Hello whenever i put my Tilt close to my computer. my computer speakers start to make distorted and crackling sounds .. Same thing with my Car. I use an Ipod connected to my tape player, whenever i put the tilt in the cup holder next to my ipod, it starts to make my speakers crack along with making a weird distorted sound..
Does this happen to others?
Is this your first GSM phone?
-McMex
Same thing happens here. I can turn the volume all the way down on the speakers and it still will make a racket (putt-putt-putt sound) through them when near them.
I wonder how much RF radiation is going on when this happens?
Fwiw, my DSL wireless router had a warning to keep at least 8 inches away from it when on.
I believe this is caused by the RF of the Tilt (or any GSM phone). Sheilded speakers usually keep this to a minimum, but they're still affected. Really cheap speaker sets seem to be affected most.
Disclaimer: I'm no expert on electronics so sorry I can't go more in depth.
It has to do with the way the TDMA technology works behind GSM. There are bursts of RF transmissions taking place within a specified frequency. If your carrier has 3G systems in place that use WCDMA (spread spectrum) then you will not have those buzzing sounds at all since CDMA (sprint/verizon) and WCDMA systems like AT&T's 3G system are based on the fact that the handset transmits/receives on a range of frequncies thus there are no bursts of RF since the RF channel is now 12 or more MHz wide. Read up about how the technologies work. I can tell wether I am on the GSM or WCDMA system here on At&t without even looking at the phones icon to tell me by if I hear the buzzing or not. lol
Typically the GSM side of the cell operator has better signal in more places since it's on a lower freq which travels farther not all the time though. The other factor is since CDMA transmits to your phone on a wide block of frequencies, the towers generally have to be closer together to provide a high S/N ratio. So in places like a bunker or elevator the 3G signal may not be there whereas the GSM will be. I can be on 3G all day but then go into an elevator shaft and the phone no longer hears the 3G 1900 MHz signal but hears the GSM signal just fine so by the time I am out of the elevator the phone has dropped to GSM.
This is just what happens when the phone is near any kind of speakers or what not. It is when your phone is in GSM mode. EG: Edge. I don't know why it does this, but I learned a long time ago how to deal with it. Plus the kaiser has 3G so just make sure it's on that network and you shouldn't hear that noise anymore.
I use to be a Medic. This is why people are asked to turn off cell phones in hospitals. The signals from our phones will effect other electronic devices. Sometimes the effect will never present itself other times it's obvious like with speakers. My partner on the ambulance and I discovered that if we put our phones on or near the dashboard that the siren would turn on whenever we got an incoming call or message. That caused more than one embarrassing moment
I had a Motorola V3 Razr previous to this phone, and I could not have it within two feet of my work computer, but with my Tilt it is less than a foot away and I don't have static when it rings or goes online to check e-mail. I have been pretty impressed. Also since i flashed the the new radio 1.27.14.09 I have had even better preformance.
Google "GSM buzz"
Also just as fun is placing the phone (in GSM mode) near a HDTV receiver, it will cause the TV signal to drop when a call comes in.

Hello,
my kaiser continuously makes zz zzz on stereo speaker.
It disappear if I make a soft reset (sometimes).
There is no active connection (also disabled with NoData), and no active phone call.
It happens with Hsdpa enabled/disabled.
I tried also to phone off and then phone on again... but problem remains.
What can be???
And what can I do??
I think also during zz zz it make radiation as during internet surf or during a phone call...
It just sounds like static/electrical interference. Are your speakers of higher end quality or are they your normal department store speakers?
The only thing you can do is to move the phone away from the speakers to minimize any interference or to shield your speakers.

Sure,
but I usually use this phone with 2 sim cards of different network providers. This happens only with one SIM! It seems as if there is an hidden connection... but using the same SIM with other phones doesn't happens anything!!
It's really strange...
I suppose also that this continuous connection drain my battery down and cover me all day of unuseful radiations!
I too have seen this with my phone, it comes and goes, soft reset doesn't seem to have anything to do with it, just seems like a bad connection. But if your sim is causing it then it might be related to an interference, please update if you figure it out.
It's my understanding that cell phone technology works in different frequency bands. And within those bands, certain frequencies are designated for specific carriers.
Assuming all of that is true, that could explain why you get interference with one sim card and not the other, because the frequency that the quiet sim card is using is either above or below the range to cause noise.
But keep in mind that my understanding of everything could be wrong so it's probably best to do some research to see if you can come up with a more definitive answer.
Btw, what two carriers are you using?
I checked better and sometimes it happens also with what I thought to be a quiet sim card. So I can believe it happens with all operators.
What is strange is that with this two sim cards no other phones (gsm, umts, hsdpa, ...) makes noises on stereo speakers... at least not during standby mode.
I can see that my battery drains down only when phone is enabled (and not in use). If during all the time phone is on it makes noises... it would mean that phone is used to exchange continuously some data with provider but without any connection.
It seems like that TYTN II wants to know if there is a better signal for example to cross from GSM to HSDPA mode.. or something like that so that it tries all the time to exchange data with provider! But this drains battery down and develops radiations!!!
As far as making and receiving phone calls, do you use 3g? Any phone I've ever seen that uses 3g absolutely sucks. My dad's phone, my mom's phone, my girlfriend's phone, my phone. What happens is the call either doesn't go through. If you listen to the dial tone it has a small click right before each tone, if I hear that, it mean's the call isn't going through.
My mom and girlfriend have gone through replacements on their phone, but the 3g still sucks. I've even noticed they don't get that great of reception.
Even on my Tilt, if I switch to 3G i only have 2 bars and apparently people have complained of calling me but I never received the call. Now with Edge, I have full bars, and no one ever complains about the call not going through.
So what's your guy's take on 3g?
Similar to what you've experienced. I generally leave mine turned off the majority of the time, since I have the WiFi running when I'm at home anyway. I turn it on only when I need to browse the web or something when I'm out and about.
Not to mention the immense battery drain that 3G demands. My battery life is dramatically better on Edge as opposed to 3G.
Your provider needs to update/fix their network. This is not a device issue, it's a network issue. Proper 3G (well, 3.5G / HSPA, not just UMTS per se) should also use less power than GSM / EDGE for transfers... (in watt/kbps, though)
I know for a fact that all devices in my signature (that support 3G) can work perfectly with 3G on a proper network.

I don't experience network issues as bad as the OP seems to have, but I've always had terrible battery life on my Tilt and my iPhone, my two most recent 3G devices. My 8525 was actually very good on the battery with 3G running all day long, never had a problem getting through the day.
Maybe the intermittent GPS usage on the latter two? I don't know.

I should go in and ask them about it, just to see what they say. Ask them why the new and greatest 3g is worse than edge. I have AT&T, I live in Washington, and I live right by a Cell tower too (only a 2 or 3 blocks away from it).
I woudln't mind using it for data but the fees here are prohibitive for private use. We use it on our work phones for data and it works well on Telstra.

They'll probably say it ain't so Thing is, when 3G first got rolled out here, we had much the same issues. The big providers here spent some $$$ to replace "faulty" hardware at the towers, and voila, the problem disappeared (2 years ago?). Seems many 3G networks around the world have similar issues to the ones you described in the opening post. I have a sneaking suspicion that one of the 3G cell-tower hardware manufacturers - probably the cheapest and hence most used - makes some really crappy equipment. I could almost imagine that manufacturer is Qualcomm
In all seriousness though, all I know for sure is we had these issues here too, and they fixed them by fixing the towers. (Though of course there is some difference between different devices and how well they do 3G)
From talking to some guys at work Telstra's 3G network has been pretty much flawless for them asides from cost issues associated with Telstra.
I live in indonesia and never have any problem with 3G,. , the only problem is, its expensive,. lol,.
I am in NZ
No problems with 3G whatsoever. Have Imate JasJar - loving every second of it.
New Jersey, USA
3G has always seem pretty good around here in New Jersey with AT&T, but I'm 25 minutes from New York, so imagine how many towers they have on the tri-state area (New York, New Jersey and Connecticut). Very rare to lose 3G reception (exept on the iPhone 3G that everybody complains about losing it often). But important to mention also is that Kearny, town where my sister lives, I lose reception a 100%, my phone's reception just dies, and when I switch it to GSM instead of 3G...voila. Full signal strenght.
wow.. the results turned out quite different than I imagined.
Obviously it's just in my area that 3G sucks. I really wish they would fix this, considering that every phone released now is 3G...and you think someone would notice... well, I'm sure if I wait long enough people will start to notice, but who knows,
I can't remember the last time I had problems with 3G. though I remember before Cingular got bought by AT&T and they were just rolling out there 3G, I used to have problems then, I guess it was due to them configuring/re-configuring the towers. I think the engineers were just going by what the manual said, which weren't the best settings for each area.
I'm on 3G all day everyday on the hour and it's good. even when I'm in the basement and have 1 bar I still receive all my calls and I can make calls. though on this 1 bar I sometimes have to repeat myself every 1.5 minute, but I don't complain about that because it's 1 bar and I'm in the basement. at my friend's apartment I'm the only one that get signal, nothing else work there, not T-Mobile, not sprint, not verizon, not alltel, not vergin nothing else only AT&T works and I get 3 bars of 3G there. I always laugh because he has to leave his phone by the window and use his blue tooth.
I honestly don't think you're by a 3G tower because you should be getting way more than 3 bars. also ask them about the issue you're having AT&T is a good company they will listen to you. call them and open a ticket (before this they will have you go through the basic steps, restarting by removing the battery, etc) tell them you've done that multiple times and yet you have the same issue so it must be a network issue. have them escalate the ticket (they will send an engineer out and he/she will call you, they will work on the towers around your area). don't forget to be polite, no one likes a hot head.
in roughly mid year last year I was only getting edge at my job even though it is a 3G area. at home inside my house had full bars, so I called them up and they worked with me. the engineer stayed in my area roughly 2 weeks to deal with the issue. after that I've had 2 bars of 3G in doors at my job.
Hi all, I'm wanting to know if anyone else seems to be experiencing an issue where during a call the signal icon will change from H to G and the quality of reception / voice also drops to what resembles a non-3G phone.
This seems to happen quite often regardless if the call is inbound or outbound. I can be sitting at my desk and have what appears to be full reception with the H icon, then 2-3 minutes into a call (still sitting at my desk) the icon will change to G and from the quality degradation it must be reducing to 2G... why is this? I could understand if I was walking around but it happens regardless and will never go back up to H during a call only once the call has ended... is this a limitation of the cell network/carrier?
I'm using Dutty's v4, radio 1.09.25.23, Olinex 1.93 hardspl. Network carrier is Optus and I'm located right in the middle of the city - Melbourne, Australia.
I'm wanting to try some of the newer Raphel radios but need to get Security Unlocked first - already PM'd Olipro... just waitin
Any comments ?
Hi,
Same problem to me... downtown of the fifth biggest city in France...
Don't worry if I may say so: the phone is the problem. it has crappy reception, probably the crappiest of all time... I have tried any possible Radio ROM available, none of them changed a signle thing...
Worst HTC phone ever made for reception... All my friends with way cheaper phones have at least four to five bars when they are at my place, I don't get that... but all my other phones do.
Eve worse: the phone totally disconnects from network when I have one or two bars of H or 3G... I receive NO phone call, no SMS and I am notified two days later (30 voice msgs, fifty SMS... all sent two days ago). I even had issues at work becaus eof all this, people complained they couldn't reach me for hours and days...
I now have to set it back to G alone (switch off H or 3G that I want to use all the time...), which is a shame for such an advanced device...
Correct me if I'm wrong, but you're not supposed to get a H during calls, maybe for video calls, I'm not sure. But for regular 3G calls, you shouldn't get a H, H should only appear when there is data transfer, like when using Internet for example.

I'm not really qualified to comment except from my own experience... My phone always has the H symbol, when there is no data activity then the H symble is faded/semi transparent and becomes solid as soon as I make a call or transfer data (eg. updating weather) and I never have the 3G icon - always H or G. I belive this may be related to the operator and the frequencies they use for both HSDxA and 2G modes.
Probably for about 80% of my calls I'll keep the H symbol, but when it drops to G it's really annoying as the quality turns to sh*t
My phone never seems to be able to hold a signal.
I'm on the 3 network in Australia & my phone doesn't stick to the network. If I choose options under the phone and press 'find network' a couple of times it will lock on, but then minutes later I get the 'searching for network'. Over & over again.
My phone is unlocked using the Olinex method, my radio is current & I can't even recieve incoming calls or texts...outgoing is fine (when I've got network0 & I can use browse the internet & use GPS etc...just nothing incoming...
i have a theory on this its called " crap design"! i thinks its because the internal antenna is towards the bottom of the device so when you hold it you are covering the antenna.
try holding the phone with just two fingers trying not to cover the back (below the battery ) this works for me! i only say this out of observation
Could just be the way the network is configured for HSDPA. Voice traffic can be pushed on to 3G (or release 99 as it is sometimes called) to reduce the loading on the HSPDA carrier / layer.
See it as a good thing
Most handsets I have owned usually drop from HSDPA or 3G or GPRS during a voice call, probably just a design feature to save battery life. Should latch back on after call though. I have to say though, I had the MDA compact IV and the reception is positively shocking! dropping signal is soon as I picked it up and i'm in a good signal area! On its way back to T-MO as I speak as this wasn't the only issue. Shame, great form factor as well.
Symbols on your phone are just that symbolic, they don't always mean what you think they mean.
If a UE is on your desk in idle mode and it looks like you have a great signal and a H displayed, great. It means that it is measuring the quality of the network and you have the ABILITY to hold a HS data session should you want. The reception barrs on most 3g UE's aren't a measure of the radio reception but of the amount of noise. More bars less noise, less bars noisey environment.
If you make a voice call, there is no way any decent network would use HS to carry your call as it is wasting resource somebody else could use and of course pay for. Once in a call the UE has to monitor many things and also maintain that call or data session. In simplistic terms if the conditions do not allow the call to be carried over 3G it will step down to 2G. If it was a data session it could go from HSDPA to 3G, then 3G to GPRS.
Also a network could easily by the swap of a 1 or a 0 carry your voice call over 2G without you knowing at all, freeing up that 3G network that cost billions to roll out and pay licence fees for, for data which they can charge more for.

I think they made a mistake in the International English manual where it says the antenna is located at the bottom. Either that or it's different for different regional phones. If you download the HTC Touch Diamond_Asia_English_Manual_Manual_080521.pdf or HTC_Diamond_User_Manual_Asia_WWE.pdf from HTC's site, it shows the antenna being at the top next to the camera.

The operators do not do this. Do they switch you to a land line when you call a land line, no. It is all down to radio quality where you are making the call and not what number or type of line you are calling. The phone networks are not that intelligent

Actually, they are, they know what types of numbers you're calling. This is why even for long distance prices, there is a different between calling a land line and a cellphone number. Either way, the system can tell what type of line you're connected to.
I use my nexus one on ATT - in my area, there are two antennas.. ATT's "preferred" antenna which barely gets any signal at all (resulting in dropped calls every couple of minutes), and there's a "roaming" antenna which gives me full signal and works great. The problem is that when I'm on the roaming (good) antenna, the phone gets a tiny bit of signal from the "preferred" (bad) antenna, switches me over then my calls drop.
I had a Palm Treo which had a hack to manually select the antenna I wanted to use, which worked GREAT. Does a similar hack exist for the nexus one/android?
interesting.... didn't know we can select antennas
there should be a way to hack radio module to allow cell tower override, i have exactly same problem. there are three cells around my house, one nearby and two far away. for some stupid reason phone switches to different cell tower and i lose my network.
in battery use, i have cell standby as my biggest battery hog. cell standby over 25%
I'd be willing to pay for this hack.
has anybody ever found a way to do this?? I just moved further out into the country to get away from the city, and i am one tower too far away to be in the local calling area to all my contacts. lol and i know I'm BARELY into the other towers coverage area. So, if i could tell my phone to stay locked on to a particular tower, and actually get a signal (It switches towers when i still have 3 bars of signal, and I live about a mile further down the street from where it switches) I can avoid long distance charges. I haven't been able to find anything anywhere to be able to do it, but I may be using the wrong search terms. I'm not completely up to snuff on most technical terms. Thanks in advance.

U could very well be correct! Sounds logical. I've been exploring a handful of VoIP options that ya can use from your Android/WM device using your Data connection/WiFi.
I spent a bunch of time reading and researching, and just installed one called Nettalk. No local phone number for incoming calls, but the app is free, and u can make calls to anywhere to/from any Canadian area. The app looks just like the regular dialer, and works pretty decent. So, when somebody calls, I'll just select 'reject call with message' (if calling from a cell) and say I'll call rite back, or if calling from a land line, I'll just send it to voicemail and call back and presto... problem solved. There are a few other options available, where u pay anywhere from $5 a month, to $30 a month and you still using your Data/WiFi connection, but u get a local calling number for contacts to call, and doesn't matter where your phone is, it will receive the call free of long distance charges. Problem is, i haven't found any that have the city I'm from in their numbers database. So for now, I'm going to see how this system works out.

Both the handset and the base station "handle" hand offs. The handset has a programmed minimum signal level, below which it will essentially request a hand off if one is available. The network can switch the handset to another tower for load balancing or other reasons if it determines that the handset (or the carrier's business interests) is better served by another tower. It's a two way system. If the network wants to move you on to another tower, but the phone won't get a lock, you stay on the original tower.
The problem with the OP is that his SIM (which is programmed with carrier preferences) keeps pushing him off roaming and into the actual AT&T network. Basically, AT&T has its network set up so that any level of AT&T signal is preferable to any level of roaming. It does that to save money on roaming costs, since AT&T handles you for free while you're on their system, but has to pay a few cents to have the roaming partner host you.
Maybe
I think Tasks can do that.
samsung has that feature but i have to find for other handsets
Hi guys, I just got my Incredible S yesterday, and I absolutely love this phone!! The only problem so far is the fluctuating signal bars. I'm not sure if this topic has been discussed here, but it seems to me that when I hold the phone...my signal gets weaker. When I put the phone on down..the signal gets stronger. Does a rubber or silicone case help as far as limiting signal interference?

I'm talking about 3G/H. It's such a shame. I really liked this phone, but designing the antenna on the battery cover is a huge flaw. What were they thinking?!!??
I also have the signal strength fluctuations. I have tried everything: changing the SIM card, changing operators (Swisscom and Sunrise), changing settings GSM alone, WCDMA alone, and GSM/WCDMA auto, and soft reset. The only thing I have not yet tried is a hard reset.
I wonder if somebody else has the same problem? The consequence of this problem is that often times the quality of the calls is lousy and/or the calls are dropped.
Please help me..
Have to say, my signal level is dreadful compared to my bog standard Nokia mobile phone in low signal areas, I get no signal on my Inc S while 2 or sometimes 3 bars on my Nokia. It's really spoiling an otherwise brilliant device. One thing I was wondering is if changing radio from the 22_M to the 27_M might help, anybody know what the difference between them is ?
and, data does not work over 50% of the time on gprs, but fine on hsdpa/3g/edge, don't know if that's also down to poor signal reception ?
I had the same problem with my IS. when the internet connaction GSM/WCDMA auto i had many unexeptable call ends. I put the internet connection to GSM only and every thing is ok. Acording to info i have the problem is in some operaters new software when the network type changes the telefone cannot change it normaly.
After visiting other fora, I have a crucial question to ask: is the reception problem (fluctuating bars, dropped calls, WiFi disconnecting) a generalised problem, or, rather, is my phone faulty, and therefore should I have it repaired?
HTC update the radio module immediately....

I also believe that the desire s has this same problem they are similarly designed devices now running with very similar software.
even though at times signal can be great without moving it can drop to nothing and I'll lose all signal, which I believe has caused me miss several calls as they've gone to voicemail rather than ring on the phone.
I'm hoping that an upgrade to the phones radio will fix/improve this over time (the optimistic outlook)
Sent from my HTC Desire S using XDA Premium App
signal
its the antenna design =Fail , put it flat on a desk and dont hold it and watch your signal go up pick it up and its like an hour glass going down
I am now arriving at the conclusion that sound quality and dropped calls (and bars fluctuating) can be explained by a connection problem when using GSM/WCDMA Auto. The problem disappears when using GSM Auto. Any views?
Same here, but it is better on "wcdma only" either. I'm suspectinig it has issues only when switching between wcdma and gsm
