How to Encrypt an Android Phone to Keep Information Safe and Secure
A good foremost step security meter to protect against data personnel casualty is setting up a lock screen with a PIN, password, fingermark, or pilfer keystone. It ’ s an excellent deterrent for casual thieves, but the data itself is still fairly easy to retrieve, despite the filmdom lock. fortunately the Android operate organization comes with a handy security feature that can encrypt your device from head to toe, locking down private information so it ’ randomness about impossible to retrieve. It’s also a good idea to add an app to remotely wipe your phone in the event that it is stolen .
Encrypting an Android call is a amazingly simple tax and only requires a few minutes to start. With a little preparation and the veracious tools, you can lock down your device and keep your data condom and guarantee.
What Does Encryption Do for Android Phones?
The encoding process works like an fabulously complex interlock and key. Files on your earphone are normally stored in a raw format, something akin to an unfasten padlock. Anyone can stroll by and take a expression at those files or, with the right equipment, make copies for themselves. This can even happen behind your purportedly secure screen lock !
When you encrypt your earphone, all of the data stored on the device gets converted into randomized numbers and letters. Like fastening the padlocks, the information is stored in an indecipherable state, basically good a down of meaningless code. With the right key, however, those padlocks can be unbarred and converted back into their original format. The only keystone that works with the locks is the one created by your device when you enter a password or PIN during the encoding process .
An code phone stores all of its idle data in a safe format. nothing is decrypted until you enter your key, and nothing can decrypt those files aside from that specific key. This makes encoding an incredibly effective privacy joyride that renders stolen data closely useless. It ’ s not perfect, but it serves its aim for the huge majority of users .
Benefits of Android Phone Encryption
privacy is the phone number one benefit of encrypting your Android device. Whether you ’ re concerned about hackers stealing information or nosy strangers unlocking your call, encoding is the answer .
1. Protect sensitive personal information
Cell phones contain a treasure trove of private information. e-mail accounts, passwords, trust logins, touch numbers, browsing history, your dwelling address, and so much more, all neatly filed in a unmarried device.

1. Longer boot times
Rebooting an code phone takes approximately twice a long as unencrypted devices, all due to the security command processing overhead time. You besides have to enter your PIN or lock screen password every prison term you reboot, which can be annoying for some users .
2. Sluggish operating speed
Have you ever noticed your call slows down when playing certain games or running a lot of apps ? This can happen when the device ’ s processor gets overloaded trying to handle excessively many tasks at once. encoding increases the load on your device ’ s CPU, which can make slowdown worse and occur more frequently. The trouble is scantily obtrusive on newer, more herculean devices, but the buttocks line is if your earphone is encrypted, you should expect some slowdown .
3. Encryption isn’t bulletproof
even with a building complex interlock screen blueprint and fully disk encoding enabled, it ’ randomness even technically possible to obtain data from your device. These methods are normally reserved for skilled hackers, however .
4. Full decryption isn’t really possible
once you encrypt your device, the only manner to decrypt the integral phonograph record is to do a factory reset. Make sure your data is backed up externally before encrypting, as there ’ s no undo button for this process .

Important: Android Encryption Doesn’t Encrypt Internet Traffic
The independent function of encrypting your Android earphone is to prevent localized data larceny. Files on your device are stored in a code format, making it about impossible for person to pick up your telephone and steal your data. adenine soon as you provide the keystone and start using a file, however, that encoding is temporarily unwrap. This means active data you send through the internet is nobelium long encrypted, which can put you at risk.

With both local encoding and an active VPN, your data will be safe on your phone vitamin a well as across the internet .
Will Encryption Slow My Phone Down?
regardless of the technology or devices involved, encoding about always slows things down. The process of scrambling data and unlocking it with complex keys takes an enormous come of time and processing power. The more data involved and the more building complex ( and guarantee ) the encoding, the longer it takes. This holds true for CPU intensifier tasks equally well as dim-witted things like opening a world wide web browser or using an master of science broadcast .
Most modern Android phones and tablets deal with the encoding overhead without excessively much trouble, making slowdown minimal and scantily noticeable. If you have a slenderly older device or frequently use CPU heavy apps, however, you ’ re likely to encounter some imprison. The only authentic solution to this is to upgrade to a more herculean device .
Encrypting the microSD Card

The process of encrypting the microSD card is the same as encrypting the phone. Tap the option under Settings > Security, insert your pin or password, plug your device into a power reference, then wait for the encoding to finish. Depending on the speed of your earphone and the come of data on the poster, this could take a few minutes to an hour .
Encrypting the microSD wag carries a few drawbacks. For starters, you won ’ thyroxine be able to use the menu in another device unless you decrypt and format it first. This besides means that resetting your phone to factory nonpayment destroys the encoding keys to decrypt the card, making the datum irretrievable .

That leaves a distribute of unprotected phones out in the wild .
If your telephone or tablet is newly and already has Android 6.0 or better, chances are the entire phonograph record was encrypted before you even turned it on. To verify, just go to Settings > Security and scroll polish to the section that says “ Encrypt earphone ” or “ Encrypt pad “. If encoding was already active, the text should say “ Encrypted “ .
Difference Between Encrypting and Setting a PIN or Password Lock
encoding and screen locks are two separate activities that aren ’ t necessarily linked together. Just because your phone asks for a PIN, password, swipe model, or fingerprint to pass the lock blind doesn ’ t mean your data is encrypted. In fact, data can still be accessed with a screen lock in place, all the intruder needs is a USB cable and a little time .
encoding ensures that even if person gains access to the data on your device they won ’ thymine be able to take anything useful. Without the key provided by your password and the Android device that encrypted the information, all anyone can take is a confused batch of numbers and letters .
Can All Android Devices Do Encryption?
not every telephone, tablet, or device powered by Android will have full disk encoding as an choice. Most e-readers, gaming consoles, and Android TVs skip the have for a numeral of reasons, the independent ones being a miss of processing power. These devices are reasonably low hazard vitamin a far as data larceny is concerned, so the lack of an encoding option international relations and security network ’ t a boastful deal .
If your earphone or Android device doesn ’ thymine put up wide encoding, you can always download an app that encrypts individual files or folders. See below for a choice of recommend programs .
