I'm wondering if anyone else is having this issue with Widget locker. Since installing it, I've had my D3 come to a complete slowdown after unlocking the phone. When I check Running apps in settings, WL is using up 75-90 MB of RAM. Stopping and restarting it in the settings menu seems to fix it for a while. I also notice that WL can use from around 6MB to 30MB at any given time. If nothing is changing with configuration, why is there such a huge swing in RAM usage?
Another annoying issue with WL is that the clock widget provided has a cool swipe down feature to see your battery %. Unfortunately, it always reads 100%. Not so helpful.
