Stop your phone from turning off.

Keep Screen On is a free browser tool that keeps your Android screen on and prevents it from turning off while this page remains open. Choose a time limit or No Limit, press Start, and keep your Android display awake without changing screen timeout or other device settings.

The tool uses the Screen Wake Lock feature supported by Chrome and other modern browsers on Android to prevent screen dimming, screen sleep, and automatic locking while the timer is running. It does not change your Android settings, and there is nothing to download or install from the Play Store.

It works on Android phones and tablets in Chrome, Samsung Internet, and other supported browsers. Whether you need to keep your Android display on for a few minutes or keep your device awake for hours, you can start the timer and let it run until you're finished.

The most common reason to keep your Android screen on is to stay marked as online or active in work apps, messaging platforms, remote desktop sessions, and social media without your phone entering sleep mode or locking while you're away.

It is also useful while downloads, uploads, backups, updates, and other long-running tasks are in progress on your Android device. Keeping your display awake helps prevent screen timeout, screen dimming, and interruptions caused by sleep mode.

You can also use it whenever you want to keep your Android display on, avoid repeated PIN or fingerprint prompts, prevent screen sleep during presentations, or simply stop your phone from sleeping for a while without changing your normal screen timeout settings.
