Yep, screen separation. Mine started doing the same thing. Then one of the OTA updates bricked it so I had to RMA it anyway. I figure it will only get worse so your probably better off getting a new one. You'll probably get a replacement before I get mine back from RMA. Kind of worried about how the repair will turn out too.
[Asus  Eee Pad Transformer Prime] AnnoStar:
Thanks,

I knew it isn't normal, but I just can't be bothered returning it. But I guess I should, the first Asus product I've ever had a problem with, shame.
[Samsung Galaxy Nexus] taylerdurden:
Anyone noted that? In the secret menu (you can access dialing *#*#4636#*#*, in the first section) with the 4.0.4 'WCDMA Preferrer' is selected, and you can´t change that because it returns to the default value. In the 4.0.2, the default was GSM/CDMA Auto (PRL).

I think that is important because if affects the battery life in standby. In the Nexus One, the battery last much longer in GSM/CDMA Auto (PRL) mode than WCDMA Preferred.

What do you think guys?
[Samsung Galaxy Nexus] MatAuc12:
I did notice the change, but you are wrong saying it affects battery life. Theres a reason you cant change it, let it be.
[Samsung Galaxy Nexus] taylerdurden:
It affects the battery in the Nexus One..

Nexus One and Galaxy Nexus are two different phones with two different sets of hardware made by two different manufacturers.

The sooner he realizes that turning off wcdma means no 3g, the quicker we can chuckle about it.

And yeah, 2g is better on battery.

Edit: That was a bit mean, but really, Google this a bit.
[Samsung Galaxy Nexus] marvi0:
Hmm, interesting I remember on the first htc desire and the htc hero, it was recommended to use gsm auto prl, as it saved battery, and their was an interesting thread about how it worked, and I use to use an app "network ", by Phillip, and it helped to chose the gsm auto prl, but when I tried to use the same app, on my galaxy s2, it wouldn't work anymore, as the gsm auto prl setting wouldn't stick, so I suppose the phones nowadays use a completely new framework. I just set mine to auto select Gsm /wcdma if am in a place of good coverage and when coverage isn't good, I just set it to gsm. My two cents.
[Samsung Galaxy Nexus] taylerdurden:
I am agree, but there is something strange. People who have received the official ota with all stock, told me that they have the GSM/CDMA Auto (PRL) activated, like in 4.0.2. But, like me, people who have updated whit the full system image have WCDMA Preferred and cannot change..
[Samsung Galaxy Nexus] andQlimax:
I updated with the ota and also wcdma is selected... I would say it's better than the previous (ambiguous) GSM/cdma..our phone is not cdma..

Probably the best option to save battery would be GSM auto prl...

[Samsung Galaxy Nexus] taylerdurden:
What option had you before the OTA arrives to your phone? Or have you update the OTA manually?
[Samsung Galaxy Nexus] odin13:
Same here...i flashed the image from Google and can't change it although when i select 2g only in settings menu it does change from wcdma to gsm only...

Didn't check this menu after updating from 4.0.2 to 4.0.4

*i have gsm gnex..on 4.0.3 roms the setting would be gsm/cdma

[Samsung Galaxy Nexus] taylerdurden:
Since I buyed the phone, that means with 4.0.2 and 4.0.1, I have had GSM/CDMA Auto (PRL), it is asi the phone comes becuase I kept it all stock. But, fur installing the 4.0.4 I have flashed the full image, and it is then the change has come. It is very strange, because people who have received the OTA officially, keeps the GSM/CDMA Auto (PRL) selected..
[Samsung Galaxy Nexus] DaLoona:
If you want some powersaving from switching data/bands , get a custom rom like AOKP 29, then you can set a powersave function to switch to 2g or turn data completely off, automatically when going to stand-by. Or get an app like juicedefender, it does the same.
[Samsung Galaxy Nexus] taylerdurden:
I only want to know why the OTA leaves the GSM/CDMA Auto (PRL) option active, and the full system image set WCDMA Preferred and doesn´t let to change it..
[Samsung Galaxy Nexus] :
I too have the same thing with AOKP Build 29.... it normally sticks to WCDMA Preferred.... but on AOKP Build 28, it sticks to GSM/CDMA Auto PRL....

can someone shed some light on this?
[Samsung Galaxy Nexus] Mawdo:
I did flash the FULL factory image from the google page but i have an option to change it ( and it have WCDMA PREFERRED pre-selected ) i have a GSM version and i have no idea which one is the best option....:confused:
[Samsung Galaxy Nexus] :
I think we all have the option to change it.... the question is, does it stick after you exit the menu? Can you set it to GSM Auto PRL, reboot, and it stays on that setting?

Let us know.
[Samsung Galaxy Nexus] Mawdo:
Here's a screenshot of the options but i have a extreme Battery improvement on this update "4.0.4" and i don't have any idea why...:mad:
[Samsung Galaxy Nexus] Mawdo:
ok i will check that

---------- Post added at 01:14 AM ---------- Previous post was at 01:09 AM ----------

NOPE it will stay as long as you didn't reboot the phone, but once you turn off the power it's gone :rolleyes:
[Samsung Galaxy Nexus] :
Wow, but it actually stays if you leave the menu, do other things, then go back to the menu, and you have GSM Auto PRL when you return?
[Samsung Galaxy Nexus] Mawdo:
The anser is YES

Anyone else? Why isnt this getting more attention?

You know people need sleep right?
[Samsung Galaxy Nexus] GibMcFragger:
Here is a quick rundown of the difference between the two.

WCDMA preferred: Device will use 3G and 2G. If the signal is weak, the device will prefer 3G.

GSM auto (PRL): Device will use 3G and 2G. If the signal is weak, the device will prefer 2G.

In short, both settings will have the same effect on battery life as the only difference is the fact that GSM auto PRL will switch to EDGE if the signal gets weak.

[Samsung Galaxy Nexus] neotekz:
im on aokp build 29(4.0.4) and when i change to gsm auto prl it does not stick when i exit and go back, always turns back to wcdma preferred. im not using the stock 4.0.4 modem i switched it to ugla4. is there another way to make it change to gsm auto prl, some settings in the frameworks or something?
[Samsung Galaxy Nexus] taylerdurden:
Tonight, from 00:30 to 10.30 the battery has gone from 16% to 6%. That´s a huge battery drain...
[Samsung Galaxy Nexus] andQlimax:
Thats what make the difference, on edge there is less battery drain than with a weak 3g

By the way there is no way to change the preference on the secret menu...at least in the stock 4.0.4 (is set to wcdma preferred, does not matter if you updated with ota or factory images, as someone was saying)

That is true, but it's negligible. How often are you on a very weak signal? I am never. :)

[Samsung Galaxy Nexus] taylerdurden:
1%/hour is high?
[Samsung Galaxy Nexus] neotekz:
depends what you have syncing like email, social media, weather, widgets updating stuff, location services on, wifi or 3g. kernel wakelocks will also keep your phone from going into deep sleep. i have nothing syncing except weather every 4 hours and i lost 2% last night, around 8 hours of standby. this is on wifi with the phone set to 2g.

as for the preferred network setting i wonder if htere is another way to change this, there must be a file or database somewhere we can edit to change this value besides using the secret menu.
[Samsung Galaxy Nexus] taylerdurden:
Now when 90% of the people have received the OTA, I up the thread, so the people can share their experience with this setting...
[Samsung Galaxy Nexus] andQlimax:
thats wrong, never trust people :p

4.0.4: WCDMA and cannot change

4.0.2: GSM/CDMA auto prl and cannot change

at least that is for the GSM version

does NOT matter if the update is done with a full image or with the ota
[Samsung Galaxy Nexus] :
Yep... thats it....

I mean my battery life has improved, so I'm not making that big a deal of it.... but I still want to know why ...
[Samsung Galaxy Nexus] adrynalyne:
Because it was probably always like that, internally. Google merely updated the phone app to display it correctly.

GSM/CDMA is for LTE devices that use both tech.

CDMA tech for voice and EvDo.

GSM tech for LTE.
[Samsung Galaxy Nexus] vro25:
I was on a yakjuux build and I flash a factory (yakju) 4.0.2 image to my phone. It was running great on GSM/CDMA auto (PRL).

I then got an OTA upgrade to 4.0.4. When the upgrade completed the network mode was now on WCDMA Preferred and my radio shuts down when the screen goes to sleep. As if a non-working phone wasn't enough, my battery drain goes down 4-6% an hour (from 1% on 4.0.2).

If I leave my phone alone for 5 minute and then turn it on, the radio will display signal (I think this is just a cached image) but then second or so later I will see an X in the signal meter. Also, calling my phone when the screen is off (after a few minutes) will send me straight to voicemail.
[Samsung Galaxy Nexus] pewpewbangbang:
WCDMA 4.0.4 OTA update

My batter life was good though. Haven't fully tested it as I just got the phone.

But from the way batter came, from around 50% to dead. I got over 2 hours display time with around 7 hours on battery.
[Samsung Galaxy Nexus] E15i:
Why do you even care about it? a have some android phones till now, never used the WCDMA preferred mode as it just stupidly drain battery.

just use GSM only (also my network support EDGE), it's dine for sync and email, if I need to browse, then switch to WCDMA only (also if the signal weak, it drain more battery in any mode).

also PRL :

http://en.wikipedia.org/wiki/Preferred_Roaming_List
[Samsung Galaxy Nexus] efrant:
I don't believe that is exactly the case. These are the options on a maguro device:

WCDMA preferred <= this will work on GSM and WCDMA, but prefer WCDMA if the signal is weak

GSM only <= this will work only on GSM

GSM auto <= this will work on GSM and WCDMA, but prefer GSM if the signal is weak

CDMA auto <= not applicable to maguro devices

CDMA only <= not applicable to maguro devices

EvDo only <= not applicable to maguro devices

GSM/CDMA auto (PRL) <= not applicable to maguro devices

Unknown <= not applicable to maguro devices
[Samsung Galaxy Nexus] adrynalyne:
Arent folks wanting to use GSM/CDMA auto (PRL), though? Thats what the thread started with anyway.
[Samsung Galaxy Nexus] efrant:
IMM76D changed the options that were in that menu (vs. ICL53F).

Keep in mind this is just my interpretation: Some of those options were legacy menus. In IMM76D, they changed them to make them more up-to-date. In ICL53F, there was no GSM auto.
[Samsung Galaxy Nexus] vro25:
On yakjuux 4.0.1 (ITL41F) devices the default is GSM/CDMA auto (PRL). This is also the case on yakju 4.0.2 (ICL53F).
[Samsung Galaxy Nexus] neotekz:
gsm/cdma prl and gsm auto prl are different
[Samsung Galaxy Nexus] efrant:
The thing is, the options have changed between ICL53F and IMM76D.

The new options are:

WCDMA preferred

WCDMA only

GSM only

GSM auto

CDMA auto

CDMA only

EvDo only

GSM/CDMA auto

Unknown

The old options were:

WCDMA preferred

WCDMA only

GSM only

CDMA only

GSM/CDMA auto

So, as you can see, it appears as though they updated the options (from the legacy options in 4.0.2). The last 5 options in the current list don't really apply to a GSM/HSPA GN, and the GSM/CDMA auto setting will yield the same result as the GSM auto setting.
[Samsung Galaxy Nexus] trueSherlock:
DTMF issue

I don't know if anyone else has noticed this, but in the WCDMA Preferred mode, the DTMF tones don't seem to work properly. I am not able to dial in any conference call codes. And have to resort to Skype to do it.

It works properly when I set it to GSM/CDMA Auto (PRL), but the setting somehow gets reset to WCDMA Preferred.
[Samsung Galaxy Nexus] vro25:
I wouldn't think it would make a difference either - but I'm stuggling to identify the issue. What I know is the phone was working fine on its default setting of GSM/CDMA auto on 4.0.2 and now on the WCDMA Preferred setting it keeps losing it's radio.

Different radio images don't make a difference, seems to be 4.0.4 related.
[Samsung Galaxy Nexus] efrant:
Like I mentioned before (and I don't know this for certain), but GSM auto (or GSM/CDMA auto if you so desire) will tend to favour a 2G signal over a 3G signal when the signals are week, which WCDMA preferred will tend to favour the 3G signal. Not sure if that helps with you troubleshooting though.
[Samsung Galaxy Nexus] neotekz:
not sure about anyone else but i would love this option and not sure why google doesnt let us do this. the 2G signal is stronger in my house but the GN keeps going to the weaker 3G.

you are losing signal when the phone turns off? that could be a different problem. since you are rooted try this, download franco's kernel and run it with the smartflex option off or turn min cpu to 700mhz.
[Samsung Galaxy Nexus] efrant:
You can do it. You just have to do it every time you boot.
[Samsung Galaxy Nexus] andQlimax:
once u exit (back button) from that screen, it become wcdma preferred again, so i though that menu doesn't change anything at the moment
[Samsung Galaxy Nexus] twissii:
Yes, it works:) 100%

[Samsung Galaxy Nexus] neotekz:
bump...going to keep this thread alive so hopefully some dev or someone can figure out a way to be able to switch the preferred network to gsm auto prl.

im willing to give $20 to anyone that can get this working.
[Samsung Galaxy Nexus] efrant:
Although it seems to be for HTC devices, this may be of interest.

In HTC devices anyway, there seems to be the following entry in the build.prop file:

ro.telephony.default_network=0

With:

0 = WCDMA Preferred

1 = GSM Only

2 = WCDMA Only

3 = GSM/CDMA auto (PRL)

4 = CDMA / EVDO Preferred

That entry is not in the build.prop of a Galaxy Nexus.

Maybe adding this line to the build.prop file could change the setting.

If you are going to attempt this, make sure you make a backup BEFORE changing your build.prop.
[Samsung Galaxy Nexus] neotekz:
thanks ill test it out and report back. can add that code anywhere in the build.prop? can i do this using root explorer or do i have to pull the file to modified it?
[Samsung Galaxy Nexus] efrant:
It should be added anywhere in the ADDITIONAL_BUILD_PROPERTIES section, and yes, you can do it in root explorer. Reboot and reboot again, then try it out.
[Samsung Galaxy Nexus] neotekz:
didn't work, the code stayed in the build.prop but nothing changed when i checked the secret menu
[Samsung Galaxy Nexus] efrant:
Thanks for testing. Kinda figured it would only work on HTC devices but it was worth a shot.
[Samsung Galaxy Nexus] eromine:
I am on 4.0.4 and my gnex is stuck on GSM/cdma auto prl and I always want to set it at GSM auto prl since my battery life greatly improves. I can change it and it survives leaving the menu but sadly it does not survive reboot. My key point here is it is not set at wcdma preferred like others and I am on 4.0.4. This is with the foxhound 4.0.4 rom never paid attention to the setting with stock 4.0.4 prior. I have a GSM nexus on at&t with base and xxkk1 if that makes a difference.

I'd imagine the telephony.lteOnCdmaDevice=1 would be fun to play with.
[Samsung Galaxy Nexus] efrant:
I don't believe that setting will do anything given that a GSM GNex does not have either an LTE radio or a CDMA radio built in. Do you have any information indicating that it will do something?
[Samsung Galaxy Nexus] zeppelinrox:
Upon further investigation the telephony.lteOnCdmaDevice=1 merely turns on lte and 0 turns it off.

I had hoped that it may have had available similar options as ro.telephony.default_network but that's not the case.
[Samsung Galaxy Nexus] neotekz:
any update on this? did IMM76I make any changes to the preferred network settings?

Common guys, there must be a way to change this.

Getting "WCDMA Preferred" to stick

Only had the device for a couple of weeks now, but lately I've noticed something unusual and irritating. I want the phone in "WCDMA Preferred."

Whenever the phone booted, it would flip back to "GSM ONLY" even though I manually override that to "WCDMA Preferred" each time. I tried multiple radios, multiple kernels - same effect. It *always* reset to GSM ONLY at boot :(

Then I tried putting it in "GSM Auto (PRL)" and rebooting.

Magic - it booted and showed "WCDMA Preferred." :) It now sticks :)

Counter-intuitive, but there you have it. Hope this helps someone retain their hair.

[Samsung Galaxy Nexus] andQlimax:
anyway they did some **** with that menu

the menu for me does nothing..i want to use GSM Auto (PRL) because 3g signal is so weak here, but there is no way..it always stick to wcdma preferred (and it switch often to 2g/3g with no data connectivity for a couple of seconds when it switch)..a real pain..

i can only go in system settings->mobile network-> and choice 2g only, but in this way i will never get 3g of course..

the real problem with this phone is the samsung radio baseband..they do phones and software from years, but they didn't learn nothing..
[Samsung Galaxy Nexus] Super Papero:
I can't do anything else than quote you.

I need sync and mail push service always active. Where I live/work 3G signal is weak and my Galaxy W continuously switch between 2G and 3G network depleting my battery about 10%/hour !

Using 2G only mode (called GSM only in my phone) my battery life is much much better just about 2%/hour.

When i drive my car, I use hands free with bluetooth and if 2G/3G auto mode is enabled a fully charged battery will be discharged within 4/5 hours! If 2G only is enabled the battery life is 2 times longer.

Samsung, you haven't learn nothing during all these years: I think you have to re-think something !
[Samsung Galaxy Nexus] Dr Byte:
Just an update: only one radio/RIL combination would "stick" for me on 4.0.4, that is... dvkk6 and the matching RIL from Telstra's 4.0.1.

Every other combination booted in "GSM only" mode and had to be forced.

I've just flipped to bigxie's 4.1.1 OTA ROM and am pleased to report that it boots correctly into WCDMA Preferred :)

[Android Q&A, Help & Troubleshooting] iLesboHD:
I was over looking the z4root app made a while ago. The app used "rageagainstthecage" to root devices. Now, thats pretty old. So maybe for all the newer devices we can simply replace the "rageagainstthecage" file with something like "ZergRush" and edit the apk's XML files to fit its needs. Would we be able to root devices up to 2.3.5 using this?

I'm running stock ICS, no roms, no root, just the regular version of Android that game on my Verizon Wireless Galaxy Nexus. Last night the battery drained and I recharged it while I slept using the charger that came with the phone. When I woke up I turned my phone on. The Google logo came up, it vibrated, and then the colors boot animation started. After a few seconds, the animation froze and then the Google logo came back up, it vibrated, and the colors boot animation started again, then froze. It keeps doing this over and over.

I can enter recovery mode and download mode. I made a video of my problem and posted it on YouTube:

Bah! new users can't post outside links >:-(

Is there anyway I can get my phone bootable without wiping the memory? Is there anyway I can access the contents of the phone on my computer while it is in this non-bootable state?

If not, then what is the best way for me to get my phone back to a bootable state? I have never messed around with rooting or roms for Android so I would need to know the best place to start. I have messed with custom roms for my old Treo and some game consoles, so I have some experience following tutorials.
