ASUS 5 Bug Report
Model: ZS620KL
RAM: 6G
Firmware/APP Version: PPR1.180610.009.WW_USER_90.10.138.175_20190117
Frequency of Occurrence: Always
Rooted: No
APP Name: -
Screenshot:
After successfully updating to android pie (OTA update) the phone has no network service whatsoever. It appears that the phone is somehow unable to power on its mobile radio (says turn off airplane mode everytime you try to place a call). I have tried the following methods:

1. Restart the phone several times
2. Tried switching airplane mode on and off several times.
3. Tried multiple sim cards and ran sim test successfully mutiple times
4. Tried switching on the Mobile Radio Power manually using *#*#4636#*#* but it does nothing
5. Booted in safe mode

This is for sure a software bug as others on this forum are facing the same problem. Here is a link to another discussion thread on this: https://www.asus.com/zentalk/for ... er%3D%26sid%3D1%7C5

If anyone has a solution to this would be extremly grateful. This is a major bug and is not expected from ASUS. Please fix this.

Hi Rohitshome,

We have highlighted this to our developer team.

The team would like to know if performing factory reset helping you.

If it does not work, we will suggest you further troubleshooting steps.

Let us know ASAP.

Hi,

Performing a factory reset did not help. I submitted the phone to the service center and they simply disconnected and reconnected the antenna connections to fix the issue and it worked. However the technician was of the opinion that the antenna wasn't loose in the first place. So I assume somehow the reboot process after the update doesn't work like intended and a physical disconnection and re-connection of the hardware fixes the issue.

The opening of the back glass panel has now made my camera blurry and I need to resubmit the phone. Overall this is turning out to be a bad experience. Hope you guys find a fix soon.

Radio is always bad in this phone. I complained so many times. The radio voice in Bangalore comes very distorted. Same channels have proper voice in other phones.

RE: No network service error (mobile radio off) in Zenfone 5Z

After restarting my phone the phone has no network service. It appears that the phone is somehow unable to power on its mobile radio (says turn off airplane mode everytime you try to place a call). I have the latest update in my phone that is 'WW_user_90.11.162.88_20190723' which I got it from service center just a month ago as last month I faced the same issue. I have tried the following methods:

Restart the phone several times
Tried switching airplane mode on and off several times.
Tried multiple sim cards and ran sim test successfully mutiple times
Also done factory reset.


This is 3rd time since I bought my phone, it's really frustrating. Please help in this also fix the same.
