Keep Your Phone & Calls Private with These 2 Powerful Android Apps 2025

Sure! Here’s the English translation of your message:
Greetings dear brothers and sisters.
Today’s lesson is about some mobile applications that can help you hide your privacy, ensuring no one can access your phone, your call screen, or even your phone’s password without your permission.
We’ll talk about two applications, both very useful — I’ll list them below.
1️⃣
First Application: Dynamic Password Based on Time
This app allows you to set a password that changes every minute or hour, based on your phone’s clock.
Normally, when you set a static password, it can easily be guessed or seen by someone — and then your phone is no longer secure. That’s why people keep changing passwords frequently.
But don’t worry — here’s a solution:
This app lets you set a password that matches the current time on your phone.
For example:
- If the current time is 11:06, your phone’s screen will unlock only if you enter 1106.
- If the time becomes 12:07, the password also becomes 1207.
So, the password keeps changing every minute, and you must use the current time digits to unlock your phone.

2️⃣
Second Application: Call Screen Security App

This app allows you to add security to your incoming calls.
So anytime someone tries to answer a call on your phone, they will be required to enter a password first.
Why is this helpful?
Because sometimes, when you’re not around and someone calls you, someone else might pick up your phone and answer the call — even use your phone without your consent.
But with this app:
- You can choose specific people whose calls require a password before answering.
- Or you can choose to require a password for all incoming calls.
- You can even set different levels of security for different contacts.
This app is also very useful for protecting your privacy.
