How to lock incoming and outgoing calls on Android phones?

Are you worrying about others around you will see the number or name of the person who is calling you? As our screen lock can’t hide the name or number of caller for your incoming calls. Do you want to prevent others from answering incoming calls or making phone calls when you let them use your phone for other purposes? In this article, we will use a free Android phone privacy and security app that can lock incoming calls and outgoing calls behind a password or pattern. Without unlocking them first, no one can make phone calls or take incoming calls even if they can unlock your phone screen.

Important Tips: App lockers can be a double-edged sword. On one hand, they can provide an additional layer of security and privacy for users by preventing unauthorized access to sensitive apps and data. On the other hand, app lockers can also have negative effects. For example, they can sometimes cause technical issues, like slowing down your device, causing apps to crash, creating a false sense of security, reducing productivity. When the pattern or password is too complex or you use multiple passwords for different systems, it can be tedious and frustrating in remembering and entering them. What’s worse, you may lock yourself out of your phone or data when you lost and can’t reset these passwords or patterns.

AppLock is the security and privacy protection app you will need. You can find more details and download it below.
