A few things that I have noticed since using this rom out in the wild day to day, (mind you I am not a dev) I use the phone almost 24 x 7 , I use an external AC adapter to charge all batts and keep 4 standard OEM batts in rotation, alo use GPS, bluetooth, and tethering actively throughout the entire day, I do try to use wireless networks where available, but I am usually syncing non stop and running multiple apps...
I do not understand how, what , or why, but this particular release of Apex has led to my D2 constantly;y turning itself on when it was turned off. While I have a constant supply of batteries to keep things going, this is an annoyance because there are times where I do not want my phone vibrating, ringing etc. I have experienced this before on other GB kernel based roms for the D2 as well, so I am not sure what causes it.
Another issue , (but it has only happened twice) is when driving and using Navigation, the CRT screen off animation will jus repeat over and over, leaving the display useless, although directions are sill given. I keep the phone in the D2 car cradle mounted on the windshield, so I do not know if that would make any difference to how the phone uses proximity or accelerometer to keep screen on/off or portrait/landscape etc.
