FOSS gamedev and creative worlds

Hello
Since the last update yesterday evening the Android Version is not working animore.
Media hangs at 50% and after 90Sec the Screen gets grey and im back at the Login Screen.
I f I try to open the Config Page the Screen gets gray and I am back at the Login screen.
The old Version functioned quite well.
I am using Android 4.1.1 on a Huawei Y300-0100
Minetest 0.4.10 (Minetest Mobile LLC)
Thanks,
JPR

Inofficial Android builds are not supported.

You must use the one here :
http://minetest.net/download

I´ve done that
By deinstalling the inofficial Build
Deleting the minetest folder.
Download the Package from your Homepage
and install it.

If I start it I get a grey line with yellow and after finish this the screen is black.
after sending the App in the Background and return to the foreground by touching the Home Button I am on the login screen.
The Config screen is working normaly.
But if I connect to a server Media hangs at 50% and after 2Minutes the app shuts down and I am back at the Start screen of my Phone.
what can I do to make it work again.
Thanks,
JPR
