Hi all,

I recently purchased a XiaoMi Mi8 phone, it's China ROM. Everything is fine except the GPS signal is weak (totally not connectable) when I'm indoor. This is obvious to me as I play Pokemon GO.
I was using another low-end phone previously, and it works fine in door.

I was wondering is the China ROM is to blame for the indoor GPS problem? Do anyone has any similar experience and found a solution?
