According to media reports, vivo recently released a mobile phone using a Mediatek chip, but did not use Qualcomm chips. Therefore, it can be believed that vivo did not purchase Qualcomm chips. This may be because vivo wants to improve its own chip research and development capabilities, or it may be because the price of Qualcomm chips is too high and does not meet vivo's cost control requirements. Whatever the reason, vivo's approach is worthy of respect and may shed some light on the industry as a whole.
