WeChat on Android user agent string
Sites detect WeChat by the MicroMessenger token. On Android, Chrome/ and XWEB/ describe WeChat's built-in XWeb engine rather than the phone's Chrome app, and NetType shows the current network. This sample is from WeChat 8.0.76; newer versions use the same format. Below is the exact string it sends and what each part means.

String breakdown
| Fragment | Meaning |
|---|---|

Android 10 | Android 10. |
HJC-AN90 | Device model: HJC-AN90. |
Build/HONORHJC-AN90 | Device firmware build HONORHJC-AN90. |
wv | Android WebView marker — the page is shown inside an app, not a standalone browser. |
AppleWebKit/537.36 | WebKit rendering engine, build 537.36. Chromium browsers keep this token for compatibility. |
