Been having these issues with my Galaxy S/Samsung Mesmerize since updating to the latest 2.3.5 firmware several days ago: -My screen will stay on for an undetermined amount of time regardless how many times I click on my "Power" button when I try and put it in standby/lock. Or, it will periodically takes screenshots when I'm trying to place it in standby. -My keyboard layout for Samsung and Android has changed dramatically. It looks nothing like it used to. -Prior to the update, I had approximately 20 apps I manually installed, none of which were saved to my SD card. Now, I can only install around maybe 12 or 13 before I get a message telling me there isn't enough available space on the phone itself to support any more apps. Also, how can I take a soundbyte from my SD card and designate it as my text message alerter? I've taken my phone into U.S. Cellular for this specifically, and not even their so-called "repair tech" can figure it out. I've read the manual and referenced numerous help forums for this issue, but can't find a solution anywhere. Thank you.
