[LG V30 Questions & Answers] JonnyTrulove:
So a little background on why I'm posting this. I have owned a G4 G5 G6 and V20, all on Sprint, and none of these devices can ever access the Phone Info section or "Radio Info" section as it's referred to on the Hidden Settings shortcutter App. I believe Sprint or LG removes access to this area on all LG devices. On all of the ones I've owned I can try and access the section but only catch a brief glimpse of it when I try to access using a shortcut app. It is always immediately covered by the same message every time which is: Note This application does not work on this device.

Now I just activated a V30+ a couple weeks ago which I received through Sprint's normal telesales channel and on this device I can get to and modify most fields in the section. I haven't seen other people posting about this so maybe it's standard for everyone with the LS998 Sprint variant and no one really cares or just doesn't have anything to say about it. If thats the case, my apologies for wasting everyones time with an unnecessary post .

If my access to this area is a one off situation and could help lead any developers or more avid tinkerers to any discoveries I'd be happy to test out some things together with anyone with more experience than myself. I've been holding off on attempting to unlock the bootloader and haven't done any PRL updates or resets just in case this access is worthwhile as I've been worried something is going to update and take away my ability to get into the section.

I've included some screenshots. I've cropped them to try and remove some of the more personal data but I think all the relevant sections are covered.

*** Below are some questions and thoughts I've had. I hiding the section it to keep things less cluttered for those that are just reading up but dont have any experience or opinion on the settings/functionality etc***​

If everyone can already get to this section, have you changed your bands or modified any of the settings and what results did you see?? I've been tempted to switch up some settings and run some tests but I'm being kinda chicken about changing anything because I can't find any info on people using this menu to do anything except screw up their coverage. A few example seems to be people on different earlier LG models that select USA but live outside the US and then cant get it back to their countries settings.

Here is a list of things I would like to examine more, or try out in these menus. Maybe some of you have already done such or have the same questions. Any feedback would be cool on any of these things or even warnings or endorsements. I would love to learn a bit more about this area and its possibilities.

Under the "Set Preffered Network Type" option I would like to change the current setting of LTE/CDMA/UMTS auto (PRL) to one of the other options and see what happens. I believe this area is relatively safe and can be switched back to the original setting easily. I'd like to switch to Global Auto Mode, Unknown Mode, GSM Auto mode and LTE Only Mode and run some speed tests and see what towers its connecting to in each.

There are four toggle switches, one of which is grayed out. This is the Video Calling Provisioned Switch. Curious if this would possibly become accessible in another mode, or if there was something i could change in a database editor that would allow me to switch this to "on".

The only setting I did change was the one DNS Check. It was originally set to disallowed and I switched it to allowed. I dont really know what changes or abilities this added or took away and have not seen any difference since doing so.

The SMSC when Refreshed will give me an 11 digit number in "" followed by a 3 digit number. It begins with +1 giving it the appearance of a phone number. I believe this has to do with SMS provisioning but am unsure and have not modified the info here.

One part I am very curious about is a grayed out button labeled OEM-specific info/Settings. I have searched like crazy just to try and find some info on whats behind that button and got nada.

In the additional menu section (the three dots) I have an option to Select Radio Band. When Pressed it takes me to a menu which sats "set GSM/UMTS band". This is the area I have found little about other than what I mentioned earlier about people getting locked out of their country settings. I have not touched this setting.

The IMS service Status of my device seems to not populate correctly as I'm listed as not registered or unavailable for all sections as seen in the picture attached. I could swear that a week ago I was showing "registered" but if so thats no longer the case.

Thanks in advance for any feedback.
