There a soft for that.
I use GPS Locker since a long time and there is an option to force update.
You can also change NTP server for the sever from your country (more precise) with FasterGPS (reboot after change)
Wouhou, I have my custom Redmi 3S.... that it mean EU ROM + ADBlocking + Magisk + Root + Xposed + ViperFX.
All perfectly works and phone is really smooth.
Just wait to test that with game optimization in new ROM...
Thanks for you work.
A little frustrated but it was why I installed EU ROM... for a relative stability (relative because I use Dev ROM on my and Stable on my wife phone) and of course no Chinese ads.
Be patient....
Have a good week.
