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".

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.
