What does it mean that there is a circle on the mobile phone screen?

If you notice a circular icon on the screen of your mobile phone, it means that your mobile phone is using location service. This is a common sign that many applications need to use location to provide a better experience and service. However, this should not lead you to ignore your personal privacy. When using these applications, you should always ensure that your personal information is protected and do not share it with untrusted third parties.

Sometimes, the circular icon will remind you that there are unread notices. This may mean that you have received a notification from email, SMS or other applications. This is a good reminder to help you find important information in time. However, you should always check the notification center to ensure that you have not missed any important information or events.

Another possible reason is that when your mobile phone is charged, a circular icon will appear. This means that your mobile phone is charging, and clearly indicates the charging temperature and remaining time. This function is very useful, because it can help you know the charging situation in time, ensure that your mobile phone gets the best charging experience, and may extend its battery life.
