LG will be announcing its second flagship smartphone of 2017 on 31 August in Berlin. The smartphone will come in the form of the LG V30, succeeding the V20 that launched in September last year.

Although in the past the V series hasn't been made available globally, it sounds like the V30 will be so how does it compare to last year's model? We have put the rumoured specs of the LG V30 up against the LG V20 to see what the differences are, based on the speculation.

  • LG V30 expected to be waterproof
  • LG V30 rumoured to be smaller in footprint
  • Both expected to be MIL-STD-810G compliant

The LG V20 features a lovely lightweight premium build with super slim bezels surrounding the display. On the back, there is a dual-lens camera setup with a flash to the left, along with a circular fingerprint scanner beneath the camera module. Branding is kept to a minimum with a small LG logo at the bottom of the display and a V20 logo at the bottom of the rear.

It measures 159.7 x 78.1 x 7.6mm and hits the scales at 176g. LG made the V20 MIL-STD-810G compliant in order to better resist shock and impact, but there is no waterproofing on board. The LG V20 features USB Type-C and a 3.5mm headphone jack.

The LG V30 is rumoured to be continuing with the premium design standard set by the V20 and G6, though rather than aluminium like the V20, it looks like it might have a glass rear like the G6. A dual-rear camera setup is confirmed, though based on the leaks it looks like the flash will be positioned inbetween the lenses this time round, and a circular fingerprint sensor is expected beneath the camera module again.

According to the rumours, the V30 will measure 151.4 x 75.2 x 7.4mm, making it smaller than the V20 if true. No weight leaks have appeared as yet. The front will offer an almost all-screen front though, moving the LG logo to the bottom of the rear, while the V30 logo appears to be positioned in the centre. USB Type-C and a 3.5mm headphone jack are expected again, along with IP68 waterproofing and MIL-STD-810G compliancy.

  • LG V30 will have a larger display 
  • LG V30 will have OLED over LCD
  • LG V30 will have 18:9 aspect ratio over 16:9

The LG V20 features a 5.7-inch display with a Quad HD resolution that puts its pixel density at 513ppi. It's an IPS LCD display and it is protected by Corning Gorilla Glass 4. There is also a 2.1-inch secondary display with a 1040 x 160 pixel resolution at the top of the main display, allowing for access to various notifications and information.

The LG V30 is confirmed to be coming with a 6-inch OLED display, making it the first LG device to offer an OLED panel aside from the flexible G Flex smartphone. The 6-inch display will have a 2880 x 1440 pixel resolution, resulting in a pixel density of 537ppi, making it sharper and crisper than the V20 by a fraction and a secondary display will be present again but in the form of a 'Floating Bar' that can be swiped away when not required, rather than a fixed bar at the top of the display.

As you might recall, the V30 is rumoured to be smaller in footprint than the V20 despite offering a larger display. This is likely down to the change in aspect ratio. The V30 will offer LG's FullVision display with a 18:9 aspect ratio, as found on the LG G6. It will also likely come with Dolby Vision and HDR 10, making it better equipped for entertainment over its predecessor.

  • V30 will have wider aperture
  • Both have dual-rear cameras
  • Potentially higher resolution front camera on V30

The LG V20 placed a big focus on camera and video capture, as well as audio, being the first smartphone when it launched to include a 32-bit Quad DAC from ESS and feature ESS's HyperStream 2 audio technology. It has a dual-rear camera with one 16-megapixel sensor offering an f/1.8 aperture and an 8-megapixel sensor with a f/2.4 aperture.

Laser autofocus, optical image stabilisation and an LED flash are all on board, while the front snapper is 5-megapixels with an aperture of f/1.9.

The LG V30 will come with a dual-rear camera too, as confirmed by LG, though the resolutions for the rear and front cameras have yet to be detailed. It could be that it will be the same as the G6 with two 13-megapixel lenses on the rear and an 8-megapixel lens on the front but we don't know at the moment.

LG has however also confirmed the rear camera will offer an aperture of f/1.6, which would apparently allow for 25 per cent more light than a f/1.8 lens, like the V20 and G6. The company said we can expect laser detection autofocus, optical image stabilisation and electronic image stabilisation on the V30, along with facial recognition from the front snapper. We're also expecting a focus on audio capture too, like the V20.

  • Faster more capable processor likely on V30
  • USB Type-C and Quick Charge on both likley
  • V30 could have more RAM

The LG V20 comes with the Qualcomm Snapdragon 820 chipset, coupled with 4GB of RAM and a choice of 32GB or 64GB of internal storage. There is microSD on board for storage expansion and the V20 has a 3200mAh battery capacity.

Qualcomm's Quick Charge 3.0 is supported and USB Type-C is present for charging on the V20.

The LG V30 is rumoured to be coming with the Qualcomm Snapdragon 835 platform, which should mean it is faster and more capable than the V20. RAM and storage capacities have yet to be rumoured, but we would expect at least 4GB of RAM and 32GB internal storage, with microSD support.

There is no word on battery capacity as yet either, but we would guess it will be around the same as the V20 or G6, putting it in the 3200mAh to 3300mAh mark. USB Type-C will no doubt be on board again and Quick Charge is also bound to be supported.

  • Both Android with LG's UX software
  • V30 will have some extra features

The LG V20 launched on Android Marshmallow with LG's UX 5.0 software over the top, while the LG V30 will launch on Android Nougat with LG's UX 6.0+ software on top.

The software experience will no doubt be similar between these two models but there will be a few additional features to arrive with the V30, including enhanced security measures, functions that take advantage of the new display and a new camera feature called Graphy that will be found within the manual camera mode.

Based on the rumours, the LG V30 will feature a premium design like the V20 but with a few tweaks here and there. It will also definitely come with a larger display, higher resolution, a wider aperture rear camera, enhanced software and a different form of secondary display.

Everything else is guesswork for now, but we'd expect to see a more advanced processor, more RAM and more camera improvements in the V30 over the V20. The V20 was a powerhouse of a phone so no doubt the V30 will be too.

We will update this feature as we find out more.
