Screen Translation is a useful Android application developed by Vinasignage that allows you to translate game screens in real-time. The app runs in the background and floats on the screen, allowing you to drag it anywhere you want. You can choose between Google Translate or Microsoft Translate APIs to perform optical character recognition (OCR) and begin translating the text.

The app offers several features, including the ability to change the icon of Droidify, enable or disable sound, auto-detect language, select text on the screen, and set static or dynamic options for Droidify. Screen Translation also supports downloading the trained data file for OCR, saving translation history, and bookmarking. Additionally, users can chat with Droidify live and drag and select parts of the screen to translate.

One requirement to use the app is to allow it to start capturing the screen by checking "Don't show again" and clicking "START NOW" on the dialog when you begin translating the text on the screen. Overall, Screen Translation is a highly recommended app for anyone who wants to translate game screens in real-time.
