Respostas para as perguntas mais comuns sobre nossos testes de dispositivo no navegador.
Não. Cada teste nesta página é executado dentro do seu navegador usando APIs web padrão. Não há nada para baixar, nenhuma extensão para adicionar e nenhuma conta para criar.
Não. Os fluxos da câmera e do microfone são processados localmente no seu navegador e nunca saem do seu dispositivo. Não gravamos, armazenamos ou transmitimos nenhum áudio ou vídeo.
Se você está se preparando para uma chamada de vídeo, comece com a Verificação de Prontidão para Reunião — ela testa câmera, microfone, alto-falantes e rede em uma única passada. Para um único dispositivo com problema, vá direto para o teste desse dispositivo.
Sim. Os testes de câmera, microfone, alto-falante, tela, toque, sensor e rede funcionam em navegadores móveis modernos. Alguns testes, como MIDI e suporte a controladores, dependem do navegador e do hardware.
Alguns navegadores restringem certas APIs. O Safari, por exemplo, não implementa Web MIDI. Tente o mesmo teste no Chrome ou Edge e verifique o Teste de Permissões para garantir que nada esteja bloqueado.
Our guias de solução de problemas walk through the exact fixes for a camera that won’t start, a mic nobody can hear, missing sound, Wi-Fi dropouts and overheating laptops on Windows, macOS, Android and iOS.
