Lewa OS5 2 question [modding] topic

Hello i've installed Lewa OS5 on my ZP998 .

I was wondering of two things :

Why after switching off wifi my mobile data is disabled aswell? It's a feature or a bug? Can i fix it easly or not?


Can i change default sms / phone / callog app? I would like to use Textra and Android classic phone apk..



THANKS!
