Why isn't the file being validated in Laravel on Android?

Laravel 5.1, Android any

There is a Controller with Request'om in which it is checked that the field is a file. On PC, ios everything works fine. But when you send a request from any Android device, the validation on the file does not pass. What could be the problem?
