How do police collect electronic evidence from mobile phones? Plug it directly into the computer and make a copy?

Hello, it depends on the case for evidence collection. For example, Didi taxi, if the driver is operating illegally, generally as long as the Didi software is on the mobile phone and the traffic law enforcement department detects it on the spot, even if the driver is operating illegally, a photo may be taken. . If other criminal cases, such as text message evidence, require mobile companies to provide relevant records, such as mobile phone WeChat, Alipay transfers, and red envelopes involved in the case, WeChat and Alipay companies are required to provide proof. So you need to look at the specifics. Some photos on your mobile phone can only be exported when it comes to cases. Some evidence is controversial and requires a third party to provide proof. I hope it can help you.
