Better signal strength ? - 8125, K-JAM, P4300, MDA Vario General

Is there anyway to improve the signal strength on the mini S ? It doesnt seem to be giving me anywhere near as strong a signal on O2 as I got with my Nokia 3650.
Im sure I remember reading something on a model of phone where you could improve the reception although it hit the battery a little.

your thinking of the nokia's and other phones where you could enter a keypress and it would increase the signal and reduce battery life or you could decrease signal and increase battery life. but with my jam in Texas i do have a really bad reception issue, but thats because i have the international jam thats 900/1800/1900 and cingular runs on 850/1900 so thats why i'm getting the k-jam which is quad band... maybe if you go to the power settings and click move the slider to best performance, see if that helps

How do you realize signal strength is lower? Have you actually noticed lower speech quality or is it only the lower count of antenna bars on your display?
Keep in mind that there is no standard on how signal strength has to be displayed. Nokia phones tend to show more bars, whereas a Siemens phone receiving the same signal strength (in dB) would show fewer bars. They do that intentionally, so customers think a Nokia has better radio quality.

My wife said I was going louder and quieter on one occasion although I could hear her fine. In some places its only on 1 bar on the signal strength indicator. I believe there are 3 or 4 in total arnt there ? So I would consider it a weak signal.

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.

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.

[BUG] Signal Strenght Indicator

so here i got 3 Android phones
all sitting on the same spot
2 of them (SGS / XT720) shows 3 or 4 bars signal strength, but SNS only shows 1 bar, 2 at best.
however a quick test using 3G speedtest confirms the same download/upload speed as the 2 other phones.
and there's no problem calling even when it only shows 1 bar.
Can any body confirm this?
Go to settings > about phone > status and post the signal strength of each of them (should be in dBa). If they're the same, then ya either the SGS phones are overinflating their strength or the Nexus is reporting lower than it should.

im at -75 and full bars 3G
anyways... that's what i'm saying the actual usage is good, and 3G speed is good
but the bar indicator is always like in 1 bar or 2 bar... which is kinda wrong

-97db with three bars displayed here.
Sent from my Nexus S using XDA App
The farther it is from 0 in the negative, the worse the strength is. The best strength I've ever seen on an android phone was -69. Worst is in the -100's so it looks like the Nexus is actually getting worse signal, not just reporting worse...maybe an antenna problem =(

quite the opposite, 0 is just a reference point, the farther from zero the better
Mine is -101 with 2 bars.
I'm not sure where you're getting this from, but you're saying -100dbm is better signal reception than -70dbm? If that's the case then the signal strength reporting is completely reversed... as I have full bars in my apartment and it shows -72dbm, and at work I have 1 to 0 bars and it says -101dbm. It's been like this for all of my phones.
Also speed tests at home give me 500k/s down and 50k/s up while at work I only get 60k/s down and 20k/s up...

It seems like the SNS is getting far worse ACTUAL reception than the other two phone.
-107 is very bad comparing to -97 and -84.
Are all 3 phones on the same carrier?

That's interesting as there is a huge difference between the SNS and the XT720.
-84dbm means very good reception and -107 is at the end of the workable spectrum (at -113 you basically can not place calls).
I am also noticing very bad reception on my SNS but i thought that it is due to T-Mobile's crappy network. i have no other T-mobile device to compare it with though so i start to wonder if its the Nexus S that has crappy reception or T-mobile.
Try to do more tests in other locations with the XT720 and the SNS and see if you always see such a huge difference when both devices are in exactly the same spot.
I am interested in your findings.
And as for your initial question, there is no bug in the signal indicator as -107db is very bad signal so the indicator is correct.
Okay please allow me to clear up some misunderstanding in this thread...
First of all, dBm is a logarithmic measure of signal strength with respect to 1mW. So, a smaller (i.e. more negative) reading means that you have lower signal strength.
Just to give an example: -50dBm is a much better signal than -100dBm.
Alright, so now let's move on to the next issue: You can't compare signal strength on two phones which are running on different networks. Why? It's possible that you have a strong signal from Fido and a weak signal from Wind, or vice-versa. If you want to compare the RF capabilities of two phones, you should make sure that they are connected to the same network and even the same cell (you can check the service menu to make sure that they are on the same cell).
And finally: The Settings>About Phone>Status is usually not a very accurate measure of signal strength, since they are rounded off to some pre-determined list of values (So for example, if it is jumping between -100 and -110, it might actually be jumping between -104 and -105). You should instead go to the phone's service menu (i.e. you type in some code into the keypad) where you will get an exact measurement.
My friend happened to have the XT720 while I have SNS, and we happened to be at a same location where my SNS can't maintain the connection (only able to connect at one room spot with 0 bars and unable to hear a thing due to choppy voice when I tried to check voicemail) and XT720 still got 2~3 bars anywhere in the room and able to make phone calls. We are both from same carrier. We left our phone on table side by side without touching it. So despite the bars on phone nor the signal number in setting menu, real life experience tells me XT720 does have better reception than SNS sadly D: I was embarassed that night when other friends laughted at my supposely better phone

G2 signal attenuation - any better?

I briefly had a G2 and quickly returned it to T-Mo and stayed with Verizon due to the signal attenuation issues I had. Additionally, I saw numerous posts about this on AF, XDA, T-Mo Forums and a few other places I cannot remember. My question is, have the software updates that have been pushed through helped this problem any? I really liked this phone, aside from the signal problems and now with it being free through the 20th at T-Mo, I would like to give it another shot, but not if I am going to have more problems.
For those who are wondering what I am talking about, the G2 issues I (and many others) had were similar to the problems iPhone 4 users had where the signal dropped down to very low or nothing by simply holding the phone. I could sit at my desk and watch it go from an H with full bars, then drop to E, to no service, then it would gradually return when I placed it back on my desk.
Additionally, the reason I made a post about this is that the forum topics about this seem to just have stopped, nobody really seems to be screaming "it's fixed!!!" So just trying to get some input as to whether it really is fixed.
Thanks for your input!
ive noticed this as well. It usually happens when I surf the web. No idea? It is annoying but it won't cause me to send it back. I love it too much compared to all the others i've gone through. I'm sure they will isolate the problem and it will get better. (here's hoping)
Never had any places on the phone that I touch where signal will just drop, though out here in the middle of practically nowhere my signal will randomly drop sometimes regardless of what I'm doing with the phone.
I think I suffer from this as well. It constantly drops my data, especially at my house. If I set it on my desk with mobile hotspot it works great, and I'm not touching it so I may have issues with that
I've yet to have this happen. Constant h in my status bar and signal is strong.
Probably a defect phone?
Sent from my Pear phone.
It happens. It happens with every phone, including the G2. It just depends on where the antenna is and how it's held. You can play around with attenuation by enabling dBm signal strength in CM.
To enable it, go to Settings > CyanogenMod Settings > User interface > Status bar > Check Show dBm.
dBm is measured in negative numbers. A higher (less negative) number indicates higher signal strength.
-80dBm is stronger than -100dBm for example.
This is actually a non-issue.
Explanation:
The phone actually picks up signal BETTER than other phones... especially when the signal is weak. The effect that you are seeing is actually the reception returning to a *normal* level when you happen to be holding it in some particular way.
I have two phones; an HTC DREAM and an HTC VISION. Sitting on my desk at work, the DREAM will show 0-1 bars, but connected, the VISION will show 2-3 bars. Holding both in my hand, the DREAM will continue to show 0-1 bars, the VISION will drop to 0-1 bars and both will read the same dBm. Same signal when held, the VISION is just more sensitive (i.e. sensitive in terms of able to hang on to a weaker signal, not sensitive in terms of flakiness).
In contrast to apple junk, the apple junk actually has the antenna wrapped around the outside of the phone. When you hold it in your hand and the signal drops, it isn't suffering from attenuation, its being GROUNDED OUT.

Whatever the cause is, the phone was unusable when I held it in my hand normally. The only semi-fix was to hold the phone at the top near the earpiece, which was uncomfortable...or never touch it.

Seems like you just have a poor signal or faulty phone to begin with. I don't have that issue at all. In fact this phone seems to hold a data connection in weak areas better than my previous android phone did. If yours was that bad then there was something horribly wrong that warrants replacement.
You may also try CM7, it seems to keep a signal even better than my current ROM does. Not sure why, maybe it's just a placebo effect.
Humm, no issues with Wifi, H or G3 dropping, Bell network though, BUT when I switch from H/ G3 to wifi, if I am on bluetooth, it gets all garbled and I have to hangup call. I would think a location issue or some form of interference you guys are having.

Nah, I'm positive that the sentiment is that the radio hardware does suck and there are definite attenuation challenges. I've now verified this through a myriad of different Desire Z's here.
At my work desk I get HSPA and HSPA+ speeds at times. However holding it drops it down so there are 0 bars and it stays on HSPA, drops to 3G with no bars, back up to HSPA, etc... lots of unnecessary band switching whereas other handsets will not do this. They'll get a lower signal/dB all together though. And their attenuation is a lot less.
If you hold the phone upright the reception is much better. Drop it down and hold it in landscape mode and there is an immediate drop and sometimes it begins switching bands depending on the service area you're in. It can be quite annoying being right on the cusp because that's a huge battery killer.
I really wish there was at least some modest software fixes to accommodate for this flaw. I know that much can't be done hardware wise at this point but I think some improvements should be attainable through updates and optimizations. Hears to hoping because I love my Desire Z!!

I agree. I experience this the most when I browse the web since I usually browse with the keyboard open.
There is a SIGNIFICANT amount of drop in Wi-Fi signal strenght whem the keyboard is open and your hand is covering the left side (top for portrait). However when the keyboard is closed and you cover the TOP again the signal drop is maybe by 1 bar....
As far as 3G/4G to EDGR drops are concerned.... that can be taken care of... if you go into radio diagnostics (*#*4636#*#* > Phone information) and selecting WCDMA ONLY...... this will prevent phone going into EDGE if minor fluctuations occur in the cell signal. Mind you, this option is only useful if you are in a GOOD 3G/HSPA+ coverage area....

Just remember to change it back to allowing Edge if you are going to travel outside the 3G/HSPA area.
I have noticed this since day one. It was very obvious at weak signal locations such as were I work. Inside a steel building with 20 machines running on 480 volts. I have enabled 180 degree rotation in CM settings and have used it this way so much that I have no doubt that the signal is reduced when the phone is held the "normal" way, in either hand. If I hold it upside down, trackpade at top, then it is fine.... also if the H signal is strong, more than 2 bars.. then it doesn't matter how you hold it.
I have compared this to my G1, that I still own. And the problem is that the G2 seems to have trouble switching from weak H to weak E and I can replicate a loss of signal everytime. I mean that an"x" Is displayed over the signal strength meter. And I can not make calls. This never happened on the G1. I have even disabled the ability to use H and it solved the problem. So then I took the htclib_ril.so from the G1 and used it in the G2. This didn't seem to change much.... So I believe that it IS a problem with the radio, or a problem in the librilswitch.so that does not get referenced in the G1 build.prop. But is in the G2...
If anyone knows how to make adjustments to when the phone switches from H to 3G to G to E I would really like to know. I think it could be the solution we need....

When I check my phone it always say HSPA and never HSPA+ whats up when will I know if I'm on 4G I'm in a 4G market Philly!!
I received my G2 yesterday, and it is a lot better at handling a signal when you hold it in your hand. There's still a slight drop in reception when you hold the phone, but more of what you should expect to happen rather than a complete drop down to the dreaded X. Still testing it out a for a few days before deciding to drop Verizon, but I sure do like that I can talk and use data at the same time on the G2.
I've had this problem with my new G2. With either the stock ROM or CM 6.1.1 when I hold it the signal drops. This is a non-issue in areas where there's good coverage, but at my house where the signal is quite weak this usually means the difference between signal and no signal. If I don't hold it the signal improves. My Cliq gets better signal here than my G2 does. Also, the Cliq doesn't suffer any noticeable signal issues when I'm holding it.
It's funny, as I go about my daily routine with my G2 instead of my Cliq, I notice these things. I get much weaker signal in certain areas with my G2 where I got acceptable signal with my Cliq.

When I check my phone it always say HSPA and never HSPA+ whats up when will I know if I'm on 4G I'm in a 4G market Philly!!

I don't believe there's an HSPA+ icon. Just H.
Try using the Speedtest.net app to check your speeds. There's no HSPA+ on my network but I still get decent speeds. I just wish coverage was better so I wouldn't switch bands and lose signal all the time. The radio hardware on the G2/DZ sucks!

The only option I have found yet,(limited time to tinker) is to turn on 180 degree rotation and hold the phone "upside down" it seems to work every time.... So when I am in a place that has weak signal and I need to use data, I flip it around, and it works fine.... I know this is lame considering I paid so much for the phone but.... it does work.

Dissapointed in phone signal

Having just upgraded from the Xperia T to the Xperia Z2 there is only one thing that annoys me a lot. Comparing to the Xperia T, my Z2 has a much weaker phone reception signal. I work in another town and between home and work I always had a good phone signal with the T.
Now, on this same stretch of A-road, I have no signal whatsoever with the Z2. Same network provider, same sim card, same phone contract. Nothing has changed other than the phone itself. Phone network is O2
Phone Build: 17.1.1.A.0.402
Baseband: 8974-AAAAANPZQ-00005-08
Any comments?
I think cause its waterproof.
Agreed. Just switched from Z2 to G3 and G3 has much better signal..
On my Z2 at home constant dropped signal, no LTE
On my G3 hasnt dropped yet and LTE all the time.
Nexus 5 was a little better than Z2 but not as good as G3

Weak on its own does not tell us too much.
Need to examine what the phone itself receives in dbM for signal strength and it will tell you just that if you look in
Settings-> about device->Status
what does signal strength show in each of the devices you mentioned ?

Mine is weak too.
It says -75dBm 19 asu
What does that mean?

Sitting at my desk at work getting signal info as requested. Got info from Z2 then shut it down, removed sim and placed it in the T, powered up and looked up the signal info. Both phones alternated between HSPA and GPRS
**Xperia Z2**
Signal Strength: -111 dBm 1 asu
Mobile network type: HSPA
Signal Strength: -107 dBm 2 asu
Mobile network type: GPRS
**Xperia T**
Signal Strength: -113 dBm 8 asu
Mobile network type: HSPA
Signal Strength: -95 dBm 9 asu
Mobile network type: GPRS
With a direct comparison between the two phones when moving about, the Z2 has the weaker signal reception....

According to what you have said, HSPA reception is stronger on the Z2. - On GPRS the T appears stronger.

How many bars do you see ?
for reference, the smaller the number (when its negative numbers) the better the signal.
-60 is good, -112 is call drop territory. you're doing ok so why do you think its weak ?
That might be true and I cannot argue that, but the point remains that I have no phone reception/signal with the Z2 for most of the way when driving to and from work on the A33. With the Xperia T I have signal all the way.

yes but Z2 isn't all that much better than T. 3g is weak for both phones.
The larger difference is with 2G, less call drops on the T than Z2.

Do you use a hands free to take calls in the car.
i don't know how practical this suggestion is going to be, but if you can identify where the antenna is situated on both phones (user manual?) then you try to orient the z2 in a manner that does not block the antenna. Can make a difference when cell signal is weak. The way you do this is try and position the phone in different orientations and see if you get signal strength to increase (that means a lower figure in dbm)
eg, with a tab i use, i found orienting the tab in a different orientation means less obstruction and a better signal with wifi.
The phone connects to my car via Bluetooth connection to the MMI system. The phone fits in the cupholder, standing upright, in the console between the front seats.
The antennas of both phones are in the top half of the phones according to the manuals.

ok, so the question is why is the 2g over 12dbm less on the z2 than the T. However 3g is working fine.
both phones have antennas in the same area and are positioned identically in the car.
There may be a way to boost the 2g signal in some setting in a hidden service menu but it will drain battery faster.
Have you tried changing the preferred network mode to gsm. I find that in week 3g or 4g areas my Z2 spends too long hanging onto the week data signal before switch to the mode with the better signal strength for calls.
It seems to concentrate on data more than call signal to the point that I have had loads of missed calls due to no signal but if I switch off 4g or set the preferred mode to gsm I get full bars and no call issues but obviously i dont get data unless I change it again. Hopefully this is just a software issue.
