6. Application not workable
Possible reasons may be that this app is not compatible with your OS or the
downloaded .apk file is broken so you may need to download a full version.
8. How delete a Google account?
If an account is added, the account is shown in “Accounts & snc” of “Settings”,
where you may also add another account. To delete an undesired account, go
to “Settings” → “Privacy settings” → “Factory data reset”. Your tablet’s internal
storage, downloaded apps, etc. will also be deleted, except the info in your
flash memory. Be careful before you carry out this operation.
