Encryption is key to keeping your personal data as safe and protected as possible and here are the steps for how to enable it on the LG G4.
With all the talk about spying and the warrantless searches going on, it’s no doubt that more and more people are wanting to find out how to encrypt the data on their smartphone and tablet. Encrypting your LG G4 will use a secret key and scramble all of the data that is stored in the phone.
Unless someone has the key then the data is unreadable so if you decide to encrypt your device then be sure to not tell anyone what the password or PIN is.
Speaking of a password or a PIN, Android requires that you have a password or a PIN number security layer chosen before it will encrypt your device. That is because your PIN or password is the key to unscrambling all of the data you have on your phone. I assume this isn’t allowed with the pattern security method because it would be too easy to get around. If you try to encrypt your LG G4 without changing to a PIN or password unlock method first, Android will tell you to change this before you can proceed.
Warning – The only way to decrypt your device after it has been decrypted is by performing a factory reset on the LG G4. Keep this in mind before deciding to encrypt your device.
LG G4 Enable Encryption
- Plug In the LG G4 and Charge it to 100%
- Leave the Device Plugged In
- Launch the Settings Application
- Tap on the ‘Security’ Option
- Tap on the ‘Encrypt Phone’ Option
- Read the Warning
- Then Tap on the Encrypt Phone Button at the Bottom
Encrypting your phone won’t technically stop the NSA or some other agency from spying on the data that you have going back and forth from your LG G4. Instead, it will stop them from accessing the data if they are in possession of it. Say for example, you get arrested for something and the police confiscate your phone. There have been some court rulings that have allowed the police to search through your phone, without a warrant, if it is not encrypted. This doesn’t mean that they won’t be allowed to do so if it is encrypted. I’m just mentioning this because there is a precedent in both California and Canada.
Some might think this is being paranoid but I would personally rather be safe than sorry. The encrypt option for the LG G4 is inside the security section and be sure to read all the warnings for encrypting your device.
If you want to remove this encryption then you’ll have to perform a factory reset. It seems LG has added a way for users to decrypt the data. Thank you Daniel for looking into this. If something happens that interrupts the encryption process then you could lose some or all of your data. For this reason I recommend downloading and installing the LG PC Suite application and backing up as much of your data as possible before proceeding. Nothing bad should happen but again, I would rather be safe than sorry.
The encryption process can take up to an hour depending on how much data you have on your phone already. Please be patient and wait for the process to complete before you try turning it off or unplugging the LG G4 from the charger. Each time you reboot your LG G4, you will be asked to input your encryption PIN/password. This is the same PIN or password that you have set to unlock your LG G4. Android will use that PIN or password as the key to encrypting your device to be sure that you remember it. If you ever forget this PIN or password when you will have to factory reset your phone before you can use it again.
