How to trace running instructions/taken branches on physical Android smartphone?

Question

This is the situation: I have my own smartphone and I want to trace every time I make a service call with

adb shell service call ...

which instructions are covered or which branches are taken in the service code (both java and c).

I tried to give a look to hardware solutions, but it read that vendors usually disable this debugging option.

Any ideas or useful tool for me?
