關閉 / 刪除 Zenfone / ROG Phone 全局顯示 IMEI 浮水印方法筆記

由於華碩會在特殊的系統版本中加入全局顯示 IMEI 浮水印的功能，導致使用者在使用手機時會一直看到 IMEI 浮水印，影響使用體驗XD。

所以我在這邊紀錄一下關閉 / 刪除 Zenfone / ROG Phone 全局顯示 IMEI 浮水印的方法筆記。

• 一開始我先使用 dumpsys activity services | grep -iE "imei|watermark" 指令查看目前系統中有關 IMEI 浮水印的服務，抓到 com.asus.ims.watermark/.ImsWatermarkService 這個服務

ASUS_AI2301:/ $ dumpsys activity services | grep -iE "imei|watermark"
  * ServiceRecord{2b3bc26 u0 com.asus.ims.watermark/.ImsWatermarkService}
    intent={act=com.asus.ims.watermark.service cmp=com.asus.ims.watermark/.ImsWatermarkService}
    packageName=com.asus.ims.watermark
    permission=com.asus.ims.watermark.BIND
    baseDir=/system/priv-app/ImsWatermarkService/ImsWatermarkService.apk
    dataDir=/data/user/0/com.asus.ims.watermark
    infoAllowStartForeground=[callingPackage: android; callingUid: 1000; uidState: PER ; intent: Intent { act=com.asus.ims.watermark.service cmp=com.asus.ims.watermark/.ImsWatermarkService }; code:PROC_STATE_PERSISTENT; tempAllowListReason:<,reasonCode:SYSTEM_ALLOW_LISTED,duration:9223372036854775807,callingUid:-1>; targetSdkVersion:33; callerTargetSdkVersion:33; startForegroundCount:0; bindFromPackage:null]

• 嘗試使用 pm disable-user & am stopservice --user 0 -n com.asus.ims.watermark/.ImsWatermarkService || true & pm disable --user 0 com.asus.ims.watermark/.ImsWatermarkService 指令來停用這個服務，都沒有辦法成功停用

ASUS_AI2301:/ $ pm disable-user --user 0 com.asus.ims.watermark

Exception occurred while executing 'disable-user':

• 最後索性直接使用 pm uninstall -k --user 0 com.asus.ims.watermark 指令來刪除這個 APP，成功刪除後重啟手機，IMEI 浮水印就不見了。

ASUS_AI2301:/ $ pm uninstall -k --user 0 com.asus.ims.watermark
Success
ASUS_AI2301:/ $ reboot

C:\Users\EdwardWu>adb shell
ASUS_AI2301:/ $ dumpsys activity services | grep -iE "imei|watermark"
1|ASUS_AI2301:/ $
