The V30 doesn't feature a removable battery or a secondary display like its predecessor, but it does have better performance and a significantly redesigned build construction that puts in more in line with Samsung and Apple's offerings.
It is basically a bigger device with better specs which looks a lot like the G series. LG got rid of the secondary display in favour of a single 6-inch LG P-OLED display. It is not Super AMOLED, although it is similar enough for most users not to spot the difference.
The V30 switches out its secondary display for slimmer bezels. The specs are good but not as good as the rumoured 6GB of RAM rather than 4GB. The V30 features sophisticated audio and a dual rear camera set-up. It has a rear fingerprint sensor, which has been problematic for Samsung this year with the S8 and the Note 8.
The LG V30 is set to release on September 21 in South Korea, with releases in North America, Asia, Africa, and Europe following shortly after. LG also has yet to announce a price for the V30, although rumors peg it to be around 800,000 KRW in South Korea - which equates to about $699 in the US.
GSMArena has a full spec sheet available for the LG V30. Some of the noteworthy specs include a 6-inch LG P-OLED display with an 18:9 aspect ratio and QHD (1440 x 2880) resolution, Snapdragon 835 processor with 4GB RAM, dual 16-megapixel/13-megapixel rear-facing camera sensors, headphone jack, 32-bit/192kHz audio, wireless charging and Android 7.1.2 Nougat.
