WCDMA signal horrible

I've flashed my phone countless of times now over the past months and one thing I was hoping for would be better signal strenght for WCDMA mode... I live in Switzerland and my provider is sunrise. Whenever I'm using WCDMA mode the signal is just horrible. Mostly 1 bar or sometimes dropping to zero. 3g and H works most of the time, but the signal is bothering me.. I've tried different modems etc.. but nothing seems to change.. Does anyone else have this problem?? what can I do about it? GSM has full bars most of the time and that's why it's so weird.
also worthy to note is that people hear an echo sometimes when they're talking to me both in GSM and WCDMA mode.

it would be great if someone knows how to solve this problem...

have you been on your providers website to check the coverage in your area ? they could be a fault on their part affecting your signal strength
Im on Vodafone UK and i have terrible 3g signal, I can only use 2g/GSM otherwise my phone doesnt recieve 1 bar of signal - bit of a bummer when you have a smart phone and unlimited internet
Finally, How was your signal before you flashed ? when the phone popped out of the box ? was it still poor then ?

Telus + Verizon Milestone 3

Hey everyone just a few questions.
*Fixed the 3g network , wondering if I can get 4g working ?
I have a Motorola Droid/Milestone 3 that is unlocked and I can use my Telus sim and make calls, and text and so on when set to GSM mode. The signal is a bit weak however. Is there anyway to increase the signal ? My local telus phone received 4 bars here and I only receive 1-2 if im LUCKY with the Droid 3 . Is there anyway to increase the signal, it's on GSM mode right now but when I switch to CDMA it gets a high signal but I hear the verizon woman talk.
Phone : Motorola Droid 3 / Verizon / Unlocked
Carrier : Canada / Telus Network
Data : I have a Data Plan
Thanks in advance ! If I need to provide anymore details just let me know!

As far as the signal strength thing goes, you could try what is listed in the second post in the following thread. http://forum.xda-developers.com/showthread.php?t=1406812 . I think the issue isn't actually the signal strength, just that the indicator is showing it incorrectly, but I might be wrong. You must have a rooted phone to be able to edit the build.prop file.
I don't think the XT862 actually supports what is considered GSM 4G (14.4Mbps), it only does 7.2 Mbps, unlike the XT860 which does the higher.
*EDIT: Apparently it is capable of at least 10.2 Mbps download, but it just may not show a 4G notification icon. You should run a speed test on it next to a 4G phone there and see what it gives you.
Hopefully that will help you out.

The signal indicator should show H+ or 3g depending on the rom

[Q] Poor signal (one bar)

hello, I have a new t mobile htc one I got as gift (never opened). My old phone was an unlocked samsung galaxy nexus using a tmobile prepaid sim. I resized this sim to fit the htc one and everything worked fine( full bars for signal). Problem with this sim is that I could not make wifi calls. So I called tmobile and had them activate the new sim which I got with the htc one (Same prepaid plan, no data). i can now make wifi calls. Problem is once wifi is disconnected I only have 1 bar. If I attempt to make a call all bars raise in full, even if i attempt to check my balance the bars automatically jump from 1 to full and back to 1 bar after i see my balance. Is there a setting i need to change or is this normal? i am worried I may be missing calls like this. (All this happens when the wifi is disabled)
Sorry if the post is confusing, I tried to provide all the details but will be happy to provide anything else if necessary.
Thanks!

This happens with me sometimes as well...if it is in LTE mode, the signal bars are less...1 , sometime 2, and sometimes 4... as soon as i make call, the data connection is OFF for that moment, and the signal bars are full....as soon as the calls end, the data connection is activated.... the bars are less again.... try changing the data connection modes from LTE to 3G only and to 2G....and see what happens

Awesome this helps. Thanks. In my situation I have no data plan setup. No need for any internet on my phone atm. So all I use this phone for is calls and an occasional sms. Will I have a longer battery life if i disable lte and have it on gsm only? Would the call signal drop?

i am not sure, but when you dont use Mobile Data on your HTC one, there is no need to select the LTE mode.... you can select the other option always. and it might save battery as well....."might"

You will definitely save on battery if you switch to 2g if you don't use data at all. Switching to 3g frequency takes more battery even when there's no data connection.

I switched it to gsm only then disabled mobile data. Full bars now. This should work. The next option is wcdma which i dont think tmobile uses.

[Q] Incoming calls is lost, bad reception?

Hi,
I have a Samsung S3 LTE (I9305) for Europe use. After last repair(swtiched middle parts near mic port) I have hade friends telling me that thay have called me but the phone never registered any calls? Its not often I hear it but from time to time. Apart from this the phone if working great, never problems to call or during calls.
I have switched the microsim card and I set the phone to use 3G because 4G is not that great here. It always have full bars with 3G and in the status menu it says -69 to -73 dBm 20 asu HSPA(network). If I switch to 4G I will get 1 bar and it says -102 to 105 dBm 34-37 asu LTE
If I send it on service and thay dont find any problems, I will have to pay for the shipping and troubleshooting.
Could there be something wrong with the phone?

Cell signal keeps reverting to 3G

Hi,
So I'm having an issue keeping an LTE signal. I use straight talk with at&t and I can get LTE if I turn the radio on/off, but it will always switch itself over to 3G at some point in the same location. There are apps that can force it to do LTE only which works, but I can't make or receive voice calls over LTE.
Does anyone know how to fix this? This never happened on other phones on the same network. In my specific location I get 2-3 bars of LTE and 4 bars if switched to 3G. I guess it wants to keep using the better signal.

Also at home where I have full signal LTE and H+, it will choose H+ over LTE.

Had same problem. Switched sim slot to the other. 4g again. Try IT?

Did you try different APN settings? I'm guessing you already checked the preferred network option.

APN settings are good and I can get LTE if I flip the radio on and off...it just always wants to revert back to 3G at some point. Same thing happens in sim card slot 1 or 2

Which rom are you on? I remember there's a specific rom that has a bad modem file. Trying updating to the latest version.

Maybe you can solve it by going to APN settings and set APN protocol -> IPv4 and APN roaming protocol -> IPv4 . That worked for me. I had the same issue.
Or try IPv4/IPv6. That's network related and maybe IPv4/IPv6 is correct for you.
I have to set it every time I flash EU or EPIC rom.
Good luck.

did you ever figure this out?
I'm having a similar problem on a Note 4 Global. Only it switches to 3G for a voice call and never switches back.

Firmware update?

I've updated it, and it's all the same. Once in a great while it will switch over to LTE on its own, but 99% of the time it will just sit on H+ forever even though I know the LTE is fine wherever I go.
I guess this is just how it's going to be.

I finally fixed this by wiping everything in twrp and flashing a newer version of the global stable rom. LTE works fine now, and it doesn't stick on H+ when I make a call anymore.

That's interesting. I guess Xiaomi fixed the bug in one of the releases. I wonder why you had to wipe everything though. What if we try to flash the latest modem. Is there a link to that? Would that work?

Would modem be the same as firmware? There's a thread on here that has those. None of them did anything for me.
My LTE problem is isn't fixed after all I guess. Once it loses LTE, it still never reconnects to it on its own and goes to H/H+ forever.
I guess the only thing that I've fixed is that it actually switches back to LTE after a phone call.
