Currently, removing the cache does the job much better. The only thing
clearing the cache doesn't do which "reset" did is removing the databases. But
we don't want to do that anyway.
If someone wants to do that, they can just deactivate or remove a repo, and it
will get wiped from the database.
A ridiclous number of apps claim to be incompatible with devices that
don't have a touchscreen. This even includes devices that have the 'fake
touchscreen' feature instead. Nearly all of those have no such
requirement, so this preference allows you to ignore it and treat those
apps as being compatible.
By default SQLite runs with synchronous=FULL, which is the safest mode
and uses fsync() a lot, but this interacts very badly with Samsung's
infamous RFS filesystem. With this preference the user can decide
whether to sacrifice some safety for reasonable performance.
