[Q] HTC Desire's 3G signal is much weaker than 2G

HTC Desire's 3G signal is much weaker than 2G.
I am at home, HTC Desire only has 1 to 2 levels of 3G signal, but full signal when turn to 2G. I use same SIM card on my Samsung i8000, 4-5 levels (5 is full) when in 3G.
How to fix the 3G weak signal of HTC Desire?

Are you rooted? If so, try flashing a different radio version as this can improve 3G speed and signal strength as well as Wi-Fi performance, and battery life.

have tried different versions of radio, no luck. which version of Radio is the best ?

2G has a greater range than 3g, I think.
When I'm in the middle of nowhere I always get a 2G signal even if I know there is a 3g tower closer than the 2G one I'm connected to.
I generally get better signal with 2G most of the time.

sorry,
phones perform differently, also some phones give you a misleading scale on the signal level, there is no industry standard as to what signal level 4 bars is afaik. manufacturers have been known to fudge scales of all sorts on their devices to make it appear better than a rival product.
try to get both phones to report signal level in dBm to compare accurately.
I also get relatively poor 3g signal with my desire compared to some other phones i have had...looking at bars, have never compare dBm.

Bars are no way to tell how strong the signal really is, since i flashed the latest radio i have a decent 3g connection without any bars.
If you already tried different radios there is no way to fix it, different devices will preform differently under the same conditions, nothing to do about that.

this is what I am using. no good.
By the way, to all.
What I mean 3G signal is for voice. the reception is poor for phone call in 3G, it sucks when doing phone calls, but no problem in 2G. I place my SIM card into Samsung i8000, reception is strong and phone call has no suck at all.

[Q] Low signal vs other phones

Hey guys had a question for ya, since I'm new to Big Red I'm not sure if this is something normal or what. I have 2 iPhone 4's and 2 Incredible....I get full bars on my I phone's but only 1-2 on my Incredible. Normal behavior for Android?

It may just be the way they are programed to show bars. You shouldnt measure by bars but by dbm. Both phones could be at -89dbm but one os could be programed to show -89dbm as 2 bars and the other os as 3 bars. To see the dbm's on the inc go to Menu - Settings - About Phone - Network. On an IPhone im not sure where it shows dbm, but im sure its there somewhere. FYI the lower the dbm number the better the signal (89 is better than 99).
Could also be that the IPhones radio antenna can pull a stronger signal than the inc, seeing as it is newer it may be a better hardware thing.

Two bars is showing -72. Guess its just the way its showing the bars
My iPhone is showing the same in field test mode

Yeah there's no standard for what signal strength should be what amount of bars, so some companies have different values. HTC phones tend to have low bars with good signal. Sometimes I'll get 0 bars but I can perfectly watch netflix or talk on the phone with 0 breakups.

Samsung S3 sprint Signal Problem Anyone has issue ?

Hi i just came form S2 to S3 and my signal is real bad
i use to get 4 bars in my house now i get 2 bars at work i use to get 3 bars now i get 1 bar with S3
I have Blazer rom rooted LG8 modem ?
i still have the s2 and i get 5 bars with S2 and i get 3 bars with S3
Can someone advise me or help me how to get a better signal cause this is killing me
Thanks

My signal is better/stronger with the GS3 than the GS2 was. Maybe it's just capacity grew when the S3 came out and made your area more congested?

thanks but i have my S2 and it pulls 5 bars easy good signal
S3 is half of what S2 is pulling don't know what to think ?? I hope there is no defect in MODEM or ANTENNA in S3

Signal bars on custom ROMs are meaningless. I've only got one bar and I'm still pulling in 1.2 Mb per second. In other words there just as strong as the s2 just not display properly.

Look in settings > About Phone > Status and tell me if the -dBm signal strength is the same on both devices. The lower it is, the better connection to the tower. Both phones may be programmed to display different bars when it reaches a certain dBm level.

The higher it is (closer to 0), the better.

Really. I question this because my s2 never did this good and if you remember was plagued with los as well as just plain bad radio, GPS was mediocre,and Wi-Fi was bad. Honestly a barn door or a flip phone do better for reception. Hell even after the los got fixed it was typical to see 3%t. W. S.

-75 is decent connection. Its what I get which is half bars for me
Sent from a Galaxy SIII presented by Sprint.

Thanks all i think signal strength is the same now but S3 is not showing the bars correctly
2 bars on S3 is the same as 4 bars ob S2 cause my download and upload speed are very close.
SO conclusion is signal strength on S3 is not showing the correct reception bars highlighted.
OH well thanks for all your help

There is no such thing as "correctly" displaying bars. Bars are undefined. They just show whatever the OEM marketers and designers want them to show. We might as well call them unicorns. It is never valid to compare "bars" across different devices, or sometimes even across different firmware on the same device. About all you can be reasonably sure of is that on any given device with a given firmware, more "bars" should represent a stronger signal than fewer "bars."
The dBm signal strength readings are standard units and useful insofar as you understand what they are measuring.
Be aware that on the current GS3, both the bars and the dBm display for RSSI under Settings -> About device -> Status are based on the received signal strength (RSSI) for the 1x CDMA voice/text connection, not the data connection, although that should be similar. And if you ever want to measure signal strength for an LTE data connection, the only place to find that is in hidden DEBUG menus.

Try a different modem. I found the LG8 modem to not be very good.

Unless you ever want to get a decent LTE connection, for which LG8 is basically a requirement.

Most of us dont have LTE yet. I didnt see the OP note that he was in an LTE area.
LTE is supposed to be coming here. I hate to flash back to that sorry modem but I guess I should.

"

Forget the bars. The above means that your GS2 is indeed getting better signal than the GS3.
As others have suggested, try different radios (there are currently 4 to choose from). I tried earlier versions, but my phone works best with LG8.

[Q] [Request] Signal bar hack.

Does anyone know how to have the bar indicator read HSPA even when I'm connected to LTE? To me, when I'm connected to LTE I could care less about signal strength because speed is all that matters. I prefer to know how my call would be, so I'd like the bars to read my HSPA signal and forget about the LTE strength. I like to know I'm connected to LTE but like i said, i could care less about what the LTE strength is. If anyone knows how or could point me in the right direction, that would be awesome if its possible. I've looked all over the place and couldn't find it, all the threads I've found tell you how to change the icons and such, which I've done. But this is something I do not know. Any help would be appreciated. Thanks!

Signal bars don't have anything to do with LTE. Unless I completely misread what you said.

Reading this as you have written it, it sounds like you want to read the other car's spedometer on your dashboard and don't care what speed YOU are going at... (not very much of a useful report)............
It makes no sense and is most likely impossible due to the fact that the "strength" is read according to the frequency the radio is working.
Also, "Strength" is not the correct description of the signal bars shown, as it is a COMBINATION of available bandwidth as well as signal strength properties. You could be having a GOOD signal, but there are too many users in your cell service area so the bars are less of a quantity, but you still have service. It's too bad they didn't have a better way of showing that condition.....
Anyways, good luck and Aloha!

I appreciate the response. The thing is, the bars haven't been consistent with speed. At one bar where I work, I pull down 15 Megs, when I go to lunch at the Mcdonalds I have 5 bars of LTE and pull 15 megs. Bars on HSPA also factor in Call quality where as LTE doesn't because you can't make calls on it. The phone has to stay connected to HSPA because of this, I basically want to be able to see my call strength before Make a call. I've read in certain phones especially on Verizon and other carriers especially, they manipulate the signal this way to make it look better. That's what I'm after in a nutshell.

Just change the data settings so that the phone only goes up to HSPA connections. Basically turn off LTE entirely.
That will always show HSPA strength in the status bar because it will always be connected at HSPA signal strength.

He wants lte. But does not care how strong the lte signal is. He only cares about being able to see the hsdpa connection strength.
With that said, if you have lte, you more than likely have full connection to hsdpa. I've forced hsdpa while in a one bar lte zone and hsdpa read full bars. So if your data connection says lte, 99.9 percent of the time you will have full hsdpa connection.

If he wan'ts that then he can't have it. The radio can only connect to one signal type at a time. And the only way to know what the HSPA signal strength is would be to be connected to it so it can be monitored. So in any situation where it's possible to determine the HSPA signal strength, you can't be connected to LTE.
Unless you carry another phone around that's always connected to HSPA and use that as a refference, but that seems....dumb.

I was just wondering if it was possible My question becomes, if it can only be connected to LTE and not both, how do I receive incoming calls cuz I know that they don't do calls over LTE yet cuz they haven't launched VOLTE. Unless you were a lucky Mtetro PCS Customer. Not trying to be a pain in the ass, legitimately curious.

Your connection switches to hsdpa. If you set your connection to "lte only" calls will not work. So it switches before connecting. And about VOLTE, will we need a new phone for that to work or is it basically a T-Mobile side thing?

[HELP] Still having signal issues

I'm on virgin 3.1.2 and I'm still habit the same issues. When I turn my screen back on after letting the phone sit for an hour I start getting every notification that should have came in when the screen was off. My phone says im on mk2 modem but I still only have 2 bars of lte like like I had on MDL. Also my bootloader says write protection enabled, is this stopping me from. Getting my modem flashed correctly?

Flashing of MDL wont magically make your signal better. Might help with consistency and other things, but it won't make your bars go up. With the new TW update on 4.4.2 samsung has manipulated the signal to make it look better, but you're not actually getting a better LTE signal, it's just telling you the bars of your HSPA signal to make it look better. As far as the MK2 vs MDL modem, it wont make your LTE signal boost either, it will just make your signal not drop so often. Signal has more to do with the tower distance and type of frequency its using than software on the phone. Hope this clears a couple things up for ya.

I get good speeds, just always only shows 2 bars. Sometimes I will watch it go from lte to 4g then 3g then the signals dissappear and I lose all signal for a few seconds. Then it comes back to lte.
Not worried about it now , tmobile sent me a replacement phone and even on stock it has the same signal.

I don't think its showing the hspa signal, I've had 3 hspa phones in about as many years and the number of bars showing is not the same like my other phones.. I'm not saying they didn't manipulate it because I tested it and compared dBm signal strength when i first updated to KK and its the same as I've always gotten, it just reports higher bars, my s3 shows 3 bars, my s4 5 bars, both on hspa and same exact dBm signal

Depends on which HSPA signal it's reading. Sammy may have programmed it to read the 1900 signal rather than the 1700 signal which will report higher signal strength. I've compared the bars of one of the phones in the local store here in town, and the bars of the hspa coresponded with the dbm on the other phone when I forced it into wcdma only mode.
