How do I set my phone to require the storage decrypt password after restarting? When an encrypted Android phone is started, this is what happens (to my best knowledge):


Boot phone
Decrypt storage, which requires PIN or password
Start up Android
Homescreen appears
(You may have to enter SIM card PIN code, but let's ignore this here)
Phone works, which requires PIN or password to unlock home screen


So password or PIN are required twice. Let's call these PIN1 and PIN2. On phone1, I have to enter PIN1 and PIN2. On phone2 I only have to enter PIN2. 

How can I configure phone2 to have to enter PIN1 as well?
After encrypting phone from Settings, Security
Head to Lockscreen, Screen lock, set the password afresh and check Require password or pattern on start up. 

And then you're automatically asked for it on power on. Take note that accessibility turning on disables this setting
