Ubuntu Touch OTA-5 Update will arrive on the Bq Aquaris E4.5 and Bq Aquaris E5 tomorrow, the update for the Meizu MX4 being not ready yet.
As a reminder, Ubuntu Touch is a stable operating system, but it is not mature enough, compared to Android and iOS. For now, there are three Ubuntu Phones: Bq Aquaris E5 HD, Bq Aquaris E4.5, Meizu MX4, but the system is also officially supported on the LG Nexus 4 device.
