Tips: ① Because this function is related to mobile phone hardware and system software, some models (such as A52) do not support recording system sound (or microphone sound). Please refer to the actual page display for specific support types.

② Privacy-related contents such as talking and chatting voice (WeChat voice, QQ voice) during screen recording are not allowed to be input by default.

(3) The sound button of the recording system needs to be turned on to record the system prompt sound (the incoming bell does not support input).

(4) If a software background occupies the recording channel, the recording screen can't input sound, just clear the background cache.

If the above methods still can't solve the problem, I suggest you take your mobile phone, purchase invoice and warranty card to the nearest OPPO customer service center for testing and processing.

This answer applies to all OPPO models.
