Why is Samsung w2 1 slow to receive messages?

The reason why Samsung w2 1 receives messages slowly may be the connection problem between its own server and the network.

The process of pushing notification is that one party sends a message, then passes through the server and finally transmits it to the receiver. This will cause the push to be delayed as long as there is a problem at a certain stage, so users will only receive the message if they refresh manually.

Solution:

If the mobile phone receives the information delayed, it needs to start the background activity. If it is not turned on, it will not run in the background. If you receive the message, it will delay the time. Of course, the version of the APP needs to be updated.
