Please tell us some basic information before asking for help:

  1. Model Name: I01WD
  2. Firmware Version: WW-17.1810.2011.183
  3. Rooted or not: Not rooted
  4. Frequency of Occurrence: 100% reproducible
  5. APP Name & APP Version (If your issue relates to the app): Not applicable

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.


As the title suggests, the phone crashes after sending or receiving calls.

After a phone call, the system will eventually reach a point of instability, freeze and 'bootloop'. The only way to recover from this state is by using the hard reset button combination (Vol down + Power).

This issue will occur on stock, unrooted firmware as well as custom ROMs such as Lineage OS. I've attempted to monitor this behaviour via adb logcat but unfortunately I've not been able to find anything conclusive. I was led to believe that faulty hardware might be the cause, though according to the discussion thread below, it appears to have cropped up with the initial Android 10 firmware release:


There doesn't appear to be any conclusion to this prior discussion. @Anders_ASUS , I was wondering how this went in the end. You mentioned potentially solving this issue with an upcoming firmware update at the time, but I'm still experiencing this on the latest Android 10 firmware from December.

Additional, potentially relevant information:

Network: 3 UK

SIM slot: 2

SD card: Yes

Apologies for reposting, I'm not sure if my prior discussion threads are visible but they keep getting deleted or auto moderated.

Kind regards,
