Dial code to enter service menu? - LG V20 Questions & Answers

I knew my Samsung dial code so I could go in and enable/disable certain LTE bands (band 12 is great for penetration for calls -but horrible on data speeds).
I would switch band 12 off while at work so I could get better speeds.
Just looking for the similar menu on the V20

##DEBUG# ##DATA# those are 2 of them.

Must be Sprint only

Those are almost universal dialer codes, they worked on my 6P only difference is *#*#DEBUG#*#* instead of ##DEBUG#..

Thanks. That worked. Now my phone is set to WCDMA/LTE only. Helps battery a little bit.
For the uninitiated put it back to auto when you leave urban areas and travel long distances in rural areas so you have access to edge.

None of these worked on my Verizon V20

This worked, now to figure out how to turn on/off band 12 as needed

Figured it out
To lock to a specific LTE antenna go to field test, Modem settings, LTE band selection and choose the band (band 4 and 12 are right now the only ones for me in DFW)
Then to revert back to where the phone switches go back a menu and choose Network mode and set it to Auto

The other menu code is 277634*#*
also on the other one... 918 is the T-Mobile LG V20 variant, try your specific model for your carrier.

Of course the #*918# is the model number if you didn't figure that out. So #*910# for the ATT variant.

Test menues, you can unlock the apn's in there to manually adjust them... And other stuff. Just be careful, their are thing that will mess up your phone too if you don't know to fix it.

Which menu options have you used for that?

So I can get into the menu, but if I try to select an LTE band it says FAIL, even for bands which are definitely compatible with my handset? What am I doing wrong? Thanks

Problem is if you do this you lose voice because of no CDMA. I tried this already a few hours ago.

You sure you put it in correctly sometime you have to put in ##3282## instead of ##3282# I thought that was a hard coded android thing though. It should be on all S3's heck it was on my old HTC Touch Pro 2 also and that didn't even run Android(well not officially anyway).
Try this (I used this on GNexus) and let me know if it works.
I know the dial code works, but I have T-Mobile so I don't have LTE.
*#*#4636#*#*
Click the "Device Information" tab
Scroll down to the drop down box and change it.
There is an LTE only option as well as LTE/WCDMA.
Give it a second to register. You can also click "turn off radio", wait a minute or so, it'll turn off. Click it again, wait a minute or so and it'll turn the radio back on. Usually jumps the change into effect. If you lose radio and it never comes back, switch it back to whatever you were using before.

That's funny I just started playing with the Testing menu you just posted before you posted it. I was about to post it when you beat me to it. By putting it on LTE only I think it kept my voice while giving me only LTE. I am going to have to drive around and test it and see if it ever goes to 3G or not. That might be the option. There is an widget that will take you to that menu without the code by pressing the 4G toggle on the widget. You can download it here:
https://play.google.com/store/apps/...rch_result#?t=W251bGwsMSwyLDEsImNvbS5qaW0yIl0.
none of the codes listed works...
the second one dials a number...
It would be a pretty good bet that this issue is carrier-specific. (One more example of confusion in this mashed-together forum.)
The code mentioned for T- Mobile works.

Well I got my phone listed in my signature. I think the OP is talking about Sprint only but I am sure each carrier may have a specific way to get to the phone test menu. I know that app I posted took me to it.
As far as the LTE only trick in that phone testing menu, I think it works for a while but does not survive reboot meaning you will have to reapply it. Also mine switched back to lte/cdma/evdo after a little while possibly when I lost a 4G signal completely. So I think this partially works or they are still turning on towers because I am definitely keeping 4G and getting it a lot more places then I did have it earlier today.

Edit: After making a run to the Grocery Store, I had the "LTE only" selection made from the Phone Testing Menu drop down list. I lost 4G in one area then got it back by the time I got to the grocery store. On the way back I made sure it was set to LTE/CDMA/EVDO and I got the same exact signal everywhere. So I don't believe changing the settings on that drop down on that menu do anything at all. I am guessing the phone software overrides those setting somewhere else.

Hehe, I have a monthly data cap of 2GB though, after which it get's throttled to 200kbit, so its not very useful, I would rather have lower ping rates and (a bit) lower speed to be honest.

			
				
I wish there was way to change the 4G symbol into LTE symbol.
LTE sounds cooler :lol:
I i am not in US at the moment, but noticed on T-Mobile US I have the 3G APN settings, here its posted different settings for 4G .. retest in few days.

Also, do you have the 4g option enabled? (You can check by dragging down the notification bar --> quick settings --> edit --> and selecting 'LTE'. Is it toggled on or off?)

Band 4 (XLTE) on Verizon...

My Nexus 6P seems to be refusing to connect to band 4 which is Verizon's XLTE band in my area.(LTE discovery, Pure Nexus 11/10) My Moto Nexus 6 works just fine. Is this expected? Work around? Any advice/ ideas are appreciated.
I'm in latest MDB80M and connecting fine on Band 4.
Sent from my Nexus 6P using Tapatalk
No problems with Band 4. Stock rooted MDB80K
Ok, thats good to know. I think it may be an issue wit Pure Nexus but I cant say for sure. I will troubleshoot some more. Thanks guys.
If you enabled Enhanced LTE option under Cellular Network and your device still refuses to connect to XLTE, call Tech support at verizon and have them add Advanced wireless option (Its free). When I switched phones on my account, that feature got dropped and tech support had to add back manually and now I am able to connect to XLTE on Band 4. But my download speeds are no where near as others have claimed
I went into my Verizon account and added Advanced Calling for free. It was not on my phone. I don't know if I had connectivity to Band 4 prior to that since I didn't check
Edit: Just to clarify, I currently have Band 4 connectivity.
Sent from my Nexus 6P using Tapatalk
How can you see what bands you are connected to? I am running pure nexus and can test for you.
Use the LTE discovery app and check your band.

Does the V20 support 3G video call with Samsung phones?

Hi to anyone with a V20 now.
Could you please tell me if the V20 supports 3G Video Calls? I am referring to the one that you dial directly with the dialer, not through third party apps like Skype or Facebook messenger.
Refer to the attached image here.
If it's not too much trouble, does it connect with Samsung Galaxy users?

Is that 3g video calling? Do you have build.prop file of your phone to send me to compare? I'm on LG V30+, but somehow don't have 3g video calling button in dialer like you all have. My carrier support 3g video calling, but doesn't support neither volte, vowifi, and hd video call. It works on samsung devices, but on mine lg doesn't appear button in dialer, or anything in settings
Anyone? And if you have root on v30, can you send me two things: one folder (you can send me like zip file), which is in path /OP/OPEN_EU (or in my case OPEN_AME_DS, or whatever is folder name of your phone); and build.prop file? I really want that video calling in dialer

Force 4g in s10+

Am kinda in an area where 4g is super fast and 3g is suppppper slow
Anyone knows how to force 4g in s10+?
You might be able to do that through secret codes but I wouldn't recommend it. There's a reason why your phone drops to 3G. It's probably because your LTE signal is too weak. If you forced your phone to LTE only you might end up with no signal at all. And if you're not in a VoLTE area you won't be able to make phone calls.
BTW there's a Q&A pinned on top for random questions. Easier than starting a new thread ?

Simple. Dial *#*#4636#*#*. Alternatively, just use the network app. It's basically a shortcut to phone info. Mine is set to LTE only. I'm from a place where every tmobile band is available, so connectivity is a nonissue.

For some reason *#*#4636#*#* is not working on my phone which is why I didn't suggest it. My concern with his specific case is that it did drop to 3G which causes concern. Mine never does. Would he not lose all data if LTE were not strong enough in his area?

This code doesn't work using the Samsung dialer. You can download the Google dialer port and then use the code and it'll work. This is one way you can force LTE always on. You will have to set the Google dialer as your default phone app and allow permissions as well as changing system settings.
