I have picked ap a Galaxy TabPro S a year or two ago, but didn’t end up using it much since it was running Windows. I had always planned to try out Linux on it, but never got around to it until now. I installed Xubuntu, just to have a light OS, & the only issue is related to getting wireless working. It is however a quick fix:
Just need to clear the contents of /lib/firmware/ath10k/QCA6174/hw3.0/*, & then place the two files from the GitHub repo. After a reboot, wireless was working with no additional changes needed.
