Having problems with this tablet working for awhile then it will not work at all and shuts down apps and I figure it is having no internet connection. This tablet is my grandsons and they have no internet access at home. I will connect it and it will work for a few weeks and then won't work and everything shuts down. After the apps are installed they should not require internet unless they are updating. I have turned all the automatic update options off, but it still does this. Can anybody offer suggestions?
