是否曾在街上使用微信掃描二維碼領取禮物？這可能意味著手機可能正在被監控。要解除監控，請按照以下步驟進行操作：

打開微信應用，進入設置選項。點擊「個人訊息與權限」，然後選擇「授權管理」。解除所有不需要的授權。返回設置選項，選擇「帳號與安全」。點擊「登錄設備管理」，再選擇右上角的「管理」（或「編輯」）。將所有非本人設備清除掉。完成上述步驟後，手機就能成功解除監控。

Have you ever used WeChat to scan QR codes on the street to receive gifts? This may indicate that your phone is being monitored. To remove the monitoring, please follow these steps:

Open the WeChat application and go to the settings. Click on "Privacy and Permissions" and then select "Authorization Management". Revoke all unnecessary authorizations. Go back to the settings and choose "Account and Security". Click on "Login Device Management" and then select "Manage" (or "Edit") in the upper right corner. Clear all devices that do not belong to you.

After completing the above steps, your phone will be successfully free from monitoring.
