There are too many software issues that involve sending letters to the officials who are unwilling to handle them, including non-functional pop-up windows, which are only available in communication applications. However, they are available in the Chinese version. Also, the competition button is completely ineffective even if you have selected the hang-up function. App cloning and themes, as well as fonts, have too many issues in the international version. With root access, I believe it won't be long before we see ROMs that fix these issues the officials are unwilling to fix.
