TitanMPro The following link reports that Mozc is not available on recent GrapheneOS.

After running that through Lingva.ml, I see:
When the NoSheep Phone was shipped, it initially came with an app called "Mozc" installed for Japanese input, but this app has not been updated for a long time, and there are cases where it does not work with the latest GrapheneOS.
TitanMPro Is there any chance that GrapheneOS will fix this issue in the future?
I don't see a specific issue identified there. If, hypothetically speaking, the issue is that Mozc hasn't been updated in long enough that it doesn't run on Android 14, then I estimate it's 0% likely GrapheneOS will "fix" that issue.
Please note that I don't speak for the GrapheneOS project.
