[Q] Connectivity problems due to WCDMA vs. GSM - HTC Sensation

I just got an HTC Sensation and am having terrible connectivity issues. I've narrowed it down to this:
When I leave my network on GSM only, I have decent reception but can only use EDGE and lose my MMS sending and receiving capabilites (which I use often).
When I switch to WCDMA only, I have no reception whatsoever.
When I switch to WCDMA/GSM auto, I have really bad connectivity (constant dropped calls) but I'm able to send and receive MMS.
My sim is a brand new 4g sim from T-Mobile.
Anybody have any idea how to fix this? I checked the forum but didn't come across anything.

I assume you are on the stock ROM and are unrooted? Are you using GB or ICS update?
I also had this problem on GB stock ROM, and partially fixed it by using cell tower predefined lists, rather than using the auto option which made the phone constantly search for the tower with the highest reception, something which my Sensation failed to do properly.
Try this method to begin with, it might help. It solved the issue to some extent for a lot of users.
Access the phone dialer and dial the code *#*#4636#*#* – don’t press the ‘call’ button. After acouple of seconds the test menu will appear. From this test menu, select ‘phone information’ and scroll down to the first dropdown menu.
Select GSM auto (PRL) rather than the likely setting, which will be WCDMA/ GSM Auto. Restart your phone by powering off and back on again. Check the test menu again to ensure the GSM auto (PRL) option has been retained. If not, set it again as above.
That said, installing a custom ROM improved my reception stability ten fold. I strongly advise it.

I'm pretty new to this stuff and don't really know what GB or ICS is. But I'm sure I'm on the stock rom and unrooted since I haven't changed anything on the phone since I got it.
I tried your suggested method but unfortunately it didn't make a difference. It also disabled my MMS capabilities again :-\

Find in settings updates. There should be an option to manually check for updates, select that. If it comes up with an update, make sure you have wifi and enough battery.

Checked for updates and it says my device is up to date.
Before this phone I had an HTC HD2 and ran AmeriCan Android on it but I can't say I was a big fan of the idea of having to run another system after starting my phone. It was a big reason for why I decided to get the sensation in the first place.

Hmm.. I guess you will just have to wait for the ICS update, which is the latest operating system at the moment. (Kind of like Windows XP vs Vista)
Other than that I have no idea why you have not received the update; out of interest which country are you in? And which carrier are you on? Is your phone SIM free or carrier branded (contract as well)?
You will just have to wait the update out. However, you are welcome to root your phone like me (Google it), and I can possibly show you in the right direction if you send me a PM.

[Q] G2X radio broken

I have CM7 installed on my G2X and the radio turns off on its own -- it reports no signal. In order to get the radio working again, the only thing I can do is reboot my phone.
Also, to even get the radio working, I had to install "APNs Backup" from the market.
I am running android 2.3.4 on CM 7.1.0-RC1-G2x
My baseband version is:
M6600A-SCAUNTZ-2.0.9720T 1 [MAR 07 2011 16:00:00] MP:TRULGE_08.09.02R_MDM
Has anyone else had this problem? Can anyone confirm whether I have the p990 baseband instead of the p999 baseband by accident? (as reported here http://forum.xda-developers.com/showthread.php?t=1037098)
Lastly, can anyone help me flash the BIN_LGP999AT-01-V21e-310-260-JUL-15-2011+0 baseband from here:
http://forum.xda-developers.com/showthread.php?t=1037120
Specifically, I am not sure which of the two BIN files to flash, and what the correct nvflash command is (which partition does it go to?)... I can't use smartflash or any windows tools...
I have done a lot of searching and I couldn't find anything to help me out, but a few topics that are relevant are here:

What radio are you talking about?
APN is a known issue for CM7 based roms.
The baseband you have right now is a g2x baseband, though, it was the one when it came out with froyo.
Why you have to partition or repair partition on your phone if it has mo issues with partition?
Sent from my Calculator with Android.
CM7 or any 2.3.4/2.3.5 ROM for the G2x is known to have that issue. They are working on it currently. The APN's Backup App works for me tthough.

FatalityBoyZahy -- do you do anything special with it? It allows me to actually get reception (I can't without it) but my radio will still drop and force a restart. Do you have any special settings on it? When the radio drops the tool no longer has the list of APNs and I have to "restore" to get them back.
I was using the experimental (RC1) ROM so I just flashed the 155 nightly. So far a few of my network issues are solved. I'll update if it's completely solved tomorrow.

I could send you a copy of my APN's if you'd like. You'd just need to put them on the SD Card, and restore them through the app. Shoot me a PM.
I have the same issue. My phone randomly looses connection even in good signal areas. Only way to get back on the network is to toggle flight mode or reboot.
This is a known issue on all Android phones that has persisted throughout all Android versions. Google has worked on the problem and it has gotten better, but they haven't been able to exterminate the bug yet. This phenomena occurs when the 3G signal is weak and the phone switches back and forth from 3G and Edge frequently. Eventually the phone just shuts down the radio due to it switching too much. This is the Android OS commanding the radio to shut off. It is not a hardware issue at all. I have had this issue on every Android phone I have owned. Ironically, the only phone I haven't seen the issue with yet is my G2X running stock GB. The best way to alleviate the issue is to install "Network" from the Market and set the phone to 3G only. If your custom rom has a 3G only option just set it there. There is also an app called "3G only" that accomplishes the same thing. Since you are locking in 3G the phone won't switch frequently and the radio will stay on. You can do the same thing by setting it to 2G only, but who would want to do that.
Network: https://market.android.com/details?id=de.mangelow.network&feature=search_result
3G Only: https://market.android.com/details?id=com.mobnetic.only3G&feature=search_result
I think my issue is more severe than it is for you guys. Fatality - when my radio goes out, nothing but a reboot turns it back on. Not airplane mode, not toggling data on off, not changing apns. In fact, when the radio turns off any menu pertaining to the radio freezes and asks if I'd like to force quit it.
Also, I doubt that this is the long term Android bug. I've owned probably 10 or 15 android devices and I have seldom had to restart the phone because of this. For my g2x, I have to reboot literally 15 times a day.
I had two more leads I am trying.
One was that I have a 5 year old T-Mobile SIM in my g2x and I read somewhere that an old SIM could be a problem. No such luck, the radio has already turned off with a brand new SIM.
My second lead is my baseband. I have a March 7 baseband, but the two basebands online for g2x are March 17 and a later one. So, perhaps I do have the wrong baseband?
Thanks,
Ben

Oops I forgot to respond about jboxers suggestion to limit to 3g. It didn't work, either.
The network app didn't seem to have a 3g only mode, the 3g only app didn't limit my phone to 3g (it was still 4g) it only turned data on/off and also the radio still turned off, so I tried using the phone's 2g only mode and that immediately killed the radio.

3G and 4G on HSPA are inseperable. '3G only' will give you '4G' also.

As another poster already said on TMO 3G and 4G are the same thing. In fact, TMO doesn't have real 4G. HSDPA+ is fast but it is not true 4G. In some countries it is referred to as 3.5G and here in Thailand they are calling it 3.9G.
The network app does work. You scroll down and selected "WCDMA" only. That is 3G/4G. That will lock the radio into 3G and 4G only. The 3G only app will lock it into 3G and 4G only. There is no way to say 4G only, because it is not real 4G. If TMO had LTE that would be a different story.
Ah, that's good to know that 3g=4g on t-mobile. How come sometimes my phone says 4g and sometimes 3g?
Anyway, I wish that was the issue
Does anyone else have any ideas of what it might be?
What baseband version do you guys have on your G2x? Does anyone else have the same baseband version as I do?

HSDPA=3G, HSDPA+=TMO Pseudo 4G. HSDPA+ is an enchanced version of HSDPA with faster speeds but not true 4G. Most devices display an "H" but TMO had it programmed to "4G" to pretend they offer 4G service. Both are versions of WCDMA, which is what GSM 3G is.
I found this thread that has another kernel that supposedly fixes the APN. I haven't had my kernel drop yet, but it's only been 10 minutes Here's a link to the kernel:
http://forum.xda-developers.com/showthread.php?t=1229932
For install instructions, read the instructions in the linked code.google.com issue tracker:

I used:
adb push boot.img /sdcard/ && adb shell dd if=/sdcard/boot.img of=/dev/block/mmcblk0p5 && adb reboot
and everything worked fine (don't forget to clear dalvik cache on reboot).
To run the script he linked to, download ScriptManager from the app store.
It fixed my radio! Though it did kill wifi.

It is cause you are using the wifi calling it has bugs and drops calls it also all ways runs in the background even when wifi is off I suggest unistalling it via titanium backup or at least turning it off when making calls

It couls also be the sim, try yours in a differnt phone and see if the issue stays with the sim or not
I read that some users have this issue too, but couldt find solution
I have the same problem with ARHD 6.2.1
My workaround is to disable 3G mode. It seems that the phone prefers weak 3g cells over 2g cells with good signal strength.
Install one of the GSM Monitors from market. If your signal strentgh ist -100dBm or more, phone calls get unstable. After switching to 2g mode (Settings - Mobile Network - Network Mode - GSM only) I have -75 - -90dBm now and more available cells than before.
Phone Calls are stable now.
Before that I tried to downgrade to another radio but no luck. I never had this problem with ARHD 3.6.8 - 3.6.13 that I used before.

Did you guys purchase you handset through a mobile carrier in your region, or purchase it online from another country?
If it's the latter, you may need to look into flashing a more appropriate radio for you region.

[Q] 3g/4g Switching Bug? Post here

OK, so I'm trying to round up all of those who are experiencing the 3g/4g radio switching bug. In a nutshell, it's this:
In the middle of a data-intensive process, the radio will switch several times from 3g to 4g to 3g to 4g, and over and over again. Often, it will cause disconnects, failed downloads, and interrupted streaming audio, etc.
If you are experiencing this bug, please post in this thread, and be sure to include whether you have the US or EU version of the phone. I want to consolidate all those with the problem into a large thread, so it can get more visibility.
Hi,
I have exactly the same problem with my One S.
When the phone idle, the connection is 3G but when i use the data, it switch to 4G/3G/4G/etc...
As you said, it cause disconnects and and sometimes resolving errors.
My phone :
HTC One S 1.53.401.2 (stock rom)
Kernel : 3.0.8-01050-ge2a40ab
Baseband : 0.15.31501S.19_10.12.31501S.06L
Build : 1.53.401.2.CL47230
Operator : Free (France)
Same problem, with a SH23 EU phone and firmware version 1.53.401.2.
It switches from 3G and H (which is more 3.5G or 3G+ than 4G here), but I didn't experienced connexions problems (but haven't had many opportunities till now)
EDIT: Sorry, didn't see that another thread already exists in General forum.

I'm with the same phone and same behavior exactly.
I've already notified HTC about t a week or more ago.
I believe this is due to EU software. My reasoning is this:
On my T-MOUS One S, everything is fine on stock firmware with root. I NEVER experience this problem, the only switching I ever get is when I'm on a fringe area with NO 3/3.5G. As soon as I flash a rom that is based on EU firmware (all of them basically), I can't run speedtests without data being interrupted and the status bar shows switching from H to 3G repeatedly. No, this is not a scientific test by any means, but once again I have no problems whatsoever on my T-Mobile US stock rom.
T mobile does have the bug
It is because the T Mobile base is programmed to not switch from 4g but I assure you I own the phone and if you do speed test you will see this bug is definitely present..
I've been doing speedtests since I bought the phone.. it never happens on mine
whether you like it or not..
Guess you have the magic device that does not have the bug which everyone else has..even though tmobile acknowledged the issue already as well as the people with the EU version which also has the bug..

Airplane mode is a feature of the phone and turns off all radios. You can hold the power button and choose airplane mode or use the quick toggle in the notification window. Since it sounds like you may be in an area with weak 4G, you can also use an app called Phone Info to set it to CDMA auto (PRL) under Device Information. You can also change it back to LTE/CDMA/EvDO if you want it to switch as normal.
With the Verizon S3, is there the need to do *228 (or *22899) ? I did this every so often on my old HTC Incredible.

Doesn't work on LTE devices. A reboot essentially does the same thing. Some have recommended pulling the battery with the phone on, removing the sim card for about 30sec and then putting everything back in.
Thanks, I know what airplane mode is, wasn't sure where the APN setting was. I will look in to phone info though.

Are you guys also experiencing the "No Sim Card" and "No Network Connection" issues?
Or is this an entirely different issue?
When this phone goes to 3g, it does seem extra bad on how long it takes to switch back to 4g. i have areas where i live where it goes to 3g when going in between hill (less than a 50 foot stretch) and it will not go back to 4g for over 10 minutes if i dont manually do it. Not to mention my LTE never goes above 10 mbps on the best days
Somewhat related...If you use Anycut to create a shortcut to IOTHiddenMenu, enter the ##DATA# Menu, edit. Under "Advanced", there is an LTE toggle, under "Other" > "HDR/1X" you can set the phone mode, and then under "Other" > "LTE APN Settings" you can somewhat modify the APN settings, reset and discard. If it asks for a password, it's 000000.
I gave these a try. I'm trying to find a way for my phone to favor 4G when there's a 4G signal, no matter how weak.
Yesterday I did a test, 3G with 3 bars vs 4G with 0 to 1 and 4G had consistently faster download speeds and shorter ping times. The upload varied from similar to 3G to slower.

probably easier said than done. The phone info app can force LTE but you lose voice and text.
Ya I found that out yesterday when testing speeds. I went to send a text then make a call and no luck
Otherwise 4G service where I live could be excellent at one spot then a mile away no service. If I had excellent 4G consistently I'd consider GoSMS which I believe has the option for data text and also a separate VoIP app
Ah well hopefully something will be figured out eventually. With a strong 4G signal 4G is considerably faster and more consistent than my 20mbps home broadband

send it back
I've had similar issues with my network. I had no 4G in 4G areas, but mainly my wifi would disconnect randomly and 3G also dropped to 1X a lot. I ended up having to send it back and get another one. So far no issues. Also the new ones have an "Updated" sticker on them. I think it was just a software update they applied, but I never got the OTA on my old phone.

Your new phone came with an already updated firmware version I535VRALG1 instead of the original version I535VRALF2.

I'm having the same issue with my second replacement phone... My first one was replaced for an entirely different issue (loose home button).
Did you get the "No Sim Card" notification and "No Network Connection" message?
I think I might have to return this one as well...

Not sure if anyone will have the same luck I have with the "Phone Info" app, but with it I was able to get my 4g service back and my phone is functioning normally again. Just open the app, select Device Information and scroll down to "Set preferred network type" and select "LTE/CDMA/EvDo" then get out of the app.. 4g should return shortly there after. When I looked at it, my device was set to "GSM/CDMA auto (PRL)"

[Q] Noob question, i think...

WCDMA only
GSM Only
GSM/WCDMA auto
what are the differences? i live in an apartment and usually i am in a 2G situation w/T-mobile and the option selected is GSM/WCDMA auto, but whenever i switch it to GSM only, 4G appears, then i switch it back and i am on 2G, i know this may sound very very very noob but i need help understanding that, can anyone help me?
Ha..use the the one that works best. Google search will explain the differences

I could be wrong but I thought GSM was 2G and the other is 4G. The auto option will select the best available. 2G uses less battery but it's obviously slower.

Thanks, I was wondering the same thing

I was wondering the same thing and settled on auto but found out it was probably my radio version. There are many threads on that in the developers forum, I believe. I flashed a different one and am running a bit faster now. I used about every ROM around before I settled on Viper as my favorite but MUIU had the best battery life without messing with too much IMO. You can get CID checker as a free app in the google play store and scroll through to find your radio version and hboot... trust me you may need them at some point so it's best to get them now.

Well i mean yeah your right, it's just that whenever i set it to GSM i get 4G automatically but if i select WCDMA i get 2G and 4G whichever is stronger i think.. or is it my imagination... =/
