[Q] Poor signal GSM/WCDMA auto - HTC Sensation

Im looking for some help to try and resolve the poor signal i have on my handset.
The problem is, at home-
-if im on GSM only (settings-Mobile networks-network mode) i have no 4-5(FULL) bars signal no problem.
-If i am on WCDMA i have no signal-1 bar.
-if i am on GSM/WCDMA auto i also have no signal-1 bar.
So what i am asking is- does anyone know how or where to alter the threshold for when the phone switches from GSM to WCDMA when in a low WCDMA signal area. I think the threshold is set more towards WCDMA and i would like to at least fiddle with the values to make it more usable.
I could just leave the phone on GSM but i lose out on high data speeds if i am in a good signal area.
Also for reference i am in the UK on O2. I previously had a desire and never had signal issues. I have also tried a new back cover on my phone to check that the anteneas were working- and it was the same with the other cover (genuine HTC not from fleabay).
I have also tried a few different roms, Different radio's & matching rils and i still have poor signal so this is my last idea really.
Any and all help with this issue is much appreciated.
Thanks

i dont have any case on!
I have since discovered, i went into the phone config secret menu (*#*#4636#*#*) and the network selection was WCDMA prefered. When i compared this to my girlfriends samsung galaxy W (stock) her's was set to GSM/CDMA (PRL) so i swaped mine to match her's and it has helped a bit but the setting seems to revert back to WCDMA prefered when i reboot.
Does anyone know where or how to set this permanently? Built.prop or something?
Thanks

I struggled with signal I bought a case mate protective cover for the back, and from time to time I stretch the pins under the battery cover, my signal is pretty strong normally get 3-5mb down speed aswell, wcdma preferred is the right option IMO, have you tried your sim in another phone? Sometimes sims need replacing

# Default network type.
# 0 => WCDMA preferred.
ro.telephony.default_network=0
Can anyone tell me why, if i change this value using es file explorer to
ro.telephony.default_network=3
it is still WCDMA prefered after a reboot. i even tried wiping cache and dalvik?

Might be an issue with the radio. If you are on a custom ROM, make sure you flash the recommended radio.

I just got an otterbox box case and my signal got better ...

Same problem
This dude(beady) has literally given detailed description of the problem im facing aswell..
-good network in GSM mode(only edge no HSDPA)
-very poor network in WCDMA mode(HSDPA) with a lot of drop calls ...
im not rooted..In India Dehradun on Vodafone with Samsung Galaxy S3(pebble blue)
is it a hardware problem??..software problem??
please help..i need good data speeds with a good network to take calls aswell(what phones were originally meant for ..)
what to do..nobody still seems to have given substantial answer.

Have you tried the generic ICS radio/ril? I know you tried different radios but have you tried those?If you want you can change radio /ril and find one that provides a better signal. Radio /ril is something that you really have to find out for yourself as to which one is best because we all live in different areas and our signals will be different. Best place to start would be generic ICS radio and ril . They have several different ones available. It will take some experimenting on your part to see which radio and ril files will provide the best signals for your area. This is a option. I've done this myself. I was lucky, the first radio and ril files I flashed Madre a great difference for me. But start out looking in the generic ICS radio / ril files.you should have success there. Remember to flash BOTH radio AND ril. The ril is flashed the regular way , the radio is flashed like pg58img file through bootloader. Also remember to DELETE the pg58img file after it updates or it will continue to try to update over and over. Hope this helps! Best wishes!

Try this, on dialer type in '*#*#4636#*#*' without the quotes.
Click Phone Settings.
Select 'GSM Auto(PRL)' under the list to choose from.
Don't touch anything else.
No reboot required. A reboot restores what you've done. So, if you have more problems then reboot.

bad signal related to the radio version?

So I decided to Root, S-Off and flash Coredroid v4.7 on my Inspire, but I leave it with the stock radio (12.39.60.19P_26.06.04.06_M), but the signal seems pretty weak even on places where my Nexus one was at full strength my Inspire seems to only be able to grab 2 bars at much, and the WiFI connection seems week too, on my N1 I used to be able to get full signal from more than 20 meters, but my Inspire seems to lose it after 15 meters.
I read some posts and other blogs/forums and some attribute those issues to the radio version, so I hope someone can give me an opinion and tell me if I should Update the radio and to which version if so.
Thanks in advance.
Try this
For phone signal, try *#*#4636#*#* in the dialer. This will bring up a screen that has 5 options, I went to phone and scroll to the bottom. Under the preferred network I changed it to GSM only as its an AT&T phone anyway, I was getting 1 or 2 bars at home and was missing calls left and right. after setting this, back out and shut the phone down then restart. I have all 4 bars now. It would also eat the battery, mine was on WCDMA preferred and I think it was searching for that signal constantly. There is a screen for wifi also but there is nothing adjustable there.

Odd that it would have WCDMA preferred as default. I just adjusted this as well and it improved the signal in my office. Good catch.
Gsm only does not work for me, my lame carrier runs on gsm but their mobile internet runs on their 3g so I need to connect to both. Setting it to wcdma/gsm auto seems to have improved the signal

Hey all, I'm on AT&T running radio 26.06.04.06_M. Any specific recommendations? GSM/CDMA Auto (PRL) seems to give me the best service based on bars, but that doesn't necessarily mean much (I'm on an HSDPA connection with 3/4 fluctuating right now).
Also, I think I might not have HSUPA enabled with this radio, I'm only getting .56Mbps upload and around a 2.79 download (Whereas on standard 3G with my old iPhone I typically pulled around a 1.2). HSDPA is without a doubt enabled and it shows that I'm connected on that network, but is there a better radio I should try out?

[SOLVED] 3G data connection hiccups.

Hi there,
I'm using Revolution HD 3.6.1 with its radio and relative RIL (which becomes with the rom by default). Obviously I have S-OFFed and rooted.
I'm experiencing some hiccups in 3G data connections. I don't know if it's due to the carrier (Wind Italia) or something in the phone (maybe the radio doesn't support it at all?). I'm in Europe, precisely in Italy.
Maybe should use an european version of radio? Or what?
In detail:
I activate data connection. The phone shows 3G before, and quickly goes in H (HDSPA). Then I use many apps that needs internet connection. Within a short time it goes again in 3G and i have absolutely NO data connections. After a delay of 5-10 sec it goes again in HDSPA and everything works. When it goes again in 3G i have no data, then again H and data working.
What's the problem?
EDIT: Problem solved! See in this post.
P.s.: Sorry for my bad english
I was going to ask about something similar to this, so rather than start a thread I will post it here. I too am running the 3.6.1 with its radio, S-OFF, & rooted.
What I am seeing on boot up is the standard progressive upgrades of data networks (just bars, then 2G, then 3G, finally H). The H only stays for a few seconds then drops to 3G and basically stays like that. However, as soon as I open an internet requiring application, it jumps to show H and typically stays that way as long as a data connection is active. My Speed Test results show its 4G speeds (same as stock ROM and radio) when its showing the H, so obviously its working, I'm just wondering if its intentional that the display only shows 3G? Or maybe its set so the ROM "relaxes" on 3G, but switches to 4G when data is actually being sent/received?
~T.J.
Maybe you used to have a 'background' app updating constantly.
The G, 3G and H usually depends on the signal in your area, the H is usually for high data transfer. If you're not using the internet,downloading anything or updating anything on your phone, then why would you need it on all the time?
3g is usually the norm, so I wouldn't worry!
For my issue, my stock ROM showed me what was available in the areas as I moved around, including showing 4G all the time if I was in a coverage area (which pretty much everywhere around me is). If I moved out of the 4G area for instance, it would drop to show me 3G.
This one just shows 3G all the time, even when I'm in areas I KNOW are 4G; UNTIL I use the data connection, then it switches and shows the H. I know its silly, but I liked actually gauging my providers service by being able to see what kinds of connections were available in various areas.
The fact I have to actually open the browser or run a speed test to see if 4G (H in this case) is available in that area is a little odd to me, why doesn't it just show the connection that's available?
~T.J.
Guys, I found a solution to my problem, googling around. That's awesome.
FYI I'll post here:
1. dial *#*#4636#*#*
2. Go to phone information
3. Toggle ciphering so it's off
4. Turn off radio
5. Turn on radio
6. Toggle ciphering back on
It seems to be working to me. An half hour without hiccups till now.
I have had this problem ever since my hd2 two years ago. I thought it was normal. I'm about to try the fix. If it fixes it you are a life saver.

Aww man same thing. Maybe its supposed to be like this.
Basically for me its for example on the xda app when ill refresh something it will always say processing as soon as the 3g symbol turns to h with both arrows on simutaneously.
Maybe that's how its supposed to be idk.

Dropped Connection to Network Problem

my phone will drop connection and then not reconnect. no voice, no data. (wifi still works)
what I've tried:
1. Different radios/firmware
2. different roms
3. different preferred network types
4. switching airplane mode on and off
what I haven't tried:
1. different sim
2. calling tmobile for suggestions
What else could cause this problem?
it could be a hardware issue
Hello,
I have the same issue than you !
I am facing issues such as call drop and no 3G data connection in some area in my region since I have 5 signal bar and H letter displayed (HSDPA connection)...
I have found a workaround consisting in:
1 - Switching to GSM Only mode (2G Only)
2 - Desabling Mobile Data Connection
Then it works, I can pass and receive voice call ...
Regards,
Nino
I'm new to the Sensation and having the exact same issue.
Followed the stickies in the Dev section to S-OFF, root and bypass SIM lock and then once the SIM card is inserted I get only GSM and no data.
If you use *#*#4636#*#* in the Dialer and go to Phone Information do you notice that it always switches to WCDMA preferred? I change to GSM/CDMA auto PRL like all my other Android devices (on Rogers Wireless) and it disconnects, reconnects but only for GSM and no data. It sometimes says it's connected to EDGE or HSPA but no icon at the top right and then it reverts back to GSM.
I have also tried flashing virtually every firmware, ensuring that the radio and RILs match (I had an HTC Desire Z so the HTC phones are not new to me entirely). I don't know what else to do. I tried a Bell SIM card and tried all of the same options to no avail.
I really hope someone can figure this out. I don't want to have destroyed a phone that I just bought for my wife. Her Atrix broke and I purchased that outright as well, so this is really killing my wallet. I've been through about 10 Android devices and I wouldn't say I'm a newb, but I really do feel like one right now. This sucks!
Get a new sim from tmo if it's over 2 phones old.

T-mobile HTC sensation signal problems

I need help, I'm already desperate...
Got a T-mobile HTC sensation, it was already unlocked for other carriers but no S-off or unlocked bootloader.
I got an S-off, unlocked the bootloader, changed CID, flashed Android Revolution HD 6.7.2, but I have HORRIBLE signal reception. So I found that update file in the header which said "- HTC Sensation 4G (U.S. T-Mobile PG5810000 | T-MOB010) users can flash this for better signal and data speeds!" I installed it... NO IMPROVEMENT, my last hope is flash a different radio. Anybody knows what's the problem and how to fix it?
configs right now
different carrier sim (not t-mobile)
S-off, unlocked loader
HBOOT: 1.27.11111
Radio: Radio_11.76A.3504.00P_11.24A.3504.31_M
cid changed to 1111111
firmware: 3.33
ROM right now: is the XE version with beats (tried 1.2.2 too, no change)
Kernel: faux
EDIT: just found out that my wifi is not working either, tried the boot.img fix, didn't help. I get Wifi for a brief second and if I managed to connect it will stay for a while, but if I don't no wifi after that.

Greetings. I'm taking a stab at asking my question here because it seems sort of related.
I'm a T-mobile USA customer with a brand new SIM card in my Sensation 4g that I bought a few months ago.
My bootloader is unlocked, I'm S-off, I've flashed the custom firmware (version: 3.32.401.3) that was recommended for those flashing the Cyanogenmod 9 ROM. I'm currently using the most recent STABLE Cyanogenmod 9 ROM (not 9.1, but the STABLE 9 ROM). I'm using the stock Cyanogenmod 9 kernel (the one that came with the ROM: 3.0.26-g7290c7f). I never bothered to flash a new radio, not sure if that's a mistake or not.
My reception is good but it seems rather obvious that my phone is completely unable to hook up to or unaware of the 4g network. When downloading, the icon in the taskbar always shows either "3g" or "H" and when I check the "Status" in "About Phone" my "Mobile Network Type" is always listed as UMTS:3 or HSDPA:9.
Can anyone make any suggestions for how I might begin the trouble shooting process to remedy this issue. Thank you in advance for any sage like advice you might provide, I'm pretty lost here.

H is good. It means you are on an HSDPA network. That's 4G for the purposes of this conversation (though what really constitutes 4G is a little more involved)
HSDPA:9 might just be the best speeds that are available in your area. For instance 8 is the best I can get at my house. No amount of better phones will fix that. It's just what's available from the tower.

That's helpful thank you. One last question in the interest of clarification. Should I find myself in an HSPA+ reception area, should I expect the information over the reception bars to change from 3g to 4g and would "Mobile Network Type" then reflect HSPA+ as opposed to HSDPA 9?
Just curious so I might know what to look for when crossing into better network areas.
Thanks again for the tip.
The H means 4g technically. You can update your radio and ril very easily. Will find links and edit post

Thanks for the link. I guess what I was wondering is whether or not I actually need to update my radio, I'd feel a lot more confident in my reception if I ever saw HSPA+ listed in my phone's "Mobile Network Type", but I never do. I had previously thought that HSDPA was 3G, but maybe I'm missing something.
Thanks for the link, flashing a new radio is something I had been giving consideration, I'm just wondering how user friendly the process is. Like picking a needle out of a haystack, or is there someway to narrow down what radio/ril combo is best for one's phone/network.
I'll read through the thread for the link you posted and update my progress here later. Thanks for the info.

your data connection will still say 3G, unless you start to use the data then it will automatically switch to 4G/H (saves battery this way)
HTC made a fault with the Sensation with building the antennas into the back case (hand over the back of the phone = small loss of reception)
Theres a program called getRIL in the play store. You can update your radio and ril as long as your root. Which i assume u are. I do it thep old fasion way though.

Mhhmmmm .... may be a baseband/hardware problem...
For example, I live in Colombia (south America) and I've a HTC Sensation 4G (T-Mobile) and my signal is 2G/EDGE always, because the HSPA/3G band in this phone is not supported in my country
Isn't supported, why? I don't know... What I know is this problem is a hardware issue (search in another threads) and for the moment there aren't solution.

MAYBE the 3G frequencies of your phone isn't supported in your zone/area

Hi,
Try this:
Take off the back cover.
At the bottom of the phone there are 2 gold pins.
These are your phone radio connectors.
Lift them GENTLY up,so that they make a better connection to the back cover.

Sometimes WCDMA Preferred is a good setting. Then it'll try for 4g and default to lower speeds if the network isnt available

Hi,
Try this:
Take off the back cover.
At the bottom of the phone there are 2 gold pins.
These are your phone radio connectors.
Lift them GENTLY up,so that they make a better connection to the back cover.

Have you tried selecting gsm/wcdma auto in the network menu? You haven't made it clear whether you've tried this. Your settings may be stuck on gsm only.
