I have 2 Sylvania 7 in tablets that I bought my boys for Christmas. I put in 8gb memory cards and I go into SAM 3.5 and try to download numerous apps. Each time it force closes. I get a message saying I need to upgrade to 4.0 which I have on one but the other won't let me for some reason and even with 4.0 I can't get anything but force close everytime. I have uninstalled and reinstalled... Still nothing. Getting frustrating.
