Please log in for more thread options How does one access data on a computer? Two ways: locally and remotely.
Remotely accessing data in main memory on a smartphone would always result
in the clear-text data leaving the device, even if the data is encrypted in
main memory.
Locally accessing data in main memory requires physical access to the
device. If the device is protected by a PIN, I don't know of any way to get
to the data without first supplying the PIN.
Just because someone wants to sell you something, doesn't mean that you need
it. Additionally, just because a security feature exists, doesn't mean that
it should be enabled.
