My sinuses are generally a pain, with meditation and breath control exercises I focus on breathing in with my mouth and my nose at the same time. I still find it more beneficial than just mouth breathing and usually I can start to take deeper breaths in through my nose further on in the session.
A lot of US carriers provide the OS updates with branding and junkware rather than the device manufacturer.
Also for others concerned about privacy, your carrier can push applets onto the SIM card itself which can do a lot. Malicious actors in the past have exploited devices via applets such as Simjacker and WIBattack
