(M1) [ZB601KL] Phone not responding sometimes while phone call after latest 432 update.

While calling someone sometimes my phone not responding (not every time but 1 or 2 times a day). And can't see anything as LCD not turning on pressing power button. Even phone not charging that time. Only after pressing power button for 10-12 sec phone turning on. Without this method nothing working.


  • Me also faced this issue. In that time aeroplane mode also working. While calling sometimes after 30 seconds voice not audible to other side. In headphone working well. Please fix this issue.

  • Hi dipankarbasak007 and parthibanm19

    Thank you for your asking. Kindly provide the information below so that we can better assist you.

    1. Does the issue appear right after any system/apps' download or update?

    2. Does the issue appear with normal mode/earphone/speaker?

    3. Does the issue only appear in normal Call app or does it appears in any apps like Messenger/Whatsapp..?

    4. Please try to enter "Safe Mode". If the function works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.

    # How to enter and exit "Safe Mode"


  • 1) Only after dialing or receiving a call (but not everytime).

    2) Normal mode, earphone, speaker all three mode.

    3) only in normal call.

  • Hi dipankarbasak007

    1. As I mentioned above, if you access "Safe Mode", does the issue persists?

    2. Does the issue only appear in A10 V432 or does the issue appear in other firmware version before?
