Hello @asifbadat, below will be some simple fixes to get your ***Google Play Store*** working.[br]
[br]
[br]

1) Restart your device which can often resolve temporary issues.
2) Clear the Play Store data by going to ''Settings > Apps > Google Play Store > Storage > Clear Data.''
3) Clear Google Play Services cache by going to ''Settings > Apps > Google Play Services > Storage > Clear Cache.''
If any of the ideas I had sent to you today don't work, I suggest giving Samsung a call.[br]
