10 Tricks to Make Yourself a WhatsApp Master

Smart Phones are no longer a simple handset by which we can call someone or can send text messages to someone; rather it is an accumulation of handset, digital diary, bridge to the internet, entertainment source etc. For many purposes, we have installed so many applications on our smartphone that we cannot even remember them until we are in real need of them. Some of those applications are so useful and confidential that we need real security to protect them from unwanted entry and un-authorized un-installation. For this kind of annoyance, first thing comes to my mind is AppLock app.


More and more of us are increasingly dependent on our smartphones for running many aspects of our lives. One drawback with this is the amount of personal and financial information we have stored on our mobile devices. This ranges from social media, messaging apps, or the photos and videos from the gallery, to banking apps where sensitive financial information might be at risk. Many people are understandably concerned about the dangers posed by prying eyes, so it’s a good idea to ensure the privacy on your smartphone with a security app. This is extremely important, today more than ever, and fortunately, it’s fairly simple to do.


One way of securing your private details is with the use of an app lock, and some device owners choosing to use a custom ROM might already be taking advantage of a built-in app locker. However, most device users don’t use custom ROMs, but the good news is that there are many App Locker apps available on the Google Play Store that will help to protect your apps and keep such information safe from snoopers. They can work in a variety of ways to lock your apps, including through a fingerprint scanner, password, or PIN.
