SimpleMobileTools/Simple-Dialer — reverse-engineered prompt

Build me a simple Android phone dialer app like this project. I want it to feel lightweight, private, and easy to use, with no ads and no internet requirement.

The app should let people dial numbers with a big clear keypad, see smart contact suggestions while typing, search contacts and recent calls, and quickly call someone from the call log. It should support favorites, speed dial, and letting users create shortcuts for contacts on the home screen if Android allows it.

Please include basic call log management, like deleting one entry or clearing the whole history. Add number blocking so users can block specific numbers and optionally block callers that are not saved in contacts. It should also handle multi SIM phones where possible.

Make the UI clean and modern with a dark theme by default and customizable colors. Keep permissions minimal and only ask for what is needed for calls, contacts, and call history. Look up current Android docs if you need to.
