this morning.
That being said, this is not a scientific poll since 99% of the people posting here have GN phones. Are there any reports of problems in the other forums?

Though several articles, this one being one (http://www.gottabemobile.com/2011/12/28/verizon-suffering-another-nationwide-4g-lte-outage/) are showing that there is, in fact, another nationwide 4g LTE outage. Maybe her Bionic just switches to 3G properly and my Nexus isn't? I changed it from LTE/CDMA to CDMA and powered off and on the radio. No luck.

Thanks for that. My data just came back up and it's 3G only now and seems solid. Perhaps Verizon has taken down their LTE network to prevent phones from trying to connect to it until they resolve the problem.

I'm getting a 3G icon when I turn off LTE/CDMA and put it at CDMA only. But actually trying to load anything with data (web, Facebook, YouTube) doesn't work. No connectivity.

Yeah, Droidlife reported on the outage for ALL 4G phones. My Thunderbolt is also affected. This is one of the reasons why my paranoid self is happy that I have two phones: one on T-Mo and one on Verizon.

Called VZ, data down in Miami. Phone is heating up like a mf, good 'cause it's freaking cold here like 68

I want to live somewhere where my big problem with the weather is that it's 68 degrees. Anyway, glad to hear it's a network issue and not my phone.

Random signal drops in Baltimore as well. Especially after a phone call. On second phone and still same issue.

Here in Rhode Island, I lost all signal for about 4 minutes, had 3g for about 5 minutes, then got 4g on and off for about 5-10 minutes.
As of now i'm solid 4g with no disconnect or 3g
its probably because of that 3.7+ MILLION devices activated for christmas
be glad we don't have RIM with a 3 day blackout

Yeah, and the problem with the GNex is that, unlike other phones, it doesn't seem to have a "no 4g, only 3g" capability, so when 4G goes down, we have no data whatsoever. Older phones that can switch LTE off are able to hook onto 3G.

I was in a costco this afternoon and it wasn't working. I originally assumed it was the metal building. Nope, Verizon's network again.

[Q] Data sometimes drops altogether [Verizon LTE/3G]

Hello,
I have a Verizon edition of the Galaxy Nexus, and both my initial phone and my warranty replacement have had the same issue: specifically, they both will occasionally drop all data, be it 3G, 4G, or EDGE. Occasionally they will even drop voice signal altogether. (I've also had the second phone reboot randomly - not often, but it did when I tried to use Wifi Tether, for instance).
This does not happen everywhere, but since my job takes me all over town it happens a reasonable amount, (and notably, not with the Sprint EVO 4G work phone I have). I am based in Sacramento, CA.
My phone is rooted. I have heard that the phone may have issues with switching towers? It is able to reclaim a signal reasonably quickly once it drops, (10-15 seconds) although sometimes I have to do nonsense like switch in and out of airplane mode to force it to grab a 4G signal.
I'm coming up on my return and refund period within a day or so and would like to know if I should dump this phone for an HTC Rezound, or if this is something I can fix by installing the 4.0.3 leaked software.
Thanks in advance for your help.

I know that there is a newer base band you could try flashing, and 4.03 might also fix some of your issues, but be aware that you are pretty much beta testing new technology.
I've never had voice drop on my GNex, but I will occasionally have a drop of data. I believe in my case it is because I am on the cusp of 4g coverage at home, so sometimes it will (barely) connect to the 4g tower, and then disconnect and go back on 3g. When I'm at work and I have solid 4g coverage this issue doesn't present itself.
To remedy the situation temporarily I just switch to CDMA when I'm at home, and if I am in an area where there is 4g and I want faster connection speed I'll re-enable LTE. I know this sounds like a ridiculous solution, but I love my GN too much to return it...again, we are early adopters of new technology.
Only 0.6% of android users are even on ICS - all of this technology is very new.
I believe as Verizon rolls out 4g to more areas that currently only have 3g coverage we will see less and less drops in data (greyed out bars). Hopefully Google/Verizon/Samsung will improve on the radios, etc and make things more smooth for us.
As far as wifi tether goes, I know they JUST got it working on Galaxy Nexus recently, and it is still in beta phase, so I wouldn't count on it being bug free...I had a reboot once when using the beta 10 version, so I don't think what you are experiencing is all that uncommon.

I had a similar issue but only when I was in 4G coverage. I would randomly completely lose signal for about 30 seconds and then it would come back. Usually happened quite often..about 4-5 times an hour. I ended up taking it back for a new one and a new SIM card and haven't had that issue since.

(T-Mobile) Randomly Losing Signal

My gsiii for some odd reason loses 4G and sometimes even service. Last night when i was on a call, it dropped and the signal reflected that i was running on edge then it switched to someting that said "G." I looked at my brother's siii and he was also on edge. So i tried putting it on airplane mode however it would not go through. It's as if i never pressed anything. So i had to restart the phone and it was on airplane mode, so i took it off then about a minute and a half later i got 4G back. Today when i was browsing the web, i randomly lost 4G again but this time i continued to have signal just no data. About a minute later I got it back. About a minute later i lost it again and regained it about a minute later. I havent noticed anything else about the phone and ive had it for about a week and last night was the first time that i restarted it. Any ideas? Has anyone else experienced this? Thanks!

I'm also having the same problem it just happened to me today also and happened the other day when I restarted phone it did nothing then I did airplane mode that didn't do anything so I clicked the enable packet data off then on an item came back in hoping it's not going to be a hardware problem cause I've dropped calls for no reason and had no service or bars were showing but had no edge 4G etc

Yeah it's really weird, when I was using mt4g, it would do that randomly as well, I'm not sure if it's a phone or a network issue. Anyone else experiencing this random drop in data?

Same here I think it's a common issue with tmobile devices.

I just moved from Sprint to Tmo and I'm getting the same on my S3. It would look like i have good 4g coverage with 3 bars then all of a sudden it goes to Edge. So I have to wait for it to go back to 4g to start surfing. Edge is like 15kbps for me which is not even modem speed which is 56k. If I accidentally start surfing on Edge it seems to wanna stick to Edge until I close whats using data then it will eventually go to 4g. But when I get 4g its awesome and I get over between 6meg to 12 but only 40% of the time. I called Tmo and they said I have great 4g coverage where I'm at....ya sure.

I've only experienced outright loss of signal once, which was last night. So far nothing else has happened really. It was just odd that my phone won't even go into airplane mode until I rebooted the device.

Same thing happened to me. I was actually quite worried and about to send my phone back. Everything seems to be working okay now. No issues.

this has driven me mad for the past few days. recently I upgraded to a S3 and my dad got a S 4G (which was released 2 years ago). while we were in Costco, my S3 randomly switched to Edge while the S 4G has 4G all the time. ALso we were on vacation to San Francisco so I could experience "Tmo largest 4G network." While we were in a hotel in Fremont, my S3 again switched to Edge and back to 4G randomly while the S 4G had 4G. also the signal is not stable at all. sometimes(1 or 2 times) it even dropped to zero bar. SOMETHING wrong with samsung phones. I read somewhere someone had this issue with the S2 also. I can live with the HSPA+ for 2 years, but hey dont give me random Edge like that
I plan to go exchange for a new phone at Costco... probably a new S3 to see if the issue still exists...

T-Mobile's 4G network works in a interesting way (do all HSPA+ networks work this way?). They idle in UMTS mode (3G) until there is network activity, and then switch to HSPA+ (4G) mode. The network changing is an automatic thing does to save battery life ("Cellular standby" is often the largest battery drains).
Ever use an AOSP-based ROM (i.e. Cyanogenmod)? You'll sometimes see the network indicator in the status bar switch between 3G to H+ to 4G, etc as you use it. Stock T-Mobile ROMs are hard-coded to always say "4G", but if you go to Settings → About phone → Status, you can watch the network type there change as well as the phone does anything over the cellular network.
You should never be dropping to GPRS or EDGE. Perhaps the mechanism described is defective on your phone?

Happened again today. Had signal but no 4G, not even Edge, just bars. i think it happens whenever the signals low. Thoughts?

I'm having the same issue at my work place. I'm getting Edge (50-80%) more often at my desk, when previously with my SGS2 it stayed at 4G all the time. Checking Cellstandby I am getting 31% time without signal.
Is there a setting to force 4g connection?
My office is in Cupertino, CA and reception is not bad in general, but there are a few locations with 4G dead spots.
I'll check my reception again at home (Santa Clara, CA). I can do a side by side comparison with my SGS2 (now belongs to my wife).
On call with TMO right now, they are going to do a reset of the phone in their system, then I will need to do a reboot. Fingers X'd that things will improve.
BTW, what options do I have to get a replacement phone if I bought mine from Walmart? Do I need to send it in or can I do an instore exchange? Just got it on Sunday. Will I incur any fees if I returned the phone?
---
Reset didn't work. Passed on to level 2, there submitting a service request to check reception in the area. Need to follow-up on Friday if the reception is still bad. Since I'm in Cali I do have 30 days to return the phone.

I have similar reception issue but I dont lose signal completely. I will go from 4g(hspa+) to 3g to edge then it will switch back to 4g after 30secs-60secs. Quite annoying since I will be stationary and it will happen and it happens more when Im in a car. Never had this problem when I had the Nexus One.

Question. With your s2 what happens if you're in an area without 4g? Do you get edge?

I am having the same issue. I had perfect 4g coverage all over my town, (I live in south texas). The problems started 2 days ago, when I lost all 4g coverage. I took out my sim card and placed it back in and the 4g logo came back on. But now I have been noticing that my cell signal will completely drop and then slowly come back up. This has happened several times. I also went to tmobile and changed my micro sim card and the issue remains. AND NOW I AM ON EDGE!!!!!

Has anyone been able to get a replacement and did it fix the problem?

[Q] HTC One M8 dropping data connectivity but showing 4G LTE...

Hey everyone!
I have a stock M8 with T-Mobile and I live in LA. I'm new to T-Mobile so I wanted to ask if this is normal.
My phone will lose data connectivity but the 4G LTE sign will stay on. Spotify will stop playing, Speedtest won't work, but the phone keeps telling me I have 4G LTE.
This happens a lot especially when driving, but today it happened while I was in the drive-through of a fast food place. I had barely moved and yet data was working fine at first, then suddenly "poof" nothing works anymore cause no internet, but the phone insists I have 4G LTE.
Usually turning data off and then on fixes it but not always.
Could it be an issue of switching towers? But then wouldn't my signal drop completely? Why does only data stop?
Anyone else having this issue or do I have a lemon phone I should return?

if you are jumping from tower to tower it may not relay properly. Call tmo and tell them to do a signal refresh. call from a different phone.

Do you have power saving mode on? The reason I ask this is bc it will turn your data connection off when your screen locks.

Same here ,
Ever since I bought the m8 it happens to me time to time.
Ive tried dis n reconnect the mobile data or go on airplain mode, but sometimes reboot is quicker.
Hope HTC publish a bug fixed firmware soon

Its a provisioning issue on the towers people you need to call tmo...

This was happening all the time to me on my Note 3 which Is why I upgraded to the M8. Just got it last night and it's happened once. Also, the signal isn't as strong. My Note would hold a lte connection with barely 1 bar. The m8 not so much. Likes to switch between 2g, 4g and lte.

It was fine for a couple of days. Today however I had to wait in the car for 1.5 hours for something and was playing Spotify.
Didn't move for that entire period. For an hour it worked fine, then suddenly it did this again where it wasn't receiving data and yet the 4G LTE sign was on screen.
So I guess it didn't really help. I turned data off and on and it restored it, but still... that's not cool.

Yeah same here. It happens in my house when I'm using my phone in bed and just loses data but it still says LTE and have to either turn off and on data or reset my phone.
Also on my way to work today I was using Spotify the entire drive, which is about 45 minutes, and never lost data but on the way back it lost it about twice. It sucks and hopefully there's a fix of some sort.

I have had my M8 for a week and have not experienced any issue with data loss. I am in Miami, Fl. If anything I get way better LTE speeds than I have had with any of my last phones( S4, G2, Iphone 5S)

Same issue with my M8.
Full bars LTE signal and sometimes data just stops working. Need to reboot the phone to get it working again. Was thinking about exchanging the phone but it seems like a software glitch...

I don't have this issue but I do have terrible speeds in south Atlanta.
3-5 bars in my home, and download speeds are from 3-6 Mbps down and uplad from 2-3Mbps up even with LTE. I get much better performance on HSPA+
LTE pings are half that of HSPA though

Just to add on here, in my experience this has more to do with the area and likely the towers supporting that area then software or hardware. Another possibility is T Mobile's network in LA is not 100% compatible with HTC is new radio firmware yet. If that's the case some tweaking by t-mobile on the backend would fix this issue straight away.
The reason I say this is because in Las Vegas, Nevada I never have any problem with LTE losing connection, however, this last week I was in Long Beach, CA (LA County) and constantly had loss of data connection while the phone would still displaying a full 5 bar 4G LTE connection.
Reboot or switching to airplane mode would fix it, however, it got to be so bad and happened so regularly, I eventually stopped using LTE entirely while there. The HSPA+ "4G" connection there was still producing around 10 megabits per second download which was more than enough. So, while there I switched off LTE and had no more issues with data connection dropping.
Long story short clearly seems to be an issue with T Mobile Lte Towers in the greater Los Angeles area. Possibly its an issue in other areas as well.

Happening here in South Houston too, but i am using a VZW M8 with Tmo.

I also have this issue, but I'm on AT&T and missing some bands that I need, so I was figuring it was that.

I had a galaxy s5 and had same issue.
So i know it's not the phone
Sent from my HTC One_M8 using XDA

Has anyone found a solution to this problem yet? My HTC One M8 has been losing data connectivity ever since I purchased it last month. It will say I have 4G LTE but I will loose data connection regardless. It's a nuisance. I never had that problem with the M7. My camera on the M7 got a purple haze so T-Mobile replaced it with a refurbished M7. It was the worst thing I could've done. The refurbished M7 would freeze and reboot a lot, until it finally got stuck in a boot loop and I lost all my photos, videos, and files. Would not go into recovery. Then T-Mobile sent me a plastic Samsung S4 as a replacement for that because they were out of the M7. The new M8 has been working pretty well except for the annoying data connection loss everyday. I have to activate then deactivate airplane mode to obtain data connection again. Only other time I ever had this happen was with a certain nighyly rom I put on my HTC HD2, but that was rooted, this is a stock phone, I never expected to have a data connection problem with a stock rom.

I had this problem for ages with straight talk with my old phone just before I bought my M8. Exactly the same issue in that my data would seemingly just cut out randomly after a bit then come back later(switching off/on and/or in and out of airplane would restore it).
In my case, it turned out to be my data settings. I played around with different settings one night and found that different settings finally got rid of the problem for me. Your mileage may vary, but it's an easy enough thing to try.
