We have released a free Unity Asset. It is called Remote Logger via Google Sheets and you can download it directly from Unity Asset Store.
When a tester or a real player have found a bug logging is usually the key tool to investigate the issue. Saving and sending the logs to you is usually a time consuming task for the tester. Quite often a real player can’t do it at all. Remote Logger allows watching and saving the logs remotely.
The used approach is quite simple. You create Google Spreadsheet, this table will display and keep logs sent from client. The client sends logs when Remote Logger is switched on. Activate it by default in your test build. In case of production build you can send activation instruction to the player. For example, the player can do it pressing special button in game’s settings or changing device date to specific value (this approach is useful when the application doesn’t run).
