I've had this tablet for about 3 weeks now and ive been experiencing this strange problem. About every 5 minutes, the screen becomes completely unresponsive for 3 to 6 seconds. Its happemed twice while writing this up to now, so its getting worse. After two weeks, I contacted samsung for some help, and they told me to do a factory data reset, meaning I lost everything I already put on my tablet, and it would most likely fix it because there was some sort of "glitch " in the device. I did this and it hasn't fixed the problem. They also told me that if it didn't work, to call a number to get it replaced. However, after doing some research, I found out its not only my device that does this, but others to. I heard of a guy who got his replaced and it did the same thing as the last one. So is this a problem with all devices or just a portion of them? Has anyone else experiences this? Is this a software issue in all devices that could be fixed in an update? I had anathor problem that does not happen to frequently, but is still strange. When I use the spen for prolonged periods of time, sometimes, the whole device stops recognizing my fingers, meaning when I exit an app, I cant even swipe through home screens. But for some strange reason, the s pen works fine with everything, but I xant even press the touch buttons with my fingers, just the s pen. I get around this by putting my tablet in sleep mode, then opening it back up, then everything works again. Im getting really pissed about this, because a 400 dollar tablet should not have such issues, and im even starting to regret buying this tablet.
