Please tell us some basic information before asking for help:
Model Name: Zenfone 6 (ZS630KL)
Firmware Version: 18.0610.2101.127
Rooted or not: not rooted
Frequency of Occurrence: always
APP Name & APP Version (If your issue relates to the app): Telephony Service 11.0.0.200924_1
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.
========================================
Since the update to 18.0610.2101.127, Telephony Service crashes using a 4G network for both SIM1 and SIM2 and the phone cycles between SIM/No SIM every 2 seconds. You have to force the device into 3G as preferred network in order to use the phone. SIMs are not faulty as they work in other devices. I tried factory reset and this did not resolve the issue.
Please help.
