I just recently setup our tablet device from scratch.
One thing that repeatedly came to the surface: software bloat.
After a factory reset, I deleted dozens of useless Android packages via Universal Android Debloater.
Even the default applications are bloat, e.g. the Huawei file manager requires 137 megabytes of storage, but Little File Explorer just requires 137 KILObytes.
This is 1000 times more storage space...
