Thank you for your help but the screens that you told me to go were all different from what you said:
1. Home Screen
2. Telephone Icon
3. Last Caller's number only, not the whole list
4. Clock icon- bottom right
5. Call log appears, I select the caller I want to delete
6. Only 2 choices: Call this number or text this number. Nothing else. The 3 horizontal stripes(hamburger) puts me back to the previous screen. The Clock icon bottom left puts me back to the previous screen.
You know, this evening I had to search for 4 other How-to-do for different procedures, each took me 1 hour to try, but only one was successful. 4 hours - in one day. And it happens everyday. I need 200 years to live to accommodate. Only if people gave PRECISE instructions and removed all the outdated instructions on the web. I'm really tired. Thanks.
