You need to understand that this tablet is budget, even for Samsung standards and therefore is quite limited in it's capabilities. Most of all the GSIs with countless customization options that I’ve downloaded from SourceForge work fine on my phone, but do not install on this tablet because of it’s limited system partition.
I’ve posted about this in a different thread, but if you are looking for the latest Lineage OS to run on this particular tablet flash this one:
I’ve been running it for the last month and besides no compatibility issues it’s much faster than the stock OS. No hate against OneUI 5, but this tablet’s specs handle Samsung’s latest OS poorly.
