My definition of a custom ROM being unstable would be an app force closing or the phone has random reboots several times during a day when it has been stable on other ROM builds. When that happens, I nandroid back to a previous ROM or load a new ROM into my phone. So besides the obvious, how many reboots or FCs do you need to be convinced that a custom ROM is unstable. I also know that it some cases it is not due to the ROM itself that causes force closes or reboots such as the kernal being used or a unstable app. However, most of us who have been flashing ROMS for a while have a expectation on how a custom ROM should behave. So with that in mind, let me open up my first polling thread. YAY!
