Here is what I observe after having installed metiCkOne's frg22d, and it is not going to be scientific.
1. I suspect the battery meter accuracy reflects the remaining capacity correctly. The issue exists in frg01b builds and frg22d. However, p3d's (frg22d) build appears to be less skewed among all.
2. The home screen at times did not display itself until either pressing the "Home Button" or moving to one of the side screen. What might have caused this? It is kind of annoying especially when wanting to dial somebody and couldn't see the direct dial which are stored at the home screen.
If there is solution to either question above, please share your insights.
