Jawaban atas pertanyaan paling umum tentang pengujian perangkat browser kami.
Tidak. Setiap pengujian di halaman ini berjalan di dalam browser Anda menggunakan API web standar. Tidak ada yang perlu diunduh, tidak ada ekstensi untuk ditambahkan, dan tidak ada akun untuk dibuat.
Tidak. Aliran kamera dan mikrofon diproses secara lokal di browser Anda dan tidak pernah meninggalkan perangkat Anda. Kami tidak merekam, menyimpan, atau mengirimkan audio atau video apa pun.
Jika Anda sedang mempersiapkan panggilan video, mulailah dengan Meeting Ready Check — ini menguji kamera, mikrofon, speaker, dan jaringan dalam satu kali jalan. Untuk satu perangkat yang rusak, langsung lompat ke pengujian perangkat tersebut.
Ya. Tes kamera, mikrofon, speaker, layar, sentuh, sensor, dan jaringan semuanya berfungsi pada peramban seluler modern. Beberapa tes seperti MIDI dan dukungan pengontrol bergantung pada peramban dan perangkat keras.
Beberapa peramban membatasi API tertentu. Safari, misalnya, tidak mengimplementasikan Web MIDI. Coba tes yang sama di Chrome atau Edge, dan periksa Tes Izin untuk memastikan tidak ada yang diblokir.
