Please tell us some basic information before asking for help:

  1. Model Name: ZenFone 9 16/256GB
  2. Firmware Version: VW_32.2030.2030.26
  3. Rooted or not: No
  4. Frequency of Occurrence: unpredictably
  5. APP Name & APP Version (If your issue relates to the app):

In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.


Double tap on the back only sometimes works even without the back cover of the phone. When I need this function to work, most of the time the phone does not respond at all even after tapping hard on different parts of the phone.



  • I see a similar issue, the Back Double Tap gesture is very inconsistent

  • I can confirm the same, whenever I need it, it doesn't work

  • Hey @Tomy90c, can you provide some more details like what sort of action have you assigned to the back double tap feature?

  • Alright, I've forwarded the issue to the R&D team.

    Hey @Tomy90c, I heard back from the R&D team. They require the following information to conduct a further investigation-

    • A video recording of the tapping method
    • Log details

    You can share these details via PM.

    Please follow the below steps to enable the built-in log tool (Bug reporter).

    1.  Open “Calculator APP”

    2.  Enter “.19595+=”

    3.  Select the Log type according to the type of issue you want to capture. “General cases” will work for most issues.

    4.  After your selection the log tool will exit so you can duplicate the issue or wait for it to happen. Try to use the screen recorder to show your issue when possible. If you can't screen record your issue, then please take a screenshot right after the issue has occurred (as a timestamp) so we know where to look in the log.

    5.  Navigate back to the log tool via calculator and Tap "FINISH AND SHARE".

    6. It takes several minutes for the log to generate. You can exit and do other stuff in the meantime. A silent notification will tell you once the process is done. Tap the notification and then the share button to upload the file to Google Drive and share the link with a moderator. Just make sure to change the permission first so that everyone with the link has permission to view it.

    Note: When you're no longer planning on logging your device, enter “.09595+=” in the calculator and the log tool will stop as well as deleting all stored log files. Make sure to share via calculator. The files found in internal storage -> asus_log are not the correct files (they are only 1.2kb)
