Lenovo s820 always displays "hidden sending address"

I'm sorry for the inconvenience.

Regarding your feedback, I suggest you drop down the notification bar on the screen to see if there are unread SMS reminders, or enter SMS to see if there are unread SMS reminders. According to my personal understanding, if you receive such a short message reminder, it is not excluded that the short message sending function may be hidden for the other party. For example, if you enter the short message function to check the content of the short message, but there is still this reminder, I suggest you set-backup and reset-restore the factory settings, and please back up some important files stored in the machine before resuming the operation.

If you still can't achieve the above functions, you can go to the Lenovo after-sales maintenance site nearby for testing. Lenovo authorized maintenance site inquiry:/Lenovo/WSI/station/servicestation/default.aspx? Intcmp=MIDH, the service hours of maintenance stations are generally 9:00- 18:00 from Monday to Sunday, except holidays, and local stations will adjust slightly according to their own operation conditions. I suggest you call for detailed consultation before you go. Please refer to.

You are welcome to contact us at any time or visit Lenovo Lewen Bar () for consultation and understanding.
