I was hoping someone might have some suggestions on fixing a -999 error I'm receiving when I try and download a theme on my s9. This has been going on for about 10 months. I can see all the themes in the store and it appears that the themes are being downloaded when selected but the -999 error appears after the "completing download" message appears. On a related note, Dynamic Lock screen images also will not download. Installation hangs after it appears the download is complete.
Fixes I've tried include:
I'd like to avoid doing a factory reset on the phone because the last time I was forced to do that, this problem started. It also took me weeks to get everything back up and running.
Does the Theme app rely on another app for managing downloads and maybe that one is corrupt?
