Trying to perform a system update crashes the Settings app
There a couple of things you can try out, in any order you like!


New Tablet? Surprising, try a factory reset if you have nothing on it. This should fix it for most cases.
A single application crashing could be due to some stale values associated with the data it has cached, you could try force stopping the settings application and then clearing the storage.


If this doesn't work, check for the latest stable build of a rom for your device from the vendor itself, you might have to flash it.

Edit:

Just saw Jeff Chang's comment, and my answer is similar to the one on the link he provided. If it works, you can ask him to answer it for you and award him the bounty.
