Hi all, I was wondering whether anyone else has experienced these strange issues with the lock screen. 1. When I press the lock (sleep) button on the side of the phone, the screen turns off, but often when I put the phone down straight afterwards it comes back on by itself. There are no notifications, messages, battery alerts etc either, it just unlocks and sits on the home screen. I'm not talking about the screen which pops up when you wave your hand over the phone either (I'll call this the purple screen) - the phone just unlocks itself and sits on the home screen shortly after I've locked it, as if I've very quickly swiped and unlocked the phone straight after locking it. 2. Often I will unlock the phone by swiping the screen etc, and the phone will then display the purple screen before finally unlocking and returning to the home screen. 3. When using an app, if I press the lock button and shortly afterwards press home button (on the front of the phone), rather than showing the lock screen, it shows the app I last had open before returning to the lock screen, where I can then swipe to open the phone again. These problems are all intermittent. It just seems as though the phone gets incredibly confused around the lock screen. The worst out of these problems is the phone unlocking despite having been locked. I downloaded an anti virus app but this says that there are no viruses etc on the phone. As a side issue - almost every time I open an app now I get a warning that there is 'no connectivity' or 'no internet connection'. It can take up to a minute to get coverage back after unlocking the phone. I guess it could be a network issue, but it's strange that it's started all of a sudden. Anyone had similar issues?
