8 Best Android Apps To Improve Privacy and Security in 2015

As Mobile Device Security is comprised of security of different features, such as:

• Data privacy and security features
• Permission restrictions for snoopy apps
• A blacklist for undesired calls
• An excellent backup capability, in case your smartphone gets deteriorated.
• As well as encryption functionality.

Google’s Android is a very flexible mobile operating system that can fulfill all these mobile device security challenges if you select the right security applications from Google Play Store.

No doubt, Google Play Store has an abundance of suitable options, and it’s quite difficult for you to select the ones that meet all your expectations.

So, I decided to help you by making a short list of the best mobile device security applications that I always carry in my Android smartphone.

Here are the best security apps you must have in your Android smartphone; have a look:

TextSecure Private Messenger (Free)

There are vast number of secure messaging apps available in Play Store, but the trouble part is that most of them work only if both the parties use the same application for encryption to work.

TextSecure breaks that barrier and works with standard SMS text messages as well, which means you can add an extra layer of security to regular texting even if the client you are messaging is not using TextSecure.

TextSecure Private Messenger is a free secure text messaging app developed by Open Whisper Systems. It is completely open-source and supports end-to-end encryption for secure text messages, means nothing is stored on its server.

Your private conversations will be even safer if both parties are chatting directly through the TextSecure app, but the ability to encrypt your standard SMS messages makes it different from other secure messaging apps.

Download & Install TextSecure Private Messenger.

RedPhone: Private Calls (Free)

RedPhone is a free secure call app that provides end-to-end encryption for your private calls, securing your phone conversations in a way that nobody can listen in.

The purpose for which I use the Red Phone app is that it’s very easy to use. Red phone uses your standard phone number to make and receive phone calls, so there is no need for any other identifier.

The Red phone app, created by Open Whisper Systems, is completely open source and free to download from Google Play Store.

AppLock (Free Application Lock Utility)

AppLock is used to protect your personal data to be accessed by anyone. You can put lock to your SMS, Contacts, Gallery, Gmail, Settings, Facebook, Calls and any other app you want to keep away from outsiders.

Do not confuse AppLock with your phone in-built lock feature, as the in-built feature of your smartphone only allows you to put lock on your phone, but not on the selected apps you want.

With AppLock, you don’t need to worry about a friend borrow your phone to play games again or they get your smartphone to have a look. Your private data in certain apps is secured by the app, protecting your privacy.

App Ops (Free App Permission Manager)

App Ops is an Android app that allows you to block permissions to individual apps. This is a great app that allow me to block unnecessary app permissions of certain apps that do not have anything to do with the main function of the apps.

Generally, Android OS is built with an in-built app permission system and when you install any app from Play Store you are asked to grant the permissions that the app requests. If you decline to agree, the app is not installed. It’s an all or nothing situation.

App Ops solves this issue and allows you to change the app permissions. So if, for example, you don’t want your flashlight app to collect your location-based data, which is being used by ad agencies, then you can revoke that permission for that particular app.

App Ops is available for free in Google Play Store and supports Android 5.0.

However, App Ops is still accessible on Android 4.3, 4.4.0 or 4.4.1 if your device is rooted. If you have upgraded your Smartphone to Android 4.4.2 then you need to first launch a root authentication and then reboot your device.
