I have now found some information on the net. It's actually 8 GB, of which 4 GB is already in use. But I think this is already lousy data. No wonder Samsung doesn't disclose this information anywhere. For me, this is a killer criterion. For comparison, the Sony XR-65X95L has 32 GB of storage space. Sure, you can swap apps to a USB memory, but that shouldn't be the solution. I can't understand why Samsung, as the industry leader, doesn't finally follow suit here. These few GB cost nothing these days.

4 GB (3.8 GB to be exact) 3 GB is already used by the preinstalled apps..🙄
