Free Flash Drivers

So Ive been using Power Nap Xposed Module for a while and Ive noticed that that when Alarm goes off, then screen doesnt turn on (i.e I can hear the Alarm sound) but the screen remains dark. Ive to reboot the phone to get it working. Is there an app to be white listed under Power Nap. Also, Ive also disabled the Google Play Services wakelock under Privacy. Im sorry if this post has been created before. I couldnt find it even after searching.
