Hi,

please attempt to use another internet source before attempt to access the app store on your tablet. This can be either ethernet or tablet. If this fails, please restart your tablet once or twice. Otherwise, you might need to transfer antivirus apps via usb into your tablet, install/run those and then attempt to access your app store again.

Thank you.

Google Play Services, the preinstalled app on your phone plays an extremely crucial role in the regular running of your lenvono. If anything is wrong with it, then your lenovo will start throwing fits in the form of errors and crashes including 'Google Play Services keeps stopping' error.
To remove the error, you need to fix Play Services. Here you will find numerous ways to fix any issue related to Play Services. Let's get to know them.
1 Starting with, will actually with restarting you Lenovo.
2 Another that does wonders for any issue is to "clear the cache" and date of the particular app. In this case, we need to clear cache and data for "Google Play Services" and "Google Play Store".
Doing any of that will not delete any data from your phone. However, clearing data will log you out from Play Store and reset its settings. In settings
3 "Google Play Services" is a system app, you cannot remove it from your lenovo completely. However, you can uninstall the updates, which will revert it to the factory version forcing your phone to update it automatically, thus fixing any issue.
On the Google Play Services screen, tap on the "three-dot" icon at the top-right corner. Select Uninstall updates from the menu.
4 Unlike other installed apps, you don't have to update Google Play Services manually. It's done automatically in the background by your lenovo.
However, sometimes, the issue is with the update itself. So you need to update it to the newer or older version manually. We have covered ots of ways to update google play service in detail. Do check that. And if you face any issue while updating it, check fixes.
6 Similar to restart, sometimes booting in the safe mode fixes various issues on an Android phone. Again, doing that will not delete you data and you can access it in safe mode as well. Running the lenovo in safe mode also helps in identifying the issues caused by the third-party apps.
I hope these will get you over your issue with ease.
