 # Dump MB Logs 
+Author : Cuynu
 
 - Since v6.4.60+, MB hidden the `client.log` under `/data/data/com.mbmobile/cache` or `/data/data/com.mbmobile/app_flutter` even without internet connection. This make debugging even more harder for us. 
 - The only place where logs exists since v6.4.60+ is `/data/data/com.mbmobile/app_flutter/hive_databases` but it's encrypted and cannot be read.
