If it is due to your own reasons, you have to adjust it manually

After recording the song, you can adjust the vocals forward and backward

If it is due to the equipment, you have to change the equipment

Equipment issues:

The mechanical signal from your voice to the microphone diaphragm and finally the digital signal in the mobile phone require a calculation process. This process is what the sound card does. But after all, mobile phones are still too highly integrated and do not have a separate chip or module to handle this, so their performance will be lower than that of computers.

Even a computer’s professional sound card will have sound delays. This is unavoidable due to principle issues, but the delay of professional sound cards is within the range that the human ear cannot detect.

Second, recording songs on mobile phones is a bit worse with Android. This is due to the poor performance of Android from the bottom to the upper layer. After all, Java is not an efficient programming language. In comparison, the execution efficiency of iOS is indeed higher.
