Can't install app: conflict on app signature

[DyosangJed]

Can't install an Gallery at Calculator app even though the app is china version, I already tried the Global one. I also tried to uninstall both apps then install the updated one, but It doesn't allow me to continue. It says that I should uninstall the current version of the before installing the another one, I already said earlier that it is already uninstalled but the warning is still insisting.

System apps aren't meant to be updated. Do a search if you are interested about reasons etc.

So I have to wait for the ROM update to update the System apps?
