UBports is a fork developed by Canonical's Ubuntu Touch mobile operating system community. The latest version of the project is UBports 16.04 OTA-20.
The new version brings several changes to the notifications.
"We have implemented LED notification support for Halium 9 based devices. If your device is still not flashing, keep in mind that many recent devices no longer have an LED notification: the Vollaphone and Pixel 3a cannot flash naturally. Also, vibration now works for incoming alerts on these devices. We've added support for Khmer and Bengali fonts to better support users of these locales. It is now possible to set a custom alert tone. As with ringtones, you can now select any accessible audio file to play when a new alert arrives. Let us annoy our colleagues with style!
Some new devices have been added to the list of devices that can be installed: Xiaomi Redmi 9 and 9 Prime (lancelot), Xiaomi Redmi Note 9 (merlin), Note 9 Pro (joyuese), Note 9 Pro Max (excalibur), Note 9S (curtana) , Xiaomi Poco M2 Pro (gram) and Pixel 2 (walleye).
However, the Pixel 2 has some problems with battery life, so it may not be fully ready for everyday use.
Additional information is available at announcement of the new release. Supported devices and download options can be found at UBports download page.
