Hey friends here is a video on the Nokia 6.1 Plus Android Security Update March 2019.
I have found that overall performance has improved a bit but not significantly.
Two things solved on my phone viz. slow WiFi reconnect and carrier video calling.
Do let me if you have come across any other changes or improvements.
Do share if I have missed anything in the comments section.
