It would be nice to be able to set the 4g to 2g threshold settings. At my work if I forget to manually switch to 2g, my phone stays on 4g (it still finds a weak signal so it doesn't switch to 2g) and I miss all calls, emails, sms....
Just to confirm, there is no way to tell the g2x when it should switch from 4g to 2g right?

There are apps like Tasker that allow you to set things depending on your GPS location or times of the day. I don't know if it specifically lets you set when your phone goes from 2G/4G but I think it does.

Right I was thinking about that. What I ment was switch from 4g to 2g based on signal strength. I'm sure there is some kind of a limit in place to know when to make the switch. It would be nice to be able to modify this.

Not sure about a way to manually set the thresholds but there is one setting you can change that's supposed to require a stronger WCDMA signal before it switches from 2G. On your dialer, dial *#*#4636#*#* and go to Phone Information. Scroll down to "Set preferred network type" and select "WCDMA and GSM Auto" with the stock rom. I think with CM its called something like GSM Auto PRL.
The difference from WCDMA is that Auto requires a higher signal strength threshold to use switch to 4G. Not sure what those thresholds are and I haven't noticed much difference but I have pretty good signal everywhere I go.
It.wouldn't hurt to try it though.

How do you actually save that setting?
Oh and a better shortcut to that menu is download anycut from the market, add shortcut to desktop using that program and tap activity then look for testing.
G2x with CM7 and faux kernel. NONSENSE!!!!

The setting should stick until you change it again. Is it changing automatically on yours?

I changed the settings a few times when I close the setting it always saves the setting I picked.
Is it supposed to save these setting after a reboot or when turn the phone off.
I noticed while on WI-FI it's always on GSM

Toggle to cdma prl in York LTE settings and reboot. If I have LTE set on I get 1x all the time. Not sure if its the real problem or fix but seems to work for me. I'm also in a 3g area.

Same issue here.
This morning I wake up, and my thunderbolt is stock on 1x. If I switch to 4G, it will do 4g, but back to CDMA only, and stuck on 1x. I have 4G at home, but leave it on 3G because I normally am at work with no 4G coverage.
I flashed the stock mr 2 rom just to confirm and used the official radio just to be safe. No change.
Googled around a bit and here is a fix that worked for me...
Dialer -> ##778# ->Call -> Edit -> 000000 -> modem settings ->Rev A
Switch to enable from eHRPD and then hit back once. Menu->Commit.
Solved for me, but I don't know if it has adverse effects...

Did the exact same thing. Doesn't have adverse affects other than with losing benefits of LTE.

This makes your phone use the "old" version of EvDO. Basically what all 3g phones that don't have 4g radios use. If your area doesn't have 4g, doing this change shouldn't effect you at all and might get you 3g if you are stuck in 1x.

1X here all morning too. I'm in San Francisco.
On the plus side, my DL/UL speeds suck, but ping is 9 ms, so Mobile Hotspotting is still relatively fast.

Dont think you can use data while on a call when using EVDO, like you could on LTE.

You can in 3G with the Thunderbolt. I did it yesterday. I work in 4G but live in 3G, but this feature is what finally made me pick the TB over the Charge.
I started this morning with the 3G/4G toggle on 3G only, to save battery, and around lunch I switched 4G back on and it has been there since... I haven't had issues with 1X. Must be a regional thing.

Verizon Roaming?

Ok so I just got this phone from Verizon and I did not now that the service would suck, I've been all through the settings bad even using roaming apps but nothing seems to allow me to roam and get a decent reception...
Does anybody know how to unlock the roaming option from the settings?

Have you tried using "Roam Control" app? There is no setting built in to force the roam feature.

dude, i just went thru the same exact thing today. i even went totally stock, kernel, recovery and everything, still stuck in roaming.
i spent hours then i did the factory reset code on the dialer ( *#7780# (Factory Reset) ) and it worked again, i was so happy because i was thinking that i have to deal with the bs with sending the phone back or getting a new sim if that was the case. i hope it works for you also.
EDIT: i thought you were stuck roaming, not that u wanted to roam hahhahaha nevermind

I take back what i said. so basically im roaming and can make phonecalls but i get no network access and even though my phone says roaming voice and data i cannot access data...
here are my screen shots

Unable to get 4g back after using Phone App.

I selected the (CDMA auto PRL) for 3g only then didn't like it so i wanted to switch back but it would not let me. so now i'm stuck on 3g selected (CDMA auto PRL) every time I try to switch the setting to something else it just reverts back. Did anyone else have this issue? Please is their a fix? I need help to get the 4g back on my phone. (Galaxy S3 Verizon, rooted)

I had to reset the phone and install a different rom to make mine work. Hopefully that helps.

The same thing happened on my non-rooted Verizon S3 after using Phone Info app. Verizon tech said my phone was defective. When I went into Best Buy, they started switching my phone to a new S3 and it still did it...found it was the sim card. After I got a new one, it's been working ever since.

I have posted the fix in about 4 other threads...you need to reprovision your device with the dialer code

This wipes data so have a nandroid ready.

I don't think that phone info app has been updated in years. Was never meant for new ultra high end phones. And not to sound rude but those menus were never meant for us to play with.

That menu is how I ****in' ripped off VZW and their tethering app for the longest time with my old X2 before I got pissed off at it's random disconnects and just started using wifi tether for root users.
Ahhh.. the memories. Good times.

idk if this is the same but i used the phone info app on my fascinate and changed it and couldnt get 3g so i went to mobile networks under wireless and networks
in settings and clicked data enabled

I haven't had any problems with the phone info app! Use it daily and it's never gotten stuck on 3g.

Does this Re-provision code work with 4.1.1, I've been reading that it only works with ICS builds? I can't get 4G lte ever since rooting my phone and I've tried every thing but this. I don't want to try it though unless I know for sure that it works with jelly bean.

Id say delete the phone info app or wait until it's updated to be compatible with jellybean. 3g is almost then same as lte anyways at least with my phone I almost always have a strong lte signal. The s4 chip in the gs3 was designed to be a power saver on lte compared to older chips

Ok, so if I delete the app is my phone still stuck in 3g mode somewhere in else in the phone then? I guess what I mean is does deleting app force the phone to run off the APN settings? And if this still doesn't work can I use the re-provision code ( *2767*3855#) that I saw earlier in the thread? Finally is there a way to simply check if my SIM card is screwed?

Is there a way to turn off LTE CM10?

Yeah that's right turn it off! Seems they just added a tower in my area but I get crappy signal in my house and on HSDPA+ I get full bars. I thought this phone automatically connects to the "preferred network" but LTE in my house sucks and it keeps connecting to it.

I tried that on multiple radios and can't get it to stick. I also tried disabling it with the optional LTE toggle but even with it off the damn phone keeps connecting to LTE, gives me 1 bar and about a half meg down. I get full bars and almost 10 meg down with H+. Its not just the cm10 ROM because I went completely stock with your very helpful stickies and it does the exact same thing.
