The problem
Steps to reproduce
- put your phone to flight mode, let it rest for a short time
- disable flight mode
What is the current behavior?
The phone seems to switch to flight mode correctly (at least the symbols for wifi and the indicators for mobile connection disappear and plane appears). After disabling flight mode, the symbols reappear. The indicator for the first SIM is filled, the one for the second is empty, as if the SIM did not get a connection. The wifi-symbol is present as well, but when you pull down the notification area you see that there is the little "x" in the lower right corner. Opening the wifi-settings with long press on the wifi-symbol works, but the list of wifi-networks is not there. The blue stripe moving from left to right indicates that it is still working. Disabling and enabling seems to work, but it doesn't change anything. Furthermore, the symbols at the lower part of the screen (left arrow, circle, square) are not present. After a certain time the screen goes blank (sometimes the launcher shows up, but it is empty) and becomes unresponsive. Then the lockscreen comes up and the phone is able to connect to wifi and mobile connection. Unfortunately, one can't take screenshots, as pressing power+Vol- doesn't work in this state.
What is the expected correct behavior?
The phone should re-enable the networks and connect.
Technical informations
