Xiaomi 8 presses the volume button to grab the log.

When using the device normally, you don't need to actively grab the mobile phone log, but the system will record the operation of the mobile phone from the time it is turned on.

① Log capture method: enter * # * # 284 # * * in the dialing interface of the mobile phone and wait for about 1 minute;

② Log validity period: information about 15 minutes before the log capture time will be retained. If it is crawled outside 15 minutes, valid information cannot be recorded in the log;

③ Reproduce the problem before grabbing the log. For example, if the mobile phone can't make a phone call, then we need to try to make a phone call, so that the problem of not making a phone call can be reproduced at least once, and then start crawling the log;

(4) Restarting the mobile phone, brushing the mobile phone, shutting down and other operations will clear the log information before these operations.
