I have a Coby Kyros MID1042 android 4.0 tablet, 8GB, 1MB RAM that is very slow. I have hardly used it since I got it. When you click, it hangs for a long time, then pops up a message "Browser not responding", "wait" or "close". Happens nearly every other click. Can't work with this. Can you tell me how to fix this? Can you add internal RAM like you can with a PC or laptop? I don't see anything that says you can, so I suspect not. (The Coby company is now closed) Thanks.
