This might sound stupid but developers are often doing it: I would suggest to start comment from upper case. I would also suggest to finish with dot if comment contains more then single sentence.

this is one of the coding style rules that I hated the most while I was at Google. the value of the time lost when one senior engineer writes “please make this a sentence” and another senior engineer has to go into the code and fix it greatly exceeds any readability difficulties which may be caused by the lowercase letter and the missing dot

and not even the Android Kotlin style guide makes any requirements here
