Thanks for the feedback, @Rilot !
Unfortunately my old device already has 8GB of RAM, and there won’t be any improvement if I switch to a S23 (unless I by a S23 Ultra, which would also provide a bigger screen, but it is much more exensive).
Indeed, the quality is much lower when post-processing using a mobile device. I really only want to use it to check if everything seems to be ok when scanning on location, so that I can make sure I won’t have to come back. 
I actually included a mobile/PC postprocessing comparison in my INSPIRE showcase video, at 3’57’': the difference is jaw-dropping.
