Screen and design

The differences between the devices start with the screen. The Galaxy S21 Plus comes with a 6.7″ display, which should please anyone who likes screens. Samsung’s AMOLED Dynamic 2X technology promises to help save energy and leave the phone with a faster response rate. Full HD+ resolution (2400 x 1080 pixels) has a density of 394 PPI, and a 120 Hz screen refresh rate helps to make scrolling and viewing smoother.

The device also features Eye Comfort Shield, which automatically adjusts the blue light filter based on the time of day, which promises to reduce eye fatigue, and HDR10+ certification, which promises the same image quality as Dolby Vision.

The iPhone 12 Pro has a 6.1-inch screen with OLED technology, also known as Super Retina XDR Display, which promises more brightness and deeper contrast. The device has Full HD+ resolution (2532 x 1170 pixels) with 460 PPI, which should provide higher resolution images compared to the Samsung cell phone. The True Tone option also helps to display more natural colors, according to the ambient light.

In terms of design, the Apple smartphone has become more similar to the iPhone 4 and iPhone 5 design. The device is 11% thinner, 15% smaller in volume, and 16% lighter than the iPhone 11. The display has Ceramic Shield for protection. The technology consists of a mixture of materials that form the front glass, and a surgical grade stainless steel body. The company ensures that the durability is up to four times higher than previous models.

iPhone 12 Pro

The Galaxy S21 Plus uses the Gorilla Glass Victus to preserve the display from drops and scratches. The front camera is housed inside the display, unlike Apple, which still keeps the notch. Both come with IP68 protection, which allows the phone to be submerged up to 1.5 meters for up to 30 minutes. However, Apple promises resistance to dives of up to six meters.

The iPhone 12 Pro comes in silver, graphite, gold, and blue, while the Galaxy S21 Plus can be purchased in white, gray, violet, and pink.


Regarding the camera, both come with a triple set. Samsung’s device has optical zoom up to 3X, digital zoom up to 30X, and an ultra-wide camera that captures 120° field of view (even from human view). The set is divided as follows:

  • Ultra-wide 12 MP and 120° (f/2.2)
  • 12 MP (f/1.8) main (wide)
  • 64 MP Telephoto (f/2.0)
  • 10 MP Front (f/2.2)
Galaxy S21 Plus

The iPhone 12 Pro also has an ultra-wide camera with 120° field of view, up to 4X optical zoom, and up to 10X digital zoom. Apple guarantees that the wide camera sensor is 47 percent larger than the previous version, but does not specify the size. The lens also comes with a LiDAR sensor, which improves the depth of field perception in augmented reality (AR) – the same seen on the iPad Pro. The camera looks like this:

  • Ultra-wide 12 MP (f/2.4)
  • 12 MP wide-angle (f/1.6)
  • 12 MP Telephoto (f/2.0)
  • 12 MP Front (f/2.2)

Regarding the video, the iPhone 12 Pro records in 4K at a speed of 60 fps (frames per second), while the Samsung model allows records in 8K at 30 fps. Both record in 4K on the front camera.

Performance and storage


Super powerful processors are present in both models. The iPhone 12 comes with the recently launched A14 Bionic chipset (hexa-core up to 2.65 GHz), which promises speed 50% higher than the other cutting-edge smartphones with an Android system. Apple does not officially disclose the amount of RAM, but specialized sites report that the device features 6 GB.

On the other hand, the Galaxy S21 Plus processor is the Snapdragon 888, from Qualcomm, will be present in some countries, such as the United States. And another version with Exynos 2100, an octa-core of up to 2.9 GHz that works together with 8 GB RAM, the model will be sold in country like Brazil. The processor of the two smartphones is 5 nanometers, which translates into smaller internal components, greater energy efficiency, and battery savings.
