Signal strength at 48% from MyPhone anyone get higher?? - MDA, XDA, 1010 General

I'm using an XDA (T-Mobile PPC with 4.01.16 and RSU 6.18.00). Using MyPhone software that I just started using today in my room I get 48% (average) signal strength. I do not really drop calls here so this is about the best signal I get because drivign around I drop calls and break up ALL day. I mean honestly, the phone might as well not even work if I'm not in my room. Now when I bought this phone (on eBay of course) it does not have tha black plastic that covers up the antenna and holds the stylus in place. Now I don't know if this is causing it but this things about as useful as a tin can with string for a phone. Anyone else get % like this? I'm in Florida btw. Let me know. Also, does the XDAII get better reception? TIA

when i used that free program which show it i would get 108% most of the time and places where the reception was poor about 48%

XDA 2 signal
im using that freeware too, my signal reaches 105% at high levels and 56% at low levels, below that it's RED already.
48% man, thats low, or maybe its a programming diff. between XDA 1 and 2, guessing.

could it be because us have more CMA and gsm850 covering then gsm 900/1900 ?

I'm dying with this signal. I'm getting ready to just straight chuck it out the window. You guys think it has to do with the XDA II and the different band? I was really wondering how people using an XDAI got reception. Perhaps this is just a bum unit, I'm not really sure. If thats the case its going right back on eBay and I'll pick up another one. Anyone with an XDAI have good reception? This is actually the worst reception I've ever had on any phone. And I had that ghetto MetroPCS when it first came out and I thought nothing could compare....but this is EXTREMELY terrible. I used the Nokia 3620 before this and it had great reception so this is a big change. Let me know...tia

are you having any issues apart from the signal measure tools saying that it's 48 ?
i mean if you can call and recieve calls without problems does it really matter what the program says ?

Yes that is the problem. I'm having horrible signal strength. This phone drops calls all the time, it breaks up if it does not drop them. The only time it works if you do not move. It certainly takes the "mobile" out of "mobile phone". Any other advice?

Signal strength
Have you tried upgrading your ROM, thry this link and have a look:
http://www.my-xda.com/downloads/xda2_upgrade.html

thomo: yes I'm using the newest rom available from T-mobile (4.01.16 I think). I was wondering if maybe I should try the unofficial RSU that is on yorch.net. Anyone else using this RSU? Can I revert back to an old radio if I don't like that one? I know radio upgrades are kind of risky business.

Signal boost

Hello,
Does anyone know of any antennas or other physical devices that I can use to boost my cell phone's signal? In my apartment in Connecticut, I drop calls all the time while talking but it doesn't really happen anywhere else so I only need to improve the signal in my place. I remember I used to have an actual antenna for my old Nokia phone that would stick to the outside of my car. Also, I once had one of those signal boosting stickers that went on the back of the phone.
If anyone knows of any reliable way to boost the signal on my T-Mobile Touch Pro 2 in Connecticut that doesn't involve flashing a new radio, I'd appreciate it. Thank you!

Did you wait for the sticker to boot up?
Check these guys out
They seem to have solutions for all cellphone applications
Cellphone-Mate looks reasonable.

let me know how it works! haha
maybe try a different radio?
I know Best Buy sells signal boosters but i remember them being a bit expensive.
unfortunately our devices don't have an external antenna jack, i know the kaiser (original tilt)
Thanks guys.
As far as radios, do I just keep trying one by one until I see an improvement? Is there one that is known of that is stronger than others? The Fuze forum has a thread with people's results voting for which was best. Nothing like that here.

Yes, exactly...you'll need to try out the ones that are available for your model, and just see which one gives the best results in your situation/location. You can read votes and recommendations all day long, but they can have no relation to what results you will see
THIS thread has the complete list of radios available for the Rhodium
Unwiredsignal with a Desktop kit 801247
You can try a Wilson desktop cell phone signal booster. It might work for you. I have one in my home office... (basement) and it covers that area only (20x20) so I think it would be perfect for an apartment. I havent tried it in a larger area, but Unwiredsignal.com says it will cover a one to two room area. There is no physical connection to your phone.
Hope this helps...

Both ATT and TMobile offer microcell. Trialing in various areas.
It uses your existing broadband connection to relay calls to your phone.
Looking at ATTs' website it appears to be $150.00 for the equipment.
Here is a link.

Thanks a lot guys. I'd hate to have to pay 320 for the one on Unwiredsignal.com but I'll look into it.

[Q] Losing signal through call

I am losing a signal half way through a conversation and i get cut off ,i have checked it a few times today by calling mates when the phone strength is 2-3 bars ,after a few minutes i get cut off and the phone has lost signal .
Any help with this please ?
I have looked at radio codes and flashing roms but unsure as to what they mean or do ,i am on O2 and the signal is ok where i live and worked ok on my last phone SE k800i ,just seems as though the hd2 is constantly losing the signal and trying to find it but them comes up with 2-3 bars
I am new to all this stuff so please explain it to an idiot in simple terms
If you are having signal issues, flashing a new radio could do a lot of good. The radio ROM is the software that controls how your phone connects to the various network signals. You may have to experiment with several different radios before you find one that works well in your area. Read THIS thread for more information on it.
Another possibility is if you are only experiencing signal problems during calls, it may be that you are holding the phone in a way which degrades the reception of your antenna. Some users have reported that holding the phone tightly at the bottom (where the antenna is located) causes a slow loss of signal. If this is the case, try gripping your phone nearer to the camera at the top.
Cheers for the link ,will have a read through
+1 faelock. if you hold the phone with the bottom pressed flat into your palm it can make a difference of as much as 2-3 bars.
Does anyone know if these make a difference ,as i have trouble with signal around the house but full signal while outside

I've seen those sold for years, but I really don't know if the boost signal. I used 1 once that came with a combo thing I bought on ebay, but didn't have signal problems to begin with.
You could look for signal repeaters that can be purchased that boost signal in the house. Over here in the usa, I know that sprint and at&t have them and you can get them free if you complain about signal strength in your house.
Those "signal boosters" are about as effective as kinoki foot pads and ionic bracelets. I had the same problem when I frist bought my phone. No signal or 1 bar in my bedroom but walk outside the door and I got 2-3 bars. After flashing a new radio I now have full bars everywhere in my house; so that would be my suggestion. If you're nervous about flashing and would rather go with a signal booster than check out THESE ones that apparently work.
Thanks for the reply guys

the best way is to just test them out. What works for me, might not work for you. Since you have the Euro HD2, I'm pretty sure you can use any of the radios out, .50 and .51 radios.

[Q] 3G Reception Thread

How is your 3G reception on the Vibrant? I just purchased a Vibrant as a replacement for my aging and bluetooth handicapped G1 and I am disappointed with the 3G reception.
T-Mobile's coverage in my area is moderate, and the G1 has been able to hold on to a 3G signal in most locations. Typically, at home the G1 will hold on to 2-3 bars of 3G, and at work I am lucky to get 1 -- usually camps out on 2G with 4 or 5 bars.
The Vibrant pretty much always shows 0 bars of 3G while indoors, and may even flop back to 2G. It is fairly consistently on 2G in my home at 2 bars and at work I can only get 1 bar of 2G with this phone and spend the majority of the time with no signal at all.
I sat down and did some comparison between the Vibrant and the G1 and have found the following:
1. *#*#4636#*#* menu shows significantly worse signal levels on the Vibrant than on the G1, often times showing 0db and 0asu in the same location I am seeing -89db to -101db 3G on the G1.
2. The service menu on the Vibrant indicates a signal level which on 3G is fairly consistently 8db better than the one shown on the info menu. Interestingly, 2G signal levels as shown on the service menu seem fairly spot on with those shown from the info menu in Android.
3. The service menu 3G signal levels on the Vibrant seem consistent with those that I see on the G1 with a variation of perhaps only a couple of decibels.
That said, it seems interesting that battery usage on the Vibrant seems to indicate nearly 60% of its time with no service under cell standby when I get 0% in the same location with the G1. I am wondering if the time being recorded here is in fact the time spent with 0 bars being displayed even if the phone does, in fact, have a signal.
It is apparent that there is at least a software issue with the display here, as has been concluded in prior threads. However, ignoring the bar display I am wondering what others feel of the signal coverage with their Vibrant versus their old phone?
Does anyone have any experience with any of Samsung's other phone offerings? Do you think Samsung will post a radio update for this phone or possibly release one along with the GPS Fix/Froyo update in September?
I work in a position which requires me to be on-call a certain times during the year, and I can't really afford to have a phone that camps out at 60% no signal. I am really looking for reasons to keep this phone, as I like it otherwise, but practically, I need a phone that is going to receive phone calls. Any objective indications anyone can give that Samsung will continue to support this device may help sway my decision to keep it. My 14 days will be up on Thursday, so I need to make a final decision about keeping this phone before then.
Also, do any developers think that modifying the handling of the signal display in Android will cause a change in the amount of time the phone spends acquiring signal between 3G and 2G, or is this something that is purely handled within the radio firmware? If this is changeable, is this something that can be included in a future custom rom?
No coverage issues with mine.matches my mt3g in pretty much every location.
Sent from my SGH-T959 using XDA App
I made a call in the BOONDOCKS of NC, in an old river mill with 22 inch brick walls... NOBODY else was able to place a call other than me (all the big networks and nice phones).
I have pretty crappy 3g service here in new rochelle when at home the phone keeps fluctuating between 0-4 bars for 3G and the data speeds very inconsistent. Sometimes it even falls back to EDGE! This is pretty lame, i called t-mobile about it and they said there nothing they can do! If i am unhappy i should return the phone.
I live in NYC...
That is really all I have to say.
3-5 up speeds
constant 3g connection
The bars on the phone are funky though they look like there are none but you can still make calls. Its just the software is off just like the battery percentage.

If you're at home why aren't you on WiFi?
Seriously it's the most puzzling thing ever. 3G or not, I wouldn't be using it at home. Are you trying to replace your ISP with your phone or something?
You should do a search. Are you aware of the fact that -0dBm is impossible? The bars are off on this phone and the G1 is mediocre overall. It can hold on to a 3G signal for longer because your hand isn't blocking the antenna but the antenna itself is truly mediocre in fringe areas. Move your hand away from the bottom hump on the Vibrant. A lot of questions you're asking.. you're answering yourself.
I am not all too impressed with 3G coverage here at my home, but I mostly blame the network at my location and not necessarily the phone. TMO has spotty coverage near my house....period, and I live less than a mile from the tower. I have a Blackberry 9700 and it has similar issues with 3G. I've called and complained and they give me the usual "you're green on the map...return the phone....blah blah". I was closer to downtown Dallas yesterday and the phone had full bars and never got higher than -80dbm. Speedtest app showed about 3mbps downloads on average. I wouldn't say it was stellar but it's nothing like at home either. Only thing is my phone never automatically drops from 3G to E unless I am making calls. Once again the Blackberry 9700 does the same thing.
However, I am not completely convinced the phone isn't to blame either. I had a week with the new Motorola XT720, aka AWS Motoroi/Milestone that Magenta is/was rumored (who knows?) to get, and if Moto hadn't skimped on the CPU/RAM/screen/app memory of that phone I would have kept it instead of this Vibrant. That phone seemed to get much better 3G signal and HSPA was excellent compared to the Vibrant. I'm lucky if the Vibrant gets HSPA here at all. Overall network performance just seemed faster. It was quite obvious when I powered up the Vibrant the first time that 3G coverage is going to be an issue at my home with this phone.
FWIW my wife has an iPhone 3G which gets great 3G coverage here at the house on ATT. So I borrowed her SIM to test after I unlocked the Vibrant and it didn't make much difference. It did get 3G which I didn't think was technically possible until I saw that this phone has 1900 3G support as well as AWS. I do think the bars and definitely the battery indicators are not accurate whatsoever. I use Battery Indicator Pro and it's definitely obvious Samsung needs a software re-work.
Just because you live within 1 mile of a tower doesn't mean it's 3G or that there isn't something in the way of it's signal and your house.. I live within 1 mile of a tower and it's not 3G. It's supposed to get 3G soon.

Maybe I don't have WiFi in my house?
Maybe I would love to reduce my monthly expenditures by the $60 I throw away to Comcast?
I am well aware of the fact that -0dbm is impossible. This is simply what the phone is displaying. I also agree that the G1's reception is mediocre, but this phone seems worse than the G1. Blocking the antenna with my hand doesn't seem to make much difference on either the Vibrant or the G1.
I asked for objective answers to my questions which basically boil down to the following:
1. Do you think Samsung will provide support for the software on this phone (including the radio) over the long term ie. do you think there will be upgrades in this department?
2. Do you think this is something custom rom developers can address purely via modifying the OS?

You're asking questions that we can't answer. Do we work at Samsung? No. Would stock Android fix this? Maybe.
It seems worse than the G1 because based on your comments the bars are having an affect on what you deem to be "worse". I've had tons of T-Mobile phones including the G1 and the Vibrant is not considerably worse than any. INFACT it will hold on to a 3G signal for longer than most. My CLIQ displayed 3 bars as -105dBm. Accurate? NO.

I know that nobody here is working for Samsung but there are plenty of people here who have developed for Android, and the question I am posing is if this is something that can be addressed in a custom rom.
I think my original post makes it clear that there is obviously a software issue with bar display, but I am wondering if this software issue is also causing the Android OS to force a switch to 2G in an instance where the G1 with a properly functioning display would keep 3G. ie, the phone is switching to 2G early because it thinks it only has -111dbm when it in fact still has -103dbm. I am not clear on whether this functionality is performed within the OS itself or purely within the radio firmware.
My hands are rather large, so holding the G1 basically covers the entire rear of the phone. The antenna is near the top of the phone whereas the antenna on the Vibrant seems to be on the bottom. Though holding both phones in various positions seems to have little effect on the received signal strength so far as I can tell.
The time spent without signal in cell standby I believe to be erroneous. I think it is tallying up that time any time there are zero bars, even if the phone still has a signal. This makes it very difficult to objectively compare the 2 phones. If the OS is in fact driving the switch from 3G to 2G this may explain my poor access in fringe areas as the phone will be constantly flapping between the two. If the functions that drive this behavior are within the AOSP source this could easily be something we can fix in a custom rom even without Samsung's help, even if a radio update would be ideal.

I can wrap my hand around the phone (Vibrant), either top, center or bottom and I do not see any change in either reception, call quality, network throughput or number of bars.

It is perfectly understandable that if he has good reception with a G1, an older phone, he expects at least a similar level or reception with a newer, higher end phone. WiFi would be considered a workaround.
I just received my Vibrant on Monday and it's sadly replacing my amazing Nexus One. I've noticed that the Vibrant antenna is AWFUL. Where I received 4-5 bars on the N1, I'm getting 1-3 bars now and it even goes down to Edge once every few hours.
Like the OP, I've been monitoring the db levels and they're frequently around -95 through -107. While my calls don't actually drop, the quality does get worse. I'm also getting many 3G connection errors when trying to browser or download apps from the Market. It's quite disappointing. The phone is made of plastic as well, so I'd imagine that the antenna reception should be better.
Being that there are only 2 pages on this particular thread, does this mean it's a fluke and others' phones are ok?

Thanks. 3G is spotty at best in the Des Moines Area, so I'll leave well enough alone.
So, in follow up to this, I had downloaded and installed RF signal tracker from the market and went driving around until I found a tower. It seems that via Android OS the best signal strength received was -81dbm and that was sitting right next to the tower. The phone stayed locked at -81dbm for a few miles down the road so I suspect this is peak signal on this phone which should really be something like -65dbm. I think this pretty much confirms that there is indeed a software issue with the signal display.
I also took some time looking at Android code and found that the bars are driven on GSM/UMTS by asu as follows:
if (asu <= 2 || asu == 99) iconLevel = 0;
else if (asu >= 12) iconLevel = 4;
else if (asu >= 8) iconLevel = 3;
else if (asu >= 5) iconLevel = 2;
else iconLevel = 1;
So figuring up the dbm values from these, I went ahead and created a new asu scale which is adjusted -8dbm from "normal" since this seems to be the worst case of the mismatch between the phone firmware and what Android is reporting and applied that within the market app Real Signal to try and get an apples to apples comparison of signal bars between this phone and the old G1. Unfortunately, the degree if miscalibration means we can't set a negative ASU so we don't get any meaningful display on Real Signal until we hit the 3rd bar. In doing this if I go to a moderate overage area I am seeing the bars I would expect.
After my little drive with RF Signal Tracker its actually pretty clear that discrepancy is really more like -15dbm, which adjusting the figures should mean that this phone in reality gets slightly better reception than the old G1.
It seems we should be able to workaround this in a custom ROM by doing one of the following:
1. Modify getGsmSignalStrength() to add the -15dbm to the returned signal strength value(hackish).
2. Modify the vendor RIL to compensate for the -15dbm offset when on UMTS. (Probably the proper solution).
I'm not clear on whether the vendor RIL code gets posted to AOSP...

Also, do any developers think that modifying the handling of the signal display in Android will cause a change in the amount of time the phone spends acquiring signal between 3G and 2G, or is this something that is purely handled within the radio firmware? If this is changeable, is this something that can be included in a future custom rom?

I haven't done any detailed tests but I can state that in real world use, I am not happy with my Vibrant's reception. My G1 was very noticeably better at getting and holding 3G and Edge connections in the same locations where my new Vibrant won't.
Next to a tower on GSM(GSM/GPRS/EDGE) you should see -51dBm at the most with Android. W-CDMA is different because they really don't use -dBm to determine signal quality. They use power/noise.

*Method to IMPROVE Vibrant reception?

Hi everyone, I've had my Vibrant since mid-December and I love it except I get VERY spotty reception in my house.
I know it's not a carrier issue, as my mom and friends have the same carrier (Wind Mobile) and they seem to have decent/good reception at my place. My reception drops consistently in my main floor and is non-existent in my basement.
I'm running TW Bionix V with KA7.
Is anyone aware of a hardware fix (similar to the GPS fix) that might be do-able and works?
Thanks
Have you tried flashing different modems to see if any of them make a difference?
You may also be experiencing bad reception due to the fact that the antenna is located at the bottom of the phone so our hands block it when we hold the phone in portrait orientation. Why Samsung chose to be it there is beyond me.
I know what u r going thrugh, my 2 brothers have vibrants aswell and for some ****ing reason my vibrant has significantly worss signal then their vibrant. I already tryed opening it and puting an external antenna but it only helps if the antenna is going straight ought of the phone, as soon as I try to close the cover it losses its usfulness.
I've tried different modems in the past.
KA7 so far has been the best, but that isn't saying too much.
I have actually just opened up my phone and located the 2 copper connectors at the bottom right (when my phone is turned back-up). I read in the Correct GPS Fix thread (http://forum.xda-developers.com/showthread.php?t=878970) that these are the cell reception connections.
I put a small piece of rubber underneath the connection and SO far it actually seems to have improved it.
I will report back throughout the day. Typically I lose reception while walking through my house so I'll see if that happens as well.
*Sigh*
I think it may have been a placebo effect. The reception is still dropping off on my phone while in the house.
Doesn't seem like bending the copper connection does very much.
I'd just try different modems. For me, KA6 < KA7 < KA5/JL5 and KB1 has been great for download speeds.
You're holding it wrong! Hold it the correct way (at the top).
Just kidding, but yeah, try different modems. KA5 and KB1 gave me the best reception. Or maybe Tmobile has poor coverage in your area.
Why dont you use wifi calling feature at home. Then you shouldnt have a problem unless you dont have internet at home.
I wish I could use wifi calling!
I'm actually in Canada using Wind Mobile (not T-Mobile), and it doesn't work unless you're on the T-Mobile network/using their SIM if I'm not mistaken.
The coverage in my area is decent (my mom and friends get steady reception, while I do not).
It seems to be specifically for my Vibrant.
I will try changing the modem to maybe KA6 (I can just flash with CW?) and see if that fixes anything.
My phone have a hardware defect when i'm holding the phone on it's bottom left.

When you say your mom and her friends have great reception, just curious, are they using Smartphone?
Because if they are using feature phone then the phone might be displaying 2g network strength oppose to 3g which your phone by default tries to get on.

They are on the same network (Wind), my mom is using a Blackberry Pearl 9100 and my friend is using a Moto XT720. Both are set to only use the WCDMA network. So it wouldn't be a problem with them on 2G.
I just find it odd, some people are reporting great reception with the phone, but my reception has been half a$$.

**** I wish I knew what makes my vibrant reception worse then other vibrants. if it is the internal antenna then I might work something out but if it is a defective motherboard then I'll be waisting my time.

No, actually, the other way around. I have BETTER reception with the Otterbox, as weird as it may sound.

I normally just load the modem into the internal sd card, then reboot into recovery and then install by "choose which to install> select it and say YES
That never has problems sometime CWM can hang it it is a hassle.
Also, there is a patch that allows to use wfi calling doesn't matter that carrier doesn't like it it works........

How to increase consistency/strength of the phone signal

My phone - I have ICS - S-OFF Amaze with Energy ROM and I had tried to apply blas0id tweaks.
The problem - In certain areas I don't have phone signal for a few minutes, then suddenly it will show 4 bars for a few minutes. In general the signal seems fickle.
Before ICS upgrade, when I had GB, I always had 4 bars in the same places. I *think* I had good signal with ICS before I did blat0id tweaks, but I am not certain of that. (ICS and the tweaks were within a few days)
My wife's Iphone still has excellent signal in those places. Tmobile Mytouch also has excellent signal in the same places. So something has changed on my amaze and not the cell towers.
What I have done so far -
1. went back to stock ICS by flashing the img file. That did not improve the signal. So then got back to energy
2. Tried another ROM - speedrom. No improvement in signal
3. Tried few apps like fresh network. They did not help
Please help me
What can/should I do? I love my amaze, but if I dont get consistent signal, I will have to replace it
Are there any tweaks that I can try?
How about the custom kernels that have been made for ICS recently, would those help?
Is there a way to increase the power to look for and catch on better signal? I can trade battery life for better signal
Thanks
I have same issue but with WiFi only. I never had GB I hope there is a work around

Found a workaround
This was dumb luck, but when I was trying to play around the app opensignal, it wanted me to set 2G for some of its functionality, since that functionality does not work over 3g. So I went to setup and set Network mode to "GSM Only" from "GSM/WCDMA Auto"
And walla! right after that my signal jumped from 1 bar to 4 bars and has stayed there. I went back to WCDMA and signal dropped, so now I change the network mode only when I need 4G. Its a pain, but at least, the signal is good when I need it.
So with that information, can someone help how I can tweak something to get my 4G and also good signal?
Thanks
try updating the radio if you have done so, even though you are going to have to go through the process of locking the device again and unlocking the bootloader again, that would be an idea to try, we still dont know what changes R2 radio update has done but its deff worth a shot

I checked the version of my software and I think I already have R2
Build number
2.14.531.3_R2 CL373265 release-keys
So not sure if that would change anything
I have always had this problem as well sometimes I have 4 bars of signal then it drops to the X as in no signal,can't make calls or sends texts until it picks up again, happens totally random don't think it has to do anything with tmobile coverage since I live in the center of Miami. Also most of the time I have 2 bars of signal in most places, I believe it's faulty hardware

Krazex .. did you try to set your network mode and see if that helps your signal stick around longer and get better signal? That is working well for me.

yup, that's what this setting is supposed to do, but it increased the quality of my phone signal, that is what I am trying to make better/consistent. Because even after all the bells and whistles, calling someone/receiving the calls is the primary purpose of the phone for me and if that doesn't work, the phone doesn't work for me
GSM = 2G
WCDMA = 3G/4G
Get a new SIM card.
My amaze won't get 4g in my house whatsoever, only switches to 2g when it feels like it.

A new sim card is a good idea.. so is removing the back cover and cleaning off the contacts with a q-tip and some rubbing alcohol. Taking something and SLIGHTLY bending out each of the gold contacts so they make better contact with the case, making sure there is no debris.
Another thing to look into- there is a TON of hacks for cellphone signal that can be done in build.prop.. playing with those settings is probably a good idea.
The last idea- the signal is actually NOT different. The number of bars it shows you is now just more ACCURATE. You still lose signal in ONLY the exact places you would have before.. but now when your phone would show you as having 1 or 2 bars(on gingerbread) right before you lose all signal, on ICS it shows you as having NO bars because you truly have almost lost the signal. It is VERY accurate, now that I am in an area with bad signal.. I have actually flashed gingerbread again and things did NOT get better, there was just fewer bars that weren't as accurate. But I lost signal in the same spots, and would lost 4g in the same exact spots..

Guys, OP here. This question/workaround is not about getting 4G. I am getting 4G just fine. Its about the phone signal (the bars). My amaze does not get good phone signal in some areas and when I set the network mode to GSM only (2G), phone signal strength and stability increases. and now I want to figure out how I can keep the setting to 4G and get a good phone signal

Hi SBD, thanks for coming in. I will look into build.prop (ro.ril properties I think) I will also clean any dust inside the phone, may be that will help. The sim card was new when I got my amaze .. but no harm in trying. So I will ask for a new sim card too.
However, in my case, I have a different experience. This is what I did in a weak signal spot.
Have 4G on. I get 0 signal. Can't make a call
go to 2G at the same spot, I get 2-3 bars. I can make a call
I used opensignal app to check signal strength in both cases. with 4G it showed 0. With 2G it showed 42%
Another test. On my route to drop kids off for their day camp, I was on a call (with 4G on) and dropped the call twice (bad reception areas) while going. I switched it to 2G and while coming back did not drop the call.
Before I found this workaround .. people called me and complained that it directly went to voicemail and I never got the call. (no signal). Since I found the workaround, I haven't heard that from anyone.
So I am convinced that there are some real issues in catching the signal with 4G on that get resolved in "2G only" mode. (may be it has to do with the kind of cell towers we have in our area and nothing to do with the phone)
will update if I find more

Yea, it should be lines that have ro.ril that youd eant to change.. and fortunately one of those that you can add(it isn't included by default) will do exactly what you need, default to 2g signal when 4g is too weak. I actually need the same thing, in Jacksonville we have great signal.. except in this new place I moved into. It drains my battery by trying to stay with 4g.. but I don't have time before work to find it.
Look for a tthread by "master&slave" titled something like "super build.prop tweaks" in the vibrant forums, I THINK they had that line.. otherwise google around for something like "build.prop signal tweak" as if it isisn't in that thread, there's a really good one on some other forum.
Also, I remember there being some app that requires root that allows you to toggle between GSM preferred and 2g only.. it changes it at system level, and I don't think it was on the play store, I think it was on Xda.
But yea, I understand your dilemma, and until we get an alternative radio to flash(which I don't forsee), that is the kind of workarounds you need. If you find a reasonable solution make sure to post as it will help me too!

I have had this problem ever since I got my phone in October (right after launch). Updating to ICS didn't help. i've been planning to root and try another ROM, but so far have been skittish as this is my only phone. hasoon, you say it's the SIM card? I am trying the switch to GSM only to see if it makes a difference. My problem is at home - I have terrible service and I live on a mountain with cell phone towers everywhere. My daughter's AT&T and my old AT&T Nokia E71x had excellent service there. I'll let you know if this helps. Maybe a trip to my local t-Mobile store is in order.
It's not the sim card. I noticed on google a lot of people have this problem with htc phones. It's just a bad radio.
