Exclamation Auto Hide Soft Keys + Mahdi Rom 2.4

Hello!

I have an Problem with the Mahdi-Rom 2.4.

An App called "Auto Hide Soft Keys" won't work with my Tablet anymore and says it doesn't support this hardware.
But this App works with the Stock Rom.

I think the Problem is the "Device Name".

With Stock-Rom it is shown in the Play Store as "LG G Pad 8.3".
With Mahdi Rom 2.4 "LGE LG-V500".

Anybody know how this could be solved?

Can i change this name anywhere?
