if you use droidfish, and use this Engine Stockfish 12, in the set option engine there is debug log file ... please someone explain what the function is
Its just a log file when engine is loaded in main memory its generates some info it can be save in log.txt file and later can be viewed. You can also try just type this in Debug log file /storage/emulated/0/Droidfish/log.txt It will generate a log.txt file according to your system and settings.
