When you get an Android phone you should always use the application lock feature to keep your phone safe and secure. If your phone goes missing you will be able to find it because the phone will lock up so that you can't get into it and even if you get in it, you will not be able to change the software on it. The best way to unlock your phone is to download the free AppLock app and then have it lock your phone when you are not on it. This way you can still use your phone while you are traveling or if you are on the go you can get in and out of your phone just as you normally would.
The download for this application is free and easy to use. You just download it onto your phone and then install it on your phone. Once you have installed the app, you will have the option to select a password for your phone. After that you will be able to turn the lock on and then it will scan through your phone to make sure that it knows that you are the owner of the phone and that you are the only one that can use it. This will allow your phone to lock up so you can't get into it and then you can download the free application again and you will be able to use your phone. The free version can be downloaded at the Google Play Store for free and then you will be able to unlock your phone as you would normally with the free version.
