I am wondering if they are leaving it up to the app developers to code their widgets to be aware of whether the widget is located on the lock-screen and if security is on. They should provide some warning of the security issue (at least one time) when placing a widget.
So don't put widgets that contain sensitive data on your lockscreen...FYI, the Launcher app itself can read all content of the AppWidgets it hosts and can have vulnerabilities that allow other apps to access the data too - so its not like your sensitive data in gmail was entirely safe before you added the widget to the lockscreen.
These widgets are not present by default and one has option of adding them. So if you are not comfortable adding them there don't add. It's as simple as that! I personally like the choice of calender being there.
this is only a security concern if the user enables the widgets it seems... so what's the problem? if you care about security, don't use these widgets... simple. personally, i don't understand why anyone would use lockscreen widgets and bother with a PIN lock since it seems to defeat the purpose.
I wouldn't put the email on the lockscreen for the obvious reasons you highlight, but I am stoked you can use the camera app without unlocking. The only concern that your video didn't address was whether when you are in the camera app, you can look through the pictures already taken on the phone.
My Galaxy Nexus just got the ota update to 4.2. When you go into the camera app from lock screen, you cannot view pictures that were already taken. You can only view pictures that you take while in the camera app at that time.
So I re-read the article. I still don't understand the complaints. If you want quick access put it in the lock screen widgets. If you want security spend the 0.5sec it takes to unlock your screen. What is your answer to your complaints?
much ado about nothing re widget security. the point of having email via lockscreen is ease of access. if you care about security, not putting the email widget on the lock screen makes a lot more sense than limiting the widget.
