I can not update to 1.2.11.4 on Android 7.0

I am Japanese. This translation depends on Google translation. I am using Samsung's Galaxy s8. It was not possible to install if the recently released version 1.2.11.4 is Android 7.0. I tried to let my friend give me a Minecraft apk once and tried it but I could not install it because "Package is damaged". But when installing with Google Play, the test version of 1.2.13.6 was installed. The tester has been released. I do not know much about Android and I hope it will be corrected.I will put an image on it. It is a trouble such as updating is impossible.
