What accessories do not work when I install Android 5.1 on my Iconia a100 /1gb ram

I currently have Kingroot in place. Newbie is overstating my abilities though I am adept with windows (all) and some DOS. I am looking to get away from ICS since my tablet doesn't even like it. I want all the accessories to work, camera, wifi, bluetooth etc. If not, I will stay in my soggy Ice Cream Sandwich
