How to Encrypt Your Samsung Galaxy S 5
This is the most secure option for protecting your Samsung Galaxy S 5 phone. It’s an exceptionally secure option: It scrambles every file on your phone into gibberish, which it rapidly descrambles when you need the information. This sounds great; in practice, however, there are some important considerations to think about.
First, all this scrambling and descrambling takes processing power away from other things, such as running the apps. The loss is hardly noticeable in most cases — your phone is awash in processing power — but you never know when it might come back to bite you.
Next, after you encrypt your phone, you can never switch your phone back to non-encrypted use. With the Screen Lock options, you can use a PIN for a while, and then switch back to the pattern if you want. Not so with the encryption option. You will never, ever, ever, ever, get it back together.
If you encrypt your phone and then forget your password, your phone is bricked. In effect, its only future use would be in house construction as a brick; you won’t be able to use it as a smartphone anymore.
If you are sure you’re sure that encryption is for you, here are the steps:
From the Apps Screen, tap the Settings icon.
Scroll down and tap the Security link.
Doing so brings up the Security settings options.
Tap the Encrypt Device option.
As the screen says, have your password ready, the battery at 80 percent or higher, and an hour set aside when you don’t need to use your phone. This time, the password must include at least six characters with at least one number. In this case, the password “password1” is also off the table. This is the second-most-common lousy password that thieves routinely try.
