+# Check "Obsidian vConsole" Output
+
+It's quite hard to debug on mobile. But fortunately you can use another plugin to rescue!
+
+This applies to both iOS (iPhone / iPad) and Android.
+
+## Disable Auto Sync Firstly
+
+You should disable auto sync to avoid any unexpected running.
+
+## Set The Output Level To Debug
+
+Go to the plugin settings, scroll down to the section "Debug" -> "alter console log level", and change it from "info" to "debug".
+
+## Use "Obsidian vConsole"
+
+1. Install the third-party plugin ["Obsidian vConsole"](https://github.com/zhouhua/obsidian-vconsole).
+2. Enable "Obsidian vConsole". You shall see a green button in the right buttom corner of the interface of your mobile Obsidian. You can drag this green button to where you like.
+3. Sync! And quickly click the vConsole green button, you will see the console logs in its panel! Moreover, you can check browser network and Storage (LocalStorage) in the panel! 
+4. You can copy (by clicking the small "disk" icon beside each line of the log) or take a screenshot of the logs, and report bugs in Remotely Save GitHub. You can click "Hide" in the panel to hide the panel.
+5. If you don't need to debug any more, you can disable Obsidian vConsole plugin, then the green button should disappear.
