My apps are not synchronized
Android has a feature called synchronization. Applications are synced to connect to the Internet for information. As a result the Twitter app notifies us that have retweeted one of our tweets. Sometimes, it may be that the applications are not synchronized. To solve these problems, we must go to Settings, and section of Auditors, find one that does not sync. We may disable syncing this account, and then turning it back on. If this does not fix the problem, we can check if the password with which we have signed is correct. Finally, we can delete the account and log back or delete the application and reinstall.
