reception sucks!

I hate to say it but I am having 3g issues. By that I mean no 3g and one to two bars. Usually I have perfect reception.

i've noticed on the incredible that my displayed signal strength isn't as strong as it is on my droid. haven't noticed a difference in call reception or data speeds though...yet.

Eris users have noticed the same thing as you bzbz when compared to the Droid. Could be the cpu or something else HTC vs Motorola.

I noticed the same thing but my download/upload speeds are just as fast if not faster. I gave my Droid to my mom and took her upgrade so I have both side by side, off WiFi downloading a movie and the Incredible is actually 20-50kbs faster than my old Droid and yes the Droid is over clocked with petes 1ghz kernel.

I have had the Incredible for a couple of days, and I've noticed a lower displayed signal strength than I'd see on my Droid in the same locations.
But I've not experienced any reception issues, and my internet speed seems the same or faster.
This is what I expected. We all know that you can't count on those reception bars to compare different phones, and also that Moto tends to have better radios/reception than everyone else anyway. As long as you're phone's radio is close to Moto's in the ability to make/receive calls, then normally you're not doing bad.

well it's good to know that the signal strength concern may be more of a "cosmetic" issue than a legitimate performance issue.

how is the quality on said reception? Other people's replies seem to indicate good quality even with less bars.

It is definitely cosmetic, the newest radio i have installed on my eris does the same. The reception on my eris is better then my friends with the older radio, but he has more 3G bars.

It may just be the way HTC displays the signal. I know on the Touch Pro 2 and Touch Pro, the signal indicator frequently shows incorrect (lower) signal strength but works fine.

I compared signal strength between my BB Curve 8330 and my new Incredible.
In spite of the indicated signal strength being lower on the Incredible, the dBm was the same. It's only one location and one user, but I suspect it's not an actual signal strength issue.

i used my incredible all day. i work in a downtown area with many tall building surrounded and i still got a good 3g signal and speed.
from Boston.

the 3G speeds on my incredible are slower that my 2G G1 running on AT&T. i get les than 200 kbps downstream. My friend with a droid standing in the same room will get aound 1100 Kbps. What gives??

if you are haveing a tough time with a signal.. I update my roaming towers... I had an issue today where I couldn't get much.. I did *228 option 2 and it updated my roaming towers and have had no problems since... sometimes you need to do that with a new phone so it knows exactly what towers to look for

tried the *228 to update. Update was successful but no improvment. still have very slow data speeds and terrible call quality. reception stays about around -100 dBm

I'm also noticing what appears to be poor reception. I was getting better reception with my Droid than I am with Incredible. I've tried the *228 last night and this morning but that hasn't helped. Hopefully there will eventually be some kind of software fix for this. I'm seeing other threads on other sites with the same kind of complaints so I don't think it's a select few who are experiencing this issue.

Your speed will depend on what tower your connected to. on my Eris, I've gone from 1mbps/0.70mbps in New York, NY to 2mbps/2mbps in West Haven, CT. It's not the phone. The newer radio on the Incredible will show less bars, but your signal strength will be fine .(dBm)

My phone keeps dropping 3G my droid never has done this in the location the incredible is. I will go into airplane mode then back out and I will have 3g again

Over at Androidforums there is a thread going regarding reception issues. On page 2 is some help in running a debug on the phone that will give you dbm levels and some other info. I'm not sure how to use the info the debug gives but perhaps it may be of some use to someone here.

You don't need to go into field test mode like this guy said, all you need to do is from the home screen > menu > setting > about phone > network.
Here you will see signal strength (typical between -100 to -80dBm) the closer to 0 you are the better your signal is (ie: 80dBm > 90dBm)
Hope that clears up some confusion. I've tested both the motodroid and the incredible side by side in a location with low signal and can say that my incredible gets better signal than the droid, even though the "bars" don't indicate as such.

my signal always stays at -81, is that a good thing?

Possible bug in Fascinate's signal strength, affect Epic 4G?

Posted this in the Fascinate forum, but I'd like to know if it is affecting your devices as well:
I believe there is a bug in the signal strength indication on the Fascinate, the one that shows the signal strength in -dBm.
You can see the signal strength of the cell signal on the Menu, Settings, About, Status screen. Or you can place a widget on your Home screen. There are several widgets available, I'm using Mobile Signal Widget.
I have a network extender, which basically creates a cell tower right in your home. With my Motorola Droid, I used to get signal strengths down to about -50 something and 60's in indicated signal strength. I can hold both of our Fascinates right next to the network extender's antenna and they will read no better than -86 dBm. So far I've seen signal strengths from -86 dBm to -106 dBm (terrible).
I believe there is a bug in the software (Baseband) on the Fascinate. Previously, I thought the hardware (antenna/radio) wasn't very good, but now it may be software related.
Has anyone seen a signal strength stronger than -86 dBm on the Fascinate/Epic?

I remember seeing it at -68 dBm on my Epic yesterday.

Hmm, thanks for that. Was that on 3G?

I also feel that this is impacting battery life. My signal is always reading worse than the Evo and TP2 (in the same location) but calls are not dropped.
This leads me to believe that the signal is actually better than the phone thinks. but since the phone thinks the signal is weaker than it is, it boosts the radio power (thus eating more battery.)
If this is not the case, the flip side is much worse and the Epic's antenna is a poor design, requiring higher power.

Every phone that Samsung comes out with that runs Android and the QSC6085 modem processor always has the same general problems.
The Fascinate, Epic 4G, Moment, Intercept, and Acclaim all generally have poor battery life, signal, GPS, and network performance issues, and other related bugs.
I know of other phones like the Droid/X/2 that have the same Qualcomm modem and have no issues whatsoever with network and GPS connectivity.
Is there any way to get source for the Droid phones and fix what's wrong on the Epic?

Thanks for all the replies. Verizon CS wasn't any help, at least the one Guy that responded to my email that I sent them.
LOL. He told me I have to contact the developer of the signal strength app I had on my phone for the problem I was reporting. WTF?
I responded by asking him to send it to higher level technical support personnel.
We'll see how that goes.
In the meantime, I'll probably exchange my Fascinate for a Droid X to get a phone with better reception, GPS function, and network performance.

Signal Strength Booster?

I get poor reception on my Incredible whereas my parents get great reception on their phone. A little googling and this popped up:
http://www.onlyincredible.com/incredible-booster.html
is this legit at all? i'm not a technical guy so I have no idea.

I call bull****. They used to sell these things for regular cellphones. They didn't work then, either.

I was thinking the same thing but trying to be hopeful ya know? I really need some signal boost. I average around -90 dBm

If you're desperate, it's not like $2 is a huge sacrifice for a likely useless piece of plastic. I don't know I usually get between 80-100dBm at my house and i have no complaints about the service... The bars don't necessarily tell the whole story. 85dBm is 5 bars on my 6bar signal meter, so keep in mind that bars don't necessarily tell how mcuh signal you have. With the stock 4 bar meter, I would never have 4 bars at my house; usually 1 or 2; sometimes 3.

I go by the dBm and just sitting my room I can go from -85 up to -120
I always thought that it would be normal for my dBm to be in the -60 range. Am I wrong or is -80 to -90 okay?

I get -91 to -106 in my room and I have good enough signal to do anything I want. Also my friend bought one of those for his Eris and thinks it actually hurt his reception but I can't imagine there's a difference with or without it

If you want something to boost your signal this is one of the only things I've found that will actually do it..... http://www.tigerdirect.com/applicat...CODE=GOOGLEBASE&cm_mmc_o=VRqCjC7BBTkwCjCECjCE
They are normally priced at $120 but can be had for $15. I bought one and currently use it in both my vehicle and home. It will boost the signal for me from around -105 dbm in my house to around -90 dbm, but I've seen it get as good as -81 dbm. I plan on buying another that way I don't have to keep moving it around.
They say it works within a 6 ft radius of the plug but I've found that you need to be a little closer than that to it.

-80dbm is the best signal possible. Also, cdma signal fluctuates. Don't expect it to stay at a consistent number. Unless you're having issues with dropped calls or slow data, I wouldn't spend another second concerning yourself over it.

Thanks for this... now would two of these work better then one?

I know people here don't take bars for much, but why is -80 only 2/5 bars if it is all i can expect? I've only had a couple dropped calls so you are probably right that i shouldn't worry about it.

I've never seen mine better than -78 unless it was some weird fluctuation for a second

0 would actually be the best possible. But it can never happen, so, meh.
As far as highest signal strength possible, I've been in the -30's before. That's the highest I've ever seen.

Same, -32 was my best

Your head absorbs wireless signals.
So, use the speakerphone more often, or better yet, use a good quality Bluetooth ear piece so the phone can sit near a window still.

keep in mind that CDMA phones with VZW use two radio frequencies. one is voice, the other is data. so the "bars" and 3G doesn't do much to specify which of those two network connections its representing. my guess is that it's representing data strength, not voice.
-80dbm is the "best" signal strength i've ever seen a verizon wireless cell phone have. and that's based on other phones, such as blackberries, winmo, etc...i'm not sure if it gets any lower than that on CDMA networks. i know my WI-FI, when at the strongest, is usually -40 or -60 dbm.
for example, sitting at home my signal is -84 dBm, and that is pretty much full strength
also, the value we are discussing is how "loud" the signal is. take into consideration that network traffic will also impact service in varying ways.

Driod 2 evdo signal question.

I have downloaded both Real Signal and Signal Status from the market. I keep having issues with my data not working(it's been ongoing since I got the phone.), so I wanted to know what my actual dBms were. But for some reason, on both apps, the highest evdo reading I get is about -3 and the lowest is about -30. But I don't know what that means in terms of real signal as everything I can find on google and that I understand, it should be between -60ish and -115ish but I have never seen those numbers on the evdo side. Am I wrong? I understand that it is the same dBm as 1rxtt, and I know they are different tech, but I would think it would be similar any way. However, I don't know antenna tech at all. So that's why I posted the question here. I have done a google search with no real relevant results, but I didn't search XDA specifically, as I thought if there were any relevant results they would have popped up in my google search. And all the relevant postings that I came up with said the same as my assumption. That signal should be between -60ish and -120ish.
Thanks again for all the help, you guys are awesome.

1 bar ~ -102 to -120 dBM
2 Bars ~ -93 to -101 dBM

I was able to hunt down that chart (Granted it was for a BB, however I would imagine the info would still roughly apply to any device), but I was not able to locate any real description of bars vs dBM. However, from what I've read before, just because you have a lower dBM (IE: -40) doesn't really mean you're going to have full bars/better service. I could be wrong, but from most of what I've read over time showed it was only a very vague correlation.

Do you get intermittent loss of data where only the right arrow under the 3G icon is active? That happens to me frequently as well and I have to go in and out of airplane mode to reconnect. Some of us think Blur causes it.

Granted, I only kept the stock rom for about 3 days before I installed a custom, blur-less rom. However, I seem to recall having some data issues while using the stock rom. I donno if it was part of blur or something else causing it. However ever since I've flashed to a new rom I havent had a single issue.

I've been having issues with data like this, too. I have put an Airplane toggle widget on my home screen just for this. I am near Fort Collins, CO, but I guess it looks like people may have narrowed it down to ROM issues and not location or Verizon.
Maybe they'll fix it when they roll us out to Gingerbread.

I have wondered myself if it wasn't blur issues. It freezes all the time, and fiancees Ally doesn't have the freezing problem and general laggyness. And I know hers only has a slow 600 Mhz processor and is just a budget smartphone.

Then should it be possible for me to hit single digits? I don't recall ever having a lower signal than -30 and it stays typically in the -8 to -20 range. When I was at about -100 cell service, I was at about -8 to-10 evdo. So something still must not be right with my phone. right now I am at -76 cell and -2 to -4 Ev.

I am seeing the same thing on my phone. I have ~87dBM cell service, and ~7dBM for evdo. I have always understood Verizon's voice and data network to be separate, I suppose this just goes to confirm that.

Here's a way to confirm if it's a problem with Blur, as opposed to VZW's network. Is there anyone who had this problem on the D2 with the stock ROM and then had the problem completely disappear (or at least reduce in frequency) after switching to Liberty ROM, or one of the others?

All my issues dried up when I flashed a custom rom.

I work in the industry. A -80 is generally the number you want to shoot for as far as having a good usable signal. Anything higher would be even better. Although once you get past -50 or so the signal is kind of hot and may cause issues. Anything lower is a bad signal (-90/-100) and would also cause issues.

I had 3g issues with the droid 1 and cyanogen but Never with blur or liberty/droid 2 from the same house. I have noticed some "cell standby" signal loss on liberty but never really bad like some cyanogen builds..don't overclock and see if that helps.

signal strength gives no indication of 4g speed?

Experimenting with modems to try and find a better one and came across something very irritating. It seems after my testing that the number of bars of signal and the signal strength reported in Network Signal Info seem to have no relation what so ever to the 4g data speed you may get.
Earlier I was testing with 4 out of 6 bars of signal, NSI showing 94dbm and something like 60% signal.....and I consistently got speed tests of around 1mbps or less and even that was slow and stuttery. On other occasions with only a 40% signal at 106dbm in NSI I was able to get 22mbps in speed tests. All these tests were done using the same speedtest server as well as subjective testing by running various apps and seeing how quick or slow they were (and the performance of all the apps matched the performance of the download tests). So what the hell is going on? It looks like signal strength has nothing to do with the 4g connection speeds.
Is the signal strength even indicating the strength of the 4g signal or is it merely indicating the strength of the phone signal because that's what it kinda looks like.
I am on EE UK with their 'double speed' 4g (which gives me 97.5mbps download when at home with a perfect signal).

Yes, in fact the signal strength and data speed are different things and they do (most likely) not affect to each other.
By detailed, signal strength is depend on if you are far or near from the mobile tower.
While data speed depend on many other factors: max capability of the network, your subscription with the service provider, and the congestion on the network.
The signal strength will also impact on data speed, but only when you are very far from the tower, when the signal strength is very weak. That may impact the data speed.

Exactly what I was afraid of. This would mean it is not even possible to test how good your signal is (for data) without running endless speed tests (which are going to kill your data usage in no time). There is no other way to test data strength?

The term "data strength" has no meaning. If you want to test for signal strength, it is the received level. If you want to test for data speed, there is no way without actually testing it.
