What is the automatic deletion of oppo mobile phone short messages?

Explanation on the limitation of the number of call records and short messages:

1, ColorOS 3.0 and above: the maximum number of call records is 3000.

2. For models with system version lower than ColorOS 3.0, the maximum number of call records is 500. After more than 500 articles, the earliest article will be deleted for each additional article.

3. For a single contact, only one call record is displayed in the dialing interface. After entering the call details interface of a single contact, the maximum number of call records is still 500.

4. When the storage space of the mobile phone is left, the number of short messages is not limited.

Tips:

Call records will be automatically saved in the phone and can be viewed on the dial. When the quantity is limited, the system will automatically delete the old records.

This answer applies to all OPPO models.
