I've happily been using my Vtab since you guys talked me into buying one when Costco had them on sale, what, two+ years ago? Recently, I noticed it was booting up very slowly. Then updating the Apps got slower and slower. Now, the thing is just dragging, often getting stuck on the such and such app is not responding, close or wait, screen. I've been using GoLauncher EX and Dolphin browser. Apps are automatically updated. The tablet MAY run slightly faster on the standard, manufacturers browser, but not enough to make me believe that Dolphin is the only problem. Plenty of memory left on the Vtab. Nothing has changed with our wireless system and I do not have this problem with my android phone when I connect to the Internet using the same wifi system. Any ideas? This is making my Vtab virtually useless.
