Galaxy S21 Ultra vs. iPhone 12 Pro Max: Design

The Samsung Galaxy S21 Ultra’s unique contour cut camera design blends the camera into the glass back. Although the Ultra has a slim look, it is nevertheless a powerful phone. It measures 6.33 x 3.07 x 0.29 inches and weighs 8.03 ounces, while the iPhone 12 Pro Max measures 6.5 x 2.97 x 0.35 inches and weighs 8.08 ounces.

I also prefer the iPhone 12 Pro Max’s flat edges to the Galaxy S21 Ultra’s curved sides.

The iPhone 12 Pro Max has an edge in terms of durability and water resistance. The Ceramic Shield display of the iPhone is meant to resist four times more drops than its predecessor, and it has shown to be successful in drop tests. The phone’s Gorilla Glass Victus screen makes no such guarantees, according to Samsung.

The IP68 water resistance rating of the iPhone 12 Pro Max is up to 6 meters, compared to 1.5 meters for the Galaxy S21 Ultra. The iPhone 12 Pro Max’s primary fault is the display notch; the S21 Ultra has a little punch hole camera on the front.

The 12-megapixel primary camera, 12-megapixel ultra-wide camera, and 12-megapixel telephoto zoom lens with 2.5x optical zoom are all included in the iPhone 12 Pro Max. A LiDAR sensor is also integrated, which helps with portraiture and low-light photography.
The cameras on both the S21 Ultra and the iPhone 12 Pro Max are superb, but they excel in different ways. The S21 Ultra wins hands clear in zoom capabilities because its lenses just go further.

Galaxy S21 Ultra vs. iPhone 12 Pro Max: Software and special features

The iPhone 12 Pro Max receives a slew of new features with iOS 14, including widgets on the home screen for quick access to information and a Smart Stack with many widgets in one place. Additionally, the new App Library feature automatically groups your apps by category.
Apple’s messaging software also includes a number of useful features, such as pinned conversations and inline responses. iOS 14 also has a more streamlined appearance, with a smaller Siri and calls UI that remains out of the way. The spatial audio function in AirPods Pro provides you a 360-degree sound experience.

The Galaxy S21 Ultra runs One UI 3.0 on top of Android 11 and has its own set of features. This contains a large number of widgets that may be accessed without having to unlock your phone. The Quick Panel can now be customized to get things done faster, and there are new camera gimmicks like Director’s View, which allows you to shoot video with both the front and back cameras at the same time.
The support for the S Pen, however, is a one-of-a-kind feature. The S21 Ultra’s display features a digitizer that accepts S Pen input. For $69.00, you can get a silicone case with a S Pen. Based on my tests, the S Pen performs admirably, making it ideal for taking notes and drawing, although it lacks Bluetooth connectivity.
