Hi,
at the moment I am very frustrated. I have bought a LG G2 for testing purposes. But its not possible to use it with the Unreal Engine 4.5. The preview always fails (the push command hangs) and the built apks do not work. (When I start the installed program on my device I get a short black screen and then it jumps back to the program folder) I tried everything (ETC1, ETC 2 etc.) I used the normal “blank project” for my tests. As you can see nothing special. I didnt had these problems with my old Samsung Galaxy S3. On the LG G2 I am running Android 4.4.2.
