Data transfer speeds

I'm not sure what is going on with my phone.
Since the 16th of January, my phone's data service appears to have crashed out.
Prior, it was working fine. I was running an old version of Perception with Firebird, and Phoenix with Firebird (2), using the I9000UGJL2 modem. I got ~~5.0Mbps down, 1.6Mbps up consistently on HSPA, and the more meek 3.8Mbps down, 1.5Mbps up on UMTS. Both times around 100-250ms ping.
All of a sudden on the 16th, my phone has now hit the crapper. Speedtest no longer reports me at my location (instead in either central Florida or northern Texas). On the download test, the dial will slowly rise to .06Mbps, then on the upload test either just not work and flash a token gesture .1Mbps or sit at 0 and then do a rapid bounce back and forth between ~~3Mbps and 0, usually reading at one of those extremes. My ping has also skyrocketed to upwards of 600ms for no reason. This is also indifferent to whether I'm using HSPA or UMTS.
Since this time, I've flashed several different modems and several different ROMs. All produce the same result, as does CWMing to some really old backups. I have mastercleared in between some of these, but it has done nothing.
I know it's not an error with the Speedtest app, because I can still do it on Wi-fi and it'll read as my home PC reads. My phone's internet browser reflects the same cause, taking upwards of 20 seconds to load Google mobile.
Anyone encountered anything similar or can explain why? The slowness is becoming inexcusable, and I can't use my phone on the network anymore for internet. I have to leave it on Wi-Fi to my disdain. At this rate, I'm leaving ATT the moment I'm given the chance. I'm not even close to going over my data allotment, so I don't really know what could possibly account for this.

att is in the middle of updating to 4g. Some more terrestrial areas are going to be sol fire a bit sadly. Where do you live?

Bridgewater, NJ. But this happens no matter where I am. Even if I approach NYC, it's still crap. I can't tell whether this is a network cap issue, a "phone is broken" issue or a "network is bloody awful" issue. It doesn't seem to be terrestrial, because I've taken it to Philadelphia and NYC and both places have been awful. Meanwhile, going out into the more rural bits still puts me on EDGE, which still yields the same reading (but that's the norm for me on 2G networks).
The key aspect here, I think, is that the readings are EXACTLY THE SAME regardless of the network mode that I am in. It's really confusing me.

I've noticed a determent in my speeds and ping as well. Before, I used to be able to get 3.5+mbps down and 2mbps up with 200ms and now I struggle to get 1mbps down and always end up with 1.5mbps up. In real world, it's more like 300kbps down and 300kbps up :/
I shouldn't be complaining but I live in the DC-Metro area and this determent has been getting WORSE for about two or three months. My ping right now is 600+ms and Speedtest NEVER catches my location right, it keeps saying I live in Kansas.

Have u tried manually changing the server on the speedtest app? I get better ping results from a server that is 600 miles away than a server that is 80 miles away.. just wondering :/

...Of course. lol That's the first thing you could do to improve it. AT&T Is shipping me a new Captivate (sucks that I have to reinstall all my apps on it :/) and i'm getting it by tomorrow. I can verify if it's a device problem or AT&T's network since I could assume if i'm having the same symptoms as OP and it's fixed by a device exchange...
Then the way to fix this problem is a call to AT&T (ask to be transferred to level 2 support)

Done it with my 2 local servers, the Kansas server, the Texas server, the Florida server and the Sydney NSW server (the last via my MobileAP tethered computer).
All the same uber-slow reading, ping generally gets worse as I go farther away. Nothing really out of the ordinary.

Have you considered it might be your modem? It really sounds like it's connecting via EDGE or even GPRS o_o even when it shows a nice pretty H or 3G in the top right corner.

I came on XDA to talk specifically about this also. I am near the NYC area roughly 35 min north and my HSPA speeds have dropped and thought it was my phone crapping out on me. Speeds have lowered similar to the OPs post and I am guessing it is because of the new towers they are putting up since how drastically i've lost bars I tried switching basebands and making sure i'm solely on 850 and 1900 and also tried 850 alone. Well i'm glad it's not only me =] i'll keep you posted if it fixes itself.

As said in original post, I've swapped through several modems and several masterclears. Both dialer codes and phone status show that I'm connected to the right networks relative to what it shows in the corner.

I have also, when did your problems start btw? mine have started today with the speed issue.

I had this issue a few weeks ago. I got a new captivate, and after a day of use it happened to my new phone. I called again and was sent to a store for a new SIM card. Problem solved. My SIM card was from 3 years ago, and I don't know how many phones. I thought they couldn't go bad, but that fixed my issue, no problems since.

It happened to me also when I got a new captivate and tried using my sim and after getting a new one it worked flawlessly but this situation is different. I keep running speedtest and i'm getting erratic speeds sometimes i get 2mb/s down and then other it's barely 60kb/s, I feel like it definitely is a network issue near NYC. Only time will tell what it really is.

I have a new SIM from my phone's activation because my old one looked like there was quite a bit of wear on the contacts (4 years old, mind you, from the dawn of ATT's mainstream 3G release)... If this keeps up, I'll try to pester them for a new SIM again.

I have been having speed issues also but not sure it's related to your issues. I loaded Cog 3.03 on my phone to try it out. Prior to the load I was getting 1300 - 2500 up and 154 - 386 down. After I loaded Cognition it dropped to about 84 up and 40 down. I was going to go back to stock but thought I'd give it a try for a bit. It has slowly gone back up. Last night I got 2928 up and 314 down. The last 3 tries were all over 1300 up and 300 down. Not sure if it is phone or network related but I'm going to keep watching. Just tried a speedtest and got 1061 down and 73 up but I'm also on the 1st floor in the middle of my building. I'm going to let it go for a few days and see if I need to try tweaking anything or if the speeds settle out some. So far I'm pleased with Cognition. Thanks for the dev work.

I noticed all the 3g towers near me recently switched from 1900 to 850. Could it be that your non-us modem doesn't handle 850mhz band well and internally switched to edge? With stock modem, I can barely reach 200k upload speed.

That could just be your phone getting "used" to ATT's network. I remember, when I first activated service with ATT, it took a long time for my phone to authenticate with the network, gradually shortening over time. Working under the assumption that you're doing this in Kbps, those speeds are actually disgusting. Your down speed is ridiculously low, and your up seems so variable. I think it's beyond a ROM issue; I've never experienced significant differences in ROM use and download speed, except when I first upgraded to HSUPA.

Nope, don't think so. I have GSM radios disabled on my phone: I forced WCDMA only via *#2263#. Forcing WCDMA 850 alone still produces the same result. As I had said, even after master clears (forgot to mention via OCD to JF6), I still came up with these lousy readings. Checking radio status via *#0011# tells me most of the time that I'm on 1900, so...
As an update to the situation, I've permanently switched to I9088ZNKP1. Still no change, other than marginally better ping. As this is nearly marking a week, I'm becoming very tempted to just drop ATT a line and ask them what the hell is going on and how I can fix it. I refuse to send my phone back though, proud 1007 owner, and the phone is in impeccable condition. Though I doubt they'll be able to help in any other capacity since us blokes here on XDA don't seem to be aware of what's going on here.
EDIT: Just got off the phone with ATT, surely enough they could not come up with a reason or an explanation; they removed and reinstated me on the network and still no change. Ah well, time to CWM backup and OCD back to JF6. Bringing my phone into the store.

Download speed under 1.5 MB/s?

Before I begin, I already have the latest updates and everything on my phone. Also, all tests were done at full bars connected to HSPA+.
As stated in the title, I have never gotten over 1.5 MB/s in a Speedtest. I tried my phone out in 10 different parts of my city today (San Jose) and always stayed under 1.5 MB/s.
What could be causing this issue? The SIM card I am using is from an old phone (like 5 months old, was from a Captivate), could that be the reason why? The AT&T rep said that is the reason, but I don't know if that is fully correct, since HSPA is just an installment to 3G and it isn't real 4G like LTE is. So it should work, right?
What other troubleshooting steps should I take?

That's better then me, I usually get below 1mbs.
Att network just really isn't all that great, and they could also be working on the network in your area as well.

I got higher network speeds in the same areas using my iPhone 3GS!!! I got around 2 MB/s using my 3GS, and it just seemed to drop once I got my Inspire. My speeds have always been this low for the Inspire.

It will also depend on load on the network. I average 1.5 mb/s but late at night early morning i get better then 2 mb/s. Ive seen people post better speeds then that but haven't seen them myself personally. To many things could be playing into this. But i don't think its the phone or sim. I think its ATT.

Just got 2890 kbps down with 345 kbps up. Ping was 169ms. That's a lot faster than anything I got with my eXpo.

I said "**** mobile data" a loooong time ago.
WiFi all the way, baby.
Between trying to figure out whether it's the phone, the rom, the radio, the ril, the build.prop, the area, the flock of birdies flying over head, or just good old ATT, you'll go nuts.
It is what it is.
Ideally, what you need to do, and it may not be possible for you now that you have the inspire, is test out your old phone, or at least borrow somebody's of the same model, side by side. Or another inspire, side by side. That'll at least answer a couple potential scenarios.
Get your SIM swapped at ATT. I've done that and it solved some issues. Sometimes they get goofy and need to be freshened up.

Anyone else noticing HTCs losing 3G/4G speeds?

I sell vzw for a franchise/premium retailer and I have noticed on my phone first and then on everyone I know/see that has htc's I've noticed that even down to the incredible, incredible 2, and of course the thunderbolt. I honestly haven't checked the rezound but plan to if someone buys one or I have time to test it.
Basically 4G only gets under 4 mbps and 3G phones only get 3 mbps and under. Sometimes averaging around 1 mbps.
According to HTC its a network issue. I said,"how could it be a network issue if the other 4G phones like the Motorola's more specificly like the bionic I have next to my thunderbolt is running 14-18 mbps!"
Verizon says its not a network issue and I was right it is pretty obvious. They said it's a phone issue and it's the first they've heard of it.
I personally believe it has something to do with the back cover antenna. And I also can't help noticing how cheap they are and how they seem to be trying to get rid of more lately. Yes it can very well be because its almost a year that its been out and I'm sure there's somewhere I'm not looking where it shows its planned life time.
I just want to make sure there isn't a software issue going on here or if its a hardware/"dare I say it, defect" with these phones.
Now I will say I have this verified by people I know that travel through and/to Pittsburgh for school and work. It does appear that with more towers downtown u do get a lot of signal bombarding ur phone and they pull about 8mbps. Bionic was going 14-18 mbps all over my area and would imagine it stays strong in the city too.
I'm running cm7 and I got friends running all kinds of roms for there thunderbolts all same results and unrooted users/store phone sent straight from htc/random traffic in the store all get the same bad results. Hope this helps and comments are a must please.

Could be a radio issue I am still on MR2 ota this was done side by side with a Rezound at VZW store and both got similar speeds. And this is one of the slower speeds I have ever got as well.

LTE 4G Rezound

I had my TB since March of this year, and I didn't have 4G to pick up until they expanded here. While my phone would originally pick up 4G, it stopped picking it up unless the signal was very strong, like in a Verizon store where they have the repeaters. My wife's TB would pick up 4G if it was anywhere around, and would smoke my phone for data speeds every time. I had changed the SIM card, which had no noticeable effect, and finally sent it back under warranty and got a replacement. Of course, I had to unroot and restore to stock, but my replacement is as good as it should have been all along.
To the OP, It may be a situation where you have some HTC phones that have poor signal issues like mine had. My original TB could have had the issue all along, but I was not aware because of how well the phone handled everything else, and the fact that it DID pick up 4G, just not very well.
---------- Post added at 06:28 AM ---------- Previous post was at 06:18 AM ----------
Oh, to add to this, my old TB would only get data speeds averaging 4-5 MB/s down with 4G, and my wife's would get 17-26 MB/s side by side. My replacement gets 15-17 MB/s down and 8-10 MB/s up with the 906 radio. Wife's radio is 508/510 combo, I believe.

Two things I've noticed on my phone.....one is all gingerbread roms with any radio i have tried slow my speed way down except the latest shiftao5p, its decent with it. With gingerbread roms i only get about 3-5 mbps but with any froyo rom including the very first build i get at least 15mbps.
Secondly, i bought a cheap extended battery off eBay and the cheap battery cover has a cheap antenna in it. It wouldn't pick up 4g most of the time. I put a small piece of aluminum foil on the antenna prongs and put the cover back on and that helped, it would at least pick up 4g after that. With the seidio battey and cover it picks up great. So watch hose cheap extended battery covers.

The speedtest app everyone's been using seems to have inadequate test servers. I routinely get ~15Mb/s from them. Using http://speakeasy.net/speedtest, I frequently see TWICE the speed. Let me upload some screenshots from my phone. Not sure if there's "proof" that it's from my phone though, but rest assured, it is. My home 'net speed is 6Mb/s so it ain't from that connection !!

Try different 'locations' from the Speakeasy site too.
FWIW, the 33Mb/s is the highest I've ever seen myself.

Yes, in fact just last week I got a Certified Like New replacement for my TBolt for this very problem. It was resolved immediately with the new device.
I had tried replacing sim card, replacing back door, replacing battery, flashing various roms and radios, and a full restore to stock with s-on; nothing worked for the defective device.
My 4g speed degraded gradually over a period of a few weeks and became dramatically worse and practically unusable in a span of a few days at the end of it.
When I got my CLN, I had both the replacement and my original unit side by side in the same spot in my house and ran speedtest on the same server using 4g, same sim card, same rom (Stock GB MR), same radio, no SD card, no installed apps.
The difference was black and white, the original was total **** (several times failing to even complete the test due to "network issues") and the replacement was hitting ~25Mbps down.
Long story short, the TB 4g hardware can spontaneously start to fail. It's for that reason I'm contemplating getting insurance once my mfg warranty wears out. I love the character of this phone but I think some of the engineering behind it might be third rate.

Have to turn off mobile data 2-3 times a day

I have had internet connectivity issues that get cleared up immediatley after i disable mobile data and then re-enable.
It happens when i am in a solid 4g area sitting in the same place surfing the web and my data will just die. and it comes back right up after i disable and re-enable my mobile data.
it also happens when im on the bus going back and forth between 3g and 4g.
is this a normal droid charge issue?
seems like it craps out after about 10 min of surfing every time i remember it happening.
i had this happen when i was stock, after i rooted stock, and now on tweek 2.0

Had that issue yesterday on 4G, and it cleared up the same evening. Occasionally will lose data connectivity on 4G, even with it's still showing the connection. It's not very frequent or consistent, and it seems to have gotten better over time. There is definitely some flakiness on the radios on the Charge. A friend was sitting right next to me on his Spectrum yesterday and wasn't having any issues. I think it's likely related to Verizon network, but I think some phones are more sensitive to it than others.

Yeah, happens to me too. I had to disable/re-enable data at least twice today. :/

hmm.. i did have a few sim issues when i got the phone a week ago, after loading a rom the phone said there was no sim inserted or there was a sim error cant remember which.
maybe swap the sim tomorrow to see if that helps.
sounds like it might be a charge radio issue... i am getting what ever killer phone comes out in a few months anyway. Galaxy s3? HTC one X ? Galaxy Journal ?
Motorola hd ?

re
So i got a new sim..
Nothing has changed.
I have netflix and live in a great 4g area and still have to toggle off data 2-3 times a morning on my bus trip into seattle.
It seems like the radio has a hard time figuring out wtf to do once it comes in and out of 4g. I can be sitting at in traffic for 5 min with no signal and flipping the data on and then off... BAM 4g is back.
This makes for annoying netflix / IT Crowd, viewing.
I am glad that i got this phone as a temp solution cheap from craigslist. Motorola Droid fighter or Galaxy S3 will be putting this lump of mediocre electronics to rest in the next month or so.

What radio is installed on your phone? To find this out go to settings/about phone. The baseband version would be your radio. If it says i510.06V.FP1, that means you are on the most up to date radio. I had similar issues before I updated to FP1 but since then, the 3 or 4G has been very quick to connect and stays reliable all day.

One of my buds works for Vzw and he told me that the 4g network is great when it works. In some places vzw is activating 4g network before the network is ready to be deployed. They are doing this because competition has more 4g coverage.
One solution is to set your phone to 3g only and accept reliable slow sppeds or deal with crappy 4g. Eventually vzw will get it right. Wjen though, is anybody's guess.

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 posted well before your thread, but in short......theres an update being pushed that addresses 4g issues

Very cool. Thanks.

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).

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.

I feel like a tard aadmitting this but I can't figure out how to do/find step one

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.

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 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.
