Hi, Very often the mentioned toggle buttons on status bar do not work. Regarding the GPS when I click the button nothing happens - no color change, nothng. I am not able to toggle GPS from the Settings as well. As for WIFI the toggle work, but the connection to the network never happens. When I go to WIFI settings I can see that WIFI network is being authenticated, then device is trying to obtain IP address - during this step the signal strength always go to just one notch above minimum. After few seconds the whole process restarts. If I restart the device everything is working for some time.
