The newer Android devices that have Qualcomm chipsets have a choice when it comes to encrypting the data on their device. The first and most obvious is Android stock encryption that has been made available for devices that run Android 5.0 Lollipop or better. The other choice is to use the encryption process and algorithms provided by the Qualcomm chipset, as users of the OnePlus One smartphone have generally done. The good news? TWRP now supports the Qualcomm encryption process on the OnePlus One.
