Failure to inizialize!

Hi! Today i try to run simple project on Unity 5 (just camera and cube) on android 4.0.3 and i catch some bug on my samsung galaxy tab 2.0 10.1

Failure to inizialize!
Your hardware does not support this application, sorry!

So, anyone know, what it is?

This problem i find on this page too http://forum.unity3d.com/threads/performance-and-other-issues-unity-5-beta.276390/

7. Acer Iconia Tab A500:
If I try to “build and run” the app on the Acer Iconia Tab A500 (Android 4.0.3) the message “Failure to initialize! Your hardware does not support this application, sorry!” appears.
I tried to build the Android app with device filter Fat and only armv7. With Multithreading and GPU Skinning and without->no success. In Unity 4.5.5 the app worked. I’ve also tested the app on a Samsung S2, S3, S3 mini, S4 and a Nexus 4 without problems. Minimum API Level is Android 2.3.1 Gingerbread. Graphics level = automatic. Stripping level = Strip Assemblies.
Answer: Acer Iconia Tab is no longer supported

but he had this problem on UNITY 5 BETA

And last my question. Does unity really stop support old device, or maybe this just some bug?
Or maybe we must release our new project just for new device?

It looks like Unity decided to stop supporting non-Neon devices like Tegra-2 (Acer Iconia is one such device).

Here is the what’s new in Unity 5 page They make it clear (Dropped support for non-NEON CPU devices (e.g. Tegra 2). This gives a significant performance boost to Mecanim and PhysX among other things.)

This forum page has a list of all Tegra 2 devices that will not be supported by Uniy 5 builds.
