You must have taken some pictures, making online transactions, have important people contact details, and many other such things on your Android device. These all data are important and personal, which should stay intact and should not fall into the wrong hands. For this, you should consider encrypting your device.
What is Device Encryption and what does it do:
Before we go in details on how to enable it, it is probably best to understand what exactly encryption is and what to bear in mind about it.
Device encryption is not a one-stop solution for protecting all of your data and information from prying eyes, especially when you are sending data over the internet. Instead, device encryption converts all of the data stored on your phone into a form that can only be read with the correct credentials. This goes above and beyond a regular lock screen password, as data can still be accessed from behind this screen with some specialized knowledge and use of recoveries, bootloaders, or the Android Debug Bridge.
Once encrypted, your music, photos, apps and account data can’t be read without first unjumbling the information using a unique key. There’s a fair bit of stuff going on behind the scenes, where a user password is converted into a key that is stored in a “Trusted Execution Environment” to keep it secure from software attacks. This key is then required to encrypt and decrypt files, sort of like those alphabet cypher puzzles that scramble up letters.
How to Encrypt Android Phone:
Before you start the encryption process, make sure that your device battery is fully charged and also it is plugged in charging. The process can take an hour or more depending on the size of your data. Another important thing to take care of is that you should not interfere the process in any manner, in case if you do, you are likely to lose some or all the data on your device.
1. Launch Settings app on your Android device and then tap on security.
2. Under Encryption head, tap on “Encrypt phone
3. You’ll see a long warning message and at the bottom a button saying “ENCRYPT PHONE”, tap on it.
4. At the next screen, you’ll again see a warning message which we already gave you above. Here again, you’ll have the same button saying “ENCRYPT PHONE”, tap on it.
Your device will now reboot and start the encryption process along with estimated time and progress bar. Just wait for it to complete and relax for a while. Once the process is finished, the device will boot again as normal and you’ll be asked to enter the pattern or pin code if you have set any.
That’s it; your device is now encrypted and now you’ll not have to worry about the data even if you lose your device.
