Giữ Sáng Màn Hình - Keep Screen is a free Android app developed by Phạm Văn Tú 1998 in the Utilities & Tools category. This app makes sure that your device's screen always stays on and does not turn off automatically. The latest version, 3.0, has updated all the necessary features for your phone to always keep the best lighting.

One of the main features of this app is that it allows you to quickly turn on and off the screen. When charging, the app will connect to the device to brighten the screen, and when it's fully charged, it will automatically turn off the application. This feature protects your battery from damage and overheating. Additionally, it integrates the minimum lighting of your phone, which helps you read news, watch movies, and play games with ease.
