about the solutions that i have,
camera initialization fix *first boot after install switch front to rear. then there is no longer a problem, even after reboots(for me at least)
sound *first time install (R1) I had to toggle the full volume up and down, then no problem since. Also had a bug on r7, calling someone, no one could hear, bug not present in r6 or r8+.
vibration *had a toggle in r6, idk why max removed it
rotation screen driver black out... no fix for me yet, but the capacitive display seems to function fine.(if you know what you are supposed to touch eg, back in the day when you used a samsung rom or from another phone, just touch it there, and it functions fine. A great example is papi jump.as the game ends, you get a black screen with buttons disregard and restart, submit score, and more great games.(something like that), you will get a screen that is black. You can touch the left side just above halfway of your screen, the game will restart fine. Also, if you hit the back button, you see a blue strip at the top and bottom, but everything in between is screwed.(a big black screen). I don't think it is rendering .9 patches properly in the screen.
