Filter the Call History List auf Oppo
On Oppo phones running ColorOS, the stock Phone app pulls its call log design from Google, which keeps the filter options intentionally minimal. Every incoming, outgoing and missed call lands in one continuous list by default, making it hard to track calls you never returned once the log grows past a few dozen entries.
The app does include a basic filter, but it sits inside the overflow menu instead of a visible toggle. To reach it, tap Phone, open Menu, tap Call history, then choose either All or Missed. Selecting Missed hides every answered and outgoing call, leaving only the numbers you did not pick up.
This filter usually resets back to All the next time you reopen the call log, so you need to reapply it whenever you want the missed-only view again. If you are hoping to separate outgoing calls from incoming ones, this menu will not help, since ColorOS only distinguishes between the full list and missed calls.
Clearing the entire call history is a separate action and has no effect on this filter setting.
