Network bars dropping

Since i installed Froyo i only get 0-2 bars in my house. Was usually 5 bars pretty much all the time. I'm with T Mobile and it was fine for the last couple of months. Was with o2 before that and again was always 5 bars.
It could show 3 bars, then i pick it up and it instantly drops to 1.
Anyone else seeing this?

Did u flash also the new radio?

What's that? All i did was install 2.2 from HTC.

i think the 2.2 (froyo) update will also automaticly update the Radio...
anyone else with that dropping radiosignal issue?
*i didnt recognize any difference @myhome*

DEATH GRIP!
Are you holding your phone right?

Took a quick video.

the signal bars on any phone are meaningless non standardised crap.
for comparisons always use signal strength in terms of dbm and asu. you can see this on your phone. go to menu > settings > about phone > network. that will show the readings in dbm and asu. for any meaningful comparison you need to use those readings as the bars on most phones are garbage non standardised depictions.
or there could be a network that developed recently in your area. there are various signal measuring and mapping apps available which might interest some people. not mentioning them to avoid confusing as it is not needed at most times but if interested then can name a few apps.
@ drew2d1
try not to hold the phone by covering the right bottom corner like you are holding the phone in the video it attenuates the signal more on the htc desire in my experience. seeing the network bars shown before you handled the phone, it looks like you are in a weak signal area and my guess is that the dbm is more than 100 with low asu of 5 or less and attenuation can differ in amounts based on how you hold the phone. i have written a long story about this elsewhere.

I'm right handed i can't use it any other way. I've had the phone for a couple of months i would of noticed it doing this before.
It's T Mobile and I'm in North London so fine on the coverage issue.
I can't send messages when it's showing 0 or 1 bar. It's not dropped a call yet though.
-105 dbm 4asu
-99 dbm 7asu
Stays around there. No idea what that means.
Edit: It drops which ever way i hold it. Even lying flat it goes from 1,2,3,2,3,2,1.

I had the same issue when updating to 2.2 and installing the latest radio. For a temp fix, change the data to gsm, using manual mode. This boosted my signal from 2 bars to all.bars. Not the best solution I know.
Sent from my HTC Desire using XDA App

Already tried that. It's on GSM auto (PRL) now.
Recommendation from bubblesmoney on another forum actually

I'm on 3G and the signal has somewhat slightly improved

same here - signal strength has declined massively since my update. now i get 0-1 bars at home and have to switch on wifi for data when the signal was fine before.
in fact it's one of the reasons that i chose my network because the signal strength was good at home. :-(

-105dbm is crap and a weak signal. minimum attenuation i have ever found on the desire by holding the phone is 4dbm and max upto 20dbm but after earlier update it has never been more than 10-11dbm attenuation and now on froyo update a max of 14dbm attenuation. my phone does not have any case or cover etc so those readings are for such a phone.
you lose the signal at -113dbm as background radiation is same and not distinguishable from signal. hence if your attenuation is 14dbm then you would need a minimum of 99dbm (without holding phone) to have a signal while holding phone. if your attenuation is lesser then you can get away with weaker signal. attenuation differs in each persons hand as absorption will vary in each persons hand.
the following links with posts by me might interest you as i have explored this topic in detail and will explain dbm and asu and attenuation etc.

also i have commented on the anandtech article on the iphone getting a signal till 120dbm. i think the anandtech article made a fundamental error and then said iphone4 antenna is very sensitive in sensing signals till 120dbm unlike other phones. i think that is bollocks due to a fundamental error they made. see page 15 of that article comments section for my comment on this link http://www.anandtech.com/show/3821/iphone-4-redux-analyzing-apples-ios-41-signal-fix see extract from my comment there
"On GSM or UMTS frequencies (between 870 MHz to 2170MHz around the world) used the noise signal floor is between -111 to -114dbm. The signal noise floor is that strength at which the signal cannot be distinguished from background radiation.
The signal noise floor depends on the frequency of broadcast and not the device as far as i am aware. So the iphone cannot have a different noise floor compared to other mobile phones, unless Jobs got the governments all over the world to beam a special signal on a different frequency purely for the iphones!!!!
Anandtech has made a basic error in this analysis i think and consequently this whole article is wrong and meant to favour the iphone either inadvertantly or deliberately.
see post number 57 on the thread in this link for my explanation why this anandtech article is wrong http://forums.moneysavingexpert.com/showthread.php?p=35179785#post35179785
please note that -113dbm (some resources say -111 instead of -113) is the noise floor where signal is indistinguishible from background radiation. look it up in science webpages if you doubt what i say. so if the iphone shows signal to be -120dbm then that is an error. just because it shows a number does not mean that the -113 noise floor value does not exist in physics for gsm broadcast frequencies. http://en.wikipedia.org/wiki/Johnson–Nyquist_noise
see gsm freq bands for the world here http://en.wikipedia.org/wiki/GSM_frequency_bands the freq bands (GSM AND UMTS) used in uk are between 870 to 2170MHz and for that the noise floor is between -111dbm and -113dbm and for the noise floor to be 120dbm the freq would have to be in 180kilohertz which is !!!! and bull as the freq bands used are in MHz so the anandtech numbers dont add up in the 120dbm small print, as there is no 180kilohtz band for gsm in usa or uk as far as i can tell!!!! and 180khz is the freq used for AM band radio and looks like the iphone4 is getting interference from 180khz AM band radio signals too as far i can tell from what anandtech says about 120dbm etc !!! yikes!
I would be happy to be proved wrong and to learn, but from what i have shown i am right! Noise floor depends on the frequency band of transmission rather than circuitry. In the UK Cellular mobile services operate within the frequency ranges 872-960 MHz, 1710-1875 MHz and 1920 - 2170 MHz so the noise floor would be between -114 to -111dbm.
It would be similar in the USA too.
see the rest of my detailed response elsewhere on other forums (post 57 of the thread on the link) http://forums.moneysavingexpert.com/showthread.php?p=35179785#post35179785
I hope there is a response to this comment of mine, from this articles writers or some other RF engineers, as due to the reasons quoted in my ananlysis i think this article by anandtech is grossly wrong. I would be happy to stand corrected if my analysis is wrong.
yes the signals can be sensed at -120dbm but that wouldnt be signals from commercial GSM or UMTS signals, it would be some other signals sensed by the iphone4 sensors and giving a wrong reading of the signal strength. As i said earlier the signal noise floor depends on the broadcast frequency and not the handset, so this article is wrong and grossly so as it is making assumptions of the iphone4 being able to sense GSM / UMTS signals of the order of 120dbm which isnt possible for the frequencies broadcast as per the physics involved. http://en.wikipedia.org/wiki/Johnson–Nyquist_noise that or Jobs and anandtech found some way to defy physics!"

It was fine before i installed Froyo.

Jobs doesn't need to defy physics, he's ok with his RDF

Tmobile, london here. Also experiencing 3g signal drop after update. At home on 2.1 i would have 3 to 4 bars, now on 3g its either zero or 1.

Have been contacting HTC with this problem and got the answer that it is because of the new setup of the cpu speed. They have lowered the cpu frequency and the radio is searching for a signal with the lower power. They have promissed me to fix it. They said that also for this issue they have stopped the froyo rollout and are now under fixing the issues. So expect the fox soon.

What did you do to fix the issue? I'm on T-Mobile (UK) too and as other have noticed a significant drop in signal after the 2.2 update.

I also would be interested in how you fixed the problem. I dropped an email to HTC today, so I will post the response when I hear back from them.

[Q] Question about dbm

I'm using Open Signal Maps to see my connection. Apparently I have -95 dBm thru -104 dBm. I heard that -100 is practically no signal.
I'd also lyk to add that I have seen my phone drop to 1X. I didn't even know that existed in cities. Is that Sprint Version of a GSM phone on 1G? I'm sorry, I'm a previous Tmo customer, where we had 1G(.005Mbps)), 2G(.5Mbps), 3G, 4G. Here on Sprint, it seems lyk it's 1X, 3G, 4G.
I have an attachment of my closest tower. Shouldn't I be way above what I'm getting? The box is me, the circle is a McDonalds I go to. When I'm at McDonalds, my data speeds flourish. I see those 10Mb 4G speeds with full bars. At my house, I only get 3G. And I'm lucky if I get that. Sometimes it drops to 1X. Luckily we have WiFi 10Mb speeds at home.
This, however raises a huge question. Why do I have to be SO close just to get good signal? I mean, the fact that my phone is dropping to 1X means there's something up, right?
P.S. I know it's not called 1G and all that. I'm just saying that for those to easily understand. So you don't have to make a post correcting me.

The Open Signal app is not that accurate add far as location. Many times it would locate my tower in the middle of a lake. Data speeds vary greatly depending on distance, tower traffic, etc. 1x is what we sprint users call 2G.

1X= 1xRTT which is a voice/text network. it SOMETIMES works with web, albeit painfully slow. and just incase you didnt know, the ''G's'' only stand for "generation", so really, you could say 1G=talk, 2G=text, 3G=web, 4G= faster web.

Yea, but I mapped it, lyk looked at the visual and saw a tower there. I understand the whole network traffic and all, but when I go to work, my location is farther, but I still connect to that same tower, and I still get better reception. It's seeming lyk there is something at my house causing my phone HORRIBLE reception. That's the only thing I can think of. I don't know what's going on. -_-
It just seems that all the places I rest, by that I mean hang out, it seems I have no reception, but when I'm at the store or some place random I have great access. The more convenient places, but that's not very practical. This is making me want to break off this family plan and go back to Tmo.

Call Sprint and inquire about the Airave or search for that term on this forum. That device will fix your low signal issue where you hang out and they'll probably give it to you for free instead of lyk losing you as a customer

I know that 4g aka WiMax runs at 2.6Ghz frequency. 3g runs at a much lower frequency. The higher the frequency the worse the signle is at penetrating building and obsticals and is drastically reduced in effectiveness the farther away you are from the tower. See Verision uses LTE which used like 900Mhz i beleive which penetrates deeply into buildings and has a much farther range. Sprint is making the transistion to LTE on a 700Mhz frequency band i beleive which will be the best 4g out. Should be completed by the end of 2013 but i beleive it may take a bit longer than that. As for 3g and 1x getting a very weak signal can led to a tower not having a strong enough signal to support data of 3g. Also some towers are older and havent been upgraded to the 3rd generation of wireless data as a previous poster stated 1g 2g 3g is first, second and third generation techknology. What is weird and doesnt make sense to me ans many other people is that how many bars you have does NOT necessarily coinside with how fast your 3g connection will be. I and thousands of others have learned that even if you have full bars your 3g may to slow as snails and i have had 1 bar to no bars and gotten better 3g speed that certain places with full bars. Some of it has to do with weather, obstacle and how up to date the tower is. Like i said there are still older towers out there that don't even support 3g still. Hope this helpa you a little and im sorry that even pro's i have talked to cant say for sure why full bars and almost no bars doesnt always mean greater and less 3g speed necessarily :-(

Radio comparison - Verizon GN vs Thunderbolt

Both phones set to CDMA EVDO only, no LTE radios active. Location is 3G EHRPD enabled, but does not have any 4G towers for miles. I held both phones the exact same way in the exact same location within 30 seconds of each other to record my results.
Signal Test:
Galaxy Nexus 3G Signal Strength: 0-1 bars, -120dbm 99 asu - -100dbm 1 asu
Thunderbolt 3G Signal Strength: 1-3 bars, -94dbm 2 asu - -85dbm 2 asu
Bandwidth Test:
Galaxy Nexus 3G Bandwidth: 0.86mbps down, 0.54mbps up
Thunderbolt 3G Bandwidth: 2.94mbps down, 0.56mbps up
Bandwidth test was the best of 3 runs using www.speakeasy.net/speedtest connecting to New York, NY. Current location is central NJ.
My Galaxy Nexus is running stock 4.0.4 with the newest radios and bootloader, along with Imo's kernel 2.4.1 exp2.
Honestly, after having my Thunderbolt for 8 months, coming to this supposed better phone and having these kind of radio problems is just appalling. The Thunderbolt was always railed for being the pioneer of LTE radios, and for getting weak signal. Well after these tests I am not sure what to believe besides the truth that is sitting in front of me. My brand spanking new Google phone has by far the worst radio I've ever seen in a Verizon smartphone.
I'm going to be hopeful in getting an update that may resolve these radio issues, but the realist in me tells me this is 100% hardware.
I'd like to get some results from other Verizon Galaxy Nexus users running 3G to see what kind of dbm and bar signal, as well as what kind of bandwidth you guys are getting. I am very disappointed and want to know if it's a hardware defect or if this phones radios' really are this bad

Meh. The Qualcomm radios in both of these phones are in fact ****. I think the build of the Galaxy Nexus (whether it be physical or software) has something to do with it. Maybe Samsung herp derped the position of the radios or Google took a **** on the blobs.
Regardless, its a great phone and still gets better data speeds than every other carrier and phone. -coughs- iPhone users -coughs-
Sent from my Galaxy Nexus using XDA

Except it doesn't get the best data speeds of any other phones, as my test results conclude.
Even on 4G I've nabbed 40mbps down 15mbps up bandwidth tests on that same exact Thunderbolt when I was in a good signal 4G area. How much have most GN users hit on 4G? 30mbps down?
This phone is a great micro-tablet, but as a phone it is heavily lacking.

Really, cause I have seen people getting upwards of 50mb/s on the Nexus (seems like most of them live in NYC).
Not to mention I was talking about people on other carriers.
Sent from my Galaxy Nexus using XDA

Other carriers is a given, but that really isn't what the point of this comparison is. The point is I'm holding two phones on the same carrier, at the same time, the same way, and one performs multitudes greater performance than the other. Has nothing to do with other carriers.
Fact is this phones radio is junk. You can have a quad core 1080p Super AMOLED Plus screen and 2GB of RAM, the best GPU on the market and 128GB of space, but if it can't hold a signal to save YOUR life, then what good is it at as a phone?
Samsung/Google needs to get on this right now and fix this phones radio. I'm just worried that it can't be fixed through a software OTA...
And I'd also like some speed comparisons, namely 3G, from other Verizon GN users if possible please.

On 3g i used to get about -75 at worst with thunderbolt at my house. Currently getting -93 at best with two different galaxy nexus. Usually worse. Used to have a stable 4g signal too. Now it drops after a few seconds

That sounds about right... very disappointed in these radios.

I get the same -120dbm, 99asu with my Nexus at home, where I would get around 95dbm on my old Tbolt. I think the antenna/radio gives up signal quicker at the fringe distances faster on the Nexus - if I go into a city I get the signal strength I am supposed to get. I have a theory that part of the problem may lie with Verizon's use of old Alltel towers (I'm on the VA/NC border) - The signal in my area is consistently weak, but I've gone to other rural areas & gotten good strength. Perhaps Samsung/VZW will give us a software update on the phones...and perhaps when they upgrade our towers around here for LTE it might straighten up the tower's overall firmware...But we probably wont get LTE here until 2020.

[Long Term Review]Wilson Electronics DB Pro 800/1900Mhz Repeater

I have been using the Wilson Electronics DB Pro Adjustable Gain 800/1900Mhz Smart Technology II Signal Booster http://www.wilsonelectronics.com/store/display/40/46/db-pro for the better part of a year now.
The unit comes standard with an indoor antenna and an outdoor omni-directional antenna. A directional antenna can be substituted at a cost for even more remote rural areas. It comes with all mounting hardware and 3 lengths (20’, 30’ and 50’) of coax cable.
I opted for the omni-directional as I have a nearby tower but it seems I am in a black hole for service. I mounted min about 40ft up on a TV Antenna tower after removing the obsolete UHF/VHF Antenna.
Before using the unit I only ever had 0-1 bars of service in my home and very low data speeds.
I first used it on Verizon Wireless and found my signal strength to go from 0-1 bar (-100 to -120dBm) to an average of 4-5 bars (-65dBm to-85dBm). My data speeds more than tripled from an avg of below 56kb/s-100kb/s to around 500kb/s down +/- with an upload at approx 1.2Mbps.
I get similar results on Sprint since switching to them. Both the VZW and Sprint phones are the Samsung Galaxy Nexus.
This particular unit only boosts the 800 and 1900 Mhz bands so the VZW 4G will not be boosted. The Sprint 4G however would be since it is 1900 Mhz band. Call quality is great compared choppy and dropped calls I had prior.
My nearest tower is 5.7 miles away and the other is about 14 miles. Back in July 2012 my nearest tower to me was down for weeks and this little unit reached to the 14 mile away tower without loss of signal or speed.
I recently had an issue with the device where the 1900 Mhz band stopped working at maximum. I contacted Wilson Electronics Technical Support Representative Juan and he set me up with an RMA to send the unit back after a few emails to fully explain the issue (if only our carriers were this pleasant to deal with). I received quick replies to my questions and he was a pleasure to deal with.
The new replacement is already on its way back now. I have no doubts that the unit will be as flawless as the first one.
If you have a low signal issue from your CDMA or GSM cell carrier (they have GSM models as well that service other bands) I would highly suggest this repeater.
Good build quality and excellent customer service are well worth the price tag.
It is relatively easy to set up and once it is set up you should never have to mess with it again.
What carriers don’t tell you is they only guarantee service if your within 5 miles of a tower on avg. If your outside that range you get an “I’m sorry”.
That’s where these folks and these wonderful units come in.

The replacement is working like a dream

Tmobile and 800/1900MHz antenna booster
I am looking at purchasing this. It gets good reviews on Amazon as well but I am wondering if it will help my data connection on tmobile - I think 4g is on 1700MHz, so I am wondering if this antenna would help at all or just improve call reception.
Any info is appreciated - thanks

Nice, I was thinking of picking up something like this but unsure of the performance. $500 though....ouch!

Cellular strength and throughput

We know how much you like to stream, ahem, "videos", and so cellular data is mega-important. Rate this thread to express how you think the Samsung Galaxy S8+'s LTE performs. A higher rating indicates that it's fantastic: throughput is excellent and signal strength is top-notch.
Then, drop a comment if you have anything to add.

I get a low 4g signal at work whereas on my s7 edge I didn't get anything

Mine is a lot better than any phone I've had before. Usually at home on all my other phones I have 1-2 bars and on the S8+ I have at least 4 bars.

Bars are no indication of true signal strength. My S8+ doesn't get nearly as strong of a signal as my Pixel XL. I drop signal a lot more often now. I was rather disappointed with the performance of the cell radio actually.

For me, the signal is about the same at home. But at work, the S8+ performs much better than the Note5 that I had... Must be an extra band or something. The Note5 would hang on to an unusable LTE signal or drop to 3G/1x inside my job. The S8+ stays on on LTE with a usable signal.
Sent from my SM-G955U using Tapatalk

It's worst Then S8 as I used that before shifting to S8 plus. But download speed is great.

My S7 was better. The S7 ised a new duel antenna tech, I am not sure the S8 used it or not.

My AT&T Note 4 and my new S8+ get about the same signal, which is really disappointing

I generally see around 5-8dbm better then I did with my pixel xl at home..notice the s8+ does drop signal little easier tho then my pixel in fringe areas

Tested right outside my house. Never had these speeds on my Note 5.

Comming from a S6, the signals and speeds are far better, also my s6 was missing a few bands so never ever got speeds like this on my Jio 4G Network in India

At work on LTE Im getting 31 Mbps down and 6 Mbps up. Not bad! Faster than our company wifi!

Poor Reception in Canada on Bell Mobility
I just got an unlocked S8+ that was apparently originally from Sprint (because that is where the home page goes in Samsung Internet).
I do not get very good reception on it – even in urban/suburban areas. Sometimes, when I am inside a building, it disappears altogether. I often get 1 or 2 bars on the reception indicator. If I check the “Sim Card Status” screen under settings I get -105 dBm 3 asu. I don’t really know what those numbers mean.
Is there anything I can do to improve reception? Should I be calling Bell and maybe they need to know what kind of phone I have? Should I expect an S8+ purchased directly from Bell (they also carry this phone) to have better reception? Or is the reception of “105 dBm 3 asu” fine and it’s just the indicator showing low levels?
As much as I like this phone I cannot be missing calls randomly. I have a business to run.
Thanks.

Hey fish you want it down, the dBm i mean. Here's a quote "-50 dBm is great signal or full bars. -120 dBm is very poor signal or a dead zone." you at 105 dBm is garbage, no wonder your missing calls.. Since you are experiencing network issues, you could get a replacement, but i don’t think it will make much difference. as it's all same hardware. Why not get a Google Pixel XL i heard they got awesome reception! Or if you’re at home a lot, purchase an lte repeater booster ? Problem Solved!

Hey fish you want it down, the dBm i mean. Here's a quote "-50 dBm is great signal or full bars. -120 dBm is very poor signal or a dead zone." you at 105 dBm is garbage, no wonder your missing calls.. Since you are experiencing network issues, you could get a replacement, but i don’t think it will make much difference. as it's all same hardware. Why not get a Google Pixel XL i heard they got awesome reception! Or if you’re at home a lot, purchase an lte repeater booster ? Problem Solved!

I went through a whole “carrier switching” routine (details found somewhere on these forums) and after changing the CSC to Canadian I flashed Bell Mobility's firmware. The phone now shows that it’s an SM-G955W which is the Canadian model. And apparently now supports additional LTE bands 29(700) and 30(2300) which were missing from the SM-G955U (I determined this by dialing *#2263#).
I have no idea if it *really* supports these bands or just *says* that it does but my gut tells me that it really does support them. I suspect that the hardware for the SM-G955U and SM-G955W is 100% identical and any differences are controlled through software only.
And I seem to have better reception now. I am getting 4 to 5 bars in most places and under -100 dBm in most places. Plus Wi-Fi calling works now so I have reception in my basement at my house.
The true test will be when we go camping next summer.
