This bug does not affect in-game behavior in any way, so if necessary, it can be left to be fixed in the next version (to be changed when packaging the next version).
According to the new Minecraft versioning scheme, I believe the version name should be set to 26.1.1 when packaging the APK. However, the Android system "App info" displays it as 1.26.1.1, which incorrectly retains the old 3-digit prefix. This is likely a string formatting error.
Then,I can't update pictures so I will update pictures in comment.
