For starters, LG's next flagship will probably use an OLED screen.

At the Google I/O 2017 keynote presentation, Google let slip (well, it was surely intentional) an important clue about an unannounced Android phone. In addition to confirming that the Galaxy S8 and S8+ will get Daydream support via a software update later this year, Google's Clay Bavor told attendees that LG's next flagship phone would also be Daydream ready.

Since we've already seen the flagship LG G6 this year, that sure sounds a lot like the LG V20's successor.

LG V30 rumors

What's interesting about this proclamation about Daydream support is that the spec currently requires an AMOLED display, because LCDs have so far lacked the super-low latency required for a smooth, comfortable VR experience. This would be a first for LG, which has in the past relied exclusively on IPS LCD panels in its top-end devices. So either there's been some breakthrough in LCD panel latency we don't yet know about, or (more likely) the LG V30 will go with OLED, which has a proven track record in both VR headsets and VR-enabled phones.

AMOLED has a proven track record in both VR headsets and VR-enabled phones.

LG has invested billions in OLED production over the past year, and has previously dabbled in using flexible OLED with the G Flex series. LG Display division has also been rumored to be supplying panels for both the next-gen iPhone and Google's upcoming Pixel 2 phones. The time might be right, then, for LG's mobile division to consider OLED for its next big-screened handset — a phone which would likely go up against Samsung's Galaxy Note 8.

As for other LG V30 features, all we have to go on at this point is (somewhat) informed speculation. A large screen size is a good bet, as is a G6-like 18:9 aspect ratio. It's also likely LG would launch its own Daydream headset with the V30, whichever display technology it ends up using, rather than send potential sales to Google or some other headset maker. We'd also bet on a Snapdragon 835 and a significant RAM upgrade, giving the V30 an edge on the G6, and bringing LG's top-end handset in line with Samsung, HTC, OnePlus and others.

Whatever form the V30 takes when it eventually materializes, Google's announcement offers a rare early clue as to what's coming. Stay tuned in the months ahead for more V30 info as it lands.
