My Asus Zenfone 5 is beginning to have some malfunctions :

No more sound, which means :

  • I can't make calls (the phone freezes to black and I can only start it up again by holding the power button)
  • I can't receive calls (callers go directly to voicemail)
  • I can't open the camera to take pictures or videos
  • Alarms don't ring, they just vibrate
  • I can't listen to music
  • I can't watch videos (videos taken with my phone, on youtube, on any social media app...) : video just won't start.

I got this bug report from NewPipe, a youtube client :


  • User Action: play stream

I don't know if it's related, but I've also noticed that in the play store, when I check the the compatibility of any app with my device, it is identified as Asus UNKNOWN_PRJ_ID, instead of X00QD.

I don't know how to proceed from there, is my phone fixable ?

The last time it happened, I was able to fix the issue by shutting down and restarting the phone a dozen times, but this time it's not working.

  • There's a GitHub issue tracker related to this exception. According to them, it has something to do with low memory. Is this device running on stock ROM or custom ROM?

  • I am running on stock ROM, and have 4 GB of memory. Also it happened without bluetooth activated. Mar 19 at 15:05
  • Update : I think it's just that my phone is dying : it has also lost 4g capabilities (unless its very close to a tower) depite showing it has signal, SMS rarely works, accelerometer is gone... I was able to get it working again after a factory reset and countless restarts, but only for a few weeks, and the symptoms just started showing again May 15 at 8:55
