I've been trying to read reviews but I can't seem to get a difinative conclusion. Does anyone one here have opinions?
Here's my opinion:
G7:
• Brighter "Ultra Bright Mode" display
• IPS LCD screen will never get screen burn-in
• Much louder "BoomBox" sound chamber
• Better battery life? Snapdragon 845 vs. 835 plus the new MLCD+ technology supposed to help save battery (battery is smaller by 300mAh though it doesn't necessarily mean it's weaker) according to LG engineer
• Apparently the screen is FLATTER and installing a tempered glass screen protector is possible and not an issue
• Extra button for Google Assistant
• Bezelless display with a notch (good or bad depending on your preference, however you can turn it off)
• Just a tad smaller in size, barely smaller
• Newer and improved cameras, you get two 16MP lenses.. however seems like LG reduced the POV of the wide angle on the G7 to reduce distortion...
• Much better 8MP front facing camera (compared to 5MP)
• More expensive than the older V30 (but still affordable)
• Slightly updated and improved Quad DAC
• Headphone jack is on the bottom again (better IMO)
V30:
• P-OLED display (subjectively looks more beautiful especially black colors, however subject to permanent screen burn-in and doesn't age well)
• Slightly larger battery by 300mAh (but possibly weaker battery due to older CPU plus the more power hungry OLED screen)
• No notch, better looking design and more curved body (Subjective)
• Curved screen more pronounced therefore installing a tempered glass screen protector has been a big issue among users.. the only ones that work good are the expensive ones which require expensive equipment to install..
• More affordable (especially used) since it's been out for a while, probably half or a third of a cost of a G7.
• 16MP + 13MP wide angle lens
• Very weak 5MP front facing camera (lower quality image than the V20 IMO) however I think the selfie camera is more wider than the G7 but I'm not sure about that
• No extra Google Assistant button, no BoomBox sound chamber, no notch, older version Quad DAC, no ultra bright mode.
Overall, the G7 has newer tech, has a slightly smaller body (barely), has an MLCD+ display as opposed to P-OLED, has a BoomBox sound chamber, much better 8MP selfie camera, a 16MP wide angle versus 13MP, most likely costs 1.5x - 2x more since it's newer, has a notch, and most importantly the screen is FLATTER so installing a glass screen protector is easier.
If money is not an issue, if you don't mind the notch, if you don't mind LCD, if you want newer tech, and if you don't mind paying more, get the G7.
If you like AMOLED, if you hate the notch, if you want to save money, get the V30.
