I currently have a problem with my HD2. Originally WM6.5 but the internet has figured out Android and for the most part it works very well (although I haven't used any other Android phones). I'm currently running the Hyperdroid GBX v12 build specifically for the HD2. Currently it's on Android 2.3.3

One scenario is this
1) Phone is in my pocket
2) BMW bluetooth has automatically connected when ignition is turned on
3) Phone rings and is answered in car via bluetooth
4) At the time the phone call finishes, the phone remains unlocked
5) Later the auto lock kicks in.

However I'm finding that the because the phone is staying unlocked for a period of time due to 4) and I'm making pocket calls. Likewise if someone calls me I have to remember to manually lock it before I put it back in my pocket.

Can anyone recommend an app(other than a very short lock time)? I don't see any setting that would prevent this in the normal configuration. I've not been able to find anything which suggests maybe I'm not doing something right.
