New update dont fix this, still no double tap to wake up

Hi,
I start using second card sim and i see that if i have active mobile data connection on second sim, on first one nobody can call me.
Is any way to accept phone calls when second sim has mobile data turn on? (If mobile data stops when first card answers call it be ok)

Then i follow instructions and i have root that i want.
Thank you very much
