I don't think it addresses anything. It's just a firmware update. All I know is that 1.29 makes the capacitive buttons and the overall touch experience much better and much more responsive than 1.28. In fact, a lot of companies that sell glass or thick screen protectors require 1.29 because with 1.28 capacitive buttons become basically unresponsive or very hard to activate. May I ask what your CID is and where you live, or in other words where your device came from and if it is international or branded? I am considering going back to stock by flashing the Nandroid Backup and stock recovery but I'd have to change CID to one that already received that update. Thank you.
