It seems to have helped bottom row of keys (send/menu/back/end).
A test I did before with my S2 and my GF's... send -> end -> send -> send -> end -> send... over and over.. Her's was fine... my send key would stop responding and feel "STUCK" down. With .428 on mine (after JL Wipe and resettofactory) and not loading any apps or data yet... my storm2 feels fine.
Pop-up letters for qwerty keyboard are back, and able to be turned on/off. Default setting is OFF. {home screen} -> Options -> Screen/Keyboard -> Show Key Indicator...
Load time is still very slow (seems slower than the original build)
bottom buttons are fixed
seems easier to type on
letter indicator works now.
bigger blue highlight on letters
