Lock Samsung phone Settings and apps

To protect our personal data on the phone, most of us would enable the screen locker so even if the phone is in wrong hands, our data is secured by the phone screen lock, could it be a pass code, PIN, pattern or fingerprint. Sometimes however the screen lock is not enough. For example, you may need to allow others, like your kids, coworkers, friends, to use your phone. In this case, how can you lock certain some apps, photos, or other data on the phone? In this article, we will use a Samsung Galaxy mobile phone to show you how you can lock Settings and certain or all apps on the phone. The instructions below also apply to other Android powered devices, such as LG, Nexus, Lenovo, Huawei, Xiaomi and more.

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.

Lock Settings and certain apps on Samsung mobile phone

Firstly you will need to download and use a security app as Samsung phone does not come with such a private data and app locker.

Secondly you need to determine which part of your phone or what kind of data you like to hide or lock from unauthorized access, such as photos, videos, files, chat history in WhatsApp, or else.

We recommend AppLock which is available for free download and use in Google Play and many other Android markets.

You will firstly need to set a pattern to lock the security app itself, then set a security question and answer, security email for lock pattern or PIN recovery.
