[LG V20 Questions & Answers] Team DevDigitel:
NO,

You need to accept two things.

1.) Currently if you root, you will not have a way to go back to FULLY stock and locked, but thats no fun anyways lol,

The real issue with this isn't going back to "stock" but having a "kdz" avalible for the recovery of a hard bricked device, or a soft brick that you cant understand how to fix. This is a restore img that you use a pc to push to phone to update, downgrade, or restore a lg phone, and sadly Sprint wont be releasing a kdz publicly, and its not coming so dont ask for a eta .

2.) The dreaded static on the bootup screen. We lack the developers on the Sprint/LG side of things that work on boot.img's,

This puts a ton of V20 users sprint and others in a bad spot. Where once ur rooted, you have static, and thats gonna ALWAYS be the case, unless you flash a AOSP rom like lineage. For this one, its just a nucence issue on reboots, its not really a issue for use, but man i can say I do miss having a custom boot animation on a reboot ( The static covers up the boot logo etc until you lock your screen)

The rest is regular root stuff. Some bugs etc. As far as getting LG apps back, and 2nd screen support..

The stock lg apps are back, and working as far as im aware. At-least on my rom ive brought back 99% of lgs apps that were gone, but some i didn't care to bring back. Like LG calculator and LG calendar. The Google replacement is better and more synchronization. But things like LG gallery and lg stock messages were things that should have never been pulled, and LG did in fact put them back on their G6. Smart move lg. There isn't any stock apps im aware of that wont come back at this stage.

2nd screen is proprietary, so unless devs build their own app using the 2nd screen code on lineage is stealing and xda wont accept that. So if ur leaving lgs softwear to flash a aosp rom you knew going into this that 2nd screen isnt a option, and if untimately your looking for pure android you should get the pixel xl or equivalent pure device.

There are some things with Encryption that could cause issues, mostly for those using some sort of high end email that checks your device security may not work, but thats going to be any rooted/unlocked device id say.

The statement : its not for the faint of heart: is kinda true. Rooting isn't for some, and you better be able to read/follow instrucions that are provided, and make sure you have a grasp before starting.

There is a ton of info on the site for users to read and digest as well as the V20 section has stayed pretty active with users and devs alike, myself being the latter. There's hope on the horizon for the above mentioned. Both KDZ and Static are works in progress, and unless a dev who is knowledgeable on these things comes over to the device its the same og team working towards perfection.

As far as OTA updates go, there are 0 devices on the market that get software updates from the manufacture after you have modified your system etc. This isnt just manufacture hating on the root, but also avoiding bricking ur custom device with a block update that is targeting files that are gone/moved/changed. So dont worry about ota updates as they are gonna break everywhere on anything that's rooted. The ota updates get pulled by devs, tested and implimented as fast as we can, but if you want the updates as the launch then dont root and accept the device as is. 99% of the time the bennifits of fixing / changing all the other things on the device to be delayed on a ota is worth it. Sprint is the 1st V20 to get onto the Feb Sec. Patch, all other carriers are still on Dec or older. But the update came for the sprint V20, and within 30days of it being live, weve managed to get the ota pushed to our rooted users and its working GREAT!

I can say 1 thing for sure, if you update your V20 to zv6 without being rooted 1st this debate is over anyways as it wont/cant be rooted anymore and the decision is gone to do so. But otherwise, theres a reason youve landed on xda, wondering about what the hype is about rooting etc, ill just leave a screenshot of my device here for looks. Im very proud of the work myself and the rest of the community has done. The device runs 10x faster and longer then the OEM;s software the released, and so many little bugs etc have been fixed also on our end to enhance it further. With the countless options to theme, customize and change ur device, the learning and experience itself is $$.

Ultimately, i vote to root the $H!T out of your phone, and worst case, get it replaced and do it again if you F it up!
