As you can see from both images, there is no cell signal but WIFI is on but somehow the phone thinks airplane mode has been turned on
This is the 3rd time is past few days and i have missed loads of calls as a result.
From what i can see from my apps, there is nothing that should be causing the issue.
Also, there doesn't seem to a root cause, It has happened while i was charging the phone and while the phone had been on constant use
I'm usually in low signal areas and when I move into an area where I know there is signal, it sometimes takes the device 30-60 seconds to recognize there is a signal.
This makes me think the radio polling interval is set fairly slow, perhaps in an attempt to save battery life.
I've used the airplane mode to toggle the radio and "wake it up" quicker than waiting the 60 seconds for the radio/phone to recognize the signal.
By any chance, are you in or around a low signal area when this occurs? I wonder if our two experiences might be related.
