The stock rom lies .. or rather smudges the truth a little by showing a 4g (or H) even when your not really on that band. If your data speeds have not changed then I'd not worry about it.

Oh.. OK go into your APN settings and make sure its selected on tmobile. And then reboot. Also try turning on and off airplane mode.

I tried what u recommended but yet, still nothing =/

That's an ATT port, why dont you flash a ROM made for our phone? Darkside or Infamous are two reliable TW ROMS. AOKP or CM9 are two stable AOSP ROMS.

Well. You either need to try another radio. Or a different rom..

[Q] what app can do screen off auto turn to 2G,screen on turn back to 4G?

I want to save battery life ....

I do not know about the app but there is one problem. Sometimes I download large files and i do not want to keep my screen awake all the time. But if it switches the connection to 2g from 3g (or vica versa) it disconnects for one second and the download fails.. So that could be a problem for downloading large files.

if can set the timer,that problem can fix

Juice defender can do that I think. Haven't tried it myself I don't use that app anymore, but I believe there was an option in it to toggle between 3g and 2g. However, you have to have root access and a kernal/rom that supports it. Stock kernals don't support allowing you to switch between 2g to 3g without doing it manually yourself through the settings, so you probably need to find a custom one that does.

You'll need a mod ROM to get full use of Tasker for battery improvement. Stock ROM doesn't allow 2G/3G switching.
I understand that CM10 allows this.
Someone should confirm, as I've stuck to rooted stock rom in SIII and plan to keep the same on Note II.

*#*#4636#*#* and phone info

These menus won't work after JB update. Anyone know how to set phone to prefer 4g after the new update?

Tmo is edge or 3g. A very fast 3g they call 4g.
Download battery monitor widget. Add the widget. Click the widget. Select tests from the menu on the bottom. Select device information. Scroll down and you can set radio preferences. Back out using the back button and it will save your setting.

Right. No 4g per the actual definition. Good marketing ploy I guess. Is there a way to use a shortcut key code like before on ics?

I can't find it... I wonder why they removed it.

Someone put some list together of over 30 codes. You will have to search because I am posting from my phone. The battery monitor widget works great. I have used it on all my android phones. Give it a try.

I changed back to the LJ4 radio. It works the best for me. That may be the difference. Sorry. Did not think of that earlier. My bad.

Just flashed back to root stock jb and it works fine. Just off been a rom issue? Hmm....
Sent from my SGH-T999 using xda app-developers app

Just curious... What rom did you flash after jellybean update? I plan on playing around with some of the custom roms tomorrow.

Infamous. I dirty flashed it so that may have been why the radio would not stick but, I'm not sure. Wicked is a nice ICS ROM. I have tried a few of wild's ROMs too. They were good. Haven't tried many others.
Sent from my SGH-T999 using xda app-developers app

Agree on wicked. Can't wait for v8.

Just download Phone info from the market. It's so much easier than entering the code and easier then using battery monitor

[APP] Force Signal Refresh for Nexus 4 Running 4.3

After the recent update to Android 4.3, my Nexus 4 has been experiencing many irritating side effects. One of such bugs was loosing the phone signal every now and then. Sometimes the phone will come back online after few seconds. But more often than not, it wont come online and the phone remains without service untill I try to use the phone. In such a case, the only way to force signal search is by enabling Airplane Mode and then disabling it. Eventhough I have put the Airplane Mode Toggle in my PowerToggles home screen widget, enabling the Airplane Mode and then disabling it is a cumbersome thing to do. In order to simplify the process, I wrote a simple Tasker action and put that as a widget in homescreen. The action requires root access and Secure Settings Plugin (also the Helper) installed. Using the Tasker App Factory, I have converted the action to a standalone app and you can use it to refresh the signal manually on your Nexus 4 running Android 4.3. I have tested it on my phone and it worked without any issues. You can download the APK file from the link below.
PreRequisites for ths App to Work:
1. Root Access
2. Secure Settings Plugins and Secure Settings Helper must be installed

thanks for this. giving it a try now

I hope this thing work, i'm about to throw my nexus in the toilet :crying:

Installed.
I'll try tomorrow, and give a feedback...

Didn't work for me on
N4 4.3 JWR66Y
But plugging airplane mode on and off doesn't either.
The only way I can solve this it's turning off an on the phone..

Ohhhhh.. Mine is also the same build. But toggling Airplane made helps to refresh signal. No need to reboot the phone.. I saw another post to downgrade the system radio app to the one included in jb4.2 as the issue is only present in radio app included in 4.3. So if this is not working you may explore that option.

that seems to be the permenant solution until google updates the radio app to remove the bug. I had created an action to automatically toggle airplane mode if the phone remains without signal for a predetermined period of time. but that consumes a lot battery (especially if u are travelling). so don't use it now. If anyone want the action, i can post it here.

If you want to save battery and want to switch to UMTS-only then let me tell you that i tried that with settings in CyanogenMod but it did not improve my battery life at all. On the other hand if you're not using the internet much at times and want to save battery you might switch to 2G which would be enough if you only use the internet for texting. You may set that option in your phone's settings or with the menu you reach via entering the code *#*#4636#*#*
