I've had the Samsung Brightside for almost two years and it has worked just fine up until now. I took it out of my pocket today and it froze, so I turned it off and then turned it back on. After I did this though, the touchscreen wouldn't work at all, leaving me with no way to use my phone. My sister's phone had a similar problem, except now hers won't turn on at all. Is there anything we can try to do to get it working again?
