If you fear that your privacy may be compromised by not having your phone sufficiently protected, you may want to consider a blocking app to ensure access to your device. Maybe Screen Lock: Time Password is what you're looking for.
Protect your Android with PIN, pattern or password
It is not superfluous to add a layer of security to the one Android already has. This app will allow you to do so, by setting a PIN, pattern or password to access it. You can also use it in specific applications, such as your social networks, your messaging apps or your photo gallery. It is a very easy to use app that offers the following functions:
- iPhone style lock screen.
- Customizable lock screen.
- Unlocking sound.
- Possibility to set a blocking PIN according to the current time dialed by the device.
- Configure access passwords.
What happens is that, we must say, it is not the best blocking app: too much advertising and a little confusing interface in some aspects. Maybe you prefer other options you can find in Malavida, such as AppLock, Norton App Lock or Smart AppLock.
