We recommend you to clean the cache regularly or download some cleaning software.
Please check if the system gets slow after installing certain software, please have a try again after deleting it.
For this issue, we suggest you to restore factory settings.
Why the app would exit automatically and respond slowly?
Make sure you don't run many or large-sized apps at one time.
You could clean the caches in your tablet regularly in case the RAM gets overburdened. Go to Setting-Apps, and click the app to clear cache or data.
You could also do a reset: please go to "settings"--scroll down the menu--press "Backup & reset"--"Factory data reset"--"reset tablet"--"erase everything". The reset process will take a couple of minutes, then the tablet will turn on by itself.
Also, you could install the app "Ccleaner" which can help your tablet stay clean to run smoothly.
Why the app from Google Play is not working/apps cannot be downloaded or opened?
Account information is not recognized: Please re-login your account and try again.
Caused by download manager: clear the application data of the download manager and Google play, then reboot the tablet.
Caused by downloaded apps: Please check the menu and see if there is only one app downloading, the tablet only supports to download apps one by one.
Restore factory settings: if it is still not working at all, please restore the tablet.
