Feature-by-Feature Breakdown

Display

  • G7: Features a 6.1-inch IPS LCD display with a 1440 x 3120 resolution and a 19.5:9 aspect ratio. It offers excellent color accuracy and brightness, making it great for outdoor use. However, as an LCD, it doesn’t achieve the absolute blacks and contrast of AMOLED.

The AMOLED panel provides vibrant colors, deep blacks, and excellent contrast, leading to a more immersive viewing experience. Some users might find the slightly taller aspect ratio less ideal for certain content.
  • Winner: s9 plus

Processor & Performance

  • G7: Powered by the Qualcomm Snapdragon 845 processor, paired with 4GB of RAM. This chip delivered flagship performance at its release, handling most apps and games smoothly. While still capable, it’s a generation behind the S9 Plus’s chipset.
  • S9 Plus: Equipped with the Qualcomm Snapdragon 845 (US) or Exynos 9810 (international) processor, with 6GB of RAM. These processors were top-tier for their time, offering robust performance for demanding tasks and multitasking. The extra RAM on the S9 Plus provides a slight edge in sustained multitasking.
  • Winner: s9 plus

Camera System

  • G7: Features a dual-camera setup: a 16MP main sensor and a 16MP ultrawide sensor. The ultrawide lens is a standout feature, offering unique perspectives. Image processing can sometimes be a bit aggressive, leading to slightly unnatural-looking photos in certain conditions.
  • S9 Plus: Comes with a dual-camera system: a 12MP main sensor with variable aperture and a 12MP telephoto sensor. The variable aperture allows for better low-light performance and depth-of-field control. It generally produces excellent, well-balanced photos with good detail and dynamic range.
  • Winner: s9 plus

Battery Life

  • G7: Houses a 3000 mAh battery. While sufficient for moderate use, heavy users might find themselves needing a midday charge. It supports fast charging, which helps to mitigate this somewhat.
  • S9 Plus: Equipped with a 3500 mAh battery. This offers a slightly better endurance than the G7, especially for moderate users. It also supports fast charging and wireless charging for added convenience.
  • Winner: s9 plus

Audio

  • G7: Features a “Boombox Speaker” which amplifies sound by using the phone’s body as a resonance chamber, offering surprisingly loud and full audio. It also retains the 3.5mm headphone jack. The audio quality is a significant strength.
  • S9 Plus: Includes stereo speakers tuned by AKG and supports Dolby Atmos for an immersive audio experience. It also features a 3.5mm headphone jack. The stereo setup provides a good, balanced sound profile.
  • Winner: g7

Design & Build

  • S9 Plus: Features a sleek glass and metal construction with curved edges. The design is refined and elegant, with a well-integrated fingerprint sensor on the back. It offers a premium in-hand feel, but the curved screen can sometimes lead to accidental touches.
  • Winner: s9 plus

Software & Updates

  • G7: Launched with Android 8.0 Oreo and received updates, but as an older device, it’s unlikely to receive further major OS updates. LG’s software is generally clean but can have some bloatware.
  • S9 Plus: Launched with Android 8.0 Oreo and received multiple major OS updates, reaching Android 10. Samsung’s One UI has evolved significantly, offering a feature-rich experience. However, Samsung’s update speed can be inconsistent.
  • Winner: s9 plus
