Here are some things I try:
Turn off Notifications.
Turn off location services except when navigating or calling the taxi.
Uninstall as many apps as possible, use browser.
Use adblocking anti tracking browser (I use Duck, alt suggestions welcome).
Report unknown / unwanted senders as spam.
That said, I am a NEWS ADDICT. There are four world leaders whose downfall I eagerly await, and frequently check the news for this ;-) .. you might be able to guess three but not the fourth.

Why are people not guessing
Putin
Trump
Xi
Modi
Replace Modi with Netanyahu and maybe Xi with Kim. These two are dictators but don't really care about things outside of their region (other than Chinese exploitation in Africa). They want to stay in power not take over the whole world.
Israel is abusing Holocaust guilt in Europe to get away with genocide and massive cyber ops against their own allies and open bribery in US elections. And North Korea is so insane that the power transition will be fun to watch. All the generals and family members are waiting on him to die, and when he does there might be a military coup or even a civil war.
Putin
Trump
Fico
Erdogan
