If you’re using multiple Google usernames on your device, or you changed the password(s) for a few, this may prevent a few apps from downloading through your Google Play application. As a user, it’s hard to tell what went wrong unless you go through all possible error causes. In this case, Google Play servers are unable to pinpoint the exact error code for these apps failing to download, so the app just tells you to keep “trying again” until the exact problem has been mitigated. In this example there are no error codes. A majority of failed download app issues on Google Play arise as a result of error codes such as “103,” “403,” “506,” and so forth.
As name suggests, the error is down to “something” malfunctioning on your phone which is the vaguest possible Android error definition.
