So I have a Nextbook Ares 8 tablet that I am probably going to take back to Walmart. I've used it a few times now and only once has it worked right. I've used my phone and all works great each time so I know it's the tablet. Yesterday it gave me a battery error while flying and then at a different location it gave me a weak signal error while only 300 ft up and one hundred feet out in a wide open field. Switch to my phone and no issues. So I am in the market for another tablet. I'm debating between an iPad mini 2 and a Google Nexus 7. Any ideas which one is better or which one has a brighter screen??
