I am facing a huge problem with my asus zenfone max pro m1. Yesterday I received a fota update regarding May android security patch and APN. After the update my sim is not working(no signal). I also checked if there is a problem with my sim by using it in other phones and there is no problem with my sim.

After the update I am not able to make calls or even receive(No signal).please help me to resolve the issue.


  • Hi, we'd request you follow the below steps:

    1. Clear system cache.

    2. Try the same under safe mode:

    Hold the power button for 5 seconds => When the screen flashes with option => Press & hold power option => You will get an option to restart in safe mode

    3. If still you face the issue factory reset your phone after taking a full backup.

    1. Model Name:ZB601KL
    2. Firmware Version:WW_Phone-16.2017.2005.082-20200506

    Can you please solve my queries.

    In my Asus zenfone max pro m1, Face detection is not working.

    When I open the face detection option , I can't even swipe down to agree.

  • Company एंड्रायड 10 कब तक टेस्ट करेगी कंपनी को कुछ प्ता नहीं बस टेस्ट पर टेस्ट मोबाइल का टेस्ट कर रहे या कंपनी स्वयं का टेस्ट कर रही है क्योंकि कंपनी जितने भी अपडेट देती है साथ में bug देती है

  • Hii This is not a Software bug. It is because of the hardware problem. This thing is already happened with me because of the antenna wire problem.

  • Company jab bhi koi security patch update bhejti hai to bug kyu aati hai , or abhi tak android stable update nahi aayi hai or company stable update ki testing kabtak karegi , other company kitni aasani se update deti hai or koi bug bhi nahi hoti hai

    After the FOTA update of may security patch I am facing huge battery drainage problem.i have once replaced my battery few months ago and it is a new one but now due to this update I lost the battery back up.such a disgusting approach from Asus we didn't expect it.such poor developers you have.And also A10 update that's also delaying.A11 has came but for us no A10 at all.

  • Its not a software problem. Can be problem in the hardware.

    Try resetting your phone.

    If it doesnt work, please contact the service centre.

    If that also doesnt work just throw the phone in the face of asus.

  • This new update also have problem on my max pro mobile data cannot turn on...i reset my network setting, clear system cache and i even reset my phone...the problem still the it okay because i downgraded my phone To 0.63 update..
