Flash the Samsung firmware for your tablet via downloaded firmware from sammobile matching the model number and region of your tablet.

You need to do this with the tablet plugged in and booted to download mode. Instructions on how to do this are on every download page of every firmware on sammobile website.

This should fix your problem otherwise you need to do a factory reset probably.

But why did this happen after 18 mos of use? Mine is the same, 6 minutes of optimizing.


The only things I can think of are:

- Bad app installation

- Android System Software Update is not optimized apps properly.
