my kindle fire is way out of warranty and has a custom rom on it. i use it as a radio type device as my nexus 7 does not seem to work with the app i use for some reason (maybe a kitkat problem) but lately ive been noticing that i have to get the microusb thing just right in the kindle and leave it. if i do as much as to barely move the table it will quit charging. (the cable works fine with my nexus 7) and the headphones jack is really loose (again the headphones work just fine with my nexus 7). i dont really want to have to live with this anymore (note: i am really careful with my kindle fire so that cant be a problem) but dont know what to do. help please?
