Dual-sim mode gap between introducing both PINs
(Issue title)
[dual-sim mode] between introducing both PINs there's a gap
Summary
First thing after booting an /e/-phone: the user need to type the PIN code to unlock his/her SIM card. In case, 2 SIM cards are used, both SIM cards need to be unlocked by PIN codes. There's a tiny issue when introducing the second SIM card
Steps to reproduce
Reboot phone Type PIN code 1 on the first input screen
- Now input screen 2 is appearing right after and the user may type PIN code 2,
- Only a second later the phone's home screen is shown briefly and
- then input screen 2 pops-up again.
If the second PIN code was typed-in in this second before the home screen appeared briefly, the typed-in PIN vanishes.
What is the expected correct behavior?
- Input screen 1
- Only when PIN 1 was entirely processed, input screen 2 should appear (in case it is necessary for technical reasons to show briefly the homescreen, input screen 2 should ONLY appear afterwards.
There should be no possibility where there user may type something that cannot be noted by the system at that very moment.
