[Q] Loss of HSPA reception - Captivate Q&A, Help & Troubleshooting

About three days ago, came home in the evening and my phone suddenly had weak to no HSPA signal, and was instead reverting back to EDGE. This has persisted constantly since about Thursday, and I'm not sure why. Reboots will occasionally bring back a no-bar H signal, but it will usually be lost and not come back after a while. I live in the downtown part of a city, and don't really expect this poor reception in my house, especially since I've had excellent reception here for months and haven't changed anything on my phone in the last couple of weeks.
I'm running S7 with JV6 modem and talon 0.4.4.21 kernel. Any suggestions on what to fiddle with? Or perhaps know of any work done on ATT towers that could cause such a signal drop?

Well, if you can step outside and get good signal, then my money is on some new interference in your building. Apartment buildings can be a nightmare of RF sources, so tracking down interference might not be easy.
Know any HAM radio enthusiasts in the area? Those guys are pros at identifying rogue radio signals.

quite possible its just ATT's ****ty network. tower nearby could have major issues

Just last week my wife's cappy showed H but she couldn't make a call or send out a text. So I checked my phone and same thing. Rebooted both phones and when they powered back up I had NO bars at all. After about 10 minutes it had bars but edge or nothing. I called att and at first they did not show any work in the area being done or gone bad. Went through their testing and still no go. Finally they sent me to tech support or something who did some digging around and took the report. After another 30 or so minutes I had some H bars come up but then lost them almost immediately. Then they started seeing more reports come in and finally I found out that a area from my city to cities about 20+ miles away all lost their signals due to something going wrong. So about 1.5 hours after I noticed it our signals finally came back.

Yeah, I'm thinking it's the nearby tower. Drove around a bit in the hurricane early this afternoon, and noticed that I had full H reception. Came back home, and was back to 4 bars of EDGE...and a clock that was exactly 4 hours and 6 minutes slow, thanks to the network. This tower (downtown Albany, NY, if anyone's nearby) is having some serious issues...

ATT HSDPA in my town!!!

So I was just out getting my midnight release copy of GTAIV on Xbox 360. I was in the middle of sending a few pictures of the event to a couple friends when all the sudden, at about 12:15am on 4/29/08, my Tilt switched from E to H!!! I couldn't believe my eyes! I thought my phone was lying to me so I ran a couple speed tests using Opera and sure enough the first test hit over 600kbps!! Usually I see around 200ish.
Just to be safe, I just got home and the first thing I did was tethered. I ran a speedtest from speedtest.net and saw 1.1mbps which is usually at around 300kbps.
Now here is the good part of the story. I have been hounding my ATT reps every chance I get asking when oh when 3G was coming to my hometown and they have been telling me July/August at BEST. So I'm thinking I may have stumbled upon ATT testing it out tonight. Still very cool. I guess tomorrow morning will tell whether or not it stays or if this was a test!!
What a great night, GTAIV and HSDPA... what more does a guy need?
Oh, I live in St. Cloud, MN.
UPDATE: 9:30AM and it's still on!

What more? Just this... here. (Link May Be NSFW depending on how Communist your Work is.)
BTW Congrats on your HSDPA. I've been loving it for a few months now.
I live in the Bay Area and I also experience HSDPA at times, mainly shortly when I'm on the freeway.
well, Italy, in this kind of stuff (pretty useless) is almost leader in the world.
we are completly covered by HDSPA, from at least 2-3 years.
but we have prohibitive tariffs (like $2.34 every 15mins or $47 for 100hours)
HSDPA has been on Minneapolis, MN from 10/2007.
its great isn't it? one day I looked down at my phone and say "3G" instead of E. I live outside of bakersfield ca. was a nice day for me.
1. no offense
2. I HATE YOU!!!!!!
3. I REALLY HATE YOU!!!!!!
4. Now let me apologize.. I'm sorry that I HATE YOU!!!!

Ahh this is fantastic. I've been waiting for this day for years. I've come to realize it's basically like the transition from dial-up to cable internet. Man, I went nuts that day!
Now I can finally stream all my music to my phone without it having to buffer every 5 seconds! Horray!
AT&T has definitely been upgrading HSDPA in the US. Many think it is being expedited for the release of the 3G iphone. AT&T did the same thing to their Edge network right before the current iphone came out.
I am in NJ also, and I've had a 3G indicator all along, and an H indicator when downloading data.
In the beginning of April that changed to a constant H indicator.
From inside my office, 4bars H, 1mb test file from DLS Reports 665kbit/sec ... although I've seen better speeds over 999kbit/sec from other locations.

wow thats odd..when i first purchased my unit which was in March, i found k.tweaks and did that change first and every since its been on H.. i rarely get 3G anymore in fact.. if i do run low on service by my job, or low zones, it either goes to E or G.. i havent seen the 3G icon in about a month now
oh and when i ran my DLS report i got the same stats u had..
I've had my TILT since Nov 2007, and I also had enabled the HSDPA via tweaks.
I would always see 3G, unless I started a download ... say a podcast via Newsbreak ... then the icon would change to H.
The constant H is definitely a network change/upgrade.
Many of us thought it was a problem ... kind of comical now looking back:

3G/HSDPA has been in the bay area for quite some time. I'm surprised you don't get it.
By the way I noticed differences in speeds in different cities. For example in San Francisco I get a 3G icon and it will switch to H when doing data. DSL speed tests are usually around 500. In New York City I never see a 3G icon, H the entire time. Speed tests are closer to 900-1000.
Half right Jstar ...
732 part is right.
Proto part is wrong.
As a note, mine is a constant H. I have not seen a 3G icon yet.
If you guys want to see some more data speed tests, please check out my other thread I created with a bunch of results.

Nexus One 3g Issue?

I have been wanting a nexus one really bad and the only thing holding me back is the 3g/edge switching problem I have heard some much about. Is this really that big of a problem? Should I wait for the HTC Desire?

How is the signal strength where you live? I have had my Nexus since the day it launched, and dont experience any of those issues. But then again....I have great 3G/HSPA connectivity here in Denver.
I live near Detroit MI and the 3g is ok. I do get edge 40% of the time when I am in my house but wifi fixes that.
I have had mine 48 hours. It has worked properly about 2 hours. The rest has been filled with lost data connections, signal going from 4 bars to zero bars, and back to 4 bars within seconds, and many many missed calls/messages/aborted calls. NOT HAPPY AT ALL. I thought this was going to be an upgrade from my G1- the speed is great but it is totally unusable as an actual phone. BTW, 3g in my area is excellent (on the G1).
I'm in Tulsa, OK and have yet to see EDGE on my 3G ATT Nexus. I've had it all day and been all over town and now home and I've got 3G all day and 4 bars 3G at home in the house.
I had my Nexus since the day it was launched, and dont have any 3G issues. I have great 3G/HSPA connectivity here in Las Vegas.
I had my N1 about couple months and so far it seems that it's the only choice!, didn't get any major problems, amazing speed I always get daily updates!

Las Vegas is one of T-mobile's best connected cities... so no surprise there. But even in Toledo, OH, I get 3G outdoors without issue and switch between 3G and Edge only indoors, where I have wifi anyway.
Maybe you guys that are having problems might call HTC for swaps.
All of this worries me. I don't want to shell out $530 for a phone that could have issues with keeping a 3G connection. Even on cyanogens wiki he sates "Is the 3G issue fixed? No. While Google did issue an Over-The-Air update On 2010-Feb-02, it doesn't fully fix the switch from 3G to EDGE, which might be a mix of a hardware problem and a software one." I am hoping the desire comes out soon to see if that has the same problems. It is almost the same hardware so I would think it would be the same but we will see.
If anything it's the baseband programming from Qualcomm... I'm NOT seeing as bad as an issue as before. I do on occasion see it go to EDGE; I've just not got in the habit of leaving my phone on 3G only now.
no trouble in austin tx 3g and H all the time
Called HTC and they had no other solution but for me to loose $45 (because it was etched) plus shipping to get me another phone that would likely do the same thing. So, I rooted and crossed my fingers that having a choice in radios would help. Nope. Oh well, it looks cool. I use it to show off, and make calls with my G1
It's always good to try another SIM card(S) from a different carrier before coming to conclusions.

That's really not possible in the US. We have 2 GSM provides and both use different frequencies. You're definitely not going to get 3G with the other provider's SIM.

Ughhh, I'm line of sight to a tower and get -70 to -75dBm all the time but I swear I jump for joy if I manage to get 600kps on this N1.
I went to the outdoor mall in my neighborhood that has the T-Mobile antenna there. I was getting about -75dbm and when I covered the back of the phone with my palm as demonstrated in the videos showcasing the 3g problem my reception would drop to about -105dbm... is it me or is that excessive considering how close I was?

Only getting -105 to -111 dBms -- PROBLEM?

I live in "moderate coverage" area(confirmed by 3 separate ATT reps). I got myself the Captivate the wife got the iphone4. In my house, the iphone gets 1 bar and in our home no bars. Obviously no way measure iphone signal in dBm's(good job apple. It is really a walled garden isn't it).
On captivate, i keep oscillating between -105 to -115dBm and from 4 asu to 1 asu. I really really love the captivate and I was looking forward to a decent Android GSM phone since I travel to Europe/Asia a lot. But the signal is really bugging me. A few times, I couldn't hear the other side properly(the iphone was much worse in such cases). I have till Thursday to decide whether I was to keep the phones or return it. I am very weary about committing another 2 years to death-star is this is going to be an issue.
Can people please advise if this is really a problem OR just ignore this and live with this. I really love android but need a GSM/World phone due to my travels.
Please put me out of my misery. I can't make up my mind
Buy an AT&T Microcell if they are offered in your area. That is probably the only thing you are going to he.able to do about the coverage situation.

i complained a lot to 3 different supervisors and they wouldn't offer a free microcell. Would give $70 credit, but did not realize that if I buy the microcell, it add $20 monthly fee. I am not sure if the last supervisor was bullsh****** me, cause the store rep didn't mention the $20 monthly fee.
I was out of contract when I upgrades, so if I return I will go back to no-contract.
i suspect it's reading falsely low or weak - i've got a vibrant and it generally reads the same, where my earlier MT3G would show -63 to -87
but mine doesn't drop calls and pulls 3G and sometimes even pulls down HSDPA
depending on traffic on the web, while showing -111 dBm, mine will test at speedtest.net showing as high as 5.4 Mbps download,
it generally shows 1.6 to 2.6 Mbps but again, all those test results were while showing -105 to -111, same as yours
the Mt3G, while it showed higher signal strength in same spot, never got above 1 Mbps download speed, which is why i'm thinking the signal strength is reading falsely low
if you're not dropping calls and pulling down at least 1 Mbps download speed, i wouldn't worry about it
but in case it helps
I bought 2 at the same time (one for me and then one for the wife). Her's was having the same issue. We have a MicroCell and I get 5 bars and like -85 dBm while her's was showing one bar and -100. Bad antenna. Return it for a functioning one.

I could be wrong, but, I was under the impression the $20 monthly fee is only if you use the microcell in conjunction with your home internet to get unlimited (doesn't go against your rollover minutes) calling from your cell number. Thats how you get the MC free, otherwise it's $150.
After trying another 2 reps, I actually found someone who actually figured that my 3g reception is really really weak and shipped me a microcell give me the credit of the full amount. Finally got lucky. Anxiously waiting for it to try out the signals. I will post my findings here. Need to buy a homeplug adapter so I can keep this by the window. I really hope those works out as I really like phone

I get four bars in most of my house which is so much better than no bars. The call quality is much better and all calls are very clear. The iphone and captivate both hold the calls much better now. I am glad this resolved my basic calls issue and i get to enjoy this excellent phone.

Does anyone have data on what good signal numbers i should see? Should I see positive DBm? If so, what? Positive 90? Or is Negative 50 OK?
I can't seem to find good reference material, but I don know when i leave my basement my signal goes from Negative 107 to Negative 95.
Thanks for any references or education.
A higher but negative signal is stronger, with -50dbm being extremely strong, -90dbm usually supporting weak data, voice being acceptable to -95dbm and anything lower than that is considered an unusable signal for most mobiles

What is the best signal strength you gotten.? I think mine is -91 it doesn't seem that good. How about you guys? Oh i am in Houston.
Sent from my Nexus One using XDA App
I've personally have seen my phone hit -50dbm which I believe is the highest this receiver will read. However this is very sporadic and rare. On average it is in the 90s which is unacceptable. Even beside my girlfriends BB my signal is always 30dbm lower than hers. Keep in mind dbm is a logarithmically scaled unit so 30dbm means my signal is roughly 10 TIMES lower than hers. 3dbm is twice the power

When do you measure your signal levels?
I got same weak signal during cell standby (no phone call, no data traffic).
However!
After initiating data transfer/call signal increases significantly. I'm getting -60-80dbm.
This means radio is saving battery juice when not extensively used, which should be considered positive.

I've noticed this too, at idle if I have one "bar" and I initiate a phone call the bars will increase to 2-3. However, there are times where I am on the fringe of no signal whatsoever to even initiate a call or to use data because the signal received is so low. Also, when my captivate reports 2-4 bars its usually still at -90dbm. I just did a test by calling someone and watching my bars, although the bars went up, while the conversation was still engaged I was only getting below -90dbm. I'm about to head to the store to check out a replacement
Just traded phones, this one seems to have the same issues... I'm curious if the build date has anything to do with this. My first Captivate was on 7/27/10, this was printed on the battery at least. The AT&T rep gave me just a new phone while using my same battery, how can I check the build date of the phone with the serial number? I've seen mention of this somewhere on these forums about a link at Samsung that will tell me
Edit: Figured it out, it's under the Samsung product registration, when you enter your IMEI it tells you the manufacturer date. This one is also 7/27/10... I wonder if it's a common problem with older phones. Can you guys having this problem verify your manufacturing date?

The 4G bug

I've heard of this and it finally hit me about two weeks ago. After about a week of being on unofficial .905 with a motofail root my 4G stopped. I tried progressive measures until finally just doing a factory reset and flashing stock .902. After that still no 4G. Then I let the phone stock update to .905, still no 4G (i mean literally never and I live right next to a strong Verizon 4G tower.
After the .905 update i tried pulling the sim and then rebooting, changing Android ID with Titanium, then reinstalling sim while subsequent reboot was ongoing. After doing this twice I got 4G with full bars for about ten minutes before going back to 3G. After that I could never get 4G again no matter what.
So last night I updated to the ICS 33 build hoping for a change. Nothing. I did a clear data and change Android ID, pulled sim a million different ways. It's just not going to happen for me. This phone has never been wet, abused, or had a custom ROM, btw.
So i called Verizon this morning and here is where my question comes in. I was honest with then on all that I've done to the phone and their basic response was: "we know the Bionic has an LTE issue and will send you another free at no cost right now." That's pretty awesome, but I'm now worrying about protecting the phone from losing LTE ability again. I really like the ICS leak and want to install it as soon as I get the new phone, but I don't want anymore LTE problems.
Are there any strong theories on why this happens? Anything to avoid? I'm leaning toward thinking it may be a hardware thing affecting a certain batch and then convoluted by the refurb tendencies of the day. Does that sound logical?
On a side note, if anyone has something they want tested let me know. I can do it to the 4G crapped phone before returning.
I had an issue with one Bionic where the 4G drivers kept disappearing, and then finally one day never came back. They replaced my phone. It happened once on my new phone when I first had it, but hasn't occurred since. I personally think the 4G radio gets burned out and shuts down, but have no way of proving it.
Insane! Just got done doing done housework and now i have LTE; the usual 4-5 bars.
I am now thoroughly confused. It hasn't worked once in over a week.
So now i get to see how the battery on 2233 holds up with LTE. Running 905 with 3G only was a treat in that one respect. I was getting 33 hours typically. That's with checking news and Facebook like 30 times a day, at least a call an hour, steady Wordfued games, Bluetooth/GPS on all the time.

4G is not a Bionic issue
Verizon can say what they want - but the 4G issue is localized.
I travel a lot - from VA to PA frequently, and out to Denver regularly. A couple months ago 4G just went away (note that Richmond and Denver both have extensive 4G coverage).
I can get 4G in Newport News, VA, but not in Richmond, Denver, or anwhere between Richmond and PA (like DC or any of Eastern MD, or Delware). These are all places where I used to get 4G consistently.
I've tried multiple reboots. Nope - only place I now get 4G is Newport News. I also have firends/coworkers on Verizon (my company uses it), and NO ONE can get 4G in Richmond any more, on any phone.
My 4G cut out this morning in a certain area...I typically get 4G in that area and it is on an extended 4G coverage area. I noticed my phone lost 4G rather than switch over to 3G. I saw it go from blank to 1X to 3G and never recovered to 4G. I am currently in a 3G area atm and won't know if something's changed til i go home where I will pass thru the extended 4g then 4g.
In Boston I frequent a few areas and for over 2 WEEKS 4G would not function near one of my haunts. It used to be 4 bars and had decent speeds, then all of a sudden whenever I was in the area my phone would keep switching from 4G to 3G, but if I walked a couple blocks down the street I had a full 4G signal again and data worked perfectly. After the first week the problem became even worse, the phone would get stuck with a white 4G symbol and would keep toggling from white to blue but never got a connection and thus the only way I could use data in the area was to use wireless. Again if I walked a couple blocks down the street I had a full 4G signal and perfect data. Then one day the problem just went away.
I've heard similar stories from others around the country so it appears Verizon is having serious localized issues with some of the LTE towers. This happened in late June through the first week of July and I haven't experienced the problem since.
I should note I also did have the issue where 4G stopped working completely when I installed one of the leaked GB builds and the solution in that case was pulling the SIM card, rebooting, then replacing the SIM card and all worked again after about 10 minutes.
currently in middle of Fresno, CA and no 4g...
I had major 4G issues with my Thunderbolt.... I just bought a Bionic and now I am having the same issues.

I rebooted my phone in a 4G area this morning. The 4G icon popped up briefly and then quickly disappeared to the 3G icon. I never had 4G problems before and now this is happening. I am annoyed but not to the point where I need to switch phones.

Question about reception

I recently (last week) got the HTC One coming from the HTC LTE and notice that it seems like every few minutes I lose network connectivity. More specifically when listening to streaming music. Even if the phone is stationary and doesn't matter what part of town (Kansas City), that I have where the music stops and buffers. Also had dropped a call on a road that I never had issues with phone calls before.
The phone was rooted, and took it to the Sprint store and they told me that the towers in town were all flaky (bad thing to say about their network), and that they didn't have a method of testing the radio. That night that I took it to the Sprint store, the girlfriend tried to call me and didn't receive the call and she sent me 3 texts that actually showed up while the CSR was holding the phone, showing that it was delayed by 2 hours. They did a profile update (think honestly they just wanted me out the door).
So I used the RUU to flash back to 100% stock once I got home to ensure it wasn't something that I did rooting the phone. Having done that, over the last few days still having the network buffering issues (didn't have that with my old phone), and haven't had any delayed texts (that I know of).
Question is do you believe them at the store that it is a wide are Sprint tower issue, or that it could be my phone? Don't want to wait too long, and end up with a refurbished one either (someone else's problem phone). Is anyone else having the same type of issues that might be able to be fixed with a software flash????
Thanks in advance!
I know lately I've been having dropped calls a lot. Two tonight actually with decent signal. Idk if it's my replacement phone or a rom I flashed.
Sort of tough to figure out which it could be.

Tried my girlfriends phone using Tune-In listening to the same channel and her phone does the same thing. She also have the HTC One. Just wonder if power management is just too tight and not enough processor to keep the stream going. Full bars in a 4G area and still buffers. Even when sitting still in my house!
Just very frustrating!
Mine was doing it too. Dial ##72786# and reset network settings. The phone will reboot and go through the hands free activation... After that I have not had any issues... FYI, I'm actually a tech at a corporate sprint store, and I'm surprised by how many reps don't know that ##code. The network being flaky is a real thing because of network vision upgrades taking large sections of our footprint offline for upgrades, although I can understand that it hardly instills confidence in our customers... However it is not a catch all for what could be a hardware issue.

You will not lose any data, doing reset for hands free activation.

I've had similar issues in Overland Park and Lenexa lately. I did the reset mentioned above and it helped somewhat. About the same time my wife began having issues with her iPhone 5 so I think there is a network component as well.

Well, still having the issue after driving to Wisconsin. Dropped streaming music, and while using GPS app, get lost and now in coverage area messages. Made the trip many times before and honestly NEVER have had an area where I lost service.
Decided to not take no for an answer and took my phone to the local corporate Sprint store and the lady said well, nothing we can do about it. I said nothing? She said that they don't have LTE here and now way of truly testing the phone. I asked there was no other test that they could run?
She responded that they could run some really basic tests but it probably wouldn't show up (i.e. she wanted me to go away and not waste their time testing the phone). But stuck to my guns and left it with them for an hour.
When I returned, she made sure that she was the one that there to tell me the results, which according to her that the phone "once" failed a particular test, kind of hinting that it passed it other times.
She said that the phone should be in today, coming via UPS. I told her that that if it wasn't in today that I wouldn't' be in the area due to leaving for another part of the state then heading back to the KC area (this was last Monday) and they didn't have the HTC One in stock which she said no, they didn't carry it.
Then as I was leaving she asked if I was get a survey call, if I would rate my visit with them as a 4...
Going to throw a fit if they give me a refurbished phone since I have had the phone less than a month and had problems from day one.
Data Loss During 3G/4G Change
I experience the same thing in the Minneapolis St. Paul area. I drive a lot for work and as I'm driving and the phone switches between towers I loose data connectivity completely for 30-40-60 seconds, sometimes more. I can sit there and watch the 3G/4G indicator go from lit up to dark during the switchover. It's really frustrating if you're using a data app like music streaming. I initially thought it was only happening when switching between 3G and 4G towers, but lately I've noticed it also happens between 3G towers, although 3G/4G is definitely worse.
I hope this is not a phone issue and is only a temporary tower upgrade issue.
Do you have EVDO enabled?
*#*#4636*# I think. Then change the data preferences.

I work in Minnetonka and experience the same issues while stationary! I'll be sitting and poof signal lost, haven't moved an inch.
Unfortunately I've only picked up 4G while driving, but I will try repeating your results on my next drive to work.
In general it seems like this phone doesn't receive the best signal.

Interesting. We have a 4G tower near us in Shorewood. I think the tower is around Hwy 5 and Powers Blvd in Chanhassen. Once I lock into the 4G tower I'm fine - it doesn't drop data, but it always drops it when switching between 3G and 4G. Last night I was driving to Jordan for a meeting and watched it all the way down. Not bad switching from 3G to 3G towers, but as soon as I hit the 4G tower signal in Jordan I lost signal. After watching it closer I noticed that the data indicator sometimes goes away completely on the phone, and when that happens it's like a minute or two before it restarts.
I'm going to put in a request for technical assistance from Sprint and see what they have to say about it. Maybe this is just the way the system and phone works since 3G and 4G are so different, but I sure hope not. It's annoying.
