Risposte alle domande più comuni sui nostri test del dispositivo tramite browser.
No. Ogni test su questa pagina viene eseguito all'interno del tuo browser utilizzando le API web standard. Non c'è nulla da scaricare, nessuna estensione da aggiungere e nessun account da creare.
No. I flussi della fotocamera e del microfono vengono elaborati localmente nel tuo browser e non lasciano mai il tuo dispositivo. Non registriamo, memorizziamo o trasmettiamo alcun audio o video.
Se ti stai preparando per una videochiamata, inizia con il Controllo Prontezza Riunione — testa fotocamera, microfono, altoparlanti e rete in un unico passaggio. Per un singolo dispositivo guasto, vai direttamente al test di quel dispositivo.
Sì. I test della fotocamera, del microfono, dell'altoparlante, del display, del touch, del sensore e della rete funzionano tutti sui browser mobili moderni. Alcuni test, come MIDI e il supporto del controller, dipendono dal browser e dall'hardware.
Alcuni browser limitano determinate API. Safari, per esempio, non implementa Web MIDI. Prova lo stesso test in Chrome o Edge e controlla il Test dei Permessi per assicurarti che nulla sia bloccato.
Our guide alla risoluzione dei problemi 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.
