Sylvania is possibly the poorest quality, corner-cutting brand of anything you can buy, so you should expect this kind of thing. They have poor customer service for electronics too. Just read the reviews on Amazon.
My suggestions are either try to send it in for repair (best if it's under warranty) or try to sell it on Craigslist sometime soon and buy a better tablet. Unless you have good experience with computer hardware and touch screens, I wouldn't try to open it up and attempt to fix or replace parts yourself. You might be able to replace the faulty part(s), but the hard part will be identifying what's actually the problem.
I realized that after I had bought it._. sadly lol I'm deciding whether or not I really feel like messing with it since I don't use it much, but if I could fix it and/or get rid of the thing I think that's best. Thanks for your help
I've sent it back once before for memory issues before...and just after I get that fixed I killed the thing o.O Not sure how that happened and didn't crack the top, but whatever. Thank you. I think I'm going to go check out their site
