A comprehensive guide to the iPhone 7

The iPhone 7 was released in 2016 and runs iOS 15; it will no longer receive software updates. If an iPhone no longer receives software updates, it may still be usable for some tasks such as making calls, sending messages, browsing the internet, using apps that are compatible with its current operating system version, and playing media files. The iPhone 7 is water-resistant with an IP67 rating, which means it can withstand being submerged in water up to 1 meter deep for up to 30 minutes. However, it's important to note that water damage is not covered under the device's warranty, so it's still recommended to handle it with care around water. Other notable features of the iPhone 7 include a 4.7-inch Retina HD display with wide color gamut and 3D Touch, and a Touch ID fingerprint sensor for secure authentication. The iPhone 7 was the first iPhone to remove the traditional 3.5mm headphone jack and instead rely on a Lightning connector for audio.

More about the display

Retina display is a term coined by Apple to describe a high-resolution display that has pixels so small they are not visible to the human eye at a typical viewing distance. This type of display is used on many Apple devices, including the iPhone, and provides sharp and clear visuals. LCD (Liquid Crystal Display) is a type of display technology that uses a backlight to illuminate the screen. The backlight shines through a layer of liquid crystal cells to create images on the display. LCD displays are common on many smartphones and offer good color accuracy and brightness. OLED (Organic Light Emitting Diode) is a type of display technology that uses organic compounds to emit light when an electric current is applied. OLED displays do not require a backlight, which allows them to be thinner and more flexible than LCD displays. OLED displays are also known for their deep blacks, high contrast ratio, and vibrant colors. In summary, Retina display is a branding term used by Apple to describe a high-resolution display, while LCD and OLED are two different display technologies that are commonly used in smartphones. LCD displays use a backlight to illuminate the screen, while OLED displays do not require a backlight and use organic compounds to emit light.
