Which tablet app/browser is suitable for a store to allow customers to leave reviews?

Question

Android

Hello!
There is a small web application that runs in a browser with a customer survey.
There is the simplest tablet on Android 7.0.
Task: place the tablet in the client area so that clients can complete the questionnaire themselves by clicking on the tablet.
The main problem is that people can easily start clicking in unnecessary places. How can this be prevented? An application, perhaps, or a full-fledged new firmware?

Answer 1

The device can be configured to run only one application.
