I use s10+ for mostly basic tasks so don't have large number of apps yet perpetually I'm at 99% of internal storage prompting notification and apps that won't open because no storage. Every app that allows it is installed on sd, photos, music, etc all on sd. I done every trick such as clearing app data, empty trash. 19g is system, 108g 'other' and the rest stock apps that can't be moved to sd. Factory resets in past Galaxy phones after all Samsung and Google backups were completed always errored is some way, some settings, data or functionality was corrupted so I'm not doing that unless someone at Samsung wants to laboriously restore my phone afterwards. I like the galaxy gui and use Dex but, if a new phone is the only solution to this galaxy soecific problem, it won't be a galaxy.
- internal storage
I launched the (i) and turned off data use of native Samsung and android/Google apps I do use, no difference. I'd guess half my apps are now on SD and no help. Example: Gopro Quik allows wifi transfer of videos to phone for editing, upload to YouTube, etc. It only allows those files to go to internal storage where they can then be moved. I can't even load a 2gig vid from gopro temporarily to then move it.
Thanks much for suggestion, no change, 19g in system, 108g in other. I've previously cleared data in all apps possible but those mb recovered are insignificant. It seems like that 127g in system and other which is 99% of my 128g internal storage cannot be reduced.
