Finger gestures

Tap

When you want to type using the keyboard, select items onscreen such as application and settings icons, or press onscreen buttons, simply tap them with your finger.

Press and hold

To open the available options for an item (e.g. contact or link in a web page), simply press and hold the item.

Swipe or slide

To swipe or slide means to quickly drag your finger vertically or horizontally across the screen or optical trackball.

Drag

Press and hold your finger with some pressure before you start to drag. While dragging, do not release your finger until you have reached the target position.

Flick

Flicking the screen is similar to swiping, except that you need to swipe your finger in light, quicker strokes. This finger gesture is always in a vertical direction, such as when flicking the contacts or message list.

Rotate

For most screens, you can automatically change the screen orientation from portrait to landscape by turning the phone sideways. When entering text, you can turn the phone sideways to bring up a bigger keyboard. Refer to the Settings chapter for more details.

Pinch

For some applications, like Photos or the web browser, you can “pinch” the screen using 2 fingers (for example, thumb and index fingers) to zoom in or zoom out when viewing a picture or a web page.

Aria specifications

The HTC Aria, released in June 2010, was a compact smartphone that marked HTC's entry into the mid-range Android market. Its sleek design and feature set made it an appealing choice for users looking for a balance between functionality and portability.

One of the standout features of the HTC Aria was its 3.2-inch capacitive touchscreen display, which offered a resolution of 240 x 320 pixels. Though not groundbreaking by today’s standards, the screen provided vibrant colors and reasonable responsiveness for its time, enhancing the overall user experience. The Aria’s design was characterized by its lightweight and compact form, making it easy to hold and operate with one hand.

Under the hood, the Aria was powered by a Qualcomm MSM7227 processor running at 600 MHz, paired with 384 MB of RAM. This setup allowed for smooth navigation through Android 2.1 Eclair, the operating system it initially shipped with. HTC's Sense UI overlay provided a visually appealing and user-friendly interface, adding widgets and customizable home screens that enhanced user interaction.

The device featured a 5-megapixel rear camera capable of capturing decent photos, a notable inclusion for a smartphone at its price point. It lacked a front-facing camera, which was not uncommon at the time, but the rear camera did support features like autofocus and LED flash.

In terms of connectivity, the HTC Aria supported 3G, Wi-Fi, and Bluetooth 2.1, ensuring users could easily access the internet and connect to other devices. The inclusion of GPS further enriched the user experience, allowing for improved navigation and location-based services.

With a modest internal storage of 512 MB, the Aria also supported microSD cards, enabling users to expand their storage capacity significantly. The device came with a 1200 mAh battery, which provided a reasonable battery life, balancing performance and longevity for daily use.

Overall, the HTC Aria served as a bridge for users entering the smartphone world. Its blend of practical features, a customizable interface, and a compact design made it a solid choice for those seeking a user-friendly Android device without the complexity or expense of high-end smartphones.
