New Gps Problem On Redmi 4x

[fabiopluda]

hello dear users
i have one strange problem on my Redmi 4X global version.
i use xiaomi.eu weekly roms, with magisk root
after miui9 update i have some strange problems with GPS. when I update to new rom, GPS stop working with my two daily sim card (TIM and TRE from italy). I have to shut up phone, change sim (WIND from italy) and restart phone. with this operation gps start to works again. then i can change and use my two daily sim cards.

i've tried cleaning completely the phone (incluse sd card), but problem still persist.
note: i have one Redmi 4 prime with same miui 9, i have zero GPS problems with this phone.

someone have some tips / solutions for me?
thanks.

EDIT: I've found a solution (and the bug).
I've inverted the sim position (SIM1 in SIM2 et vice-versa), set LTE internet on SIM2 and now GPS works!
It is finally a MIUI/modem BUG.

I have the same problem on the same device.
Xiaomi Redmi 4X with the latest 9.1.1.0 MIUI.

GPS suddenly stops working!

Also I don't have 2 SIMs just one.
