My tablet keeps optimizing apps. Sometime 10 out of 100. How can I correct this?

You may have to reset it to factory settings. Never break optimization process. It may take a while if there is many apps installed

On slower device and many apps it can take long time to optimize all apps. Leave it for longer time and let the process to complete.

Try these listed suggesttions:
- Make sure your iPad is running a version of iOS that the app is optimized for, it cannot be lower than what the app is optimized for, it can either be the optimized version or higher.
- Try going to the chpp Switcher by pressing the Home button twice quickly, and close the game, then reopen it.
- Reboot your device by holding down the Home and Lock button for 10 seconds.
- Contact the developers that made the game, cuz who knows, it might not be your device, it might be the game as well.
Hope this helps! :)

are you waiting for tablet to finish upgrading and optimising be patient

wait for operation to stop

Go into you applications and decide upon which apps you do not need our use. Select the app, and then uninstall. Run a cleaner app afterwards to ensure tablet is optimized.

Try cleanmaster app, it seems to work well on my phone and my android tablet.

I had the same problem. I finally realized that it wants you to select the country, however the drop down list is blank. No resolution! I finally ended up using the amazon app installer. Pain in the butt, but it works. You just need to set up an account with amazon and download the android app installer. Hope this helps.
