[LG V30 Questions & Answers] spexwood:
I upgraded from the V20 just 2 days ago and so far I'm LOVING my V30. I got my V20 after Samsung's Note7 disaster. I didn't want to downgrade to an S7 Edge, but the V20 still seemed like it was forced onto me. I liked the phone, but it was no Note7.

I will admit that the lack of Second Screen takes a bit of time to get used to if you integrated it into your daily usage patterns., but you probably won't miss it on the V30. The V30's Always On Display has a special "swipe bar" that has all the shortcuts that the V20's second screen had when the main screen was turned off (shortcuts like the wifi, bluetooth, camera, sound profile, etc toggles + music controller + shows icons for new texts, missed calls, etc). So that part is definitely similar and you most likely won't miss the Second Screen for that. The part that needs a little time to adjust to is the app shortcuts bar that appeared when the main screen was on. You will need to get used to the fact that all that info isn't in your face anymore, but will instead be on the hidden Floating Bar instead. You'll get used to it quickly though.

Admittedly, I don't use the Floating Bar on the V30. Too intrusive for me even though it's hidden. I just don't like that little half circle button on the edge of the screen. I instead use an app called Meteor Swipe, which adds a hidden swipe zone to the side of the screen (completely configurable from width, length, location, and left/right). When swiped out, you get app drawers (as many as you want) that contain as many apps as you want. It kind of mimics the S8 and Note8's side app drawer thingy. I used this on my V20 too since I really missed the side app drawers from my Note7.

I HIGHLY recommend upgrading if you want superb battery life compared to the V20's. This is why I actually upgraded. I'm a light user, with my phone mostly in my pocket all day, but about 1-2 hours of SOT. The V20 was needing a quick +30% charge to get me through the day (5am to 10pm). The V30 is lasting me all day with battery saver on (Set to Extended with only Restrict Background Data enabled and a few apps set to be excluded; Max brightness set to 100% in Battery Saver too, but auto-brightness is enabled) and some ATT and LG bloatware disabled. Yesterday (day off from work), I was using my phone from 9am to midnight and ended the day at roughly 85% with no charges and about 2 hours of SOT. I basically had my phone in my pocket all day, light texting, 2 short phone calls, and ended the night watching Youtube until I fell asleep. I fell asleep with my phone in my bed and woke up with only about 2% drain over night. Your battery life may vary obviously, and I'm only going off of memory, but DANG the battery life was remarkable!

EDIT: I should also note that even with Battery Saver on, I have yet to experience any lag or slow down. This phone is just super fast!

In short, you lose the V20's Second Screen, but gain so much more and keep several features of the V20 one way or another.

You gain:

-Faster CPU

-MUCH better battery life

-water proofing

-wireless charging (if you're into that... I personally could care less)

-battery saving tools not present on the V20's software

-lighter weight

-OLED screen that is really stunning (and saves battery over the V20's LCD display)

-And some other things I'm sure that I can't think of at the moment. The above mentioned were things I considered when deciding whether to upgrade or not.

You get to keep:

-The impressive DAC

-Main screen on Second Screen features are on the Floating Bar instead. Still there, but implemented differently.

-Main screen off Second Screen features are on the Always On Display instead. Again, still there, but different implementation.

-Impressive camera with all the manual settings... if you know how to use them... which I don't... soooooo....

Really, the only thing you lose is the toughness of the V20, but from what I've seen on Youtube drop tests, the V30 is still pretty strong.

EDIT: Oh, I should also mention that if you purchased themes for the V20 via the Google Play Store, they won't work on the V30 since it uses a different Home version than the V20. I was a bit disappointed by this at first since I love to theme my phones. The good news is that the same guys who made the V20 themes are working with the V30 now. Themes are currently scarce (at the time of writing this), but will populate the Play Store over the next several months.

Over all, I do recommend the V30 over the V20. Don't let the lack of Second Screen be a deciding factor for you.
