I keep my app-count to a minimum. There are people who need every app imaginable, but that increases the attack surface of the phone. Try to minimize the amount of apps on your phone please!
Then of course all the usual OPSEC practices like not clicking on suspicious links in Whatsapp, E-mail or SMS always apply. You have to consider the human element of all this. So many people have been owned by fat-fingering some suspicious link in an SMS that then took over their phone.
But there is always the argument that: phones ship with malware anyway so you're pwned either way.
This happened months ago but I still can't see much info. Also, I see check point reported 4-5 issues to qcomm, not 400.
To people complaining android never gets updates: Android has been providing monthly security updates for some years now. It is even possible that this was fixed even faster since modern android can update some system libraries right from the store (Project Treble announced in 2017)
400 vulnerabilities! Good luck getting any reasonable percentage of users to install these patches. The software update situation on Android is horrible.Apple _just_ patched some really big zero-days.
Update: since this is getting down voted be skeptics, here are some sources for you

Additionally, because sales are much lower for iOS than Android, it's hard to get to the same scale. I don't know about iPad numbers, but 1 billion iPhones is about 5 years of sales, and five years is around where Apple stops providing updates (edit: as pointed out below, they're doing closer to 8 years from release now, but not all sales are from current model phones) and that combines with other factors and very few devices make it past five years of use.
The original version of the iPhone SE and the iPhone 6s are six years old now.
They run the current version of iOS and still work just fine.
It seems like even expensive flagship android devices get a year or maybe 2 of updates now and then you're just left on your own.
That's pretty cool - you can pay almost nothing for the s/w and still get a phone that works.
