I recently installed GO Launcher for Tab and at first was pleasantly surprised by the results. But over the next few days I started noticing that certain basic functions either stopped working or starting acting erratically. IE, my stock browser started to freeze often and sites I used to be able to view either stopped working or would hang. Also there was an issue where my keyboard wouldn't respond. Now I've gone back to the stock browser and my Tab is working perfectly normal again but I wanted to see if anyone else experienced similar issues.
