[Q] Radio quirkiness amongst different nexii (Verizon)

My nexus is a hw version 9. it had some hand off issues from wifi to data with the 4.0.2 radios. the 4.0.3 and 4.0.4 work so well i almost thought they could do no wrong. until i got my wife's nexus which is hw version 10. this one works fine with 4.0.2 doing handoffs just fine, but with 4.0.3 and 4.0.4 i get this weird signal drop every once in a while where the network goes away, the bars become a solid dark grey triangle for 2-3 seconds, then connectivity comes back and data shortly thereafter. anyone else seen this?
UPDATE:
i noticed the problem happened even with the 4.0.2 radio. also the longer the phone went without a boot cycle the more frequent the problem became. asked for a replacement and got a CLNR which is hw9 that doesnt seem to have a problem.
see post here
http://forum.xda-developers.com/showpost.php?p=23621403&postcount=15

where are you determining what hw version you have?

the bootloader for one. also the about phone says it in the radios/baseband.
the version 9 reads 1515.09
and the 10 reads 1515.10

Got it. I have version 9 as well. I live outside of a 4G area so I pop in and out of 4G coverage quite often. Personally the 404 radios are working the best for me right now, switching between 3G/4G is pretty seamless. Though I cant honestly say I have had the device in my hand, screen on, and using DATA while it went from one service to another.

yeah thats how my hw9 behaves.
im parked solidly in the middle of a 4g zone and the hw10 just loses all connectivity albeit for just a couple of seconds on the 4.0.4.
4.0.2 works fine.

I'm on HW 10 and the 4.0.2 radios work great.No issues here and no problems with dropped data.

I am HW 10, 4.02 Stock.
And my GNex has been dropping data+voice every 5 mins when I try to use 4G. As long as LTE is off, 3G+voice is fine.
I also have tried 4.04, and same problem...and came back to stock 4.02 and waiting for OTA I guess..or that's what VZW tells me to do...

I had just mentioned this in another thread, but I haven't had the loss of call audio bug since my rev 10 device.
At the same time, my wife has a rev 09 device, and never had it. We are both on 404 radios, and I only drop data when in fringe areas. I never, ever, drop voice.
charlescom, dropping LTE does not affect voice.

Consider yourself very lucky. I'm about to get rid of this phone because of it.

Adrynalyne, that is what I thought until I bought gnex.
Check out this google issue if you are so lucky to have picked a good gnex out of lemons.
This is one of major flaws that affected so many gnex users. Officially titled gray triangle of death....
http://code.google.com/p/android/issues/detail?id=24345
If you scroll all the way down, you will see all the screen shots I uploaded on exactly what a user faces as the voice and lte drops...
Thank you..

Yeah, I have never seen that before.
Weird.
Edit: Allow me to rephrase. I did have that once. It was a bad sim.

I have this issue. Stock 4.0.2. Have only had the phone for like a week and it is pissing me off

That does look potentially SIM related. The VZ phones do have a micro sized SIM card.
With posters reporting the same issue on multiple replacement phones, I wonder... was the same SIM card transferred to the next new phone?

At least at my location SIM replacement was the first thing on the list way before vzw even start thinking about giving out a replacement. And yes, I have been given so many SIM replacements you dont even know....and as far as bad batch goes.....why are there so many bad batches to begin with.....hahahahahaha...it is almost a joke. I am not even getting frustrated any more...i just laugh....lol

it was definitely not sim related. its my wifes gnex and i swapped sims with her. her phone gave me the same problem with my sim and her sim worked fine in my phone.
doing some more research, here is the findings.
my phone - hw9 - works flawlessly
her phone - hw10 - has problem
got a CLNR from verizon which is hw9 which seems to work flawlessly again.
interesting thing is the difference between the stickers on the insides of the bad and replacement phone:

the good one (CLNR hw9) is the left and the bad one (new hw10) is the right.
there is a long thread on rootz about this very issue and the conclusion is that if u have this particular problem, its hardware, go get a replacement.

[Q] Bell Samsung Galaxy S3 LTE

Hi Everyone.
I have a Samsung Galaxy S3 unlocked, stock ROM and rooted. When i used the phone with Rogers it showed 4G. Now with Bell it shows H+.
I am ok with H+ because as i understand this is very similar to Roger's 4G. However, I have never gotten LTE on my phone.
Is there a way to enable this? I have checked the APN settings and they seem to be correct as per this forum.
Any ideas? Am i doing something wrong?
Thanks
Michael

I would make sure that the sim card you have says LTE on it (happened to me that they gave me the wrong one)
Outside of that I would recommend going to a strong LTE area and try to force LTE.
to do that go to your dialer
type *#2263#
Select LTE then LTE All, once you catch on to LTE go back into that menu and select Automatic

Have you confirmed your network speed with speedtest?

Thanks for the responses.
y2whisper: My sim card doesn't say LTE on it. It's a nanosim card that i had from my iPhone 4S. I was told the same sim card would work perfectly. I also tried that in the dialer and I selected LTE. It disabled my data and eventually i lost signal, no LTE signal came on. As soon as i put it back on automatic, it connected back to Bell with H+.
mrhaley30705: i did a speed test. It registered my download speed at 4757kbps and upload at 2398kbps
How does this fair?
Thoughts?

I was originally given the wrong sim card as well. Took a couple days to realize it. Went back into Best Buy where I got the phone and had it replaced. LTE fired right up. As to your speeds, depending upon your location, you could possibly add a zero to the end of those speeds and that's how much faster LTE could be. Here is mine but my area doesn't have the best LTE speeds.

Bell uses different micro sims for lte than the one you used for your 4s. Bell stores sell em for 5 bucks, but you can usually get them to give it to you for free.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

yeah it would work perfectly minus the LTE ability. yeah get a new sim and call bell. Some bell stores try to charge you a courtesy fee to activate it. don't pay it.

thanks everyone for your help.
Switching SIM cards did it. Now instead of 3000-5000kbps on 3G i am getting LTE speeds of 30000 - 42000kbps.
Thanks

I bought a Bell S3 I747M and unlocked it to use on Fido, had to use the right APN settings plus using this trick to get it work.

T-mobile lied to me

I have been with T-Mobile in Bloomington, IL for over 7 years now. The only thing I have ever complained about is data speeds in my area. So, when I read the following press release from T-Mobile last year, I was super excited.
http://newsroom.t-mobile.com/articles/new-4g-markets-nov2011
In that release dated Nov 16th 2011, it says
"T-Mobile 4G markets where HPSA+ 42 service is launching today:
Bend, Medford and Corvallis, Ore.; Benton Harbor, Mich.; Bloomington, Champaign–Urbana and Springfield, Ill.; Columbus, Ga.; Hagerstown, Md.; Montgomery, Ala; Yuba City, Calif."
So, I have not seen a difference in speeds at all over the past year with the following phones, HTC Senseation, Galaxy Nexus GSM, HTC One S and the Galaxy S3.
I have never gotten anything above 3Mb anywhere in town. Now, when I call T-Mobile to inquire about my slow speeds, they tell me only 3G is offered in my area and that the speeds I am getting are consistent with there network. FYI my status tells me that my Mobile Network Type is HSPAP:15
Attached is a screenshot of my typical speeds. Am I getting ripped off on data speeds?

Guess you better switch to Verizon.

Id love to see your speeds. Im on edge.

Could it be that half of Bloomington is covered but the other half isn't, and you're in the bad half?

I would call customer service and politely ask to speak to tech support. Let them know your issue and ask to speak to a supervisor. When the supervisor gets on the phone tell them you want this to keep getting escalated until you get an answer.
I had a similar problem and it took two weeks to finally get anywhere.

I have though the same thing, but Bloomington is a pretty small city and I have driven all over town doing speed test in the past. Plus, when I have called them, I am told that there is no 4G anywhere close to me. Does that make sense if my network type is HSPAP:15?

Your speeds are up to par with what I get. Hell they're better. I would say everything is normal. T-Mobile has very weird and spotty service. I'm hoping the reframing of the towers will help.

Honestly you shouldnt be seeing much of a difference from people downloading at 10 Mbps... you're still downloading at 100 KB/s with 1 Mbps....

Your problem was completely different. You had towers down in your area.
OP, you need to realize that every single phone you listed aside from the One S and S3 are NOT capable of HSPA+42. So that is your first problem. The second problem is that wherever you are in Bloomington, an HSPA+42 tower does not reach you. Coverage isn't always the best. I'm a five minute walk from Wrigley Field and a five minute drive to downtown Chicago and I only get 7-8mbps. I drive fifteen minutes west to where I went to high school, and I get speeds of 20-22mbps.
Third, HSPA+42 speeds are THEORETICAL. You can THEORETICALLY have speeds that fast. You aren't guaranteed to.
Also, HSPA+42 is still 3G.

It looks like you encountered massive traffic or the backhaul is not upgraded.

I had the same problem. I kept upgrading phones, buying them full price so I didn't have to renew my contract but I just kept switching my old SIM card into my new phones. When I switched to the Sensation I called T-Mobile about my slow speeds and they told me I had to upgrade to a "4G SIM card" and that worked. I would say that could be your problem but being that you now have the S3 and it has the micro SIM card then maybe they didn't upgrade your area yet.

That sucks dude...I'm out in Orlando, FL and I usually get about 10-15mbps almost anywhere...
At home I get +15mbps every time...
I attached a photo with the difference of my WiFi at home and my HSPA+42 at home. These were after a ROM change so I only have 5.

Do you notice the same speeds on other speed tests or super sluggish browsing?
It's possible to imagine that the nearest and even lowest pingable server is simple not responsive to your (up/down)link. I usually compare to freespeedtest.com and even grab files from local servers.
Also you server's routing table could be weird.
If not, I'm inclined to believe that it is an overhead problem.
Go to the phone dialer (on stock) and try doing
*#197328640#*
1:UMTS
1ebug Screen
1:Basic Information
And check the bottom item lines. You should see some connection information about your service. Can you list what you have?
Also, jic check the Band at the top and make sure it says 4. Possibly could be defaulting to 1900 experimental.

Data Profile settings questions

Just want to ask a few quick questions before I go poking around too much in the ##3282# settings. I got my MSL code and have been looking around in the settings windows. And a few of them made me wonder.
The first is the IOTHiddenSettings menu. It list all the various modes of the phone. Its currently set to "LTE+CDMA+EVDO mode". I'm assuming this is the best mode vs LTE Only Mode. That mode would probably keep me from having service since I dont live in an LTE area atm based on sprints latest coverage map. But what about the "hybrid mode" or the "global mode" options? Will those give me something faster than 3g? Maybe let me roam onto a local LTE network like AT&T's?

Next is the APNs list. I'm just curious if its really set for the best one?
My ultimate goal is to get this phone to stop having such a slow connection while away from wifi. I swear this thing feels like its on dial up at times. And I'm standing in a place that I know should be getting speeds a lot better than 21kb/s. Such as downtown Baltimore. Or the national mall in DC. Places where I've got full signal strength and would expect a network that could handle better speeds even with a lot of people.
GSM must be a different animal. Because with my AT&T iphone, I've seen it show 3g, 4g, and LTE. I tend to get 4g in most places. 3g happens when I'm going way out. Like Harper's Ferry, WV or somewhere similar. LTE happens everywhere in the city.
Why can't this note 2 get that kind of speeds on sprint? I don't remember their network being this bad in the past.

Depending a your location, sprint might be be working on the 4g LTE, so it might be causing slower data issues since they are working on the towers, the trick is, they work on those towers batch by batch and chances are there would be a better working cellsite in your neighborhood...u can ##SCRTN#, enter ur msl code and the phone will reprogram itself, while doing that, it will be looking for the nearest best signal, so u might lock on a better tower. As per the "Hybrid Mode" i believe its a network mode for 3g CDMA and the 1X EDVO...if you do not have 4g in area, i'll recommend sticking to cdma only, as for the APN, you are on the best one available in ur area right now...

Question anyone have issues with T-mobile data?

Despite me having bars per Android, almost max, I am getting horrible internet/data connection. Can't even browse a website. I tried switching between 5g/LTE and makes no difference unfortunately. Anyone else?

t mobile usa in Houston Texas not problems at all

Mine was quite a bit slower than my Note 20 Ultra at first but after a couple reboots it's almost identical to the Note.

No problem here with Magenta Max. I got 470Mbs the other day on 5G UC (ultra capacity).
Any chance they are throttling you?

I am here in NE Ohio. At times it crawls so bad. Really pissing me off. 5G to LTE handoff is horrible

I'm having problem when it shows 5g UC. I get no data at all. If it shows just 5g it's fine. I have to switch to LTE when I have 5g UC or I get no service.

i thought that was the issue too. i will say LTE is better than 5G but both are bad compared to other phones

I was on the phone with them today, no luck. They are clueless.
Horrible 5G and LTE.

I had good speeds when I 1st received it. Think my issue started with last carrier service update.

Same here. The first and maybe the 2nd day it was very good for me.

T-Mobile here. 5g in my area in San Francisco (in the middle of the fu_king city) is total ****e. The worst is the P6P (and my 4a5g) refuse to let go of a weak, one bar 5g signal for a much stronger LTE signal. I turn off 5G more than anything on this phone.
I can't say blame falls all Google or all TMO. All I know, is it ain't pretty when you are trying to save the world from the Enlightenment (Ingress reference).

T-Mobile was upgrading a tower near my house a few weeks ago and I had the same issue, pre Pixel. The P6 Pro has been super fast since I got it. I'm using the unlocked version straight from Google and not the T-Mobile version.

Yeah T-Mobile has been trash in this phone. No matter where I am I can't get over 3megs. When my iphone gets 20+

mine was all jacked up too. did a reset of all network connections in settings and rebooted and it's been great since. it was fine for the first 2 days as well. carrier services update may have messed things up.

same here, tmobile is not great, same issue on 5gUC, will get around 1-3 down which even then freezes and loads any video playing and music will just stutter. so its been greeaatttt

I uninstalled latest update to carrier services from the Google playstore. I can at least get data now on 5G UC.

I'm on T-Mobile by ways of an acquired Sprint customer. I'm in Tampa with my 6 Pro on an eSIM and data service has been very good. 5G symbol everywhere and 5G UC speeds are faster as I've been speed testing when I can and see it.

Well that was short lived. Took the dogs for a walk this morning. Back to no data when on 5G UC. Getting the exclamation in the notification area.

My 5G on TMobile is good so far, but it depends on the Tower locations...
