@matteo I think not, because it's Exynos chipset, this I believe was done for Snapdragon devices. But I might be wrong?

@pglushkov As @Lakotaubp explained there

@thilov you can install Torch by:
open terminal
type: sudo -i
you'll be prompted to type in your password, do it
then type: sudo ubports-qa install PR-22
confirm by : y when/if asked
then type: sudo apt install indicator-power
reboot

after reboot, on dash under battery icon will appear a flashlight.

@Flohack Is calling via Bluetooth working as well or is it just sending a files/streaming music?

@pgp You would need to resize the .cache partition on your phone. It's too smalll to contain all the files needed to flash 16.04
Search Increase Cache Partition on this forum, you'll find the answers.

Official Ubports won't work, install it with ubuntu-device-flash from Terminal.

Edit: also need to remove all files from .cache/recovery as it is now full of files from unsuccessful instalation.

@AsgerBj Install TWRP, reboot to recovery, wipe the phone, format data ( it ask you if you sure, needs to type ''yes'')
Reboot to recovery again.
Change the file type to ext4 on Cache and Data, all of this with TWRP (no fastboot).

Try to install again with Ubports installer.

@mihael Sadly, not any improvement. Sound did not get through, it did connect to Volvo Truck Bluetooth though. But it never worked on Pro5...

@ziggutas that's a known bug, also sound doesn't work when calling on to OP3, (also it won't wake up the screen, sometimes when screen is on , the call UI crashes leaves active call inaccessible ) sound works when calling from OP3 .
This behaviour was observed on @vince1171 port, now have the same issues on Ubports arm64 version as well...go figure... hopefully this could be resolved, it's a main stopper.
I don't think anyone reported that yet to Ubports.

@Lakotaubp Mateo Salta posted on UBPORTS telegram group the click, last night at 8:46, I think you can install via Terminal.
