I was very enamored with my Galaxy sII 10.1 tablet until I recently added my work email account which required I encrypt the device. Now it performs very slowly and frequently gets hung-up, so much so that I dumped the work email account. Is it true that in order to reverse the encryption I must do a factory reset? Will doing this reset solve my problem? What is the best manner to do the reset? Have there been any OS upgrades that I should install at the same time? HELP!!
