 Question 
Phone restarted automatically and Auto restart 
option is turned on. 
  
Answer 
    - From One UI 5.0 (T OS), 'Automation' with 
    sub menus are disappeared in device care and it has been changed to Auto 
    optimization and added with sub menus. Each function in 'Automation' menu 
    is re-arranged and integrated for optimization of features.
 
    - If the options are turned on, the phone 
    automatically performs optimizations by restarting the device.
 
    - That feature keeps the device running 
    smoothly all the time by automatically performing optimizations in the background.
 
 
  
    - You can use 'Auto optimization' feature 
    newly added in upper depth before. This includes closing background apps 
    and cleaning memory.  Automatic restarts will only happen when you're 
    not using your phone.
 
    - If you do not want the auto restart option, 
    you can turn it off in the settings.
 
    - To keep the device in the best condition, 
    you can set the option by turning on 'Restart when needed' or 'Restart on 
    schedule'.
 
 
  
[How to operate the 'Auto restart' feature] 
    - Auto restart option (default : Off): 'Restart 
    when needed', 'Restart on schedule'
 
 
    - Restart when needed on: The phone restarts 
    when the system gives notification that the native memory occupied over 
    30% at dawn (Users cannot check the condition, and the device restarts randomly 
    between 3 AM & 5 AM).
 
    - Restart on schedule on: The phone restarts 
    around at the day and time set by the user (The device restarts within +/- 
    an hour of the user's set time, not exactly at the set time. For example, 
    if the user sets the time to 3 AM, the device restarts randomly between 
    3 AM & 4 AM).
