If you have a flip phone, there are a few ways to delete missed calls. You can use the call history to find the call that you want to delete, or you can use the call blocker. The first way is easier, but it doesn’t work if the phone is locked. To delete a missed call, open the phone’s settings and select “Call history.” Scroll down and select “Delete.” If you’re using a lock screen or password protection, make sure those are enabled as well. The second way is more difficult but it works if the phone is unlocked. To delete a missed call, open the phone’s settings and select “Call blocker.” Scroll down and select “Delete.” If you’re using a lock screen or password protection, make sure those are enabled as well.
