UBports Releases Ubuntu Touch OTA-4 for Ubuntu Phones, Based on Ubuntu 16.04 LTS

Ubuntu Touch OTA-4 is the first release to be based on the Ubuntu 16.04 LTS (Xenial Xerus) operating system series, which means that it includes more recent and up-to-date components than all previous releases, which were based on the older and deprecated Ubuntu 15.04 (Vivid Vervet) operating system series. Therefore, Ubuntu Phone users that have a supported device (see below for supported devices) will now run a much-improved Ubuntu Touch mobile OS that runs recent technologies, such as the long-term supported Qt 5.9 application framework, which brings performance improvements and new features.
