Create an illustration of a smartphone with a circular, magnetic attachment on the back. The phone screen should display a translation app interface with two language options (e.g., English and Spanish) at the top. Below, include a text input area labeled "Enter text for translation" and a "Translate" button. The app should have toggles for features like "Photo Translation," "Auto Voice Playback," and "Show Float Window." Ensure the attachment design is distinct, with a simple logo in the center, and alter the color scheme of the phone to a gradient. The overall aesthetic should be sleek and modern, reflecting a tech-savvy vibe.
