@508279079 can you take radio log? "logcat -b radio"

@508279079 I need some more explanation than that:

• Does the data switch not work?
• Does it work, but data still showing on notification bar?
• Does it work and notification bar is correct, but still can access internet?
• Some other alternative?

[508279079]

It work and notification bar is correct, but still can acces internet.
Please wait me to take radio log tonight.

I know what he is talking about. I think he is referring to a unofficial tutorial existing on the lenovo forum advocating user to set to a invalid APN (e.g. cmnet / three) in order to "disable" radio for a sim slot.

However, this does not keep the phone from searching for radio stations and thus bring no benefit, at all.

You may close this issue.

@508279079 thanks for reporting back!

The 20170811 version still has this problem, and I know how to reproduce it.
In this situation: Mobile data is on, 4G LTE Mode (Search in Settings) is on, using cmnet APN.
Reproduce: Turn on flight mode, then turn off flight mode. Turn off the mobile data, you will find that you can still go online.
