I am unble to delete all call log of particular contact in single click why in ios its not possible even a simple android phone this option is available.Apple should work on it

If an android phone better meets your needs then that is what you should get. Android and iOS are totally different platforms, and there are thousands of ways they differ from each other. While some features are the same or similar between the platforms, each has features the other doesn’t. So choose a phone based on the features that are most important to you.

Regarding this particular feature, iPhones don’t have a “call log” at all. They have a Recent Calls list, which is there to make it easy to return calls. For a call log go to your carrier’s user portal, which has a complete call log, usually going back 18 months. And calls cannot be deleted from it.

Apple doesn't read here in this user-to-user forum for feedback or suggestion. You can, however, let them know your thoughts here:
