Video decoding is now fixed!!

Please download the latest CI from 17-01-2020.

Call echo has already been fixed on devel.

EDIT: as for the 48MP camera, the sensor is 48, but output is only 12 according to Samsung: https://www.samsung.com/semiconductor/minisite/isocell/mobile-image-sensors/isocell-bright-gm1/

Please download the latest version of UBports installer and install it. You'll need to check "Wipe userdata" in the installer if you're from Android OS.

@smoozz The unlocked splash screen is just what shows up if the phone bootloader is unlocked.

I've been trying to get in contact with the UBports admins to add a custom splash screen which shows "powered by ubports foundation" but to no avail.

@danct12 And now it's added, soon will be added to the installer. If anyone wants to try it out here it is: https://cdimage.ubports.com/devices/lavender/splash.img

@siucdude Hi, that seems to be a issue on some devices. I have made a bug report here: https://github.com/ubports/ubuntu-touch/issues/1695

@arnd Ubuntu Touch GSI on any device is NOT officially supported by UBports Foundation.

As this device is officially maintained by us, we suggest you use UBports Installer to install this port.

@mrn Thank you, I'll ask our developers to fix the issue soon.

@maldukhn Please post ~/.cache/ubports/ubports-installer.log on paste.ubuntu.com

@sativista I suggest trying another cable, that worked for me.

@joaofl Yep, there was some bug that only occurs on "stable" channel, devel and rc works fine.
