Ugh!! I'm about to throw this Vibrant against the wall!
First off, I love this phone! The display is brilliant and battery is one of the best i've had on a smart phone. But I've had one issue that is driving me crazy. Lemme give you the timeline.
1) I bought this phone on the first day of release in June. Loved it! Didn't have any issues.
2) Soon after the 14 days were up, I started having data issues. At first, every so often, whenever I would listen to Pandora or Slacker, after awhile the data connection would "freeze up" and I couldn't connect to the data network. I could occasionally resolve this by rebooting the phone.
3) After awhile, i noticed that the problem got worse. Any data-intensive app or website would cause the data to "freeze". It would be random. Sometimes, I could listen to Pandora or Slacker for hours or sometimes after 5 minutes it would lock up. Rebooting would sometimes work, but usually not. It would just resolve itself, but usually after 30 minutes or more.
4) Now, its basically happening all the time. Even trying to browse to google.com causes data to "freeze". Downloading anything is next to impossible.
I put "freeze" in quotes because i'm not exactly sure what is going on. The notification bar shows 3G with full bars. Knowing that is not always a good indicator, I downloaded mobile signal widget. During these periods of "frozen" data, it would still show 3G or "H" with signal anywhere from -63dBm to over -100dBm. Yet, no matter what, I still cannot connect to anything over the data network.
I've factory reset, reflashed stock, upgraded to JI6 (and JI2 prior), flashed Frankin-Twiz, flashed Bionix, flashed different kernals, no dice. I contacted T-Mobile and they sent a replacement phone. Same issue. I contacted Samsung and they had no idea what it could be.
Please. Can any one of you geniuses help me out? I'm considering going back to my trusty G1 (which does not have the issue), but I'd rather not.
i had similar problem on mine, before the JI6 update. I spent many hours on the phone with Tmo and no success. I had found that rebooting the phone seemed to restore my true data access, but you shouldn't have to do that 5-10 times a day. Eventually they turned on the "Android Web" at a cost of $10 extra a month and then it was less spotty. I don't know what eventually fixed it but it now works so much better. Then JI6 helped out a bunch too. I think somehow rooting it helped, but I don't see how. It doesn't make sense. My best guess is that Tmo signals suck or go down frequently and a bad factory modem points that out more clearly?
Well, I've always had Android Web (at least for the last 2 years), JI6 seemed to make it worse, I've been rooted from almost day 1, and all indicators show that the signal is good.
If I were to have to reboot everytime, it'd be much more than 5-10 times a day.
I would think at -63 dBm you'd have terrific data speeds. Best I've ever seen on my Vibrant here in Dallas is -81 dBm. Even though the notification icon said "3G", in the about section it showed HSDPA. I then ran a speedtest and was averaging 5 mbps download which is fantastic compared to what I get at home. I'm lucky if I get 1 mbps at the house and that's if it doesn't stall out requiring me to force it to 2G. I normally average between -81 dBm to -97 dBm, sometimes over -100.
But my phone has never frozen or anything like that. There have been occasions where the green up arrow will stay solid and I won't be able to use the data. But I think that is due to 3G being kind of ****ty near my house. I never have that problem if I force EDGE.
I am still using the JFD firmware though. I have yet to receive an OTA update and nor do I care. I also don't really care to flash it with ODIN either at this point. I'd rather wait until 2.2 is released....not holding my breath for Samsung/Tmobile though. I think TMO's 3G just sucks in a lot of areas. I have a Blackberry 9700 which gets similar crappy 3G performance. Case in point, I was at a wedding last weekend 10 minutes from my home and coverage was awesome. I never knew what decent HSPA was until then with this phone.
Oh and regarding the battery....while the SGS's battery isn't terrible for a smartphone, it holds nothing...I repeat...nothing...to the Blackberry. Sorry, just had to.
What I am about to say is very unscientific and 100% placebo based. Here goes:
I have always had that same problem. When using the extended battery and backcover, however, it appears to be nonexistent. Using speedtest I am getting upwards of 5 mbps where I previously would only get under 2.

Isn't the antenna on the bottom of the phone? Hence the so called 3g death grip. You may be on to something I switched to a different case....the fake carbon fiber samsung with galaxy s on the back and it seems my reception isnt as bad as it was. I dont have to force 2g as much at home. Previous was the casemate tough case. Either that or I'm just holding the phone differently. Or its a placebo affect like you said.
Anyone else have any ideas? Does that logcat help at all? I get a feeling most of the people who know the intricacies of Android don't look at this forum.
Oh boy oh boy....
My TB has been giving me some issues lately. Notably, data issues. Starting Sunday morning, it would not connect to 3g or 4g. No matter what I tried. Reboots, battery pulls, Fix permissions through Rom manager, turning the radio off and on, Airplane mode off and on, 4g only, 3g only. Nothing worked. I was running the MR2.5 Radio with Das BAMF 3.0 RC4. So I flashed the MR1 radio and put CM7 on it. That worked great. For a day. Starting this morning, it started doing the same thing. Will not connect to data.
When I say that it wont connect, I mean it will not send or receive data. In the "about phone/network" menu, it will state that it's connected to LTE or eHRPD (3g), but it will not send data. Ping tests fail. Nothing goes through. Texts and calls work fine over 1x, thankfully. So what do I do?
Also, when I try switching to 3g only, it gives me an error that phone.android process has stopped working. Then my radio goes out completely, til I switch back to CDMA only.
Does this have something to do with my phone flying out of my jacket pocket while riding home from Milwaukee? I was cruising at 70, listening to music, then BAM! No more music. Check my pocket, phone is gone. I pulled over to the shoulder, got out, and walked back to find it on the other side of the 3 lane highway. The battery cover was about 40 feet away. Aside from some scratches on the kickstand and the ring around the camera lens, the phone appeared unscathed. It worked fine for 2 weeks after that too...
Should I call VZW and see if they can replace it? Revert back to stock and bring send it in?
:help:
maybe try and get a new sim card first.
Well, 4g works now, but I'm barely in a 4g area, so it's spotty. 3g will not connect no matter what I do. I have tried a few different combos of Radios and ROMs, to no avail. Does anyone have any suggestions?
im having problems here too im on rc4 3.0 with new ota radio just this morning it srarted acting up im stuck on 1x im in,mesa az

I would pull out the SIM and just make sure there's no crud in there. Slim chance, but checking the md5 of the radios before you flash just to rule that out. Other than that, I can't think of anything. Isn't there a diagnostic you can run on these?
ok guys im trying again im still having the same problems as OP everything works fine over wifi and 4g is a little spotty but pretty stable for the most part and i didnt have issues till i went to the newest radio i have done just about everything and i mean everything battery pulls flashing, recover and evan go to bone stock and i did manage to get 3g working again but then 4g wouldent connect and evan than 3g was not that stable so i personally think the radios are some how damaged from radio flashing anybody have this happen to them
I'm also having this problem but I'm.using CM7 1.2 with the MR2 radio I get 4g but when I go to web pages it won't load if I switch to 3g only the pages load. this is really pissing me off because I call Verizon and let them know about the issue and they say nothing is wrong even those they say they are receiving many calls about the problems and try to trouble shoot me I'm not stupid I know more about this phone then them. Btw I also tired mutliple radios and roms and still no lucky I'm in Houston Texas
I do not think its a root or radio issue. I have Th3roy on mine with the leaked radio its got no google voice or browser on 4g, 3g is fine. One of my buddies ahd two non rooted tb's they're both doing exactly the same thing.

call verizon beacuse you are not the only one i posted the number in the 4g issues thread already this is pissing me off because i tried many roms and radios and no luck
you probably ruined the connectors on the battery cover. theres some little gold tabs on the back that connect to the phone and act as an antenna. before you try anything else i would try getting a new battery cover. also try pulling out your sim card to see if theres anything blocking the connectors.
Verizon is having some techs check their end of things. They want to see if there is a problem with their network before they send me a phone. I pretty much know it's not the network, as nobody else is having this issue in my area, and I've traveled outside of my area with the same issues. I guess I have to wait patiently until they decide to replace my phone.
I have no issues when i switch to CDMA Auto PRl, I get zero 3g drops in data.
However, when i have it set to CDMA + LTE I always get 4G and 3g drops in data.
Whatever the problem is, they need to fix it, its getting ridiculous not being able to use 4G all the time.

Rooted Rezound, on latest released (from VZW) RUU.
Every so often, the data arrows go away, and I temporarily lose connection and have to wait a few seconds for them to come back. This happens when I am stationary, moving, in different areas, here, 100 miles away, different times of day, in stock apps, in the home screen, in 3rd party apps, etc. Wifi on, or off. Tried pulling battery to reset, still happens.
Is my only choice a wipe/factory reset? Could it be an app running in the backgrond, on startup? Any types of apps I should look out for? Everything I've installed came from the Play Store.
I was pondering giving this an excuse to try an ICS rom instead of waiting untill VZW for theirs.
What area, sir. I am in the Myrtle Beach area and it also has been intermittent.
Also, check the sensorly maps to see where Verizon LTE has been tracked.
Chicago area. The bars stay, but the 4G Data Arrows go in and out. Can't seem to figure out a pattern or rhyme or reason for it.
So the arrows aren't lighting up or the whole 3G/4G icons disappear? The arrows are part of those icons so the arrows can't only disappear the whole thing would. When you did the RUU did you do a factory reset in bootloader? Usually a factory reset there after you do an RUU helps with any connectivity issues.
Sent from my Sense4 ICS Rezound
The whole 3g/4g Icon with the arrows and all disappears, causing whatever would be to the left of it to shift to the right.
Yes, did do factory reset when I flashed the latest RUU when it came out months ago. Also this only started happening a few weeks ago.
Sometimes mine does it too but it comes back within seconds never had a problem were they didn't come back. It could just be the areas your in the signal getting lost for a bit.
Also it has happened before on other phones too not just the Rezound
Sent from my Sense4 ICS Rezound
Yeah, they do come back after a moment. Just never noticed it this often before, sometimes it happens 3-4 times in a row. Very annoying when needed to look up something.
That's weird mine only happens once in a while could be bad signal in the area or could also be your battery cover. Maybe its loose and the points aren't touching all they way or dust is in between them. Try cleaning the battery cover use a old toothbrush or compressed air and clean off the metal points and see if that helps.

Same thing was happening to me starting about a month ago and I started a thread:

[Q] 4G cutting out since 6/4
I actually did some diagnostics with tech support (level 2 I think) and he confirmed that my roaming capabilities were outdated on my SIM. We tried a few things and I ended up swapping out my SIM and my signal has been a lot better...worth a shot.

Sound pretty normal to me.
This has recently been happening to me. I only use 3g. But this past week in Wisconsin area my signal has been completely diassapearing for 30 min or so. I have to turn off phone and turn it back on to get signal back. I'm from nh and traveling, I am guessing that where I am has spotty coverage, eventhough I have 3 signal bars on 3g

Was in-store the other day, mother was upgrading to the Samsung Galaxy S3. Customer next to us came in with the same exact issue I have.
One of the VZW employees recalled a similar issue with the Motorola RAZR right before ICS dropped for it, and the manager and told us that we should be getting the ICS update about the first half of August.

This seems to happen when I go from an area with a good 4G connection into a subway tunnel or an area with very poor connection. It hangs on this for about 30 secs before ultimately realizing that there is no network connection whatsoever.
I haven't seen this (or perhaps never noticed) on stock GB. I didn't have stock ICS long enough to know if this were the case on Motorola's OTA. I started noticing that my phone showed full 4G connection for around half a minute, when in subway tunnels/other areas with very poor connection in general, while I was using spc_hicks09's cm9 ROM, but I never actually checked the signal strength in settings. I thought that it was some bug that was present in all CM9 ROMs for Razr. Now I am running, mattlgroff's arctic ROM and I am still having the same problem I first saw in the CM9 ROM. This time around I checked the settings and saw that the 4G was registering 2147483647dBm
I haven't seen this reported by anyone else. 4G works well otherwise along with 3G and 1X (yuck!). Incidentally, a quick search shows that 2147483647 is "The largest positive value of a signed integer on a 32 bit operating system." Maybe related?
Recently I fastboot .211 and updated to .215 while keeping to stock and root - I still see this problem.
Thoughts?
confirmed
Have seen this response at home which is definitely a fringe area for 4G (maybe 2 to 5 % of the time with a marginal 4G signal balance 3G).
Happens just before 4G drops out completely. No ill effects observed.
Is it causing you issues? I am only getting 3G and 1X but whenever I'm in the bigger cities, I will get LTE for a few minutes but then 2147483647 dBm comes up in the signal strength in the testing menu and that's where the LTE goes away for good. It won't come back unless I toggle airplane mode on/off and it comes back but occasionally connects. Does the same thing on Latest Stock ROM. Started about a month and a half ago. When did it start for you?
Sorry dude I no longer have this phone

Curious issue with my Titan II. Cellular data connection just fails at random intervals. Cycling airplane mode or rebooting the phone is the only way to get it back. HTC blames it on AT&T and AT&T blames it on HTC. I've spent hours on the phone with each. Even got a new Titan II from AT&T, but it went into this constant reboot loop, so I went back to the first unit.
Now comes the interesting part: I live in Detroit and have been traveling to FL quite a bit, this year.. and the issue DOES NOT HAPPEN IN TAMPA. Phone runs perfectly well, there. Here in Detroit, cellular data "up" time ranges from 5 minutes to 14 hours when static. 2 minutes to 20 minutes when driving around town. Drops are less frequent when streaming something.
HTC Titan II stock (FW: 2180.0400.118011.502)
Windows Phone 7.5 (7.10.8112.7)
4G SIM card (3rd one)
Appropriate data plan
Serious thanks for any ideas anyone has. Do I add an APN, throw the phone against the wall, or what? Please do not suggest I change to a different phone as that is not an option.

Yes, I'm facing the same issue.
It seems something related to wifi sleeping when the phone goes stand by and the solution could be keeping it alive in some way....like streaming..
I hope this will be fixed with AT&T Tango 8773 Update (Once it finally come....)

Are you sure you aren't hitting "black spots" on your network? If you have random connection drops in only particular area it is likely the masts and AT&T issue. I've swapped my provider from the one which did 2G/3G signals to 3G only provider. 3G only has better coverage and lesser black spots on the network and hence I hardly see any drops in connectivity. Don't hard reset or anything, it will only make you re-do the whole phone, won't help the cause.
Have you checked if two golden pins on the back cover are making good contact with phone?

Have to rule all of that out as it doesn't happen at all in Tampa. I can drive from Ybor City to Clearwater and back and never need to reset the phone. Here at home, I have four bars and will lose cellular data with the phone in a static location. Driving around in Detroit is guaranteed to make it drop cellular data even with the phone lit up and active. I can have Navigator running and it'll just quit loading maps and giving directions until I cycle Airplane Mode. In Tampa, this doesn't happen.
In Tampa, I've gone the whole week without any need to reset the phone. I can't walk from the gate to baggage claim in Detroit before it loses its data connection.

UPDATE: Cellular data connection is a little better with WiFi turned off. It won't lose it as quickly in a static location, but still loses it as I move between towers. Also had to reinstall a couple of apps that had stopped launching.
Is forcing Tango an option?
I have the same problem,
I live north of detroit.
my phone has been in to htc repair 3 times, i think they have replaced every part in it, the last time i got it back it held connectivity for 11 minutes.
this is on my home tower as well as several towers around me.
Normally all testing was done with wifi off, on towers where the lumia 900 and my wifes iphone have never lost data.
i have been waiting a week for a htc level 2 rep to call me.
we shall see
Keep me posted. Last time I spent time with HTC, they decided that - since the issue only happens in Detroit - that it was AT&T's problem. AT&T, naturally, claims that the problem doesn't appear on any other device, so it must be the device.
Can't wait for Windows 8 phones. I'm getting one.. ANY one.. the first day they go on sale.
Well I just got off of the phone with a level 2 rep from HTC, who seemed pretty confident that the problem is the rear cover. He is sending one out, and says if that doesn't fix it then it will be a phone replacement.

I'm more skeptical than you, trust me, but it would explain how so many people get the same problem with replacement handsets, as that piece is often not replaced
So, I'm in Florida for the week and noticed something.
In Detroit, the status bar says "4G"
In Tampa, the status bar says "LTE"
As before, I have not lost cellular data connection since I landed in FL. Kind of rules out the battery cover as the issue is gone, here. It appears the issue goes away in LTE areas while it's present in areas yet to get LTE. Detroit's LTE rollout hasn't happened, yet. So, it appears I've got another month of suffering before the problem is rectified.
One other note. With Internet Sharing set to ON...
In Detroit, my wife's laptop connects to the phone and can get internet.
In Tampa, my wife's laptop connects to the phone, but cannot get internet. It gets the error msg: "your computer is trying to use a dns server that is incorrect or doesn't exist"
My laptop works flawlessly connecting to the phone's Internet Sharing both in Detroit and Tampa. For the life of me, I can't find anything different in her settings over mine. Both are Win7. Hers upgraded from Vista, mine x64 and new this fall. Also, two internet-capable televisions connect to the phone and get to the internet flawlessly. But something with LTE doesn't like my wife's computer. Odd.
Honestly, I adore everything about this phone except for the data connection issue in Detroit (and a few other areas, it seems).
There HAS to be a setting or SOMEthing I can tweak to get this thing to work in Detroit.
Check battery cover, radio negotiation, firmware of radio

Hum.. that's curious. I had the original titan with similar issues.
I disabled wifi when not connected. I replaced battery cover also. The titan2 supposedly fixed that issue with the battery cover because it was a design flaw.
The radio supports 2G, 3G/4G/H and LTE. You may want to check it. You can set the radio it uses and not let the firmware decide which radio to use. You can check the service menu, I forgot the code. Just search for it.
If you use 2G, data and voice are not supported simultaneously. Check and make sure the contacts on the battery cover and on the phone are clear of debris. Use a solution to clean the contacts on the phone.
In the past I manually set the radio to 3G (HSPA and HSPA+) [HTC Pure, HTC HD2 on at&t]. The 3G radio is mature and should have less issues with the radio negotiation.
BTW, there is a keep alive wifi app also.
Thanks. I'll have to look for the codes. It's pretty obvious after going back and forth so much that the Titan II has a flaw with the way it handles AT&T's 4G. Scanning the maps from others who have had problems all show that they're in areas with 4G but without LTE.
Yeah, if I could force this thing to do LTE or 3G I think we'd be fine. It's the Best Phone Ever so long as it gets LTE, 3G or Edge. Anything else and it's crap.
Yes, back connector is okay and I've done this every way one can think of and kept notes. WiFi doesn't matter. On or off, the T2 will lose cellular data connection randomly in 4G areas. NOT in LTE areas. I'm only unable to test it on other carriers.
Similar problem with data
So I have had a similar problem -
I had a Samsung Focus, great phone, but I wore out the USB port - wouldn't charge consistently or sync. I figured I might as well use the insurance I had been paying. They sent me a Titan I - it had the bad microphone issue. So after some messing around they sent me a Titan II.
It has never had consistent data connection. I am in an area where I get the 4G icon (not LTE).
My experience tells me that if I move around and change cell, or lose signal in the cell I am in for any reason, then the phone will NOT connect back to data. It can (almost always) still get phone calls and send/receive texts and so on, but no data. Toggle airplane mode always fixes the problem, until the next time.
Originally HTC wanted to send me a new back cover - AT&T have been completely useless, they have no idea. Eventually after messing around with factory resets, powering on and off continuously, another new SIM card, HTC decided they want the phone repaired or replaced (level 2).
It is still inside the 30 day limit for exchanges from Assurion (AT&Ts insurance carrier) so it's getting replaced. I'll let you know if it fixes the issue, but I haven't been in an LTE area so I can't check that.
Personally I think it is a problem with handing off/reconnecting to 4G tower service - we'll see......
Anyone have the radio codes?
I've had the same problem since I got the device as well; but have noticed that it doesn't happen in all areas around me. My house is one of those areas though that I always lose connections. I've tried every APN / idea I've found on the internet with no luck. It's clearly something to do with AT&T towers. The only think I've not been able to try is a different SIM card in the same phone since it requires a '4G' sim card to even work at all. However the same SIM does work fine in '3G' only phones.
Going with the radio idea, does anyone have the codes to turn off the LTE radio? I just saw the list saying this phone will be long gone before AT&T ever gets LTE in Colorado so maybe just turning it off would help. Every code i found was for the T1 though and it didn't work on my phone.

I'm more skeptical than you, trust me, but it would explain how so many people get the same problem with replacement handsets, as that piece is often not replaced

UPDATE: HTC insisted on sending me a new SIM card cover (since it contains the radio's antenna). Despite my argument that the fact it works in Florida negates antenna as a suspect, they sent it along, anyhow. Naturally, there is no change. It still randomly drops cellular data. And now, I've picked up another spot on the freeway where my calls get dropped. Granted, it happened ONCE, so that could be any number of things. Long story short, it's not the antenna.
Next idea?
Well, I'm in Florida and found a spot where the phone fell back to 4G from LTE. Data issue returned. So, that takes geography out of the equation. The phone can't hold a data connection when using 4G. So, should I go for a fourth unit?
My addition:
AT&T recently rolled out LTE to my area in CT. I never had the problem before on straight 4G. Now, when I go from LTE to 4G (my drive every morning) data just stops working. I push it in to airplane mode and back out again and it works.
BTW - I am running Tango, so that is not likely to be a fix unless a radio update is released with it.

AT&T just switched on LTE metro-wide, last night. Now, the Titan 2 performs just as it does when I'm in Florida. It's nice having a data connection that'll stay good all over town, again.
I have spent some time discussing this with HTC and AT&T. Actually just got off the phone with HTC level 2.
I too have gone through all the options - new phone, new cover, new SIM card (you can just go into AT&T and ask for one, no charge), hard reset, everything.
From the information in this thread, and elsewhere I can say that the phone drops data on one of two things happening:-
- connection to tower is interrupted in current cell, but is re-acquired
- connection is handed off to adjacent tower as you travel to a new cell
Both these things will drop data IN 4G AREAS ONLY. If you are lucky enough to have consistent LTE in your area, you shouldn't have any problems.
Right now I'm working on getting the service menu codes so we can play with the radio settings. It sounds like HTC support reps have been forbidden to give these to end users on windows phone devices (I wonder why??!!).
If I get this information and it provides a fix for this issue, I will (obviously) post it, and I imagine HTC will as well. Here's hoping.....
