I flashed my device with PR 1.3 yesterday, post about 4-5 months of CSSU testing usage. Few observations which I wanted to share. Please take these for what they are worth. Also understand that pre-flashing, my device had a long list of programs installed and perhaps my #2 can be attributed to things generally speeding up after a fresh flash: 1. With CSSU, typing from the homescreen would generally miss a character as Contacts showed up. For example, if I started typing Aiyush, Contacts would be looking for Aiush or Ayush (missing generally the second or the third character). Guess I can recall quite well that this never happened before CSSU and does not happen now anymore. 2. When double-tapping the power-key, around 30% of times the Power menu will come up (as if tapped only once) but the screen will not lock. Similarly when pressing the power key with screen locked, around 30% of times nothing would happen (unlock slider should appear). Again this problem has vanished after going back to PR 1.3 Again, I am not sure if there is a link between CSSU and the issues. I am laying those out so that this can be confirmed/rejected by other observers and perhaps serve as an input for the next release. Cheers!
