I have a XIAOMI Redmi 4x with Global ROM version.

Unfortunately many Regions (Belgium / Netherlands / other) are missing and the Dutch language as well.

As language I'm always using English, so no problem there
For the Region, instead of Belgium I'm actually using Germany which has the same Time-zone.

From a hardware perspective (2G/3G/4G) there are no problems, all Channels supported.

But I would like to know what other problems I may encounter, what other unwanted results might occur due to the "wrong" Region used. Problems I can't oversee yet
