Cameras

The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.

The number of megapixels determines the resolution of the images captured with the front camera. A higher megapixel count means that the front camera is capable of capturing more details, an essential factor for taking high-resolution selfies.

Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.

The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.

With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.

A dual-tone flash has LED lights with different color temperatures, delivering a better color balance to photos and videos.

A BSI (backside illuminated) sensor is a camera image sensor which captures better quality images in poor lighting conditions, and offers better overall sharpness and image quality.

When recording movies they stay focussed and sharp.

Phase-detection autofocus is much faster than a contrast detection autofocus, allowing for sharper images.

Operating system

This privacy feature alerts you with a small notification when an app copies data from your clipboard.

This privacy feature allows you to share your approximate location with an app instead of your precise location.

You can enable or disable an app’s access to the camera or microphone on your device. There are also indication icons to show you when an app uses the camera or microphone.

Mail Privacy Protection is a feature built into the default email app that blocks senders from using “tracking pixels” to see when you’ve read an email. It also hides your IP address from senders.

Theme customization allows you to easily change the appearance of the user interface (UI). For example, by changing the system colors or the app icons.

Some apps track your activity even when the app is not in use. This privacy feature allows you to block this tracking, either across all apps or on a per-app basis.

This setting (in the default browser) allows you to block cross-site tracking cookies and data to help protect your privacy.

On-device machine learning is used to recognize people, places, and more in the Photos app. The algorithms run on the device, where this sensitive data is then kept. Competing services upload the photos and perform this on their servers, which requires the sharing of personal data.

This means you don’t have to wait for the entire game to download first, as the later stages of the game download while you are playing.
