On devices with encryption enabled that require you to enter a PIN before the device finishes booting, can any apps (including built-in ones like chrome or gmail) start before the PIN is entered?


If you are talking of Android N, then the answer is no, which uses File-based encryption and the following are enabled

AOSP Dialer (packages/apps/Dialer)

Desk Clock (packages/apps/DeskClock)

LatinIME (packages/inputmethods/LatinIME)*

Settings App (packages/apps/Settings)*

SystemUI (frameworks/base/packages/SystemUI)*

  • *System applications that use the defaultToDeviceProtectedStorage manifest attribute
  • 1
    Could Chrome start? And would I be correct in assuming, if it shows a PIN request before the lock-screen it's most likely using FDE, not FBE? – Nate D Dec 16 '17 at 2:51
  • I wouldn't know about Chrome (haven't checked it's permissions) but it's unlikely. Second part - Android N is mandated to use FBE not FDE – beeshyams Dec 16 '17 at 2:55
  • I just checked -Chrome doesn't declare that permission , so it won't start – beeshyams Dec 16 '17 at 2:59
