Untitled messages are MMS or spam messages. The reason may be that the sender forgot to write the theme, or it may be because the 4g network is not enabled and cannot be displayed, or the network is unstable when the mobile phone receives the short message, the data packet is lost, and there are software-level things in the background of the system that block the short message, resulting in incomplete reception.
