"Smart deactivation of your device screen saver"

Reviewed by / Sep 04, 2012

SmartStay EX uses front camera to detect when you're looking at the phone and keeps screen on

Imagine this situation, you set your screen off timeout in just a few seconds in order to extend battery life. However, that's annoying when you're actually looking at your device (for example, when you're reading on it). Since it would be annoying changing screen timeout all the time, the guys from nebkat have developed an app that solve this issue, adding a new feature that's only available in the latest devices like Galaxy S3.

Smart Stay uses front facing camera to detect when you're looking at the phone. Then, makes sure the phone screen stays on. When you stop looking at it, you preferred timeout will be applied as usual. Save battery but don't make that disturb you thanks to this app.

A great tool for those who use to read in their device. Recommendable.

Developer's original description available here
SmartStay Ex keeps your screen from turning off while you are using it.

SmartStay Ex scans the front camera for faces at regular intervals. If a face is found, it will keep the screen from turning off. There are many advanced options available and many more planned!


- Supports Android 2.3+
- Customizable check frequency
- SmartTimeout™ - Only scan when screen is about to turn off
- [PRO] Optional status bar notifications
- [PRO] Optional customizable vibration notifications
- [PRO] Continuous mode - scan for a few seconds rather than taking a single picture
- [PRO] Low light mode
- [PRO] Exception list - don't scan in chosen apps (e.g. app that lags while scanning)


Q: Does SmartStay Ex waste battery?
A: SmartStay Ex wastes very little battery, especially when vibration notifications are disabled.

Q: Does SmartStay Ex only work if it recognises my own face?
A: SmartStay Ex does not recognise faces, it just detects them, so it will work with any face.

Q: Do camera apps work when SmartStay Ex is enabled?
A: Yes, but occasionally there could be a few second delay if SmartStay Ex is scanning.

    As mentioned by other people, when this app is running, and you open the camera, it will freeze and result in the phone rebooting. It is an option to have it turned off when using the camera but only if you buy the paid version. So basically if you want it to work, you have to pay for it. Edit: I can't do it anymore. App has a lot of potential, and it does work as it should, but since it ma
