## Review summary

OTG Guru app is appreciated for effectively showing detailed USB device information, especially by tech-savvy users needing raw data about devices connected via OTG cables. It is praised for simplicity and reliability in many cases. However, multiple users report issues like the app failing to detect connected devices and showing zero devices without error messages. The lack of user guidance and additional features, like USB generation display, is noted as a downside. Overall, it serves its purpose well for technical users but might frustrate others due to occasional functionality problems and minimal interface support.
