i think there is a APN problem with Jio sim in roaming with m3 note

I've updated my device with newest firmware (5.1.12.0G) and I've noticed few changes...

First of all: Screenshot function doesn't work at all...
Second: When I want to delete some apps, deleting option (on the top of the screen) is written on Chinese language.
Third: Occasionally, my phone is loosing connection with my provider (once per day) and it looks like SIM card is disabled. Rebooting device solves the problem till tomorrow.
Fourth: Many things are improved... For example, battery life now's lot better than before, many translations, like Croatian that I'm using at the moment, are better, camera app have some new features etc...

All together, I was expecting a bit more stability from this "stable" version of ROM, but... All together, my overall experience with M3 Note now's a little bit better than before.

New update and new problems.

I have a problem with 3G. When i turn it on, after 10-15sec it turns off with a SIM card.
I read that many people have the same problem.
In ukraine there is no 4G
With 2G there are no such problems.
