It is often challenging to access the pre-launch test results of a well-known brand product, as this information is usually confidential business information and is strictly protected. However, there are a few points to consider: 1. **Internal leaks**: Sometimes internal employees may leak information, but this practice may involve legal issues. 2. **Hacking**: Illegal breaking into the company system to obtain information. This behavior is illegal and seriously violates ethical and legal norms. 3. **Industry insiders**: Obtain information through industry insiders, but this usually requires reliable connections and trust, and may still involve legal and professional ethical issues. 4. **Public testing programs**: Some brands may have public testing programs or beta testing programs, and you can try to apply to participate in these programs. 5. **Media and news**: Pay close attention to technology news and media reports, sometimes they may release internal news or leaks about upcoming products in advance. 6. **Professional network**: Through professional network platforms such as LinkedIn, keep in touch with industry practitioners, and you may obtain relevant information. However, you still need to pay attention to legality and professional ethics when communicating. In short, obtaining confidential information requires attention to legal and ethical norms, and illegally obtaining or using such information may lead to serious consequences.
