yesterday i have problem with my nexus 5
firts of all, i got carbon rom + elemetalx kernel
everything was ok until after 1 week suddenly my screen got many blank screen or black screen but if i push volume it had sound volume up or down. i decided to restart, but the problem still occur, until the next day my nexus 5 return to original state (like first install rom) the app still there though and return with play service fc.
i wonder what causing it,
fyi i reset my rom and everything ok again but still curious what happen
