1.Due to the increasing challenges for our engineering teams to maintain the product on old dated OS versions, we had to make the difficult decision to end releasing App updates for devices running on OS versions lower than Android 5, starting January 1, 2021. Please upgrade your device to Android 5.0 or higher to get the most out of your EZVIZ devices. We apologize for all the inconvenience.
